PROCESS FOR PREPARING A PULVERULENT RUBBER MIXTURE |
摘要 |
<p>Discrete, finely divided, tack-free elastomer particles are prepared from a filler-containing aqueous elastomer emulsion containing an aqueous emulsion of an elastomer dissolved in a volatile inert organic solvent having an emulsifying amount of a quaternary ammonium salt cationic surfactant and an aqueous suspension or dispersion of a solid, finely divided elastomer filler, which process comprises gradually introducing the filler-containing aqueous elastomer emulsion into an aqueous alkali silicate solution while maintaining said solution at a pH greater than 2 and simultaneously evaporating the organic solvent to form discrete, finely divided, tack-free elastomer particles.</p> |
