Embodiment 1

[0029] This embodiment provides a water-based amino nano-corrosion-resistant industrial coating, which is composed of the following components in parts by weight: 30 parts of water-based acrylic modified alkyd resin, 6 parts of high imino type melamine formaldehyde resin, ethylene glycol mono 5 parts of butyl ether, 2 parts of modified mesoporous silica, 0.5 parts of BYK101, 0.8 parts of HY-5030 silicone leveling agent, 0.8 parts of ethylene glycol phenyl ether, 0.05 parts of BYK302, 10 parts of deionized water. The modified mesoporous silica is obtained by reacting mesoporous silica (with a particle size of 100nm) with KH550.

[0030] The water-based acrylic modified alkyd resin provided by this embodiment is prepared in the following manner:

[0031] (1) Preparation of alkyd resin

[0032] S1: put fatty acid, maleic anhydride, trimethylolpropane, isophthalic acid and refluxing xylene into the reaction kettle, raise the temperature to 180°C and keep it for 1 hour;

[0033] ...

Embodiment 2

[0043] This embodiment provides a water-based amino nano-corrosion-resistant industrial coating, which is composed of the following components in parts by weight: 50 parts of water-based acrylic modified alkyd resin, 10 parts of high imino type melamine formaldehyde resin, ethylene glycol mono 20 parts of butyl ether, 5 parts of modified mesoporous silica, 1 part of BYK101, 1 part of HY-5030 silicone leveling agent, 1 part of ethylene glycol phenyl ether, 1 part of BYK302, 25 parts of deionized water.

Description

technical field [0001] The invention relates to the field of water-based industrial coatings, in particular to a water-based amino corrosion-resistant nanometer industrial coating and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of living standards, in the field of coatings, people pay more and more attention to the environmental protection performance of coatings. Water-based coatings are an important direction of research and development in the field of industrial coatings. Metal corrosion caused by improper protection every year brings huge losses to the national economy and also causes a lot of waste of resources. Nanomaterials have been widely used in coatings due to their unique small size effect, quantum effect and surface interface effect. The application of nano water-based coatings in the field of metal anti-corrosion, through further research to improve its anti-corrosion performance, protects...
