Background technology
Improve security performance, reduce environmental pollution and noise pollution, to increase the service life be becoming greatly of friction material development
Gesture.China's automobile brake sheet industry faces environmental protection and high performance two make the transition greatly, and environment-friendly type high performance brake block is except to expire
Outside foot high temperature decline is little, wear rate is low, stable friction factor etc. requires, also should have the environmental protection hommizations such as vibration is little, noise is low
Performance characteristics, these be all friction material formulation technology, raw material disposal technology, batch mixing technology of preparing, hot extrusion briquetting technique,
Heat treatment technics and subsequent treatment technology etc. are had higher requirement.
Brake noise is related to the comfortableness that vehicle travels, and particularly to urban environment, surrounding is caused noise
Pollute.For car and city bus, brake noise is an important performance requirement.For car disc type sheet,
Noiselessness or brake pad with low noise that frictional behaviour is good become first product.With the development of auto industry, existing to brake noise
People increasingly pay attention to, and relevant department has been proposed for standard regulation.The noise produced during general automobile brake is not to be exceeded
85dB。
For friction material, life-time service experience have shown that, causes the factor of brake noise substantially to have:
(1) coefficient of friction of friction material is the highest, is more easily generated noise, when reaching 0.45～0.5 or higher, easily produces and makes an uproar
Sound.
(2) goods material hardness height is easily generated noise.
(3) high rigidity amount of filler is easily generated noise time many.
(4) brake block is after high-temperature brake effect, and working surface forms light and hard carbonized film, also known as adamantine layer.?
Dither and corresponding noise can be produced during drag friction.
