Problems solved by technology

[0003] The existing inorganic zinc silicate shop primers are generally added with polyvinyl butyral or other resins as plasticizers. The existence of these organic resins will inevitably affect its high temperature resistance. When the painted steel structure is welded or cut at high temperature, it will generate smoke, which will affect the operation and seriously affect the environment
In addition, due to the large proportion of zinc powder, anti-sedimentation agents must be added in the production of shop primers, which increases production costs

Abstract

The invention provides an inorganic zinc silicate workshop primer. The Inorganic zinc silicate workshop primer is composed of modified silicate, zinc powder, ferro-phosphorus powder, organic bentonite, corrosion inhibitor, defoaming agents and flatting agents. The ferro-phosphorus powder replaces partial zinc powder in the workshop primer so as to reduce the usage amount of zinc powder, so that the production cost is reduced; meanwhile, a steel member painted with the primer reduces the production of zinc mist while welding or cutting, so that the working environment is improved, the body health of people is ensured, the cracking tendency of coatings can be greatly reduced, and the external smoothness and weather fastness of films are improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an inorganic zinc silicate shop primer. Background technique [0002] 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 primer is generally composed of paint and curing agent composed of high-grade inorganic zinc silicate resin, zinc powder, additives and solvents. It is widely used in pretreatment and polishing of steel plates in metallurgy, containers, various types of transportation vehicles, and engineering machinery. It is especially suitable for rust prevention of steel structures. It is an ideal primer for metal pretreatment shot blasting and antirust maintenance. [0003] The existing inorganic zinc silicate sh...
