Problems solved by technology

The hydrogel in the antipyretic patch plays a vital role in the antipyretic effect of the antipyretic patch; the existing antipyretic hydrogels on the market tend to fall off on the skin surface at room temperature or high temperature, and the antipyretic patch Not fully volatilized, resulting in waste

preparation example Construction

[0012] The invention provides a cooling hydrogel and a preparation method thereof, comprising alcohol, mint lactate, skin penetrating agent, sodium polyacrylate, glycerin, purified water, acrylamide, crospovidone, light curing agent, pigment , Borneol and polybutylene adipamide. The raw materials were mixed to obtain a mixture, and the mixture was placed under the condition of ultraviolet light for 180 s to cause the mixture to undergo a curing reaction to prepare the cooling hydrogel.

[0013] Wherein, the mixture can be divided into two stages from the beginning of solidification to completion: the first stage is from the beginning of timing to the time of curing to 150s. This stage is a stage in which the photoreaction proceeds rapidly, and the C-C bond breaks to generate a large amount of activation energy. A large amount of evaporation is 20%-30%; the second stage is the stage in which the photoreaction continues and proceeds stably, and the evaporated water in this stage...

Embodiment 1

[0015] A kind of cooling gel, comprising the following raw materials in mass percentage: 0.5% alcohol, 0.4% mint lactic acid ester, 0.4% skin penetration agent, 0.4% sodium polyacrylate, 40.45% glycerin, 35.2% Purified water, 17.25% acrylamide, 3.5% crospovidone, 0.5% photocuring agent, 0.2% pigment, 0.6% borneol and 0.6% polybutylene adipamide.

Embodiment 2

[0017] A kind of antithermogel, comprising the following raw materials in mass percentage: 0.5% alcohol, 0.4% mint lactic acid ester, 0.4% skin penetration agent, 0.4% sodium polyacrylate, 35.7% glycerin, 39.95% Purified water, 17.25% acrylamide, 3.5% crospovidone, 0.5% photocuring agent, 0.2% pigment, 0.6% borneol and 0.6% polybutylene adipamide.

Abstract

The invention discloses a febrifuge hydrogel. The febrifuge hydrogel includes an additive and a solvent, wherein the mass proportion of the additive is 56.3%-64.3%, and the mass proportion of the solvent is 35.7%-43.7%; the solvent comprises alcohol and purified water; and the additive comprises menthyl lactate, a percutaneous penetration agent, sodium polyacrylate, glycerol, acrylamide, crosslinked povidone, a light curing agent, a pigment, borneol and tetramethylene adipamide. The invention further discloses a preparation method of the febrifuge hydrogel. The febrifuge hydrogel is applied tofebrifuge patches and has a good energy conversion function, through vaporization of a large amount of own moisture and volatilization of the food-grade cooling agent, human-body heat is rapidly taken away, and thus tender brain cells of children are protected. The febrifuge hydrogel contains the percutaneous absorption accelerant, so that effective components in the febrifuge hydrogel penetratethrough skin and then rapidly enter blood circulation, and comprehensive and durable effects are achieved.

Description

technical field [0001] The invention relates to the field of medical medicine, in particular to an antithermogel and a preparation method thereof. Background technique [0002] The antipyretic patch has antipyretic and cooling effects, and can relieve fever, headache, toothache, sun exposure, pain and heat symptoms caused by muscle sprains. The hydrogel in the antipyretic patch plays a vital role in the antipyretic effect of the antipyretic patch; the existing antipyretic hydrogels on the market tend to fall off on the skin surface at room temperature or high temperature, and the antipyretic patch Can not be completely volatilized, resulting in waste. Therefore, it is necessary to improve the prior art. Contents of the invention [0003] The object of the present invention is to provide a cooling hydrogel and its preparation method, which can not only solve the problems raised in the above-mentioned background technology, but also greatly improve the production efficienc...
