| titleOfInvention | Preparation method of hydrogel patch matrix |
| abstract | The invention relates to a preparation method of patch matrix, in particular to a preparation method of hydrogel patch matrix, and belongs to the technical field of medicine. The preparation method takes methacryloyl polyvinyl alcohol as tackifier, adopts a hydrogen bonds network structure formed among hydroxyl on the molecular chain of the methacryloyl polyvinyl alcohol, hydroxyl of crylic acid-sodium acrylate copolymer of matrix and hydroxyl on polyvinylpyrrolidone molecule to ensure that hydrogel patch coated is immediately solidified through an ultra-violet polymerization method, improvesthe forming stability of the hydrogel patch, avoids phenomena of flowing and transformation of the coated hydrogel patch during immediate packaging process, is not required to be packaged after hoursof standing, and greatly improves the preparation efficiency of the hydrogel patch. Meanwhile, the adhesion property of the patch matrix reaches more than an initial stick force 18# steel ball and the adhesion effect of more than 10 times of repeated adhesion. |
