Water-based double-component corrosion-resistant industrial paint and production method thereof

Abstract

The invention discloses a water-based double-component corrosion-resistant industrial paint which is prepared from a component A and a component B. The component A is an acrylic acid epoxy hybrid emulsion prepared by grafting an epoxy group with reaction activity on the acrylic acid main chain, and is 100 parts by weight. The component B is composed of the following components in parts by weight: 20-25 parts of water, 0.1-1.0 part of wetting and dispersing agent, 0.1-0.5 part of defoaming agent, 10-15 parts of antirust pigment, 2-4 parts of functional antirust pigment, 15-25 parts of tinting pigment, 30-35 parts of filler, 8-12 parts of fatty amine curing agent, 1-2 parts of preservative, 0.5-1.0 part of thickener and 0.2-0.5 part of leveling agent. The invention also discloses a production method of the water-based double-component corrosion-resistant industrial paint. The solid content of the water-based double-component corrosion-resistant paint reaches 65% or above, the hardness reaches H, and the adhesion reaches Grade 0. The water-based double-component corrosion-resistant paint can resist water and brine for 7 days, and has favorable solvent resistance and salt spray resistance. The VOC (volatile organic compound) content is less than 50g / l.

AI Technical Summary

Problems solved by technology

[0004] First, the quality of solid content is low, and the construction solid content is generally less than 50%, and there is no active ingredient exceeding 60%.

[0005] Second, low hardness, poor water resistance, solvent resistance, acid and alkali resistance, salt spray resistance generally does not exceed 400h

[0006] Three, the cost is high and the quality is poor, and the paint will rust on the metal surface within half a year

[0007] Fourth, VOC can only be less than 120g / l
