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

Abstract

The invention discloses a polyethylene / high impact polystyrene (HIPS) coated coconut shell powder particle blending foam material. The material is prepared from the following materials in part by weight: 60 to 80 parts of LLDPE (Linear low density polyethylene), 20 to 40 parts of HDPE (high-density polyethylene), 30 to 40 parts of HIPS, 10 to 15 parts of fluorite, 15 to 20 parts of water glass, 5 to 10 parts of coconut shell powder, 1 to 2 parts of tetraisopropyl di(dioctylphosphate) titanate, 5 to 8 parts of magnesium hydroxide, 4 to 6 parts of tris(dimethylbenzene) phosphate, 5 to 8 parts of tri-n-butyl citrate, 3 to 5 parts of foaming agent, 1 to 2 parts of benzoyl peroxide,0.5 to 1 part of imarcaptoacetate dioctyltin, 1 to 2 parts of zinc oxide, 1 to 2 parts of stearic acid, 2 to 3 parts of polyethylene wax, 3 to 5 parts of modified tree ash, and 1 to 2 parts of antioxidant DSTP. The polyethylene / HIPS coated coconut shell powder particle blending foam material is light in weight, flexible, high in strength, good in resilience, ideal in foaming effect, uniform in cell, compact, high in flame resistance, ageing resistant and durable.

Description

technical field [0001] The invention belongs to the field of polymer material processing, and in particular relates to a polyethylene / HIPS-coated coconut shell powder particle-particle blended foam material and a preparation method thereof. Background technique [0002] Polyethylene foam material has excellent physical, chemical and mechanical properties. It is strong, flexible, wear-resistant, has excellent electrical insulation, thermal insulation and chemical resistance, and is widely used in packaging, chemical, construction and many other fields. 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 softness, 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 retardant o...
