Abstract

Fillers produced by calcining hydrated silica or water-insoluble silicate in finely-divided form in suspension in a turbulent upwardly-rising current of gases at 500-1200 DEG C. for one second or less (see Group III) are used in butadiene-styrene copolymer compositions. A typical formulation (Example 3) is 100 parts butadiene-styrene copolymer, 50 parts filler, 1,5 parts phenyl-b -naphthylamine, 2 parts dicyclohexylamine, 5 parts zinc oxide, 3 parts stearic acid, 7,5 parts cumarone resin, 2,5 parts polyxylylmethylol ether, 3 parts sulphur, 0,75 part dibenzothiazyldisulphide, and 1 part di-(ortho-toluyl)-guanidine. Specification 866,325 is referred to.ALSO:Hydrated silica or water-insoluble silicate fillers or pigments are calcined to remove bound and free water by suspending the finely-divided fillers in a turbulent upwardlyrising current of gases at 500-1200 DEG C. for one second or less. Preferably, the filler is introduced into the central area of a vortex of hot gas by injecting the solid, or atomizing a suspension, axially into combustion gases introduced, from a combustion chamger, tangentially at 15-150 m/sec. into the lower smaller end of a uniformly tapered vessel. The calcined filler is withdrawn from the upper end to cyclones and should be cooled below 300 DEG C. within 30 mins. Part of the heating gas, or oil, may be introduced axially into the vessel and burnt therein. Residual gases may be recycled and air may be preheated. Specification 866,325 is referred to.
