Abstract:
This manufacturing method of a heat insulating material involves: a coating step in which a coat is formed by coating a coating solution with a coating means that applies a pressure of no more than 1.5 MPA to the coating solution, which is obtained by mixing aerogel particles, a water-soluble polymer having a hydrophobic group and a liquid medium such that the aerogel particles congeal; and a removal step in which at least part of the liquid medium is removed from the aforementioned coat to obtain a heat insulating material.
