Problems solved by technology

[0004] Although the overall process describes the entire production process of ceramic brake pads, it does not describe the components of the raw materials for the production of ceramic brake pads. Therefore, it is impossible to estimate the high temperature resistance of ceramic brake pads. Therefore, it is urgently needed. A kind of high temperature resistant ceramic brake pad and its production process

Abstract

The invention discloses a high-temperature-resistant ceramic brake pad and a production process thereof, and relates to the technical field of ceramic brake pad production to solve the problem that high temperature resistance of a brake pad cannot be estimated. The high-temperature-resistant ceramic brake pad comprises a steel backing; a noise reduction piece is arranged on the outer wall of the top of the steel backing, and a thermal insulating layer is bonded to the outer wall of the top of the noise reduction piece; and a friction material is arranged on the outer wall of the top of the thermal insulating layer and prepared from sepiolite fibers, asbestos fibers, potassium carbonate crystal whiskers, brass fibers, wollastonite, aramid fibers, aluminium silicate fibers, aluminium silicate, zirconite, cryolite, feldspar, vermiculite, graphite, antimony disulfide, talcum, mica, barite, porous iron powder, boron modified phenolic resin, open-loop polymerized phenolic resin and the like.The high-temperature-resistant ceramic brake pad has high impact-resistance strength, meanwhile the product density is low, the product hardness is low, braking noise is small, and braking duality isnot damaged.

Description

technical field [0001] The invention relates to the technical field of ceramic brake pad production, in particular to a high-temperature resistant ceramic brake pad and a production process thereof. Background technique [0002] With the rapid growth of China's automobile production and sales, the level of China's automobile manufacturing and technology has also been steadily developed and improved. It is also a good opportunity and challenge for auto parts suppliers with independent intellectual property rights and research and development capabilities. Brake pads are one of the most common parts in automobiles. Brake pads are composed of steel sheets and friction substrates attached to the steel sheets. The working principle is that the friction substrates undergo external pressure to generate friction, thereby decelerating the vehicle. the goal of. [0003] The Chinese patent application number is CN201911236118.3, a ceramic brake pad process, the ceramic brake pad proc...
