High-temperature resistant mechanical coating

Abstract

The invention discloses a high-temperature resistant mechanical coating, comprising the following components in parts by weight: 100 parts of butylated urea resin, 36-41 parts of epoxy resin, 12-19 parts of vinylidene chloride, 3-10 parts of alkyd polyurethane and 1-5 parts of pine oil. The high-temperature resistant mechanical coating disclosed by the invention still has good caking property when being in the sun or in a high-temperature environment for a long period of time; and the operation safety of mechanical components under the high-temperature condition is ensured.

Description

technical field [0001] The present invention relates to a coating. Background technique [0002] Mechanical coating refers to the coating applied on the surface of machinery and various machine parts. Mechanical coatings have the following properties: [0003] (1) Covering power: [0004] The hiding power is usually expressed by the weight of the paint required to cover the specified black and white grid, and the greater the weight, the smaller the hiding power. [0005] (2) Smudge adhesion: [0006] Indicates the adhesion between the coating film and the base layer. [0007] (3) Viscosity: [0008] The viscosity affects the construction performance, and different construction methods require different viscosities of coatings. [0009] (4) Fineness: [0010] The fineness directly affects the smoothness and gloss of the coating film surface. [0011] The main function of the existing mechanical coatings is to prevent the mechanical parts from being isolated from the o...
