Abstract

The invention discloses a POE-coated nano argil modified low-density polyethylene (LDPE) foamed material which is prepared from the following raw materials in parts by weight: 60-100 parts of LDPE, 0-40 parts of LLDPE (linear low-density polyethylene), 30-40 parts of POE, 10-20 parts of nano argil, 2-3 parts of vinyltriethoxysilane, 5-10 parts of ammonium polyphosphate, 4-6 parts of p-toluenesulfonhydrazide, 2-3 parts of sodium bicarbonate, 5-8 parts of tributyl citrate, 1-1.5 parts of 2,5-dimethyl-2,5--di(tert-butylperoxy)ethane, 2-4 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 parts of dibasic lead phosphite, 2-3 parts of ethylene-bis-oleamide, 3-5 parts of modified plant ash, 1-2 parts of ultraviolet absorbent UV-0 and 2-3 parts of antioxidant DSTP. The POE-coated nano argil modified LDPE foamed material disclosed by the invention has the advantages of light weight, softness, high strength, favorable resilience, ideal foaming effect, uniform, fine and compact pores, favorable flame retardancy, resistance to chemical attack, aging resistance and high durability.

Description

technical field [0001] The invention belongs to the field of polymer material processing, and in particular relates to a POE-coated nano-clay modified low-density polyethylene foam material and a preparation method thereof. Background technique [0002] Low-density polyethylene foam has excellent physical, chemical and mechanical properties. It is tough, flexible, wear-resistant, has excellent electrical insulation, heat insulation and chemical resistance, and is widely used in many fields such as packaging, chemical industry, and construction. However, at present, low-density polyethylene foaming materials still have shortcomings such as low strength, poor resilience, and uneven cells. Therefore, one of the development directions of low-density polyethylene foaming materials is to develop soft, high-flexibility, high-strength materials. , a closed-cell foam grade with uniform cells, small and dense, and at the same time, various fields also put forward corresponding requi...
