Preparation and Water Resistance of the New Water Epellent Agent of Paper Lunch Boxes
In this paper, a kind of sizing synergist,AKD,cationic rosin(CRS) and oil resistance agent were mixed in different proportions, we make it as a kind of new water repellent agent ,and for internal sizing. The best dosage and the composite ratio of the synergist, AKD, cationic rosin and oil resistance agent was discussed mainly in this experiment. And then the copy paper were tested of the substanceweight and contact angle, and compared with the water resistance when the domestic water repellent agent or AKD was added alone. Conclusions of this experiment are following: the optimal conditions were that the mass ratio of AKD and CRS is 6:4, the additive level of AKD and the cationic rosin is 6% (based on dry weight of pulp), the quantity of the sizing synergist is 0.5% , and no oil resistance agent was added, the effect of water resistance is best.
