[0003] At present, some manufacturers also try to use epoxy resin plus abrasives (corundum, silicon carbide, high-alumina ceramics) for repair, the effect is mediocre, and it is difficult to reach the service life of the new workpiece, even if it is repaired with imported wear-resistant protective agents, it is often not enough. Half of the life of the new workpiece, frequent disassembly and assembly not only increases the work intensity of the maintenance workers but also affects th...

Abstract
The invention discloses an abrasion-resistant coating material for repairing abrasion of a slurry pump. The material comprises a primary agent and a curing agent, wherein the primary agent comprises 15-60 parts of epoxy resin, 0-5 parts of a coupling agent, 0-20 parts of flexibilizer, 0-600 parts of a grinding material, 0-60 parts of fibers, 0-80 parts of resin alloy polyphenyl ether, 0-30 parts of an antifriction material, 0-20 parts of an thixotropic agent, namely fumed silica, and 0-50 parts of pigment; the curing agent comprises 5-50 parts of organic amine substances, 3-20 parts of a coupling agent, 0.5-18 parts of accelerant, 0-300 parts of a grinding material, 0-10 parts of an thixotropic agent, namely fumed silica and 0-15 parts of pigment. In the actual application process of the coating material for repairing the slurry pump, the service life after repair is conducted can reach 1.5-2 times that of a new workpiece, for the working condition with large material particles repaired, the service life can even reach four times at times, and repeated repair can be conducted.
Description
technical field [0001] The invention relates to a wear-repairing wear-resistant coating material, and more specifically relates to a wear-repairing wear-resistant coating material for a slurry pump. Background technique [0002] Slurry pumps, as a branch of general pumps, are mainly used in places where the pumped slurry contains high solid particles. At present, they are widely used in mineral processing, coal washing, slag discharge, sand pumping, dredging of rivers and ports, etc. Due to the high content of solid particles in the pumping medium, the wear is very serious. Although the manufacturer chooses high-cost high-chromium alloy materials to prolong the service life of the slurry pump, the service life of the pump is the shortest in some special working conditions. As far as the service life is 3 to 10 days, the general service life of the slurry pump running in the mineral processing system is 1 to 3 months. Due to the high cost of the slurry pump, when the fixed e...
