Abstract

PURPOSE:To obtain a low wet permeability by using 50-20pts.wt. of glass flake or mica for 100pts.wt. of epoxy resin, 80pts.wt. of curing agent, 1pt.wt. of curing catalyst, and 1pt.wt. of epoxy silane coupling agent. CONSTITUTION:100pts.wt. of Araldite, 80pts.wt. of methyltetrahydrophthalate anhydride as a curing agent, 1pt.wt. of 2-ethyl-4-methylimidazole as a curing catalyst, and 1pt.wt. of epoxy silane coupling agent are mixed. Further, 50- 200pts.wt. of a filler which has at least one of glass flake and mica of 1-3mm. mesh and 60-80 of aspect ratio is mixed to form a coating material. Thus, a low wet permeable coating can be formed, thereby omitting a can of an underwater motor.

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a moisture-resistant coating material for the surface of a submersible mode mold, for example, by coating the inner circumferential surface of a molded stator of the submersible mode with an LC coating. The present invention relates to a composition of a coating material that can omit the installation of a can provided on the inner peripheral surface and can sufficiently prevent moisture permeation.

An underwater mode, for example, its stator has a structure as shown in Fig. 1, and the stator core l, the stator winding attached to it, its coil end λ, etc. are molded. It is molded with resin, such as polyester resin or vinyl ester resin, and its outer periphery is usually surrounded by a stainless steel frame (not shown), and the inner periphery of the stator is covered with a thin stainless steel can 3. ing. However, antifreeze is generally filled inside the can 3 to lubricate the thrust bearing. Therefore, the above can 3 is
One of the purposes is to prevent this antifreeze from infiltrating the mold splinter.
