（発明が解決しようとする課題）
しかしながら、上述の従来例１〜４にあっては、以下に
述べるような問題点かあった。(Problems to be Solved by the Invention) However, the above-mentioned Conventional Examples 1 to 4 had the following problems.

凸面、小アール部。That is, in Conventional Example 1, the work of laminating the rubber elastic body containing the thickness retaining material requires more time and labor than the lamination of m-fiber reinforced thermoplastic resin by hand layup, resulting in high costs. In addition, uneven surfaces and small rounded areas are created by using a thickness retaining material.
段付き部への積層は困難であり、実施てきる成形体の形
状か限られたものとなる等の問題点かあった。Lamination on the stepped portion is difficult, and there are problems such as the shape of the molded product that can be formed is limited.

ールテープでは接着力か弱い等の問題点かあった。In addition, in Conventional Example 2, it is difficult to wrap vinyl chloride tape around uneven surfaces, small rounded parts, and one-step portions, and the shape of the molded product that can be implemented is limited. There were some problems such as weak adhesive strength.
また、従来例３では、凹凸面、小アール部９段付き部等

能となるという問題点があった。In addition, in Conventional Example 3, it is difficult to wrap the film around the uneven surface, the small rounded part 9 stepped part, etc., and the shape of the molded product that can be implemented is limited. In particular, the wrapping around the joint is difficult. The problem was that it was impossible.

高くつくという問題点かあった。In addition, in Conventional Example 4, it takes a lot of time to form the meat Jγ into a three-dimensional shape, which is expected to be effective with the adhesive material applied and laminated on the outer periphery of the uneven surface. There is a problem with that. In other words, this adhesive material does not dry quickly, and due to its viscosity, it tends to sag when applied, and for this reason, it is extremely difficult to form the required thickness by laminating layers of -degree coating. Therefore, it is necessary to increase the number of times by decreasing the layer thickness of the coating layer, and therefore, as mentioned above, it takes a lot of time and effort to form the adhesive material, and the cost is high. There were some problems.

The purpose is to provide a resin molded body.

よって機械的強度（特に衝撃強度）が向上する。(Function) In the reinforced hard vinyl chloride resin molded product of the present invention, as described above, a soft vinyl chloride resin coating layer is formed between the hard vinyl chloride resin molded product and the fiber reinforced resin layer formed on the outer surface thereof. By doing so, it is possible to prevent the physical properties of the composite material from deteriorating due to tie-left bonding due to differences in physical properties, and the mechanical strength (especially impact strength) is improved due to the buffering effect of the soft vinyl chloride resin coating layer.

形成コストか低減化される。In addition, since the soft vinyl chloride resin solution dries quickly, a large amount of the solvent evaporates during spray painting and thickens to a viscosity that does not cause any sagging when attached to the hard vinyl chloride resin molding. However, a wall thickness (0.2 thick or more) that can be expected to have a buffering effect can be formed by one spray coating, and therefore, the cost of forming the soft vinyl chloride resin coating layer, which is the intermediate layer, is reduced.

の成形体への実施かＩｉ丁能となる。In addition, since the intermediate layer is formed by a coating layer, the outer surface shape of the hard vinyl chloride resin molding that becomes the forming surface is an uneven surface,
Even in the case where the small γ-ru portion has two stepped portions, the intermediate layer can be easily formed, and therefore, it can be applied to all molded products regardless of the shape.

うになる。In addition, as the soft vinyl chloride resin that forms the soft vinyl chloride resin coating layer, ethylene vinyl acetate copolymer resin and vinyl chloride M=I 11fi, which serve as an OF% agent, are used.
By using a kraft polymer product, it is possible to prevent the poor chemical resistance of vinyl chloride caused by general plasticizers.

般的にはＤＯＰ （ジ２−エチルヘキシル）やり。In order to form a soft vinyl chloride resin coating layer 2 on the outer peripheral surface of this hard vinyl chloride resin molded body l, a solution of soft vinyl chloride resin in a solvent such as methyl ethyl ketone is sprayed with a spray gun or the like. A soft vinyl chloride resin coating layer 2 having a uniform thickness is laminated along the shape of the outer peripheral surface of the hard vinyl chloride resin molded body l. In addition, DOP (di-2-ethylhexyl) is generally used as a plasticizer for soft vinyl chloride resin.

強度か得られた。A (dioctyl adipate) etc. are known, but if these plasticizers are used, the plasticizer will migrate to the hard vinyl chloride resin molded product over time, reducing chemical resistance. Or, if it is required to maintain the chemical resistance of the hard vinyl chloride resin molding, by using a kraft product made of ethylene vinyl acetate copolymer resin and vinyl chloride, which are not common plasticizers, It is possible to maintain chemical resistance. When this ethylene vinyl acetate copolymer resin content of 55% is used,

ＵＬ全企画 Ｕｎｄｅｒｗｒｉｔｒｓ’ Ｌａｂ。It is desirable to use unsaturated polyester resin as this F8 curable resin, but this unsaturated polyester resin has weak adhesive strength to soft vinyl chloride resin, which is a soft material, and has a low shear strength of around 15 kg/cm2. . There,
In order to increase the shear strength, it is desirable to use a primer at the interface between the soft vinyl chloride resin coating layer 2 and the #a fiber reinforced resin layer 3. In other words, by using, for example, an incyanate-based primer at the interface between both layers, it was possible to increase the shear strength to 35 kg/cm.This was applied to a VP50A elbow joint, and the product was repeatedly exposed to high temperatures. When a negative pressure test (inside the pipe 730 mm, 11 g, vacuum 4 + 1 atm. after 18 investigations at 90°C) was conducted, no blockage in the pipe due to interfacial peeling between the hard vinyl chloride resin molded body 1 and the fiber-reinforced resin layer 3 did not occur.
