PREPARATION AND SIZING PERFORMANCE OF BUTYLAMINE MODIFIED LAPONITE STABILIZED ASA EMULSIONS
Solid stabilized emulsions can avoid detrimental effects of surfactant. In this paper, ASA emulsions are prepared by emulsifying ASA using butylamine modified Laponite particles as emulsifier and stabilizer, and the sizing performance, hydrolysis stability of the prepared emulsions are investigated. The results show that stable ASA emulsion is obtained as the pH of aqueous phase, Laponite to ASA mass fraction, butylamine to Laponite mass fraction are 6.0, 1.5％ and 2.0％, respectively. The ASA emulsion shows high sizing performance but low hydrolysis stability. The introduction of alum remarkably enhances the sizing efficiency of the ASA emulsions, and the ASA emulsions can develop a rather high sizing degree for paper without retention aid at the presence of high amount of alum.
