Degradable high-flame-retardancy foamed material

Abstract

The invention discloses a degradable high-flame-retardancy foamed material which comprises the following components in parts by weight: 33-56 parts of ethylene bis(stearamide), 15-29 parts of glass fiber, 5-11 parts of ethyl acrylate, 3-14 parts of diphenyl phosphate, 5-8 parts of chlorinated paraffin, 9-17 parts of redispersible latex powder, 10-17 parts of fatty acid amide, 3.5-7 parts of polymethylhydrosiloxane, 55-68 parts of high-density polyethylene, 2-6 parts of diammonium phosphate and 25-30 parts of silicon oil. The degradable high-flame-retardancy foamed material has the advantages of simple formula, completely decomposable raw materials, no peculiar smell, high elasticity, favorable forming property of the compaction product, high forming stability, flame retardancy, low density, light weight, thermal insulation and the like.

Description

technical field [0001] The invention relates to a foaming material with good degradable flame retardancy. 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...

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
