The invention relates to a shock-absorption anticorrosion gas-phase rustproof rod and a manufacturing method. The shock-absorption anticorrosion gas-phase rustproof rod is characterized in that an inner core is a piece of gas-phase rustproof paper or a piece of gas-phase rustproof nonwoven fabric with the cross section being in continuous M-shaped gear ring shape, two ends of the M-shaped sectional material in the length direction are in but joint to form a cylinder to be installed into a shell; the outer walls of two ends of the shell and the inner wall of an end cover are respectively provided with a convex ring so as to realize the fast insertion; a resilient protection cover wraps the end cover of the shell; a connecting piece on the end cover is serially connected with the adjacent gas-phase rustproof rod. The production method of the rod inner core comprises the following steps: determining the length of the inner core according to the specification length requirement of a rustproof rod product, adopting the amplitude of the gas-phase rustproof paper as the length, and calculating the height of a piece of M-shaped fold paper according to the diameter of a finished product rustproof rod; uniformly folding the long edge of the paper, relatively binding two ends of the M-shaped fold paper in the length direction at the compression state to form the cylinder conforming to the diameter of the finished product rustproof rod, wherein the circular center gap is minimal. By adopting the invention, the surface area, contacted with the peripheral air, of the gas-phase rustproof paper is increased, the contained corrosion inhibitor can form the effective concentration within a short time, and the problems that the corrosion inhibitor cannot take effectiveness in time in high ambient humidity and temperature due to the long volatilization time of the corrosion inhibitor caused by the barrier of the wrapping material can be solved.
