Abstract
The invention concerns an improvement in the process for the production of dispersions of diorganopolysiloxanes and lubricant-acting inorganic silicates in water, whereby these dispersions contain, in addition to the above-mentioned substances, lecithin and nonionic emulsifiers, as well as solvents, ionic emulsifiers, lubricants other than inorganic silicates and diorganopolysiloxane, bactericides, fungicides, thickeners, antifoaming agents, rust inhibitors and dyes. The improvement is achieved by emulsifying the lecithin, nonionic emulsifier and water with each other before this mixture is mixed with at least 80% by weight of the diorganopolysiloxane contained in the finished dispersion, and, optionally, lubricants other than inorganic silicates and diorganopolysiloxanes. Furthermore, the invention concerns the application of the dispersions produced according to the invention as release agents, especially as inner tire release agents.
