AI Technical Summary

Problems solved by technology

However, after adding these flame retardants to cigarette paper, there are two problems. One is that when the cigarette is held in the hand in a smoldering state, it is easy to extinguish and needs to be re-lit
Second, the smoking quality of cigarettes has declined to varying degrees.

Abstract

The invention discloses temperature-sensitive low ignition propensity cigarette paper. The outer surface of the temperature-sensitive low ignition propensity cigarette paper is coated with a temperature-sensitive flame-retardant belt layer; the temperature-sensitive flame-retardant belt layer comprises a plurality of temperature-sensitive flame-retardant belts; and each of the temperature-sensitive flame-retardant belts comprises a temperature-sensitive composite material and an essence. According to the preparation method, the temperature-sensitive flame-retardant belts containing the temperature-sensitive composite material and the essence are arranged on the temperature-sensitive low ignition propensity cigarette paper, and the temperature-sensitive composite material is at solid state at room temperature; when cigarettes made of the temperature-sensitive low ignition propensity cigarette paper is burned to the temperature-sensitive flame-retardant belts, the temperature-sensitive composite material is triggered to change from solid state into liquid state with increasing of the temperature, so that quenching of the cigarettes is realized, and cigarette ignition propensity is lowered. The cigarettes are provided with the temperature-sensitive flame-retardant belts, so that quenching of the cigarettes are not caused when the cigarettes are held by hands, and when the cigarettes are placed on combustibles, quenching is caused. In addition, design of the essence formula is capable of avoiding negative effects on cigarette fragrant flavour, and solving universal problems of existing low ignition propensity cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarette paper, in particular to a cigarette paper with temperature sensitivity and low ignition tendency and a preparation method thereof. Background technique [0002] Through the analysis of fire statistics in Canada from 1955 to 1999, tobacco products are the main items that cause residential fire-related losses every year. According to the Canadian Federation of Fire Chiefs, tobacco products cause at least 14,030 fires each year, resulting in 365 deaths, 1,615 injuries, and $200 million in property damage. Victims are often the most vulnerable in society such as children, the elderly and the economically poor. In 2004, Canada enacted the Cigarette Flaming Act. According to statistics from the American Burn Association and the U.S. federal government, about 25% of fires in the United States are caused by smoking. About 900 people die each year, more than 250 people are injured, and the economic lo...
