Preparation method of antistatic hydrogel

The invention discloses a preparation method of antistatic hydrogel, belongs to the field of preparation of hydrogel, and provides the antistatic hydrogel which is prepared through the following steps: adding assistants such as an antistatic agent into the raw materials, namely, desugared sodium lignin sulfonate, hemicellulose, gelatin and water, so as to obtain sodium lignin sulfonate gel; adding sodium peroxide for reaction, so as to form micropores in the surface of the gel; adding conductive materials such as carbon black and carbon fiber into the micropores, so as to finally obtain the antistatic hydrogel. The preparation method provided by the invention is easy to operate, the technology is stable, and the produced gel is good in adhesive property, antistatic effect and storage stability.
