Description
本发明涉及粘合剂技术领域，具体涉及一种光伏板基层粘合用防水粘合剂。The present invention relates to the field of adhesive technology, and in particular to a waterproof adhesive for photovoltaic board base layer bonding.
太阳能背板一般具有三层结构，外层保护层为含氟聚合物层，具有良好的抗环境侵蚀能力，中间层为能够双向拉伸的聚脂薄膜层，具有良好的绝缘性能以及力学性能，内层为含氟聚合物层或是聚乙烯-醋酸乙烯酯共聚物层，与封装材料EVA具有良好的粘结性。目前国内外背板材料的制备方法，大都是在PET阻隔膜的两个表面分别涂抹聚氨酯粘结剂，然后再分别复合氟膜和氟膜、氟膜和EVA膜、氟膜和PE膜，这种制备方法主要解决了氟膜与PET膜、PET膜与EVA(PE)膜的粘结性问题，但仍存在缺陷：采用阶段式的复合手段，即先在PET膜的一表面涂胶并复合一层膜后，再在PET膜的另一表面涂胶并复合另一层膜，工序比较复杂；国内聚氨酯粘结剂都需要进口，使得太阳能背板的生产成本过高；由于聚氨酯粘结剂为溶剂型粘结剂，需要使用大量的有机溶剂，而目前使用的粘合剂粘合效果不好，且防水性能不够。The solar backsheet generally has a three-layer structure, the outer protective layer is a fluoropolymer layer, and has good environmental corrosion resistance, and the middle layer is a polyester film layer capable of biaxial stretching, and has good insulation properties and mechanical properties. The inner layer is a fluoropolymer layer or a polyethylene-vinyl acetate copolymer layer, which has good adhesion to the packaging material EVA. At present, the preparation methods of the backsheet materials at home and abroad are mostly coated with a polyurethane binder on both surfaces of the PET barrier film, and then respectively combined with a fluorine film and a fluorine film, a fluorine film and an EVA film, a fluorine film and a PE film. The preparation method mainly solves the problem of adhesion between fluorine film and PET film, PET film and EVA (PE) film, but there are still defects: using a staged composite means, that is, first coating and compounding on one surface of the PET film After a film, the other surface of the PET film is coated with another film, the process is more complicated; domestic polyurethane adhesives need to be imported, making the production cost of the solar backing plate too high; due to the polyurethane adhesive For the solvent-based binder, a large amount of organic solvent is required, and the adhesive currently used has a poor adhesion effect and insufficient waterproof performance.
