Abstract

The invention discloses a medium-resistance wear-resistant coating for a semiconductive rubber roller, which is prepared from the following raw materials in parts by weight: 95-110 parts of thermosetting liquid phenol formaldehyde resin, 15-25 parts of organic acid curing agent, 6-7.5 parts of polyurethane conductive agent, 0.02-0.05 part of organosilicon leveling agent and 0.003-0.006 part of polyether modified silicon oil defoaming agent. The invention also discloses a preparation method of the medium-resistance wear-resistant coating. The resistance of the medium-resistance wear-resistant coating is 10<6>-10<7> orders of magnitude ohm, and conforms to the operating requirement; the medium-resistance wear-resistant coating enhances the wear resistance of the semiconductive rubber roller in the medium-carbon powder chest of the laser printer, lowers the replacement rate of the semiconductive rubber roller, enhances the properties, prolongs the service life, and greatly enhances the number of pieces of printer paper from 3000-5000 to 36000-42000.

Description

technical field [0001] The invention relates to a wear-resistant coating and a preparation method thereof, in particular to a medium-resistance wear-resistant coating for semiconductive rubber rollers and a preparation method thereof. Background technique [0002] In the toner cartridge of traditional laser printers, semi-conductive rubber rollers are mainly divided into charging rubber rollers, developing rubber rollers and powder feeding rubber rollers. Under the overall related collocation, the actions of printing text and images, etc. are carried out. Therefore, the friction between the semi-conductive rubber roller and the printing paper is a kind of damage to the rubber roller. [0003] No matter what type of semi-conductive rubber rollers are on the market, they must go through this performance wear, so the treatment of the surface coating of the rubber rollers is extremely important. [0004] In the general traditional semi-conductive rubber roller industry, coating...
