Corrosion resistant brake block and machining method thereof

Abstract

The invention relates to the field of car machines, and provides a corrosion resistant brake block. The corrosion resistant brake block comprises the following raw materials including aluminum fibers,glass fibers, nitrile butadiene rubber powder, tire powder, cashew nut shell oil friction powder, Tung oil modified phenolic resin, red copper fibers, white zi stone powder, fluorite powder, apocynumvenetum fibers, iron oxide green, barite, petroleum coke, graphite, potassium hexatitanate whiskers, ceramic hollow microspheres, barium sulfate, molybdenum disulfide and a soft magnetic material. The invention further provides a machining method of the corrosion resistant brake block. The corrosion resistant brake block and the machining method have the advantages that in the formula research process, a large quantity of experiments show that multiple ingredients are reasonably matched, it is guaranteed that advantages of all materials are sufficiently played in the materials, shortcomings about performance of the raw materials can be offset mutually, and the better performance is achieved through mutual matching. In the using process, the high and stable friction coefficient and the lowwear rate are achieved, and abrasion is not prone to being borne.

Description

technical field [0001] The invention relates to the field of automobile machinery, in particular to a corrosion-resistant brake pad and a processing method thereof. Background technique [0002] Brake pads are also called brake pads. In the braking system of a car, the brake pads are the most critical safety parts, and the brake pads play a decisive role in the quality of all braking effects. [0003] Earlier automobile brake pads were asbestos-type brake pads, but asbestos has been confirmed by the medical profession to be a carcinogen. Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and the needle-like fibers can easily enter the lungs and stay there, causing irritation, which can eventually lead to the occurrence of lung cancer; in addition, asbestos-type There is another important problem with brake pads: because asbestos is adiabatic, its thermal conductivity is particularly poor.

Problems solved by technology

Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and the needle-like fibers can easily enter the lungs and stay there, causing irritation, which can eventually lead to the occurrence of lung cancer; in addition, asbestos-type There is another important problem with brake pads: because asbestos is adiabatic, its thermal conductivity is particularly poor. After repeated use, the brake will cause heat to accumulate in the brake pads. After the brake pads become hot, their braking performance will decrease. Changes, to produce the same friction and braking force will require more times to step on the brakes, if the brake pads reach a certain temperature, it will cause brake failure

However, the formula design of some semi-metallic brake pads often has a certain degree of blindness, which causes some inherent disadvantages of semi-metallic brake pads to be magnified, such as greater damage to the brake drum or brake disc, and in the long-term use. Serious corrosion during the process, etc.
