For example, as a thermoplastic resin sheet having these characteristics, a vinyl chloride polymer having a hydroxyl group or a carboxyl group in the molecule as disclosed in JP-B-53-42057 and JP-B-53-42058. A sheet obtained by molding a vinyl chloride resin composition obtained by kneading and blending the above and a crosslinking agent.

When the composition comprising this crosslinkable vinyl chloride resin is used, it is desirable that the crosslinking reaction of the sheet A has occurred at the stage before vacuum forming, for example, the sheet forming step and the laminating step.
【００１２】 シートＡに積層するための軟質塩化ビニル樹脂シート（シートＢ）は、真空成 形加工条件においてシートＡより流動変形し易いことが必要である。すなわち、 シートＢはその加工条件温度領域における粘度が、シートＡのそれよりも小さい ことが必要である。具体的には加工時における温度の溶融粘度を調べることによ って知ることができる。シートＢに用いる軟質の塩化ビニル樹脂は、例えば架橋 性の基を有さない通常の塩化ビニル系樹脂に、可塑剤及び必要に応じ安定剤、顔 料、充填材等の添加剤を均一に混合したものである。可塑剤の添加量は、塩化ビ ニル系樹脂の重合度、真空成形条件での流動変形性、複合シートの加工条件、複 合シートの用途等によって適宜選択決定されるが、通常塩化ビニル系樹脂１００ 重量部当り、３０〜１５０重量部の範囲が適当である。The soft vinyl chloride resin sheet (sheet B) to be laminated on the sheet A needs to be more likely to be flow-deformed than the sheet A under vacuum forming processing conditions. That is, it is necessary that the viscosity of the sheet B in the processing condition temperature range is smaller than that of the sheet A. Specifically, it can be known by examining the melt viscosity at the temperature during processing. The soft vinyl chloride resin used for the sheet B is, for example, a normal vinyl chloride resin having no crosslinkable group, and a plasticizer and, if necessary, additives such as a stabilizer, a face agent and a filler are uniformly mixed. It was done. The amount of the plasticizer added is appropriately selected and determined depending on the degree of polymerization of the vinyl chloride resin, the flow deformability under vacuum forming conditions, the processing conditions of the composite sheet, the use of the composite sheet, etc. A suitable range is 30 to 150 parts by weight per 100 parts by weight.

In the figure, 1 indicates a sheet A and 2 indicates a sheet B. For the composite, for example, the following method is adopted, and the lamination method is not particularly limited as long as it does not cause delamination or cracks during vacuum forming. (A) A composition of a crosslinkable vinyl chloride resin and a soft vinyl chloride resin are coextruded and molded. (B) The sheet B is heat-laminated on the sheet A. (C) The sheet A and the sheet B are bonded and laminated with an adhesive. (D) The sheet B is cast on the sheet A.
【００１４】 本考案の複合シートを真空成形するには、先ず複合シートを１３０〜２００℃ 、好ましくは１５０℃前後の温度で、真空成形が可能になるまで予熱し、次いで 流動変形しやすいシートＢの面を成形型に接触させて型内を減圧にし、複合シー トと成形型を完全に密着させる。真空成形品は、冷却した後取出される。In order to vacuum form the composite sheet of the present invention, first, the composite sheet is preheated at a temperature of 130 to 200 ° C., preferably around 150 ° C. until vacuum forming becomes possible, and then the sheet B which is easily flow-deformed. The surface of is contacted with the mold to reduce the pressure inside the mold, and the composite sheet and the mold are brought into close contact with each other. The vacuum formed product is taken out after cooling.
【００１５】[0015]
本考案の複合シートによれば、シートＢが真空成形可能なシートＡよりも成形 加工条件において流動変形し易い軟質の塩化ビニル樹脂シートで構成されている ので、成形型にシートＢの面を接触密着させることにより、成形型に刻まれた繊 細で微妙な凹凸まで正確に転写表現することが可能になり、真空成形、加圧成形 に極めて好都合である。そして、シートＡの架橋性塩化ビニル系樹脂の組成物を 適宜選択することにより、またシートＡを架橋、発泡等を行うことにより、耐光 性にすぐれ、柔軟性、風合い、感触等の要求性能に対しても対応できるようにな り、本考案の複合シートは、電気製品の部材、自動車内外装材、建築内装材等と しての利用価値が頗る高い。 According to the composite sheet of the present invention, since the sheet B is made of a soft vinyl chloride resin sheet that is more likely to flow and deform under the forming processing conditions than the sheet A that can be vacuum-formed, the surface of the sheet B is brought into contact with the forming die. By bringing them into close contact, it becomes possible to accurately transfer and express even the fine and delicate irregularities engraved in the mold, which is extremely convenient for vacuum molding and pressure molding. By appropriately selecting the composition of the crosslinkable vinyl chloride resin for the sheet A, and by crosslinking and foaming the sheet A, it is possible to obtain excellent light resistance and to meet required performances such as flexibility, texture and feel. The composite sheet of the present invention has a high utility value as a member of electric appliances, automobile interior / exterior materials, interior building materials, etc.
