Problems solved by technology
[0002] At present, the domestic brake pads used in urban buses in the prior art are hard brake pads. High-quality brake pads, because phenolic resin and asbestos are harmful substances that can cause cancer, the smell produced by the brake pads during braking will cause great harm to the human body; iron red and metal powder have higher hardness. The hardness of the produced brake pads is high. When the vehicle brakes, it will generate a lot of noise, scratch the wheel hub, and skid in rainy and snowy days.
Using phenolic resin as adhesive, hard brake pads made of asbestos, iron red, iron powder, and metal powder still have problems such as high density, poor affinity with the opposite wheel, and serious pollution to the environment.

Embodiment
[0016] The rubber soft brake pad for automobiles of the present invention is made of asbestos-free, phenolic resin-free, and metal-powder-free soft materials as a whole. According to the percentage by weight, 3% of zinc oxide, 10% of graphite, and 15% of carbon black are used. , oleic acid 2%, copper wire 2%, magnesium oxide 2%, coumaron 4%, rubber 15%, barium sulfate 25%, clay 20% and M accelerator 2% as raw materials, rubber as binder, The raw materials are put into a mixer and stirred evenly to make a mixture, and the mixture is hot-pressed through a mold at a hot-pressing temperature of 150°C for 10 minutes to form a mold.
[0017] See figure 1 , figure 2 , the shape of soft rubber brake pads for automobiles is arc-shaped, with a friction body 1 and an installation process hole 2; the friction body 1 is in the shape of an arc, and its arc radius R is 150cm; the thickness h of the friction body 1 is 15cm , the four installation process holes are evenly arranged at the fo...

Abstract
The invention relates to a rubber soft brake pad for an automobile. The rubber soft brake pad is characterized in that zinc oxide, graphite, carbon black, oleic acid, copper wires, magnesium oxide, coumarone-indene resin, rubber, barium sulfate, pottery clay and an M accelerant are used as raw materials, and the rubber is used as a binding agent; the raw materials are added into a stirring machineand are uniformly stirred to prepare a mixture; the mixture is hotly pressed and molded through a mold to prepare the rubber soft brake pad for the automobile. The rubber soft brake pad for the automobile is provided with a friction body and a mounting technical hole. The rubber soft brake pad for the automobile, provided by the invention, can be widely applied to large-size trucks, buses, agricultural vehicles and civilian cars; the rubber soft brake pad is prepared by taking the rubber as the binding agent and is a rubber soft brake pad prepared without asbestos, phenolic resin and a metalpowder material. By adopting the rubber soft brake pad, the urban buses have no noises in a braking process and do not cause pollution; damages to wheel hubs are not caused, the buses do not slip in rainy and snowy days and the safety coefficient is high; the safety, comfort and wear-resisting performance of the urban buses are greatly improved and the service life of the vehicles is prolonged.
