Document Type and Number:
WIPO Patent Application WO/2018/002970
Kind Code:
A1
Abstract:
This method for producing an insulating structure for covering the outer surface of an object to be insulated is provided with: a taping step (S01) in which the outside of the object to be insulated is taped with a main insulating tape to form an insulated part; a vacuum drawing step (S03) which is performed after the taping step, and in which the taped object to be insulated is subjected to vacuum drawing; and an impregnation step (S04) which is performed after the vacuum drawing step, and in which a nanoparticle-containing impregnating macromolecular polymer with which nanoparticles have been kneaded is injected into the insulated part to impregnate the insulated part therewith.
