であり、施工性、保存性にも優れているので汎用されて
いる。Incidentally, in products made from such mixtures, such as water and sewage pipes, the adhesive used to join the pipe bodies and their joints is polyvinyl chloride resin or a copolymer of vinyl chloride and vinyl acetate. So-called solvent-based adhesives, which are made by dissolving a resin in an organic solvent such as tetrahydrofuran, methyl ethyl ketone, cyclohexanone, or acetone, are widely used because they are relatively inexpensive and have excellent workability and storage stability.
（発明が解決しようとする課題）
しかしながら、上記従来の接着剤は、上記混合樹脂から
製せられた製品又は部材の接着に用いた場合は、これら

チレン樹脂との相溶性に乏しい為である。(Problems to be Solved by the Invention) However, when the above-mentioned conventional adhesives are used to bond products or members made from the above-mentioned mixed resins, they do not have sufficient adhesion to these materials. The main reason for this is
This is because the conventional adhesives described above have poor compatibility with polyvinyl chloride resins and chlorinated polyethylene resins.
したがって、施工後所定の接着力を発揮するまでに長時

ものもあまり高強度のものを期待することができないと
いう問題点があった。Therefore, there are problems in that it takes a long time to exhibit a predetermined adhesive force after construction, resulting in a decrease in work efficiency and that the adhesive force itself cannot be expected to be very strong.
本発明は、上記従来の接着剤の欠点を解消し、短時間で
所定の接着力が得られ、且つ高強度の接着力が得られる
ものを提供することを目的としてなされたものである。The present invention has been made with the object of eliminating the drawbacks of the above-mentioned conventional adhesives, and providing an adhesive that can obtain a predetermined adhesive force in a short time and also can provide high-strength adhesive force.
（課題を解決するための手段）
本発明の１は、塩化ビニル樹脂と塩素化ポリエチレン樹

00, an adhesive characterized by being made of a chlorinated vinyl chloride resin with a degree of chlorination of 62 to 70% dissolved in an organic solvent; An adhesive used for molded bodies made of a material made of a mixture of and chlorinated polyethylene resin,
The gist thereof is an adhesive characterized in that its main component is a polymethyl methacrylic resin having a molecular weight of 250,000 to 1,000,000 dissolved in an organic solvent.
本発明の１に於ける塩素化塩化ビニル樹脂としては、そ
の平均重合度が５００〜１４００の範囲になければなら
ず、平均重合度が５００に満たない場合は接着剤自体の
強度が低くなり、所期の接着力を有するものが得られず
、逆に１４００を超えると、溶剤に溶かして接着剤とし
被着体に塗布した場合、溶剤揮散後の体積収縮が大きく
なり、接着剤に応力が掛かるため、所期の接着力を有す
るものとはなり難い。The average degree of polymerization of the chlorinated vinyl chloride resin in 1 of the present invention must be in the range of 500 to 1400, and if the average degree of polymerization is less than 500, the strength of the adhesive itself will be low. If an adhesive with the desired adhesive strength cannot be obtained, and on the other hand exceeds 1400, when it is dissolved in a solvent and applied as an adhesive to an adherend, the volumetric shrinkage after the solvent evaporates becomes large and stress is applied to the adhesive. Therefore, it is difficult to obtain the desired adhesive force.
又、本発明の１に於ける塩素化塩化ビニル樹脂としては
、その塩素化度は、６２〜７０％の範囲になければなら
ず、塩素化度が６２％に満たない場合は、所期の接着力

体との相溶性が悪くなる。In addition, the degree of chlorination of the chlorinated vinyl chloride resin in 1 of the present invention must be in the range of 62 to 70%, and if the degree of chlorination is less than 62%, the desired degree of chlorination must be within the range of 62 to 70%. If the adhesive strength exceeds 70%, the compatibility with the adherend will deteriorate.
本発明の２に於けるポリメチルメタクリル樹脂としては

に応力がかかり、接着強度が低下する傾向にある。The polymethyl methacrylic resin in item 2 of the present invention must have a molecular weight within the range of 250,000 to 1,000,000, and if it is less than 250,000, the above-mentioned high strength cannot be expected, and vice versa. If it exceeds 1,000,000, the volumetric shrinkage due to solvent drying increases, and when the solvent dries after coating, stress is applied to the adhesive coating film, which tends to reduce adhesive strength.

いるので、塗布直後被着体の表面に於いて有機溶剤によ
る被着体同士の相互溶解が起こる。(Function) In the first aspect of the present invention, since the main component of the adhesive is a chlorinated vinyl chloride resin having a degree of polymerization in a specific range and a degree of chlorination in a specific range, polyvinyl chloride resin and chlorinated polyethylene resin are used. The polarity of the mixed resin with respect to the adherend becomes high, the wetting characteristics on the surface of the adherend are improved, and the extensibility of the adhesive when applied is improved. Further, since a chlorinated vinyl chloride resin having excellent compatibility with vinyl chloride resin is used, mutual dissolution of the adherends by the organic solvent occurs on the surface of the adherend immediately after coating.

ずる歪み応力も軽減することが出来る。In the second aspect of the present invention, polymethyl methacrylic resin having excellent compatibility with vinyl chloride resin is used as the main component of the adhesive, and a high molecular weight resin is used, so the adhesive itself has a high molecular weight. It becomes strong, and as a result, high adhesive strength can be obtained. Furthermore, since a high molecular weight material is used, the proportion of the organic solvent at the same viscosity as an adhesive component can be reduced, and therefore the thickness of the applied layer after drying can be made relatively thin to obtain the same adhesive strength. Therefore, strain stress caused by bending or temperature changes can also be reduced.

縮が出来る。(Effects) In the first aspect of the present invention, since the main component of the adhesive is a chlorinated vinyl chloride resin having a degree of polymerization in a specific range and a degree of chlorination in a specific range, polyvinyl chloride resin and chlorinated polyethylene resin are used. The polarity of the mixed resin with respect to the adherend becomes high, the wetting characteristics on the surface of the adherend are improved, and the extensibility of the adhesive when applied is improved. Further, since a chlorinated vinyl chloride resin having excellent compatibility with vinyl chloride resin is used, mutual dissolution of the adherends by the organic solvent occurs on the surface of the adherend immediately after coating. Therefore, it is possible to increase the adhesive strength to the impact-resistant resin, and to shorten the time required for the adhesive to exhibit a predetermined adhesive strength after being applied to an adherend.

る。In the second aspect of the present invention, polymethyl methacrylic resin having excellent compatibility with vinyl chloride resin is used as the main component of the adhesive, and a high molecular weight resin is used, so the adhesive itself has a high molecular weight. It becomes strong, and as a result, high adhesive strength can be obtained. Furthermore, since a high molecular weight material is used, the proportion of the organic solvent at the same viscosity as an adhesive component can be reduced, and therefore the thickness of the applied layer after drying to obtain the same adhesive strength is relatively thin. It's over. Therefore, strain stress caused by bending or temperature changes can also be reduced. Therefore, similar to the first aspect of the present invention, it is possible to enhance the adhesive force to the impact-resistant resin, and also to shorten the time required to develop a predetermined adhesive force after application. Cost reduction can be achieved.
