Abstract

The invention discloses a rapid-heating constant-temperature hot compress patch and a preparation method thereof. The rapid-heating constant-temperature hot compress patch comprises a nonwoven fabriccoating layer, an adhesive layer, an automatic-temperature-control heating layer, a power-on circuit and a power source. The automatic-temperature-control heating layer is peripherally coated with thenonwoven fabric coating layer, one surface of the nonwoven fabric coating layer is provided with the adhesive layer, and the outer face of the adhesive layer is provided with a release layer. The automatic-temperature-control heating layer is connected with the power source through the power-on circuit to form electrical connection. The automatic-temperature-control heating layer is prepared from, by mass, 10-30 parts of a base material, 30-60 parts of organic crystals, 30-40 parts of conductive particles and 2-10 parts of a synthesis auxiliary agent. Compared with existing hot compress patches on the market, the rapid-heating constant-temperature hot compress patch has advantages of light weight, softness, portability, high accuracy in temperature control, elimination of scalding causedby overheating and suitableness for the demand of human body hot compress.

Description

technical field [0001] The invention relates to a topical hot compress spirit, in particular to a rapid heating and constant temperature hot compress spirit and a preparation method thereof, belonging to the field of medical hot compress health care. Background technique [0002] Refuling can be used in the adjuvant treatment of rheumatism or rheumatoid arthritis, wind-cold cold, dysmenorrhea, abdominal pain caused by cold, diarrhea and other diseases. It can also be used to protect against cold in cold winter. Most of the raw materials of Refu Ling on the market are iron powder, wood powder, activated carbon, salt, and vermiculite. The iron oxidation reaction is used to release heat, and vermiculite is used to keep warm. The time and temperature of heat release are determined by the oxygen permeability rate of the breathable membrane. If the oxygen transmission rate is high, the heat release time is short and the heat release is large, which is easy to burn the skin; if the...
