Abstract
The invention discloses waterborne anticorrosive paint, relates to anticorrosive paint, and overcomes a problem that waterborne anticorrosive paint at present is poor in salt-fog resistance and ageing resistance. The waterborne anticorrosive paint disclosed by the invention comprises 260 parts by weight of water, 1.2 parts by weight of a dispersant, 2 parts by weight of a wetting agent, 30 parts by weight of acrylic acid, 1.2 parts by weight of a defoaming agent, 200 parts by weight of pigment, 100 parts by weight of a rust-proof material, 120 parts by weight by weight of a filler, 200 parts by weight of an emulsion, 15 parts by weight of a coalescing agent and 3 parts by weight of a thickening agent. Preparation of the waterborne anticorrosive paint includes adding the water firstly into a reactor, adding the wetting agent, the dispersant and the defoaming agent under stirring, adding the pigment and the filler under stirring, adding the acrylic acid, the emulsion and the rust-proof material, pumping the materials into a grinder, grinding, dispersing, grinding, and adding the coalescing agent and the thickening agent in a blending kettle. The waterborne anticorrosive paint can resist salt-fog for 1000 h, and is excellent in corrosion resistance, good in toughness and good in flexibility. The VOC content of the waterborne anticorrosive paint is only 59.4 g / L. The waterborne anticorrosive paint is convenient to clean and convenient in construction and can be used in match with various kinds of solvent type paint.
Description
technical field [0001] The invention relates to anticorrosion paint, in particular to a water-based anticorrosion paint. Background technique [0002] The existing water-based anti-corrosion paints on the market have very low anti-corrosion performance, salt spray resistance is only 200-300 hours, aging resistance is only 100 hours, and its flexibility and bendability are very poor. [0003] In order to meet the needs of the market, it is urgent to develop a high anti-corrosion paint. However, technical problems such as the modification of film formers, the upgrading of pigments and fillers, and the increase or decrease of additives have always restricted the research and development of high anti-corrosion paints. Contents of the invention [0004] The invention aims to solve the problems of low salt spray resistance and aging resistance of the existing water-based anticorrosion paint, and provides an anticorrosion paint to prolong the time of salt spray resistance and agi...
