Problems solved by technology

[0002] At present, the anti-corrosion primers for the inner and outer walls of steel storage tanks in oil fields mostly use solvent-based anti-corrosion coatings. The organic solvents contained in this coating volatilize in large quantities during production and construction, causing environmental pollution, personnel injury and waste of resources.

Abstract

The invention relates to waterborne epoxy iron red shop primer and a preparation method thereof. The waterborne epoxy iron red shop primer contains two compositions; A composition is prepared by the steps of dissolving epoxy-modified waterborne amine hardener in deionized water, then adding wetting dispersant, polymethyl siloxane, iron oxide red, precipitated barium sulfate, sericite, compound ferrotitanium powder, and aluminium triphosphate, and mixing, blending and grinding the mixture; B composition is prepared by mixing and blending bisphenol-a-type epoxy resin and butyl glycidyl ether. The waterborne epoxy iron red shop primer is safe and environment-friendly and can be used as anticorrosive shop primer for interior and exterior walls of steel oil storage tanks in oil fields.

Description

technical field [0001] The invention relates to a water-based epoxy iron red primer and a manufacturing method, which can be used as an anti-corrosion primer for the inner and outer walls of steel storage tanks in oil fields. Background technique [0002] At present, the anti-corrosion primers for the inner and outer walls of oilfield steel storage tanks mostly use solvent-based anti-corrosion coatings. The organic solvents contained in this coating volatilize in large quantities during production and construction, causing environmental pollution, personnel injury and waste of resources. .
