Abstract
The utility model relates to a flexible transparent high-obstruction packaging film. According to the utility model, the fatal defect that the obstruction layer of the existing similar product generates cracks in the production and application so as to cause the sudden drop of the obstruction property is solved. The flexible transparent high-obstruction packaging film comprises an obstruction film I, an obstruction film II, an adhesive layer and an uvioresistant layer, wherein the obstruction films I and II are prepared into the packaging film through the adhesive layer with a composite process; a nano material with water absorption and oxygen absorption properties is added in the adhesive layer; and the uvioresistant layer can be directly coated or sputtered on a composite film. The flexible transparent high-obstruction packaging film has the advantages that: 1, the packaging film has multiple obstruction properties and is good in water vapor and oxygen obstruction properties; 2, the nano material added in the adhesive layer can greatly improve the obstruction property of the packaging film; 3, the production technology of a raw material is mature, and cost is low; and 4, the packaging film is easy to process and produce, and production cost is low.
Description
Technical field
The utility model relates to the encapsulating film field, relates in particular to a kind of flexible and transparent high-barrier encapsulating film, is applicable to the encapsulation of solar product etc.
Background technology
Solar energy is with a very important position the regenerative resource industry, is a kind of inexhaustible, nexhaustible green energy resource.Utilizing solar components that solar energy converting is become electric energy is a kind ofly effectively to utilize approach, thereby the shared market share of solar components also increases continuing.Yet, usually poor to the encapsulating film that the core in the solar components shields because of barrier property, cause water, oxygen, corrosivity gas-liquid (like acid rain) destruction to its generation, sharply shortened the life-span of assembly.Commonly used at present improving one's methods is laminated coating or sputter on base film; To improve the barrier property of encapsulating film; Yet can not overcome that barrier layer slight crack occurs in producing and using and critical defect that the barrier property that causes sharply descends; Also improve the cost of encapsulating film, and then also increased the cost of photovoltaic product, be unfavorable for popularizing of product.
Summary of the invention
The utility model is to overcome above-mentioned deficiency, provides that a kind of processing and manufacturing is simple, barrier property is better, lower-cost flexible and transparent high-barrier encapsulating film.
The flexible and transparent high-barrier encapsulating film that the utility model proposes; Comprise Obstruct membrane, adhesive layer, uvioresistant layer; Described Obstruct membrane I adopts combination process to process composite membrane through adhesive layer and Obstruct membrane II, and described uvioresistant layer directly applies or is splashed on the composite membrane.
Described Obstruct membrane is that market scale is big, mature production technology, transparent membrane that cost is low.
Base film and thickness thereof that described Obstruct membrane I and Obstruct membrane II select for use can be identical, also can be different.
Can add a last described nano material with suction, oxygen uptake function in the described adhesive, and not influence properties of transparency after the suction, oxygen uptake, described nano material is metal or metal oxide or nonmetal oxide, like Ag, SiO
2, TiO
2, ATO.
Described Obstruct membrane can carry out conventional barrier inorganic coating, and described inorganic coating is metal oxide or nonmetal oxide or nitride with material, like Al
2O
3, SiO
2, Si

The outermost layer of described flexible and transparent high-barrier encapsulating film can apply one deck soiling protective layer or anti-scratch rigidity layer, and described stain-proofing layer contains fluoride.
A kind of flexible and transparent high-barrier encapsulating film that the utility model provides compared with prior art has following advantage: 1. quite maturation, ample supply of commodities on the market, cost are lower for the production technology of raw material barrier film; 2. encapsulating film has a multiple barrier property, can overcome that existing like product barrier layer slight crack occurs in producing and using and critical defect that the barrier property that causes sharply descends, thereby it is good to intercept the performance of steam, oxygen; 3. be main with combination process, to apply, to be sputtered to main technology and to compare, the line speed of the utility model is fast, production capacity is higher, cost is lower, and environment is not had any harm with at present generally.In addition, product of the present invention not only is applied to the photovoltaic product, also is applicable to the industry that other are had relatively high expectations to barrier property simultaneously.
Therefore; The utility model is a kind of through improving the effective ways of existing barrier encapsulating film technology content increase economic benefit; Has unique multiple obstruct effect; And cost is low, applied widely, the potential market prospect is good, can open up the more applications field, and produces very high economic benefit.
