Compared with traditional materials, aerogel can achieve better results with lighter weight and smaller volume. Aerogel has the advantages of heat insulation and high temperature resistance. The combination of the aerogel and the phase change material can greatly reduce the thickness of the kitchen insulation gloves. The heat generated by the hot kitchen is first absorbed by the phase change material. If the heat generation is large, the aerogel will The waste heat is isolated to keep the hand at a suitable temperature all the time, and under the action of the flexible film of phase change material, the whole glove can have heat absorption function and flexibility. The heat absorption unit containing the high enthalpy phase change heat storage powder greatly increases the heat resistance time of the glove without affecting the flexibility of use. This combination can greatly reduce the thickness of the gloves compared to common thermal insulation gloves while the gloves have a longer heat-resistant time, thereby increasing the flexibility of the user's hands during use.
