| Abstract:Maleic anhydride was used to prepared high solid content unsaturated PAE resin by replacing part of the adipic acid, the structure of the PAE resin was defined by chemical analysis, infrared spectroscopy, and other means. The influrence of amount of maleic anhydride, its adding methods, reaction temperature, reaction time and other factors on the properties of PAE was also discussed. The results showed that: under the nitrogen atmosphere with n(MAH and AA)∶n(DETA)=1∶1.05, maleic anhydride dorage was 20% of that of dicarboxylic acid, p-toluenesulfonic acid amount was 0.7%, reaction time was 5 h at 160℃,the prepared intermediate PPC had a suitable viscosity. Under the conditions of n(ECH)∶n(DETA)=1.5∶1, m(PPC)∶m(pre-water)=1∶1, reacting for 3 h at 65℃, the prepared unsaturated PAE had stronger stability. The wet strength was 24.4% when the dosage of PAE was 1.5%. |
