Abstract

The invention discloses a derusting antirust colored heavy-duty single-component primer and a production technique thereof. The primer comprises the following components in parts by weight: 5-20 parts of deionized water, 20-25 parts of derusting rust inhibitor, 2-8 parts of film formation assistant, 2-4 parts of antifreezing agent, 0.1-0.2 part of thickener, 3-10 parts of color paste, 0.3-1 part of defoaming agent, 40-70 parts of film forming matter, 3-5 parts of adhesion modifier and 0.3-0.6 part of substrate wetting agent. The production technique comprises the following steps: mixing the components, and stirring and dispersing in a stainless steel reaction kettle; and after all the indexes are qualified through detection and the stirring is finished, filtering through a 100-mesh filter screen, and packaging. The 1318 or KX-123 product is used as the derusting rust inhibitor, the H602 emulsion is used as the film former, and the film formation assistant, substrate wetting agent, imported color paste and other pollution-free assistants are added to prepare the water-based environment-friendly derusting antirust colored single-component primer. The primer has the advantages of accessible raw materials, derusting labor saving, high antirust property, high safety, environment friendliness and high corrosion resistance.

Description

technical field [0001] The invention relates to a medium anti-corrosion primer coating, in particular to a rust-removable anti-rust colored heavy-duty anti-corrosion single-component primer in the field of heavy-duty anti-corrosion of iron substrates such as water-based steel structures. Background technique [0002] The amount of water-based anti-corrosion coatings used in the field of heavy-duty anti-corrosion is still very low at present, and the reasons are complicated and multifaceted. Some users are more conservative and unwilling to try coating products based on new technologies; there are still few environmental protection regulations in the industrial field; compared with solvent-based coatings, water-based coatings are more expensive, poorer in performance, and have some limitations in use. The benefits of using water as a solvent and diluent for water-based paint are obvious. Not only is it cheap, but it is also non-toxic and odorless, so there is no danger of fir...
