Polyethylene/sebs coated coconut shell powder particle blend foam material and preparation method thereof

Abstract

The invention discloses a polyethylene / SEBS (Styrenic Block Copolymer) coating coconut husk powder particle blending foaming material, which is prepared from the following raw material according to parts by weight: 60-80 parts of LLDPE, 20-40 parts of HDPE, 30-40 parts of SEBS, 10-15 parts of limestone, 15-20 parts of water glass, 5-10 parts of coconut husk powder, 1-2 parts of N-(beta-amino-ethyl)-gamma-aminopropyltrimethoxysilane, 5-8 parts of diantimony trioxide, 4-6 parts of trel-butylphenyl diphenyl phosphate, 5-8 parts of dioctyl nylon acid, 3-5 parts of foaming agent, 1-2 parts of di-tert-butyl peroxide, 2-3 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 lead stearate, 2-3 parts of micro wax, 3-5 parts of modified tree ash, and 1-2 parts of antioxidant 1010. The polyethylene / SEBS (Styrenic Block Copolymer) coating coconut husk powder particle blending foaming material produced in the invention is light and soft, high in strength, good in rebound elasticity, ideal in foaming effect, uniform in foaming, fine and compact, good in fire resistance, resistant to chemical corrosion, ageing-resistant and durable in use.

Description

technical field [0001] The invention belongs to the field of polymer material processing, and in particular relates to a polyethylene / SEBS-coated coconut shell powder particle blended foaming material and a preparation method thereof. Background technique [0002] 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, polyethylene foam materials still have shortcomings such as low strength, poor resilience, and uneven cells. Therefore, one of the development directions of polyethylene foam materials is to develop soft, high flexibility, high strength, and uniform cells. , small and dense closed-cell foam grades, and at the same time, various fields also put forward corresponding requirements for the flame retardancy of plastic ...
