Anti-explosion mining mechanical brake pad and preparation method thereof

Abstract

The invention discloses an anti-explosion mining mechanical brake pad. The brake pad is prepared from the following raw materials of a formula in percentages by weight: 10-30% of chopped glass fibers,4-10% of aramid fibers, 3-8% of frictional powder, 3-5% of petroleum coke powder, 6-10% of flake graphite, 3-8% of magnesium oxide micro-powder, 5-16% of barium sulfate, 5-10% of carbon black, 12-25%of powdered acrylonitrile-butadiene rubber, 0.5-1.5% of an anti-ageing agent TMQ, 0.2-0.5% of a vulcanization accelerator MBTS and 6-15% of high-temperature-resistant resin. The invention further discloses a preparation method of the anti-explosion mining mechanical brake pad. The anti-explosion mining mechanical brake pad is good in fire protection ability and anti-static ability, and is suitable for various mining machines.

Description

technical field

[0001] The invention relates to the field of brake pads, in particular to an explosion-proof mining mechanical brake pad and a preparation method thereof. Background technique

[0002] In the automobile braking system, the automobile brake pad is a key component of class A, and its performance is directly related to the safety and reliability of automobile operation. With the increase of the driving speed of modern automobiles, the requirements for automobile brake pads are becoming more and more stringent. Because the energy absorbed by automobile brake pads is proportional to the square of the speed, taking a car as an example, when braking at a speed of 50km / h, 100km / h and 200km / h, the heat load of braking is 282.61kJ, 1130.44 kJ and 4521.74kJ, the surface temperature of automobile brake pads is as high as 500-700°C. On the other hand, in order to ensure the stability of the car when the car is running at high speed, the wheel diameter of the car must be...
