Abstract

The invention discloses a cigarette self-extinguishing liquid and a preparation method thereof. Under the temperature of 93 to 98 DEG C, 120 to 150 portions of PVA are added into 900 to 1000 portions of water by mass proportion and is fully stirred and mixed, then 130 to 160 portions of phosphoric acid is added under the condition of holding the temperature; then 65 to 100 portions of Chitosante are added and stirred; if more foams exist in the liquid, 0.2 to 0.3 portion of foam killer can be added. After the cigarette self-extinguishing liquid prepared by utilizing the method is coated on special paper for cigarette, the prepared cigarette can self-extinguish under any situation of stopping smoking and throwing, thus reducing fire source and reducing the happening rate of fire.

Description

A kind of cigarette self-extinguishing solution and preparation method thereof

Technical field

The present invention relates to a kind of cigarette and use self-extinguishing liquid and preparation method thereof.

Background technology

The fire that afterflame caused after cigarette was dropped has become " the No.1 killer " of initiation fire in the world today, serious threat people's the security of the lives and property, the annual whole world have millions of life and multi-million dollar property owing to the fire that afterflame cigarette causes loses.Cigarette causes that leading cause of fire is after burning cigarette is dropped, in the time of afterflame, meet combustibles and cause, therefore the method for the most basic minimizing fire is exactly to put out certainly after burning cigarette is dropped, and does not give the chance of cigarette afterflame, eliminates the fire source.

Summary of the invention

The object of the invention is to provide a kind of self-extinguishing liquid that applies on the cigarette dedicated paper, can extinguish naturally very soon after disconnected suction abandons through the cigarette that self-extinguishing liquid of the present invention was handled, and reduces the fire occurrence probability, and nontoxic to human body.Cigarette is tasteless after the processing of self-extinguishing liquid, dehumidify, preserve moisture, and cigarette paper toughness increases, and is tear-resistant.

Cigarette self-extinguishing solution of the present invention, mainly form by PVA, edible phosphoric acid, chitin and water, each composition quality umber is respectively: PVA is 120～150 parts, edible phosphoric acid is 130～160 parts, chitin is 65～100 parts, water is 900～1000 parts, if self-extinguishing liquid has more foam before encapsulation, can add 0.2～0.3 part of defoamer in solution.

Cigarette self-extinguishing solution of the present invention prepares as follows:

(a) 900～1000 parts of water are heated to 93～98 ℃, 120～150 parts PVA are added in the entry, stir and fully mix;

(b) maintain the temperature in 93～98 ℃ of scopes, in the solution of (a) step preparation, add 130～160 parts of edible phosphoric acids and stir;

(c) maintain the temperature in 93～98 ℃ of scopes, in the solution of (b) step preparation, add 65～100 parts chitin, treat after stirring that solution temperature reduces to barrelling sealing behind the normal temperature.

When if more foam is arranged in the solution, can before the solution barrelling, add defoamer and stir.After cigarette self-extinguishing solution prepares, with its spraying, calendering or drip a coating method and be coated on the cigarette dedicated paper and can make the cigarette that to put out certainly.

The self-extinguished cigarette that utilizes the present invention to make all can put out under the situation that any disconnected suction abandons certainly, has reduced the fire source, has reduced the fire odds.

The specific embodiment

Below in conjunction with example the present invention is specifically described:

1,950 parts of water is heated to 96 ℃, starting mixer stirs, slowly add PVA120 part then, 51 rev/mins of mixing speeds keep 96 ℃ of water temperatures to stir and add 130 parts of edible phosphoric acids after 45 minutes, adding chitin immediately stirred 22 hours for 65 parts, in the observation solution whether too many bubble is arranged,, can add silicone defoaming agent and stir for 0.2 part if too many foam is arranged, just do not added defoamer if foam is few, treated that solution reduces to barrelling sealing behind the normal temperature.

2,980 parts of water are heated to 98 ℃, starting mixer stirs, slowly add PVA150 part then, 52 rev/mins of mixing speeds keep 98 ℃ of water temperatures to stir and add 160 parts of edible phosphoric acids after 45 minutes, adding chitin immediately stirred 22 hours for 80 parts, in the observation solution whether too many bubble is arranged,, can add silicone defoaming agent and stir for 0.3 part if too many foam is arranged, just do not added defoamer if foam is few, treated that solution reduces to barrelling sealing behind the normal temperature.

3,1000 parts of water are heated to 93 ℃, starting mixer stirs, slowly add PVA150 part then, 52 rev/mins of mixing speeds keep 93 ℃ of water temperatures to stir and add 160 parts of edible phosphoric acids after 45 minutes, adding chitin immediately stirred 22 hours for 100 parts, in the observation solution whether too many bubble is arranged,, can add the polyethylene glycol ether defoaming agent and stir for 0.3 part if too many foam is arranged, just do not added defoamer if foam is few, treated that solution reduces to barrelling sealing behind the normal temperature.

Claims
