Abstract
The invention relates to a fluorine-containing heavy-duty anticorrosive coating and its application. The coating comprises an epoxy vinyl resin, hexafluorobutyl methacrylate, methacrylate, a diluent and an initiator, wherein the mass ratio of the epoxy vinyl resin to the hexafluorobutyl methacrylate to the methacrylate is 4:0.5-6:0-0.4; the mass of styrene accounts for 20-65% of the mass of the epoxy vinyl resin; and the amount of he initiator accounts for 0.1-1% of the total mass of the coating. The fluorine-containing heavy-duty anticorrosive coating of the invention combines the excellent adhesion of epoxy resin coats and good chemical anticorrosive characteristics of fluorocarbon coats, coat products of the coating have already have the chemical anticorrosive capability under extreme environments through continuous technical innovation and improvement, and simultaneously the coating products have excellent weatherability same as that of the fluorocarbon coats, excellent adhesion same as that the epoxy resin coats, and a use temperature which is near 100DEG C higher than that of the epoxy resin coats and the fluorocarbon coats averagely.
Description
Technical field
The present invention relates to a kind of heavy-duty coating and application thereof, particularly a kind of fluorine-containing heavy-duty coating and application thereof.
Background technology
Along with steady development of economy, all trades and professions to the demand of corrosion resistant coating also in quick growth.At present; The world market has chemical corrosion resistant coating prod to sell; But possibly consider that this type of coating prod seldom exports market, inland of China from certain stake, the coating prod of outlet home market is used for some JV for joint venture's processing related prods basically; As be used for the corrosion resistant coating etc. of chemical experiment platen surface, be difficult to find the coating magma that can be used for product surface processing.
At present, home market what is called " heavy-duty coating " on sale also only is applicable to generally speaking Chemical Preservation and weather-proof, and the difficult chemical corrosion resistant needs that adapt under the abominable chemical environment more can't satisfy the chemical corrosion resistant needs under the extreme chemical environment.At present on heavy anticorrosion market, have significant product and mainly contain two types; One type is to be the coating prod of basic raw material with epoxy resin; This product possesses medium Chemical Preservation ability, good weathering resistance, good sticking power and good thermostability, can be used as anticorrosion under the general chemical environment.Another kind of product is to be the coating prod of basic raw material with perfluor or polyfluoro macromolecular material; Market is called " fluorocarbon coating "; This coating prod is than the epoxy resin series products; Weathering resistance with better chemical rotproofness, excellence, and the thermostability close with epoxy resin can be used for the corrosion resistant under the abominable chemical environment.But there is cured in place technology relative complex in this type of coating prod, more weak these two critical defects of the sticking power of coating and substrate surface, the difficult post coat requirement of satisfying large-sized object.Fluorocarbon coating on sale, that can be used for large-sized object post coats such as external wall on the market, the content of its fluorine is relatively low, and the coating after the curing only can satisfy weather-proof under the general condition, can't satisfy the corrosion resistant under the abominable chemical environment.In sum, at home on the market, do not have the high corrosion resistant coating prod that is fit under the abominable or extreme chemical environment basically at present, still, domestic all trades and professions are but still very huge to this type of special coating product demand.
Summary of the invention
One of the object of the invention is to provide a kind of fluorine-containing heavy-duty coating.
Two of the object of the invention is to provide the method for use of this protective system
For achieving the above object, the present invention adopts following technical scheme:
A kind of fluorine-containing heavy-duty coating is characterized in that this system component is: epoxy vinyl resin, methylacrylic acid hexafluoro butyl ester, methacrylic ester, thinner and initiator; Wherein the mass ratio of epoxy vinyl resin, methylacrylic acid hexafluoro butyl ester and methacrylic ester is: 4:0.5～6:0～0.4; Described cinnamic quality is the 20-65% of epoxy vinyl resin quality; The consumption of described initiator amount is the 0.1-1% of coating total mass.
Above-mentioned methacrylic ester can be TEB 3K, Jia Jibingxisuanyizhi, Propenoic acid, 2-methyl, isobutyl ester or methacrylic tert-butyl acrylate.
Above-mentioned initiator can be Diisopropyl azodicarboxylate, ABVN, azo-bis-iso-dimethyl, Lucidol or methylethyl ketone peroxide.
The general structure of above-mentioned thinner is:
A kind of method of use of above-mentioned fluorine-containing heavy-duty coating is characterized in that the concrete steps of this method are: successively each component mixed, and the formation slurries that stir; These slurries are coated on the base material, form coating,, solidified 1～3 hour then at 90～120 degrees centigrade.
Above-mentioned base material can be glass, timber or steel.
Above-mentioned coating can be brushing, roller coat or air.
The thickness of above-mentioned coating is 30～1000 microns.
Compare with prior art; Fluorine-containing heavy-duty coating of the present invention has had good sticking power and the good chemical corrosion resistant performance characteristics of fluororine-carbon coating of epoxy resin type coating concurrently; Simultaneously, through continuous technological innovation and improvement, this coating prod has possessed the chemical corrosion resistant ability under the extreme environment; Simultaneously; This coating prod possesses and the same excellent weather-proof ability of fluororine-carbon coating, with the same good sticking power of epoxy coating, on average exceeds the nearly 100 degrees centigrade characteristics such as use temperature of epoxy coating and fluororine-carbon coating.
