Abstract

The invention provides a high-thermal conductivity insulating solar cell-packaging film. Acrylic ester-modified EVA (ethylene-vinyl acetute) superpolymer is adopted as a solar cell-packaging film, and is added with high-thermal conductivity powder and various auxiliaries, and thereby the high-thermal conductivity insulating packaging film for packaging a solar photoelectric-photothermal integrated system is prepared. A preparation method for the packaging film includes the following steps: according to a certain proportion, the materials are uniformly mixed, the mixture is poured into a double-screw extruder to be subjected to mixing, plastifying, extruding and cutting into granules, and the granules are then molded by compression. The high-thermal conductivity solar insulating packaging material prepared by the invention has excellent bonding property, high crosslinking density, high heat-resistant property, excellent insulativity and high aging resistance, and can withstand outdoor ultraviolet light, thermal oxidation and moisture corrosion for a long time, and the yellowing resistance of the high-thermal conductivity insulating packaging material is greatly enhanced in comparison with the yellowing resistance of like products.

Description

technical field [0001] The patent of the present invention relates to the field of insulating materials, in particular to a hot-melt-bonded thermally conductive insulating material for encapsulation of a solar-photoelectric-photothermal-integrated system. Background technique [0002] With the shortage of resources, the deterioration of the environment and the continuous increase of energy costs, many countries have turned their attention to renewable new energy, among which the application of solar energy has received much attention. No matter in terms of the amount of resources, the universality of distribution, or in terms of cleanliness and technical reliability, solar energy is more superior than other renewable energy sources, and it is an inexhaustible and carbon-free energy source. Green energy. There are two main directions for the utilization of solar energy, one is to convert solar energy into thermal energy, and the other is to convert solar energy into electric...
