Abstract

The invention relates to the field of photovoltaic encapsulation materials, in particular to an anti-PID functional masterbatch for a photovoltaic encapsulation film containing Il / Mongolian clay and a preparation method thereof. The master batch is composed of the following components in terms of weight percentage: 50-88% of EVA resin, 4-20% of modified zirconium phosphate crystal, 0.5-10% of crosslinking agent, 0.5-2.5% of silane coupling agent and nano Yimeng clay 5~15%, the balance is additives. The invention overcomes the defect that the masterbatch for photovoltaic packaging film in the prior art does not have anti-PID function, resulting in low battery performance, and the anti-PID function masterbatch for photovoltaic packaging film containing illite / mongolin clay prepared by the present invention has good anti-PID function. It has anti-PID function; at the same time, it can achieve the highest level of flame retardant effect without adding additional flame retardants; in addition, it has good antibacterial and antifungal effects, and can reduce toxic and harmful substances in functional masterbatches.

Description

technical field [0001] The invention relates to the field of photovoltaic encapsulation materials, in particular to an anti-PID functional masterbatch for a photovoltaic encapsulation film containing Il / Mongolian clay and a preparation method thereof. Background technique [0002] In recent years, photovoltaic power generation has gradually become one of the important methods to achieve sustainable development of energy and environment. In solar cells, the encapsulation material is a very important part. Its function is to protect the cells from damage by oxygen and water vapor, maintain or improve the solar energy point-to-photoelectric conversion efficiency, and prolong the service life. Common solar cell packaging films mainly include EVA (ethylene-vinyl acetate copolymer), POE (ethylene-octene copolymer), PVB (polyvinyl butyral), PU (polyurethane) and silicone films. At present, EVA and POE are the mainstream products. [0003] Foreign developed countries started relat...
