Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a medical conductive adhesive and a preparation method thereof. Background technique [0002] Medical conductive adhesives can be divided into conductive pressure-sensitive adhesives and conductive hydrogels. Their normal production process is to prepare the glue according to the formula and process requirements and then light-cure it to make a film. However, some special requirements require that the prepared glue It has a greater viscosity and a longer lifespan so that it can still be used after a period of time. However, at present, many medical conductive adhesives are not thick enough, and they will lose water and shrink when left in the air for a period of time, which will affect the performance of the product. Therefore, it is necessary to develop a kind of medical conductive adhesive with higher viscosity and long life. Contents of the invention [0003] Aim...
