Superfine composite vanadium-titanium antirust coating and preparation method thereof

Abstract

The invention provides a superfine composite vanadium-titanium antirust coating and a preparation method thereof. The superfine composite vanadium-titanium antirust coating is prepared from the following components in parts by weight: 20-400 parts of water-based emulsion and / or water-based resin, 0-40 parts of a dispersing agent, 0.5-10 parts of a drier, 2-10 parts of a neutralizer, 5-15 parts of an additive, 80-300 parts of filler, 80-400 parts of antirust powder, 10-30 parts of toner and 300-400 parts of a solvent. The superfine composite vanadium-titanium antirust coating has good flash rust resistance, has a good corrosion inhibition effect, can assist in improving the later salt spray resistance, has good adhesion, pencil hardness, water resistance, paint film flexibility, storage stability and the like, is short in surface drying time and hard drying time, and improves the construction efficiency; the raw material cost is low.

Description

technical field [0001] The invention relates to the technical field of antirust products, in particular to an ultrafine composite vanadium-titanium antirust coating and a preparation method thereof. Background technique [0002] Oil stains and bacteria on the surface of metal products will accelerate the corrosion of metal. According to statistics, the annual economic loss caused by metal corrosion in the world is as high as 700 billion U.S. dollars, which is higher than the losses caused by any kind of natural disaster. coated or impregnated with anti-rust paint. In 2002, the total output of China's antirust coatings was 530,000 tons, of which industrial antirust coatings produced 250,000 tons, with sales of 5 billion yuan; ship coatings produced 160,000 tons, with sales of 3 billion yuan; container coatings were 120,000 tons, with sales 2.2 billion. [0003] Traditional water-based coatings have low hardness, poor salt spray resistance and aging resistance of the paint f...

AI Technical Summary

Problems solved by technology

The types of anti-rust coatings mainly include inorganic zinc-rich primers, polyurethane coatings, alkyd resin anti-rust coatings, etc. The zinc-rich coatings made of zinc-rich coatings have high zinc content, which increases the preparation cost; polyurethane coatings are made of polyurethane resin as the base material and pigments, fillers, etc. as auxiliary materials, and are more adaptable to various construction environments and objects. Strong, can be cured at low temperature, can be applied in a humid environment and on a wet substrate, and has outstanding oil resistance, but it has greater irritation and toxicity; the alkyd resin in the alkyd resin antirust coating itself has no Anti-rust performance, but the price is low. The preparation of anti-rust coatings mainly depends on anti-rust pigments, such as red lead, iron red, zinc phosphate, etc., but the performance is difficult to meet the general atmospheric anti-rust requirements. Among them, alkyd red moon anti-rust Rust paint is highly toxic, environmental protection, and construction methods are greatly restricted

[0004] With the progress of industrialization and social progress, people have higher and higher requirements for anti-rust coatings. The existing water-based anti-rust coatings dry slowly and have general salt water resistance; although acrylic emulsion coatings have good weather resistance, Water resistance and chemical resistance, but it is easy to cause hot sticking and cold brittleness, anti-sticking property and poor heat resistance. The shortcomings of the above two coatings make the coating not achieve the corresponding effect and cannot meet the needs of specific customers. create a void in the market
