Preparation method of network interpenetrating mask base material

The invention provides a preparation method of a network interpenetrating mask base material. A network interpenetrating mask is prepared in a solution blending mode. The material is prepared with sodium alginate and gelatin as raw materials, and catechin and calcium chloride as cross-linking agents. Material sources are wide, the price is low, the production efficiency is high, the application range is wide, the obtained mask base material is better in mechanical property, and the water absorption and water-retaining property are greatly improved. 种网络互穿面膜基材的制备方法，是通过溶液共混方式制备互穿网络膜。采用海藻酸钠和明胶作为原料，选用儿茶素和氯化钙作为交联剂制得。本发明材料来源广泛，价格低廉，生产效率高，应用性广，得到面膜基材的力学性能更佳，吸水保水性大大提高。
