Polyethylene foam material and preparation method thereof

Abstract

The invention discloses a polyethylene foam material and a preparation method thereof. The polyethylene foam material is prepared from the following components in parts by weight: 80-100 parts of polyethylene, 20-30 parts of azodicarbonamide, 10-20 parts of medical stone powder, 10-15 parts of quartz sand powder, 5-15 parts of triethyl citrate, 5-15 parts of glass fibers, 20-40 parts of gedanite, 10-15 parts of bamboo fibers, 5-10 parts of a fire retardant, 2-6 parts of quinoline, 4-8 parts of ethylene vinyl acetate, 7-10 parts of polyhydric alcohol benzoate, 5-15 parts of stearic acid, 50-70 parts of a plasticizer, 10-20 parts of a cell nucleating agent, 10-15 parts of a lubricant, 5-10 parts of a cross-linking agent, 4-12 parts of a filling agent and 10-25 parts of a foaming agent. The product is free of peculiar smell, and has the characteristics of good material elasticity and good constancy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyethylene foam material and a preparation method thereof. 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 ...

AI Technical Summary

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
