Abstract
The invention relates to the technical field of high polymer materials, and particularly relates to a high-brightness high-wear-resistance glass fiber reinforced modified polypropylene composite material and a preparation method thereof. According to the high-brightness high-wear-resistance glass fiber reinforced modified polypropylene composite material, ceramic micropowder or silicon dioxide iscompounded with glass fibers and silicone master batch for modifying polypropylene, so that the polypropylene composite material has good wear resistance and mechanical performance. According to the high-brightness high-wear-resistance glass fiber reinforced modified polypropylene composite material, a modified ethylene bis-fatty acid amide product is used as an auxiliary agent for preventing theglass fibers from being exposed, so that a fiber floating phenomenon on the surface of the glass fiber reinforced composite material is improved. Meanwhile, the length and the addition proportion of the glass fibers are controlled, so that the composite material has good surface appearance smoothness. The high-brightness high-wear-resistance glass fiber reinforced modified polypropylene compositematerial provided by the invention can replace polyformaldehyde and modified nylon materials to a certain extent to be used for preparing products such as pulleys, gears, trundles and the like in theindustrial field and the field of toys for children.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high brightness and high wear resistance glass fiber reinforced modified polypropylene composite material and a preparation method thereof. Background technique [0002] The production cost of polypropylene resin raw materials is low, the comprehensive mechanical properties are good, the density is small, the injection molding processing window is wide, the heat resistance temperature is high, and the electrical insulation and chemical stability to acid and alkali are also very good, so it is widely used in industry and children. field of toys. However, polypropylene materials also have their shortcomings, that is, insufficient wear resistance, easy to be scratched, or even lost by abrasion, as well as insufficient mechanical strength and low modulus, which limit the use of polypropylene materials in some wear-resistant, Applications in products requiring high streng...
