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 application of the invention involved in porous adsorbing materials in cigarettes is specifically a high -ring -based polymel acrylic hydrocytide interoperability in cigarettes in the application of cigarettes on cigarettes.Applying this material to a cigarette filter can effectively reduce the amount of phenol release in the mainstream flue gas, and at the same time, it does not have a negative impact on the quality of cigarette absorption. Background technique [0002] The volatile phenolic compounds in cigarette gas are mainly produced during the combustion of cigarettes. Phenol is one of the most important harmful components that affect the mainstream smoke gas harmfulness of cigarettes.Therefore, reducing the phenol content in cigarette gas is of great significance to reduce the harm of cigarettes. [0003] There are many related research at home and abroad for how to reduce phenols in cigarette gas.Wang Hongwei et al. (Anhui Agricultural Science, ...
