Research on Preparation of Cationic Polyacrylate Emulsion Paper Strengthening Agent

Abstract:

Strengthening agent of cationic polyacrylate emulsion was prepared through semi-continuous seeded pre-emulsion processes. By single factor experiment, investigated the factors which influence on properties of emulsion, such as the proportion of hard and soft segment monomer, the dosage of AM, DMDMAC, emulsifier and initiator, reaction time and temperature, addition time and other factors. The results show that the emulsion has a good enhancement when the monomer ratio of St: MMA: BA is 2:1:3, initiator dosage is 0.7%, the dosage of emulsifiers, AM and DMDMAC are 6%, the amount of protective colloid is 0.3%. Compared to the strength performance between paper with added emulsion and blank paper, find that the performance of paper with added emulsion polymer gets different improves: paper quantitative increase 4.08%, folding strength degree improves 66.67%, tearing degree improves 356.52%, ring compressive strength improves 50.00%, tensile strength improves 44.11%, and bursting strength improves 50.88%
