Description
Technical field
The present invention relates to the present invention relates to chemical field, more particularly to a kind of antiseptic and rustproof water-borne acrylic coatings.
Background technology
21st century were green centuries, resource-saving, saved the energy, pollution-free is the main direction of development of world's coating.
The rust-proof anti-corrosive paint overwhelming majority that the country uses at present is solvent based coating, is exactly to pollute ring the shortcomings that these coating maximums
Border, it is inflammable and explosive, it is harmful, and waste substantial amounts of resource and the energy.Solvent based coating product has in existing market
Machine volatile matter VOC content is up to 50%~60%, in nearly 200,000 tons of year discharge organic volatile VOC, not only pollutes environment but also wave
Take the energy, therefore develop the focus place that water-based anticorrosive paint will be domestic and international coating industry.
It is with the base-material of extensive water-based anticorrosive paint in the market now：It is water soluble acrylic acid, aqueous alkide resin, water-based
Epoxy coating etc., wherein water-borne acrylic coatings are various water paint film forming because of the features such as it has excellent weather resistance, easy for construction
The optimal polymer of cost performance in material, but three major issues be present in common water-borne acrylic coatings：1. salt spray resistance is poor,
It is usually no more than 120h 2. to get rusty easily, water paint introduces the water into the construction stage, and irony base material contacts with water, produces flash rusting
3. poor storage stability, antiseptic property is poor, how to solve this three major issues, will be that water-borne acrylic coatings above push away in chemical field
Wide key.
The content of the invention
