[0021] The glove body (1) includes a glove wrist part (103), a glove palm part (102), and a glove finger part (101). It is characterized in that: the glove finger part (101) is connected to one end of the glove palm part (102), the glove wrist part (103) is connected to the other end of the glove palm part (102), and the positions of the glove finger part and the glove wrist part correspond to each other. The glove wrist part, the glove palm part, and the glove finger part are communicated with each other to form the glove body (1).

[0022] The glove is a finger-separated glove, and each has 5 separate long bags for holding fingers as the glove finger part (101). Each part between the inner layer (10) and the outer layer (7) of the glove is integrally injection-molded, and the raw material used

[0023] is a food-grade silicone raw material; each part is the glove wrist part (103), the glove palm part (102), and the glove finger part (101).

[0024] Kitchen gloves are inevitable to have some stains and water stains. The advantage of using food-grade silicone for integral injection molding is that it does not stick to water, does not stick to oil, is easy to clean, and can withstand high temperatures up to 250 °C. The product material is relatively soft and has a comfortable touch.

[0025] The heat-insulating layer (9) is aerogel felt;

[0026] The heat-absorbing layer (8) is a phase-change material flexible film. The phase-change material flexible film is a sorbitol high-density polyethylene composite energy storage material. And this phase-change flexible film can be bent, twisted, and deformed without losing its material properties.

[0027] Take 3g of high-density polyethylene and add it to a three-necked flask, add 30mL of m-xylene, and heat it to 120℃. Then add 4.5g of erythritol, keep the temperature at 120℃, and stir for 2h until the mixture is evenly mixed. Then place the mixture in a constant temperature oven and bake it at 100℃ to constant weight to obtain a sugar alcohol high-density polyethylene composite energy storage material.

[0028] The heat absorption unit (6) is a high enthalpy phase change heat storage powder.

[0029] The high enthalpy phase change heat storage powder is a sugar alcohol cellulose composite energy storage material; the phase change temperature of the phase change heat storage powder is 100°C and the enthalpy value is 300kJ / kg.

[0030] Prepare an erythritol aqueous solution with a mass percentage concentration of 30%; prepare a hydroxypropyl cellulose (weight average molecular weight of 100,000) aqueous solution and a polyvinyl alcohol (weight average molecular weight of 100,000) aqueous solution with a mass percentage concentration of 2%, and blend them in a mass ratio of 2:1, purge with nitrogen to remove the air in the system, then add glutaraldehyde crosslinking agent, the mass ratio of which to hydroxypropyl cellulose is 5:2, and fully react in a nitrogen atmosphere for 3 hours to obtain a modified polymer aqueous solution; add erythritol aqueous solution to the modified polymer aqueous solution, wherein the mass ratio of the modified polymer to erythritol is 10:90, and stir well to form a homogeneous aqueous solution; vacuum degas a certain amount of the prepared aqueous solution and evenly coat it on a polytetrafluoroethylene-based plate, and dry it at 80°C for 6 hours to obtain a sugar alcohol cellulose composite energy storage material.

[0031] The finger of the glove is provided with one or more anti-slip protrusions (2), and each corresponding heat absorption unit has a size of 1cm*1.5cm*0.3cm; the palm of the glove is provided with one or more anti-slip protrusions (2), and the area covered by the corresponding heat absorption unit accounts for 90% of the total palm area of ​​the glove.

[0032] The outer surface of the glove wrist portion (103) is provided with a tightening belt (3), and the end of the tightening belt (3) away from the wrist portion (103) is provided with a Velcro round fleece surface (4), and the wrist portion (103) is provided with a Velcro burr surface (5) bonded to the Velcro round fleece surface (4).

[0033] Compared with traditional materials, aerogel can achieve better results with lighter mass and smaller volume. Aerogel has the advantages of heat insulation and high temperature resistance. The combination of the aerogel used and the phase change material can greatly reduce the thickness of the kitchen heat-insulating gloves. The heat generated by the hot cooking utensils is first absorbed by the phase change material. If the heat generation is large, the aerogel will isolate the remaining heat, keeping the hand at a suitable temperature all the time. Under the action of the flexible film of the phase change material, the whole glove can have the heat absorption function and flexibility. According to the hand muscle distribution and joint positions, heat absorption units containing high-enthalpy phase change heat storage powder are designed, which greatly increases the heat resistance duration of the gloves without affecting the use flexibility. Such a combination can make the gloves have a long heat resistance time, and at the same time, compared with common heat-insulating gloves, can greatly reduce the thickness of the gloves, thus increasing the flexibility of the user's hand when using.
