Abstract

The invention provides a quick-drying epoxy zinc rich shop primer, which is composed of a main paint vehicle and a curing agent, wherein the weight ratio of the main paint vehicle to the curing agent is 15: (1-5); the curing agent is polyamide; and the main paint vehicle is composed of an epoxy resin, a tinting pigment, an anti-rust pigment, an anti-settling agent and the like. The epoxy zinc rich shop primer provided by the invention is formed by reacting the main paint vehicle with the polyamide curing agent and curing the reaction product into a film; and the epoxy zinc rich shop primer can be applied to the surfaces of steel structures in medium to heavy corrosive environments and water-based acrylic acid, water-based epoxy, water-based polyurethane and appropriate solvent paint can be applied to the surfaces. Besides, the quick-drying epoxy zinc rich shop primer is good in drying performance, simple and convenient in coating operating, and adapted to stream line coating of the existing steel structure materials; and the quick-drying epoxy zinc rich shop primer can be coated to a specified film thickness once and has excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a quick-drying epoxy zinc-rich shop primer. Background technique [0002] Due to the high strength, good toughness and convenient manufacture of steel structures, they are more and more widely used in the modern construction industry. However, its easy-to-corrosion characteristics have brought huge losses to the national economy. In order to prevent steel corrosion, people have invented a variety of methods for the anticorrosion of steel structures. Among the many anticorrosion methods, spraying anticorrosion coatings is the most economical and simple method. [0003] The shop primer was born in the early 1950s, and its successive products include zinc-free phosphating primer, epoxy zinc-rich paint, epoxy iron red shop primer, and inorganic zinc silicate shop primer. At present, inorganic zinc silicate shop primer is the main application variety. Inorganic zinc silicate shop ...
