Abstract

The invention provides an adhesive film composition containing polystyrene microspheres as well as a preparation method and application of the adhesive film composition. The adhesive film composition is prepared from the following components in parts by weight: 80 to 98 parts of matrix resin, 1 to 20 parts of polystyrene microspheres, 0.2 to 2 parts of main cross-linking agent, 0.2 to 1 part of auxiliary cross-linking agent and 0.05 to 1 part of silane coupling agent, the silane coupling agent comprises a combination of a silane coupling agent monomer and a silane coupling agent oligomer. According to the adhesive film composition, the polystyrene microspheres are added into the matrix resin and are matched with other auxiliaries for use, so that the transmittance of the adhesive film can be improved on the basis of ensuring the mechanical property of the adhesive film, and the adhesive film can present different colors; the photovoltaic module comprising the adhesive film composition is high in power generation power and attractive in appearance.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic modules, and in particular relates to an adhesive film composition containing polystyrene microspheres, a preparation method and application thereof. Background technique [0002] Building-integrated photovoltaics (BIVP) is a technology that integrates solar power (photovoltaic) products into buildings. With the continuous development of new energy and the increasing demand for urban energy conservation, emission reduction, and green environmental protection, building integrated solar photovoltaics has increasingly become a new trend in solar energy application power generation. [0003] For the sake of aesthetics, more and more BIPV components not only choose black, but also have other colors. In the prior art, colors are provided by adding dyes or pigments to the film. CN204375770U discloses a kind of color encapsulating adhesive film, comprises the transparent ethylene-vinyl acetate (EVA)...
