Water-based anti-corrosion paint

Abstract

The invention discloses a water-based anti-corrosion paint. The water-based anti-corrosion paint is characterized by comprising the following components: bisphenol A / F type epoxy resin, polyamidoamine, calcium borate silicates, titanium dioxide, barium sulfate, mica and deionized water, wherein calcium borate silicate powder is prepared by the steps of mixing calcium carbonate, silicon dioxide and boric acid for 24 hours according to the mass ratio of 4:5:1, melting in a platinum crucible at 1350-1500 DEG C for 0.5-2 hours, pouring in deionized water for quenching into calcium borate silicates fragments, grinding by an ultrasonic grinder and sieving with a 100 meshes sieve to obtain the calcium borate silicate powder. Due to adoption of the technical scheme, the environment pollution caused by zinc and phosphate in the existing anti-corrosion paint can be effectively solved, and the anti-corrosion agent can achieve an anti-corrosion effect on three aspects including physics, chemistry and electrochemistry.

Description

technical field [0001] The invention relates to an anticorrosion coating, in particular to a water-based anticorrosion coating. Background technique [0002] Since water-based coatings have the advantages of low VOC content, no odor, non-combustibility, and low toxicity, there is a tendency to gradually replace organic solvent-based coatings. However, water-based coatings also have high conductivity, which is easy to corrode metals and dry the coating film. Flash rust problems are prone to occur during the process. Therefore, for water-based paints for metals, it is mostly necessary to add rust inhibitors. [0003] In order to achieve a good anti-corrosion effect, the traditional method is to add anti-corrosion agents, such as red lead, lead powder, and chromates of zinc, barium, and lead, to the paint. The paint prepared from these pigments has good corrosion resistance and is an effective anti-corrosion material. However, these additives are poisonous in themselves, pos...

Problems solved by technology

The phosphate in it will cause eutrophication of the water body, lead to excessive algae reproduction, cause a drop in dissolved oxygen content in the water, deteriorate water quality, and degrade the lake, seriously destroying the ecological environment of the water body, threatening the survival of aquatic organisms and human health, and excessive phosphorus It will affect the marine environment and cause red tides

Therefore, anti-corrosion coatings rich in phosphate have caused serious pollution to the environment
