Background technology
In today of auto industry fast development, safe and environment-friendly particularly important, the new demand to automotive brake pads of vehicle
It is continuously improved.Automotive brake pads by bearing extraneous pressure, generates friction, vehicle is made to achieve the purpose that deceleration at work.Cause
This, the wear-resisting and heat resistance of the material of brake block is particularly significant.In addition, used in the automotive brake pads that we use now
Contain the heavy metals such as many heavy metal substances, including antimony, chromium, cadmium, copper, barium, copper in friction material.Automobile is in each brake process
In, just there are a small amount of heavy metal dusts to discharge and accumulate and causes damages in the environment.If barium sulfate is harmful to environment, to air
It can pollute.Can fish be caused with biological murder by poisoning since cupric dust enters after environment, therefore the U.S. starts limit copper
It uses, part state government provides that from 1 day January in 2021, the copper that Automotive Friction Material contains must not exceed the 5% of total weight.Cadmium
Compound is lodged in by body absorption in liver or kidney through breathing, and is caused damages to human kidney, liver.And antimony is to the danger of environment
Evil is not also small, and a large amount of heavy metal antimony is contained in brake block, and content can reach 4-5%, especially can cause to grow to water body environment
Phase harmful effect.Early in 1979, antimony was put into the priority pollutants list in Environmental Protection in America portion, United States Geological in 2002
Investigation bureau finds that, due to brake block can with the use of vehicle continued depletion, cause antimony continuously to enter in environment.
, it was also found that the finely ground particles in urban air just contain a large amount of antimony, one of main source is exactly Japanese researchers
Brake block.
2007, what Chinese environmental protection portion promulgated《Exhibition land used evaluation criteria of soil environment quality》In, antimony in soil
In content as an evaluation criterion, it is specified that the content of antimony must not be higher than 12mg/kg（A grades）And 82mg/kg（B grades）.
2013, according to《The Beijing News》Report occur in a piece of up to a hundred mu of the poplar forest of the village great Xin village of Miyun county in Beijing section
Twenty or thirty hollow place is largely discarded brake block and is dumped wherein, and as a result not even a blade of grass grows in the tens of rice in hollow place periphery, original willow
It all splits the big openning of palm towards the one side in hole, as the face sprinkled by sulfuric acid.It influences to be far-reaching caused by this case
Ground, therefore the attention of auto parts and components manufacturer must be caused, we must find under the premise of ensureing to brake piece performance
It is safer, heavy metal effectively is substituted with the friction material of environmental protection, to comply with mankind's requirement increasingly strict to environmental protection.
