Abstract
The invention discloses a salt-water-resistant waterborne acrylic coating. The salt-water-resistant waterborne acrylic coating comprises the following raw materials in parts by weight: 140-180 parts of waterborne epoxy-modified acrylic emulsion, 20-30 parts of fumed silica, 14-20 parts of heavy calcium carbonate, 6-10 parts of precipitated barium sulfate, 10-16 parts of coal gangue powder, 2-4 parts of tetrabutyl titanate, 4-8 parts of water-based defoamer, 3-6 parts of coalescing agent, 2.5-4.5 parts of antifreeze, 2.5-4.5 parts of water-based wetting and leveling agent, 2.5-4.5 parts of water-based preservative, 2.5-4.5 parts of water-based thickener, and 100-140 parts of water. According to the salt-water-resistant waterborne acrylic coating, the obtained coating has excellent curing performance, has a large coating film density, has excellent adhesion, and has extremely high salt water resistant performance, and meanwhile, the phenomenon of coating film sagging is overcome, and thecoating has a long service life.
Description
technical field [0001] The invention relates to the technical field of water-based paints, in particular to a water-based acrylic paint resistant to salt water. Background technique [0002] With the further improvement of environmental protection regulations, new coatings with low VOC or zero VOC emissions have become the focus of research and development for the purpose of reducing the load on the earth, and the research and development of water-based wooden door coatings has attracted more attention. [0003] In recent years, my country's research and development of water-based wood coating technology has been very active, especially water-based coatings represented by water-based acrylic coatings. Wooden door coatings can replace solvent-based wood coatings, and their environmental protection and social and economic benefits are very significant. However, the current water-based acrylic coatings have the disadvantages of poor adhesion and salt water resistance that canno...
