Problems solved by technology

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 in the use process, and the brake band of the prior art is acid-resistant, alkali-resistant, corrosion-resistant and anti-corrosion. The wear performance is poor, so the service life of the brake band of the prior art is relatively short, and the cost of use is relatively large

Abstract

The invention discloses a carbon fiber core-spun yarn reinforced brake belt, which comprises a carbon fiber core-spun yarn braided belt and a mixed rubber compound containing carbon fiber attached thereto. The innovative use of carbon fiber, and the production process is simple, and the prepared brake band has excellent performance and effect, which meets the national quality standard and international environmental protection requirements. The brake band prepared by the method of the present invention uses natural renewable fibers, the natural fiber is environmentally friendly and biodegradable, and the carbon fiber core-spun yarn reinforced brake band of the present invention significantly improves the stretching of the brake band Strength and modulus of elasticity, with excellent mechanical properties. After more than 20,000 times of braking tests, the change of front and rear braking torque does not exceed 1.5N.m, and there is no abnormal braking sound.

Description

technical field [0001] The invention relates to a brake band, in particular to a carbon fiber core-spun yarn reinforced brake band and a preparation method thereof. Background technique [0002] At present, 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-compliant materials as fillers, and anti-aging agents. The processing flow is: batching, rubber mixing, rubber molding, vulcanization, grinding, inspection, packaging. The brake bands 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 in the use process, and the brake bands of the prior art are acid-resistant, alkali-resistant, corrosion-resistant and anti-corrosion. The wear performance is relatively poor, so the service life of the brake band in the prior art is ...
