Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a coated molded product used for producing a hard coat type plastic product, for example.

[0002]

2. Description of the Related Art Conventionally, polycarbonate resin,
Polymethyl methacrylate resin, polyethylene terephthalate resin, polyvinyl chloride resin, acrylonitrile
Plastic products made of butadiene / styrene copolymer (ABS resin) and the like are used for various purposes because they are lightweight, easy to process, and have excellent impact resistance.

However, since such a plastic product has a relatively soft surface and is easily scratched, it is difficult to use it as it is in a field where surface characteristics such as abrasion resistance are required. Therefore, in order to improve wear resistance,
A technique of coating the surface of the plastic product with a high-hardness surface treatment agent is often adopted.

Of course, such a hard-coated plastic product may be used as it is, that is, in the form of a film or a sheet, but if necessary, it is molded into a predetermined shape before use. Sometimes.

[0005]

However, since the hard coat type plastic product has a high hardness of the coating layer, stress is concentrated around the bent portion of the coating layer during the molding process, and cracks are generated. However, there is a problem that the quality is deteriorated.

It is also conceivable that a plastic base material is molded into a predetermined shape and then a surface treatment agent is applied to cure the plastic base material. However, in this case, the surface treatment agent is applied to a plastic base material having a complicated shape. Another problem is that the coating work is very troublesome.

On the other hand, in recent years, Japanese Patent Publication No. 5-4350
As shown in Japanese Patent Publication No. 7, a UV-curable resin that is solid in an uncured state is applied to the surface of a plastic substrate to obtain a laminate, and the laminate is molded into a predetermined shape. A technique has been proposed in which irradiation is performed to cure the surface coating layer made of the ultraviolet curable resin.

However, the above-mentioned uncured ultraviolet curable resin has a high viscosity and is easily sticky, so that the handling work during the molding process cannot be carried out smoothly, and the uncured surface coating during the molding process etc. The layers are easily scratched,
There is a problem that a good appearance cannot be obtained.

The present invention solves the above-mentioned problems of the prior art, allows the handling work during molding and the like to be carried out without any trouble, and has a high surface hardness and excellent surface characteristics such as abrasion resistance, and further, the occurrence of cracks and the like. It is an object of the present invention to provide a method for producing a coated molded article which can prevent scratches and can obtain a high quality plastic product having a good appearance.

[0010]

In order to achieve the above object, the method for producing a coated molded article according to the present invention is specified by light such as visible light, ultraviolet light, or radiation such as X-rays, gamma rays or electron rays. A surface treatment agent containing an active energy ray-curable resin composition that cures when irradiated with an active energy ray and a thermosetting resin composition that cures when heated is applied to the surface of a molding substrate. To obtain a laminate, by irradiating the laminate with active energy rays to cure the active energy ray-curable resin composition component to semi-cure the surface treatment agent, and in the semi-cured state, A laminate is molded into a predetermined shape, and then the molded laminate is heated to cure the thermosetting resin composition component, thereby completely curing the surface treatment agent.

In the method for producing a coated molded article according to the present invention, the surface treating agent of the above laminate is irradiated with an active energy ray to cure the active energy ray-curable resin composition component to form a surface treating agent. It is semi-cured, and in the semi-cured state, it is molded into a predetermined shape. in this case,
Since the surface treatment agent, which is the surface coating layer of the laminate, is semi-cured, it does not become sticky and can be handled smoothly during molding, etc., and it is hard to get scratches and can maintain a good appearance. .

Further, in the present invention, the semi-cured surface coating layer has appropriate flexibility, so that the stress which tends to concentrate on the bent portion of the surface coating layer is dispersed in the periphery during molding. It is possible to effectively prevent the occurrence of cracks.

Further, after the laminate is formed into a desired shape, it is heat-treated to cure the surface coating layer completely by curing the thermosetting resin composition component, so that the surface coating layer is sufficiently cured. Hardness can be obtained, and a plastic product having excellent surface properties such as abrasion resistance can be manufactured.

The structure of the present invention will be described in more detail below.

In the present invention, as the molding substrate, any material can be used as long as it can be molded. However, in consideration of workability, vacuum molding, pressure molding, press molding, etc. A synthetic resin that can be molded by thermoforming, specifically, a polycarbonate resin, a polymethylmethacrylate resin, a polyethylene terephthalate resin, a polyvinyl chloride resin, an acrylonitrile-butadiene-styrene copolymer (ABS resin), or the like is preferably used. Can be used. Further, the molding base material may be transparent or colored, and the shape thereof is not limited, but a sheet shape, a film shape, a plate shape or the like is common. Further, the molding substrate may be provided with a pattern or the like by an appropriate means, if necessary.

The surface-treating agent in the present invention comprises an active energy ray-curable resin composition and a thermosetting resin composition.

In the present invention, the active energy ray-curable resin composition is defined by light such as visible light or ultraviolet light, or radiation such as X (X) ray, gamma (γ) ray, electron beam or the like. A resin composition that is cured by irradiation with active energy rays.

This resin composition is generally composed of an active energy ray-curable resin and a photopolymerization initiator blended therein. Of these, the active energy ray-curable resin is a photopolymerization agent. It is preferable to use a polymerizable compound that is polymerized or crosslinked by irradiation with an active energy ray in the presence of an initiator, and among them, a cationic polymerizable resin is particularly preferable.

Examples of the cation-polymerizable resin include ones or two or more compounds selected from epoxy compounds, cyclic ether compounds, cyclic lactone compounds, cyclic acetal compounds, vinyl compounds and the like. Of these, a compound having two or more epoxy groups in one molecule is particularly preferable. For example, well-known aromatic epoxy resins and alicyclic epoxy resins can be mentioned as suitable examples. Of these, specific examples of the aromatic epoxy resin include hydrogenated bisphenol A diglycidyl ether, 3,4-epoxycyclohexylmethyl-3 ′,
4'-epoxycyclohexanecarboxylate, 2-
(3,4-epoxycyclohexyl-5,5'-spiro-3,4-epoxy) cyclohexane-meta-dioxane, methylenebis (3,4-epoxycyclohexene), vinylcyclohexene dioxide, dicyclopentadiene diepoxide and the like. be able to.

These active energy ray-curable resins are
They may be used alone or in combination of two or more depending on the desired properties.

When an epoxy resin is used as the active energy ray curable resin, it is preferable to add a crosslinking agent for polyhydric alcohols. Specific examples of the polyhydric alcohol include 1,3-butanediol, 1,6-hexanediol, diethylene glycol, triethylene glycol, trimethylolpropane and pentaerythritol.

In the present invention, the photopolymerization initiator means an agent capable of releasing a substance which initiates polymerization upon irradiation with an active energy ray. Particularly when the active energy ray-curable resin is a cationically polymerizable resin,
As the photopolymerization initiator, an active energy ray-sensitive cationic polymerization initiator such as an onium salt or metallocene complex that releases a Lewis acid upon irradiation with an active energy ray can be preferably used. Specifically, triphenylsulfonium hexafluoroantimonate, bis (4-diphenylsulfoniophenyl) sulfide bishexafluoroantimonate and the like can be mentioned as preferable examples.

These photopolymerization initiators may be used alone or in combination of two or more kinds.

In the present invention, the photopolymerization initiator is 100 parts by weight of the above active energy ray-curable resin,
It is preferable to add 0.1 to 10 parts by weight, and the lower limit is 1
It is even more preferable that the amount is not less than 7 parts by weight and the upper limit is not more than 7 parts by weight. That is, if the blending amount of the photopolymerization initiator is too small, the surface treatment agent is not cured even by irradiation with active energy rays, the tackiness is increased, and the handling work such as molding may be difficult. On the contrary, if the amount of the photopolymerization initiator is excessively increased, no benefit is obtained and it is meaningless, which is not preferable.

In the present invention, the thermosetting resin composition means a resin composition which is cured by heating. This composition is generally composed of a thermosetting resin, which is crosslinked and cured by heating in the presence of a thermal polymerization catalyst, with a thermal polymerization initiator such as a thermal polymerization catalyst. Among these, as the thermosetting resin, for example, a cationically polymerizable resin containing an epoxy group can be mentioned as a suitable example,
Specific examples thereof include epoxy compounds such as 1,1,3-tetradecadiene dioxide, limonene dioxide, and polyglycidyl ether of polyhydric alcohol.

These thermoplastic resins may be used alone or in combination of two or more kinds.

In the present invention, the thermal polymerization initiator is
A compound containing a functional group that initiates polymerization upon heating. In particular, when the thermosetting resin contains an epoxy group, it is preferable to use a heat-reactive cationic polymerization initiator as the heat polymerization initiator. Specific examples of the heat-reactive cationic polymerization initiator include 4-chlorophenylbenzylmethylsulfonium hexafluoroantimonate, vinylbenzyl-4-methylphenylmethylsulfonium hexafluoroantimonate, cinamyldimethylsulfonium hexafluoroantimonate and 9-flu Olenyl tetramethylene sulfonium hexafluoroantimonate etc. can be mentioned.

Of course, these thermal polymerization initiators may be used alone or in combination of two or more kinds.

In the present invention, the thermopolymerization initiator is preferably added in an amount of 0.1 to 10 parts by weight, based on 100 parts by weight of the thermosetting resin. The lower limit is 1 part by weight or more and the upper limit is 7 parts by weight. It is even more preferable that the amount is less than or equal to parts by weight. That is, if the blending amount of the thermal polymerization initiator is too small, the surface treatment agent is not cured by the heat treatment and sufficient surface properties such as abrasion resistance cannot be obtained, which is not preferable. On the contrary, even if the amount of the thermal polymerization initiator is excessively increased, no benefit is obtained and it is meaningless, which is not preferable.

The surface treatment agent of the present invention contains the above-mentioned active energy ray-curable resin, photopolymerization initiator, thermosetting resin, thermal polymerization initiator and the like. , If necessary, various resin additives such as reactive diluents, curing accelerators, coloring agents such as pigments and dyes, defoaming agents, leveling agents, thickeners, flame retardants, antioxidants, ultraviolet absorbers, etc. ,
A modifying resin or the like may be appropriately added within a range that does not impair the performance of the above-mentioned compound.

In the surface treatment agent of the present invention, the mixing ratio of the active energy ray-curable resin and the thermosetting resin is 20 to 80 parts by weight of the active energy ray-curable resin when the total is 100 parts by weight. , 20 to 20 thermosetting resin
The amount of the active energy ray-curable resin is preferably 35 parts by weight or more and 65 parts by weight or less, and the thermosetting resin is 65 parts by weight or less and 35 parts by weight or more. That is, when the blending amount of the active energy ray-curable resin becomes too large and the blending amount of the thermosetting resin becomes too small, when the surface treatment agent is semi-cured by irradiation with the active energy ray, the coating layer The surface treatment agent as described above excessively cures, which makes subsequent molding processing difficult, which is not preferable. Conversely, when the amount of the active energy ray-curable resin is too small and the amount of the thermosetting resin is too large, when the surface treatment agent as the coating layer is semi-cured by irradiation with active energy rays. In addition, it is not preferable because the curing thereof becomes insufficient and the coating layer is too soft, and the coating layer may be scratched or sticky.

The surface treating agent having the above constitution may be laminated on the molding base material by an appropriate method. For example, the surface treatment agent is diluted with a solvent and laminated on the surface of the molding base material as a coating layer by a coating treatment method such as roll coating, flow coating, or dip coating to obtain a laminate (intermediate product).

In this laminate, by irradiating with active energy rays, the thermosetting resin component of the surface treatment agent for the coating layer remains uncured, and the active energy ray-curable resin component is cured to give a semi-finished product. Hardened state. Since the coating layer in the semi-cured state has an appropriate hardness, stickiness and scratches are less likely to occur, and subsequent molding processing can be performed without any trouble. In addition, since the coating layer in the semi-cured state also has appropriate flexibility, it is possible to disperse the stress that tends to concentrate on the bent portion of the coating layer in the periphery during the molding process, and to prevent cracks from occurring. It can be effectively prevented.

Here, as a method of forming the laminated body,
Well-known thermoforming methods such as vacuum forming, pressure forming, vacuum pressure forming, and press forming can be preferably adopted.

After the molding process, the laminate is heated to
The coating layer is fully cured by curing the thermosetting resin component of the surface coating layer. Thereby, a plastic product having a good surface hardness can be manufactured.

In the present invention, the laminate may be laminated and integrated with another substrate before, during, or after molding. As this laminating method, for example, a thermal laminating method such as press laminating or simultaneous extrusion laminating, or an adhesive laminating method using an adhesive can be suitably adopted.

By the way, according to the present invention, the surface treatment agent for the laminate is cured in two steps, that is, curing by irradiation with active energy rays and curing by heating. However, curing by irradiation with active energy rays is performed first. Therefore, it is necessary to carry out curing by heating later. That is, even if the surface treatment agent is semi-cured by heating and then molded and then irradiated with active energy rays, the coating layer (surface treatment agent)
The hardness is not sufficiently improved, and it becomes impossible to obtain sufficient surface hardness as a coated molded product. Although this factor is not known exactly, according to the inventor's view, heat is smoothly transferred to the inside of the surface treatment agent to improve the hardness of the entire coating layer, whereas the active energy ray is
It is considered that it does not penetrate into the inside of the surface treatment agent like heat and only improves the hardness of only the surface of the coating layer and cannot sufficiently improve the hardness of the entire coating layer.
