High-elasticity foamed polyethylene material

Abstract

The invention discloses a high-elasticity foamed polyethylene material. The material is characterized by comprising the following substances by weight: 80 to 98 parts of high density polyethylene, 2 to 5 parts of hydro-quinoline, 15 to 21 parts of polyol ester of benzoic acid, 10 to 17 parts of acetylated monoglyceride, 10 to 18 parts of polytetrafluoroethylene, 3.5 to 11 parts of red phosphorus, 5 to 9 parts of zirconium oxide, 3 to 6 parts of vanadium phosphate, 1 to 3 parts of polyolefin, 3 to 5 parts of expanded pearl powder, 25 to 31 parts of graphite, 5 to 12 parts of redispersible latex powder, 10 to 16 parts of gypsum powder, 3.5 to 7 parts of perlite, 12 to 26 parts of chlorinated paraffin and 7 to 12 parts of silicone oil. According to the invention, a formula for the foamed polyethylene material is simple; raw materials can be thoroughly decomposed; the prepared foamed polyethylene material has no odor and good elasticity; a pressed product has good shapebility and a stable shape; and the material has the advantages of flame resistance, small density, light weight, heat insulation, etc.

Description

technical field [0001] The invention relates to a high elastic polyethylene foam material. Background technique [0002] High-pressure polyethylene, flame retardant, foaming agent, cross-linking agent and other raw materials are blended, and after banburying and refining, polyethylene hydrocarbon is foamed at a high rate of chemical bridging to form a network polymer structure , A product that balances open-cell bubbles. The existing high-pressure polyethylene chemically cross-linked foaming materials not only have the problems of complex process formula and high cost of raw materials, but also have problems of complex process, inability to increase the foaming temperature, inability to completely decompose raw materials, large environmental hazard factors, and high labor intensity. The most important thing is that the existing high-pressure polyethylene chemically cross-linked foaming materials cannot produce continuous rolls. If rolls are needed, the sheets must be glued ...

Problems solved by technology

The existing high-pressure polyethylene chemically cross-linked foaming materials not only have the problems of complex process formula and high cost of raw materials, but also have problems of complex process, inability to increase the foaming temperature, inability to completely decompose raw materials, large environmental hazard factors, and high labor intensity. The most important thing is that the existing high-pressure polyethylene chemically cross-linked foaming materials cannot produce continuous rolls. If rolls are needed, the sheets must be glued and processed again, which will not only increase labor intensity and waste materials, but also also increased the cost
