| Abstract:The low chlorine polyamideamine-epichlorohydrin resin (CPAE) was prepared by modification of traditional PAE with KH-560 and effective post treatment, the new type of environmentally friendly high solid content wet strengthening agent CPAE resin could further improve the chemical bonding between the paper fibers, and the wet tensile index and dry tensile index of the paper could improved simultaneously. Compared with traditional PAE agent, the CPAE wet strength agent could obviously improved the paper dry tensile index by 25.1% from 41.0 N·m/g to 51.3 N·m/g, wet tensile index by 91.1% from 8.11 N·m/g to 15.5 N·m/g, and retention rate of tensile strength up by 52.5% from 19.8% to 30.2% when the CPAE dosage was 1%(on oven fibers). Compared with PAE, the solid content of CPAE increased form 12.5% to 30%. After treatment, the content of organic chtorine decreased from 5% of PAE to 0.5%. |
