A method for preparing a laminating adhesive for printing by using a nano-acrylic emulsion
By using seed emulsion polymerization and in-situ nanocomposite technology, nano-silica and organically modified montmorillonite are synergistically modified to prepare a zero-VOC, highly stable, highly transparent, and highly adhesive coating adhesive. This solves the problems of poor environmental performance, weak initial tack, and insufficient water and heat resistance of coating adhesives, making it suitable for high-speed printing production lines and improving product performance and production efficiency.

AI Technical Summary
Existing film adhesive products have poor environmental performance, weak initial tack, insufficient water and heat resistance, uneven nano-dispersion, and low paper-plastic adhesion, which cannot meet the needs of high-speed industrial production.
By employing seed emulsion polymerization and in-situ nanocomposite technology, and utilizing the synergistic modification of nano-silica and organically modified montmorillonite in two phases, and using water as the dispersion medium throughout the process, a printing coating adhesive with zero VOC, high stability, high transparency, and high adhesion strength is prepared.
It achieves zero VOC emissions, rapid curing, resistance to boiling water immersion, high temperature stability at 120℃, strong paper-plastic adhesion, and transparent and glossy film formation. It is compatible with high-speed printing and laminating production lines with a speed of 300m/min or higher, improving production efficiency and product quality.
