Problems solved by technology

[0007] Since the content of zinc powder in zinc-rich paint (paint) is between 85-95%, it is easy to produce secondary flash rust; the requirements for rust removal of the substrate are high; since zinc powder is an expensive metal mineral, the price starts from 10 yuan /kg soars to more than 30 yuan/kg; for the construction party: the surface treatment of the substrate must be sandblasting and shot blasting to reach the level of mechanical derusting Sa2.5; The upper cover is connected with pain

Abstract

The invention relates to a zinc powder-free water-based primer. The zinc powder-free water-based primer comprises the following components in parts by weight: 4-6 of lithium silicate, 4-9 of emulsion, 13-17 of ferrophosphorus powder, 13-17 of zinc-iron powder, 7-12 of antirust pigment, 0.4-1 of defoaming agent, 0.4-1 of thickening agent, 0.4-1 of film forming aid, 0.4-1 of anticorrosive aid, 0.4-1 of AMP aid, 1.8-2.3 part of accelerant, 0.4-0.8 of fumed silica and a right amount of deionized water. The zinc powder-free water-based primer has the advantages that the secondary rust removal problem caused by zinc powder is eliminated, and the health hazards on constructors and the pollution on environments are eliminated by using water for replacing an organic solvent. The adhesive force of the zinc powder-free water-based primer is obviously superior to that of an inorganic zinc product under the condition of unsatisfactory surface treatment.

Description

technical field [0001] The invention relates to a water-based primer and a preparation method thereof, in particular to a zinc-powder-free water-based primer and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] At present, zinc-rich primers are the most common and important as anti-corrosion and shop primers for steel structures. Zinc-rich coatings are mainly used in the form of zinc-rich primers for anti-corrosion of various steel structures. Because the formula contains a large amount of electrochemical anti-rust pigment-zinc powder, it is called zinc-rich coatings. [0003] Zinc-rich paint film is hard, good adhesion, strong anti-rust ability, has excellent three-proof (moisture-proof, anti-salt spray, anti-mildew) performance and anti-oxidation and anti-corrosion performance; excellent cathodic protection and static electricity. There is no adverse effect on welding performance, and it can be used with most coatin...
