Abstract

The invention discloses a brake band based on modified carbon fiber and a preparation method thereof. The brake band is prepared from the following raw materials in parts by weight: 35 to 45 parts of nitrile rubber, 15 to 25 parts of butadiene styrene rubber, 20 to 30 parts of modified carbon fiber, 3 to 5 parts of rubber accelerator, 2 to 4 parts of vulcanizing agent, 2 to 4 parts of 4020 anti-aging agent, 6 to 8 parts of graphite, 1 to 3 parts of nano kieselguhr, 2 to 4 parts of zinc stearate, 1 to 3 parts of nano titanium dioxide and 1 to 3 parts of nano silicon dioxide. The preparation method comprises the following steps: mixing the raw materials in a blender mixer so as to prepare a compression molding material, putting the compression molding material in a mold for compression molding, preparing blank through vulcanizing, cutting the blank, and preparing the brake band, wherein for compression molding, the pressure is 100 to 300 kg / cm<2>, the temperature is 100 to 200 DEG C, and the time is 5 to 15 minutes; for vulcanizing, the temperature is 120 to 160 DEG C, and the time is 0.5 to 1.5 hours. The brake band provided by the invention uses the modified carbon fiber to replace asbestos, a human body cannot be damaged, and the brake band has a good brake effect.

Description

technical field [0001] The invention relates to a brake band, in particular to a modified carbon fiber-based brake band and a preparation method thereof. Background technique [0002] The raw materials for making brake pads include the following components: nitrile rubber, DM accelerator, zinc oxide and stearic acid as active agents, sulfur as vulcanizing agent, asbestos composite material as filler, and 4010 anti-aging agent. The processing flow is: batching-rubber mixing-rubber molding-vulcanization-grinding-inspection-packaging. The brake band prepared by this technology can basically meet the daily requirements, but because the main component of the filler is asbestos, it causes noise and environmental pollution during use. [0003] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals alon...
