Preparation method of antistatic polyurethane sponge material and application of modifier

The invention discloses a preparation method of an antistatic polyurethane sponge material and application of a modifier. The preparation method of the antistatic polyurethane sponge material comprises the following steps: dipping polyurethane sponge in an antistatic modifier solution, so that the polyurethane sponge adsorbs the antistatic modifier solution; adding water until the water submerges the polyurethane sponge, and stirring in a water bath at 90-100 DEG C for 1-8 hours to generate a reduction reaction; and drying the polyurethane sponge after the reaction to obtain the antistatic polyurethane sponge material. According to the method disclosed by the invention, the polyurethane sponge is modified, and the modifier can be firmly combined with the polyurethane sponge and is not easy to desorb after a reduction reaction. The modifier adopted by the invention is green and environment-friendly, easy to prepare, convenient to use and good in modification effect, and can modify the originally insulated poly
