Embodiment 1

[0023] Prepare the oil phase first, the composition is 6ml styrene, 2ml divinylbenzene, 5ml toluene, 0.2g benzoyl peroxide BPO, and then configure the water phase, the composition is 80 ml water, 0.5g sodium chloride and 2 g polyethylene alcohol. 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 obtained spherical product was extracted with ethanol for 24 hours to obtain the macroporous adsorption resin 1.

[0024] It is used as a composite filter additive with an additive amount of 15 mg / cig. Taking the cigarette without adding any filter modified material as a control sample, the cigarette smoking test is carried out on a smoking machine according to the standard smoking conditions, and according to 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.

Abstract

The invention relates to application of macroporous adsorption resin to cigarettes, which is characterized in that adding the macroporous adsorption resin to a filter of each cigarette can selectively reduce phenol release in mainstream smoke of the cigarette by more than 25%, 10-30mg of the macroporous adsorption resin is added per filter, and the macroporous adsorption resin obtained by suspension polymerization comprises divinyl benzene, styrene, pore-forming agent, initiator, water, inorganic salt and dispersant. The macroporous adsorption resin is capable of effectively adsorbing harmful phenol in smoke while tar release is substantially unchanged or slightly lowered, and has no adverse effect on smoking quality of the cigarettes, and accordingly the phenol release in the smoke of the cigarettes is selectively reduced.

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 macroporous adsorption resin which selectively reduces the amount of phenol released 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. [0003] Background technique [0004] 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 signif...
