Preparation method of antioxidation paint composition

Abstract

The invention relates to a preparation method of an antioxidation paint composition. The paint composition comprises multiple different types of resins and assistants. Due to the combination of the components, the paint composition has the advantages of favorable ultraviolet irradiation resistance and favorable temperature difference change resistance.

Description

technical field

[0001] The invention relates to an anti-oxidation coating composition, in particular to a preparation method of the composition. Background technique

[0002] With the development of the national economy and high technology, the demand for special coatings is increasingly urgent in addition to general-purpose coatings. Among many functional coatings, thermal insulation and anti-oxidation coatings are an important functional coating. Mild oxidation protection. There are still many problems in the temperature control effect and oxidation resistance of the existing thermal insulation and anti-oxidation coatings, which still need to be improved. Contents of the invention

[0003] In order to overcome the deficiencies in the prior art, the invention provides a kind of anti-oxidation coating composition and preparation method thereof, used many different types of resins and auxiliary agents in this coating composition, the combination of each component makes it...

Examples

Embodiment 1

[0019] Acrylic resin preparation:

[0020] In parts by weight, take 30 parts of ethanol and 15 parts of isopropyl acetate, mix them uniformly, add them into the reactor, heat up to 80°C at a rate of 10°C / min, keep the temperature for 30min, and then add 20 parts of methyl acrylate, 10 parts of methacrylic acid, 10 parts of hydroxyethyl acrylate, 2 parts of acetylacetonacrylamide, 1 part of azobicyclohexylcarbonitrile, stir and mix evenly, react at constant temperature for 5 hours, cool down to 30°C, add 1.0ml of ammonia water dropwise, Stir for another 20 min to obtain an acrylic resin.

[0021] Preparation of paint:

[0022] Take 60 parts of deionized water, 10 parts of styrene-acrylic acid copolymer emulsion, 10 parts of polyvinyl chloride resin, 5 parts of alkyd resin, 2 parts of distyrylphenol polyoxyethylene ether, mix them into the reaction kettle, and add them to the reactor at 500 Stir and disperse at a rate of rpm for 30 minutes to obtain a mixed solution A.
