Abstract
The invention relates to an efficient flame-retardant coating for low-ignition-tendency cigarette paper. A method for preparing the efficient flame-retardant coating for the low-ignition-tendency cigarette paper comprises the following steps of: adding aluminum hydroxide into edible alcohol with the volume rate of 95 percent, wherein the mass rate of the aluminum hydroxide to the edible alcohol is 1:25-1:50; and then adding propylene glycol as a dispersing agent with same mass as that of the aluminum hydroxide, violently stirring for 2h, then adding ethyl cellulose so that the viscosity of a gel solution reaches 30-40s, continuously stirring till the ethyl cellulose is completely dissolved to form a stable gel suspension, namely the efficient flame-retardant coating for the low-ignition-tendency cigarette paper. According to the invention, the low-ignition-tendency cigarette paper coating with efficient flame-retardance is developed by taking the aluminum hydroxide and the ethyl cellulose as flame-retardant materials, and the alcohol and a little amount of propylene glycol as dispersing carriers. The aluminum hydroxide and the ethyl cellulose used in the efficient flame-retardant coating are products meeting cigarette safety product standards, are low in cost and can effectively meet the requirements of the low-ignition-tendency cigarette paper coating.
Description
Technical field
The present invention relates to technical field of cigarettes, specifically a kind of highly effective flame-retardant coating that is used for the cigarette paper of low ignition tendency.
Background technology
Smoking and disaster hidden-trouble have caused widely already to be paid close attention to.National Fire Protection Association's fire statistics data for many years shows, all falls and causes in bed or on the decorative article by lighting cigarette at the most calamitous fire of the U.S..Therefore, (Low Ignition Propensity, LIP) main purpose of cigarette is exactly in order to reduce the loss of fire to propose low ignition tendency in the world.
The central temperature of cigarette end is up to 800-900
oC, its surface temperature also has 300-400
oC, and the burning-point of general solid combustible is 200
oAbout C.Therefore, the smoker careless or sleeping in, when the cigarette that does not extinguish drops on clothes, furniture or the paper, just be very easy to cause fire.
The New York, United States that continues takes the lead in through decree; Require this state from June 28th, 2004 all cigarette of selling in market total length burning ratio can not surpass 25%; After becoming in the world the area that first rigid and absolute enforcement reduces igniting property of cigarette standard, Canadian government, California, USA etc. has also been announced identical cigarette fire safety standard in succession.The legislation to the cigarette of low ignition tendency has been accomplished in have an appointment 1/3rd state of the U.S. up to now, and research is also being set about by states such as European Union, Australia, South Africa, and expectation will be accomplished the legislation of the cigarette of low ignition tendency in 2010～2011 years.It is thus clear that the cigarette of low ignition tendency has become the research focus of international tobacco circle of present stage.
The LIP anti-flaming dope of different manufacturers use in the market has nothing in common with each other, and is main with starch and sodium alginate commonly.But coating processes commonly used is main with flexo and gravure generally in the cigarette manufacturing industry at present.Coated weight is all less relatively, is difficult to reach demand, needs a large amount of fund inputs and revise coating processes.Therefore, be necessary to develop the stronger coating of a kind of flame retardant effect, under the few situation of coated weight, still can reach the flame retardant effect that needs.
Summary of the invention
The purpose of this invention is to provide a kind of can under the condition that gravure applies, being coated on the cigarette paper, and the cigarette that reaches flame retardant effect is used anti-flaming dope.
The technical scheme of technical solution problem of the present invention is:
In the mixture of aluminium hydroxide and edible ethanol, stir the adding ethyl cellulose, make mixture form metastable turbid liquid.Its concrete grammar is: in the edible ethanol with aluminium hydroxide adding 95%; Both additional proportions are between the 1:25-1:50; (concrete additional proportion look cigarette body paper air permeability and decide), and the propylene glycol of quality such as adding and aluminium hydroxide is as dispersant, behind the vigorous stirring 2h; (the concrete addition of ethyl cellulose can be decided the demand of dope viscosity according to different gravure technique conditions to add ethyl cellulose; Gel solution viscosity reaches in the 30-40s scope, and the mass ratio that generally can select ethyl cellulose and ethanol is 3:50), continue to stir; Dissolve fully until ethyl cellulose, form the stabilizing gel turbid liquid and be described low ignition tendency cigarette paper highly effective flame-retardant coating.In order to guarantee the stability of coated product, this coating is vigorous stirring once more before use, makes it even, and then joins in the hopper of intaglio printing and use.
The present invention adopts aluminium hydroxide and ethyl cellulose as fire proofing, as dispersible carrier, has developed a kind of low ignition tendency cigarette paper coating of highly effective flame-retardant with ethanol and minor amounts of propylene glycol.Aluminium hydroxide, ethyl cellulose that the present invention uses are the product that meets cigarette safety article standard, and be cheap, can satisfy the requirement of low ignition tendency cigarette paper coating effectively.
