Abstract

The invention discloses a preparation method and application of a poly-glycidyl methacrylate interosculated porous material. The preparation method is characterized in that the poly-glycidyl methacrylate interosculated porous material (PolyGMA) with an epoxy functional group is obtained through high internal phase emulsion polymerization of glycidyl methacrylate (GMA), and the material can adsorb a harmful substance namely phenol in smoke gases. The material can selectively reduce over 25 percent of the released amount of the phenol in cigarette mainstream smoke gas by adding 10 to 30 mg of the material into each cigarette filter stick, but the released amount of tar is basically not changed or is reduced slightly; and simultaneously, the material does not generate negative effect on the smoking quality of cigarettes, thereby fulfilling the aim of selectively reducing the released amount of the phenol in the cigarette smoke gas.

Description

technical field [0001] The invention relates to a preparation method and application of a polyglycidyl methacrylate interconnected porous material for selectively reducing the release of phenol in mainstream smoke 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 [0002] Volatile phenolic compounds in cigarette smoke are mainly produced during the burning process of cigarettes, and phenol is one of the most important harmful components affecting the harmfulness of mainstream smoke of cigarettes. Therefore, reducing the phenol content in cigarette smoke is of great significance for reducing the harm of cigarettes. [0003] Many related studies have been carried out at home and abroad on how to reduce phenol in cigarette smoke. Wang Hongwei et al. (Anhui Agricultural Science, 2009 (10) 4371-4372.) studied c...
