Abstract

The invention relates to a preparation method of a biomass-containing plastic electric appliance casing. The preparation method comprises the steps as follows: (1) preparing raw materials; (2) preparation of biomass powder: milling biomass containing natural fibers with a ball mill, and performing drying to obtain the biomass powder; (3) modification of the biomass powder: placing the biomass powder prepared in step (2) in a high-speed mixer, adding an additive and mineral powder, performing premixing, and performing heating drying at the heating temperature of 70-170 DEG C for 10-15 min to obtain the modified biomass powder; (4) mixing and granulation: mixing and granulating the obtained modified biomass powder with PP (polypropylene) in granulation equipment at the granulation temperature of 165-250 DEG C; (5) injection molding: mixing the obtained biomass modified PP material with a PP injection molding production material, adding an additive for injection molding, and performing product preparation to obtain the biomass-containing modified plastic electric appliance casing.

Description

technical field [0001] The invention relates to a preparation method and application of a modified plastic electrical appliance housing containing biomass. Background technique [0002] The electrical casings currently on the market mainly include metal casings, plastic casings, and plastic casings. Among them, the price of metal shells is relatively high, and there are hidden dangers of electric leakage, and the amount of use in the market is decreasing. Some plastic shells have hidden environmental risks, and their market share has not been high. In comparison, most of the current electrical casings are plastic casings and are prepared by injection molding. Through modification and enhancement, most plastic electrical casings have functions such as flame retardant, anti-static, waterproof, and even drop resistance. However, the all-plastic electrical enclosures still have shortcomings in terms of poor air permeability, low strength, easy aging, poor recyclability, and hi...
