Embodiment 1

[0007] Take 50kg of polyaryl silicone resin, put it into the reaction kettle, then add 30kg of glycidyl p-hydroxybenzoate, keep stirring, and simultaneously put in 10kg of acrylic resin, 15kg of mica powder, 15kg of graphene, 10kg of ethyl acetate, butanol 20kg. After uniform stirring, the high temperature resistant anticorrosion coating containing the polyaryl silicone resin can be obtained. Spray the above paint evenly on the surface of stainless steel, and conduct heat resistance and corrosion resistance tests after it is thoroughly dried. The heat resistance test temperature is 450°C and the time is 30h. At a temperature of 450°C, the coating of the present invention has no cracking and foaming within 30 hours, that is, the coating containing the polyimide-modified silicone resin has good heat resistance. For the corrosion resistance test, 3wt% NaCl solution was used to carry out the salt spray resistance test at 30°C for 130 days. The coating has no blistering and crac...

Embodiment 2

[0009] Take 40kg of polyaryl silicone resin, put it into the reaction kettle, add 20kg of glycidyl p-hydroxybenzoate, keep stirring, and simultaneously put in 5kg of acrylic resin, 10kg of mica powder, 10kg of graphene, 5kg of ethyl acetate, butanol 10kg. After uniform stirring, the high temperature resistant anticorrosion coating containing the polyaryl silicone resin can be obtained. Spray the above paint evenly on the surface of stainless steel, and conduct heat resistance and corrosion resistance tests after it is thoroughly dried. The heat resistance test temperature is 500°C and the time is 30h. At a temperature of 500°C, the coating of the present invention has no cracking and foaming within 27 hours, and cracking occurs after more than 27 hours. That is, coatings containing polyimide-modified silicone resins have good heat resistance. For the corrosion resistance test, 3wt% NaCl solution was used to carry out the salt spray resistance test at 30°C for 130 days. The...

Embodiment 3

[0011] Take 45kg of polyaryl silicone resin, put it into the reaction kettle, then add 25kg of glycidyl p-hydroxybenzoate, keep stirring, and simultaneously put in 5kg of acrylic resin, 15kg of mica powder, 15kg of graphene, 5kg of ethyl acetate, xylene 10kg. After uniform stirring, the high temperature resistant anticorrosion coating containing the polyaryl silicone resin can be obtained. Spray the above paint evenly on the surface of stainless steel, and conduct heat resistance and corrosion resistance tests after it is thoroughly dried. The heat resistance test temperature is 450°C and the time is 30h. At a temperature of 450°C, the coating of the present invention has no cracking and foaming within 28 hours, and cracking occurs after more than 28 hours. That is, coatings containing polyimide-modified silicone resins have good heat resistance. For the corrosion resistance test, 3wt% NaCl solution was used to carry out the salt spray resistance test at 30°C for 130 days. ...

Abstract

The invention discloses a high temperature resistant anticorrosive paint comprising polyaryl organic silicon resin. The high temperature resistant anticorrosive paint comprises the following components according to weight ratio: 40-50 parts of polyaryl organic silicon resin, 20-30 parts of p-hydroxybenzoic acid glycidyl ester, 5-10 parts of acrylic resin, 10-15 parts of mica powder, 10-15 parts of graphene, 5-10 parts of acetic ether and 10-20 parts of diluent, wherein the diluent is butanol or xylene. The high temperature resistant anticorrosive paint can resist temperature of 400-500 DEG C, and has a good anticorrosion effect.

Description

technical field [0001] The invention relates to a high temperature resistant anticorrosion paint, in particular to a high temperature resistant anticorrosion paint containing polyaryl silicone resin. Background technique [0002] In industrial production, metal corrosion has attracted more and more attention. Due to the long-term harsh working environment, metal corrosion is inevitable, especially in some high-temperature working environments. There is an increasing demand for coatings that are also corrosion resistant. In recent years, with the development of science and technology, the requirements for high-temperature-resistant anti-corrosion coatings are getting higher and higher. Conventional high-temperature-resistant coatings can withstand lower temperatures, some only about 200 ° C, and the anti-corrosion effect is also poor. Therefore, the development of A coating with good corrosion resistance and high temperature resistance has become a necessity. Contents of t...
