Description

A kind of staircase use is from dry protective coating and coating process in wet condition thereof
Technical field
The present invention relates to a kind of aqueous self-drying protective coating, especially a kind of staircase use is from dry protective coating.The invention still further relates to this staircase use from dry protective coating coating process in wet condition.
Background technology
Continue after announcing on October 1st, 2015 " volatile organic matter Pollution Charges Site way ", the environmental consciousness of people strengthens day by day, the regulation of subtend atmospheric environment discharge noxious solvent is increasingly strict, has become the inexorable trend of coating industry development with water to replace organic solvent.Aqueous self-drying protective coating is solvent because of it with water, avoids the safety problem such as inflammable and explosive brought containing organic solvents such as benzene classes and environmental protection, health problem and be more and more subject to market and welcome.Staircase is a kind of large-scale workpiece reaching tens of meters, is welded by different structural parts, and complex structure, not easily sprays, because volume is excessive, and usually outdoor spraying and without baking-curing; Before spraying, workpiece is usually with the floating rust of part, conventional electrophoretic painting or robot application cannot operate, current domestic manufacturer generally adopts high pressure to mix gas blowout and is coated with, disposable spray finishing thickness reaches 60-80 microns, thus simplification coating process, reduce production cost, therefore, to anti-sudden strains of a muscle of coating drying property in wet condition, sag prevention, disposable thick painting, single coating erosion resistance and ground property of becoming rusty, all there is higher requirement.Current domestic staircase application is mainly based on solvent-borne alkyd system, epoxy systems, epoxy ester system coating; there is serious inflammable and explosive danger, VOC discharge is high, has a strong impact on the healthy of spraying workman; therefore, staircase application is badly in need of to environmental protection, low carbonization future development.
