Abstract

The present invention discloses a wear-resistant anti-extrusion material for TFT-LCD, wherein the raw materials comprise, by weight, 30-36 parts of a phenol formaldehyde resin, 7-16 parts of an acrylonitrile-styrene-butadiene copolymer, 9-14 parts of gamma-methacryloxy propyl trimethoxysilane, 6-12 parts of nanometer lithium iron phosphate, 8-10 parts of nanometer silicon nitride, 7-11 parts of toluene diisocyanate, 6-10 parts of a modified composite filler, 9-13 parts of a perfluoropolyether film layer, 6-10 parts of an inorganic filler, 4-5 parts of a silane coupling agent, and 7-9 parts ofa curing agent. According to the present invention, by adding the modified composite filler to the formula of the composite material, the strength and the hardness of the final product are improved, wherein the hardness of the final product is greater than 60 HRR, such that the application range of the high-strength wear-resistant composite material for the TFT-LCD screen is substantially improved; and by mixing the resin copolymer polysiloxane polymer obtained by sequentially carrying out uniform mixing on a variety of resins and copolymerization, the curing agent and the inorganic filler, the obtained composite material has the high anti-extrusion ability, and is suitable for TFT-LCD display screens.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screens, in particular to a wear-resistant and extrusion-resistant material for TFT-LCD. Background technique [0002] Composite materials are composed of two or more organic materials with different properties, through physical or chemical methods, macroscopically composed materials with new properties. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. [0003] At present, the comprehensive properties of composite materials for TFT-LCD screens on the market are various. The strength and hardness of materials are necessary conditions to limit the application range and application field of materials. Organic composite materials generally use resin and rubber as raw materials, and their ow...
