Abstract

The invention belongs to the field of high-molecular materials, and discloses a polyvinyl chloride composite plastic and a preparation method thereof. The polyvinyl chloride composite plastic is prepared from the following components in parts by weight: 35-45 parts of polyvinyl chloride, 3-4 parts of sodium dihydrogen phosphate, 8-14 parts of tetramethyl siloxane, 5-12 parts of zinc oxide, 22-25 parts of low-density polyethylene, 6-13 parts of polyethylene wax, 3-4 parts of magnesium stearate and 13-17 parts of isobutyl methacrylate. The preparation method of the polyvinyl chloride composite plastic comprises the following steps of: fast mixing in a high-speed mixer; stirring; extruding through a double screw extruder; granulating, and the like. The polyvinyl chloride composite plastic prepared through the method disclosed by the invention has the advantages of better antibacterial property and higher tensile strength and can be used for the preparation of related products as an antibacterial plastic.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a composite plastic and a preparation method thereof, in particular to a polyvinyl chloride composite plastic and a preparation method thereof. Background technique [0002] As a variety of composite plastics, polyvinyl chloride composite plastics have a wide range of applications. Composite plastics with polyvinyl chloride as the main material have strict requirements on the antibacterial properties of composite plastics when they are applied to places that are in contact with the human body. . [0003] If the antibacterial properties of polyvinyl chloride composite plastics are poor in application, when the human body is exposed to too much, it will cause certain harm and affect people's health. [0004] The level of tensile strength also has a greater effect on the performance of composite plastics. The higher the tensile strength, the better the elasticity of composite plastic...
