Anti-bubbling steel structure protective coating

Abstract

The invention provides an anti-bubbling steel structure protective coating. The anti-bubbling steel structure protective coating is characterized by being prepared from, by mass, 60-90 parts of acrylic emulsion, 16-25 parts of sodium propionate, 6-10 parts of pentaerythritol, 1-4 parts of zinc borate, 2-6 parts of barium sulfate, 0.3-0.8 part of flatting agent and 15-25 parts of acetone. Zinc borate and barium sulfate are fully smashed and then added into mixed liquid prepared from the acrylic emulsion, sodium propionate, pentaerythritol and acetone, zinc borate, barium sulfate and the flatting agent are added for high-speed homogeneous dispersion, the air drying performance obtained after painting of the coating is optimized, and the formula is scientific; a coat is dense and high in smoothness after a steel structure is subjected to anticorrosion painting, the hardness of the coat is improved, and good adhesive capacity is achieved; local rusting and bubbling are not likely to happen, the service life of the coat is prolonged, and the protective effect on the steel structure is improved.

Description

technical field [0001] The invention relates to a coating, in particular to an anti-foaming steel structure protective coating, which belongs to the technical field of protective coatings. Background technique [0002] At present, steel structures are more and more widely used in construction, machinery and other fields. Steel structures have the advantages of easy forming, mass production, and convenient installation. Steel structures can partially replace brick and concrete structures in the construction field. Large-scale factories also use steel structures. structure. Steel structures will corrode in natural environments such as humidity, and need to be painted with anti-corrosion and anti-rust paints. However, the existing steel structure paints have simple formulas and poor adhesion to the steel surface. After a long time, they are prone to damage and local corrosion, forming Foaming affects the service life of the steel structure itself. [0003] For example, the Ch...

Problems solved by technology

[0004] The purpose of the present invention is to solve the defects and deficiencies of the existing coatings for steel structures, such as simple formula, poor adhesion to the steel surface, easy local corrosion and foaming after a long time, poor anti-corrosion effect, and short service life. Provide a kind of anti-foaming steel structure protective coating with scientific formula, good adhesion, not easy to local corrosion and blistering, and prolong service life
