Problems solved by technology

At present, people use anti-corrosion coatings to achieve anti-corrosion protection for metals in daily practice, that is, to spray the finished anti-corrosion coatings on metal components, and rely on the strong combination of these anti-corrosion coatings and the surface of metal components to achieve anti-corrosion. However, most of the anti-corrosion coatings currently used for anti-corrosion of metal components are not very ideal, and they cannot effectively play a real anti-corrosion effect on metal components.
In order to solve this problem, various experiments have been carried out in order to develop and produce anticorrosion coatings with better anticorrosion effects, but so far, people have not produced such anticorrosion coatings for practical applications. Among

Embodiment 1

[0010] Take 85.5 parts of bisphenol A glycidyl ether, 14.5 parts of epoxy resin with an equivalent weight of 371, 27.5 parts of bisphenol A and 15 parts of N-methylethanolamine by weight in the raw materials of this high-efficiency anti-corrosion coating. Base material, then take 100 parts of base material, 50 parts of methyl isobutyl ketone, 64 parts of polyisocyanate, 50 parts of talcum powder, and 50 parts of coal tar according to the weight ratio, mix and stir evenly, and put them into the reaction kettle And keep the temperature at 200-220°C, such as reacting at 210°C for about 20-40 minutes, you can get this high-efficiency anti-corrosion coating.

Embodiment 2

[0012] In this embodiment, each step is consistent with implementation 1, except that the weight ratio of each raw material of the preparation base material is 82 parts of bisphenol A glycidyl ether, 11 parts of epoxy resin with an equivalent weight of 371, 24 parts of bisphenol A, and N-methyl ether. 12 parts of ethanolamine. And when further preparing coating, the weight ratio of each raw material is base material 90 parts, methyl isobutyl ketone 45 parts, polyisocyanate 60 parts, talcum powder 40 parts, coal tar 40 parts.

Embodiment 3

[0014] In this embodiment, each step is consistent with implementation 1, except that the weight ratio of each raw material of the preparation base material is 89 parts of bisphenol A glycidyl ether, 17 parts of epoxy resin with an equivalent weight of 371, 30 parts of bisphenol A, and N-methyl ether. 18 parts of base ethanolamine. And when further preparing coating, the weight ratio of each raw material is 110 parts of base material, 55 parts of methyl isobutyl ketone, 70 parts of polyisocyanate, 60 parts of talcum powder, 60 parts of coal tar.

Abstract

The invention discloses high active anticorrosive paint. Its material includes bisphenol A diglycidyl ether, epoxy resin with 371 equivalent weight, bisphenol A, N-methylethanolamine, and methyl isobutyl ketone, multi- isocyan phenolic ester, talc, and coat tar. It can effectively solve the current metal corrosion problem, and can play the action of protection against corrosion for hardware.

Description

technical field [0001] The invention relates to a paint, especially a high-efficiency anti-corrosion paint emphatically used in the field of anti-corrosion. Background technique [0002] Metal corrosion is a very common phenomenon in nature, which is very harmful to the metal components used in people's daily life and production, especially those metal components in harsh environments, such as bridges, vehicles, Ships, steel structures, chemicals, medicine, electroplating workshops and other structures, upper and lower water pipes, drainage pipes, seawater pipes, etc., are more severely corroded than metal components under normal conditions. In some cases, the annual corrosion depth of metal components It can reach 1-2 mm, and even the corrosion degree of some local parts can reach more than 3 mm per year. This is a very serious problem, so metal anti-corrosion is a problem that people have to solve all the time. At present, people use anti-corrosion coatings to achieve ant...
