Abstract

The invention discloses a multi-layer packaging material used for a solar module. The multi-layer packaging material is composed of a POE surface layer A, an EVA core layer B and a POE surface layer C in sequence. The POE surface layer A is an adhesive film, and is made of ethylene and POE colloidal particles, and the surface of the POE surface layer A makes contact with a solar battery piece. The EVA core layer B is made of EVA polymers and performance additives. The POE surface layer C is an adhesive film, and is made of ethylene and POE colloidal particles, and the surface of the POE surface layer A makes contact with a back board in the solar module. The ageing-resistant performance of the material is high.

Description

technical field [0001] The invention relates to a multilayer encapsulation material for solar modules, its preparation process and equipment. Background technique [0002] With the development of my country's photovoltaic industry, the requirements for the performance of packaging materials in solar cell modules are getting higher and higher. Using a single ethylene-vinyl acetate (EVA) polymer as the base material of the encapsulation material can no longer meet the needs in terms of UV and heat and humidity aging resistance. The multi-layer encapsulation film material made of rubber particles of different materials retains the good performance of the single-layer encapsulation film, and makes up for the defects of each single-variety film, forming a new composite encapsulation material. Therefore, it has better physical and mechanical properties than a single encapsulation film. The reasonable combination of different materials can save high-quality raw materials and redu...
