Abstract
The invention relates to a water-based antirust paint prepared from nanometer slurry. The water-based antirust paint consists of the following compositions in percentage by weight: 3 to 8 percent of water-based nanometer slurry, 0.3 to 0.8 percent of a surfactant, 0.5 to 1 percent of a dispersant, 0.2 to 0.6 percent of a defoaming agent, 0.5 to 1 percent of an anti flash-rust additive, 0.08 to 0.2 percent of a chloric ketone disinfector, 1.0 to 1.6 percent of propanediol, 10 to 15 percent of compound ferrotitanium powder, 10 to 15 percent of iron oxide red powder, 1 to 3 percent of magnesium hydroxide potassium titanate whiskers , 2 to 6 percent of mica powder, 5 to 10 percent of talcum powder, 12 to 20 percent of polyacrylic emulsion, 12 to 20 percent of water-based acrylic resin, and the like, and the balance being deionized water. The water-based antirust paint has the advantages that the paint has innocuity, harmlessness, safety, and environmental protection; the excellent antirust performance of the paint exceeds that of alcohol acid red lead rust-proof paint; through detection of an authoritative institution, the capacity for brine resistant of the water-based antirust paintreaches over 500 hours; and the price of the water-based antirust paint is relatively reasonable.
Description
Technical field
The present invention relates to technical field of coatings, the waterborne anti-rust lacquer that a kind of specifically applying nano slurry is made.
Background technology
Along with the continuous development of science and technology and social productive forces, human environmental issue receives publicity in worldwide to living environment also pay attention to day by day, and environment protection has become the universe's common task.
In the coatings industry, most of organic coatings have all used some to human body and the deleterious starting material of environment in process of production, in production process and construction process, can give off deleterious waste water and waste gas, even in for some time after construction, also can discharge obnoxious flavour.For example, use at present in traditional solvent-borne type rust-inhibiting paint, contain toluene, dimethylbenzene and make siccative, because the popularity of its application will be brought great harm to workmen's health and environment with heavy metal lead, cobalt, manganese.
In recent years, domestic scientific research personnel develops many waterborne anti-rust lacquers in succession, but can not get the approval in market, and its major cause is: the stability problem of water-borne coatings; With the water-base resin or the emulsion of top grade, rustless property has improved, but costs an arm and a leg; With general water-base resin or emulsion, price is relatively cheap, but rustless property is relatively poor.
Summary of the invention
The objective of the invention is to develop the waterborne anti-rust lacquer that the applying nano slurry of a kind of nontoxic, harmless, safety, environmental protection is made.
The waterborne anti-rust lacquer that a kind of applying nano slurry of the present invention is made is made of following constituent and weight percent: waterborne nano slurry 3%-8%; Tensio-active agent 0.3%-0.8%; Dispersion agent 0.5%-1%, defoamer 0.2%-0.6%, the anti-rust agent 0.5%-1% that dodges; The chloride ketone microbial inoculum 0.08%-0.2% that disappears, propylene glycol 1.0%-1.6%, composite iron-titanium powder 10%-15%, ferric oxide red powder 10%-15%, magnesium hydroxide potassium titanate crystal whisker 1%-3%, mica powder 2%-6%, talcum powder 5%-10%, ACRYLIC EMULSION 12%-20%, water-and acrylate 12%-20%, alcohol ester 12 film coalescence aid 0.8%-1.2%, dimethylethanolamine neutralizing agent 0.2%-0.5%, AF-288 rheological agent 0.8%-1%, surplus is a deionized water.
Waterborne nano slurry is to be raw material with the natural accumulation supporting stone breeze, after selected, add in the deionized water by a certain percentage, with natural accumulation supporting stone sodium baseization, with fluorocarbon surfactant and compound quaternary ammonium salt it is carried out intercalation modifying more earlier, make the organic ammonium positively charged ion enter the rectorite leng interlayer, and interlamellar spacing is strutted to 4.75nm by 2.41nm, even peel off, making water paste with nano level rectorite leng lamella, its solid content is 10%; The rectorite leng waterborne nano slurry can play good modifying function to water-borne coatings, and performances such as ADHESION OF PAINTS power, impact resistance, snappiness, hardness are significantly improved.
Tensio-active agent is the tensio-active agent of fluorine silicon class, is specially perfluoro capryl tetraethyl-amine salt C

Dispersion agent is water soluble paint dispersion agent TC-AT, and there is sale in Anhui Tai Chang chemical industry company limited.This product is chelating titanate, and is water-soluble, is a kind of novel dispersant in the coatings industry.Except can making the convenient not sagging of coating application; Also can improve repellency, the wear resistance of paint film.
Defoamer can be the coating dedicated defoamer BX-825 that Shanghai Boyihe Chemical Industry Co., Ltd. produces, and also can be that Changzhou is newly pacified the waterborne general defoamer Df380 defoamer that defoamer factory produces.The coating dedicated defoamer BX-825 that Shanghai Boyihe Chemical Industry Co., Ltd. produces is that a kind of non-ionic type does not contain organosilyl compound defoamer, and froth breaking is rapid; Nontoxic, odorlessness; Rate of drying is fast, auxiliary good film-forming property; Owing to contain multiple fine antifoam composition, thereby widely applicable, be specially adapted to eliminate the foam of systems such as styrene-acrylic latex, ethylene propylene rubber latex, pure third latex, vinyl acetate between to for plastic latex.Changzhou is newly pacified the froth breaking that waterborne general defoamer Df380 defoamer that defoamer factory produces is fit to the hydrophobicity exterior coating etc. of aqueous architectural coating, industrial coating, water-base resin coating, phenylpropyl alcohol, second third, pure third, Vinyl Acetate Copolymer copolymer emulsion.
The anti-rust agent CHO7A that dodges, Shuande, Foshan City head of district sky trade Co., Ltd is on sale, is a kind of colourless liquid, and the water-borne coatings that does not contain nitrite prevents dodging the rust agent; CHO7A can stop the surface of ferrous metal ground that the negative electrode reaction takes place, and can also stop the ionization of iron, thereby avoids iron by the oxidation of airborne oxygen institute.
The AF-288 rheological agent is that Zhejiang Province produces along inspiring confidence in clay chemical industry company limited, has advantages such as thixotropy is strong, easily disperse, stability, economy.
The composite iron-titanium powder rust-stabilising pigment is the product that Wanda (Wuxi) scientific ﹠ technical corporation produces, and rustless property is outstanding, and annual sales is more than 6000 tons.
The advantage of the waterborne anti-rust lacquer that a kind of applying nano slurry of the present invention is made is: nontoxic, harmless, safety, environmental protection; Rustless property is good, surpasses the alkyd red lead paint; Detect through authoritative institution, its salt water resistance ability reached more than 500 hours; Price is relatively reasonable.
