High-strength heat resistant plastic and preparation method thereof

Abstract

The invention discloses high-strength heat resistant plastic and a preparation method thereof. The high-strength heat resistant plastic comprises raw materials in parts by weight as follows: 1-5 parts of tert-butyl peroxybenzoate, 80-120 parts of polyvinyl chloride, 10-15 parts of o-methylbenzene diol, 8-12 parts of dioctyl phthalate, 15-20 parts of ketone-based resin, 8-10 parts of modified rattan fiber, 30-50 parts of trichlorophenol, 1-3 parts of lead stearate, 0.2-0.4 parts of stearic acid, 30-50 parts of nitrile rubber, 1-2 parts of an antioxidant and 2-3 parts of a curing agent. Compared with the prior art, the produced high-strength heat resistant plastic product is cheap, and a production process is simple; the chemical property is still stable at the higher temperature, and no irritant gas can be volatilized.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a high-strength heat-resistant plastic and a preparation method thereof. Background technique [0002] Plastic refers to high-molecular-weight synthetic resin as the main component. Due to the low strength of the plastic pipe in the prior art, the pipe can only be used in the field of low-pressure pipelines. At the same time, it requires a large wall thickness and high cost. The disadvantage is more obvious on large-diameter pipes. [0003] As an important alternative material, plastic has many excellent properties, such as light weight and great plasticity, etc., but most plastics have a common weakness, that is, their chemical properties are unstable at high temperatures It is easy to produce irritating gas, such as plastic tea cups, space cups, etc. A plastic product with stable chemical properties, high heat resistance temperature and environmental protection is studied, that is, a ...
