Water-based fireproof coating plate spraying experiment device

The utility model discloses a water-based fireproof coating plate spraying experiment device, which belongs to the technical field of spraying equipment and comprises a processing table, a spraying mechanism and a shielding mechanism, the spraying mechanism comprises four mounting plates, each mounting plate is fixedly connected to the top of the processing table, and the shielding mechanism comprises four movable rods. Each movable rod is movably embedded in the mounting frame, a plurality of spray heads at the bottom of the liquid storage box spray a plate at the top of the processing table, and a threaded rod on a mounting plate rotates to drive a threaded block to move and drive the mounting frame to move, so that the liquid storage box and the spray heads are driven to move, and the use convenience of the spraying mechanism is facilitated; the spraying range of the spraying head can be controlled through a shielding plate in the shielding mechanism, the situation that the spraying head is sprayed to the
