Problems solved by technology

Water-based acrylic paint has good weather resistance and good adhesion, but its salt spray resistance and corrosion resistance are slightly poor. When it is used in marine or coastal cities, there are always some difficulties; water-based epoxy resin has excellent salt spray resistance, but its weather resistance is poor. long-term outdoor use
Polyurethane products are expensive and limit the application

Abstract

The invention discloses a low-VOC water-based industrial anticorrosive resin and a preparation method and application thereof on a coating. The anticorrosive resin comprises 2-5 parts of epoxy resin,20-25 parts of acrylic acid, 1-3 parts of methyl methacrylate, 0.5-1 part of maleic anhydride, 0.5-1 part of catalyst, 0.01-0.05 part of polymerization inhibitor, 3-6 parts of cosolvent, 0.3-0.5 partof triethanolamine, 0.1-0.3 part of nonionic surfactant, and 30-40 parts of pure water. The low-VOC water-based industrial anticorrosive which is further processed through the low-VOC water-based industrial anticorrosive resin is a high-performance, low-price and low-VOC environmentally-friendly water-based coating and is a good substitute of an industrial anticorrosive paint.

Description

technical field [0001] The invention relates to the field of preparation of environmentally friendly coatings, in particular to a low-VOC water-based industrial anticorrosion resin, a preparation method thereof and an application in coatings. Background technique [0002] At present, domestic anti-corrosion coatings for steel workpieces are mainly solvent-based coatings, while 37% of anti-corrosion coatings for steel workpieces in developed countries in Europe and the United States are water-based coatings. Water-based coatings use water instead of organic solvents to reduce organic solvent emissions. The coating performance can be compared with solvent-based coatings, so the research of water-based coatings has become a research hotspot in this field. [0003] At present, with the strengthening of domestic environmental protection awareness, high-VOC oil-based paints have seriously harmed the environment and the health of construction workers. Therefore, the water-based ind...
