Abstract

The present invention relates to the field of plastic products, and specifically relates to an anti-aging polystyrene plastic product; an anti-aging polystyrene plastic product of the present invention, and the present invention discloses a preparation method of a polystyrene product resistant to sunlight aging. Invented and optimized the formula of polystyrene materials, and used an organic rare earth composite stabilizer to improve the anti-sunlight aging performance of the material. This stabilizer can not only meet the processing requirements, but also is non-toxic, efficient, cheap, weather-resistant and Excellent plasticizing performance, certain internal lubrication and coupling compatibilization, which can effectively improve the comprehensive performance of the product.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to an anti-aging polystyrene plastic product. Background technique [0002] Polystyrene plastic is widely used in optical instruments, chemical industry and daily necessities, and is used to make tea trays, sugar bowls, soap boxes, cigarette boxes, student rulers, combs, etc. Due to its certain air permeability, when made into film products, it can also be used as a good food packaging material. [0003] CN200710156303.2 relates to an antistatic polystyrene composition, a preparation method thereof and a sheet prepared from the composition. An antistatic polystyrene composition, which is prepared by kneading the following components in terms of weight percentage: HIPS polystyrene 65.0-85.0%, polyethylene glycol monomethyl ether methacrylate 8.0% ~28.0%, 3.14~6.78% of hydroxyethyl methacrylate, 1.72~3.97% of sodium perchlorate, 0.0963~0.145% of azobisisobutyronitrile, and 0.92~2.4%...
