Problems solved by technology

However, the packaging film that protects the core part of the solar module is often damaged by water, oxygen, corrosive gas and liquid (such as acid rain) due to its poor barrier performance, which drastically shortens the life of the module and increases It reduces the cost of photovoltaic products, which is not conducive to the rapid popularization of photovoltaic products

Embodiment 1

[0021] see figure 1 , a flexible transparent high-barrier packaging film, including barrier film I (1), adhesive layer (2), barrier film II (3), anti-ultraviolet layer (4) and nanomaterials (5), the glue The adhesive layer (2) is added with nano-materials (5) with functions of absorbing water and oxygen, such as nano-Ag particles, and the barrier film I (1) passes through the adhesive layer (2) and the barrier film II (3 ) is prepared into a composite film by a composite process, and the anti-ultraviolet layer (4) is coated or sputtered on the outside of the barrier film II (3), to obtain a flexible transparent high-barrier packaging film with multiple barrier properties.

[0022] Preferably, the barrier film adopts a plastic film with good transparency.

[0023] As a further preference, the barrier film is a barrier film with sufficient supply and low price.

[0024] As a further preference, the barrier film is half or even thinner than the ordinary packaging film.

Embodiment 2

[0031] see figure 2 , a flexible transparent high-barrier packaging film with an antifouling layer and a protective layer, including a barrier film I (1), an adhesive layer (2), a barrier film II (3), an anti-ultraviolet film (4), nano Material (5), antifouling coating (6), sealing film (7) and protective film (8). Barrier film I (1), adhesive layer (2), and barrier film II (3) were prepared according to the composite process in Example 1, and the anti-ultraviolet film (4) and antifouling coating (6) were sequentially coated to the initial On the prepared composite barrier film, the sealing film (7) and the protective film (8) are sequentially compounded on the other side of the preliminarily prepared composite barrier film to obtain the product of Example 2.

[0032] Preferably, a layer of material (5) with functions of absorbing water and oxygen, such as nano-Ag particles, is sputtered on the conventional barrier film.

[0033] Preferably, a layer of antifouling protectiv...

Abstract

The invention discloses a flexible transparent high-barrier packaging membrane, which includes barrier membranes, an adhesive layer and an anti-ultraviolet layer, wherein the barrier membranes include a barrier membrane I and a barrier membrane II; a nano-material with water absorption and oxygen absorption performances is added into the adhesive layer; the barrier membrane I and the barrier membrane II are compounded through the adhesive layer to prepare a composite membrane; the anti-ultraviolet layer can be directly coated or sputtered on the composite membrane. The packaging membrane has high barrier performance, and also has a simple entire production process, high production line speed, a mature raw material production technology and low cost; and thus, the scale-up production is high, and the product cost is far away lower than that of the similar products on the current market. Most importantly, the product can make up for the critical defect of sharply declined barrier performance caused by cracks produced in production and application of the similar product barrier layers.

Description

technical field [0001] The invention relates to an encapsulation film, in particular to a flexible transparent high-barrier encapsulation film, which is particularly suitable for the encapsulation of solar products and other products requiring high barrier performance. Background technique [0002] Environmental pollution and energy shortage have become problems that cannot be ignored by human beings, prompting governments of various countries to promote the research, development and application of renewable resources. Solar energy plays an important role in the renewable energy industry, and it is an inexhaustible green energy. It is estimated that the solar energy received by the earth every year is equivalent to 3000 times of the energy obtained by human burning fuel every year; as long as human beings make good use of solar energy, they can meet their own energy needs and avoid environmental problems caused by burning fuel. Using solar modules to convert solar energy in...
