Abstract
The invention relates to a coating, especially to an aqueous coating and specifically to an anti-sticking aqueous fluoro-silicone coating. The invention also relates to a preparation method for the coating. The anti-sticking aqueous fluoro-silicone coating is characterized in that the coating is obtained by adding an organosilicon waterproof agent and a polysiloxane isolating agent into an aqueous fluoro-silicone coating. The method for preparing the aqueous fluoro-silicone coating is to sequentially add an auxiliary agent, a pigment and filler, silicone-acylate emulsion, aqueous fluororesin emulsion, the organosilicon waterproof agent and the polysiloxane isolating agent in deionized water with stirring at a low speed and evenly mix all the above-mentioned components. The anti-sticking aqueous fluoro-silicone coating provided in the invention has ultra-strong hydrophobicity and extraordinary non-sticking performance, shows a striking water droplet effect and peeling performance, effectively prevents arbitrary posting of unauthorized advertisements in cities and is capable of effectively restraining harm of commonly referred urban psoriasis to urban environmental landscape.
Description
?
Technical field
The present invention relates to a kind of coating, particularly a kind of water-borne coatings is specifically related to a kind of antiseized type water-based silicon fluoride paint.The invention still further relates to the preparation method of this coating.
Background technology
For a long time, " small advertisement " that put up carelessly in the streets and lanes, city (being commonly called as " city psoriasis ") is difficult to be controlled effectively all the time, become urban health management, city appearance environment department and all circles civic " Enemy of the State "." black small advertisement " behavior is illegally puted up in relevant department's severe strike that once repeatedly adopted measures; And make the removing " small advertisement " that ins all sorts of ways; As manual work root out, water blast gun flushing, but poor effect, and very waste of manpower, material resources, financial resources; The paper scrap and the resistates of cleaning also can cause the pollution once more to urban environmental hygiene, also are difficult to stop the appearance that repeats of " small advertisement " simultaneously.
The existing medium-to-high grade elasticity of water-based, the pure silicon acrylate dope of generally promoting on the market; Though have weather-proof preferably, acid and alkali-resistance and water resistance; But anti-fouling effect is not good; Can't resist the puzzlement that the unrest of " small advertisement " is puted up, month after month be commonly called as the infringement of city " psoriasis " at the part dead angle in streets and lanes throughout the year, bring infinite future trouble for the city renovation.
And the existing part non-stick resin oiliness class dual-component coating that is difficult to popularize in an all-round way on probation in city, its peculiar smell is heavy, and is big to atmospheric pollution; Dilution range is limited to, and under the hot conditions, is prone to condensation cure during construction; Back tack is high, and the construction clout can't hermetically stored, or stores not have and ensure.
Publication number is CN1807526A, and open day is a kind of silicon fluoride super-amphiphobic non-stick coating material of the Chinese invention patent ublic specification of application on July 26th, 2006.This coating is made up of coating part and solidifying agent two portions, and hardener dose accounts for the 6.5-12% of coating part weight, and described coating partly is made up of following raw materials by weight percent: fluorocarbon resin 30-50%; Silicone resin 10-20%, color stuffing 3-30%, silicon powder 1-5%; Fluorine micro mist 3-10%; Auxiliary agent 0.01-3%, organic solvent 5-30%, described solidifying agent are at least a of biuret, HDI tripolymer and organotin; Described fluorocarbon resin is to be formed its fluorine content >=wt35%, solid content >=50% by tetrafluoroethylene monomer, alkyl vinyl ester and function monomer copolymerization; Described silicone resin is the terminal hydroxy group silicone resin.Described alkyl vinyl ester can be vinyl acetate, and described function monomer is rare propyl alcohol and 11 diluted acids.Described fluorine micro mist can be ptfe micropowder, particle diameter≤5um; Described silicon powder can be aerosil, particle diameter≤5um.Described organic solvent can be ester class, ketone or solvent of ether ester type.
Publication number is CN101307210A, and the Chinese invention patent Shen Qing Publication specification sheets that open day is on November 19th, 2008 discloses a kind of super-hydrophobic water-based fluorine silicon-acrylic coatings that contains nanoparticle.This coating is that the component mixed preparing by following massfraction forms: water, 30%-65%; Organosilicon crylic acid latex, 10%-40%; The water-based fluororesin emulsion, 10%-40%; Nanometer oxide particle, 1%-10%; Inorganic drilling compound, 1%-15%; Mineral acid, surplus.
Publication number is CN101368019A, and the Chinese invention patent Shen Qing Publication specification sheets that open day is on February 18th, 2009 discloses a kind of novel watersoluble fluorine paint.The composition of this novel watersoluble fluorine paint comprises: the deionized water weight ratio is 24, the Ucar 35 weight ratio is that 1,1250 order water-ground limestone weight ratio is 9, and skimmer B-199 weight ratio is 2; Dispersion agent S-800 weight ratio is 2, and fluoro-resin emulsion F500-2 or F500-3 weight ratio are 52, and furtherance film alcohol ester 12 weight ratios are 2; The thickening material weight ratio is 5, and skimmer D1620 weight ratio is 1, and deionized water, Ucar 35, water-ground limestone, skimmer, dispersion agent are added common pigments; High speed dispersion, grinding are filtered, and add fluoro-resin emulsion, furtherance film, thickening material, skimmer dispersion; 85 rev/mins, 30 minutes.
Publication number is CN101338163A, and the Chinese invention patent Shen Qing Publication specification sheets that open day is on January 7th, 2009 discloses a kind of elastic emulsion paint.This elastic emulsion paint is to be obtained by the preparation of following weight fractional raw materials mix: deionized water 150 ~ 200, adipic dihydrazide 2 ~ 5, Natvosol 1 ~ 2, Ucar 35 10 ~ 30, dispersion agent 4 ~ 6; Skimmer 1 ~ 2, sanitas 0.5 ~ 2, pH value stabilization agent AMP-95,0.5 ~ 2; 215 white titanium pigments 45 ~ 55, wollastonite powder 80 ~ 150, kaolin 40 ~ 60,800 order coarse whitings 120 ~ 180; Water-based fluorocarbon resin 100 ~ 120, benzene emulsion 50 ~ 100, elastic emulsion 250 ~ 300, film coalescence aid 5 ~ 20; Wetting agent X-405,1 ~ 3, rheology modifier 2 ~ 5, thickening material 5 ~ 10.1), adipic dihydrazide adds in the deionized water preparation method of this elastic emulsion paint may further comprise the steps:, stirring at low speed is dissolved it fully; 2) add Natvosol, Ucar 35, dispersion agent, skimmer, sanitas and pH value stabilization agent AMP-95 successively, stir; 3), under stirring at low speed, add 215 white titanium pigments, wollastonite powder, kaolin and 800 order coarse whitings successively, high speed dispersion 45 ~ 55min reaches≤45um to the slurry fineness; 4), under stirring at low speed, in slurry, add water-based fluorocarbon resin, benzene emulsion and elastic emulsion successively, it is mixed; 5), under the stirring at low speed, add film coalescence aid and wetting agent X-405 successively, to suitable viscosity, obtain product behind stirring at low speed 10 ~ 20min with rheology modifier and thickening material adjustment product.
