Abstract

The invention discloses a water-borne rusty anticorrosive primer and a preparation method thereof. The water-borne rusty anticorrosive primer comprises the following raw material components in parts by weight: 20-30 parts of water-borne modified alkyd resin, 0.2-1 part of a defoamer, 0.1-1 part of a dispersant, 0.1-1 part of an anti-flash rust agent, 0.5-2 parts of a thickener, 0.1-0.5 part of a pH regulator, 0.1-0.5 part of a leveling agent, 0.1-1 part of a drier, 0.1-1 part of a wetting agent, 0.5-2 parts of a rust converter, 0.1-0.5 part of an anti-mildew thixotropic agent, 30-40 parts of pigments and fillers, 0.5-3 parts of a cosolvent and 30-40 parts of deionized water. The water-borne rusty anticorrosive primer provided by the invention has excellent water resistance, acid and alkaliresistance and salt spray resistance, can be directly applied to a corroded metal surface without strict rust removal and surface treatment, and is quite suitable for large steel components which aredifficult to be thoroughly surface-treated, and has broad application prospects and development potential.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anti-corrosion primer with rust and a preparation method thereof. Background technique [0002] Traditional solvent-based two-component polyurethane coatings have the advantages of low film-forming temperature, strong adhesion, good abrasion resistance, high hardness, good chemical resistance and weather resistance, and are widely used as industrial protection, wood furniture and automotive coatings. However, with the continuous implementation and improvement of environmental protection policies and the continuous enhancement and improvement of consumers' environmental protection awareness, the use of solvent-based coatings has been restricted unprecedentedly. Traditional oil-based coatings are gradually being replaced by environmentally friendly coatings. The representative environmental protection paint is an important part of the vigorous development of modern g...
