Research on polyester resin for low temperature fusing toner
The long-chain flexible dicarboxylic acid monomer(DSA)was introduced into polyester resin,and the low-temperature fixing polyester resin for toner was prepared.The effects of DSA addtion on the rheological properties,thermal properties,molecular weight size and distribution,charge weight,charge stability and low temperature fixation of polyester resin and prepared toner were studied by using melt index meter,differential scanning calorimeter,capillary rheometer,gel permeation chromatograph,charge capacity tester,optical densitometer and friction tester.The results indicated that the introduction of a certain amount of DSA could reduce the softening temperature and molecular weight of the resin,increase the acid value of the resin,thereby improving the low-temperature fixing performance and electrical performance of polyester resin,and obtaining high-quality printed images.
