Abstract
The invention relates to a manufacturing method of a brake lining in the automotive industry, in particular to a method for manufacturing a brake lining with silicate whisker, which can improve the porosity of the brake lining and enhance the strength of the brake lining so that the performance of the brake lining is more stable under the conditions with high temperature and high speed. In the method, the applied bonding agents are phenolic resin, silicon modified phenolic resin and butyronitrile modified phenolic resin, the applied reinforcing materials are steel cotton fiber, aramid fiber pulp, mineral fiber, ceramic fiber, aramid fiber pulp and mineral fiber, the applied friction performance regulators comprise abrasives, lubricants and stabilizers, wherein the abrasives are aluminum oxide, iron oxide, magnesium oxide and friction powder, the lubricants are graphite, sulfide and mica, the stabilizers are silicate whisker, the applied fillers for the friction performance regulators are barium sulfate, potassium titanate and magnesium oxide. The brake lining manufactured with the formula can effectively improve the porosity and the high temperature resistance of materials.
Description
One, technical field: the present invention relates to the preparation method of the brake facing in the auto industry field, especially silicate whisker is used to prepare the method for brake facing.
Two, background technology: the essentially consist of brake facing is except binding agent, fortifying fibre, and beyond the filler,-------frictional property regulator comprises abrasive, lubricant, stablizer to also have the very important material of a class.Complete processing is as follows: batch mixing, hot-forming, grinding, spray paint, installation accessories, seal mark, packing, high temperature decline and high stability are brake facing two big vital performance requriementss, it directly affects braking safety and comfort.Though can improve decline to a certain extent by thermal ablation technology, can not address this problem, and also easy other the problem together of ablating, such as: shearing force descends, easily flake; The homogeneity of ablating; And consistency of product etc.
Three, summary of the invention: the objective of the invention is to change the internal structure of brake facing, improve the void content of brake facing by adding this special stable friction performance agent of silicate whisker, increase its intensity, thereby make brake facing when High Temperature And Velocity, performance is more stable, improves comfort level.The present invention utilizes the silicate whisker specific surface area big, high temperature resistant, with characteristics such as other materials appearance property are good, is used for the preparation of brake facing, thereby improves the void content of brake facing, improves the High Temperature And Velocity stability of brake facing.Silicate whisker is used to prepare the method for brake facing, batch mixing, hot-forming, grinding, spray paint, installation accessories; seal mark; packing; it is characterized in that: wherein used binding agent is a resol; the silicon modified phenolic resins; butyronitrile remodeling resol, its weight percent is 5-15, used strongthener is the steel wool fiber; aramid pulp; mineral fibre; ceramic fiber, aramid pulp, its weight percent of mineral fibre is 20-30; used frictional property regulator comprises abrasive; lubricant; stablizer; abrasive is an aluminium sesquioxide, ferric oxide, magnesium oxide; friction powder; lubricant is a graphite, sulfide, mica; stablizer is a silicate whisker; the frictional property regulator weight percent is 20-30, and used filler is a barium sulfate, and potassium titanate; magnesium oxide, weight percent are 30-50.The brake facing that uses this prescription to produce, can improve void content effectively, improve the high thermal resistance of material, thereby reduce the rate of decomposition of organic materials when high temperature, the effusion speed of the gas of friction surface in the time of simultaneously can reducing to fail, thus the velocity of variation of frictional coefficient is reduced in 10% when making fading rate and high speed.
Four, embodiment: silicate whisker is used to prepare the method for brake facing, batch mixing, hot-forming, grinding, spray paint, installation accessories; seal mark; packing; wherein used binding agent is a resol; the silicon modified phenolic resins; butyronitrile remodeling resol, its weight percent is 5-15, used strongthener is the steel wool fiber; aramid pulp; mineral fibre; ceramic fiber, aramid pulp, its weight percent of mineral fibre is 20-30; used frictional property regulator comprises abrasive; lubricant; stablizer; abrasive is an aluminium sesquioxide, ferric oxide, magnesium oxide; friction powder; lubricant is a graphite, sulfide, mica; stablizer is a silicate whisker; the frictional property regulator weight percent is 20-30, and used filler is a barium sulfate, and potassium titanate; magnesium oxide, weight percent are 30-50.
The problem that exists at prior art according to summary of the invention, has designed two assembly sides and according to examination
The proved recipe case is tested, and design and experimental result are as follows:
According to above formulating of recipe,, and test according to following production technique processed sample:
Batch mixing, hot-forming, grinding, spray paint, installation accessories, seal mark, packing.
(1) test-results
Common few metal formulations is when carrying out the decline program, and fading rate is up to more than 40%, and high speed performance is also very poor, is lower than 0.25, and adds few metal formulations (prescription A) of silicate whisker, and fading rate is lower than 15%, during high speed, is higher than 0.3.
Common NAO prescription is when carrying out the decline program, and fading rate is up to more than 45%, and high speed performance also presents obvious must the reduction, is difficult to reach 0.25, and adds the NAO prescription (prescription B) of silicate whisker, and fading rate is lower than 20%, during high speed, can reach 0.3.
