Embodiment 1

[0019] The low-temperature water-based anticorrosion metal coating of the present invention comprises the following components in parts by weight:

[0020] 10-15 parts of poly-o-cresyl glycidyl ether, 15-20 parts of bisphenol F epoxy resin, 10-20 parts of polyphenyl glycidyl ether, 20-30 parts of silica sol, 3-10 parts of coloring Pigment, 1-5 parts of curing agent, 30-60 parts of water, 6-10 parts of dibutyl fat, 8-10 parts of salicylic acid, 1-6 parts of propiconazole, 0.6-1.6 parts of chromium oxide green, 15-20 parts Parts of benzoic acid, 30-60 parts of styrene-acrylic emulsion.

[0021] The present invention adopts poly-o-cresyl glycidyl ether, bisphenol F type epoxy resin, polyphenyl glycidyl ether and silica sol as film-forming substances; bisphenol F is the various isomers of bisphenol F (accounting for about 90% ) and a small amount of trihydric phenol, and the epoxy resin made from it contains a small amount of branched chain structure. The bisphenol F type epoxy r...

Embodiment 2

[0024] Based on Example 1, the curing agent includes the following components: modified aromatic amine, formaldehyde, boron trifluoride, thioethylene glycol, siloxane coupling agent, and polypropylene glycol diglycidyl ether. The curing agent synthesized by modified aromatic amine, formaldehyde, boron trifluoride, thioethylene glycol, siloxane coupling agent and polypropylene glycol diglycidyl ether can cure quickly at low temperature and has good corrosion resistance. impact on the human body and the environment.

Embodiment 3

[0026] Based on the above embodiment, the low-temperature water-based anti-corrosion metal coating also includes the following components in parts by weight: 5-10 parts of mica powder, 30-40 parts of modified wollastonite, 1-2 parts of quartz powder, 3- 5 parts of silicon oxide, 1-4 parts of ground calcium carbonate. Mica powder, modified wollastonite, quartz powder, silicon oxide, and heavy calcium carbonate work together to have a good combination with other materials, and the hardness, chemical corrosion resistance and adhesion of the coating are further enhanced. The low-temperature water-based anti-corrosion metal coating also includes the following components in parts by weight: 3-5 parts of zinc oxide and 10-15 parts of zinc phosphate. Silica sol particles react with zinc oxide and zinc phosphate particles to form a three-dimensional network structure of Si-O bonds. At the same time, silica sol can also bond with the substrate to form a zinc-iron silicate complex. The ...

Abstract

The invention discloses a low-temperature water-based corrosion-resistant metal coating which comprises the following components in parts by weight: 10-15 parts of polyo-toluene glycidyl ether, 15-20 parts of bisphenol F epoxy resin, 10-20 parts of polyphenyl glycidyl ether, 20-30 parts of silica sol, 3-10 parts of a coloring pigment, 1-5 parts of a curing agent, 30-60 parts of water, 6-10 parts of dibutyl ester, 8-10 parts of salicylic acid, 1-6 parts of propiconazole, 0.6-1.6 parts of chromium oxide green, 15-20 parts of benzoic acid and 30-60 parts of a styrene-acrylic emulsion. The coating disclosed by the invention is good in film-forming property and high in film strength, and selects a natural and pollution-free corrosion-resistant agent from a water-based epoxy resin coating; the natural corrosion-resistant agent is bonded with a special emulsion for the water-based corrosion-resistant coating, so that the corrosion resistance is good and superior to that of a traditional water-based coating.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a low-temperature water-based anti-corrosion metal paint. Background technique [0002] With the rapid development of modern industry, the anti-corrosion of metal surfaces has been paid more and more attention by all walks of life. It is an economical and effective method to use paint to coat anti-corrosion. For industrial and mining enterprises, the huge economic losses caused by metal corrosion are incalculable, accounting for about 15%-20% of global steel production. It can be seen how important corrosion protection is. There are many ways to prevent metal corrosion, such as the use of electroplating and cathodic protection, which cause emission pollution and are not conducive to environmental protection; there is also the use of corrosion-resistant alloys, which play an anti-corrosion role, but the project cost is high. It has been proved by practice that the protection of paint layer ...
