Problems solved by technology

Many traditional coatings are easy to emit harmful gas after use, which is harmful to human health; although some coatings do not emit harmful gas, they also have the problem of long curing time, and need to cooperate with other tools to accelerate curing, thereby improving the use. cost
[0003] The light-curing coatings in the prior art have the advantages of short curing time, low curing temperature, and low volatile matter, but their waterproof and anti-corrosion properties cannot meet the needs of the current market

Abstract

The invention discloses waterproof corrosion-resistant photocuring paint. The paint comprises, by weight, 15-40 parts of acrylic emulsion, 3-10 parts of polyurethane, 0.5-5 parts of rosin modified phenolic resin, 0.5-2 parts of triethoxyisobutylsilane, 0.5-1.7 parts of carboxymethylcellulose, 0.6-0.9 parts of hydroxypropyl methyl cellulose, 1-4 parts of dipropylene glycol methyl ether, 2-4 parts of potassium chromate, 4-6 parts of aluminium hydroxide, 2-6 parts of preservatives, 1-4 parts of barium sulfate, 2-5 parts of antioxidants, 6-14 parts of photoinitiators, 3-6 parts of defoaming agents, 2-7 parts of a molybdenum compound, 2-6 parts of sodium sulfate and 16-23 parts of water. The photocuring paint has the advantages of being short in curing time, low in curing temperature and low in volatile component, and meanwhile the coating is good in waterproof performance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of light-cured coatings, in particular to a waterproof and anti-corrosion light-cured coating. Background technique [0002] With the continuous development of the paint industry, people will pay more attention to its safety and environmental protection performance and use cost when using paint. Many traditional coatings are easy to emit harmful gas after use, which is harmful to human health; although some coatings do not emit harmful gas, they also have the problem of long curing time, and need to cooperate with other tools to accelerate curing, thereby improving the use. cost. [0003] The light-curing coatings in the prior art have the advantages of short curing time, low curing temperature, and low volatile matter, but their waterproof and anti-corrosion properties cannot meet the current market demand. Contents of the invention [0004] In order to solve the technical problems existing in the background tech...
