| Abstract: |
| Sodium silicate was solidified with PA and was coated on corrugating paper as a surface sizing agent to improve ring crush and burst strength of corrugating paper. The effect of the compound sizing agent on the main strength indexes of the paper was studied. The water resistance of the sized corrugating paper was characterized by Cobb value and the mechanism of surface water-resisting property was analyzed. Compared with conventional surface sizing agents, the compound sizing agent which has a higher solid content, lower viscosity, coating content is easily controlled and coated paper has higher stiffness. The results indicated that burst index and ring crush of the coated corrugating paper was increased by 35% and 2.2 times, respectively． |
