Mold release agent solution for environment protection type capacitor and preparation method thereof

Abstract

The invention relates to a capacitor mold release solution and the preparation method thereof. The environment friendly capacitor mold release solution comprises a mold release solution and the solvent thereof, wherein, the mold release solution adopts organosilicon, the solvent adopts gasoline with the octane value being not lower than 95 percent, and the weight proportion of the organosilicon and the gasoline is (3 to 5):100. The environment friendly capacitor mold release solution adopts the preparation method that the organosilicon and the gasoline are weighed according to the weight proportion of (3 to 5):100, and then stirred for 10 to 15 minutes in a magnetic stirrer, to be perfectly mixed. The mold release solution has good, uniform and smooth film formation effect when being sprayed on the lead-out line of a capacitor, the welding performance and the cured epoxy resin of the lead-out line are not influenced, the adhesive force to the epoxy resin is low, the preparation is convenient, and the solution is nontoxic.

Description

technical field [0001] The invention relates to a capacitor release agent solution and a preparation method thereof. Background technique [0002] In the manufacture of film capacitors, it is necessary to use epoxy resin as its outer encapsulation. Due to the excellent adhesion of epoxy resin, it is inevitable to coat the lead-out wire of the capacitor with epoxy resin during product encapsulation. However, after the lead wire of the capacitor is wrapped with epoxy resin, the welding performance of the product cannot be satisfied. Therefore, the capacitor needs to be coated with a release agent on the lead wire before dipping epoxy resin. The selection of release agent and solvent is very important. It is required that after the lead-out wire is coated with release agent, the lead-out wire is uniform and smooth, has good film-forming property, has no effect on the cured epoxy resin, and has low adhesion to the resin. Moreover, it is required to be safe in operation, non-t...
