- Abstract
In this paper, the pulp molding was prepared with bamboo chemical pulp and softwood chemical pulp, and the modified fluorine free acrylate copolymers were coated on the surface of the pulp molding packaging materials by Meyer rod coating or dip coating. The mechanical properties, water and oil resistance of the pulp molded packaging material before and after treatment were evaluated. The results showed that, compared with the molding without any additives, the mechanical properties of pulp molding packaging materials using three acrylate copolymers were slightly lower, and the water resistance and oil resistance were enhanced significantly. Among them, the Cobb value was reduced from 508 g/m² (without additives) to 15~18 g/m², the water contact angle remained at a high level after 5 min, and the oil resistance grade (Kit value) could reach 8 or more, but its hot water and hot oil resistance were relatively poor. The Cobb value of pulp molding packaging material was further decreased to 0. 9~2. 1 g/m² by using the starch-modified fluorine-free acrylate copolymer, the change value of water contact angle within 5 min was only 4. 0°~8. 2°,and the oil-proof grade could reach to more than 10 and its hot water and hot oil resistance were significantly improved.
