The ISOBAR type brake pad is commonly used for braking and decelerating 300-plus 350km/h motor train units in China, a rigid regulator is designed between a friction block and a steel backing of the ISOBAR type brake pad, generally three friction blocks share one regulator, and in the using process, the friction blocks are mutually regulated through the regulator, so that each friction block acts on a brake disc to brake or decelerate according to the same pressure, the eccentric wear problem can be well solved, and the surface temperature difference of the brake disc can be effectively reduced.

To ensure smooth adjustment of the adjuster, MoS is typically sprayed onto the adjuster surface, particularly the working ball arc₂Lubricant of the MoS₂The lubricant is diluted by the organic solvent and then is uniformly sprayed on the surface of the regulator by a spraying device, and the lubricant can be firmly attached to the surface of the regulator to play a role in lubrication after being dried for a certain time because the lubricant contains colloid. However, the lubricant contains a small amount of toxic and harmful solvent components, and the atomized lubricant is harmful to human health during spraying, so that the safety protection of operators is required to be paid extra attention during spraying.

Currently, MoS spray coating₂Most lubricants are manually operated, i.e. the regulator to be sprayed is placed on a flat plate in a well ventilated place or a place with a waste gas and fly dust recovery device, and a hand-held spray gun is generally adopted to spray the regulator, so that the diluted MoS₂The lubricant is poured into a spray can on the spray gun, and the operation can be carried out after the compressed gas is communicated. After the surface is basically dried after the spraying is finished, turning over the surface and then spraying the other surface. During spraying, operators need to wear the masks meeting the protection requirements and wear protective clothing. Thereby causing the following problems:

1. the spraying process has large peculiar smell and much dust to the organic solvent, has large influence on the environment and has hidden danger to the health of operators;

2. manual spraying, difficult guarantee of thickness and uniformity and large waste of lubricant consumption;
