Heat-conducting flame-retardant cigarette paper for cigarettes, and preparation method and application thereof

Abstract

The invention discloses a heat-conducting flame-retardant cigarette paper for cigarettes, and a preparation method and an application thereof. The preparation method of the heat-conducting flame-retardant cigarette paper comprises the following steps: (1) preparing a heat-conducting flame-retardant slurry, wherein the heat-conducting flame-retardant slurry comprises a heat conducting material anda phosphorus flame retardant; the heat conducting material is one or more of an aluminum nitride powder, an aluminum oxide powder, a boron nitride powder and a silicon carbide powder; and the phosphorus flame retardant is one or more of soluble dihydric phosphate and ammonium polyphosphate; and (2) applying the heat-conducting flame-retardant slurry to the surface of a cigarette paper, or coatingthe surface of a papermaking base paper with the heat-conducting flame-retardant slurry to obtain the heat-conducting flame-retardant cigarette paper. When the heat-conducting flame-retardant cigarette paper is used for heating a cigarette, combustion of the cigarette paper can be prevented, the heat transfer efficiency and the smoke release amount of the cigarette paper are obviously improved, and the appearance quality and the internal quality of the low-temperature heating type cigarette are synchronously improved.

Description

technical field [0001] The invention relates to a heat-conducting and flame-retardant cigarette paper for cigarettes, a preparation method and application thereof, and belongs to the technical field of cigarette paper processing. Background technique [0002] Smoking is harmful to health, and the public is increasingly concerned about smoking and health issues. The pace of international tobacco control campaigns is accelerating, and restrictions on smoking in public places are becoming more and more stringent. In order to adapt to the tobacco control campaign and reduce the health hazards of tobacco, tobacco companies around the world, such as Philip Morris, Anglo-American, etc., are actively researching and developing various new tobacco products. Tobacco consumers welcome. At present, the research, design and development of new tobacco products has become a hot research field in the international tobacco industry. [0003] As a low-temperature heat-not-burn cigarette in ...

AI Technical Summary

Problems solved by technology

Low-temperature heat-not-burn cigarette products are mainly composed of cigarettes and heating devices. The cigarettes are basically the same as ordinary cigarettes. The heating methods mainly include central heating and external heating. Due to the low temperature of the heat source (200-300°C ), coupled with the poor thermal conductivity of cigarette paper and tobacco, resulting in insufficient smoke production under low temperature conditions, insufficient consumer satisfaction, and cigarette paper has burnt, yellow, and black phenomena

At present, there are related patents (201610913140.7, 201410437696.4, etc.) to improve the flame retardancy of cigarette paper for low-temperature cigarettes, which can effectively solve the phenomenon of burning, yellowing and blackening of cigarette paper, but it is difficult to fully release the flavor components in tobacco, and the amount of smoke is not enough. The problem of lack of satisfaction among consumers has not been solved
