Abstract

The invention provides a composition for forming shock absorption foamed plastic. The composition is prepared from a base material component, a foaming agent, a bridging agent and a foaming aid. The base material component comprises a main base material and an auxiliary base material. The main base material is prepared from a styrene-ethylene-butadiene-styrene segmented copolymer and silicone rubber. The auxiliary base material is prepared from a polymer. The polymer is an ethylene-vinyl acetate copolymer or polyethylene or a vinyl acetate-ethylene-vinyl versatate copolymer or polyacrylate rubber or polyvinyl acetate or a composition of the former substances. The shock absorption foamed plastic formed by the composition for forming the shock absorption foamed plastic in the following process is not subjected to brittle fracture when impacted in a low-temperature environment, and good shock absorption capacity is kept.

Description

technical field [0001] The present invention relates to a composition for forming foam, in particular to a composition for forming shock-absorbing foam. Background technique [0002] Foam formed by plastic foaming has been widely used as a material for plastic products in daily necessities because of its light weight, wear resistance, and insulation. It is used in body protective equipment, sports equipment protective equipment or packaging materials for precision instruments and equipment. [0003] There is currently disclosed a composition for forming a shock-absorbing foam, which includes a base material component and an additive component, and the base material component is a styrene-ethylene-butadiene-styrene block copolymer (styrene-ethylene -butadiene-styrene block copolymer, referred to as SEBS), the additive components include fillers, bridging agents, foaming agents, foaming aids and bridging aids. However, the shock-absorbing foam formed by the above-mentioned c...
