Background technology
Brake system of car refers to, applies certain power to some parts of automobile (mainly wheel), so as to be carried out to it
A series of special arrangements of a certain degree of forced brake.Brake system of car is to influence the critical system of vehicle safety, and
The stability and reliability of brakes are then directly determined by the combination property of friction plate (especially brake block)；Conventional stops
Car piece is divided into：1st, asbestos type, because asbestos fibre has high intensity and resistant to elevated temperatures feature, therefore meets brake block and clutch
The requirement of device disk, while having the tensile energy of fiber and the hardness and wearability of advanced metal material；2nd, semipermanent mold, mainly
It is to adapt to higher as fiber and the big mixture of important coefficient of friction, major advantage is reinforced using coarse steel wool
At a temperature of normal work；3rd, without asbestos organic type, mainly with glass fibre, aromatic polyester fiber and other fiber conducts
Reinforcement material, its performance depends primarily on the type and other mixtures of fiber.Wherein semimetal or be China without cotton organic type
One of asbestos-free friction material of main popularization and application.But semi-metallic brake pad corrosion under moisture effect is serious, is made an uproar during brake
Sound is higher, and vibration is larger, there is certain damage to brake disc, and most semimetals or micro-metal brake pad are in use
The dust easily produced, these dust adsorptions are on wheel hub, due to being difficult to clean, and influenceed for a long time by it, easily cause wheel hub rotten
Erosion；It is not high to there is combination property in current automobile brake friction plate, the problem of various performances can not be taken into account, such as some strength and toughness
It is unstable that rubbing in deficiency, brake temperature-rise period examines coefficient, while there is skidding, brake locking and falls grey serious, is formulated in addition
The deficiency of system so that frictional interface does not lubricate damping layer so that product brakes shakiness in use, hinders disk, is reduced
Service life, generation makes one the presence of the defects such as insufferable noise.
Such as Application No.：201310219952.8 Chinese patent disclose a kind of friction material, automobile friction, one
Kind of friction material, by weight percentage consisting of：Bonding agent 8%~15%, reinforcing agent 24%~33%, increasing grinding agent 7.2-
9.8%th, antifriction lubricant 16.5%~20%, elastomeric toughening agent 4.5%~6.5%, inserts 24.8%~30.6%；It is a kind of
It is prepared by automobile friction, any one friction material of usage right requirement 1~8；Friction material disclosed in this application is carbon fiber
Base ceramic formula system, makes to prepare that friction disc brake is steady, dust is few, because hardness is moderate using the application friction material, heat
Small, the high temperature restorability that fails is good, but this application does not have in terms of reducing noise and reducing the damage to automobile friction that rubs
Specific solution formula or method are provided, and production cost is also of a relatively high, is not suitable for large-scale promotion.
For another example Application No.：201610917394.6 Chinese patent disclose a kind of ceramic brake, by following components
It is prepared from：Butadiene acrylonitrile rubber 1~5kg of powder, noise reduction 5~10kg of powder, 6~10kg of resin, 3~8kg of whisker, 3~8kg of brass fiber,
1~4kg of chopped fiber, 1~5kg of Frication powder, 1~4kg of long fibre, 8~16kg of ceramic fibre, 3~8kg of high temperature barium, crystalline flake graphite
(- 195) 4~9kg, 0.5~3kg of iron, oil 2~6kg of coke, 8~13kg of ceramic additive, 8~13kg of abrasion-resistant powder, aramid fiber
0.5~3kg, 1~4kg of wood-fibred, ceramics increase in 2~6kg of grinding agent, 1~4kg of antimony trisulfide, 3~8kg of stabilizer, this technical scheme
Disclosed brake block, which has, does not injure good frictional disk, brakeless noise, temperature tolerance, service life length, braking comfortably, and cost is low
The features such as, but the ceramic brake intensity in this application is relatively low, and abrasion resistance properties are slightly worse.
The content of the invention
