Description
Technical field
The present invention relates to the sealant material technical field, relate in particular to a kind of solar photovoltaic assembly single-component silicone sealant and preparation method thereof.
Background technology
The energy is the primary condition that the mankind depend on for existence and development; human use's fossil energy has been created unprecedented economic prosperity; but meanwhile, also brought the consequence of energy shortage and environmental degradation, energy dilemma and environmental pollution have become human social and have been badly in need of one of difficult problem that solves.At present, along with the growing tension of global energy situation, solar photovoltaic generating has obtained development rapidly in recent years, and has obtained large-area promotion and application as a kind of clean energy alternative of regeneration.
Significant components-the solar cell of solar photovoltaic generating is by the monolithic solar cell with high conversion efficiency, EVA glued membrane, low iron toughened glass and the Tedlar(TPT that is composited by fluoroplastics, terylene) notacoria forms.These elements heated lamination under vacuum becomes as a whole, finally by anticorrosion aluminum alloy frame and power supply boxcar (being terminal box) are installed, becomes solar cell assembly finished product.Cause oxidized in the solar cell assembly and turnover ratio reduction that cause in order to prevent that airborne water and oxygen from entering, must be at aluminum frame around the solar cell plate, be the gap of cell panel sunny slope sheet glass reverse side TPT plate and aluminium frame, adopt being bonded and sealed property and the good seal gum of weather-resistant performance to seal; Also must adopt the seal gum fixing seal that bonds around the power supply boxcar housing, with the protection circuit plate, increase the service life.
Because the solar cell assembly is mainly used in outdoor rugged environment relatively, need bear the baptism of exposing to the sun and rain for a long time, the seal gum that therefore requires to adopt has good ultraviolet-resistant aging performance and high-low temperature resistant weathering age performance.Seal gum can be followed the phenomenon of color jaundice, i.e. xanthochromia in aging process takes place.Xanthochromia not only influences the outward appearance of product, limits its Application Areas, and key is it also is the signal of interest that its structure and performance change, and causes the adhering and sealing degradation, and the easy seepage of aqueous vapor enters photovoltaic module, and then influences the work-ing life of solar photovoltaic assembly.Than conventional seals glue, the solar photovoltaic assembly need possess higher requirement with seal gum.
Room temperature sealing silicone sulfide glue has remarkable ultraviolet resistance and high-low temperature resistant weathering age performance, compare its weather resistance under mal-condition with the seal gum of other type outstanding especially, especially single-component room temperature vulcanized silicone sealant, because the siloxane bond of its main component is more stable, so ageing-resistant performance excellence, and easy to use, thereby be widely used, be best suited for being applied to the seal gum kind of solar cell assembly.But at present, in application process, still exist following technological deficiency:
(1) the deep layer curing speed is slow, cured thickness is little
Single-component room temperature vulcanized silicone sealant need rely on moisture to carry out crosslinking curing, and moisture is diffused into relatively difficulty of glue-line inside, and deep layer is solidified slower, and the thickness of curing has only 2～3mm usually, is difficult to realize the serialization streamline operration; And making the solar panel after the assembling in general need could carry after seven, eight hours, seal gum solidifies fully and will bring serious negative impact for the production efficiency of solar photovoltaic producer with several days time.
(2) anti-yellowing property remains to be improved
Most of products all adopt the organic titanium complex compound as catalyzer in the prior art, because organic titanium itself is pale yellow or light red, catalyzer is not participated in chemical reaction in the sealing glue solidifying process, the catalyzer that has trace after the curing oozes out, and causes the EVA flavescence in the photovoltaic module easily.In addition, the relatively poor and remaining impurities of some complementary material (as color stuffing and auxiliary agent etc.) ageing resistance also can influence anti-yellowing property, and has limited the application of a lot of excellent performance raw materials.
(3) flame retardant resistance is relatively poor
Prior art solar photovoltaic assembly does not all have flame retardant properties with silicone sealant, and work-ing life and the security of solar photovoltaic assembly brought very big influence.
(4) bad adaptability, not good to the cementability of base material
The need adhesives kind that the solar photovoltaic assembly relates in assembling process is more, as aluminium, PVC, PMMA, ABS, TPT etc., therefore requires seal gum to have cementability widely.But prior art products is not good to bad adaptability, the cementability of solar photovoltaic assembly base material commonly used, can not satisfy the practical application request of solar photovoltaic assembly industry well.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, but the solar photovoltaic assembly seal gum of a kind of fast setting, excellent performance is provided, to satisfy particular requirement and the practical application request of solar photovoltaic assembly industry.Another object of the present invention is to provide the preparation method of above-mentioned solar photovoltaic assembly with seal gum.
Purpose of the present invention is achieved by the following technical programs:
