Problems solved by technology
Traditional products made of polypropylene resin or polyethylene resin are increasingly restricted by the market and government
Although some degradable polypropylene resin or polyethylene resin products have appeared at present, they have not been widely promoted and applied due to their unsatisfactory degradability and other properties.

Abstract
The invention discloses a preparation method of modified plastic for a household electrical appliance housing. The preparation method comprises raw material preparation, drying, mixing, extrusion and sulfuration. The raw materials comprise 35-50 parts of polyolefin resin, 15-25 parts of polyethylene, 30-50 parts of chlorosulfonated polyethylene, 3-5 parts of hydrophobic modified nanometer level silicon oxide, 6-10 parts of benzoyl peroxide, 20-35 parts of a resin matrix PPB, 6-10 parts of a dispersant and 3-5 parts of calcium carbonate. The preparation method of the environmental protection material has simple processes and is convenient for operation. The environmental protection material has good mechanical properties such as notch impact strength, UV resistance and cold and hot shock resistance and good degradability and has good environmental protection effects.
Description
technical field [0001] The invention belongs to the field of modified plastics manufacturing, in particular to a preparation method of modified plastics used for housings of household appliances. Background technique [0002] At present, China has become a big country in the production and consumption of household appliances. Among the materials used in home appliances and other electronic and electrical products, the proportion of plastic consumption is relatively large. For example, the percentage of plastic weight contained in vacuum cleaners and refrigerators is about half of the total weight, so the amount of plastic materials used in household appliances is also quite large. However, whether it is metal materials or plastic materials, they must meet various environmental protection requirements. This is a problem that all Chinese home appliance companies and their industrial chain companies must face up to and face. Products traditionally made of polypropylene resin ...
