Antibacterial polymer liquid storage eyeliner and material preparation method thereof

The invention relates to an antibacterial polymer liquid storage eyeliner and a material preparation method thereof, and is designed for solving the technical problems that the existing similar products are poor in sealing performance, refills are lack of protection structures, and corresponding materials are poor in preparation and production. A spring and an inner cover are arranged at the innerbottom of an outer cover of the eyeliner, and a brush holder of a brush abuts against an inner step ring of the inner diameter of a pen hole in a pen nozzle. The eyeliner is characterized in that a diversion core is arranged on a central shaft of a diversion seat in the eyeliner mouth, an upper catching groove and a lower catching groove of the diversion seat are respectively buckled with an inner transition ring and an inner conical rib on the inner wall of the eyeliner mouth, and when an eyeliner buckling rib of the eyeliner tube is buckled with an outer buckling rib of the eyeliner mouth,an eyeliner opening of the eyeliner tube abuts against an outer convex rib of the eyeliner mouth. An outer cover is arranged on the outer diameter of one end of the brush of the eyeliner tube and slides up and down through a pin on the outer diameter of the eyeliner tube and a sliding groove in the inner wall of the outer cover. An isosceles triangle guide groove is formed in one side of the outerdiameter of the pen tube, one end of an elastic hook between the eyeliner tube and the outer cover is fixed to the inner wall of the outer cover, and the other end of the elastic hook is fixed to theguide groove, and the eyeliner mouth is an antibacterial polymer pen mouth.
