Filter tip additive material capable of improving sensory characteristics of smoke and application thereof

Abstract

The invention discloses a filter tip additive material capable of improving the sensory characteristics of smoke and the application thereof. The filter tip additive material is characterized by being prepared by carrying a mixed solution of propylene glycol and sorbitol on a carrier which is a mixture of porous SiO2 and Al2O3 particles. A two-element or multi-element combined filter tip can be manufactured by adding the prepared filter tip additive material into a cigarette filter stick. The filter tip additive material prepared through the method contains a low-molecular hydrophilic moisture-retaining agent, moisture can be effectively retained for a long time and can be rapidly released when a cigarette is smoked, the moisture content in the smoke of the cigarette is increased, and the sensory quality of the cigarette is improved. Meanwhile, by means of the method, the content of harmful ingredients such as tar and total particulate matter in the smoke can be effectively reduced. In addition, the filter tip additive material is nontoxic, harmless and low in cost and has broad industrial prospects, and the preparation process is simple and easy to implement.

Description

technical field [0001] The invention relates to a cigarette filter additive material, in particular to a filter additive for improving the sensory characteristics of cigarette smoke. The additive can increase the moisture content in the cigarette smoke and improve the sensory quality of the cigarette. At the same time, the content of harmful components such as tar and total particulate matter in the flue gas can be effectively reduced, and the materials are easy to obtain and the preparation process is simple. Background technique [0002] The moisture content in cigarette smoke is a very important factor affecting the sensory quality of cigarettes. The low moisture content in the smoke will cause the smoke to dry out, increase the stimulation, reduce the comfort, and significantly reduce the sensory quality of the cigarette. At present, more and more low-tar cigarettes, as well as more and more harm reduction technologies, mostly adopt a large amount of ventilation techno...

Problems solved by technology

However, the carrier materials used are often obtained by modifying plant materials, which will have peculiar smell and affect the sensory quality of the product. In addition, the cost of using ion exchange resins and other materials is relatively high.
