Description
Technical field
The present invention relates to zinc-rich paint technical field, more particularly to a kind of corrosion-resistant antirust steel structure surface treatment water
Property potassium silicate zinc rich primer and preparation method thereof.
Background technology
Zinc rich primer is the class anticorrosive paint product using the zinc powder acted on sacrificial anode as main rust resisting pigment,
There is cathodic protection to act on steel substrate, steamer, offshore production platform, container, harbour, lock are widely used in for a long time
The protection of door, storage tank, pipeline and bridge etc..It is conventional at present it is main have epoxy zinc rich primer, alcohol-soluble zinc-rich coating and
Waterborne inorganic einc-rich primer.
Waterborne inorganic einc-rich primer be with water as solvent, silicate（Including potassium silicate, sodium metasilicate, lithium metasilicate etc.）It is film forming
Base fluid（Binder）, zinc powder for pigment anticorrosive paint.Zinc powder generates the zinc silicate of network structure with silicate reaction, while
Zinc silicate iron complex also is formd in metal surface with steel reaction, thus the stronger chemistry of bond energy is formed in steel surface and inhaled
It is attached.And the adhesive force of epoxy zinc rich primer from resin to the cohesive force of steel surface, belong to physical absorption.Inorganic matter is more organic
Thing conducts electricity very well, therefore the cathodic protection effect of zinc powder is relatively strong, and the corrosion resistance of waterborne inorganic einc-rich primer is far superior to have
Machine zinc-rich coating, but equally also there is the common fault of inorganic coating, such as film is more crisp easy to crack, and adhesive force is not strong, and decorative effect is not
It is good etc., and pliability is preferable after organic material film forming, therefore some water-soluble breasts can be added in waterborne inorganic einc-rich primer
Liquid makes organic matter be filled in improve the pliability of coating in "-Si-O-Si-" network structure as auxiliary film forming matter, than
Such as document《Study on the modification of the styrene-acrylic emulsion to zinc-rich coating》Just changed as modifying agent is prepared for a kind of styrene-acrylic emulsion with styrene-acrylic emulsion
The aqueous inorganic zinc-enriched coating of property.
But only be have been introduced to styrene-acrylic emulsion addition and to the pliability of coating in document, with production technology and
Continuing to optimize for formula, finds flake zinc powder compared with spherical zinc powder in covering power, floating capacity and advantage in terms of screening ability
It is prominent, thus flake zinc powder is increasingly becoming zinc-rich paint first-selection filler, but it is living in aqueous inorganic silicate alkalescence coating
The too strong, resistance to settling of property is poor, easy reunion, causes that coating failure is too fast, surface irregularity, and coating is limited to a certain extent
Using.The aqueous inorganic zinc-rich anti-corrosion bottom of Multifunction of the problems such as therefore research can overcome zinc powder free settling, bad dispersibility
Paint formula is the problem of urgent need to resolve at this stage.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided at a kind of steel structure surface of corrosion-resistant antirust
Reason aqueous silicic acid potassium zinc rich primer and preparation method thereof.
