Novel high-performance plastic additive

Abstract

The invention relates to a novel high-performance plastic additive which is prepared from the following raw materials in parts by weight: 20-35 parts of light calcium carbonate powder, 3-4 parts of methacrylate, 0.5-1.2 parts of organic tin, 2-4 parts of calcium chloride, 4-6 parts of activated zinc oxide, 3-5 parts of silicon oil, 4-7 parts of organic antimony, 0.6-1.3 parts of sodium carbonate, 2-4 parts of methyl salicylate, 3-4.2 parts of glass fiber, 3-6 parts of artificial mica, 5-8 parts of propanediol, 2-4 parts of sorbitol, 6-9 parts of calcium oxide, 8-12 parts of stearic acid, 3-7 parts of filler and 4-7 parts of kaolin. The novel high-performance plastic additive effectively reduces the decomposition rate of the plastic, prolongs the decomposition time, improves the processing flowability, and has the advantages of high thermostabilization efficiency and low cost.

Description

technical field [0001] The invention relates to a novel high-performance plastic additive. Background technique [0002] Plastic additives are indispensable auxiliary materials in the plastics processing industry, such as polyethylene, polypropylene, and engineering plastics processing, strengthening, and modification, all need to add various additives accordingly. Especially polyvinyl chloride, because its decomposition temperature is very close to the plastic processing temperature, if no heat stabilizer is added, it will be severely decomposed during processing. The intermolecular polarity of polyvinyl chloride plastic is very strong. When processing soft products, a large amount of plasticizer must be added to reduce the intermolecular attraction, improve processability and soften the texture of the product. Plastic additives are used in plastic molding processing. occupies a particularly important position. But at present, most of the manufacturers of plastic additive...

Problems solved by technology

But at present, most of the manufacturers of plastic additives in my country are small workshop enterprises with small scale, backward production equipment and backward technology. Most of their products are general-purpose low-end products. The product quality is not stable enough and the variety is single. Further improvement is needed to meet market demand.
