Polyethylene/polybutylece terephthalate (PBT) coated coconut shell powder particle blending foam material and preparation method thereof

Abstract

The invention discloses a polyethylene / polybutylece terephthalate (PBT) 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 PBT, 10 to 15 parts of tourmaline, 15 to 20 parts of water glass, 5 to 10 parts of coconut shell powder, 1 to 2 parts of anilino-methyl-triethoxysilane, 5 to 8 parts of decabromodiphenyl oxide, 4 to 6 parts of di-butyl nylonic acid ester, 5 to 8 parts of epoxy octyl stearate, 3 to 5 parts of foaming agent, 1 to 2 parts of diperoxycarbamate, 1 to 2 parts of zinc oxide, 1 to 2 parts of calcium stearate, 0.5 to 1 part of dibasic lead phosphite, 2 to 3 parts of glycol tristearate, 3 to 5 parts of modified tree ash, and 1 to 2 parts of antioxidant 2461. The polyethylene / PBT 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 / PBT-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 ...
