The invention relates to a self-heating hot compress material composition, a self-heating hot bag, and a preparation method thereof. The hot compress material composition comprises: (a) reduced iron powder, sodium chloride, and active carbon; (b) 5-700 mesh wormwood powder; (c) a sustained-release agent and a water retention agent; and (d) water. According to the invention, wormwood is added into the self-heating hot compress material, such that volatile matters with illness-dispelling effect in wormwood is effectively combined with the self-heating hot compress material. A proper heating temperature and a proper heating time are utilized, such that a wormwood hot-moxibustion health-care function is fully utilized. Also, a specially shaped protective gear shape consistent with a human joint is adopted, such that a position requiring hot compress can be heated, and the traditional Chinese volatile component with a certain treatment effect can penetrate into the position requiring hot compress.

The invention discloses a disposable self-heating health care patch having a low-temperature solid-solid phase transition temperature control characteristic. In the heating material, a low-temperature solid-solid phase transition material is added; the heating material consists of iron powder, activated carbon, salt, vermiculite and super absorbent resin; the low-temperature solid-solid phase transition material consists of Mg(NO3)2.6H2O and Al(NO)3.9H2O or consists of Mg(NO3)2.6H2O and MgCl2.6H2O or consists of pentaerythritol and neopentyl glycol. According to the phase transition characteristic of the low-temperature solid-solid phase transition material, the disposable self-heating health care patch has the characteristics of stable and uniform heating, controllable heating temperature, effective prevention of low-temperature burn, and safety in use.

Self-heating material

Disclosed is a self-heating thermal-insulation multilayer film comprising a structure of at least three layers, which from outside to inside are respectively: an outer layer ( 1 ) formed of an air permeable material; a heat-generating layer ( 2 ) loaded with heat-generating composition ( 21 ) that generates heat on contact with air, at least an upper sealing surface of the heat-generating layer that is in contact with the outer layer being formed of an air permeable material; and an thermal-insulation layer ( 3 ) formed of a material having waterproof and thermal-insulation properties. The present self-heating thermal-insulation film is structurally simple, is not constrained by environmental resources, does not require energy supply from an external energy source, is safe and stable, uniformly generates heat, and can effectively prolong heating time and reduce peak heating temperature. The present self-heating thermal-insulation film can be manufactured into a three-dimensional face mask, a face mask, or an eye mask.

The present self-heating thermal-insulation film can be manufactured into a three-dimensional face mask, a face mask, or an eye mask for use on facial skin to improve blood circulation, enlarge facial pores, so as to clean skin dirt and sebaceous secretion. When used in combination with a traditional nourishing face mask or skincare product, the absorption of the effective ingredients in the traditional face mask or skincare product is improved, so the amount of skincare product used is reduced and skincare effect is enhanced. In addition, the use is safe and low-cost.
