Embodiment 1

[0030] A recyclable antipyretic patch, characterized in that it includes a backing layer, an antipyretic layer and a protective layer, the antipyretic layer is located between the backing layer and the protective layer; the antipyretic layer is made of polyurethane material;

[0031] The preparation method of described polyurethane material is, comprises the following steps:

[0032] Step 1: Pretreat polyethylene glycol 10000 and polyethylene glycol 6000 first; after pretreatment, mix 75g polyethylene glycol 10000, 25g polyethylene glycol 6000 and 80g solvent N,N-dimethylformamide Put it into the reaction vessel and stir to mix. After mixing evenly, raise the temperature of the reaction vessel to 90°C, then add 3g of 1,4-butanediol, 1g of 2,2-dimethyl-1,3-propanediol, 1g of 1,2,3 - Hexatriol, 18g of diphenylmethane diisocyanate, 2g of 3-isocyanatopropyltrimethoxysilane and 1g of organozinc catalysts were added to the reaction vessel for reaction. The reaction time was 8 hours,...

Abstract

The invention discloses a recyclable fever cooling patch. Polyglycol 6000 and polyglycol 10000 serve as soft segments, energy is stored through phase changes of the soft segments, and isocyanate, a chain extender and small-molecule polyol serve as hard segments, wherein the isocyanate is selected from a mixture of methylenediphenyl diisocyanate and 3-isocyanate group propyl group triethoxy silane;the chain extender is selected from N-methyl diethanolamine and 3-amino-1,2,4-triazole-5-carboxylic acid, wherein the N-methyl diethanolamine serves as a first chain extender body to react, and the 3-amino-1,2,4-triazole-5-carboxylic acid serves as a second chain extender body to react; styrene and N-aminoethyl-3-aminopropyltriethoxysilane are further added between two times of chain extension; and the small-molecule polyol is selected from three substances of 1,4-butanediol, 2,2-dimethyl-1,3-propylene glycol and 1,2,3-hexanetriol. The prepared fever cooling patch can be used for multiple times not only once, the resource utilization rate is increased, and the economic cost is lowered.

Description

technical field [0001] The invention relates to a medical product, more specifically to a recyclable antipyretic patch. Background technique [0002] Fever, especially fever in children is a common and frequently-occurring disease. If it is not treated in time, it will affect the health of children. The existing antipyretics for cooling have large side effects and are mostly oral medicines, which are not used by children. And before the cause of the fever is found, antipyretic drugs cannot be used blindly for treatment, as this will easily cover up the condition and affect further treatment. [0003] The antipyretic patch is a new technology developed in recent years for emergency cooling of high fever. The existing antipyretic patch consists of three layers, which are anti-adhesive layer, gel layer and protective layer. The principle is that the gel layer The polymer gel in the formula locks liquid water, which absorbs the heat on the forehead surface and converts it into ...
