Preparation process of anti-corrosion layer based on thermosetting resin and silicon carbide particles

Abstract

The preparation process of the wear-resistant layer based on thermosetting resin and silicon carbide particles includes the following steps: 1) making an assembled mold; 2) preparing a filler for the wear-resistant layer; the filler is silicon carbide coated with a thermosetting resin 3) Fill the prepared anti-corrosion layer filler in the assembled mold to be filled and tamp and compact it, and heat to cure the thermosetting resin coated on the surface of the silicon carbide particles in the prefabricated mold to make the anti-corrosion The layer filling material is shaped in the metal substrate or metal component to be equipped with an abrasion-resistant layer and forms an abrasion-resistant rough embryo: 4) Prepare a grouting slurry according to a thermosetting resin, and inject it into the shaped anti-wear layer to be installed. In the holes of the metal substrate of the abrasive layer or the overall wear-resistant rough blank of the metal component; 5) Heating to solidify the grouting slurry. The invention provides a preparation process based on the bonding of thermosetting resin and silicon carbide particles on a metal base material (metal member) to form an anti-wear layer with remarkable wear resistance.

AI Technical Summary

Problems solved by technology

At present, the methods to solve the problems of wear resistance and corrosion resistance at home and abroad are as follows: 1) All-metal pumps and pipelines have the advantages of high strength, good rigidity and toughness, and the disadvantages of poor wear resistance and corrosion resistance

2) Metal and rubber-lined pumps and pipes have the advantage of good corrosion resistance, but the disadvantage of poor wear resistance

3) Metal-embedded pumps and pipes with ceramic linings have the advantages of excellent wear resistance and corrosion resistance, but the disadvantage is that the joints of ceramic sheets are easily damaged

4) The pumps and pipes that are formed by mixing epoxy resin and silicon carbide particles on the metal substrate have the advantages of excellent wear resistance and corrosion resistance. Particles are unevenly distributed or layered, and the resin sandwiched between silicon carbide particles reduces the impact resistance of silicon carbide single particles, thereby greatly reducing the wear resistance of the product; followed by mold requirements for castable products It has anti-sticking and excellent sealing performance, so it is difficult to make a mold with a large volume
