[0003] At present, some manufacturers also try to use epoxy resin plus abrasives (corundum, silicon carbide, high-alumina ceramics) to 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 the normal production operation
Relying on the basis of more than ten years of research and development and production of wear-resistant coatings, the inventor also tried to use epoxy materials and wear-resistant polyurethane materials to carry out a large number of mechanical equipment repair experiments, and found that simple epoxy materials and polyurethane materials can extend the use of equipment. Life is still limited

Abstract
A wear-resistant coating material includes a main agent including 10-60 parts of epoxy resin, a curing agent including 5-50 parts of an organic amine substance and 0.5-18 parts of an accelerator, and 0.5-20 parts of a coupling agent, 5-20 parts of a toughening agent, 100-600 parts of an abrasive material, 10-60 parts of fibers and 5-20 parts of a thixotropic agent which are included in the main agent and/or the curing agent. In an actual use process, the wear-resistant coating material enables the life of a new specimen to be extended to 1.5-2 times that of an original specimen, sometimes, enables the life to reach 4 times that of the original specimen under a working condition with a larger-particle material, and also can be repeatedly repaired.
Description
technical field [0001] The invention relates to a wear-resistant coating material. Background technique [0002] In machinery and equipment for the conveying, processing and handling of granules or slurries, metal parts wear out after a period of use and are scrapped. If the wear-resistant coating is used to treat the surface of new metal parts or to repair the worn out metal parts, the service life of the metal parts can be extended and the production cost can be reduced. [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 the normal production ...
