More Information
Summary:Provided is a latex-bound silica composition, which shows a low powder silica scattering degree, improves work environment during the preparation thereof, and has excellent dispersibility while maintaining other physical properties. The latex-bound silica composition is obtained by the method comprising the steps of: coating 3-15 parts by weight of a silica coating agent onto 100 parts by weight of silica; binding 80-150 parts by weight of a latex-containing binder solution onto 100 parts by weight of the coated silica; and drying the latex-bound silica at 110-150 deg.C to a water content of 5-10 wt%. The silica coating agent is obtained by mixing 60-70 wt% of a silane coupling agent, 10-20 wt% of a surfactant, 10-20 wt% of wax and 10-20 wt% of processing oil.
