NOVELTY - The utility model relates to the technical field of isolation mask, specifically to an isolation mask using graphene modified polyurethane foam, comprising a mask main body, the middle part of the mask main body is provided with a circle of rubber ring, the rubber ring end is integrally connected with four rubber extending belt; four respectively belts fixedly connected with four rubber belts respectively fixedly connected to the four rubber belt fixing rubber blocks; four rubber belt fixing rubber blocks are fixedly connected on the locking device. The utility model cancels the common respiratory part, directly combines it and the mask lens into a whole, increases the field of view, convenient for the wearing staff to work; combining the bandage fixed at the back of the mask; the rubber belt is connected in the locking device; changing the material of the mask lens into graphene synthetic high polyester material, increasing the intensity of the mask, adding polyurethane foam filter in the respiratory tube, increasing the medical characteristic and dust-proof effect.
