Abstract

This invention relates to a fireworks used rosy cloud flashing stars and production methods. It use pyrotechnics agent to produce. The crude drug of this rosy cloud flashing stars is in powder form, composited by the black powder 40-60, antimony sulfide 6-8, 18-22 barium nitrate, aluminum powder 10-20, 3-6 dextrin (according to the weight). The steps of produce rosy cloud flashing stars are: select raw material of particle size is not more than 120 head, mixing, and then dilute by appropriate amount of alcohol, modeling, and dry. The stars have good chemical stability, hygroscopicity small, harmless to the human body.

Description

A kind of glowing ray flash star for fireworks and preparation method thereof

Technical field

The present invention relates to pyrotechnics composition and preparation method thereof, be meant a kind of glowing ray flash star for fireworks and preparation method thereof especially.

Background technology

China is traditional fireworks power, and the research and the production history of fireworks are long, have won fame both at home and abroad, development along with world economy, the raising of living standards of the people, culture life is also developed on an unprecedented scale, and it is colorful to become increasingly abundant, in grand celebrations activity, large-scale competitive sports, cultural activity, major holiday, and even wedding and funeral arrangements marriage, enterprise's opening, people will add lustre for it with the mode of setting off fireworks, still, along with the raising of people's level of cultural life, the requirement of firework effect is also improved constantly.Celestial body is to classify according to all kinds position feature of pyrotechnic composition goods, though the normally used celestial body that has five types: cylindrical celestial body, cube celestial body, boxlike celestial body, compacting celestial body and spherical celestial body.But adopt different pharmaceutical chemicalss, but can obtain the infinite effect of conversion.In the fireworks technology, press for the R and D pharmaceutical preparations, still find no glowing ray flash star in the firework product at present.

Summary of the invention

The objective of the invention is to provide the making method of a kind of glowing ray flash star and this glowing ray flash star.

Technical scheme of the present invention is such, and a kind of glowing ray flash star for fireworks comprises rays of sunlight look, and its raw material is powdered, by

Black powder 40-60

Antimony sulfide 6-8

Nitrate of baryta 18-22

Aluminium powder 10-20

Dextrin 3-6

Form by weight ratio.

Make the method for described glowing ray flash star, its step is as follows:

A) screening mixes: the dried powder screening of each component of raw material is not more than 120 purpose particles for particle diameter, and with the raw material powder thorough mixing;

B) dilution: make thinner with suitable quantity of water, the dilution raw material powder;

C) mix moulding: raw material powder dilution is mixed, make moulding, described celestial body shape is made as arbitrary shape as required, preferably cylindrical, square, box-like or sphere;

D) drying.

Beneficial effect of the present invention: oxygenant commonly used mainly is potassium perchlorate and nitrate of baryta in the pyrotechnic composition at present, the purpose of using oxygenant in pyrotechnics composition is to make combustiblematerials produce violent redox reaction, so that produce heat and gaseous product, form burning and blast and other suitable pyrotechnic effect, number average has certain moisture mostly.Black powder has had very long history as explosive, the black powder that uses in pyrotechnics usually has following ingredients: saltpetre, charcoal and sulphur, it remains the basis of pyrotechnics industry so far, it is characterized in that being easy to light, and under the situation that temperature and pressure change significantly, having good biography bad temper and adaptability, its chemical property is very stable under the normal temperature.Contained saltpetre is oxygenant in the black powder among the present invention, and nitrate of baryta is not only oxygenant, still good green luminescence agent, and low price.

The character that ideal fuel should possess: have enough heat effect, reaching best pyrotechnic effect, good security, storge quality is stable, and cost is low, easily pulverizes; High performance fuel commonly used has aluminium powder, magnesium powder, magnesium aluminum-alloy powder titanium valve, silica flour, sulphur, charcoal etc., contains sulphur in the black powder among the present invention, charcoal is good fuel, and aluminium powder not only can be used as fuel, goes back the white-light emitting agent.

So-called quick-fried shwoot refers to that only with medicament is made into the pearl body, can break out and flash after lighting, and similar thunder and lightning flash of light is the same, rather than it is luminous to burn, and usually this flash of light is called snuff in the fireworks industry, and the pearl body that can produce snuff is called flash card.Snuff is a kind of peculiar effect of firework product, and it has the special appreciation effect of luminous, sound equipment, outburst and glory quaternity, and scintillation effect is the effect that the clinker process of cooling that produced during by black powder and antimony, aluminium burning is produced among the present invention.

Dextrin is the partial hydrolysate of starch, because it is water-soluble, has good adhesive property simultaneously, incendivity, in pyrotechnics as a kind of caking agent, when married operation, common way be add percentum dextrin dry powder in the component of celestial body, before the celestial body moulding, add water then again.Because it has water absorbability, so usage quantity had better not be above 5%, and some are relatively good less.Dextrin is insoluble to ethanol, when celestial body is made, add ethanol and can promote fast doing in water, but do not surpass 30%, otherwise the quality of adhesion of dextrin will decrease.

In sum, stable in properties of the present invention stores transportation safety, presents spike of rice state fancy effect when setting off, and produces bright-coloured rays of sunlight color, has increased a kind of color of elegance for firework display.

Embodiment

Example 1, a kind of glowing ray flash star for fireworks comprise rays of sunlight look, and its bulk drug is Powdered, by black powder 40-60, and antimony sulfide 6-8, nitrate of baryta 18-22, aluminium powder 10-20, dextrin 3-6 forms by weight ratio.With reference to the proportioning raw materials table, enumerated 3 kinds of mix proportion schemes in the table, show by setting off experiment, the celestial body that adopts proportioning 2 to make, color is more gorgeous when setting off, and scintillation time is longer, and effect is better than proportioning 1 and proportioning 3.

The proportioning raw materials table

Raw material	Proportioning 1	Proportioning 2	Proportioning 3
				Black powder	40	53	60
Antimony sulfide	6	7	8
				Nitrate of baryta	18	20	22
Aluminium powder	20	15	10
				Dextrin	6	5	3

Example 2, the method for making described glowing ray flash star, its step is as follows:

A) screening mixes: the dried powder screening of each component of raw material is not more than 120 purpose particles for particle diameter, and with the raw material powder thorough mixing;

B) dilution: make thinner with suitable quantity of water, the dilution raw material powder;

C) mix moulding: raw material powder dilution is mixed, make moulding, described celestial body shape is made as arbitrary shape as required, preferably cylindrical, square, box-like or sphere;

D) drying: adopt oven drying at low temperature, dry or seasoning all can.
