Abstract

The invention discloses a high-resistance wear-resistant coating for a semi-conductive rubber roller. The high-resistance wear-resistant coating is prepared from the following raw materials in parts by weight: 95-110 parts of thermosetting liquid phenolic resin, 15-25 parts of an organic acid curing agent, 4-5.5 parts of a polyurethane conductive agent, 0.02-0.05 part of an organic silicon flatting agent and 0.003-0.006 part of a polyether modified silicon oil defoaming agent. A preparation method is further provided for the high-resistance wear-resistant coating. The resistance value of the high-resistance wear-resistant coating is 10<7>-10<8> orders of magnitude of ohm and meets the use requirement, meanwhile, the wear-resistant performance of the semi-conductive rubber roller in a toner cartridge of a laser printer is better, the replacement rate of the semi-conductive rubber roller is reduced, the performance is enhanced, the service life is prolonged, more paper is printed, and the printed paper is greatly improved from original 3,000-5,000 pieces to 42,000-50,000 pieces.

Description

technical field [0001] The invention relates to a wear-resistant coating and a preparation method thereof, in particular to a high-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 i...
