摘要： A suspension for the solvent-free production of silicone resin-bonded papers based on sheet silicates, which consists of:(a) 100 parts by weight of a sheet silicate,(b) 100 to 10,000 parts by weight of water,(c) 0.1 to 5 parts by weight of at least one silane of formula (I):(R'O).sub.a SiR.sub.4-a (I) in which R denotes substituted or unsubstituted hydrocarbon radicals having 1 to 20 carbon atoms and R' denotes C.sub.1-10 -alkyl, aryl, alkylaryl or hydrogen and a assumes a value from 1 to 3, and/or the partial hydrolysis product thereof,(d) 1 to 50 parts by weight of a pulverulent silicone resin of formula (II):(R'O).sub.b SiR.sub.C O.sub.(4-b-c)/2 (II) in which R and R.sup.1 have the abovementioned meaning and b assumes a value from 0 to 0.5 and c a value from 0.7 to 1.3, with the proviso that at least 5 parts by weight of the silicone resin of formula (II) are used per part by weight of the compound of formula (I),(e) 0.01 to 20 parts by weight of a compound catalyzing the hydrolysis and/or condensation of the compounds of formulae (I) and/or (II) and(f) optionally further known additives.
