Traditional sulfur dispersion suffered from fast precipitation and deterioration. In order to solve the problem, raw materials and the preparation process of traditional sulfur dispersion was improved. The performances of novel sulfur dispersion were analyzed. Then, the novel sulfur dispersion was applied to beater-addition paper board to discuss its effect on performances of paperboard. The results showed that the sulfur dispersion that using glycerol as wetting agent, using NNO as dispersing agent, and using carboxymethyl cellulose sodium as suspending agent has best performance. Compared to traditional sulfur dispersion, novel sulfur dispersion has smaller average particle size of 0.76 um and its uniform charge density increases to -7.8 meq.g-1. The stability of products is also improved .In addition, the sealing paperboard using it as curing agent has higher rebound ratio, smaller compression rate and the overall practical effects are better than traditional sulfur dispersion and common sulfur.
