Description
技术领域technical field
本发明涉及光伏封装技术领域，尤其涉及一种光伏组件封装用涂层组合物、封装用复合材料的制备方法及光伏组件。The invention relates to the technical field of photovoltaic encapsulation, in particular to a coating composition for encapsulation of photovoltaic modules, a preparation method of a composite material for encapsulation, and a photovoltaic module.
背景技术Background technique
随着社会的进步，能源需求的扩大，低碳生活越来越引领生活，碳中和对能源和环境的发展提出了更高的要求，对于光伏组件的轻质、柔软等需求越来越被广大客户所青睐。目前市面上主要以工程塑料如PC、PMMA或透明PET等热塑料为方向，也推出在PET表面做氟碳树脂透明背板做为前板使用，但热塑性高分子材料都存在线性膨胀率的原因，不能完美地保护到以硅基为主的电池，特别是在冷热交替的环境中使用。另外，其产品的使用年限以及阻燃性都限制了其使用。现有技术中，有的以透明高分子材料作为前档材料，如中来股份的透明PET。有的以上海上迈做的粉末涂料加玻纤布为载体的封装材料。透明高分子材料作为前档材料存在不阻燃、使用年限短、抗冲击性能不佳，若增加热塑性高分子层厚度，在冷热交替的环境中使用会造成硅基电池片的焊带断裂，造成不可估计的隐患。粉末涂料加工过程中极易造成大量的粉灰，生产环境要求严苛；另外粉末涂料对施工工艺要求较高，极易产生气泡，固化温度较高，能耗大。With the progress of society and the expansion of energy demand, low-carbon life is more and more leading life. Carbon neutrality puts forward higher requirements for the development of energy and the environment. The demand for light weight and softness of photovoltaic modules is becoming more and more popular. Favored by the majority of customers. At present, the market mainly focuses on engineering plastics such as PC, PMMA or transparent PET and other thermoplastics, and also introduces the use of fluorocarbon resin transparent backsheets on the PET surface as front sheets, but thermoplastic polymer materials have linear expansion rates. , can not perfectly protect silicon-based batteries, especially in the environment of alternating cold and heat. In addition, the service life of its products and its flame retardancy limit its use. In the prior art, some use transparent polymer materials as the front material, such as the transparent PET of Jolywood. Some are packaging materials based on powder coatings made by Shangmai and glass fiber cloth. As a front-end material, transparent polymer materials are non-flame retardant, have a short service life, and have poor impact resistance. If the thickness of the thermoplastic polymer layer is increased, it will cause the ribbon of the silicon-based cell to break when used in an environment of alternating cold and heat. cause immeasurable hazards. During the processing of powder coatings, it is easy to generate a large amount of powder ash, and the production environment is strict; in addition, powder coatings have high requirements on construction technology, are prone to bubbles, high curing temperature, and high energy consumption.
