Wet Surface Modification of Calcium Silicate Hydrate Superfine Powder

  • Received Date: 13 Jan 2009
  • Four kinds of modifiers were chosen to conduct wet modification experiments for calcium silicate hydrate to improve its compatibility with polymer materials.The modifier with the best modification effect was optimally selected to do orthogonal experiments to investigate the effects of modifier quantity,concentration of calcium silicate hydrate in the slurry,and modification temperature and time on surface modification of calcium silicate hydrate.Under the optimal condition,the active index of the modified product increased from 0 to 95%,and the oil absorption value decreased from 86.5 mL/100 g to 69.5 mL/100 g.Infrared analysis shows that chemical adsorption of the optimally selected modifier happens on the surfaces of the calcium silicate hydrate powders,resulting in their organization.
