Abstract

The invention discloses a formula of modified polystyrene, which comprises polystyrene, an antioxidant, a filler, a foaming agent, a photostabilizer and an antistatic agent, wherein the antioxidant is N-phenyl-alpha-naphthylamine, the filler is talcum powder, the foaming agent is sodium lauryl sulfate, the photostabilizer is 2-hydroxy-methoxydiphenyl ketone, and the antistatic agent is polyoxyethylene sorbitan monostearate. According to the formula, the modified polystyrene has the advantages of antistatic property, aging resistance, low cost, favorable mechanical properties and the like.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a modified polystyrene formula. Background technique [0002] polystyrene is made of styrene monomer Synthesized by free radical polycondensation reaction polymer , the English name is Polystyrene, the Japanese name is ポリスチロール, referred to as PS. It is a colorless and transparent thermoplastic , with a temperature above 100 degrees Celsius glass transition temperature , so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes. [0003] In real life, various types of polystyrene products have been widely used, and polystyrene has also developed products in various fields, such as flame-retardant systems, modified systems, etc., making polystyrene become more and more popular in the production and application ranges. more expansive. [0004] In recent years, modified polystyrene has been wi...
