Abstract

The invention relates to the technical field of protective coatings and particularly relates to an acrylic polyurethane silicofluoride coating. The coating is prepared from the following raw materials in percentage by weight: 50-70% of hydroxyl acrylic resin, 10-20% of solvent, 0.1-3% of fluorine-containing micropowder, 1-5% of pigments, 1-3% of high-hardness oxides, 2-5% of assistant and 10-20% of closed isocyanate curing agent. The acrylic polyurethane silicofluoride coating provided by the invention can be used for improving the protective capability to a steel structure and has good characteristics of ageing resistance, scratch resistance, corrosion resistance, discoloration resistance, pollution resistance and the like. Under the condition of being matched with other primers and intermediate coatings with excellent performances, the coating has an extremely good long-acting protective performance to the steel structure and the protective service life can reach 30 years.

Description

technical field

[0001] The invention relates to the technical field of protective coatings, in particular to a fluorinated siliconized acrylic polyurethane coating. Background technique

[0002] With the increasingly widespread application of steel structures, the protection of steel structures has also received more and more attention. At present, a lot of work has been done on the anti-corrosion research of steel structure engineering at home and abroad, such as using a coating with high anti-corrosion fillers (such as zinc powder, cloud iron powder, aluminum powder) as a protective coating, or by Primer and sealing topcoat constitute a composite protective coating, etc. These measures have played a certain role in the protection of steel structures, but some problems have also been exposed. For example, when a layer of zinc-rich paint or high-zinc paint is used for anti-corrosion protection of steel structures, the requirements for surface treatment of the substrate are ...
