Title:
VACUUM SOUNDPROOFING THERMAL INSULATOR, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/153389
Kind Code:
A1
Abstract:
The present invention relates to a vacuum soundproofing thermal insulating material, and the main objectives thereof are to provide a vacuum soundproofing thermal insulator with which propagation of heat and sound through a supporting portion which supports a vacuum layer is reduced, to provide a vacuum soundproofing thermal insulator having the function of improving soundproofing performance and heat management performance, and to provide a method for manufacturing a vacuum soundproofing thermal insulator. The present invention achieves these objectives by providing, in the main body of the vacuum soundproofing thermal insulator, at least any one of a supporting portion employing magnetic force, having little propagation of heat and sound, a supporting portion and a peripheral edge portion with which a reduction in the propagation of heat and sound compared with the past is achieved structurally, and a supporting portion having the function of opening and closing a heat and sound propagation pathway, to obtain a vacuum soundproofing thermal insulator in which at least any one of soundproofing properties, heat management performance, and a range of utilization is increased compared with the past, and by manufacturing the vacuum soundproofing thermal insulator using a space in which pressure has been taken into consideration, and/or by three-dimensional molding, in order for the vacuum soundproofing thermal insulator to be produced with good performance and in a reasonable manner.
