Abstract
The invention discloses a silicon-fluorine-acrylic acid paint. The paint is mainly prepared from a silicon-fluorine-acrylic acid copolymer resin, wherein the silicon-fluorine-acrylic acid copolymer resin is prepared by subjecting organic silicon, organic fluorine, and an acrylic acid copolymer to a core-shell reaction and a coordination reaction, and then subjecting the reaction product to a copolymerization reaction; and after the copolymerization reaction, the advantages of the organic silicon, organic fluorine, and acrylic acid copolymer are integrated into the obtained silicon-fluorine-acrylic acid paint; so the silicon-fluorine-acrylic acid paint has the advantages of excellent weatherability, durability, hydrophobicity and contamination resistant property, can resist the contamination and clean itself, and maintains a beautiful appearance for a long term.
Description
Technical field
What the present invention relates to is a kind of coating, especially a kind of silicon-fluorin acrylic acid coating.
Background technology
Acrylic resin is usually used as the main raw material of coating because having good transparency, good toughness, chemical resistant properties and Gloss Retention, but also there is certain deficiency in it simultaneously, this is because it is a kind of high solvent material, constructional difficulties, and weathering resistance is also not enough.Therefore, at present the main deficiency of conventional exterior coating is exactly that weathering resistance and anti-stain characteristic are not strong, is easier to be polluted and affects the attractive in appearance of buildings, simultaneously due to weathering resistance deficiency, and be unable to undergo the test of time, in very short time, will be again coated with, repeat construction, increase cost.Organic fluorine is used in to the anti-pollution characteristic that can improve coating in coating, but it is generally insoluble in conventional solvent, therefore, it can not use as coating raw material separately.And organosilicon has good adhesivity, resistance to soiling and wear resistance.If above-mentioned three class material copolymerizations are prepared to coating together, the advantage that converges three aspects: will be a kind of desirable exterior coating, can greatly improve resistance to crocking and the weathering resistance of coating, but, yet there are no the report of this respect, therefore External Wall coating is furtherd investigate, and is highly significant.
Summary of the invention
This bright object is prepared a kind of silicon-fluorin acrylic acid coating exactly, to overcome existing coating resistance to soiling and the not strong defect of weathering resistance.
For achieving the above object, the present invention has taked such measure, and a kind of silicon-fluorin acrylic acid coating is to be prepared from according to a conventional method by the raw material of following weight per-cent (%):
Silicon-fluorin acrylic acid resin 45-50 titanium dioxide 18-22 talcum powder 8-14
The female powder 4-6 of wollastonite powder 8-12 silica powder 4-6
Auxiliary agent 1.5-4 surplus is water
Described silicon-fluorin acrylic acid resin refers to the resin being prepared from according to a conventional method by the raw material of following weight per-cent (%):
Vinylidene fluoride 10-20 tetrafluoroethylene 8-12 hexafluoroethylene 10-20
Vinyltriethoxysilane 10-20 vinyltrimethoxy silane 10-20
Vinylformic acid 10-20 ethyl propenoate 3-8 butyl acrylate 3-8
Methyl methacrylate 3-8 vinyl cyanide 1-4 auxiliary agent 1-3.
Described auxiliary agent refers to tensio-active agent conventional in coating industry, emulsifying agent, initiator, defoamer, membrane-forming agent, biocide mildewcide, sanitas and dispersion agent, above-mentioned auxiliary agent all has merchandise sales, and the adding proportion of above-mentioned auxiliary agent is coating industry conventional adding proportion sanctified by usage.
Take the present invention of above-mentioned measure, be prepared from taking silicon-fluorin acrylic acid ternary polymerization resin as main raw material, silicon-fluorin acrylic acid resin is formed by the copolymerization after nucleocapsid reaction and coordination reaction of organosilicon, organic fluorine and acrylic copolymer, after copolymerization, have three's advantage concurrently in one, in order to prepare the present invention, make the present invention have excellent weathering resistance, weather resistance, hydrophobicity and pollution resistance, energy dirt-resistant self-cleaning, keeps attractive in appearance for a long time.The present invention is by the method inspection of standard GB/T/T9755-2001, water tolerance reaches 290 hours and does not non-foamingly come off, it is unchanged that alkali resistance reaches 15 days paint films, brushing resistance reaches and is greater than 12500 paint films without breakage, artificial weathering ageing resistance reaches not efflorescence in 5500 hours, does not come off, colourless splitting, polluting proofing property reaches not to be penetrated coefficient rate of descent and is not more than 5%, and 25 circulations of coating temperature-change resistance are non-foaming, do not come off, flawless, salt fog resistance reach 2500 hours non-foaming, do not come off.
