Embodiment 1
[0020] Weigh 25 parts of RK-150 basalt fiber, 10 parts of boron modified phenolic resin, 2 parts of friction powder, 10 parts of barium sulfate, 8 parts of calcium sulfate whisker, 5 parts of glass fiber, 3 parts of magnesium hydroxide, and 2 parts of magnesium oxide , 10 parts of steel fiber and 3 parts of nitrile rubber powder. Add the weighed RK-150 basalt fiber, friction powder, barium sulfate, glass fiber, magnesium hydroxide, magnesium oxide, steel fiber and nitrile rubber powder into the stirring device for stirring and mixing to reduce the material caused by static electricity. For the generation of agglomeration, calcium sulfate whiskers and hydrogen S3 sulfide are added as auxiliary materials during the stirring process to achieve acid-base balance, and boron-modified phenolic resin and S3 sulfide are added as binders to achieve high temperature The following bonding effect. The parts by weight of the auxiliary material hydrogen S3 sulfide and the binder S3 sulfide ...
