The invention discloses a room temperature/low temperature vulcanized chloroprene rubber sizing material, which relates to rubber. The rubber sizing material is obtained by mixing and processing the following components in parts by mass: 100-30 parts of chloroprene rubber, 0-70 parts of natural rubber, 0-1 part of sulfur S, 4-7 parts of T-ZnO crystal whiskers, 1-6 parts of magnesium oxide, 0-3 parts of TM808, 0.5-1.5 parts of accelerating agent TMTD (Tetramethylthiuram Disulfide), 20-50 parts of tert-butyl phenol formaldehyde resin, 1-6 parts of stearic acid and the balance of compound anti-ageing system consisting of 4010Na and D, carbon black and a paraffin aid, wherein the sulfur S, the T-ZnO crystal whiskers and the magnesium oxide jointly serve as a dual vulcanizing agent, and the TM808 and the accelerating agent TMTD jointly serve as a compound accelerating agent. The chloroprene rubber sizing material obtained by the invention can be vulcanized at room temperature/low temperature, has high scorching property, high adhesion on a framework material and the advantages of ageing resistance, high physical and mechanical performance, high ozone resistance, high oxidation resistance, combustion resistance and the like, and is particularly suitable for the production of large-sized rubber products or the construction of field vulcanization.
