Abstract

The invention provides a friction material, a friction lining and a preparation method thereof. The friction material comprises the following raw materials, by weight, 2 to 4 parts of ceramic microbeads; 8 to 12 parts of steel fiber; 5 to 7 parts of composite mineral fiber; 6 to 10 parts of bismaleimide resin; 3-7 parts of rubber elastic particles, 5-9 parts of particle graphite, 5-9 parts of calcium fluoride, 2-5 parts of aramid pulp, 3-7 parts of titanate lamellar crystals, 5-10 parts of light calcium carbonate, 3-7 parts of silicon carbide, 3-6 parts of calcined aluminum oxide, 10-16 partsof red copper fibers, 6-10 parts of red copper powder, 3-7 parts of ferrous sulfide, 5-8 parts of calcined petroleum coke and 8 parts of zircon sand. The content of each component is reasonably set; synergistic effect is achieved in combination of all the components; when the friction material used for preparing the friction lining, the friction lining has the advantages that the rated braking torque of the friction lining is 27000 Nm, the rated pressure of the friction lining is 1.0 MPa, the friction lining shows excellent heat resistance in long and steep downgrade sections, the friction coefficient change is small, a braking system composed of the friction lining, a brake disc and a brake has high and stable braking torque, and the friction lining is suitable for being used by heavy trucks.

Description

technical field [0001] The invention relates to the field of brake materials, in particular to a friction material, a friction lining and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the road freight industry has developed rapidly, and the market volume of heavy trucks alone has reached more than 6.4 million units. However, vicious accidents related to heavy trucks occur from time to time, causing great loss of life and property. According to incomplete statistics, nearly 30% of heavy-duty truck accidents are caused by brake failure, which is one of the important reasons for heavy-duty truck accidents. How to solve the problem of heavy-duty truck brake failure is worth pondering. [0003] As we all know, due to the fierce competition in the road freight market, in order to ensure profitability, truck operators need to load more trucks and run faster to obtain higher operating efficiency. At present, the appr...
