Abstract
The present invention discloses a kind of preparation method of fluororine-carbon coating, this fluororine-carbon coating is made up of first component and component B, during use, be that 1 ~ 2:1 mix with component B according to the ratio of quality consumption by first component, wherein first component is made up of fluorine carbon base polyurethane prepolymer for use as, nanometer inorganic filler, hydrolysis stabilizer, dispersion agent, flow agent, tin class catalyzer, initiator, vinylformic acid hydroxyl ester, anhydrous diluents; Component B is made up of Hydroxylated acrylic resin, isocyanate curing agent and anhydrous diluents.The present invention effectively can improve crosslinked polymer density in fluororine-carbon coating, makes it to have IPN inierpeneirating network structure more closely.Obtained fluororine-carbon coating, weather-proof, water-fast, chemicals-resistant, salt spray resistance excellence, hardness and wear resisting property are given prominence to, and are a kind of fluororine-carbon coatings that can be used for the excellent property of solar cell backboard.
Description
Technical field
The present invention relates to a kind of preparation method of fluororine-carbon coating, belong to material surface resist technology field.
Background technology
Photovoltaic industry, as the important component part of renewable energy source, has become the main method solving global energy crisis.After 2008, the application of solar cell is constantly expanded, from aviation, surface power station to roof, curtain wall, from temperate zone, the torrid zone to high and cold, desert region, become the part in people's life gradually.Riseing of solar cell demand, also determines the generalization of material used for solar batteries, production domesticization.Solar module main raw used, comprises crystal silicon chip, silver slurry, toughened glass, EVA adhesive film, terminal box, backboard.In China's Own Brand, production technique and the quality product of the first five kind material all reach level leading in the world, no longer rely on import.But the quality level of the backboard of domestic production and American-European-Japanese also there is a big difference, also far can not meet the requirement of some harsh and unforgiving environments.
Before 2008, on market, the structure of backboard product mainly contains four kinds, as TPT, TPE, 3A, PET.All based on import, as Isovolta, Madico, Coveme, Honeywell, Krempel, 3M, SFC, Toyal.In the end of the year 2008, in Du Pont under the monopolization of Tedlar fluorine film, holding at high price of backboard, domestic encapsulation company is proposed the higher application type backboard of cost performance.Application type backboard mainly based on domestic independent research, as come in Hangzhou Foster, Suzhou, Suzhou match 5 etc.Application type backboard can not only reach the performance of identical with TPT backboard water-fast, heat-resisting, ultraviolet aging resistance, also has easy production technique, therefore obtains in recent years applying more and more widely.But; by contrast; the anti-blown sand of application type backboard is relatively weak; wear resistance is also less than 30% of TPT type backboard; in the area that some weather is harsh, the Northwest that especially dust storm is large, backboard external coating (EC) drops by dust storm very easily delamination of swiping; thus reduce the provide protection of backboard to assembly, reduce work-ing life and the generating efficiency of solar cell.Therefore, develop a class wear resistance higher, simultaneously water tolerance, alkaline-resisting, solvent resistant, ageing-resistant etc. in all show excellent over-all properties fluororine-carbon coating be the problem that solar cell backboard industry urgently solves.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes deficiency of the prior art, provides a kind of preparation method of fluororine-carbon coating.
For technical solution problem, solution of the present invention is:
A preparation method for fluororine-carbon coating, comprises the following steps:
(1) preparation of first component, comprises following sub-step:
