Description
Technical field
The present invention relates to zinc-rich paint technical field, more particularly to a kind of surface treatment of long acting antibiotic formed steel construction is with aqueous
Potassium silicate zinc rich primer and preparation method thereof.
Background technology
Zinc rich primer is a class anticorrosive paint product of the zinc powder to act 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 at present conventional mainly 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.）For film forming
Base fluid（Binder）, zinc powder for pigment anticorrosive paint.Zinc powder generates cancellated zinc silicate with silicate reaction, while
Also zinc silicate iron complex is defined in metal surface with iron and steel reaction, thus form the stronger chemistry of bond energy in steel surface and inhale
It is attached.And cohesive force of the adhesive force of epoxy zinc rich primer from resin to 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 far superior to has
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 it is prepared for a kind of styrene-acrylic emulsion as modifying agent with styrene-acrylic emulsion to change
The aqueous inorganic zinc-enriched coating of property.
But only have been introduced to styrene-acrylic emulsion addition and to the pliability of coating in document, with production technology and
That what is filled a prescription continues to optimize, discovery flake zinc powder advantage in terms of covering power, floating capacity and screening ability compared with spherical zinc powder
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 a kind of long acting antibiotic formed steel construction surface treatment
With aqueous silicic acid potassium zinc rich primer and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of long acting antibiotic formed steel construction surface treatment aqueous silicic acid potassium zinc rich primer, is prepared by the raw materials in：

The preparation method that aqueous silicic acid potassium zinc rich primer is used in a kind of described long acting antibiotic formed steel construction surface treatment, including
Following steps：
（1）Aqueous epoxy resin emulsion is slowly added dropwise toward styrene-acrylic emulsion, 70-80 DEG C is warming up to, isothermal reaction 20-30 minutes,
50-60 DEG C is cooled to, SWNT ultrasonically treated 25-30 minutes are added, adds ferrocene to continue ultrasonically treated 10-15 point
Clock, obtains modifying cinepazid emulsion；
（2）By deionized water water and absolute ethyl alcohol with the mixing of volume ratio 1: 4, MTMS, ytterbium chloride is added to adjust
Section pH is 4.5 or so, is stirred vigorously at 25-30 DEG C 1 hour, and the constant constant temperature of keeping temperature hydrolyzes 24 hours to obtain modification liquid；
（3）By after scale zinc powder oil removing drying and processing with step（2）Modification liquid mixes, agitation grinding 30 minutes, Jing centrifugations, ethanol
Wash, filter, drying the scale zinc powder that must be modified；
（4）By feldspar in powder at 810-900 DEG C high-temperature calcination 20-30 minutes, be cooled to room temperature add viscose rayon, shitosan
Grinding 1-2 hours；
