Application Study of Cationic Polymethyl Acrylate Emulsion as Papermaking Sizing Agent

Abstract:

The cationic polymethyl acrylate (CPMA) emulsion which was prepared with no soap emulsion polymerization was used with petroleum resin sizing agent in bleached wheat straw pulp and wood pulp as papermaking sizing agent. It was showed that by the experimental results that when the dosage of composite sizing agent composed of CPMA emulsion and anionic petroleum resin sizing agent was 0.2% absolute dry pulp, sizing degree and white degree of handsheet made of bleached wheat straw pulp were improved 33% and 5.2%ISO respectively. It was also showed that when the dosage of composite sizing agent was 0.2% absolute dry pulp, sizing degree and white degree of handsheet made of wood pulp were improved 37% and 4.2%ISO respectively.
