Abstract
The present invention discloses a preparation method and recycling method for degradable and recyclable paper plastics with water resistance and high-strength. By coating cyclic carbonate and amine compounds on paper, these compounds penetrate the paper's fiber structure, followed by curing treatment, resulting in a recyclable, degradable, and reprocessed paper plastic material with water resistance and high-strength. This method involves coating only cyclic carbonate and amines onto the paper, which, after heating, yields the paper plastic. The invention offers versatility, enhancing various paper types with improved mechanical properties, temperature resistance, water resistance, and solvent resistance while maintaining degradation capability. The paper plastic exhibits excellent self-healing, plasticity, degradation, and reprocessing properties. The process method is straightforward and user-friendly, making it suitable for industrial-scale production.
