Abstract
The invention relates to a kind of firing powder and postponing powder for rocket-firework. The component proportions of firing powder are as follows: weight percent of gunpowder is 20-60%; mass percent of oxidant is 30-50%; mass percent of combustible matter is 10-30%. The component proportions of postponing medicine can be described as follows: weight percent of resin is 10-25%; weight percent of oxidant is 60-84.5%; weight percent of combustible matter is 5-15%; weight percent of solidifying agent is 0.1-5%. In the two medicines mentioned above, the firing medicine is made in following steps: desiccate gunpowder, oxidant, and combustible matter respectively, pass 120 order sieve; and after weighting out it according to the proportion, pass 80 order copper sieve; and at last, compound it repeatedly and for several times. Manufacturing method of the postponing medicine is that: desiccate combustible matter and oxidant respectively, pass 120 order sieve; after weighting out it according to the proportion, pass 80 order copper sieve; then compound it repeatedly and for several times, and after, add epoxy resin, then mediate by 10-30 minutes; at last, add solidifying agent according to the proportion, mediate by 5-20 minutes again.
Description
Technical field
The present invention relates to ignition powder and delay agent that a kind of fireworks are used, relate in particular to two kinds of ignition powder and delay agents that are complementary and use.
The invention still further relates to the preparation method of above-mentioned ignition powder and delay agent.
Background technology
The priming charge that uses of the propelling agent used of pyrotechnics is No. 3 small-grain black powders now, and this priming charge combustion speed is fast, and moment promptly produces a large amount of hot gass and some solids, by hot gas and the solids propelling agent that ignites.Because its combustion speed solids fast, that generate are few, cause the propelling agent can not instantaneous ignition and set up the required pressure of its stable burning, No. 3 small-grain black powder instancies of combustion produce a large amount of gas and form a pressure spike before propelling agent are set up stable burning, often greater than the pressure of propelling agent stable burning, this just requires housing to have suitable intensity to the peak pressure that is produced.
At present used delay agent only requires that its flame sensitivity is good, flameholding, ignition ability be strong, and its compressive strength is not then had particular requirement.The required pressure of double-base propellent stable burning is generally 6～7Mpa, and in the case, general delay powder during propellant combustion, easily leans on delay powder by puncture because of there not being sufficient intensity, thereby can not keep housing seal to cause the propelling agent can't trouble-free burning.
Summary of the invention
The object of the present invention is to provide a kind of priming charge, suitably reduce its combustion speed, increase the solids product that improves ignition ability, thereby under the situation that does not reduce ignition ability, reduce the combustion pressure peak of priming charge, and make it become the initial pressure of propelling agent stable burning.
The delay powder that another object of the present invention is to provide a kind of and above-mentioned priming charge to be complementary and to use, make it both satisfy the general requirement of delay powder, can guarantee again under the pressure of 6～7Mpa, still to keep housing seal, thereby a kind of extension method and approach under elevated pressures (10Mpa) is provided.
Another purpose of the present invention is to provide above-mentioned two kinds of medicaments preparation methods.
For achieving the above object, the present invention is by adding combustiblematerials (wood charcoal powder, aluminium-magnesium alloy powder, aluminium powder, magnesium powder etc.), oxygenant (KClO in black powder
4, NH
4ClO
4, KNO
3, Sr (NO
3)
2, NaNO
3, Ba (NO
3)
2, KClO
3) etc.By regulate combustiblematerials, oxygenate content is regulated combustion speed, and the pressure spike of its generation and pressure spike that propelling agent is set up stable burning are reached unanimity.
The prescription of ignition powder is by weight as follows:
Black powder 20-60%
Combustiblematerials 10-30%
Oxygenant 30-50%
The preparation method of ignition powder: the raw material of above-mentioned oven dry mixed in proportion get final product.
Delay agent provided by the invention, it consists of: resin (resol, Resins, epoxy etc.), oxygenant (NH
4ClO
4, KNO
3, Sr (NO
3)
2, NaNO
3, Ba (NO
3)
2, KClO
3), combustiblematerials (aluminium powder, aluminium-magnesium alloy powder) and solidifying agent (quadrol etc.).
The prescription of delay powder is by weight as follows:
Resin 10-25%
Combustiblematerials 5-15%
Oxygenant 60-84.5%
Solidifying agent 0.1-5%
The preparation method of delay powder: join in the resin after oxygenant and combustiblematerials mixed in proportion, after stirring, add solidifying agent in proportion, get final product after stirring.
The present invention adds oxygenant in above-mentioned two kinds of medicaments effect is to provide necessary oxygen for combustible object in the medicament combustion processes.The effect that adds combustiblematerials provides the combustiblesubstance of launching in the medicament combustion processes, and its burning is normally carried out.Make resin solidification produce enough intensity by adding an amount of solidifying agent.Resin acts as a fuel and binding agent.
Compare with the priming charge in the propelling agent of using always, priming charge involved in the present invention has added the metal combustiblematerials, and its burning generates scorching hot metal oxide, thereby has strengthened the ignition ability of priming charge; The pressure spike that priming charge burning of the present invention produces overlaps with the pressure spike that propellant combustion forms, and by suitably adjusting prescription, this priming charge can be used for lighting of other propelling agent.Compare with delay powder commonly used, delay powder involved in the present invention is good except the flame sensitivity with common delay powder, flameholding, have enough characteristics such as ignition ability, also have the good characteristics of compressive strength, can guarantee that propelling agent is in normal operating pressure (6～7MPa) times stable burning.
