These requirements are added on the basis of high performance. At present, there are relatively few researches on the green and environmental protection of brake pad friction materials. A green brake friction with no pollution, reliable performance and moderate cost has been developed. Materials are an inevitable requirement to adapt to the development of the times

Embodiment 1
[0027] A coconut fiber brake pad, comprising the following components in percentage by weight: 20 parts of resin, 24 parts of barite, 15 parts of aluminum oxide, 7 parts of graphite, 5 parts of rubber powder, 9 parts of coconut fiber, and 10 parts of lanthanum oxide , 10 parts of ceramic fiber.
[0028] The preparation method of described coir fiber brake pad is as follows:
[0029] (1) Drying of raw materials: Dry phenolic resin at 60°C for half an hour, coconut fiber at 100°C for one and a half hours, lanthanum oxide at 220°C for two hours, rubber powder at 60°C for half an hour Hours, other components were dried at 110°C for one hour.
[0030] (2) Cutting: Use a fiber cutter to cut the coconut shell fiber to obtain coconut shell fiber with a suitable length.
[0031] (3) Mixing: Mix the dried raw materials according to the experimental design formula and put them into a BL25C33 mixer with multiple sets of high-speed rotary knives for 1-2 minutes to obtain a uniform powder...

Abstract
The invention discloses a coconut fiberbrake pad and a preparation method thereof. The coconut shell fiberbrake pad is prepared from the following raw materials of, by weight, 19-25 parts of resin, 5-10 parts of coconut fibers, 5-10 parts of ceramic fibers, 20-30 parts of barite, 15-20 parts of aluminum oxide, 5-15 parts of graphite, 10-15 parts of lanthanumoxide and 3-5 parts of rubber powder. The integrality of the brake pad is enhanced through the high-strength coconut fibers, the friction coefficient of the brake pad is increased, the wear rate is reduced, meanwhile the cost of the brake pad can be reduced, and by reusing the coconut fiber, the problem that the natural fiber demand of an existing brake pad is short is effectively solved, and a new way for treating the coconut fiber is also added.
Description
technical field [0001] The invention belongs to the field of automobile brake materials, and relates to a coconut shell fiber brake pad and a preparation method thereof. Background technique [0002] At present, the brake pad material is gradually mature, and has good performance in terms of tribological properties and mechanical properties. However, with the advancement of technology, people have found that the current brake pad materials contain various metal components such as copperpowder, and these components will cause pollution to the atmosphere and rivers to varying degrees. This kind of heavy metalpollution makes people realize the importance of sustainable development, so the requirements for green, no noise, and high-efficiency utilization are put forward for synthetic brake pads. These requirements are added on the basis of high performance. At present, there are relatively few researches on the green and environmental protection of brake pad friction material...
