Abstract

The invention discloses an environment-friendly plastic material and a preparation method thereof. The preparation method comprises the following steps that 1, ball milling is performed on calcium sulfate and magnesium oxide through a ball mill, the ball milling time is 3-5 h, and the ratio of grinding media to the materials is 20:1-30:1; 2, 12-20 parts of polyamide-1010, 5-10 parts of polycarbonate, 4-9 parts of alkyd resin, 4-8 parts of polyvinyl alcohol, 3-8 parts of calcium sulfate, 4-10 parts of magnesium oxide, 2-6 parts of polytrimethylene terephthalate, 3-8 parts of tetrafluoroethylene-hexafluoropropylene copolymer, 2-6 parts of polybutyl methacrylate and 4-10 parts of polyparahydroxybenzoic acid are weighed by weight, all the components are extruded inside a double-screw extruder, and the extruded components are the environment-friendly plastic material. The obtained plastic material effectively overcomes the defects that the tensile strength and the elongation at break of the conventional plastic material are low, and the mechanical performance of the plastic material is improved.

Description

technical field [0001] The invention belongs to the field of plastic materials, and in particular relates to an environment-friendly plastic material and a preparation method thereof. Background technique [0002] Plastic materials have many advantages, such as light weight and small specific gravity; high specific strength, and the specific strength of many plastics exceeds steel; insoluble in water, chemical corrosion resistance, acid resistance, and alkali resistance. Non-conductive, it is an excellent insulating material; it does not conduct heat, it is an excellent thermal insulation material, and it can also insulate sound. It is relatively wear-resistant and has unique self-lubricating properties. Some materials have better fatigue resistance than steel. Due to these special properties of plastics, plastics are used in all kinds of industrial product packaging, agricultural surface films, water pipelines, household appliance casings, medical equipment, wires, cables,...
