Problems solved by technology

However, since the high temperature (50-70°C) is used in this patent to initiate high internal phase emulsion polymerization to prepare polyglycidyl methacrylate interconnected porous materials, the high polymerization temperature will cause partial ring opening of the epoxy group, which will affect The reduction effect of the material on phenol in the flue gas; the low polymerization temperature can inhibit the ring-opening of the epoxy group, so it is possible to develop a high-epoxy polyglycidyl methacrylate interconnection at a lower polymerization temperature Porous materials, and applying them in cigarette filters, and then improving the effect of reducing phenol in cigarette smoke are just the research purpose of the present invention, and there is no research report on this aspect in the current open literature

Abstract

The invention provides application of high-content epoxy group polyethylene glycidyl methacrylate interconnected porous materials in cigarettes. The application is characterized in that high internal phase emulsion polymerization of the glycidyl methacrylate (GMA) is triggered through radiation to obtain the polyethylene glycidyl methacrylate porous materials (Poly GMA) with high content of epoxy group. Compared with reported Poly GMA materials, the polyethylene glycidyl methacrylate interconnected porous materials (Poly GMA) has higher content of epoxy group, and can more effectively absorb harmful substance phenol in smoke gas. 5-20mg of the Poly GMA materials are added in each cigarette filter rod so that the releasing amount of phenol in main stream smoke gas in the cigarettes can be selectively reduced by above 35%, and negative effects on the smoking quality of the cigarettes are not caused. Therefore, the purpose that the releasing amount of the phenol in the smoke gas in the cigarettes is selectively reduced is achieved.

Description

technical field [0001] The invention relates to the application of porous adsorption materials in cigarettes, in particular to the application of a polyglycidyl methacrylate interconnected porous material with high epoxy group content to selectively reduce the phenol release 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....
