Abstract

The invention provides an external protective coating layer of caterpillar bands. The external protective coating layer of caterpillar bands comprises, by weight, 50 to 80 parts of polyurethane resin,5 to 12 parts of mica powder, 2 to 6 parts of a surfactant, 10 to 15 parts of diatomite, 3 to 5 parts of tri-n-butylamine, 5 to 9 parts of a film forming agent, and 1 to 3 parts of an antifoaming agent. The external protective coating layer is capable of improving the wear resistance of caterpillar bands greatly.

Description

technical field [0001] The invention relates to a coating, in particular to an outer protective coating of a track. Background technique [0002] Tracks are driven by flexible links surrounding the drive pulley, road wheels, idlers and track rollers. The track is composed of track shoes and track pins. The track pins connect the track shoes to form a track link. There are holes at both ends of the track shoe, which mesh with the driving wheel, and there are induced teeth in the middle, which are used to straighten the track and prevent the track from falling off when the tank turns or rolls. There are reinforced anti-skid ribs (referred to as patterns) on the side in contact with the ground. , to improve the firmness of the track shoe and the adhesion between the track and the ground. [0003] The crawler chassis is easy to wear during travel, which affects the service life of the track. Contents of the invention [0004] Aiming at the above problems, the present inven...
