Problems solved by technology

[0002] In the prior art, the wear resistance of plastic is limited, so metal parts are used on the cover plate at the bottom of the vacuum cleaner to increase its wear resistance, but at the same time it also increases its weight, which affects the use performance
However, if plastic is used, it is easy to be worn, scratched, etc. during repeated use, which seriously affects the service life.

Abstract

The invention relates to the technical field of plastic, in particular to a preparation method of a high-wear-resistance plastic piece. The preparation method comprises the following steps: preparingthe following components in parts by mass: 20 to 30 parts of ABS, 15 to 18 parts of polyamide, 13 to 16 parts of polycarbonate, 6 to 10 parts of silicon lime, 12 to 45 parts of polyvinyl chloride resin, 2 to 6 parts of rubber oil, 1 to 5 parts of 1,3-dihydroxy methyl-5,5-dimethyl glycolylurea and 2 to 4 parts of ethylhexyl stearate; forming: mixing the prepared components in a mixer completely anduniformly, conveying to an extruding machine, extruding particles by using the extruding machine, heating the particles to 180 DEG C to melt, injecting into a mode with the corresponding shape, maintaining the temperature to be 170 DEG C and the pressure to be 2 MPa for 0.3 minute, rapidly cooling to normal temperature and taking out of the mold. According to the preparation method of the high-wear-resistance plastic piece and through reasonable formula design and process design, the wear resistance of the plastic can be improved, so that the high-wear-resistance plastic piece is suitable forbeing used on a cover plate at the bottom of a dust remover, is not liable to scratch and wear in the repeated moving friction process, improves the use property and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a method for preparing high wear-resistant plastic parts. Background technique [0002] In the prior art, the wear resistance of plastic is limited, so metal parts are used on the cover plate at the bottom of the vacuum cleaner to increase its wear resistance, but at the same time its weight is also increased, which affects the use performance. However, if plastic is used, it is easy to be worn, scratched, etc. during repeated use, which seriously affects the service life. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a high wear-resistant plastic part with high wear resistance and light weight in order to solve the above-mentioned technical deficiencies. [0004] In order to achieve the above-mentioned purpose, the preparation method of a kind of highly wear-resistant plastic part designed by the present invention...
