Study on the Synthesis Optimization of Paper Wet-Strengthening Resin PAE
The Polyamide Polyamine Epichlorhydrin Resin was obtained by using adipic acid, diethylene triamine and epoxy chloropropane as raw materials. The factors that would affect the properties of PAE resin were considered, including the reaction time, the dosage of the epoxy chloropropane, the injection time of epoxy chloropropane and the soaking time, and the wet strengthening property of PAE resin were studied through experiments. The results are as following: the ratio of epoxy chloropropane to diethylenetriamine is 1:1, the injection time of epoxy chloropropane is 8.5 min, the reaction temperature is 75 °C and the soaking time is 35min~40min. Under the optimum conditions, the PAE has a higher wet-strength and solid content, and its viscosity up to 25~35cp.
