Abstract

The invention discloses an abrasion-resistant coating for casting surfaces. The abrasion-resistant coating is prepared from the following components in parts by weight: 3 to 5 parts of ultra-high molecular weight polyethylene, 7 to 9 parts of silicon micro-powder, 6 to 10 parts of rubber powder, 2 to 5 parts of graphite powder, 24 to 32 parts of epoxy resin, 11 to 22 parts of chlorinated polyethylene, 11 to 17 parts of carborundum, 1 to 3 parts of anti-settling agent, 3 to 7 parts of magnesium hexasilicate, 14 to 20 parts of fiberglass particles, 2 to 10 parts of potassium octatitanate, 1 to 4parts of white mica powder, 1 to 3 parts of leveling agent, 2 to 7 parts of poly-benzenedimethanol, 3 to 10 parts of polyurethane powder, 9 to 12 parts of benzenesulfonic acid, 2 to 5 parts of defoamer, 11 to 22 parts of abrasion-resistant ceramic particles, 4 to 9 parts of photoinitiator, 11 to 22 parts of melamine resin, 1 to 5 parts of plasticizer, 2 to 4 parts of dispersant, and 3 to 5 partsof cosolvent. The abrasion-resistant coating has the advantages that the abrasion-resistant property of the casting surface is obviously improved; by adopting the scientific and reasonable design of surface coating, the service life of the casting is greatly prolonged, and the use property of the casting is guaranteed; the preparation of the whole coating is simple, the materials are convenient toobtain, and the good application and popularization value is realized.

Description

technical field [0001] The invention belongs to the field of wear-resistant materials, in particular to a wear-resistant paint used on the surface of castings. Background technique [0002] Castings play a very important role in people's daily life and are essential parts in the process of equipment assembly. How to improve the wear resistance of castings has always been a problem to be solved. The existing paint for the surface of castings has low abrasion resistance, poor scratch resistance and gloss, and low aging resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, provide a wear-resistant coating for the surface of castings, and effectively improve the wear resistance of the casting surface. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions: ...
