Resumen de: US12460058B1
The invention discloses a high-transparency, low-temperature processable cellulose acetate film and its preparation method. The high-transparency cellulose acetate film comprises, by weight percentage, the following raw materials: 75-85 parts of modified cellulose acetate, 12-20 parts of plasticizer, 2-6 parts of transparency agent, where the plasticizer and transparency agent are both composite additives. The preparation process involves uniformly blending all raw materials, followed by uniform mixing and drying, extrusion, granulation, drying, and casting, to obtain a high-transparency cellulose acetate film. The cellulose acetate film prepared by the above method utilizes the synergistic effect of the specific plasticizer and transparency agent, which not only significantly reduces the processing temperature but also results in a film with high light transmittance and low haze. The film exhibits good extensibility and flexibility, excellent antibacterial properties, and the process is simple, time-saving, and efficient, making it suitable for large-scale industrial production.
