Abstract

The invention relates to the technical field of environment-friendly materials, in particular to a preparation method of a polyethylene modified high-strength composite alloy material, which comprisesthe following raw materials: modified polyethylene master batch, nylon 6 resin, inorganic filler, a chain extender, a coupling agent, a compatilizer and an antioxidant 1076. The polyethylene modifiedhigh-strength composite alloy material disclosed by the invention is high in shore A hardness, high in maximum bearing strength and high in elongation at break, so that the polyethylene modified high-strength composite alloy material has relatively high elongation at break and relatively high tensile strength at the same time, and the requirements of processing technologies such as injection molding, extrusion and wiredrawing are met; the impact toughness of the composite material is improved by the nylon 6 resin, so that the composite material has balanced physical and mechanical properties,and the molecular weight and relative viscosity of nylon can be effectively improved by adopting the chain extender, so that the defect that the physical and mechanical properties are reduced due tomolecular chain breakage in the nylon regeneration process can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a method for preparing a polyethylene-modified high-strength composite alloy material. Background technique [0002] Polyethylene has incomparable wear resistance, impact resistance, chemical resistance, and self-lubricating properties compared to other engineering plastics. It is widely used in various fields of the national economy, especially in wear-resistant transportation, equipment linings, and various mechanical parts. With unique advantages, the development and application of its products have broad prospects, and the development of new application fields is attracting people's attention. However, ordinary polyethylene materials have weak maximum compressive strength, poor impact and compression resistance, thick wall thickness, many consumables, and high cost. Contents of the invention [0003] The purpose of the present invention is to...
