Good-toughness plastic particle based on production of automobile parts and preparation method thereof

Abstract

The invention discloses a good-toughness plastic particle based on the production of automobile parts. Raw materials include (by weight): 70%-80% of a nylon material, 8%-12% of a toughening agent, 3%-7% of short glass fiber, 2%-5% of methyl phenyl vinyl silicone rubber, 2%-5% of cis-1,4-polybutadiene rubber, 2%-5% of a binder, 0.5%-1.5% of a toner and 0.5%-1.5% of a light stabilizer. The inventionrelates to the field of plastic processing technology. According to the good-toughness plastic particle based on the production of automobile parts and a preparation method thereof, the nylon material is used as a main material, short glass fiber is added to increase the strength, and methyl phenyl vinyl silicone rubber and cis-1,4-polybutadiene rubber are added to endow the product with excellent low temperature resistance. Meanwhile, cis-1,4-polybutadiene rubber endows the product with a certain elasticity. With the cooperation of the toughening agent, toughness of the plastic particle is greatly enhanced, and the plastic particle is not easy to crack. With the methyl phenyl vinyl silicone rubber combined with the light stabilizer, the plastic particle has excellent corrosion resistanceand ageing resistance and its service life is long.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to plastic particles with good toughness for the production of auto parts and a preparation method thereof. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or polycondensation reactions. The composition and shape can be changed freely. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. composition. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40%-100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a plastic granule with good toughness for the production of auto parts and its preparation method, which solves the problem that the existing plastics generally do not have relatively good comprehensive properties, such as impact resistance, toughness and durability. In terms of aging performance, etc., the overall performance is not uniform enough, and many plastic materials are mixed and distributed unevenly, and the quality of the finished product is not good.
