Abstract

The invention discloses a preparation method of a friction material with good running-in performance. The friction material comprises the following components: 16-18 parts by weight of a butadiene-acrylonitrile modified phenol-formaldehyde resin, 2-3 parts by weight of an aramid fiber, 3-5 parts by weight of a copper fiber, 7-9 parts by weight of a vermiculite fiber, 5-7 parts by weight of a calcium carbonate crystal whisker, 3-5 parts by weight of a 60-150 mesh silicon dioxide, 3-5 parts by weight of a 200-320 mesh aluminium oxide, 2-4 parts by weight of a colloid supramoly, 6-8 parts by weight of a 120 mesh scale graphite, 3-5 parts by weight of a 200 mesh antimony sulfide powder, and 10-12 parts by weight of a 200 mesh light calcium carbonate. The preparation method comprises the following steps: preparing the raw materials, feeding the raw materials except the scale graphite and the colloid supramoly into a mixer to be mixed for about 4-6 hours, feeding the two kinds of the scale graphite and the colloid supramoly into the mixer to be mixed with the above mixture for 3-5 hours; hot compacting the mixture under a compacting pressure of about 26-28MPa at a temperature of about 170-180 DEG C and at a compacting speed of about 0.1-0.2 mm / second, and performing exhaust in the middle; and finally controlling the mixture at a constant temperature of 160-180 DEG C for about 8-10 hours.

Description

technical field [0001] The invention relates to the field of friction materials, in particular to a preparation method of a friction material with good running-in performance. Background technique [0002] Friction materials are usually composed of five types of materials: binders, reinforcing fibers, abrasives, lubricating materials and fillers. Its functions are as follows: [0003] Binder: Bonds powder materials such as reinforcing fibers, abrasives, lubricating materials and fillers together. Modified phenolic resins are generally used. Commonly used are: cashew nut shell oil modified phenolic resin, nitrile rubber modified phenolic resin, aromatic hydrocarbon modified phenolic resin and various imported high temperature resins. [0004] Reinforcing fiber: plays a key role in the friction process of friction materials, can play a reinforcing role and improve friction and wear performance characteristics. Commonly used reinforcing fibers are: asbestos fiber, steel fib...
