Antiskid high-wear-resistance self-repairing PVC film for high-speed rail ground

Abstract

The invention discloses an antiskid high-wear-resistance self-repairing PVC film for high-speed rail ground. The self-repairing PVC film is prepared from, by weight, 80-120 parts of PVC resin, 10-15 parts of modified mesoporous hollow polymer nano-microspheres, 10-20 parts of (2Z)-4-oxo-4-[3-(trifluoromethyl)-5,6-dihydro-[1,2,4]triazolo[4,3-a]pyrazin-7(8H)-yl]-1-(2,4,5-trifluorophenyl)butyl-2-ene-2-amine / triethoxysilyl propyl maleic acid / acrylonitrile copolymer, 3-5 parts of 2,4,6-tri(4-aminophenyl)-1,3,5-triazine, 5-8 parts of vermiculite, 0.5-1.5 parts of amino graphene quantum dots and 3-5parts of tributyl citrate. The invention further discloses a preparation method of the antiskid high-wear-resistance self-repairing PVC film for the high-speed rail ground. The antiskid high-wear-resistance self-repairing PVC film for the high-speed rail ground has excellent wear resistance, skid resistance, flexibility, impact resistance and buffering performance, is good in performance stabilityand long in service life and has a certain self-repairing function.

Description

technical field [0001] The invention relates to the technical field of membrane materials, in particular to a self-repairing PVC membrane for anti-skid, high wear-resisting high-speed rail ground. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, high-speed railways have sprung up like mushrooms, becoming a symbol of the development level of a modern country. It brings many conveniences to people's transportation. Because of its high speed, convenience and comfort It has good performance and has become the first choice for people to go out for transportation. High-speed rail ground is one of the important components of high-speed trains, and its performance directly affects passenger comfort and safety. Therefore, it is particularly important to develop high-speed rail ground materials with excellent performance. [0003] Ideal ground materials for high-speed rail not only need to be light in...

Problems solved by technology

However, at present, PVC film materials still have the defects that they are easy to be brittle and cracked by impact, and the ground is easily damaged by falling things, poor self-repairability, wear resistance, flexibility, cushioning performance, and comprehensive performance need to be further improved. Long-term use requirements

[0005] The Chinese invention patent with the application number 201910399409.8 discloses an environmentally friendly ground protection film, including a bottom PVC film layer and a surface PVC film layer. According to parts by weight, the raw material of the bottom PVC film layer is: 100 parts of PVC resin, 10- 20 parts, 5-8 parts of stabilizer, 2-5 parts of antioxidant, 1-3 parts of flame retardant, 5-10 parts of bottom functional additive; the raw material of surface PVC film layer is: 100 parts of PVC resin, 15 parts of plasticizer -25 parts, 6-12 parts of stabilizer, 3-6 parts of antioxidant, 1-3 parts of flame retardant, 1-2 parts of foaming agent, 5-10 parts of surface function additive, which pass through the foaming agent, bottom The addition of functional additives and surface functional additives has better impact resistance and wear resistance, and excellent anti-corrosion performance, which can be used for a long time; however, the addition of a large amount of additives will affect the overall performance and processing fluidity of the material , and these additives are easy to leak out during long-term use, have poor performance stability, and cannot be self-repaired, and have a short service life
