The invention relates to the technical field of heat insulation materials, in particular to an improved energy-saving environment-friendly constant-temperature bag. The constant temperature bag is formed by bonding two parts of silicon dioxide aerogel and a rubber foaming layer, and each part has better heat preservation performance, so that double heat preservation is realized. The formation of the cross-linked network is flexibly regulated and controlled by changing conditions so as to achieve better mechanical property and improve the practicability of the constant-temperature bag. Meanwhile, the thermal insulation bag can be recycled, and energy conservation and environmental protection are facilitated. |
