The invention discloses a special brake pad for resisting sand and gravel while passing through a water tank. The break pad is prepared from the following components in parts by mass: 25-40 parts of RK-150 basalt fiber, 10-14 parts of boron modified phenolic resin, 2-5 parts of frictional powder, 5-15 parts of barium sulfate powder, 5-15 parts of calcium sulfate whisker, 3-10 parts of glass fiber,3-5 parts of magnesium hydroxide powder, 2-8 parts of antimony sulfide, 10-15 parts of steel fiber, 8-20 parts of foam iron powder and 3-5 parts of nitrile-butadiene rubber powder. The brake pad hasthe beneficial effects that compared with a traditional brake pad, the brake pad uses the boron modified resin, the antimony sulfide, magnesium hydroxide and other materials as an adhesive and forms anon-polar adhesive section with relatively high hardness on the surface of the brake pad at the high temperature, thus the influence of water and the sand and gravel on the brake pad is effectively avoided when the brake pad passes through the water tank at the high temperature, and the effect of prolonging the service life of the brake pad is achieved.
