Embodiment 1

[0021] First configure the oil phase, the composition is 5ml vinyl acetate, 5ml divinylbenzene, 5ml 200# gasoline, 0.2g benzoyl peroxide BPO, and then configure the water phase, the composition is 80 ml water, 0.5g sodium chloride and 2 g polyvinyl alcohol. Under stirring, the water phase was added into the oil phase, then the temperature was raised to 70° C., and the reaction was carried out for 12 hours. The resulting pellets were extracted with ethanol for 24 hours to obtain polyvinyl acetate adsorption resin 1.

[0022] Use it as a composite filter additive, with an additive amount of 15mg / cig. Taking the cigarette without any filter modified material as a control sample, carry out a cigarette smoking test on a smoking machine according to standard smoking conditions, and follow the standard YC / T255-2008 for the detection of phenol release. Three parallel samples were taken for each sample, and the results are shown in Table 1.

Embodiment 2

[0028] First configure the oil phase, the composition is 5ml vinyl acetate, 5ml divinylbenzene, 10ml butyl acetate, 0.2g azobisisobutyronitrile, and then configure the water phase, the composition is 80 ml water, 0.5g calcium chloride and 2 g Gelatin. Under stirring, the water phase was added into the oil phase, then the temperature was raised to 80° C., and the reaction was carried out for 12 hours. The resulting pellets were extracted with ethanol for 24 hours to obtain polyvinyl acetate adsorption resin 2.

[0029] Use it as a composite filter additive, with an additive amount of 15mg / cig. Taking the cigarette without any filter modified material as a control sample, carry out a cigarette smoking test on a smoking machine according to standard smoking conditions, and follow the standard YC / T255-2008 for the detection of phenol release. Each sample has three parallel samples, and the results are shown in Table 2.

Abstract

The invention relates to application of polyvinyl acetate adsorption resin on cigarettes and is characterized in that the polyvinyl acetate adsorption resin is added to cigarette filters, the release amount of phenol in mainstream smoke in the cigarettes can be selectively reduced by over 25%, and the adding amount of the polyvinyl acetate adsorption resin in each filter is 10-30mg. The polyvinylacetate adsorption resin is prepared by suspension polymerization and is composed of raw materials: divinyl benzene, vinyl acetate, a pore-foaming agent, an initiating agent, water, inorganic salt and a dispersing agent. The polyvinyl acetate adsorption resin material can effectively adsorb the harmful substance phenol in the smoke, the release amount of tar is substantially unchanged or slightlyreduced, negative effects on smoking quality of the cigarettes are avoided simultaneously, and accordingly the aim of selectively reducing the release amount of phenol in the cigarette smoke is achieved.

Description

[0001] technical field [0002] The invention belongs to the field of additive materials for reducing harm of cigarettes, and in particular relates to the application of a polyvinyl acetate adsorption resin for selectively reducing the release of phenol in mainstream smoke of cigarettes in reducing harm of cigarettes. Applying the material to cigarette filter rods can effectively reduce the amount of phenol released in mainstream smoke without negatively affecting the smoking quality of cigarettes. Background technique [0003] Phenol is one of the main harmful components of cigarette mainstream smoke. The volatile phenolic compounds in cigarette smoke are mainly produced during the burning process of cigarettes. According to the relationship between biological activity, phenol is one of the most important harmful components affecting the harmfulness of mainstream cigarette smoke. Therefore, reducing the phenol content in cigarette smoke is of great significance for reducing...
