The Research On The Water-soluble Anti-rust Paint Of The Steel Structure

The steel structure is one of the most important structural configuration in building industry, the corrosion of the steel structure bring great damage for building industry. Water-soluble anti-rust paint is one of the most enconomical and sound way in the steel structural corrosion, people increasingly pay attention to the environment problem, Water-soluble anti-rust paint avoid the pollution of solvent volatilization.This text with the reserch excellence water-sulble anti-rust for purpose, carried on thorough analysis to protection function and mechanism of anti-rust paint, and analyzed the function mechanism of water-sulble anti-rust paint; Elaborated the formula design process in the meantime of the anti-rust paint , pass to original the analysis of the material function, chose suitable paint and auxiliary, to become film material, inhibitor and film forming auxiliary to carry on to experiment analysis and choose; And pass to experiment certain reasonable of creation craft;In addition studied original materialdosage quantity of the influence of the variety upon the coating function, and made sure the formula of the paint, end and existing paint carried on contrast.Experiment result enunciation, water-sulble anti-rust paint mainly is depend on dope in resin of the alacrity harmful composition in reaction regiment, live pigment or rust conversion and rust layer respond, born stablely repress compound, but have protection function; The dope develop since have conversion characteristic, also have stable characteristic; It concrete formula is:Benzene resin is 30-40%, iron oxide is 2-3%, frencu chalk is 8-10%, zinc phosphate is 2.5-3.0%, zinc orin is 1.5-2.0, aluminium hydroxide is 1.0%, phosphoric acid is 18.5-19.5%, tannin is 5.5-6.0%, zinc dihydric phosphate is 0.075-0.1875, potassium dichromate is 0.125-0.3125%, film forming auxiliary is 2-3%, dibutyl phthalate is 1.35-1.45%. Its creation craft is simple and convenient. Compared with the existing coating, the coating function make is excellent, at first material easily get, the cost is low, can be coated on the surface of substrate with 90μm rust, without pretreatment. It can react with rust, and make it into stable chelate. Thus it can transfer the active rust into inert covering, so as to protect the steel instrutments. Since can used to a bottom paint, can also used to a noodles paint, and dry quick, the construction is convenient.
