Abstract

The invention provides waterborne rusted paint, which mainly comprises transforming agent, transformation accelerator, water, film-forming additives, freeze-thaw stabilizer, ethylene-propylene emulsion, thickener, defoamer and preservatives. The invention also provides a method for preparing the waterborne rusted paint. The waterborne rusted paint has the characteristics of low film-forming temperature, good storage stability, good film properties, high film water resistance and the like, and completely meets the antirust protection requirements of the shipbuilding industry, petroleum industry, machinery industry, construction industry and other various industries needing steel antirust protection.

Description

A kind of waterborne rusted paint and preparation method thereof
Technical field
The present invention relates to a kind of waterborne rusted paint that is used for steel and iron member and preparation method thereof.
Background technology
In order to protect the steel and iron member non-corrosive, often adopt the method for coating.Before using coating, must thoroughly eliminate rust to base material, the labour intensity of rust cleaning work is very big in the past, and concerning large-scale and baroque steel and iron member, thoroughly rust cleaning almost is impossible comprehensively.
On rust paint has been arranged at present, and it need not thorough rust cleaning before using, and can receive antirust effect equally directly on the rust face of steel and iron member.The spy opens and has narrated a kind of anti-corrosive paints of being made up of emulsion, film coalescence aid, transforming agent, inversion accelerating agent, freeze-thaw stabiliser, defoamer, tackifier and water etc. in clear 57-18766 and the GB2160877 patent, and this is a class waterborne rusted paint preferably at present.But the shortcoming that also also has film-forming temperature height, package stability difference.
Summary of the invention
The objective of the invention is to: the object of the present invention is to provide a kind of waterborne rusted paint, more definite theory provides a kind of film-forming temperature low, and storage stability is good, not the transformant waterborne rusted paint of phosphoric acid.
Another object of the present invention is to provide a kind of preparation method of the present invention.
The object of the present invention is achieved like this:
A kind of waterborne rusted paint, in weight percentage, this system component is:
Vinyl acetate emulsion 60~75%
Transforming agent 3~10%
Inversion accelerating agent 1~5%
Thickening material 5~10%
Film coalescence aid 1~5%
Freeze-thaw stabiliser 2~3%
Defoamer 0.5~1%
Sanitas 0.5~1%
Water all the other;
Described vinyl acetate emulsion is the vinyl-acetic ester-acrylic ester emulsion by step polymerization synthetic nucleocapsid structure;
Described transforming agent is selected from tannic acid or gallic acid;
Described inversion accelerating agent is selected from pyrocatechol or benzenetriol;
Described thickening material is selected from Walocel MT 20.000PV, exquisite agar, alginates or polyacrylate;
Described film coalescence aid is selected from ethylene glycol ethyl ether or butyl glycol ether;
Described freeze-thaw stabiliser is selected from ethylene glycol, 1,2-propylene glycol or hexylene glycol;
Described defoamer is selected from tributyl phosphate or water-based silicone oil;
Described sanitas is selected from Sodium Benzoate or Sodium Nitrite.
The present invention adopts the synthetic vinyl acetate emulsion with laminate structure particle of distribution polymerization method, so-called laminate structure emulsion, be exactly by the different polymkeric substance of two or more components, being not, homogeneous phase is present among the same particle, with a kind of polymkeric substance is core, another kind of polymkeric substance also wraps in core outer layer, so, also claim core-shell emulsion.With the coating of this emulsion preparation, have following advantage: one, make rigid polymer be in the center, soft polymer wraps in the outside, helps particle like this and is melting, and helps the surface bonding of coated article or adheres to.And film-forming temperature is low, after the film forming, can obtain the hardness height simultaneously, the filming of good combination property; Its two, make the polymkeric substance that is difficult for dispersive wetting ability difference occupy the center, the polymkeric substance that hydrophilicity is strong wraps in the periphery, can improve the dispersion stabilization of emulsion.After the film forming, present hydrophobicity again, therefore can improve the water tolerance of filming.
The present invention also provides a kind of preparation method of waterborne rusted paint of the present invention, may further comprise the steps:
A) emulsion preparation: adopt the synthetic vinyl-acetic ester-acrylic ester emulsion of distribution polymerization method with laminate structure particle;
B) coating preparation: after transforming agent, inversion accelerating agent, water, film coalescence aid and freeze-thaw stabiliser Hybrid Heating, be added in the vinyl-acetic ester-acrylic ester emulsion for preparing in the steps A, and then add thickening material, defoamer, sanitas successively, promptly obtain described waterborne rusted paint after stirring.
Owing to adopted technique scheme; waterborne rusted paint of the present invention has that film-forming temperature is low, package stability and characteristics such as film performance is good, water-resistance property of coating height, satisfies the corrosion protection requirement of the industry-by-industry of shipbuilding industry, petroleum industry, mechanical industry, building trade and the protection of other needs steel rust preventions fully.
