Abstract

The invention discloses low-viscosity steel structure anticorrosive paint and a construction process thereof. The low-viscosity steel structure anticorrosive paint is prepared from the following components in parts by mass: components a and b, the component a comprises the following components in parts by weight: 80-100 parts of waterborne hydroxyl acrylic acid, 1.5-2.5 parts of a dispersing agent, 0.6-1.5 parts of a defoaming agent, 0.8-2 parts of an anticorrosive bactericide, 5-7 parts of cellulose, 38-42 parts of titanium dioxide, 0.4-0.9 part of a coalescing agent and 18-24 parts of deionized water; and the component b comprises 20-24 parts of isocyanate, 15-20 parts of propylene glycol methyl ether acetate and 0.2-0.5 part of tartaric acid; the construction process of the low-viscosity steel structure anticorrosive paint comprises the following steps: step 1, cleaning the surface of a steel structure; step 2, stirring, diluting and curing; and step 3, brushing. The low-viscosity steel structure anticorrosive paint is a double-component polyurethane anti-rust primer and takes water as a solvent, so that the low-viscosity steel structure anticorrosive paint has a long-term efficient rust-proof and anti-corrosion capability, good flexibility and impact resistance, low construction viscosity and low VOC (volatile organic compound) content.

Description

technical field [0001] The invention relates to the technical field of steel structure anticorrosion, in particular to a low-viscosity steel structure anticorrosion paint and its construction technology. Background technique [0002] Steel structures have the advantages of high strength, light weight, easy fabrication and installation, and fast construction. The usage in the industrial construction industry is increasing year by year. However, there are problems of corrosion and protection in the steel structure industry. Generally, steel structures are most commonly protected by paint for rust prevention. Before the existing anti-corrosion paint is coated, the surface treatment of the steel structure is generally carried out to remove the rust on the surface of the steel structure. The surface treatment of the steel structure generally includes wire brushing or sandblasting to remove rust and oil , Water removal and other surface treatment processes, the process treatment p...
