Water-borne light antiseptic steel structure paint and preparation method thereof

Abstract

The invention discloses a water-borne light antiseptic steel structure paint and a preparation method thereof. The preparation method comprises the following steps: step one, adding water, a dispersing agent, a defoaming agent and a wetting agent in a stirring bucket to disperse at a low speed for 5 min; step two, adding heavy calcium carbonate, mica powder and barium sulfate in the stirring bucket, dispersing for 1 hour at a high speed to obtain a product I; step three, adding resin and nanometer heat-setting resin in the product I to stir for 10 min at a slow speed to obtain a product II; step four, adding auxiliary film-forming substances, water, a thickening agent, a flatting agent, an anti-flash rust auxiliary agent and pigment in the product II to disperse for 10 min at the middle speed so as to obtain a product III; and step five, filtering the product III through a 200-mesh screen net to obtain the product and packaging. Through the adoption of the water-borne light antiseptic steel structure paint and preparation method thereof, the use amount of the film-forming auxiliary agent is reduced, and the dry condition limitation is improved, the sanding performance of the product is improved so that the product can be automatically dried at a low temperature.

Description

technical field [0001] The invention relates to an anti-corrosion steel structure paint and a preparation method thereof, in particular to a water-based light anti-corrosion steel structure paint and a preparation method thereof, belonging to the technical field of paint preparation. Background technique [0002] Water-dilutable paint refers to the paint prepared by the post-emulsification emulsion as the film-forming substance, so that the solvent-based resin is dissolved in the organic solvent, and then with the help of the emulsifier, the resin is dispersed in water to form an emulsion by strong mechanical stirring, which is called post-emulsion paint. Emulsified emulsion, the paint made can be diluted with water during construction; the currently used post-emulsified resin has low environmental protection, slow drying time, and reduces construction efficiency. It is not much different from solvent-based paint, and its sanding performance is poor; When applied to steel ma...

[0002] Water-dilutable paint refers to the paint prepared by the post-emulsification emulsion as the film-forming substance, so that the solvent-based resin is dissolved in the organic solvent, and then with the help of the emulsifier, the resin is dispersed in water to form an emulsion by strong mechanical stirring, which is called post-emulsion paint. Emulsified emulsion, the paint made can be diluted with water during construction; the currently used post-emulsified resin has low environmental protection, slow drying time, and reduces construction efficiency. It is not much different from solvent-based paint, and its sanding performance is poor; When applied to steel materials, its antirust performance is poor, and rust spots are prone to appear on the surface of steel materials, which shortens the service life of steel materials
