VACUUM HEAT-INSULATING MATERIAL AND METHOD FOR MANUFACTURING VACUUM HEAT-INSULATING MATERIAL

摘要

A vacuum insulation panel, which has a high degree of freedom in shape, is capable of stably obtaining an excellent insulating property and has a long lifetime, is provided. A process for manufacturing a vacuum insulation panel (1) includes a step of pressurizing core members (10) under a pressure of at most 1 ×10 6 Pa to form a molded product (12), the core members containing fumed silica with a binder (A') 10a, which includes fumed silica (A) and a binder applied to surfaces thereof; and a step of decompressing and encapsulating the molded product (12) in an outer sheath having an airtight property. A vacuum insulation panel includes an outer sheath (14) having an airtight property; a molded product (12) having core members (10), the core members containing fumed silica with a binder (A'), which includes fumed silica (A) and a binder applied to surfaces thereof; and the molded product (12) being decompressed and encapsulated in the outer sheath (14).
