Abstract
The invention discloses a CPE (chlorinated polyethylene) coated quartz sand modified low-density polyethylene foam material. The low-density polyethylene foam material is prepared from the following raw materials in parts by weight: 60-100 parts of LDPE (low-density polyethylene), 0-40 parts of LLDPE (linear low-density polyethylene), 30-40 parts of CPE, 10-20 parts of quartz sand, 2-3 parts of vinyl tris(beta-methoxyethoxy) silane, 5-10 parts of triphenyl phosphate, 4-6 parts of 4,4'-oxydibenzenesulfonyl hydrazide, 2-3 parts of ammonium bicarbonate, 5-8 parts of n-butyl methacrylate, 1-1.5 parts of 2,4-dichlorobenzoyl peroxide, 2-3 parts of zinc stearate, 1-2 parts of calcium stearate, 1-2 parts of lead sulfate tribasic, 2-3 parts of polyethylene wax, 3-5 parts of modified tree ash, 1-2 parts of ultraviolet light absorber THUV-328 and 2-3 parts of antioxidant 264. The CPE-coated quartz sand modified low-density polyethylene foam material disclosed by the invention is light in weight, soft, high in strength and good in rebound resilience, the foaming effect is ideal, and bubble holes are uniform, small and dense, so that the CPE-coated quartz sand modified low-density polyethylene foam material is good in fire resistance, resistant to chemical corrosion and ageing and is durable in use.
Description
technical field [0001] The invention belongs to the field of polymer material processing, and in particular relates to a CPE-coated quartz sand 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 req...
