  Abstract

Novel cationic macromolecular emulsifier (PD emulsifier) and anionic macromolecular emulsifier (PA emulsifier) were synthesized with acrylate monomer and E-TPA (self-made molecular weight regulator), which were further used to prepare cationic sizing agent (PD-sizing agent) and anionic sizing agent (PA-sizing agent) respectively. On the other hand, ETPA was synthesized with epoxy resin and S,S'-bis(慣,慣'-dimethyl-慣''-acetic acid)-trithiocarbonate. Because the performance of sizing agent and macromolecular emulsifier was affected by E-TPA with epoxy resin, the critical micelle concentration, solubilization and molecular weight of the emulsifier with various E-TPA dosages were studied, while the water resistance and mechanical properties of sizing paper were further researched. The results indicate that the water resistance and mechanical strength can be enhanced with epoxy resin, under the premise that the particle size of the sizing agent is small enough. The PD-sizing agent with the PD emulsifier of which the amount of E-TPA is 11.63 wt% shows the best sizing properties with folding endurance of 19, bursting strength of 211 kPa, tensile strength of 72.77 kN/m and the water absorption (cobb) of 54.23 g/m2. The PA-sizing agent with the PA emulsifier containing 11.63 wt% of E-TPA documents the best sizing properties with tensile strength of 61.49 kN/m, folding endurance of 14, bursting strength of 185.67 kPa and the cobb of 47.88 g/m2.
