A process for the continuous preparation of addition-crosslinking silicone rubbers
from a base composition containing at least one polyvinyl polysiloxane and at least
10% by weight, based on the liquid silicone rubber, of hydrophobicized filler,
by removing the base composition from a container whose volume reduces proportionally
with the amount removed, and conveying the composition by way of a pump with a
positive pressure difference to two further pumps (4) which convey the base
composition onward, so a component A is prepared continuously by admixing at least
one metal catalyst with one stream of the base composition, and a component B is
prepared continuously and simultaneously by admixing the crosslinker and inhibitor
with a second stream of the base composition, where the metal catalyst, crosslinker,
and inhibitor are fed by way of a feed unit which meters in each of the substances.
