A kind of superhydrophobic water-based antirust paint and its preparation process

Abstract

The invention relates to a super-hydrophobic waterborne antirust paint and a preparation process thereof. The super-hydrophobic waterbone antirust paint is prepared from the following raw materials in parts by weight: 240 parts of first emulsion, 130 parts of first group of water, 1 part of first defoaming agent, 3 parts of dispersing agent, 3 parts of paraffins, 30 parts of ethylene glycol monobutyl ether, 2 parts of AMP-95, 120 parts of highlight precipitated barium sulphate, 130 parts of rutile titanium dioxide, 40 parts of mica iron oxide, 240 parts of second emulsion, 1 part of second defoaming agent, 3 parts of antiflash antirust agent, 20 parts of propylene glycol, 30 parts of oversubscription wax emulsion, 4 parts of alkali swelling thickening agent, and 4 parts of second group of water. According to the super-hydrophobic waterbone antirust paint, the cost is effectively lowered, but also favorable effects of the paint on substrate moistening and adhesion are achieved, and an oil shrinkage phenomenon caused by different surface tensions when different substrates are coated with the waterborne antirust paint can be effectively avoided.

Description

Technical field [0001] The invention relates to an anti-rust paint, in particular to a super-hydrophobic water-based anti-rust paint and a preparation process thereof. Background technique [0002] Anti-corrosion paint is a kind of paint that can protect metal surfaces from chemical or electrochemical corrosion in the atmosphere and sea water. It is mainly divided into two categories: physical and chemical anti-rust paint. The former relies on the proper combination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite anti-rust paint, etc.; the latter relies on the chemical rust-inhibiting effect of anti-rust pigments, such as red Dan, zinc yellow anti-rust paint, etc. Used for rust prevention of metals such as bridges, ships, pipelines, etc. The main components of anti-rust paint are anti-rust pigments and film-forming substances. Usually named after the name of the anti-rust paint, su...

Problems solved by technology

Traditional chemical anti-rust paint has certain defects: it has toxic and harmful substances, high VOC content, difficult to dilute, inconvenient construction, not obvious anti-rust and decorative effects, high surface tension, oil, rain, etc. are easy to adhere to the paint It is difficult to completely wet the substrate on the surface of the film, resulting in adverse phenomena such as oil shrinkage
