Embodiment 1
[0031] refer to figure 1 , a self-heating type thermal paste, comprising a vacuum outer packaging tape 1 made of PET material, an inner packaging bag 2 made of non-woven fabric, and a heating material 3 is housed in the inner packaging bag; one side of the inner packaging bag 2 is provided with A gelatin layer 4, and a protective film 5 is provided on the gelatin layer.
[0032] Preparation of heating materials: 20.8 g of secondary reduced iron powder, 1.2 g of sodium chloride, 2.0 g of activated carbon powder, 8 g of 300-400 mesh vermiculite, 0.8 g of wood powder, 7.2 g of tap water, and a total mass of 40 g.
[0033] The heating temperature can last for 16 hours at 40-50 ℃.
Embodiment 2
[0035] The structure of the self-heating type thermal sticker is the same as that in Example 1.
[0036] Preparation of heating materials: 21.6 g of secondary reduced iron powder, 0.8 g of sodium chloride, 1.4 g of activated carbon powder, 7.4 g of 300-400 mesh vermiculite, 1.2 g of wood powder, 7.6 g of tap water, and a total mass of 40 g.
[0037] The fever temperature can last for 17 hours at 40-50 ℃.
Embodiment 3
[0039] The structure of the self-heating type thermal sticker is the same as that in Example 1.
[0040] Preparation of heating materials: 22.4 g of secondary reduced iron powder, 0.8 g of sodium chloride, 1.6 g of activated carbon powder, 8 g of 300-400 mesh vermiculite, 0.4 g of wood powder, 6.8 g of tap water, and a total mass of 40 g.
[0041] The fever temperature can last for 18 hours at 40-50 ℃.

Abstract
The invention provides a self-heated type thermal paste which comprises a vacuum external packaging bag and a breathable internal packaging bag. The internal packaging bag is filled with a heating material; one side of the internal packaging bag is provided with a gelatin layer; the gelatin layer is provided with a protecting film; the heating material is prepared from secondarily-reduced iron powder, sodium chloride, vermiculite, wood powder, active carbon powder and tap water at a certain proportion. Because the vermiculite is used as the heat preserving and insulating material of the self-heated type thermal paste, the heating time of the self-heated type thermal paste is prolonged greatly, and because the wood powder is used to prepare the self-heated type thermal paste, the heat preserving performance and the water retaining performance of the self-heated type thermal paste are improved effectively. A large number of experiments show that the self-heated type thermal paste can be heated to 40-50 DEG C, and the heat can be preserved for about 20 hours. In addition, the self-heated type thermal paste has the characteristics of low cost, easily-available raw materials, simple formula, quick long-time heating and balanced heat and can be used by people who can not tolerate cold and people who work or do activities outdoors in cold winter to keep warm.
Description
technical field [0001] The invention relates to a self-heating thermal paste with long heating time, simple formula and low cost. Background technique [0002] Self-heating heat stickers have gradually become the main equipment for outdoor heating and heating due to their safety, long heating duration, and convenient use. Moreover, the heat it continuously emits can relieve pain caused by arthritis, frozen shoulder, low back pain, rheumatism and rheumatoid, and has the effect of promoting blood circulation and removing blood stasis. [0003] Self-heating products currently on the market have disadvantages such as unbalanced heat and short heating time. For example, the imported product "Wen Xin Kuai He" brand, produced by Hakuen of Japan Co., Ltd. and distributed by Hakuen Household Products (Shenzhen) Co., Ltd., has a continuous heat preservation time of 12 hours. [0004] CN 101108150A discloses a self-heating warm bag, in which the self-heating agent is composed of iron...
