The invention has the technical effects that: (1) according to the mask, the elastic band layer is arranged on the inner side face of the mask body, when the mask is used, a user only needs to tear off the two U-shaped bodies in the elastic band layer along the tearing line to form 2 elastic bands, and specifically, the bottoms of the pair of U-shaped bodies are respectively sleeved on the two ears of the user, so that the mask can be worn. Because the elastic belt layer and the mask body are designed in a laminated mode, the continuous elastic belt layer and the continuous mask body can be synchronously and quickly conveyed up and down on a production line during production, continuous and quick production of the production line is facilitated, the problem that the elastic belt needs to be fixed one by one in the prior art is solved, the production efficiency can be greatly improved, the production time is shortened, the production speed of one production line can reach 800 pieces/minute at the fastest speed, and the well-blowout type requirement of public health safety events to the mask due to emergencies can be greatly relieved. (2) The mask can be used after being torn along the tearing line, so that a user can conveniently judge whether the mask is used or not, and the safety risk possibly brought by the crossed use of the mask is avoided. (3) In the disposable protective mask, the high-molecular water-absorbent resin particles (SAP) in the medical mask are dispersed and distributed, and can not be agglomerated after absorbing water, so that each SAP particle is suitable for fully absorbing water, the water absorption utilization rate of the SAP can be greatly improved, the mask is ensured to be in a dry state all the time, bacteria are prevented from breeding, and the service life of the mask is prolonged; the SAP dispersion distribution does not affect the breathing function of the medical mask. (4) When the disposable protective mask is taken down, the opening at the bottom is lifted upwards to the outward flanging, so that the outer side surface of the medical mask faces inwards, and bacteria on the outer side surface of the medical mask are prevented from leaking outwards.
