Problems solved by technology

[0003] The current IXPE foam has insufficient adaptability in actual use. For example, its toughness still needs to be strengthened. Insufficient foam toughness will not only affect the use effect of the product, but also affect its service life, which has certain limitations; for this reason, we propose A kind of super toughness IXPE foam and preparation method thereof

Abstract

The invention discloses super-tough IXPE (Intermediate Cross-linked Polyethylene) foam and a preparation method of the super-tough IXPE foam, and relates to the technical field of foam. Comprising 15-18 parts of low-density polyethylene, 8-12 parts of an ethylene-octylene high polymer, 4-8 parts of carbon fibers, 2-6 parts of glass fiber reinforced plastic resin, 1-5 parts of an antistatic agent, 6-10 parts of a foaming agent, 1-2 parts of a foaming aid, 2-4 parts of zinc stearate and 3-5 parts of a cross-linking agent. According to the super-toughness IXPE foam disclosed by the invention, substances such as the carbon fibers and the glass fiber reinforced plastic resin are added into the effective components, so that the use toughness of the IXPE foam is effectively improved, and the use effect of a product is enhanced.

Description

technical field [0001] The invention relates to the technical field of foam, in particular to a super-tough IXPE foam and a preparation method thereof. Background technique [0002] IXPE foam is an electronic radiation cross-linked polyethylene foam material. It is made of polyethylene as the main raw material, with several other accessories that do not contain any harmful substances. It is mixed and extruded first. Through green and healthy irradiation processing technology, it uses The cross-linking produced by the action of ionizing radiation on the material changes the original structure of the base material and forms a reticulated independent closed-cell cell structure, which is a high-tech high-grade closed-cell foam material; [0003] The current IXPE foam has insufficient adaptability in actual use. For example, its toughness still needs to be strengthened. The insufficient toughness of the foam will not only affect the use effect of the product, but also affect its ...
