Abstract
The invention belongs to the technical field of modification of high polymer materials and provides a halogen-free flame-retardant high-gloss inorganic-fiber-reinforced PC / ABS material and a preparation method thereof. The halogen-free flame-retardant high-gloss inorganic-fiber-reinforced PC / ABS material is prepared from raw materials in percentage by weight as follows: 50-55% of PC, 10-20% of ABS, 0-1% of a sulphonate flame retardant, 6-12% of a phosphorus-containing flame retardant, 2.5-5.5% of a compatilizer, 5-10% of a toughening agent, 0.3-2% of a processing aid, 0.1-1% of an antioxidant, 0.1-1% of an anti-ultraviolet agent, 10-20% of inorganic fibers and 0-1% of a metal-imitating toner. According to the halogen-free, flame-retardant, high-gloss and inorganic-fiber-reinforced PC / ABS material, the aid and all the raw materials are reasonably selected and matched, the fibers and the flame retardants are added, through reasonably optimized screw combination, high-gloss, high strength, high rigidity and flame retardant properties are obtained, meanwhile, the halogen-free, flame-retardant, high-gloss and inorganic-fiber-reinforced PC / ABS material has certain impact strength and the reasonable melt flow rate, the reasonable thermal deformation temperature, the reasonable Vicat softening temperature and the like, and a high-gloss mirror effect can be realized.
Description
technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a halogen-free flame-retardant high-gloss high-glass fiber reinforced PCPC / ABS material and a preparation method thereof. Background technique [0002] Brand-new product design concepts and user needs promote the continuous innovation of new materials. The visual impact of super-large, ultra-thin and narrow-edge LCD TVs is self-evident. Traditional non-metallic materials obviously cannot meet this design demand. There is a need for a material that can simultaneously achieve high gloss, high strength, high hardness, and high impact resistance. [0003] At present, the research on high-gloss glass fiber reinforced PC / ABS alloy has made some progress. For example, the Chinese patent application with the publication number CN103044886A discloses the preparation method and application of PC / ABS alloy. The method of ABS has realized the application co...
