Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermoplastic resin composite which has excellent creep resistance and adhesive strength and can be used as a packing, a joint material, a sealing material or a gasket.

[0002]

2. Description of the Related Art For packings, joint materials, sealing materials, gaskets, etc. that keep airtightness of automobiles, electric equipment, buildings, etc.,
Soft vinyl chloride resin, vulcanized rubber, etc. are used as the material. For these gaskets, a soft vinyl chloride resin and a vulcanized rubber are used alone by extrusion molding or injection molding or by vulcanization in a mold to be formed into a desired shape, which is generally used as a support substrate of metal, hard synthetic resin or the like. Often used with screws or fixed with an adhesive. However, natural rubber, nitrile rubber, chloroprene rubber, E as materials with excellent airtightness (sealing performance)
When using vulcanized rubber such as PDM, expensive vulcanization equipment is indispensable because it undergoes a vulcanization process during its production, and heating equipment is also necessary to obtain a sufficient vulcanization effect. However, the production efficiency is poor, resulting in an expensive product.

On the other hand, when a soft vinyl chloride resin is used, its productivity is excellent, but its creep resistance is inferior, and the sealing effect due to long-term use cannot be maintained. Further, in recent years, particularly in the automobile industry, there has been a strict demand for weight reduction of automobile parts for the purpose of improving fuel efficiency of automobiles, the use of resin parts has been spurred, and a resin that is easy to recycle from the viewpoint of resource reuse. Material development is desired. For example, when vulcanized rubber is used as an automobile part, recycling is difficult, and when a metal is used as a support for a soft resin, it is disadvantageous in terms of weight reduction. It was necessary to separate the two, and it was inferior in terms of recyclability.

[0004]

The present inventors impair the excellent characteristics of the chlorinated polyethylene elastomer composition, such as creep resistance, compression set, flexibility, moldability, weather resistance, low temperature characteristics and the like. After a thorough study of parts such as automobiles, electric devices, and buildings that can be recycled without being used, a chlorinated polyethylene elastomer composition having a large flexural modulus, that is, a composite of a hard thermoplastic resin, is lightweight. The present invention has been completed by discovering that it has the above-mentioned various physical properties, can be used for a long time in applications such as gaskets, and is easily recycled. That is, the object of the present invention is to provide high-temperature creep characteristics (compression set), weather resistance, excellent adhesive strength, and easy recycling, such as packing, joint material, sealing material or gasket (these are collectively referred to in the present invention. The object is to provide a composite of a chlorinated polyethylene elastomer composition and a hard thermoplastic resin which can be used as a gasket).

[0005]

SUMMARY OF THE INVENTION However, the gist of the present invention is that a thermoplastic resin having a flexural modulus according to JIS K7203 of 1000 kg / cm ² or more (hereinafter referred to as a hard thermoplastic resin). And chlorination degree 20-45
Thermoplastic resin composite obtained by compounding 100% by weight of crystalline chlorinated polyethylene having a heat of fusion of crystal of 5 to 35 cal / g and 5 to 150 parts by weight of plasticizer as a main component. The body and its manufacturing method.

The present invention will be described in detail. The thermoplastic resin which is a constituent requirement of the thermoplastic resin composite of the present invention is JIS
Flexural modulus measured based on K7203 is 1000
It is necessary to have a value of kg / cm ² or more, and it is desirable that the hardness is usually a hard thermoplastic resin having a JIS A hardness value of 70 or more.

Examples of hard thermoplastic resins include crystalline polyolefin resins, thermoplastic olefin elastomers, vinyl chloride resins, chlorinated vinyl chloride resins and the like. The crystalline polyolefin-based resin is produced by polymerizing an olefin such as ethylene, propylene, butene-1, pentene-1, 4-methylpentene by a conventional method, and specifically, low density polyethylene (density 0 .910 to 0.925 g / cm ³ ), medium density polyethylene (0.926 to 0.940 g / cm ³ ),
High density polyethylene (0.941 to 0.965 g / c
m ³ ), polypropylene, random or block copolymers of ethylene and propylene, and the like. The thermoplastic olefin-based elastomer is specifically a mixture of polypropylene and EPDM, and EPDM having a crosslinked structure may be used.

The vinyl chloride resin is produced by a conventional method such as suspension polymerization method, bulk polymerization method, fine suspension polymerization method or emulsion polymerization method of vinyl chloride or a mixture of vinyl chloride and a comonomer copolymerizable therewith. All that have been used are used. Examples of comonomers include vinyl acetates such as vinyl acetate, vinyl propionate and vinyl laurate, acrylic acid esters such as methyl acrylate, ethyl acrylate and butyl acrylate, methacrylic acid esters such as methyl methacrylate and ethyl methacrylate, and dibutyl maleate. , Maleates such as diethyl maleate, fumarates such as dibutyl fumarate, diethyl fumarate, vinyl ethers such as vinyl methyl ether, vinyl butyl ether, vinyl octyl ether, cyanation of acrylonitrile, methacrylonitrile, etc. Α-olefins such as vinyls, ethylene, propylene and styrene, vinylidene chloride,
Examples thereof include vinylidene halides or vinyl halides other than vinyl chloride such as vinyl bromide, and polyfunctional monomers such as diacrylic phthalate and ethylene glycol dimethacrylate. Of course, the comonomer is limited to those described above. Not a thing. The comonomer content is 30% by weight or less, preferably 20% by weight or less in the constituent components of the vinyl chloride resin.

The average degree of polymerization of the vinyl chloride resin thus produced is usually in the range of 400 to 8000. For example, when a composite is produced by a coextrusion method, the average degree of polymerization is about 400 to 1500. It is preferable to use one. The chlorinated vinyl chloride resin is produced by a method of post-chlorinating the vinyl chloride resin produced by the above method. The post-chlorination method includes, for example, a solution method in which a vinyl chloride resin is dissolved in ethane tetrachloride and reacted with chlorine gas, a dry method in which the vinyl chloride resin is reacted with chlorine gas while heating or irradiating light, and A liquid chlorine method in which chlorine gas is dissolved in a solvent under pressure to react with a vinyl chloride resin, or a vinyl chloride resin is suspended in a hydrochloric acid solution, and a water suspension method in which chloroform is added and chlorine gas is passed may be mentioned. The chlorinated vinyl chloride resin used in 1. may be chlorinated by any method.

It is desirable that the chlorinated vinyl chloride resin has an average degree of polymerization of the vinyl chloride resin before chlorination in the range of 400 to 1500 from the viewpoint of workability in producing a composite. The chlorination rate after chlorination is 60 to 70% by weight.
The range is preferably. If the chlorination rate is less than 60% by weight, the effect of improving the heat distortion resistance is small, 70% by weight.
If it exceeds, workability tends to be poor.

Further, the hard thermoplastic resin used in the present invention may be a mixture of chlorinated vinyl chloride resin and vinyl chloride resin. The mixing ratio of the two differs depending on the use of the composite of the present invention, but from the viewpoint of the effect of heat distortion resistance, it is desirable that the former content is 20% by weight or more, preferably 50% by weight or more, and particularly 70% by weight or more. Among these hard thermoplastic resins, the heat resistance of the composite of the present invention,
Considering deformation resistance and shape retention, it is preferable to use crystalline polypropylene, chlorinated vinyl chloride resin, a mixture of chlorinated vinyl chloride resin and vinyl chloride resin, and particularly crystalline polypropylene.

The hard thermoplastic resin described above may optionally contain stabilizers, lubricants, antioxidants, ultraviolet absorbers, foaming agents,
Colorants, impact modifiers, processing aids and the like may be added. A chlorinated polyethylene elastomer composition that is composited with a hard thermoplastic resin contains crystalline chlorinated polyethylene and a plasticizer as main components. The crystalline chlorinated polyethylene needs to have a chlorination degree of 20 to 45% by weight and a DSC method heat of fusion of crystal of 5 to 35 cal / g, preferably 5 to 25 cal / g. Is a polyethylene crystal residue, the so-called crystallinity is 10 to 75%,
It is preferably in the range of 10 to 50%. DSC (Differential Scanning Calorimetry) method The crystal fusion calorific value is the value calculated from the total crystal peak area of the DSC chart measured at a heating rate of 10 ° C / min using a differential calorimeter, and if it is less than 5 cal / g It shows that there is substantially no residual crystal.

The DSC crystal melting point described later means DS
It is the temperature showing the highest peak of all the crystal peaks when measuring the heat of fusion of the C method crystal. The crystalline melting point of the chlorinated polyethylene used in the present invention is in the range of 110 to 140 ° C. If the degree of chlorination of chlorinated polyethylene is less than 20%, the compatibility with the plasticizer is poor, the hardness cannot be lowered, and the weather resistance is poor. On the other hand, if it exceeds 45%, the rubber elasticity decreases and the desired compression is achieved. Permanent strain and low temperature characteristics cannot be obtained. Further, when the heat of fusion of crystal is less than 5 cal / g, the effect of improving compression set is lost, while when it exceeds 35 cal / g, the hardness cannot be lowered and the workability is remarkably poor.

The chlorinated polyethylene used in the present invention preferably has a DOP oil absorption of 25 or more. DOP
The oil absorption amount of the DOP oil absorption is expressed by the number of ml, which is the addition volume of the DOP which becomes a dumpling mass of the chlorinated polyethylene powder by stirring while adding DOP little by little to 100 g of the chlorinated polyethylene powder under the temperature condition of 23 ° C. A quantity of 25 or more means D
Even if OP25 ml is added, it does not become a lump and is in powder form, or even if it seems to be solid, a slight force,
It means to disperse on impact. The measurement method is
It was performed according to JIS K5101. DOP oil absorption 25
By using the above chlorinated polyethylene, low temperature characteristics of the crystalline chlorinated polyethylene elastomer composition,
Blocking resistance and extrusion moldability can be improved.

The plasticizer which is one component of the chlorinated polyethylene elastomer composition is not particularly limited as long as it is used for vinyl chloride resin, and for example, di-2-
Ethylhexyl phthalate, di-n-octyl phthalate, diisodecyl phthalate, dibutyl phthalate, dihexyl phthalate and other phthalate ester plasticizers; dioctyl adipate, dioctyl sebacate and other straight chain dibasic ester plasticizers; trimellitate ester Plasticizer; Polyester polymer plasticizer; Epoxidized soybean oil, epoxidized linseed oil, epoxy resin and other epoxy plasticizers; Triphenyl phosphate, trixylyl phosphate, tricresyl phosphate and other phosphate ester plasticizers Examples thereof include one type or a mixture of two or more types.

The amount of the plasticizer to be used is appropriately determined depending on the kind and amount of the additives to be used in combination, which will be described later, or the hardness of the intended product, but is 5 to 150 parts by weight with respect to 100 parts by weight of chlorinated polyethylene. The range of 15 to 75 parts by weight is particularly preferable. If the amount of the plasticizer is too small, a low hardness cannot be obtained. On the contrary, if the amount is too large, it becomes difficult to suppress the bleeding phenomenon.

The chlorinated polyethylene elastomer composition preferably contains a crystalline polyolefin for the purpose of improving its melt flowability and adhesion to a hard thermoplastic resin. As the crystalline polyolefin, those used in the above-mentioned thermoplastic resin can be used, and specific examples thereof include low density polyethylene, medium density polyethylene, high density polyethylene, polypropylene and the like, and JIS K676.
The melt flow ratio (MFR) measured on the basis of 0 is 0.01 to 100 g / 10 min, preferably 0.1 to 5
It is preferably in the range of 0 g / 10 min. Particularly, it is preferable to use high density polyethylene or linear low density polyethylene.

Linear low-density polyethylene includes ethylene and a small amount of other α-olefins such as C such as 1-butene, 1-hexene, 1-octene, and 4-methyl-1-pentene.
_A substantially linear copolymer obtained by copolymerization with at least one α-olefin of about _{3 to} C ₁₀ and having an alkyl side chain based on the above-mentioned other olefin in each main chain. Is. The amount of crystalline polyolefin used is 5 per 100 parts by weight of crystalline chlorinated polyethylene.
It is preferably 0 part by weight or less, particularly preferably 5 to 30 parts by weight. If the amount added is too small, the fluidity and adhesiveness are not significantly improved, and if it exceeds 50 parts by weight, the moldability tends to be poor.

The chlorinated polyethylene elastomer composition used in the composite of the present invention can further improve creep resistance and compression set by containing a rubber substance containing a tetrahydrofuran (THF) insoluble crosslinking component. it can. A rubber material containing a THF-insoluble crosslinking component is acrylonitrile-butadiene rubber (NB
R), methylmethacrylate-butadiene-styrene rubber (MBS), acrylic rubber (AR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), ethylene-vinyl acetate rubber (EVA), urethane rubber (U
R) and other various rubbers are produced by introducing a cross-linked structure into the rubber molecule by adding a polyfunctional monomer to the polymerization system during the production of the rubber, or after the production of the rubber, a cross-linking treatment with an organic peroxide. . Among these, it is desirable to use a compound having a crosslinked structure by adding a polyfunctional monomer at the time of producing a rubber substance. Particularly in the present invention, NBR
Is preferred to be used. The THF-insoluble cross-linking component is preferably 20% by weight or more of the rubber substance, preferably 50% by weight or more, and particularly preferably 80% by weight or more. THF
If the amount of the insoluble cross-linking component is less than 20% by weight, the effect of improving creep resistance is not clear, and it is desirable to use one having a high degree of cross-linking as much as possible.

The addition amount of these rubber substances is 400 parts by weight or less based on 100 parts by weight of crystalline chlorinated polyethylene,
It is preferably in the range of 20 to 300 parts by weight. If the amount of the rubber substance added is too small, the effect of improving the creep resistance is not recognized, and if it is more than 400 parts by weight, the processability and moldability of the elastomer composition tend to be poor. In addition,
If the chlorinated polyethylene elastomer composition contains 20 parts by weight or more of crystalline polyolefin or 100 parts by weight of crystalline chlorinated polyethylene, or contains a rubber substance, it should contain 15 parts by weight or more of a plasticizer. However, if the amount of the plasticizer is too small, the hardness is high and the elasticity of the elastomer composition may be impaired.

It is desirable to add a filler to the chlorinated polyethylene elastomer composition to the extent that compression set is not impaired. The filler has the function of absorbing an excessive amount of plasticizer and facilitating kneading and molding. Examples of the filler include carbon black, calcium carbonate, titanium oxide, talc, aluminum hydroxide, magnesium hydroxide, hydrotalcite, clay, silica and white carbon. The amount of the filler added is selected from the range of 500 parts by weight or less relative to 100 parts by weight of crystalline chlorinated polyethylene, and is preferably in the range of 10 to 200 parts by weight in consideration of various physical properties of the elastomer composition. If the addition amount of the filler is too small, the effect of improving kneading and moldability is small, and if it is more than 500 parts by weight, the moldability tends to deteriorate, and it is economical to add it within a range that does not impair the moldability. It is also desirable from the viewpoint of sex.

Further, various additives such as a stabilizer, a lubricant, an antioxidant, an ultraviolet absorber, a foaming agent, a flame retardant and a colorant may be added to the elastomer composition, if necessary.
To prepare a chlorinated polyethylene elastomer composition, crystalline chlorinated polyethylene and a plasticizer and, if necessary, the above-mentioned various additives are kneaded under a shearing force while being heated to a temperature above the crystalline melting point of the crystalline chlorinated polyethylene. It is desirable to do. By kneading under these conditions, an elastomer composition having excellent compression set and low temperature characteristics can be obtained. At a temperature below the crystalline melting point, the plasticizer penetrates only into the amorphous part of the crystalline chlorinated polyethylene, and the crystal structure after kneading does not change much, but it is heated to a temperature above the crystalline melting point and kneaded under shearing force. It is speculated that by doing so, a plasticizer penetrates into the crystal part and a new network structure between molecular chains is generated when the chlorinated polyethylene is recrystallized, and rubber elasticity such as compression set is improved. To be done.

The device used for mixing the above-mentioned compounding components may be any device as long as it can mix them substantially uniformly, and examples thereof include a Henschel mixer, a ribbon blender, a planetary mixer and the like. Are, for example, extruders, rolls, Banbury mixers,
An apparatus such as a kneader capable of kneading under a shearing force while heating is used. As a kneading method, add chlorinated polyethylene and various additives in the previous stage with an extruder having multi-stage addition ports,
A method of injecting a plasticizer at the latter stage can also be adopted.
The upper limit of the heating temperature is preferably within a range in which thermal deterioration of chlorinated polyethylene can be ignored, specifically, 210 ° C or lower. The kneading temperature is in the range of 130 to 210 ° C, preferably 150 to 200 ° C.

The thermoplastic resin composite of the present invention is a composite of the above-mentioned hard thermoplastic resin and chlorinated polyethylene elastomer composition. The method of compounding is, for example, a method of extrusion coating the above-mentioned chlorinated polyethylene elastomer composition on a strip-shaped or strip-shaped deformed or rod-shaped extruded hard resin molded article, a plurality of extruders of a hard thermoplastic resin and an elastomer composition. Co-extrusion using a method of compounding in or near the extrusion die, a hard thermoplastic resin and an elastomer composition to produce molded products by various molding methods, and joining the two by heat welding or an adhesive. Various methods such as the method are adopted.

Alternatively, the composite may be formed by so-called insert molding, in which a molded article made of a hard thermoplastic resin is set in a mold and then the chlorinated polyethylene elastomer composition is injection molded. In particular, a hard thermoplastic resin is formed in a strip shape or a strip shape, and a strip-shaped or strip-shaped deformed article made of an elastomer composition has a strip-shaped end portion welded or bonded to the strip-shaped surface, or a hard composite. The composite of a long structure in which the respective strip-shaped ends of the thermoplastic resin and the elastomer composition of the strip-shaped or strip-shaped irregularly shaped product are welded or adhered to each other is a gasket (packing, It has high utility value as joint material and seal material. Of course, the gasket is not limited to the above structure.
