[Industrial Field of Application] The present invention relates to a water-stopping material that is suitable for stopping water at joints and joints in agricultural waterways, shield segments, culverts, culverts, humid pipes, and other waterways and has good workability. (1) Background Conventionally, sealing materials made of water-swellable rubber or water-swellable urethane resin molded into strips have been frequently used as water-stopping materials for joints in civil engineering work. However, when installing these waterproof materials, adhesive must be applied to the target area in advance and dried before being applied.
Not only does it have the disadvantage of poor workability, but it also requires the skill and skill of the worker to determine the compatibility of the adhesive and water-stopping material (i.e., selecting the appropriate adhesive) and the degree of dryness of the adhesive. There are many aspects where you have to rely on your intuition. The latter drawback may, in some cases, impose a large burden on the constructor, such as reassembling the segments. (21 Problems with the Prior Art) Therefore, in order to improve the shortcomings of known construction methods that use adhesives, a method has been proposed in which a butyl rubber adhesive is laminated on the waterproof material. Hand-applying method and...: The method using the old cross die is the only known method.In the hand-applying method, ■ molding and vulcanization of water-swellable rubber, ■...
Three steps are required: molding the tape-like adhesive material, manually laminating the tape-like adhesive material (2) on the water-swellable rubber 13 (2), and winding the laminate into a roll. In addition, even when a cross die is used, at least two steps are required: (i) molding and vulcanization of the water-swellable rubber, and (a) laminating an adhesive layer on the water-swellable rubber using a cross die, and then winding it into a roll. A process is necessary, and in any case,
This increases the cost of the product due to process control, storage and transportation of semi-finished products, man-hours, etc., and ultimately limits its use in terms of price. In addition, since the known adhesive water stop material goes through the above steps, the product is made by uniformly laminating an adhesive layer 3 having a rectangular cross section on one surface of a water-absorbing rubber etc. 2 having a rectangular cross section as shown in FIG. 1B. It is difficult to realize a complex structure with higher water-stopping performance. Moreover, the adhesive layer 3 protruded from the rubber layer 2, resulting in poor appearance. (Problem to be Solved by the Invention) The main problem to be solved by the present invention is to provide a means for producing an adhesive water-stopping material at low cost.
An object of the present invention is to provide an adhesive water-stopping material having a more complicated structure and having excellent workability and water-stopping performance.

[Structure of the Invention] (1) Overview In order to solve the above-mentioned problems, the method for manufacturing the adhesive water stop material according to the present invention is to separately separate water-swellable rubber and adhesive using separate extruders. The extrudate is extruded into two parts, and both extrudates are integrated within a common mouthpiece. Below, various matters related to the structure of the invention are categorized. I will explain. ■ Constituent materials The adhesive water stop material that is the object of the method of the present invention includes (a> vulcanizate rubber containing a super absorbent resin and (b) a self-adhesive adhesive as essential constituent materials. 2a) Vulcanized rubber constituting the vulcanized rubber material (a) includes natural rubber, chloroprene rubber, styrene-butadiene copolymer rubber, butadiene rubber, butyl rubber, isoprene rubber, ethylene-propylene-diene ternary copolymer rubber, etc. Generally, vulcanizable elastomers are used. (2b) Super absorbent resin Also, as the super absorbent resin which is another component of material (a), for example, known hydrophilic crosslinked network structures, such as Cross-linked acrylates, starch/acrylic acid salts) copolymers with carboxylic acid residues (and optionally hydroxyl groups, alkali sulfonic acid residues, and sulfonic acid residues) in the molecule, isobutylene/
Examples of usable materials include modified maleic anhydride copolymers, saponified vinyl acetate/acrylic acid ester copolymers, and water-swellable urethanes, but are not limited to these. (2c) Additional components The above-mentioned vulcanized rubber further includes a commonly used rubber crosslinked side,
Rubber vulcanization accelerators, fillers, softeners, anti-aging agents, pigments,
Contains swelling aids, etc. (2d) Adhesive Adhesives include butyl rubber, halogenated butyl, rubber, natural rubber, isoprene rubber, and polyvinyl. General-purpose adhesive elastomers such as polyether, polyvinyl butyral, styrene/butadiene copolymer rubber, and styrene/isobutylene copolymer rubber are used. In addition,
Tackifiers such as ester gum and rosin, plasticizers (softeners) such as phthalate esters and chlorinated paraffin, various reinforcing agents, fillers, anti-aging agents, pigments, etc. are added to this adhesive elastomer as necessary. added. (3) Shape and structure The adhesive water-stopping material, which is the object of the present invention, can have various shapes and structures like conventional water-stopping materials, but in order to exhibit high adhesive performance and water-stopping performance, Figure 1A of the attached drawings
The super-absorbent resin-containing vulcanized rubber 2 shown in Figure A and L) in which the square-shaped space of the super-absorbent resin-containing vulcanized rubber 2 with a square cross-section is filled with an adhesive 3 having a plano-convex lens cross-section as shown in FIG. It is preferable to use a model ID in which dipping 4.4 is added to the back side of the rubber 2. Regardless of the format, a release paper 5 is pasted on the surface of the adhesive layer 3, and the entire tape is wound into a roll and cut to an arbitrary length each time it is used. be done. (Left below) 4 Manufacturing In order to carry out the method of the present invention, two extruders and a bonding die (die) are required. Regardless of whether the cross die 1o shown in FIG. 2A or the two-layer extrusion die 11 shown in FIG. 3 are bonded together inside each die, then wound up into a roll with a release paper 5 interposed between them, and then vulcanized in a vulcanizing can (not shown). After being laminated with UHF vulcanization equipment, hot air vulcanization equipment or fluidized bed (
Glass beads) may be passed through a vulcanizer or the like and wound up with a release paper interposed therebetween. Note that if vulcanization progresses during the product distribution process, the subsequent vulcanization step can be omitted. [Function] In the method of the present invention, the molding of the unvulcanized rubber layer containing a superabsorbent resin, the molding of the adhesive layer, and the bonding of both layers can be performed in a single process, so each operation can be performed individually. It is possible to significantly improve productivity compared to the case where the process is carried out, and it is also possible to significantly reduce costs caused by dividing the process. In addition, since the molding of the superabsorbent resin-containing unvulcanized rubber layer, the molding of the adhesive layer, and the bonding of both layers are performed between the respective materials in a plastic state, conventional manual bonding methods or bonding methods are not possible. Compared to the known method of laminating an adhesive layer using a cross die on a vulcanized rubber layer containing a superabsorbent resin that has already been sulfurized, more precise molding is possible, and as a result, the adhesive layer does not protrude. It is characterized by the ability to easily produce water-stopping materials with complex shapes and structures that have good thermal theory and water-stopping performance. [Example] Hereinafter, embodiments of the present invention will be described with reference to Examples, but the examples are merely for explanation and are not intended to limit the spirit of the invention. Example 1 (a) Water-swellable rubber compound The composition shown in Table 1 below was kneaded using a mixing roll. (Left below) (b) Adhesive formulation The compositions shown in Table 2 below were kneaded using an oven kneader. (c) Manufacture The water-swellable rubber compound and the adhesive compound are extruded into a predetermined shape using extruders on each side, and are joined together at the mouth part shown in FIG. 2B, as shown in FIG. Shape of A (thickness 4mm
Width: 20 cm; depth of dipping-shaped space: 1 cm x width: 16 mm>, rolled into a roll with a release paper in between, and heated using an indirect vulcanizer at an air pressure of 3) cg/cm at 150°C for 60 minutes. Vulcanization was performed under the following conditions. Table-1 *1 Manufactured by Sumitomo Chemical (Sumikagel R5P-520)> Table-2 Zoku Borisar Co., Ltd. Butyl rubber Example 1 Using an extruder, the compounded rubber shown in Table-1 was produced to a thickness of 3!I1m×
Extrude it to a width of 20 mm, and use an indirect can to air pressure 3.
kg/c12.The obtained vulcanized rubber containing super absorbent resin was vulcanized at 150°C for 60 minutes with a thickness of 1 mm x width of 20 m.
An m+ butyl adhesive tape was applied by hand to obtain a tape-shaped water stop material of type B in FIG. The cost coefficient of the water stop material of this comparative example was 3.5, with that of Example 1 being 1. Effects of the Invention As explained above, the present invention can provide a means for producing an adhesive water-stopping material at low cost, and also has a more complicated structure with particularly excellent workability and water-stopping performance. By providing an adhesive water-stopping material, it can contribute to cost reductions in civil engineering work, etc.
