To improve the status quo of low slurry formation concentration and poor slurry performance of non-stick coal， Herein, Shenhua non-stick coal (SNC) was used as the object of study, and five kinds of sodium polystyrene sulfonate (PSS) dispersants with different lipophilic strengths were selected. The mechanism of the effect of the dispersant lipophilic groups on the slurry formation of SNC was investigated by examining the constitutive relationships between the strength of PSS lipophilic groups and the rheological properties, stability performance, wetting performance and adsorption behavior of SNC coal-water slurry. The results show that the strength of the lipophilic groups of PSS dispersants significantly affects the stability, rheology and apparent viscosity of the non-stick coal slurry. The longer lipophilic chain segments, the increases cross-linking between molecules and the larger spatial potential resistance formed make the slurry more stable. However, the apparent viscosity and rheology of coal-water slurry will be extremely high when the polymerization degree of PSS is 187 because the adsorption amount of dispersant molecules on the coal surface and its adsorption constant KL value increase and then decrease with the increase of PSS polymerization degree. SNC particle surface, which in turn forms uniform water molecule adsorption sites on the coal particle surface and promotes the formation of a uniformly textured hydration film.The SNC coal water slurry prepares with the dispersant content of 0.6% of dry coal powder and the slurry concentration of more than 61% has better slurry performance.
