Abstract

The invention discloses a black phosphating solution for automobile brake disks, which comprises the following raw materials in parts by mass: 6-9 parts of manganous chloride, 7-10 parts of iron trichloride, 10-15 parts of antimony trichloride, 13-18 parts of 13-18, 10-14 parts of sodium molybdate, 4-7 parts of potassium chlorate, 16-20 parts of hydrochloric acid, 15-19 parts of phosphoric acid, 80-100 parts of maleic acid / acrylic acid copolymer, 0.1-0.2 part of dispersing agent and 780-840 parts of deionized water. The black phosphating solution for automobile brake disks has low treatment temperature, and the treated automobile brake disk black phosphating solution film has compact structure, bright coating, wear resistance and high rust resistance. The black phosphating solution for automobile brake disks has the advantages of low production cost, no environment pollution and good product quality, and is simple to operate.

Description

technical field [0001] The invention relates to the technical field of phosphating solution, in particular to a black phosphating solution for automobile brake discs. Background technique [0002] In recent years, with the rapid development of the automobile industry, the demand for automobiles has increased year by year. Brake discs, as the main wear and tear parts in the automobile braking system, have a large market demand. As the performance and driving speed of vehicles are constantly improving, disc brakes have become the mainstream of the current braking system in order to increase the stability of braking when vehicles are running at high speeds. Because the disc brake disc is exposed to the air, the disc brake has excellent heat dissipation. When the vehicle brakes suddenly at high speed or brakes multiple times in a short period of time, the braking performance is less likely to decline, allowing the vehicle to gain Better braking effect to enhance vehicle safety....
