Embodiment 1

[0007] Take 20kg of alicyclic epoxy resin and put it into the reactor, then add 20kg of brominated resin, add 30kg of phenolic modified silicone resin, add 5kg of zinc powder, 5kg of kaolin, and 5kg of cyclohexanone. High temperature resistant anticorrosive coating of cyclo epoxy resin. Spray the above-mentioned paint uniformly on the surface of stainless steel, and conduct heat resistance and corrosion resistance tests after being thoroughly dried. The heat resistance test temperature is 500℃, and the time is 40h. At a temperature of 500° C., the coating of the present invention has no cracking and foaming phenomenon within 40 hours, that is, the coating containing alicyclic epoxy resin has good heat resistance. The corrosion resistance test uses 3wt% NaCL solution to conduct the salt spray resistance test at 30°C for 120 days. The coating has no blistering and cracking within 115 days, and blistering after 115 days. The coating has good anti-corrosion performance.

Embodiment 2

[0009] Take 25kg of alicyclic epoxy resin and put it into the reactor, then add 25kg of brominated resin, add 40kg of phenolic modified silicone resin, add 10kg of zinc powder, 10kg of kaolin, and 10kg of cyclohexanone. High temperature resistant anticorrosive coating of cyclo epoxy resin.

Abstract

The invention relates to a high temperature anticorrosive paint comprising cycloaliphatic epoxy resin. The high temperature anticorrosive paint is characterized by comprising the following components according to weight ratio: 20-25 parts of cycloaliphatic epoxy resin, 20-25 parts of bromination resin, 30-40 parts of phenolic aldehyde modified organic silicon resin, 5-10 parts of zinc powder, 5-10 parts of kaolin, and 5-10 parts of cyclohexanone. The prepared high temperature anticorrosive paint comprising cycloaliphatic epoxy resin can resist temperature of 500-600 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 alicyclic epoxy resin. Background technique [0002] In the rapid economic development, the corrosion of metals involved in enterprises has attracted more and more attention. Due to the harsh working environment for a long time, the corrosion of metals is inevitable, especially in some working environments that also involve high temperatures. There is an increasing need to have coatings that are both resistant to high temperatures and corrosion. 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 wit...
