Abstract

The invention discloses an anti-rust coating. The coating is prepared from the following compositions in percentage by weight (wt.%): 0.4-0.6% of Tetrachloroisophthalonitrile, 0.3-0.5% of organo-silicone, 0.05-0.25% of alkali-soluble thickener, 1-3% of ethanol diphenyl ether, 2-4% of butanediol, 0.3-0.5% of carboxylic acid, 6-8% of aluminum phosphate, 1-3% of zinc oxide, 7-9% of titanium dioxide, 8-10% of talc, 40-50% of acrylic resin emulsion, 1-3% of film forming additive, 0.3-0.5% of dispersant and the balance of deionized water. The anti-rust paint has the advantages of faster speed of surface drying, long time of anti-rust, high hardness, high gloss and weather resistance, can meet the needs of automated assembly line production of large tubular or shaped materials like petroleum steel pipes and the needs of long anti-rust storage period in the open air.

Description

A kind of rust proof paint

Technical field

The present invention relates to paint field, especially a kind of industrial rust proof paint.

Background technology

At present, the rust proof paint of domestic production great majority 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.Its rust-stabilising pigment component is generally the chromic salt of red lead, lead powder and zinc, lead or barium.These pigment all have very strong toxicity, can serious environment pollutions in the production of coating and use, and healthy with the constructing operation personnel produced in infringement.Therefore, many countries have all banned use of by legislation and have contained red lead, lead powder etc. and be the coating material production and the use of rust-stabilising pigment component.

People successively develop the rust proof paint with rust-stabilising pigment components such as zinc phosphate, aluminum phosphate, zinc molybdate, lime borates, and these coating have the low characteristics of toxicity, but rust-proof effect is bad, and the color development of film-forming resin and stability are not good enough yet.

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, a kind of environment-friendly antirust coating with long, advantages such as hardness is high, gloss is high, good weatherability of fast, antirust time of surface drying speed is provided.

For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:

A kind of rust proof paint comprises according to mass percent, daconil M 0.4-0.6wt.%, organo-siloxane 0.3-0.5wt.%, the molten thickening material 0.05-0.25wt.% of alkali, two phenylethyl alcohol butyl ether 1-3wt.%, butyleneglycol 2-4wt.%, carboxylic acid 0.3-0.5wt.%, aluminum phosphate 6-8wt.%, zinc oxide 1-3wt.%, titanium dioxide 7-9wt.%, talcum powder 8-10wt.%, CALCIUM ACRYLATE emulsion 40-50wt.%, film coalescence aid 1-3wt.%, dispersion agent 0.3-0.5wt.%, 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 12 carbon alcohol esters, 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.

Rust proof paint of the present invention contains resin and activated feedstock calcium monofluorophosphate, and active iron rust is lost activity, and iron rust is separated to be enclosed in film, and makes deleterious iron rust be converted into useful protective layer, firmly attached to the metallic surface, forms persistent rustproof layer.

Compared with prior art, the invention has the beneficial effects as follows: rust proof paint of the present invention has long, advantages such as hardness is high, gloss is high, good weatherability of fast, antirust time of surface drying speed.Can satisfy large pipe or production of section bar automatic assembly line and the antirust needs of long-term outdoor storage such as petroleum steel pipe.
