Smoke filter liquid for cigarette filters as well as preparation method and application of smoke filter liquid

Abstract

The invention provides smoke filter liquid for cigarette filters as well as a preparation method and application of the smoke filter liquid. The smoke filter liquid is polylactic acid nanometer suspension liquid prepared from an organic phase and a water phase by virtue of a self-emulsifying solvent evaporation method, wherein the organic phase is prepared by dissolving polylactic acid powder into a mixed solvent of acetone and ethanol, the water phase is prepared by dissolving a surfactant into ultrapure water, the particle diameters of polylactic acid nano-particles are 110nm-210nm, and the surface potential is (-65mV)-(+80mV); the mass ratio of the organic phase and the water phase is (1 to 5)-(2 to 5), and the surfactant is one of poloxamer188, lauryl sodium sulfate, cetyl trimethyl ammonium bromide, taurine and sodium cholate. According to the smoke filter liquid, the problems that tar in smoke cannot be well filtered by virtue of existing cigarette filters, and a smoking device for shredded tobacco for water pipes is complex are simultaneously solved, furthermore, the whole preparation process is simple and convenient, and the taste of cigarettes is not influenced.

Description

technical field [0001] The invention belongs to the field of cigarette smoke filtration, and in particular relates to a smoke filtrate used in cigarette filters and a preparation method and application thereof. Background technique [0002] The main components of cigarettes are tar (polycyclic aromatic hydrocarbons) and nicotine (nicotine), and wherein tar is a strong carcinogen, which is particularly harmful to the human body. Nicotine also has very strong toxicity and will also endanger the health of the human body. Because the tar in cigarette smoke becomes gaseous at high temperature, the filter tip on the common cigarette has very limited filtering effect on the tar in cigarette smoke. [0003] Hookah originated in India 800 years ago. It consists of coconut shells and diabolo pipes. It is mainly used to smoke old-fashioned black tobacco. Later, it gradually spread to the Arab world (it has a history of 500 years), was carried forward by the Arabs, and became a common ...

AI Technical Summary

Problems solved by technology

However, hookah requires a set of specific hookah smoking device, which is not easy to carry, and the operation is relatively complicated, which is not conducive to popularization and use.
