High-temperature-resistant and corrosion-resistant paint for instrument shell, and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant paint. The high-temperature-resistant and corrosion-resistant paint is characterized by comprising the following raw materials in parts by weight: 30 to 35 parts of cyanamide resin, 1 to 2 parts of ferric pyrophosphate, 5 to 6 parts of iron oxide red, 2 to 4 parts of glycolic acid, 3 to 5 parts of glass flake, 5 to 8 parts of polycarbonate, 3 to 5 parts of silicon-aluminum oxide powder, 2 to 3 parts of epoxidized soybean oil, 12 to 16 parts of rosin cis-butenedioic acid glyceride, 1 to 2 parts of coconut oil diethanolamine, 0.5 to 1.0 part of ozocerite oxide, 0.5 to 1.0 part of dicumyl peroxide, 0.5 to 0.7 part of fumed silica, 3 to 4 parts of aluminum dihydrogen tripolyphosphate, 2 to 4 parts of quartz powder, 7 to 9 parts of acetone, 12 to 16 parts of butyl acetate and 4 to 7 parts of an additive. Aluminum dihydrogen tripolyphosphate added into the paint disclosed by the invention has high corrosion resistance and high high-temperature resistance; the glass flake serving as a filler is added into the paint, so that the paint has high chemical resistance, high anti-aging resistance, high cohesiveness and high corrosion resistance; the added additive promotes the uniform dispersion of the filler in the paint; moreover, damping and noise reducing functions to some extent are also realized, and the damage of noises to human bodies is weakened.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a high-temperature-resistant anti-corrosion paint for an instrument housing and a preparation method thereof. Background technique [0002] Anti-corrosion paint is a type of paint that can be used on the surface of an object to protect the interior of the object from corrosion. In recent years, most of the industrial anti-corrosion paints are used to protect the surface of metal and other materials, so that they can avoid corrosion and have a longer service life. With the gradual strengthening of people's awareness of environmental protection, more and more researchers pay attention to water-based paints. However, the metal paints prepared from these water-based emulsions have poor compactness and high water vapor transmission rate due to their large particle size and poor film-forming properties. At the same time, although water-based paints are environmentally friend...

With the gradual strengthening of people's awareness of environmental protection, more and more researchers pay attention to water-based paints. However, the metal paints prepared from these water-based emulsions have poor compactness and high water vapor transmission rate due to their large particle size and poor film-forming properties. At the same time, although water-based paints are environmentally friendly and can protect the surface of metals and other materials to a certain extent, compared with solvent-based paints, they often have insufficient bonding strength, resulting in greater brittleness of the cured paint film and insufficient bonding strength. It is easy to cause the paint film to crack or fall off
