The invention belongs to the technical field of harm and tar reduction of cigarettes, and particularly relates to a resin material for reducing hydrocyanic acid release quantity in main stream smoke of cigarettes selectively as well as a preparation method thereof. The material is an anion exchange resin material or a chelating resin material loaded with metal ions. The preparation method comprises the following steps: spraying absolute ethyl alcohol for anion exchange resin which is subjected to GB/T5476-1996 standard treatment, and drying; spraying absolute ethyl alcohol for chelating anion exchange resin which is subjected to GB/T5476-1996 standard treatment, drying, immersing into a water solution containing transition metallic ions, and cleaning. According to the invention, the types of filter additive materials for reducing hydrocyanic acid in the cigarette main stream smoke increase; the using fields of ion exchange resin and chelating resin are widened; the treatment method of the resin material is simple, and is convenient to operate; raw materials are obtained easily, and are low in cost; moreover, the resin material is high in hydrocyanic acid preferential adsorption, so that the resin material for reducing hydrocyanic acid release quantity in main stream smoke of cigarettes selectively as well as a preparation method thereof have favorable application value.
