Special hydrophilic macromolecular gel material for fever cooling patch

The invention discloses a special hydrophilic macromolecular gel material for a fever cooling patch, which relates to the technical field of biological medicine materials. A preparation method comprises the following steps: (1) preprocessing feathers; (2) extracting high-purity feather keratins; (3) modifying the feather keratins; (4) preparing a hydrophilic auxiliary material; and (5) preparing a gel material. The macromolecular gel material prepared by the invention is hydrophilic but not soluble in water, so that a great amount of water is maintained without being dissolved, and the significant cooling and fever lowering effect can be realized; and moreover, the action time is long, and one-time application time can reach 12h. 本发明公开了种退热贴专用亲水性高分子凝胶材料，涉及生物医药材料技术领域，其制备方法包括如下步骤：(1)羽毛预处理，(2)高纯度羽毛角蛋白的提取，(3)羽毛角蛋白的改性，(4)亲水性辅料的制备，(5)凝胶材料的制备。本发明使所制高分子凝胶材料亲水但不溶于水，保持大量水分而不溶解，从而发挥显著的降温退热效果，并且作用时间长，次使用时间可达12h。
