Problems solved by technology

The disadvantage is that arsenic disulfide is easy to produce toxic impurity arsenic pentoxide, and the sulfuric acid that forms smoke is inhaled by users, which makes users feel uncomfortable. It is becoming more and more difficult to mine arsenic disulfide minerals, and the difficulty of purchasing is gradually increasing.

preparation example Construction

[0036] The preparation method of the double nail propellant is as follows: mixing nitrocellulose and nitroguanidine.

[0037] The nitrocellulose of the present invention is collodion; the English name is Collodion, and the Chinese alias is collodion; the CAS number is 9004-70-0, and the molecular formula is C 6 h 8 N 2 o 9 , for making cultural and educational supplies, daily necessities, instrument signs, etc.; for ink, leather, various lacquers, rubber caps, typing stencils, etc.; for the pharmaceutical industry, photographic negatives, photographic negatives and leather manufacturing.

[0038] Nitroguanidine (Nitroguanidine) of the present invention, molecular formula is CH 4 N 4 o 2 , commonly used in pesticides, pharmaceutical intermediates, and automotive airbags.

[0039] The smoking composition provided by the invention uses the double nail propellant as the main energy source, and lactose as the combustible agent.

[0040] The smoking composition provided by th...

Embodiment 1

[0074] Mix 40g red dye, 20g lactose and 5g phenolic resin binder, granulate, and dry at 50°C to obtain the mixture; mix the mixture with 20gKClO 3 It is mixed with 10 g of double nail propellants prepared by mixing nitrocellulose and nitroguanidine to obtain a smoking composition.

[0075] When the smoking composition is excited, light red smoke can be seen; the sound decibel measurement is 90db; the entire burning time is 10ms.

Embodiment 2

[0077] Mix 45g red dye, 25g lactose and 8g phenolic resin binder, granulate, and dry at 50°C to obtain the mixture; mix the mixture with 25gKClO 3 It is mixed with 15g of double nail propellant prepared by mixing nitrocellulose and nitroguanidine to obtain a smoking composition.

[0078] When the smoking composition is excited, pink smoke can be seen; the sound decibel measurement is 80db; the entire burning time is 13ms.

Abstract

The invention provides a smoke composition. The smoke composition is prepared from the following components in parts by weight: 40-50 of dye, 20-30 of lactose, 20-30 of KClO3, 10-20 of double-nail propellant powder, and 5-10 of adhesive, wherein the double-nail propellant powder comprises collodion and nitroguanidine. The double-nail propellant powder serves as the main energy source of the smoke composition, the lactose serves as a combustible agent, and the dye serves as a coloring agent. Due to external stimulation, the double-nail propellant powder burns furiously, generating sound and releasing a large quantity of heat so as to enable KClO3 and lactose to react to produce a lot of gas and energy, the heat sublimates the dye quickly, gas fuel scatters in air along with CO1, CO2, vapor and other gases produced by the reaction between KClO3 and lactose and condenses into solid dye particles when being cooled in air, and the solid dye particles are reflected by sunshine so as to form visible smoke. The smoke composition provided in the invention is non-toxic and harmless and produces smoke rapidly, the raw materials are easy to get, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of smoking agents, in particular to a smoking composition, a preparation method thereof and a cartridge. Background technique [0002] The smoke agent is mainly used in sports meeting signal flares or training simulation exercises to send instructions, transmit signals and knowledge targets, etc., and has a certain smoke effect when it is fired. [0003] In the prior art, calcium phosphate, arsenic disulfide, lead stefanate, potassium chlorate and phenolic resin are mechanically mixed as a fuming agent. Its disadvantages are that arsenic disulfide is easy to produce toxic impurity arsenic pentoxide, and the sulfuric acid that forms smoke is inhaled by users, which makes users feel uncomfortable. It is becoming more and more difficult to mine arsenic disulfide minerals, and the difficulty of purchasing gradually increases. Contents of the invention [0004] In view of this, the technical problem to be solv...
