Abstract

This invention relates to a water-based epoxy zinc-rich priming paint. The water-based epoxy zinc-rich priming paint consists of two components, which is prepared by grinding, dispersing and other processes after the main base material of water-based epoxy resin and water-based epoxy curing agent are mixed with zinc powder, filler, additives, co-solvents, water and other ingredients. Safe and convenient in application, the water-based epoxy zinc-rich priming paint has no pollution to the environment and is harmless to the workers. Suitable for high-pressure airless spraying, the water-based epoxy zinc-rich priming panit is provided with high operation efficiency and a single 10-100um thick coating layer. The priming paint has advantages of fast drying, high mechanical strength of paint film, strong adhension and good anticorrosion performance. The priming paint can be used as an anticorrosion and protection layer of steel structure in ships, bridges and containers as well as priming paint of a workshop.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based epoxy zinc-rich primer for containers. Background technique [0002] Traditional container coatings are mostly solvent-based coatings. Common varieties include epoxy, chlorinated rubber, acrylic, polyurethane, etc., which contain a large amount of organic solvents. These solvents are harmful to the health of construction workers and pollute the environment. Since the early 1970s, the development of environmentally friendly anti-corrosion and anti-rust paints such as high solid content, solvent-free, powder and water-based paints has been carried out in foreign countries. Among them, water-based paints have received more research because of their low cost, safe and convenient construction, and easy control of film thickness. . However, due to technical difficulties, great progress has not been made for a long time. Since the mid-1980s, the environmental protection regulations of variou...
