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...
