Abstract

The invention relates to an acid-resistant double anti-rust coating which is prepared from the following components in percentage by weight: 31-31.6% of water, 0.8-1% of a dispersant, 0.03-0.07% of a wetting agent, 0.5-0.7% of an adhesive force accelerant, 0.08-0.12% of a sterilizing agent, 18-23% of exterior wall finish, 33-35% of an emulsion, 4.8-5% of a mill base, 0.08-0.12% of a defoaming agent, 3.5-4.5% of aluminum triphosphate, 1-1.4% of butyl cellosolve and 0.7-0.9% of a film-forming agent. The invention aims to provide the acid-resistant double anti-rust coating which has an extremely good adhesive force and good anti-rust effect, further has a double anti-rust function and can be directly applied to any metal surfaces.

Description

A kind of antiacid dual rust proof paint

Technical field the present invention relates to a kind of coating, and particularly a kind of aqueous rust-proof coatings, belongs to technical field of chemical paint.

Background technology rusty stain is a global problem, and the outer space also can find its trace even.The thinner that traditional rust-inhibiting paint adopts is volatile organic solvent, and to help to form film, this kind of organic solvent, not only wastes resource, contaminate environment, brings danger also to production and construction site.In addition this paint must remove the rusty stain of metallic surface before construction, time-consuming and poor effect.

Summary of the invention the object of this invention is to provide a kind of antiacid dual rust proof paint, and this rust proof paint has fabulous sticking power, favorable rust preventing effect, also has dual antirust function, can directly be applied to any metallic surface.

The antiacid dual rust proof paint of one of the present invention count by weight percentage into:

Water: 31-31.6%; Dispersion agent: 0.8-1%; Wetting agent: 0.03-0.07%; Adhesion promoter: 0.5-0.7%; Sterilant: 0.08-0.12%; Exterior wall paint: 18-23%; Emulsion: 33-35%; Mill base: 4.8-5%; Defoamer: 0.08-0.12%; Aluminium triphosphate: 3.5-4.5%; Butyl glycol ether: 1-1.4%; Film forming: 0.7-0.9%.

The dispersion agent that the present invention uses is low molecular weight sodium polyacrylate dipersant, concentration and the stability thereof of fillers dispersed slurry can be significantly improved, by this dispersion agent, a layer charge can be surrounded on filler particles surface, make mutually to repel between particle, thus reach the effect of stable slurry.

Aluminium triphosphate used in the present invention, is applicable to various water soluble resin coating, can be applicable on rust paint.Feature is based on aluminium triphosphate, through special modification and surface treatment, can improve the novel antirust pigment of rustless property, can replace poisonous dyestuff.Be just assert the non-harmful white rust-stabilising pigment of series in the world, nontoxic, nuisanceless, antiseptic and rustproof respond well, various water-soluble normal temperature type is dried resin-made and to be got everything ready the acidproof of superior rustless property, water-fast, salt water resistance heavy duty system.Due to " dual antirust " function of aluminium triphosphate, to the corrosion of the metal objects such as iron, there is extremely strong restraining effect.

The adhesion promoter that the present invention uses is a kind of not containing the nonionic compound of silicone, effectively can improve the tack of the metallic surface to difficulty attachment, and not affect the weathering resistance of film, can high-temperature baking resistant and not impact effect.

The exterior wall paint that the present invention uses is the senior exterior wall paint that our company produces, and plays a part to improve opacifying power in system.

One embodiment of the present of invention below embodiment.

A kind of antiacid dual rust proof paint, its content is as follows:

31.3 part deionized water; 0.9 part of dispersion agent; 0.6 part of adhesion promoter; 0.05 part of wetting agent; 0.1 part of sterilant; 20 wall paintes especially; 36 parts of emulsions; 4.96 parts of dark green mill bases of phthalein; 0.1 part of defoamer; 4 parts of aluminium triphosphates; 1.2 parts of butyl glycol ethers; Film forming: 0.7-0.9%.

According to the aqueous rust-proof coatings favorable rust preventing effect that the present invention makes, this rust proof paint has excellent water-fast, acidproof, Corrosion Protection, and favorable rust preventing effect, also has dual antirust function.

Claims (2)

1. the antiacid dual rust proof paint of one of the present invention count by weight percentage into:

Water: 31-31.6%; Dispersion agent: 0.8-1%; Wetting agent: 0.03-0.07%; Adhesion promoter: 0.5-0.7%; Sterilant: 0.08-0.12%; Exterior wall paint: 18-23%; Emulsion: 33-35%; Mill base: 4.8-5%; Defoamer: 0.08-0.12%; Aluminium triphosphate: 3.5-4.5%; Butyl glycol ether: 1-1.4%; Film forming: 0.7-0.9%.

2. the antiacid dual rust proof paint of one according to claim 1, is characterized in that " dual antirust " function of said aluminium triphosphate, has extremely strong restraining effect to the corrosion of the metal objects such as iron.
