High-weather-resistance ultraviolet-blocking photovoltaic backboard base film and preparation method and application of high-weather-resistance ultraviolet-blocking photovoltaic backboard base film
The invention belongs to the technical field of photovoltaic cell materials, and particularly discloses a high-weather-resistance ultraviolet blocking photovoltaic backboard base film and a preparation method and application thereof. The high-weather-resistance ultraviolet blocking photovoltaic backboard base film is of a multi-layer structure and comprises the surface layer and the core layer, the modified master batch containing the ultraviolet light absorber and the ultraviolet blocking agent is added when the surface layer is prepared, the weather resistance of the base film can be improved (more than 60 H), the base film can have high blocking performance in the ultraviolet band, and the service life of the base film is prolonged. Normal use of the photovoltaic backboard in drought and high ultraviolet radiation weather is ensured, and durability and power generation efficiency of photovoltaic accessories are improved. The composition and the structure of the base film are redesigned, various ultraviolet light absorbers and blocking agents are compounded for use, and meanwhile, a three-layer co-extrusion and two-way stretching preparation process is adopted, so that the base film can be endowed with good weather resistance, radiation resistance and mechanical property, the production cost of the base film is reduced, and the base film has a good application prospect and a relatively high economic value.
本发明属于光伏电池材料技术领域，具体公开了一种高耐候紫外阻隔光伏背板基膜及其制备方法和应用。本发明提供的高耐候紫外阻隔光伏背板基膜为多层结构，包括表层和芯层，表层在制备时添加包含紫外线吸收剂和紫外线阻隔剂的改性母料，不仅能提高基膜的耐候性(超过60H)，还能使基膜在紫外波段具有较高的阻隔性能，确保光伏背板在干旱、高紫外辐射天气下的正常使用，提高光伏附件的耐用度和发电效率。本发明通过重新设计基膜组成和结构，将多种紫外线吸收剂和阻隔剂复配使用，同时采用三层共挤、双向拉伸制备工艺，能赋予基膜良好的耐候性、抗辐射性和机械性能，并降低基膜的生产成本，具有良好的应用前景和较高的经济价值。
