Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of sealant for acrylic ester modified solar photovoltaic module, and relate to the preparation method of sealing glue.
Background technology
Solar photovoltaic assembly is also claimed solar module; Sealer existing report in the Chinese patent document as solar photovoltaic assembly; The branch that two components and single-component are wherein arranged; The disclosed condensed type double-component sealer of the sealer of two components such as application for a patent for invention publication number CN1528821A, single-component silicone sealant of a kind of solar module that the sealer of single-component such as application for a patent for invention publication number CN101353563A introduce and preparation method thereof.
The shortcoming (7-9 on the background technology hurdle of the specification sheets page 1 of CN101353563A is capable) of last patented claim has been pointed out in aforesaid back one patented claim; And to U.S. Pat 5238988 disclosed quick-setting room temperature vulcanized silicone rubbers when using, flavescence whether can occur and propose query.Therefore; CN101353563A adopts petroleum resin and filler to come the steam-preventing through performance of lift-off seal glue; But because petroleum resin are the multipolymer of ethylenic unsaturation hydro carbons, lipid and arene mostly, its relative molecular weight reaches 200-3000; The reaction and solidification process in the performance very active, volatile with separate out.And petroleum resin have certain fragility, and petroleum resin are insoluble to lower alcohol and ketones solvent, thereby to preventing seeing through effect and can't showing gratifying degree of water vapor.The not mentioned result who some technical indicator of silicone sealant is tested according to relevant provision in the CNS GB/T9395 table 1 why in the specification sheets of this patented claim; Perhaps be due to this reason; That is, owing to used petroleum resin, steam-preventing transmitance (g/m
2D) be difficult to control to≤1.
In recent years; The solar photovoltaic assembly development is swift and violent; The reason known like industry, solar photovoltaic assembly is installed on outdoor, except require to have good UV resistant irradiation performance, the excellent high and low temperature resistance and corrosion resistance nature; Also require to have good sealing property, promptly quite harsh to the through performance of water-repellancy and water vapor.Again because the life cycle of solar module reaches 20-30 doubly usually, so the sealing effectiveness of sealer must satisfy this time requirement, even is higher than (being longer than) this time span.
The surface of the silicon single crystal of solar photovoltaic assembly or polycrystal silicon cell plate all is pasted with the thin film of silicon single crystal or polysilicon being implemented protection by matrix material being used for of processing; Therefore in a single day water vapor penetrates into sealer inside; Just can influence aforesaid film; And then the mildew phenomena in initiation silicon single crystal or the polysilicon interlayer, and then, because film itself is by used sealer corrosion or because sealer monomer occurs and do not separate out in solidification process; Thereby make film xanthochromia (yellowing) phenomenon occur; To solar cell wafer is that the work-ing life and the photoelectric transformation efficiency of aforesaid silicon single crystal or polysilicon exerts an influence, more particularly, the work-ing life that can shorten silicon chip with reduce photoelectric transformation efficiency.
At present, industry is all explored at the sealer of being devoted to solar photovoltaic assembly is used, and makes every effort to make the transmitance (g/m of water vapor
2D)≤1; And the phase is got sealer in solidification process and monomer all can not occur after solidifying and separate out phenomenon; Satisfy this two conditions because have only, yellowing appears in the film that just can avoid being attached on the silicon chip, and then ensures the work-ing life and the photoelectric transformation efficiency of silicon chip.Yet, in disclosed document, be not seen in the teachings that is able to use for reference, and do not hear the report that business success is arranged yet.For this reason, the applicant has passed through long exploration, has found the scheme of dealing with problems, and will under this background, produce by disclosed technology contents below.
