METHOD FOR THE PRODUCTION OF FILLERS MODIFIED WITH ORGANOSILICON COMPOUNDS, THE FILLERS PRODUCED IN THIS MANNER AND THEIR USE

摘要

A two-stage method for the surface modification of natural or synthetic, oxide or silicate fillers using organosilicon compounds of the formulas: [Rn1(RO)3-nSi-(Alk)m-(Ar)p]2 [S] x or [Rn1(RO)3-nSi-(Alk)m-(Ar)pSCN in which filler and compound are intensively mixed without the addition of further solvents and the homogenized mixture is subjected in a preheated mixer to the hydrophobing reaction.
