Embodiment Construction

[0039] Green sandalwood fiber reinforced environment-friendly automobile brake pads use nitrile rubber modified phenolic resin as binder, green sandalwood fiber, meta-aramid fiber, ceramic fiber as reinforcing material, and silicon carbide abrasive material, soft Foam iron powder, flake aluminum powder, and carbon black are used as friction performance regulators to improve and enhance the friction performance of brake pads. The brake pad has good toughness, high strength and good stability, and its main performance indicators have reached the relevant national standards. It is a new generation of environmentally friendly automobile brake pads.

[0040]The optimum formula ratio that the present invention obtains through repeated tests is:

[0041] serial number name Proportion 1 Green Sandalwood Fiber 10% 2 meta-aramid fiber 4% 3 Ceramic fiber 14% 4 Nitrile rubber modified phenolic resin 11% 5 A silane coupling agent 3.5% 6 ...

Abstract

The invention discloses a pteroceltis tatarinowii bark fiber reinforced environment-friendly brake pad. Nitrile butadiene rubber modified phenolic resin is used as an adhesion agent; pteroceltis tatarinowii bark fibers, meta-aramid fibers and ceramic fibers are used as a reinforcing material; and a silicon carbide abrasion resistance improving material, soft porous iron powder, squama aluminum powder and carbon black are added and used as a friction performance conditioning agent, so that the friction performance of the brake pad is improved. The main performance index of the brake pad meets the national related standards, and the brake pad is a new generation environment-friendly brake pad. According to the pteroceltis tatarinowii bark fiber reinforced environment-friendly brake pad, an optimal formula system and an optimal processing technology are obtained through multiple orthogonal tests, and the prepared pteroceltis tatarinowii bark fiber reinforced environment-friendly brake pad has the advantages of being high in product strength, stable in friction stability, light in weight, low in cost, environmentally friendly, free of pollution and the like.

Description

technical field [0001] The invention relates to a brake pad for automobile braking, in particular to an environment-friendly brake pad reinforced with cedarwood fiber. Background technique [0002] With the development of heavy-duty and high-speed automobiles, people have higher and higher requirements for the performance of friction and braking materials for automobiles. In addition to high speed, heavy load, safety and reliability, comfortable ride, and convenient operation, etc., green and environmentally friendly friction materials with less pollution, low noise, and no or less friction dust have been developed. Controlling environmental pollution has gradually become the focus of people's driving and the first requirement of life. [0003] After years of painstaking research on various natural fibers, it is found that using natural fibers as reinforcing fibers to prepare friction materials can effectively reduce noise, prolong the service life of brake discs, and produ...
