Chinese cypress paper, preparation thereof, special equipment and cigarette obtained thereby

Abstract

The invention discloses tipping paper with fire retardance and a preparation method, a special device thereof and cigarettes packaged by the tipping paper. A back surface of the tipping paper is provided with a strong fire retardant titanium dioxide layer. The preparation step of the tipping paper is spraying / coating a titanate layer which is decomposed to a titanium dioxide layer in the presenceof water on the back surface of the tripping paper. The special device for the preparation method is obtained by reconstructing a tinfoil laminating machine or a roll coater and sequentially comprises an upper pull roll, a titanate coating roll for coating the titanate layer, a water decomposition roll on which the titanate layer is decomposed to a titanium dioxide layer in the presence of the water, an adjustable manual roll and a drying drum. The safe cigarette which is produced by the tipping paper and provided with a self extinguishing cigarette end comprises a cigarette filter tip and a cigarette body. The back surface of the packaging tipping paper of the cigarette filter tip is provided with the strong fire retardant titanium dioxide layer. The cigarette end become self extinguishing completely when the burning cigarette burns to the tipping paper part, and the self extinguishing rate is 100%, thus effectively preventing and reducing fire resulting from burning cigarette ends.

Description

technical field [0001] The invention relates to a strong flame-retardant tipping paper, a preparation method thereof, a special device and the resulting cigarette butt self-extinguishing safety type. Background technique [0002] According to the data released by the 119 fire website, 68% of the fires in my country are caused by unextinguished cigarette butts. According to statistics from the Ministry of Health, my country is the country with the largest number of smokers in the world, with 350 million people. According to this figure, at least 3.5 billion cigarette butts are discarded in my country every day. Discarding unextinguished cigarette butts is another bad habit of some smokers. Discarded cigarette butts often burn to about 3.5 centimeters from the cigarette. This part happens to be close to the tipping paper of the filter tip. The classic 100 Hongtashan cigarettes produced by Hunan China Tobacco Industry Co., Ltd. have a total length of 84mm, the length of the ti...

Problems solved by technology

When smoking this kind of cigarette, when the cigarette burns to the position where the flame-retardant material 4 is set, the cigarette butt isolates the air or wraps the cigarette butt tightly together due to the flame-retardant effect of the material 4, so that the cigarette butt is extinguished, but the cigarette needs to be provided with a flame-retardant material. Combustible materials, inconvenient production

Chinese patent CN2536057 discloses a self-extinguishing cigarette, which is to put an impermeable water-containing body inside the connection between the cigarette and the filter, and achieve the purpose of self-extinguishing by burning. The cigarette needs to be equipped with a water-containing body, which is inconvenient to produce
