Problems solved by technology

However, during the processing of brake pads, 15% of grinding dust will be generated due to the grinding, grooving, chamfering and other processes of the working surface, which will not only cause great environmental pollution, but also waste valuable material resources.

Embodiment Construction

[0014] First weigh 1.5kg of phenolic resin, 1.0kg of nitrile rubber powder, 5.5kg of steel fiber, 1.75kg of -195 graphite, 1.5kg of artificial graphite, Al 2 o 3 0.125kg, BaSO 4 3.75kg, 8.125kg of grinding dust, poured into the plow mixer and stirred evenly for 5 minutes, made into a friction material containing grinding dust, then put it into the mold and pressed it for 8-10 minutes, and kept the unit pressure at 15-20Mpa After pressing and forming, take out the brake pads for heat treatment. The heat treatment procedure is 140°C for 1h, 165°C for 2h, 180°C for 2h, 195°C for 1h, and then cooled to room temperature, according to GB5763-1998 and SAE J661 standard procedures Constant speed and CHASE test.

Abstract

A recycling method of abrasive dust in the brake plate preparation process is provided. The brake plate is compounded by 5 percent to 10 percent of adhesives, 10 percent to 30 percent of reinforced material, 10 percent to 35 percent of friction performance regulator, 8 percent to 25 percent of stuffing and 25 percent to 65 percent of grinding dust material on quality. Under the unit pressure of 15 to 20MPa, the prepared and weighed friction material is poured into a plow harrow mixer to be evenly stirred for 5 minutes and then put into a mould to be suppressed for 8 to 10 minutes. The method has the following heat treatment procedures: keeping for 1 hour at 140 degrees centigrade, keeping for 2 hours at 165 degrees centigrade, keeping for 2 hours at 180 degrees centigrade, keeping for 1 hour at 195 degrees centigrade and then cooling to normal temperature. The invention recycles the waste reasonably, avoiding environmental pollution and obviously improving the friction coefficient stability and consistency of the product. The friction coefficient fluctuation is reduced 15 percent and the heat fading is small. The stability of the friction performance is improved more than 15 percent and the abrasion wear is reduced more than 20 percent. At the same time, the manufacture cost is reduced 15 percent and the economic benefit is also improved.

Description

Technical field: [0001] The invention relates to a method for recycling and reusing grinding dust generated during brake pad processing. Background technique: [0002] Brake pads (brake pads) are active safety parts for key components of the automobile running system. Its function is to ensure that the brakes are sensitive, safe and reliable when the vehicle brakes or decelerates. It is not only used in the braking system of the automobile running part, but its friction material is also suitable for railway locomotives, oil drilling, aerospace and other fields. The industry has a high degree of correlation and has broad market application space and industrialization prospects. Brake pads, as friction materials, use mutual friction to absorb kinetic energy and convert kinetic energy into heat energy. Therefore, when brake pads brake, they will cause a significant temperature rise. Therefore, the raw materials used in the brake pad formula must be Considering the friction and...
