Special brake pad for resisting sand and gravel while passing through water tank

Abstract

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.

Description

【Technical field】 [0001] The invention relates to the field of brake pad manufacturing, in particular to a special brake pad for anti-gravel in water tanks. 【Background technique】 [0002] Purpose, with the improvement of society’s environmental requirements, engineering vehicles must pass through the water tank when leaving the construction site, and then go on the road after cleaning. Due to the limited conditions of the construction site, the muddy water in the water tank is basically not changed, and the water depth is submerged for more than half of the wheels. The muddy water enters the in the brake drum. Such working conditions put forward higher requirements for the brake pads, which must be resistant to high temperature, water, and sand and gravel. Now the brake pads on the market are generally only about ten days long after they pass through the water tank under high temperature. It mainly solves the problem that the existing brake pads should not only be resistan...

Problems solved by technology

Such working conditions put forward higher requirements for the brake pads, which must be resistant to high temperature, water, and sand and gravel. Now the brake pads on the market are generally only about ten days long after they pass through the water tank under high temperature. It mainly solves the problems that the existing brake pads need to be resistant to water and high temperature when passing through the water tank, and also reduce the wear of the brake pads by gravel.
