Production process of fever cooling patch

The invention discloses a production process of a fever cooling patch, and belongs to the technical field of medicines, and the production process comprises the following steps: step 1, preparing hydrogel feed liquid from the following components in parts by weight: 2-10 parts of carrageenan, 1-8 parts of glucomannan, 1-5 parts of potassium chloride, 1-7 parts of glycerol, 10-70 parts of propylene glycol, 1-10 parts of p-hydroxyacetophenone, 1-10 parts of 1, 2-hexanediol and 880-983 parts of purified water; step 2, pouring the feed liquid into a bottom support; step 3, cooling the feed liquid in the bottom support; and 4, the composite film is heat-sealed on the upper surface of the bottom support. The prepared hydrogel is fast in forming, short in preparation period, resistant to high temperature and moderate in water loss rate during fever abatement, and the fever abatement effect is guaranteed while moisture is preserved; the hydrogel is molded by casting in the bottom support and is suitable for freezing
