Embodiment 1

[0042] A disposable self-heating health patch with the characteristics of low-temperature solid-solid phase change temperature control. Low-temperature solid-solid phase change material is added to the heating material. The heating material is composed of iron powder, activated carbon, salt, vermiculite and high water absorption Resin composition.

[0043] In parts by weight, the specific proportioning is,

[0044] Iron powder: 100 parts;

[0045] Activated carbon: 5-15 parts;

[0046] Salt: 50-70 parts;

[0047] Vermiculite: 40-70 parts;

[0048] Super absorbent resin: 1-8 parts;

[0049] Low-temperature solid-solid phase change material: 5-25 parts.

[0050] Among them, the low-temperature solid-solid phase change material refers to a solid-solid phase change material with a phase transition temperature lower than 65°C, which has a composition of Mg(NO 3 ) 2 ·6H 2 O and Al(NO) 3 9H 2 O composition, the Mg(NO 3 ) 2 ·6H 2 O accounts for 40%-60% of the total weight...

Embodiment 2

[0058] A disposable self-heating health patch with low-temperature solid-solid phase change temperature control characteristics, other technical features are the same as in Example 1, the difference is that the low-temperature solid-solid phase change material is made of 53% Mg(NO 3 ) 2 ·6H 2 O and 47% Al(NO) 3 9H 2 O composition. Experiments have shown that 53% of Mg(NO 3 ) 2 ·6H 2 O and 47% Al(NO) 3 9H 2 The phase transition temperature of the material after O mixing is 61 °C.

[0059] The invention utilizes the characteristics of phase change heat storage of low-temperature solid-solid phase change materials, and is applied to disposable self-heating health care stickers, so that the temperature of the disposable self-heating health care stickers is controllable, the heating temperature curve is stable, and the heating temperature is uniform and stable. The user feels comfortable, and can effectively prevent low-temperature burns and burns caused by improper temper...

Embodiment 3

[0061] A disposable self-heating health patch with low-temperature solid-solid phase change temperature control characteristics, other technical features are the same as in Example 1, the difference is that the low-temperature solid-solid phase change material is made of Mg(NO 3 ) 2 ·6H 2 O and MgCl 2 ·6H 2 O composition, the Mg(NO 3 ) 2 ·6H 2 O accounts for 50%-60% of the total weight of the low-temperature solid-solid phase change material, and the MgCl 2 ·6H 2 O accounts for 40%-50% of the total weight of the low-temperature solid-solid phase change material.

[0062] Experiments have shown that Mg(NO 3 ) 2 ·6H 2 O and MgCl 2 ·6H 2 The phase transition temperature of the material after O mixing is about 58-59 °C. The invention utilizes the characteristics of phase change heat storage of low-temperature solid-solid phase change materials, and is applied to disposable self-heating health care stickers, so that the temperature of the disposable self-heating health...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of medical care, and in particular relates to a disposable self-heating health patch with the characteristics of low-temperature solid-solid phase transition temperature control. Background technique [0002] Disposable self-reactive heating products, also known as hot compress paste, hot compress spirit, hot compress bag, hot compress powder, warm baby, portable warm, cold pain music, hot paste, hot pack, ironing paste, hot iron paste, moxibustion paste, warm Gong Bao... wait. Self-heating health patch products use iron powder, activated carbon, inorganic salts, water, vermiculite, etc. to independently undergo chemical exothermic reactions with oxygen in the air to achieve the effects of warming collaterals, dispelling wind, dispelling wind and cold, promoting blood circulation and relieving pain. It has been widely used in the treatment of pain patients caused by wind and cold, such as cervical spondylos...
