Description
Technical field
The invention belongs to braking brake block of Motor vehicles and preparation method thereof, relate in particular to a kind of nano material automobile brake sheet.
Automobile is being brought into play more and more important effect as the Modern Traffic transportation means in national economy and people's social life.Automobile industry obtains fast development as China's new industry industry over past ten years, along with the develop rapidly of car industry, a series of new requirements and new problem have also occurred simultaneously, embodies a concentrated reflection of to be security, comfortableness, weather resistance.And the brake portion of this three property and automobile is closely-related.The component of brake portion are many, and automobile brake sheet is wherein very important a kind of part.Its performance how, directly determining above-mentioned three property.Existing brake facing is divided by the material of its use two kinds, and a kind of is asbestos abrasives brake facing, and a kind of is the semimetal friction material brake facing, and asbestos brake lining easily causes environmental pollution to be eliminated.Semi-metallic brake pad easily get rusty and the noise that brakes big.
Summary of the invention
The objective of the invention is to overcome the shortcoming of present brake facing, a kind of non-environmental-pollution is provided, good endurance, the brake facing of the good and safety and comfort of heat resistance, another object of the present invention provides a kind of preparation method of brake facing.
The present invention is that following technical scheme realizes: a kind of brake facing is characterized in that: the weight part of each component is:

Increase the agent 10-12 part of rubbing
It is described that to increase the agent that rubs be rice-pudding diamond spar or magnesium oxide.
Described Mierocrystalline cellulose is steel fiber, alkali free glass fibre, Na Kaifu fiber or ceramic fiber.
The granularity of described various raw materials≤200 orders.
The preparation method of described brake facing is characterized in that:
(1) takes by weighing various raw material for standby by prescription;
(2) will stir churning time 5-6 minute in the various raw materials input stirrers;
(3) compression molding: coating release agent in the mould of preheating, mixture to be poured into carry out the molded processing of molding heat in the mould, its hot pressing temperature is 150-160 ℃, hot pressing time is 8-20 minute;
(4) under 150-175 ℃ of temperature, solidify and stablize about 4 hours;
(5) brake facing after solidifying is carried out grooving, chamfering, ground finish arrangement;
(6) electrostatic painting;
(7) thermal treatment gets the finished product brake facing.
Advantage of the present invention is: above-mentioned brake facing fine heat-resisting performance, and wear rate is low, and flexility is good, and is comfortable.
