した。According to the constitution (composition) described in Table 1, the resin plate molded articles (A, B) containing carpet waste, thermoplastic elastomer waste and other constituent materials, and no thermoplastic elastomer waste are used. The physical property test result of the control (C) is shown. (A) has high specific gravity, large tensile strength and bending strength,
High Rockwell hardness. (B) has a specific gravity of around 1.0, a large Izod impact, and a high MFR. The control product (C), which does not use the waste thermoplastic elastomer, has poor mechanical strength, but has a large Izod impact and poor fluidity. However, the cost is low because all are recycled products. In addition,
(1) Tensile strength is JIS K 7162, (2) Bending strength is JIS K 717
1, (3) Izod impact was based on JIS K 7110, (4) Rockwell hardness was based on JIS K 7202, and (5) MFR was based on JIS K 7210 A method.

When the calcium carbonate content is high, the bending strength is improved, but the impact is weak and the fluidity is low. Specific gravity increases. It is not preferable that the mixing amount of calcium carbonate is 29% or more, since the impact strength and the resin fluidity decrease. Further, if the amount of calcium carbonate mixed is less than 9%, the cost increases.

High impact resistance. In addition, the cost is low because all the waste materials are used as raw materials. Therefore, it can be used in place of floor plates, partition plates, and other various synthetic resin members that have been conventionally used. Since the production of the resin plate having such excellent properties is made possible by using the scraps and trimming scraps of the carpet as raw materials, the material recycling rate can be improved and the cost can be reduced. The method for molding a resin plate of the present invention can be extrusion molding, injection molding, vacuum molding, and stamping molding, and is versatile.
