Abstract
The invention discloses a micro smoke gun propellant for fireworks, which comprises the following components in part by weight: 30-70 parts of nitrocotton, 5-30 parts of moistureproof ammonium perchlorate, 2-10 parts of reducing agent and 5-20 parts of high-nitrogen substance. The safety performance indexes of the micro smoke gun propellant for fireworks completely meet the requirements of the national standard. The micro smoke gun propellant for fireworks not only can meet the propelling requirement of the product, but also produces micro smoke when the gun propellant is combusted. According to the light transmittance detection result, the smoke quantity produced by the gun propellant is only about 30% of that of the traditional equivalent corresponding products.
Description
Technical field
The present invention relates to a kind of firework firework medicament, especially a kind of firework is with little cigarette propelling charge.
Background technology
In the prior art, fireworks all are to use black powder or other the similar black powders that is configured to saltpetre, charcoal, three kinds of compositions of sulphur with propelling charge.The smog that the black powder burning produces is too big, sets off the smog that product produces with other, makes to concentrate the large-scale fireworks party firework display effect of setting off to be had a strong impact on, and causes very big pollution to setting off a near urban air.
Summary of the invention
The object of the invention, the too big defective of smog when being to overcome existing black powder gun propellant combustion not only has only little cigarette after a kind of burning is provided, and the firework that can keep black powder emissivity, ignition quality, stability is with little cigarette propelling charge.
To achieve these goals, technical scheme of the present invention is: a kind of firework is made up of nitro-cotton, moistureproof ammoniumper chlorate, reductive agent, high nitrogen material with little cigarette propelling charge:
Reductive agent can adopt common reductive agent and/or high thermal reduction agent; Said high thermal reduction agent is a kind of or any multiple arbitrary proportion mixture of zirconium, titanium, aluminium, aluminum magnesium alloy, titanium hydride, zircoium hydride, calcium silicide powder, and its powder particle is wanted to cross 100 mesh standard sieves; Common reductive agent is a kind of or arbitrary proportion mixture of carbon, sulphur, silicon;
High nitrogen material is a kind of or arbitrary proportion mixture in amino guanidine nitrate, the nitroguanidine.Amino guanidine nitrate, molecular formula CH
9N
7O
3, nitrogen content 58.6%; Nitroguanidine, molecular formula CH
4N
4O
2, nitrogen content 53.8%.
Wherein nitro-cotton is made tamanori and reductive agent, and moistureproof ammoniumper chlorate provides the medicine needed oxygen that burns as oxygenant, and the reductive agent exothermic heat of reaction also produces the gas work done, and high nitrogen material produces nitrogen and stops smog to form.
Said firework uses the ratio of weight and number of little each component of cigarette propelling charge to be: nitro-cotton 30-70 part, moistureproof ammoniumper chlorate 5-30 part, reductive agent 2-10 part, high nitrogen material 5-20 part.All drug particles all must can pass through 100 mesh standard sieves.Above component is mixed, in order to avoid each composition of medicine is because of the layering of density difference.With an amount of damping of organic solvent, be molded into the medicine grain of all size.
Said organic solvent is an organic solvent commonly used, preferably uses one or more mixture of small molecules ester, ketone, alcohol.
Each constituent materials of the present invention all can be buied in firework raw material market or Chemical market according to said title; It is the single, double original washing powder of staple that the present firework industry of nitro-cotton adopts nitro-cotton mostly; Processed through operations such as fragmentation, interpolation tranquilizers by military retired single-base powder or double-base powder, its price is comparatively cheap.
To combine embodiment that the present invention is described further below.
Embodiment
Embodiment 1: after each starting material is crossed 100 mesh standard sieves, by ratio of weight and the number of copies, get 20 parts of moistureproof ammoniumper chlorate, 35 parts of single, double original washing powders, 5 parts of aluminium-magnesium alloy powders, 20 parts of nitroguanidines.Method with repeatedly sieving fast mixes each component, by ratio of weight and the number of copies, adds 20 parts of acetone solvent damping in per 100 parts of hybrid medicines, will fully knead after the adding, should not be too wet or too dried, be molded into the medicine grain of all size, drying.Said firework promptly prepares completion with little cigarette propelling charge.
Embodiment 2: be that with embodiment 1 difference said firework uses the component of little cigarette propelling charge and ratio of weight and number to be: 30 parts of moistureproof ammoniumper chlorate, 52 parts of single, double original washing powders, 5 parts of titanium hydride powders, 5 parts of waste of flax powdered carbons, 12 parts of amino guanidine nitrates.Adopt the ethyl acetate solvent damping, granulation.
