Weather-proof high-pressure polyethylene for injection molding machining

Abstract

The invention discloses weather-proof high-pressure polyethylene for injection molding machining. The weather-proof high-pressure polyethylene for the injection molding machining is prepared from high-pressure polyethylene plastic, a fire retardant, a coupling agent, a cross-linking agent, a weather-proof agent and an antioxidant, wherein the fire retardant is zinc borate; the coupling agent is vinyltriethoxysilane; the weather-proof agent is 2-hydroxy-4-n-octyloxybenzophenone; the antioxidant is distearyl thiodipropionate. The weather-proof high-pressure polyethylene for the injection molding machining is prepared from the high-pressure polyethylene plastic, the fire retardant, the coupling agent, the cross-linking agent, the weather-proof agent and the antioxidant, and has the characteristics of uneasiness of combustion, high intensity, ageing resistance, good wear resistance, good weather-proof property and low cost.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to a weather-resistant high-pressure polyethylene for injection molding processing. Background technique [0002] Low-molecular-weight high-pressure polyethylene is generally a colorless, odorless, tasteless, non-toxic liquid, and high-molecular-weight high-pressure polyethylene is pure milky white waxy solid powder. High-pressure polyethylene has low density and low melting temperature, and more than half of it is used in film products, followed by pipes, injection molding products, and wire wrapping layers. It can also be used to make agricultural, food and industrial packaging film , Wire and cable covering and coating, synthetic paper, etc. [0003] At present, there are still great defects in high-pressure polyethylene injection molding, such as flame retardancy, strength, anti-aging, etc., and due to different processing methods, the cost is relatively high, and i...
