Abstract
The invention provides a styrene-acrylic emulsion aqueous rust coating which comprises the components by weight percentage as follows: 35% of styrene-acrylic emulsion (40% of solid content), 4% of transforming agent, 12% of iron oxide red, 3% of zinc dihydrogen phosphate, 6% of zinc yellow, 5% of zinc oxide, 6% of talcum powder, 5% of barium sulfate and 40% of water. The styrene-acrylic emulsion aqueous rust coating provided by the invention has the advantages that the coating can be used without surface treatment and directly applied to a rusty steel product, so that a solid protective film is formed on the steel surface, the acid and alkali resistance properties are excellent, oxygen and steam are prevented from leaking, and the anti-rust effect is greatly higher than that of current anti-rust coatings.
Description
Technical field
The present invention relates to technical field of coatings, refer in particular to a kind of benzene emulsion waterborne rusted paint.
Background technology
Because steel construction has intensity height, good toughness, easy to make, the series of advantages such as speed of application is fast, building cycle is short, and obtains using more and more widely in modern architecture.But it holds corrosion-prone characteristics and has but brought huge loss to national economy, the anticorrosion with painting coating operation that is absolutely necessary.Its effect is the rete that forms one deck compact structure at substrate surface, base material and atmosphere are separated, to prevent corrosion, still because substrate surface exists its oxide compound or other compound and impurity, before using coating, must be to the base material decontamination that thoroughly eliminates rust, make whole surface cleaning, and then be coated with and touch, its rust cleaning decontamination labour intensity is large, and for big machinery and baroque steel and iron member, the decontamination that comprehensively eliminates rust thoroughly almost is impossible.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of labour intensity is low, favorable rust preventing effect, cost are low, the benzene emulsion waterborne rusted paint of excellent performance.
For achieving the above object, technical scheme provided by the present invention is: a kind of benzene emulsion waterborne rusted paint, and the weight percent of described each component of coating is:
Benzene emulsion (solid content 40%) 30-40%
Transforming agent 3-6%
Iron oxide red 10-13%
Primary zinc phosphate 1-5%
Zinc yellow 3-8%
Zinc oxide 4-7%
Talcum powder 5-8%
Barium sulfate 3-8%
Water 20-60%;
The preparation method of above-mentioned prescription is:
Pigment and rust-preventive agent are added water furnishing dispersible pigment color paste, put into the ball mill ball milling, make mill base can cross 200 mesh sieves; Transforming agent is mixed with a certain proportion of aqueous solution; Place enamelled vessel to mix mill base and transforming agent solution, even with the stirrer rapid stirring; With levigate mistake 200 mesh sieves of filler, mix in the adding enamelled vessel; Add water and adjust dope viscosity to being coated with-4 glasss of 25s.
Described benzene emulsion is made of following component:
Vinylbenzene 13-17%
Vinylformic acid 2.5-4%
Butyl acrylate 16-20%
Methyl methacrylate 7-9%
Emulsifying agent 0.7-1.2%
Ammonium persulphate 0.4-0.7%
Deionized water 30-62%.
The preparation method of described benzene emulsion is: it is for subsequent use that ammonium persulphate is mixed with 5% (massfraction) aqueous solution; It is soluble in water to take by weighing the metering emulsifying agent, slowly adds mix monomer, and vigorous stirring 15～20min is until be mixed into emulsion; Emulsion with 1/5 adds reactor, adds 1/2 initiator again, stirs and is warming up to 70～72 ℃, is incubated to material to show slightly blue, is warming up to 85 ℃; Add the residue initiator, drip continuously the residue emulsion and finish in 2h, speed is as the criterion with the control temperature in the kettle; Be warming up to 90～95 ℃, insulation 1h is cooled to about 30 ℃, and adding ammoniacal liquor adjusting pH value is 8～9.
The invention has the advantages that: this coating can be constructed under the surface-treated condition not doing; coating is directly applied on the steel product of band rust; make it form a solid protective membrane at steel surface; its sour alkaline resistance properties is excellent; can prevent the infiltration of block and aqueous vapor, its rust-proof effect is much higher than existing rust proof paint.
