Embodiment Construction

[0018] The friction material of the present invention includes resin, steel fiber, aramid fiber, coconut carbon fiber and petroleum coke, and the formula of its parts is resin: steel brazing fiber: aramid fiber: coconut carbon fiber: petroleum coke=5-15: 15-40: 1-8:5-35:3-18, made by mixing with a mixer.

[0019] The manufacturing method of the brake pad of the present invention is as follows: resin: steel brazing fiber: aramid fiber: coconut carbon fiber: petroleum coke = 5-15: 15-40: 1-8: 5-35: 3-18 parts formula The aramid fiber and coconut carbon fiber are mixed evenly in the high-speed mixer, and then the steel brazing fiber is put into the high-speed mixer and stirred together with the evenly mixed aramid fiber and coconut carbon fiber mixture. Stir petroleum coke, stir evenly, then add resin to stir, stir evenly, take out, select different brake pad molds according to the occasion of the brake pad, put the friction material in the brake pad mold to brake the brake pads....

Abstract

The invention discloses a method for manufacturing a brake pad through an environment-friendly coconut charcoal fiber composite friction material. The method includes the steps that aramid fibers and coconut charcoal fibers which are in the formulation with 5-15 parts of resin, 15-40 parts of steel fibers, 1-8 parts of aramid fibers, 5-35 parts of coconut charcoal fibers and 3-18 parts of petroleum coke are evenly stirred in a high-speed stirrer; then, the steel fibers are put into the high-speed stirrer to be stirred with the mixture of the aramid fibers and the coconut charcoal fibers which are evenly mixed; after even stirring is conducted and the temperature is lowered to the room temperature, the petroleum coke is added to be stirred; after even stirring is conducted, the resin is added to be stirred; after even stirring is conducted, the mixture is taken out; different brake pad molds are selected according to the occasions on which the brake pad is used; the prepared friction material is put into a brake pad mold, and the brake pad mold is put into a mold press to be subjected to mold pressing, wherein the mold pressing pressure ranges from 15 Mpa to 16 Mpa, the temperature ranges from 150 DEG C to 160 DEG C, the conditions are maintained for 12-15 minutes, pressure is relieved, and heating is stopped; and the brake pad mold is taken out, and the brake pad is poured out and corrected and polished on a grinding machine.

Description

technical field [0001] The invention relates to an environment-friendly coconut carbon fiber composite friction material, a brake pad and a production method for the brake pad. Through the optimized combination of formula materials and the optimization of a production process test scheme, barium sulfate and copper sulfate which are not harmful to the human body and the environment are used. The formulation of fiber, antimony metal and graphite materials produces high-performance, non-polluting, clean and environmentally friendly friction materials and brake pads. Background technique [0002] The coefficient of friction is the most important performance index of any friction material, and it is related to the braking ability of the brake pads. The currently used brake pads generate heat due to friction during the braking process, the working temperature increases, the friction coefficient decreases, and the braking effect is reduced. The friction coefficient is too high and...
