Description
Technical field
The present invention relates to the friction material composition of automobile brake sheet, especially relate to a kind of environment-friendly type high performance friction material composition.
Background technology
Fast development along with auto industry; the safety of vehicle, environmental conservation are particularly important; people are more and more higher to the environmental-protecting performance of brake block; occur in that many novel high performance brake sheets at present on the market; but while improve braking quality; the discharge that living environment creates tremendous influence, brake noise and harmful gas can not get effectively controlling.Containing a lot of heavy metal substances, the heavy metal such as including antimony, chromium, cadmium, copper, barium, copper in the friction material that the automobile brake sheet that we use now is used.Automobile, in each brake process, just has a small amount of heavy metal dusts to discharge and accumulate and works the mischief in the environment.As cadmium compound is lodged in liver or kidney through breathing by body absorption, human kidney, liver are worked the mischief.Fish can be caused biological murder by poisoning by cupric dust after entering environment.Barium sulfate has harm to environment, can pollute air.And antimony is the least to the harm of environment, containing substantial amounts of heavy metal antimony in brake block, some brake block content can reach 4-5%, especially water body environment can be caused long-term harmful effect.As far back as 1979, antimony was put into the priority pollutants list in Environmental Protection in America portion, and within 2002, US Geological Survey finds that, due to brake block can along with the use of vehicle continued depletion, cause antimony to enter continuously in environment.Japanese researchers is it was also found that the finely ground particles in urban air just contains substantial amounts of antimony, and one of them main source is exactly brake block.
2007, in " the exhibition land used evaluation criteria of soil environment quality " of Chinese environmental protection cloth promulgated by the ministries or commissions of the Central Government, using antimony content in soil as an evaluation criterion, it is stipulated that the content of antimony must not be higher than 12mg/kg(A level) and 82mg/kg(B level).
2013, according to " The Beijing News ", twenty or thirty hollow place is occurred in that in the poplar forest of a piece of up to a hundred mu of Miyun county in Beijing's great Xin village village section, a large amount of discarded brake blocks are dumped wherein, in the tens of rice of result hollow place periphery, not even a blade of grass grows, original willow is all split the big openning of palm towards the one side in hole, as the face sprinkled by sulphuric acid.The impact that this case causes is far-reachingly; therefore must cause the attention of auto parts and components manufacturer, we must find safer on the premise of ensureing brake block performance; effective and environmental protection friction material substitutes heavy metal, to comply with mankind's requirement to environmental conservation increasingly stringent.
Summary of the invention
The friction material composition that the present invention provides that a kind of brake noise is low, content of beary metal is low, wear rate is low, thermal conduction effect is good, heat resistanceheat resistant decline performance is high, to solve that wear rate in existing automobile brake sheet is high, high-temperature brake is unstable, brake time produce low frequency noise, to technical problems such as environmental hazard are bigger.
