使用されている。(Prior art and its issues) PVC laminated metal sheets, which are made by adhesively laminating polyvinyl chloride (hereinafter referred to as rPVCJ) and steel plates, stainless steel plates, aluminum plates, etc., are used in a wide variety of applications such as home appliances, miscellaneous goods, vehicles, and construction materials. However, the above-mentioned PVC is generally used with a plasticizer mixed therein in order to improve its film formability and secondary processability.

If the sheet surface is inserted into a molded product made of ABS, polystyrene, polycarbonate, etc., and used in a state of contact such as screwing or butting, the plasticizer mixed in the PVC sheet will migrate to the molded product, causing damage to the molded product. There is a problem that environmental stress fractures such as cracking over time are likely to occur.

。In order to solve the above problem, measures have been taken such as using a plasticizer with a large molecular weight or blending an elastomer with remarkable elasticity instead of a plasticizer, but if the above-mentioned plasticizer with a large molecular weight is used, Since the amount of agent transferred is reduced, the environmental stress fracture of the molded product is improved to some extent, but the compatibility with PVC is poor and bumps are likely to occur on the PVC sheet surface due to poor dispersion. On the other hand, when an elastomer is used instead of the above plasticizer, film forming properties such as dispersibility in PVC and rollability during calendar processing are poor, and the resulting P

共重合体プラスチックシートを金属板に積層し、加熱圧
着してなるプラスチック積層金属板である。(Means for Solving the Problems) The present invention solves the above problems, and its gist is that a urethane-vinyl chloride copolymer plastic sheet with a Shore hardness of Hs 80 to 90 is laminated on a metal plate, and heated. It is a plastic laminated metal plate made by pressure bonding.
以下、本発明を具体的に説明する。The present invention will be explained in detail below.

記ウレタン−塩化ビニル共重合体プラスチックシートは
、ショア硬度Ｈｓが８０〜９０範囲であることを要件と
する。The present invention is formed by laminating a urethane-vinyl chloride copolymer plastic sheet on a metal plate such as a steel plate, a stainless steel plate, or an aluminum plate, and bonding the urethane-vinyl chloride copolymer plastic sheet with heat. requires that the Shore hardness Hs be in the range of 80 to 90.

レタン−塩化ビニル共重合体プラスチックシートのウレ
タン／塩化ビニル共重合比率が１／１．５〜１／２であ
ることが必要である。In order for the Shore hardness Hs to be in the range of 80 to 90, it is necessary that the urethane/vinyl chloride copolymerization ratio of the urethane-vinyl chloride copolymer plastic sheet is 1/1.5 to 1/2.

表面にプレッシャーマークを生じて外観品質が損なわれ
る。Shore hardness Hs is less than 80 (i.e. copolymerization ratio is 1)
/1.5 (the ratio of urethane increases), it is too soft, and when it is laminated to a metal plate and heat-pressed, pressure marks are created on the product surface and the appearance quality is impaired.
また、ショア硬度Ｈｓが９０を上回る（即ち、共重合比
率が１／２を下回ってウレタンの比率が少くなる）と硬
過ぎるために製膜性及び二次加工性が低下すると云う問
題がある。Furthermore, if the Shore hardness Hs exceeds 90 (that is, the copolymerization ratio is less than 1/2 and the urethane ratio decreases), there is a problem that film formability and secondary processability deteriorate because it is too hard.
（発明の効果） 本発明は、上記構成よりなるので下記効果を奏する。(Effect of the invention) Since the present invention has the above configuration, it has the following effects.

ンダー成形における製膜性など加工性に富むうえに、低
温時における二次加工性が優れている。That is, the plastic layer laminated on the metal plate in the present invention includes:
Since a urethane-vinyl chloride copolymer plastic sheet with a Shore hardness of Hs 80 to 90 is used, it has excellent processability such as dispersibility and film formability in calendar molding, and is also excellent in secondary processability at low temperatures.
また、本発明のプラスチック層には移行性の可塑剤を一

し優れた効果を奏するものである。In addition, since the plastic layer of the present invention does not contain any migratable plasticizer, even if the product of the present invention is fitted into other types of plastic molded products and used in contact with other types of plastic molded products, such as screwing or butting, the product will not break down due to environmental stress. It solves the conventional problems and has excellent effects, such as not causing any problems.
