本发明涉及太阳能组件封装领域，具体地，涉及一种密封胶带组合物，由该组合物制成的密封胶带，和密封胶带在制备双玻璃光伏组件中的用途。The present invention relates to the field of solar module packaging, and in particular to a sealing tape composition, a sealing tape made of the composition, and a sealing tape for use in preparing a dual glass photovoltaic module.
背景技术Background technique
无边框双玻璃光伏组件的边缘需要很好地密封，丁基橡胶是较好的一个选择，用以隔绝空气中的湿气和氧气，但是现有的丁基橡胶密封胶带存在如下问题：工艺使用温度过高(120度以上)，与玻璃的粘接强度不够高(<7N/cm)。这是因为常规的丁基橡胶，为了使得丁基密封胶带本身具有较好的弹性和合适的硬度，一般都采用硫化后的丁基橡胶作为密封介质，由于丁基橡胶的不饱和度较低，硫化速度慢，因此一般需要在较高温度下，方可进行硫化。即现有技术是采用硫化的丁基橡胶作为密封胶带，通过较高的温度热熔以及固化来实现双层玻璃之间的粘结的。The edge of the borderless double-glazed PV module needs to be well sealed. Butyl rubber is a better choice to isolate moisture and oxygen from the air, but the existing butyl rubber sealing tape has the following problems: process use If the temperature is too high (above 120 degrees), the bonding strength with the glass is not high enough (<7 N/cm). This is because the conventional butyl rubber, in order to make the butyl sealing tape itself have better elasticity and suitable hardness, generally uses the butyl rubber after vulcanization as a sealing medium, because the butyl rubber has low unsaturation, The vulcanization rate is slow, so it is generally required to cure at a higher temperature. That is, the prior art uses a vulcanized butyl rubber as a sealing tape to achieve bonding between the double glazing by high temperature hot melting and curing.
另外，现有的文献还报道了，以丁基橡胶接枝硅烷偶联剂作为玻璃用密封胶的主料，且该玻璃用密封胶还含有石油树脂、酚醛树脂、分子筛等辅料，但是，该玻璃用密封胶在较低温度下的弹性较低，且与玻璃的粘结性也不好。In addition, the prior art also reports that a butyl rubber grafted silane coupling agent is used as a main component of a glass sealant, and the glass sealant further contains an auxiliary material such as a petroleum resin, a phenol resin, a molecular sieve, etc. The glass sealant has low elasticity at lower temperatures and poor adhesion to glass.
因此，现在急需一种在较低温度下与玻璃的粘结性较好的密封胶。Therefore, there is an urgent need for a sealant which has good adhesion to glass at a relatively low temperature.
