Abstract

PURPOSE: To manufacture a heat-resistant and water-resistant insulating tape useful for the insulation of a driving DC motor of a vehicle, in a few steps, by adding a specific coupling agent together with a catalyst to a binder solution.
CONSTITUTION: An insulating tape is prepared by treating a substrate composed of a glass cloth and a collected mica sheet, with ha binder solution containing a catalyst and a coupling agent of the formula R'WSi(OR)n or R'WTi(OR)n. The OR group is hydrolyzed to OH by a trace of water in the solution, and adsorbed to the surface of the glass or the mica. Since the other end of the coupling agent is a non-polar organic functional group, the coagulation of the catalyst can be prevented. The wate-resistance of the insulation is improved because the OH group of the coupling agent forms strong chemical bond between the surface of the glass or the mica, and the interface of the coupling agent and the silicone resin is nearly non- polar. The amount of the coupling agent is usually 0.2W0.5 % of the substrate.
