Abstract

The invention provides a composite packaging adhesive film and a preparation method and application thereof. The composite packaging adhesive film comprises a core layer and a first skin layer, and the core layer comprises an ionic polymer. The composite packaging adhesive film comprises the core layer and the first skin layer, the core layer comprises an ionic polymer, anions contained in the ionic polymer can be used as a sodium ion trapping agent to block migration of sodium ions, and therefore, the anti-PID effect of the composite packaging adhesive film is improved.

Description

technical field [0001] The invention relates to the technical field of packaging adhesive films for solar photovoltaic modules, in particular to a composite packaging adhesive film and its preparation method and application. Background technique [0002] With the improvement of people's awareness of environmental protection and the emphasis on renewable energy, solar power has developed rapidly as an environmentally friendly energy. [0003] The existing packaging film for solar photovoltaic modules is mainly ethylene-vinyl acetate copolymer (EVA) film, which is mainly because EVA is a polar resin and has good compatibility with polar additives. It is not easy to produce air bubbles, unfused and merging problems. However, during the power generation process of the solar photovoltaic module, a negative voltage will be generated through the outer frame, which will cause the sodium ions and potassium ions in the glass to pass through the adhesive film layer to reach the surfac...
