Abstract

The invention discloses a scratch-resistant injection molding material. The scratch-resistant injection molding material comprises the following components in percentage by mass: 42-50 percent of high polymer polypropylene, 25-30 percent of wood flour, 4-6 percent of epoxy butyl oleate, 2-5 percent of magnesium oxide, 3-7 percent of turpentine, 1-3 percent of flexibilizer and 18-22 percent of scratch-resistant agent. The parts manufactured by the injection molding material have high scratch resistance, the overall attractive appearance of the parts is well maintained, and the probability that the parts are frequently replaced by users due to scratch is reduced, so that the cost investment is reduced.

Description

technical field [0001] The invention relates to an injection molding material, in particular to an injection molding material with a scratch-resistant function. Background technique [0002] With the development of technology and the change of people's ideas, many non-metal parts appear in auto parts. Among them, the dominant material of non-metal parts is plastic parts, which are easy to process, easy to install and light to use, so they are more and more favored by the automobile industry. The use of plastic parts is an inevitable requirement for the future development of automobiles. [0003] The so-called injection molding (injection molding) refers to the method of injecting the heated and melted material into the mold, cooling and solidifying to obtain the molded product. The specific process is that the granular or powdery plastic is fed from the hopper of the injection molding machine into the heated barrel, heated and plasticized into a molten state, and then injec...
