Abstract

The invention discloses a water-base epoxy zinc-rich priming paint and a preparation method thereof. The water-base epoxy zinc-rich priming paint comprises a host and a curing agent according to the weight proportion of 4:1. The host comprises filming auxiliary, a first anti-settling agent, a second anti-settling agent, an amine epoxy curing agent, dispersant, a defoaming agent, filler and zinc powder, and the curing agent comprises epoxy emulsion, a third anti-settling agent, an anti-flash anti-rust agent and deionized water. The preparation method includes steps of preparing the host and the curing agent and proportioning paint by the host and the curing agent according to the weight proportion of 4:1. By taking water as a main dispersion medium, the water-base epoxy zinc-rich priming paint has quite low volatilizable organic content, light smell, low harms on humans, non-combustible property and unique safety in storage, transport and use, safety potential hazards caused by accumulation of a great quantity of harmful solvents are eliminated, harms on physical and psychological health of constructors are reduced to the greatest extent, and further, the requirements of production efficiency of fast paces of a container production line can be met.

Description

technical field [0001] The invention relates to coatings in the chemical industry field, and relates to an epoxy zinc-rich primer for water-based matching coatings for containers and a preparation method thereof. Background technique [0002] At present, the world's annual output of containers is 3.2 million TEUs, and the annual coating needs are about 300,000 tons, worth about 5 billion yuan. Container coatings used worldwide are basically solvent-based coatings. Solvent-based coatings are conventional varieties that have been widely used in container anti-corrosion construction for a long time. After repeated experiments and adjustments, their excellent construction performance and anti-corrosion performance have been verified in the process of container production and use. Its regular package is as follows: [0003] Outside the box Inside the box Solvent based epoxy zinc rich primer 30μm 30μm Solvent-based epoxy interior paint ...
