Application No. 2012102564391, the Chinese patent application of entitled " a kind of solar cell backboard and preparation method " discloses a kind of solar cell backboard, it is characterized in that solar cell backboard is symmetrical structure, centre is polyethylene terephthalate layer 40, centre be outwards followed successively by adhesive layer 30, silicon oxide layer 20 and fluoroplastic layer 10.The described solar cell backboard of this invention has gas permeation rate and the low feature of water transmitance, has alkali resistance, weather resisteant, feature that mechanical strength is high simultaneously.This invention is fluorine-containing, easily causes environmental pollution, and relatively costly.
Application No. 2013106903110, the Chinese patent application of entitled " a kind of solar cell backboard and manufacture method thereof " discloses a kind of solar cell backboard and manufacture method thereof, including middle substrate layer, the upper and lower faces of described substrate layer is equipped with fluoropolymer membrane;Connected by adhesive layer between described fluoropolymer membrane and substrate layer;Wherein, described substrate layer is made up of the component of following parts by weight: polyethylene terephthalate 80-90 part, uvioresistant additive 5-15 part;Described fluoropolymer membrane is made up of the component of following parts by weight: Kynoar 70-80 part, polymethyl methacrylate 5-10 part, titanium dioxide 5-10 part, bismuth oxide 1-2 part.Solar cell backboard prepared by this inventive method is simple and reasonable, and barrier property is excellent.The uvioresistant additive of this invention is only capable of uvioresistant, and the resistance for extraneous hygrothermal environment is relatively low.
EVA product of rubber and plastic is novel environment friendly plastics packaging material, has the advantages such as good buffering, antidetonation, ecsomatics corrosion heat insulation, moistureproof, anti-, have nontoxic, do not absorb water.EVA product of rubber and plastic can shape through design, and its shockproof properties is better than the conventional packaging material such as polystyrene (foam), and meets environmental requirement, is the optimum selection of exported product.Can cut relative to Shockproof packaging, molding;Because density variation is bigger, it is also possible to there is purposes the most widely.The feature of EVA: resistance to water: closedcells structure, do not absorb water, moistureproof, water resistance is good.Corrosion resistance: the chemicals corrosion such as sea water resistance, oils and fats, acid, alkali, antibacterial, nontoxic, tasteless, pollution-free.Processability: non junction, and be prone to carry out hot pressing, cut out, gluing, the processing such as laminating.Against shock: resilience and tension stress are high, and toughness is high, has good shockproof cushioning performance.Heat insulating ability: heat insulation, heat-insulating and cold and low temperature performance excellent, can be cold-resistant and tan by the sun.Sound-proofing: closedcells, soundproof effect is good.
The feature of EVA resin is to have good flexibility, the elasticity as rubber, still is able to have preferable pliability at-50 DEG C, and the transparency and lustrous surface property are good, and chemical stability is good, and aging resistance and resistance to ozone intensity are good, avirulence.Good with the miscibility of filler, coloring and molding processibility are good.EVA resin is had many uses.Generally, vinyl acetate content EVA below 5%, its major product is thin film, electric wire, LDPE modifying agent, adhesive etc.;Vinyl acetate content is elastic film etc. at the EVA product of 5%-10%;Vinyl acetate content, at the EVA of 20%-28%, is mainly used in hotmelt and coated article;Vinyl acetate content is at 5%-
45%, major product is thin film (including agricultural film) and sheet material, injection, moulding article, foaming product, hotmelt etc..
Therefore EVA resin is widely used owing to there being the character of uniqueness.In recent years, in area of solar cell, EVA material is widely used, but owing to the EVA mechanical strength of one-component is inadequate, ageing-resistant performance and electric property can not meet the application requirement of field of solar thermal power generation simultaneously, therefore it is accomplished by carrying out composite modified to it, develops a kind of solar cell backboard composite with good mechanical properties, ageing-resistant performance and electric property, meet the needs in solar cell device field.
