Abstract
The invention discloses a water-based residual rust paint and a preparation method thereof. The paint is prepared from the following raw materials: styrene-acrylic emulsion, montmorillonoid, a transforming agent, a transforming accelerant, a defoaming agent, a thickener, a freezing and thawing stabilizer, a dispersant, an adhesion promoter, pigment and water. The preparation method comprises the following steps: mixing the water, the montmorillonoid and the pigment, grinding the obtained mixture, adding the transforming agent and the transforming accelerant, and uniformly mixing; heating and stirring until the materials are completely dissolved; adding the mixture obtained from the former step to the styrene-acrylic emulsion drop by drop; stirring for 20-30min at room temperature; and adding the defoaming agent, the thickener, the freezing and thawing stabilizer, the dispersant and the adhesion promoter, and further stirring for 20-30min at room temperature to obtain the water-based residual rust paint. The water-based residual rust paint disclosed by the invention is non-toxic and environmental friendly, and excellent in adhesion; and the paint, by virtue of the montmorillonoid, is stronger in compactness and the corrosion resistance effect of the paint is enhanced.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of waterborne rusted paint and preparation method thereof.
Background technology
Ferrous materials corrosion both can affect the purposes of steel, also can its appearance effect of havoc greatly.Applying one deck protective layer on steel top layer can suppress steel to continue to get rusty, and first will carry out processing of rust removing thoroughly before coating protective layer.The equal Shortcomings of traditional derusting process, the serious and high in cost of production shortcoming of as large in labour intensity, chemical pollution, therefore on rust paint becomes the focus of research as novel derusting process.
On rust paint can as metal primer; only the floating rust of rust surface need be removed during use, just directly can brush the metallic surface at band rust, rust transforming agent and iron rust generation chemical reaction; generate a kind of black rete can protecting metal, thus objectionable impurities is changed into benefit materials.
Conventional belt rust coating type cardinal principle is for utilizing phosphoric acid with tannic acid for rust transformation is become tannic acid iron and iron phosphate membrane by main raw material.But along with the prolongation in reaction times, the continuous hyperplasia of iron rust, the rust transforming agent on top layer does not penetrate into rusty scale inside completely, and rust transformation effect is not good.
Chinese patent CN 102863861 A discloses a kind of waterborne rusted paint and preparation method thereof, this waterborne rusted paint is made up of the raw material of following weight proportion: Crosslinked Styrene-Acrylate Emulsion 30 ~ 40 parts, transforming agent 8 ~ 12 parts, inversion accelerating agent 8 ~ 12 parts, rust-stabilising pigment 2 ~ 3 parts, defoamer 0.5 ~ 0.8 part, film coalescence aid 0.5 ~ 0.8 part, thickening material 0.5 ~ 0.8 part, 30 ~ 40 parts, water.The waterborne rusted paint that this technical scheme obtains is in the poor adhesive force of steel surface, and anti-corrosion effects is not good.
Chinese patent CN 102850864 A discloses a kind of waterborne rusted paint, comprise following composition: benzene emulsion 30 ~ 35 weight part, yellow prussiate of potash 5 ~ 10 weight part, polyvinyl formal 3 ~ 7 weight part, zinc-chrome yellow 3 ~ 7 weight part, zinc phosphate 3 ~ 7 weight part, zinc oxide 3 ~ 7 weight part, red iron oxide 8 ~ 12 weight part, talcum powder 8 ~ 12 weight part, water 20 ~ 30 weight part.The waterborne rusted paint rust transformation efficiency that this technical scheme obtains is low, and raw material not environmentally, harmful.
Summary of the invention
Based on above-mentioned information, the object of the present invention is to provide a kind of strong adhesion, and high waterborne rusted paint of rust transformation efficiency and preparation method thereof.
Technical scheme of the present invention is as follows:
A kind of waterborne rusted paint, according to weight parts, is formed by following preparation of raw material: benzene emulsion 40 ~ 50 parts, polynite 2 ~ 10 parts, transforming agent 10 ~ 15 parts, inversion accelerating agent 6 ~ 10 parts, defoamer 1 ~ 2 part, thickening material 1 ~ 2 part, freeze-thaw stabiliser 0.5 ~ 2 part, dispersion agent 0.5 ~ 1 part, adhesion promoter 0.5 ~ 1 part, pigment 1 ~ 2 part, 40 ~ 50 parts, water.
Described transforming agent is phytic acid and/or Weibull.
Described inversion accelerating agent is pyrogallol.
Described defoamer is modified polyorganosiloxane defoamer.
Described thickening material is one or more in sodium alginate, agar-agar or Silica hydrogel.
Described freeze-thaw stabiliser is ethylene glycol and/or propyleneglycoles.
Described dispersion agent is one or more in polyacrylamide, fatty acid polyglycol ester, methyl amyl alcohol.
Described adhesion promoter is AP-3800.
Described pigment is one or more in zinc phosphate, titanium dioxide, zinc yellow or red iron oxide.
The preparation method of waterborne rusted paint, comprises the steps:
(1) by after water, polynite and pigment mixing to be ground to fineness be 30 ~ 40 microns, add transforming agent and inversion accelerating agent mixes, be heated to 60 ~ 80 DEG C, be stirred to and dissolve completely, for subsequent use;
(2) mixing solutions of heat step (1) prepared dropwise is added in benzene emulsion under the condition constantly stirred, under room temperature, stirring 20 ~ 30 minutes is continued after adding, add defoamer, thickening material, freeze-thaw stabiliser, dispersion agent and adhesion promoter, under room temperature, continue stirring 20 ~ 30 minutes equally, obtain waterborne rusted paint.
Waterborne rusted paint asepsis environment-protecting provided by the invention, has excellent sticking power, and owing to adding polynite, makes coating have stronger compactness, and anticorrosion effect strengthens.
