Abstract

The invention relates to the field of photovoltaic packaging materials and particularly relates to an illite/smectite clay containing anti-PID functional master batch for a photovoltaic packaging filmand a preparation method for the illite/smectite clay containing anti-PID functional master batch. The master batch is prepared from the following ingredients in percentage by weight: 50% to 88% of EVA resin, 4% to 20% of modified zirconium phosphate crystal, 0.5% to 10% of cross-linker, 0.5% to 2.5% of silane coupler, 5% to 15% of nano illite/smectite clay and the balance of auxiliaries. According to the illite/smectite clay containing anti-PID functional master batch for the photovoltaic packaging film and the preparation method for the illite/smectite clay containing anti-PID functional master batch, the defect in the prior art that master batches for photovoltaic packaging films do not have an anti-PID function and thus performance of batteries is low is overcome; the illite/smectiteclay containing anti-PID functional master batch for the photovoltaic packaging film, prepared by the method, has a good anti-PID function; meanwhile, a top-class flame-retardant effect is achieved under the condition of not additionally adding flame retardants; and furthermore, the illite/smectite clay containing anti-PID functional master batch further has the advantages that the antibacterial and mildewproof effect is good, meanwhile, toxic and harmful substances in the functional master batch can be remarkably reduced, and the like.

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...
