Abstract

The invention provides a high-performance stamp gum cleaning agent, which comprises the following components by weight: turpentine 20-40%, n-heptane 10%, absolute ethanol 10%, naphtha 15-60%, butyl acetate Acid cellulose solution 0~5%, mixed acid dimethyl ester 0~50%. The high-performance cleaning agent for stamp gum of the present invention adopts cellulose acetate butyrate as a film-forming substance, naphtha as a main solvent, absolute ethanol, n-heptane, and turpentine as an auxiliary solvent. The solvent with naphtha as the main component will quickly penetrate into the gap between the stamp and the envelope, and reach the glue film to separate the glue film from the back of the stamp. At this time, the glue film can be peeled off quickly; at the same time, the film-forming substance can also keep the stamp. Glossiness and saturation of pattern colors are not affected. The preparation method of the high-performance stamp back glue cleaning agent of the invention is simple and convenient to use.
