Abstract
The invention relates to a formula of a novel polypropylene plastic. The novel polypropylene plastic is prepared from the following components in parts by weight: 140 parts of polypropylene, 7 parts of molybdenum sulfide, 3 parts of lead sulfate tribasic, 4 parts of magnesium stearate, 4 parts of antimonous oxide, 5 parts of butyl titanate, 7 parts of polybutylene terephthalate, 5 parts of glass fibers, 3 parts of methacrylate-butadiene-styrene copolymer, 8 parts of butadiene thermoplastic elastomer, 7 parts of aminopropyltriethoxysilane, 2 parts of methyl methacrylate, 2 parts of benzophenonelight stabilizer, 2 part of hydroxybenzotriazole light stabilizer and 1 part of hindered amine light stabilizer. The plastic has the advantages of light plastic weight, stable chemical property, rustprevention, high hardness, good impact resistance, relatively good heat resistance, abrasion resistance, good insulation, low heat conductivity and the like; and the process is simple, does not needspecial processing, has low processing cost, and has the advantages of high economic benefit and good social benefit.
Description
technical field [0001] The invention relates to a chemical product, especially a novel polypropylene plastic formula. Background technique [0002] With the development of the economy, plastics have been widely used in industry and life. There are also many types of plastics, including those with flame retardancy and high temperature resistance. Excellent flame retardant plastics are used more and more. As a large class of general-purpose materials, polypropylene is widely used for its small specific gravity, easy processing, corrosion resistance, non-toxicity and excellent comprehensive performance. Ordinary polypropylene is easy to age under heat due to its active groups, but it is also easy to mutate with polypropylene after adding antioxidants, resulting in a decrease in the performance of polypropylene. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel polypropylene plastic formula. [0004] In ord...
