Abstract

The invention discloses a high-strength plastic, and a preparation method and an application thereof. The high-strength plastic comprises, by weight, 30-40 parts of ABS resin, 5-10 parts of nanometertitanium dioxide, 5-10 parts of nanometer silicon carbide, 6-8 parts of calcium sulfate whiskers, 3-5 parts of epoxy resin, 2-6 parts of butyl titanate, 6-8 parts of chopped glass fibers and 3-5 partsof a dispersing agent. The high-strength plastic is obtained by mixing the raw materials in batches according to the parts by weight, heating, stirring and granulating. The prepared plastic has excellent bearing strength and tensile strength, and meanwhile, the thermal deformation temperature is as high as 231 DEG C; and the high-strength plastic can be applied to various fields such as automobiles, agriculture and living goods.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a high-strength plastic and a preparation method and application thereof. Background technique [0002] With the continuous development and progress of industrial technology, people no longer only use minerals as raw materials for various products. The emergence of polymer compounds has met people's growing needs. There are many polymer compound products in life, and it is often mentioned that The plastic is a polymer compound, and plastic is ubiquitous in life, from the light-transmitting film of the greenhouse in agriculture, various packaging boxes to the parts of automobiles and planes. Especially in automobiles and factory machines, plastics replace a large number of metal materials as components, because plastics are lighter and cheaper to manufacture than metals. But the existing plastic also has certain problems, that is, its strength is still not comparable to that of metal. Th...
