Steel bridge waterproof anticorrosive paint

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a steel bridge waterproof anticorrosive paint, which is prepared from the following components in parts by mass: 20-40 parts of epoxy resin, 60-80 parts of ethylene glycol, 20-40 parts of nitrilotriethanolamine, 20-30 parts of diatomite, 2-8 parts of trimethylolpropane, 1-5 parts of diphenylmethane diisocyanate,1-6 parts of nanoscale titanium dioxide, 2-10 parts of tea polyphenol, 2-10 parts of propolis and 2-5 parts of clove oil. The tea polyphenol, propolis and clove oil are added into the beneficial smallfruit trees, so that the preservative and antibacterial functions are good.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a waterproof and anti-corrosion coating for steel bridges. Background technique [0002] Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. The corrosion of metals spreads all over the national economy and brings huge losses to the national economy. In industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total output value of the national economy, the annual corroded and rusted steel accounts for about 20% of the output, and about 30% of the equipment is scrapped due to corrosion. In China, the economic loss caused by metal corrosion is as high as more than 30 billion yuan per year, accounting for 4% of the gross national product. For a long time, people have used a variety of techniques to protect metals from corrosion. Among them, one of the most...

Problems solved by technology

Among them, one of the most effective and commonly used methods for metal equipment anti-corrosion is to apply an anti-corrosion coating on the metal surface to isolate the corrosive medium from the metal substrate. There are still deficiencies in strength and other aspects, and it is difficult to meet the high-quality or anti-corrosion requirements in harsh environments
