Oil stain-resistant and antirust water-based modified acrylic iron red primer and preparation method thereof

Abstract

The invention provides an oil stain-resistant and antirust water-based modified acrylic iron red primer and a preparation method thereof. The primer comprises, by mass, 22.5-30% of a water-based acrylic emulsion, 3-10% of a waterborne epoxy ester resin, 0.25-0.5 % of a water-based dispersant, 0.2-0.4% of a water-based defoaming agent, 0.1-0.4% of a water-based base material wetting agent, 0.4-0.8% of an anti-flash rust agent, 5.3-10.1 % of deionized water, 3-6% of a film-forming additive, 0.2-0.4% of a drier, 0.3-0.5% of organic bentonite, 0.3-0.5% of fumed silica, 10-15% of iron oxide red, 27-32% of coarse whiting, 4-7% of water-based zinc phosphate, 3-5% of sericite, 3-4% of water-based aluminum phosphate and 0.2-0.4% of a water-based thickener. The product disclosed by the invention has the characteristics of good substrate oil stain resistance, good wetting adhesion on an oily repaired workpiece, and good wetting adhesion on a smooth curved surface, and a thick film formed by theproduct has the characteristics of no cracking, excellent impact bending resistance, good freeze-thaw resistance stability, good water resistance, excellent corrosion resistance, good heat resistanceand excellent adhesion; and the product can be widely applied to the fields of various large steel structures, automobile chassis paints, automobile water tanks, train chassis paints and engineering machines.

Description

technical field [0001] The invention relates to the field of paint making, in particular to a water-based modified acrylic iron red oil-stain-resistant and anti-rust primer and a preparation method thereof. Background technique [0002] With the economic development, people have higher and higher requirements for environmental quality and physical health, and the country has stricter environmental protection requirements. Oil-to-water has become one of the main development directions recognized by the coatings industry. Water-based coatings are about to usher in huge opportunities for development. While improving the various performance indicators of water-based paints, everyone also encountered problems such as water-based acrylic paints on smooth surfaces, especially smooth curved surfaces, incomplete treatment of oil stains on substrates, and difficult wetting and adhesion of oil-based paints on reworked workpieces. [0003] For oil resistance, the current treatment metho...

[0002] With the economic development, people have higher and higher requirements for environmental quality and physical health, and the country has stricter environmental protection requirements. Oil-to-water has become one of the main development directions recognized by the coatings industry. Water-based coatings are about to usher in huge opportunities for development. While improving the various performance indicators of water-based paints, everyone also encountered problems such as water-based acrylic paints on smooth surfaces, especially smooth curved surfaces, incomplete treatment of oil stains on the substrate, and difficult wetting and adhesion of oil-based paints on reworked workpieces.

[0003] For oil resistance, the current treatment method for water-based coatings is to add oil resistance additives, but the oil resistance additives are expensive, and the dosage is small and ineffective, and the dosage is large, and the cost is expensive. Poor effect, poor adhesion
