Thermal insulator and method for producing same

Abstract

Provided is a thermal insulator B formed by bonding a plurality of aerogel particles A with adhesive 2 and a method for producing the same. The aerogel particles A have an average particle size of 500 μm or more. The adhesive 2 exists as particles on surfaces of the aerogel particles A. A ratio (adhesive/aerogel particle) of an average particle size of the adhesive 2 to the average particle size of the aerogel particles A falls within a range of 1/200 to 1/10. For producing the thermal insulator B, the adhesive 2 is made of an adhesive powder including thermosetting resin or thermoplastic resin. Obtained thermal insulator B has an improved strength and is excellent in thermal insulating properties.
