Plastic containing calcined oyster shell powder, plastic product and manufacturing method of plastic

According to some embodiments of the present invention, the plastic contains the oyster shell calcined powder, the polyvinyl chloride and the acrylate copolymer, such that the antibacterial property of the plastic can be improved, and the problem of gas spots caused by the oyster shell calcined powder can be avoided. The embodiment of the invention further provides a manufacturing method of the plastic. The manufacturing method comprises the following steps: providing the oyster shells; the oyster shells are calcined, and oyster shell calcined powder is obtained; and smelting the oyster shell calcined powder, polyvinyl chloride and an acrylate copolymer to obtain the plastic. If the oyster shell calcined powder is used as the antibacterial agent of the plastic, in the hard plastic, the processability and release property of the plastic are not affected, the thermal deformation temperature and rigidity of the plastic can be improved, and the thermal stability is good. 本发明内容的一些实施方式中提供一种塑料，包含蚵壳煅烧粉、聚氯乙烯以及丙烯酸酯类共聚物
