Cigarette paper with low ignition tendency and preparation method

Abstract

The invention discloses cigarette paper with low ignition tendency and a preparation method. The cigarette paper comprises common cigarette paper manufactured by a papermaking process; and a coating liquid film consisting of film forming agent, viscosity regulator and filler is printed on the inner surface of the common cigarette paper. The preparation method comprises the following steps of: (1) preparing the common cigarette paper of certain specification; (2) preparing the filler into 40 to 60 percent suspension, and stirring uniformly; (3) adding the viscosity regulator component into the (2) at normal temperature to prepare 2 to 4 mass percent aqueous solution, and stirring for 10 minutes; (4) adding the film forming agent component into the (3) at normal temperature to prepare 25 to 35 mass percent aqueous solution, and stirring for 20 minutes; and (5) adding the sizing material prepared in the (4) on the surface of the cigarette paper through a silk screen in certain interval by adopting a printing and coating mode. When the cigarette paper is burnt to a coated strip in the atmospheric environment, the cigarette has low extinguishing rate and even is not extinguished; and under the standard test condition, the filter paper of contact matrix has high extinguishing rate, and meanwhile, the cigarette paper has no obvious adverse effects on the cigarette smoke and the smoking quality.

Description

technical field [0001] The invention belongs to the field of cigarette processing, in particular to a method for preparing cigarette paper with low ignition tendency. Background technique [0002] According to statistics from the US Consumer Product Safety Commission, most of the fires in major fires are caused by placing burning cigarettes on beds or sofa upholstered furniture, which directly leads to 20% of fire deaths. About 900 people die each year, more than 250 people are injured, and the economic loss is as much as 400 million US dollars. The main purpose of proposing cigarettes with low ignition tendency internationally is to reduce fire losses. However, international large-scale cigarette paper manufacturers such as Moody International Group and Wattens Paper Co., Ltd. have introduced cigarette paper that reduces the risk of fire. The current low-ignition tendency cigarettes are provided with flame-retardant tapes on the cigarette paper to make the Cigarettes can ...
