Abstract
The invention discloses a water-based anti-rust thiourea coating which comprises the following compositions in percentage by mass: 7-9% of titanium dioxide, 0.4-0.6% of thiourea, 0.3-0.5% organic siloxane, 0.05-0.25% of alkali dissolved thickener, 1-3% diphenyl ether of ethanol, 2-4% of butanediol, 0.3-0.5% of carboxylic acid, 6-8% of aluminium phosphate, 1-3% of zinc oxide, 8-10% talc powder, 40-50% acrylic resin emulsion, 1-3% of film-forming additive, 0.3-0.5% dispersing agent and the balance of deionized water. The coating has the characteristics of water solubility and film formation at room temperature, can be isolated from oxygen and water vapor in the air and has excellent rust and corrosion resistance.
Description
Technical field
The present invention relates to the water-borne coatings field, specifically is a kind of thiocarbamide rust proof paint.
Background technology
The rust proof paint great majority of domestic production are solvent based coating, and its solvent includes iron red alcohol acid, iron oxide red phenolic aldehyde, iron oxide red epoxy ester, iron oxide red epoxy, chlorosulfonated polyethylene.The disadvantage of these coating is that price is very expensive, and contaminate environment is inflammable and harmful.In the coating material production process,, must have solvent evaporates in atmosphere owing to contain a large amount of organic solvents.The tradition rust proof paint contains heavy metallic salts such as lead, chromium, zinc, as improper use, also can pollute environment.In the coating application, particularly in the coating baking-curing process, there is the few hundred thousand tonnes of organic solvent to evaporate in the atmosphere serious environment pollution.
Water-borne coatings or be called water-based paint is as the term suggests be exactly to be the coating that solvent or dispersion medium are made with water.It mainly comprises water soluble paint and water latex paint two classes.Its maximum characteristics are that whole or most of waters have replaced organic solvent, and filmogen is dispersed or dissolved in the water by different way uniformly, have the water-fast and physicals of similar solvent based coating at dry or curing back paint film.The maximum characteristics of water-borne coatings are to be primary solvent with water, have not only reduced production cost, significantly reduce the profit environmental pollution, and have fire prevention, are easy to transportation and characteristics such as storage, and therefore wide application prospect is arranged.
Summary of the invention
The objective of the invention is at above-mentioned deficiency of the prior art, provide a kind of and have characteristics water-soluble, room temperature film-forming, but oxygen in the secluding air and steam have the environment-friendly antirust coating of remarkable antirust function of prevent erosion.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of thiocarbamide aqueous rust-proof coatings comprises according to mass percent, thiocarbamide 0.4-0.6%, organo-siloxane 0.3-0.5%, the molten thickening material 0.05-0.25% of alkali, two phenylethyl alcohol butyl ether 1-3%, butyleneglycol 2-4%, carboxylic acid 0.3-0.5%, aluminum phosphate 6-8%, zinc oxide 1-3%, titanium dioxide 7-9%, talcum powder 8-10%, CALCIUM ACRYLATE emulsion 40-50%, film coalescence aid 1-3%, dispersion agent 0.3-0.5%, balance of deionized water.
The molten thickening material of described alkali is selected from a kind of among RM-8W, the WT-105A or their mixture.
Described film coalescence aid is selected from a kind of in alcohol ester-12, the ethylene glycol methyl-n-butyl ether or their mixture.
Described dispersion agent is selected from a kind of among P-19, the SN5040 or their mixture.
Thiocarbamide aqueous rust-proof coatings of the present invention contains resin and activated feedstock calcium monofluorophosphate; active iron rust is lost activity, iron rust is separated to be enclosed in film, make deleterious iron rust be converted into useful protective layer; firmly, form persistent rustproof layer attached to the metallic surface.
Compared with prior art, the invention has the beneficial effects as follows: this coating has characteristics water-soluble, room temperature film-forming, but oxygen in the secluding air and steam have remarkable antirust function of prevent erosion.
