Abstract

The invention discloses an EVA (Ethylene Vinyl-Acetate) glue film special for packaging a double glass solar assembly and a preparation method thereof. The EVA glue film special for packaging the double glass solar assembly comprises the following components in percentage by weight as follows: 70-90% of ethylene vinyl-acetate copolymer, 5-20% of ethylene-octylene copolymer, 2-10% of polyethylene, 0.1-1.0% of initiator, 0.1-1.5% of antioxygen, 0.1-1.0% of ultraviolet absorbent, 0.05-1.0% of light stabilizer and 0.5-1.5% of tackifier which are grafted and pretreated and then subjected to tape casting. The glue film provided by the invention has excellent an anti-impact modulus moisture separating effect and lower mobility, and is applied to packaging the double glass solar assembly to avoid deficiencies such as bubbles and displacement of the double glass assembly, so that the performance demand of falling ball impact of the double glass assembly is met. In addition, the preparation method provided by the invention is simple in process, efficient in production and low in energy consumption, and the assembly packaged is quick to cool and the product cost is lowered.

Description

technical field

[0001] The invention relates to a special EVA adhesive film for double-glass solar module packaging and a preparation method thereof, which is applied to the preparation of solar cell module packaging adhesive film and the packaging of double-glass solar photovoltaic modules, including thin-film battery double-glass components and crystalline silicon battery double-glass components. Background technique

[0002] Building-integrated photovoltaics (BIPV) uses buildings to generate electricity, so it has strict requirements on building safety. Generally, double-glass solar modules with composite layers composed of two pieces of glass and solar cells are used. Double-glass photovoltaic modules are composed of the following parts: (1) The two pieces of glass must be toughened safety glass, and the side facing the light must be ultra-clear glass; (2) Cells: monocrystalline silicon, polycrystalline silicon, and amorphous silicon are all available ; (3) Composite la...
