Wear-resistant electrostatic-resistant flame-resistant ultrahigh molecular weight polyethylene composite material

Abstract

The invention discloses a wear-resistant electrostatic-resistant flame-resistant ultrahigh molecular weight polyethylene composite material. The composite material is prepared by performing mixing on ultrahigh molecular weight polyethylene with a viscosity-average molecular weight of 3-3.5 million and an electronic-resistant material by an open mill to form a mixture, then adding a filling material, a novel bromine-based compounded fire retardant, and proper amount of flow modifier, coupling agent, compatibilizer and anti-oxidant, and processing by a double screw extruder, wherein ultrahigh molecular weight polyethylene accounts for 40-60 parts, the filling material accounts for 15-20 parts, the novel bromine-based compounded fire retardant accounts for 20-25 parts, the electronic-resistant material accounts for 5-15 parts, the flow modifier accounts for 5-8 parts, the coupling agent accounts for 0.2-0.5 part, the anti-oxidant accounts for 0.2-0.5 part, and the compatibilizer accounts for 0.2-0.5 part. The above raw materials are weighed according to the above ratio and are mixed by the open mill for forming the mixture, and the mixture and the raw materials weighed according to the above ratio are extruded by the double screw extruder for preparation of the composite material. The composite material is widely applicable to fields of mines, ships, coal and the like. The preparation technology provided by the invention is easy to control, high in production efficiency and stable in quality.

Description

technical field [0001] The invention discloses a wear-resistant, antistatic and flame-retardant ultra-high molecular weight polyethylene composite material. It specifically relates to a composite material with excellent mechanical properties, wear resistance, antistatic properties and flame retardancy, which can be widely used in fields such as mines, ships, and coal. Background technique [0002] Ultra-high molecular weight polyethylene material has excellent performance, but its flame retardancy cannot meet the requirements of the coal and mining industries. This is because ultra-high molecular weight polyethylene is a flammable material and cannot meet the flame retardancy requirements. With the in-depth development of the coal mining industry, the application of ultra-high molecular weight polyethylene materials in the shipbuilding field has emerged, and the requirements are getting higher and higher, not only the requirements for flame retardancy, but also the requireme...
