The invention relates to an antibacterial and pressure-resistant single-tube lipstick pen and its material preparation method, aiming to solve the defects of poor rotating hand feeling, insufficient structural stability and defective raw materials of existing similar products. The fork base is sleeved on one end of the pen barrel to form a pen cavity, with a rotating bead installed inside. The inner cavity of the pen barrel is a cylindrical structure. A threaded groove is arranged at the bead insertion end of the fork base, and the external thread at one end of the bead is screwed into the fork base along the threaded groove. Raised annular ribs are arranged on the outer diameter of the threaded groove. Vertically and equidistantly distributed positioning ribs are arranged on the outer wall of the other end of the bead, and matching guide grooves are formed on the inner wall of the pen barrel. The outer diameter at the positioning ribs is smaller than that of the threaded section, so that the bead is limited at the opening of the fork base. A partition with through holes is arranged between the upper and lower inner cavities of the bead, and equidistant convex ribs are arranged in the upper cavity. Key components are made of antibacterial and pressure-resistant materials.
