Abstract

The invention relates to the field of coatings, in particular to a wear-resistant and impact-resistant coating. The coating is formed by mixing four groups of mixed liquid including A, B, C and D; the coating comprises 25 to 28 percent of a component A, 20 to 25 percent of a component B, 25 to 28 percent of a component C and 19 to 30 percent of a component D when the coating is mixed. The coating has the advantages of acid resistance, alkali resistance, high-temperature resistance, cold resistance, and wear resistance; the coating is not damaged under the action of normal impact of an oil rod and a drill rod; the use conditions of the oil rod and the drill rod are met; the equipment can be protected better for operation.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a wear-resistant and impact-resistant coating. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating.” It belongs to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compound. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class o...
