Problems solved by technology

At present, due to environmental protection requirements, cars need to pass water when entering and leaving the construction site, which puts forward higher requirements for the brake pads of high-horsepower engineering vehicles. However, after the existing ordinary brake pads are subjected to high temperature and water, the service life is usually only 1 month. about a month
In addition, the performance of new replacement reinforcing fibers used in brake pads has certain limitations: mineral fibers are hard and brittle, low in strength, and poor in wear resistance; Unstable, poor wear resistance; aramid has good affinity, high strength but low cost performance

Abstract

The invention discloses a water-passing durable type brake pad and a preparation method thereof. The water-passing durable type brake pad comprises raw materials of RK-150 basalt fibers, boron-modified phenolic resin, friction powder, barium sulfate, calcium sulfate whiskers, glass fibers, magnesium hydroxide, magnesium oxide, steel fibers and nitrile butadiene rubber. Through mixing, die-filling,pressurized heating, pulling out of a die, heat treatment, cutting, polishing and drilling, the prepared brake pad is more durable and high in strength, has the relatively stable friction coefficientand is not liable to crack, and the service life of the brake pad is not less than five months.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to the technical field of a preparation method of a water-durable brake pad. Background technique [0002] Widely used high-horsepower engineering vehicles have high horsepower, large load and fast speed. At present, due to environmental protection requirements, cars need to pass water when entering and leaving the construction site, which puts forward higher requirements for the brake pads of high-horsepower engineering vehicles. However, after the existing ordinary brake pads are subjected to high temperature and water, the service life is usually only 1 month. month or so. In addition, the performance of new replacement reinforcing fibers used in brake pads has certain limitations: mineral fibers are hard and brittle, low in strength, and poor in wear resistance; Unstable, poor wear resistance; aramid has good affinity, high strength but low cost performance.
