High weathering resistance fire retardation ABS composite material

Abstract

The invention relates to a high weathering resistance fire retardation ABS composite material, which comprises the following raw materials, by mass, 70-85 parts of a ABS resin material, 5-10 parts of PEI, 0.5-1 part of polytetrafluoroethylene, 0.5-1 part of a lubricant, 0.1-0.5 part of an ultraviolet absorber, 0.4-0.6 part of an antioxidant, and 10-20 parts of a fire retardation agent, wherein the ABS resin is an acrylonitrile-butadiene-styrene copolymer, the lubricant is calcium stearate or tristearin, the ultraviolet absorbent is 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-n-octyloxy benzophenone or 2-(2'-hydroxy-3',5'-di-tert phenyl)-5-benzotriazole chloride, and the fire retardation agent is one or two selected from triphenyl phosphate and ultrafine magnesium hydroxide. According to the present invention, PEI and ABS are compounded, and then a fire retardation agent, polytetrafluoroethylene, an ultraviolet absorber and an antioxidant are added so as to improve mechanical property, weathering resistance and fire retardation of the material.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a highly weather-resistant flame-retardant ABS composite material. Background technique [0002] ABS resin is a thermoplastic engineering plastic with a wide range of uses. It has excellent mechanical properties, excellent impact strength, can be used at extremely low temperatures, has excellent wear resistance, good dimensional stability, and oil resistance. Widely used in automotive industry, electronic appliances, instrumentation, textile and construction and other fields. However, ABS resin has a low heat distortion temperature, is flammable, has poor weather resistance and its mechanical properties are easily affected by temperature, so it is particularly important to modify it to further improve its performance. [0003] At present, the existing technology mainly modifies the flame retardant performance of ABS resin by adding flame retardants, but the...

Problems solved by technology

However, ABS resin has a low heat distortion temperature, is flammable, has poor weather resistance and its mechanical properties are easily affected by temperature, so it is particularly important to modify it to further improve its performance.

[0003] At present, the existing technology mainly modifies the flame retardant performance of ABS resin by adding flame retardants, but the use of halogen flame retardants will have adverse effects on the environment and human body during combustion; methods such as adding antioxidants or different resins are used. Its weather resistance is improved, but its mechanical properties have not been effectively improved while the weather resistance is improved.
