Description

一种用于硅凝胶的粘结促进剂Adhesion promoter for silicone gel 技术领域Technical field

本发明涉及一种用于硅凝胶的粘结促进剂，特别涉及一种用于提高硅凝胶粘度的粘结促进剂，属于胶粘剂技术领域。The invention relates to an adhesion promoter for a silicone gel, in particular to an adhesion promoter for increasing the viscosity of a silicone gel, and belongs to the technical field of adhesives.

背景技术Background technique

在工业界中，可适用于透明光学元件上的粘接剂有环氧树脂粘结剂、橡胶型粘结剂、改性丙烯酸树脂粘结剂、聚氨酯粘结剂等材料。In the industry, adhesives which can be applied to transparent optical elements include epoxy resin adhesives, rubber type adhesives, modified acrylic resin adhesives, and polyurethane adhesives.

环氧树脂的缺点在于耐黄变性能比较差，同时，其抗开裂和冲击的性能也有欠缺。橡胶型粘结剂的缺点是储存稳定性差。聚氨酯粘结剂缺点是耐温性比较差，高温下易水解。目前被广泛使用的触摸屏用OCA水胶由于成本和售价太高，而且工艺繁琐，有比较大的局限性。硅凝胶虽然具有较好的透明度，但是因其粘性低而无法直接用作透明光学元件的粘结剂。The disadvantage of epoxy resin is that the yellowing resistance is relatively poor, and at the same time, its resistance to cracking and impact is also lacking. A disadvantage of the rubber type adhesive is poor storage stability. The disadvantage of polyurethane binders is that the temperature resistance is relatively poor and it is easy to hydrolyze at high temperatures. OCA water gel for touch screens, which are currently widely used, has relatively large limitations due to the high cost and price, and the cumbersome process. Although silicone gel has good transparency, it cannot be directly used as a binder for transparent optical elements because of its low viscosity.
