Abstract
The invention relates to high weather-resistant fluorocarbon paint and a preparation method thereof. The high weather-resistant fluorocarbon paint is prepared from fluorinated monomers, silicon powder, fluorinated compounds, pigment, preservative, an antifreeze agent, emulsifier, a thickening agent, auxiliaries, surfactant and water. The preparation method of the high weather-resistant fluorocarbon paint comprises the steps that the fluorinated monomers, the silicon powder and the fluorinated compounds are polymerized under the action of the emulsifier, the pigment, the preservative, the antifreeze agent, the emulsifier, the thickening agent, the auxiliaries, the surfactant and the water are added for mixing, and the high weather-resistant fluorocarbon paint is obtained. The high weather-resistant fluorocarbon paint is resistant to acid and alkali and capable of adapting to painting in various harsh atmospheric environments and painting of various base planes, and wide application is achieved.
Description
Technical field
The present invention relates to fluorocarbon coating field, particularly a kind of high-weatherability fluorine carbon paint and preparation method thereof.
Background technology
Buildingsurface coating performance of greatest concern is exactly that its weatherability and stain resistance, especially bridge etc. are large-scale publicThe outer wall coating of Architectural Equipment, must have higher durability, and the longer the better the cycle of application and maintenance again, meanwhile, a lotAs the building of city terrestrial reference, the decorative effect of its application is subject to special concern especially, and hope can keep finish paint for a long timeGloss and color, and can keep for a long time beautiful outward appearance.
The most significant feature of fluorine carbon paint is exactly its outstanding weatherability, due to the high bond energy of C-F key, makes the steady of C-F keyQualitative very high, Chinese invention patent CN201110180483 discloses a kind of aqueous high weather resistance environmental protection fluorine carbon paint, adopts water-based fluorineCarbon resin, by the cross-linking reaction of self, generates the high molecular polymer of a kind of high-performance, high-weatherability, changes aqueous high weather resistanceEnvironmental protection fluorine carbon paint, although solve the problem of auto polymerization under normal temperature,, for the fluorine carbon paint under complicated harsh climate environmentDurability of coating problem, does not solve.
Summary of the invention
The object of the present invention is to provide a kind of novel fluoro-carbon paint and preparation method thereof, particularly provide a kind of in various evilsUnder bad environment, all there is fluorine carbon paint of high-weatherability and preparation method thereof.
The main component of high-weatherability fluorine carbon paint of the present invention is:
Described silica flour is 40 microns of following silica flours
Described fluorochemical is hydrofluoride or little molecular fluorine compound;
Described hydrofluoride can be a kind of in alkali metal fluoride, mercuric fluoride, silver fluoride, antimony fluoride, cobaltous fluoride orSeveral; Described little molecular fluorine compound can be one or more in sulfur tetrafluoride, boron trifluoride, tetrafluorosilane.
Described fluorochemical monomer is fluorinated acrylate polymer, is preferably acrylic acid five fluorine ethyl esters, methacrylic acid five fluorineEthyl ester, trifluoromethyl acrylate ethyl ester, trifluoroethyl methacrylate, acrylic acid trifluoro ethyl ester, trifluoromethyl acrylate methyl estersIn one or more.
Described antifreeze is ethylene glycol or glycerine.
Described auxiliary agent is one or more in superfine heavy calcium carbonate, barium sulfate, talcum powder.
The preparation method of high-weatherability fluorine carbon paint of the present invention is:
A. in without water receptacle by after fluorochemical monomer and silica flour mixing and stirring, in system, add fluorochemical,Under 200～400r/min rotating speed, stir;
B. in the mixture obtaining in a, add emulsifying agent, under 600～800r/min rotating speed, control temperature control40～90 DEG C of temperature, stir 10～16h, obtain fluoropolymer polymer seed resin;
