Smoke temperature-controllable and low temperature-incombustible cigarette filter rod and preparation method thereof

Abstract

The invention relates to a smoke temperature-controllable and low temperature-incombustible cigarette filter rod and a preparation method thereof. Polylactic acid particles with a certain particle size are uniformly embedded in filter tows for cigarettes at a certain proportion to prepare the low temperature-incombustible cigarette filter rod for solving universal problems that control of the smoke temperature is not good enough, a smoke channel is easy to be blocked, and smoke suction taste is not good enough in existing common products. The polylactic acid material, glycerol triacetate and other environment-friendly modifying additives introduced in the invention have advantages of good biocompatibility, biodegradability, safety and environmental protection; the materials not only are non-toxic to a human body, but also are in conformity with a principle of green economy; and the filter rod prepared by the method can be widely used in low temperature-incombustible cigarettes.

Description

technical field [0001] The invention relates to the technical fields of adsorption filter materials and tobacco, in particular to a cigarette filter rod with controllable smoke temperature and low-temperature non-combustibility and a preparation method thereof. Background technique [0002] There are usually dozens of carcinogens in the smoke produced by the combustion of traditional cigarette products. Relevant studies have shown that the formation of various chemical substances in smoke is closely related to the level of cigarette burning temperature, and the hazard index of cigarettes increases with the increase of cigarette burning temperature. In addition, the smoke generated by combustion permeates the air to form second-hand smoke. Heat-not-burn cigarettes are a new type of cigarette products. Unlike traditional cigarettes, low-temperature cigarettes designed with heat-not-burn in mind can heat the tobacco leaves just enough to release the flavor without igniting th...

Problems solved by technology

However, this polylactic acid material will melt when it comes into contact with the initial, excessively high-temperature flue gas, causing the flue gas channel to be blocked, so it must be set at a sufficient distance from the heating element. The reason for designing a hollow filter section between the heating elements

Even so, after smoking is finished, the polylactic acid film at the front is still partially melted, and some smoke channels are blocked

In addition, the research results also show that the smoke temperature of Philip Morris Tobacco International's IQOS products is not ideal, and there is still a slight burning sensation
