AI Technical Summary
Existing non-silicone release agents have shortcomings in electrolyte resistance and high-temperature stability, which makes the release force of the tape fluctuate easily when it is in contact with electrolyte or high-temperature environment for a long time, and the residual adhesion decreases, making it difficult to meet the needs of high-reliability battery production.
A high-performance non-silicone release agent for battery tapes in liquid form is produced by stepwise polymerization and modification with fluorinated monomers. Nano-silica with a surface modified by silane coupling agent is added to form a micro-nano roughness structure and a molecular-level repulsion layer, which improves the wear resistance and electrolyte resistance of the release layer. The production process is simplified by using a low-VOC composite solvent system.
Release force fluctuation is less than 5% under long-term storage or high-temperature environment, and residual adhesion retention rate is higher than 93%, which is significantly better than traditional technology, and meets environmental protection regulations. It also simplifies the production process and reduces energy consumption by 30%.
