Problems solved by technology

Both have their own advantages and disadvantages, but relatively speaking, the most fundamental thing is that the comprehensive performance of all aspects of water-based industrial coatings needs to be further improved.
The subsequent water-based industrial coatings use the compound of acrylic acid and water-based polyurethane as the main raw material, which not only inherits the advantages of acrylic products in weather resistance and good construction tolerance, but also improves the hardness of water-based industrial coatings, but the chemical properties and flexibility are still the same. not well resolved
In addition, the main reason restricting the production and application of water-based industrial coatings is that there is still a gap between the performance of water-based industrial coatings and the performance of similar solvent-based industrial coatings

Abstract

The invention relates to an aqueous industrial coating material and a production method thereof, wherein the raw materials comprise, by weight, 30-40 parts of an organic silicon modified acrylic resin, 10-15 parts of a methylated melamine formaldehyde resin, 0.1-2.0 parts of a wetting agent, 0.1-2.0 parts of an anti-foaming agent, 0.1-2.0 parts of a leveling agent, 5-10 parts of an alcohol-based solvent, 5-10 parts of an ether-based solvent, and 35-50 parts of deionized water. According to the present invention, the aqueous industrial coating material has characteristics of no environment pollution, remarkably strong adhesion, excellent leveling property, excellent gloss and the like, is the high-performance aqueous industrial coating material, further has advantages of excellent flexibility, excellent water resistance, excellent damp heat resistance, excellent chemical resistance, excellent salt spray resistance and easy construction, and is suitable for the automated spraying line of the industrial production of metal work-pieces.

Description

technical field [0001] The invention belongs to the technical field of processing PE water supply pipes, and in particular relates to a water-based industrial paint suitable for treating metal surfaces and a production method thereof. Background technique [0002] Objects are exposed to the atmosphere and are corroded by oxygen, moisture, etc., which are likely to cause damage such as metal corrosion, wood decay, and cement weathering. According to statistics, the metals due to rust and corrosion each year in the world account for about 20% of the annual output, and the annual economic losses caused by corrosion in my country account for about 4% of GDP, and the losses even exceed the sum of various natural disasters. And coating the surface of the object to form a protective film can prevent or delay the occurrence and development of these damage phenomena, and prolong the service life of various materials. Coatings can be coated on the surface of objects by different cons...
