Title:
断熱シートおよびその製造方法
Document Type and Number:
Japanese Patent JP6738990
Kind Code:
B2
Abstract:
A heat insulation sheet includes, as a substrate, a silica aerogel with low heat conductivity and high mechanical strength In a hydrophobization reaction of a hydrogel, a silane coupling agent having a reactive organic functional group is used to conduct hydrophobization, and, after volatilization of a solvent in a drying step, the temperature is elevated to 100°C or higher that is a reaction-starting temperature, thereby reacting and bonding the reactive functional group and a fiber to each other. This allows prevention of detachment or loss of fine particles of silica xerogel from the unwoven fabric fiber.
