Problems solved by technology

[0002] At present, the inner core of the red flash star used in fireworks such as fireworks shells and potted flowers is usually made of red light agent strontium nitrate mixed with ammonium perchlorate, sulfur, magnesium powder, paraffin and other agents. , and then wrapped in the package medicine and igniter to make the red flash star, although it can produce better results, but there is a fatal shortcoming, that is, the chemical raw materials strontium nitrate and perchloric acid used in the inner core of the red flash Ammonium has strong hygroscopicity and is easy to cause the oxidation of magnesium powder. Therefore, the red flash star produced is poor in stability and the color is very bright when it is set off. Especially in the southern area where the air humidity is high and it is the main production area of ​​fireworks. Stars with strong hygroscopicity not only seriously affect the quality and discharge effect of fireworks products, but also have high production costs and poor safety performance, so they are not suitable for production

Embodiment 1

[0009] 70 parts by weight of strontium carbonate, 20 parts by weight of potassium dichromate and 10 parts by weight of rare metal materials are mixed to make red flashing agent, and then 30 parts by weight of potassium perchlorate as oxidant, 20 parts by weight of magnesium powder as combustible agent, as Mix 5 parts by weight of strong powder of the adhesive with 45 parts by weight of the above-mentioned red flashing agent, then add 20 parts by weight of water as a dilution solvent and mix evenly, place it in a bright bead granulator, and make it into small bead-shaped particles. Adopt natural drying (can be dried with steam) to completely dry, obtain the red flash inner core of the diameter 3.5mm that is made of the red flash star of the present invention; Place the red flash inner core after the full dry again in the bright bead granulator and use The pre-prepared Chinese medicine is packaged and granulated. The thickness of the Chinese medicine layer is 1.5mm. Thickness is...

Embodiment 2

[0011] 65 parts by weight of strontium carbonate, 23 parts by weight of potassium dichromate and 12 parts by weight of rare metal materials are mixed to make a red flashing agent, and then 26 parts by weight of potassium perchlorate as an oxidant, 18 parts by weight of magnesium powder as a combustible agent, as Mix 6 parts by weight of strong powder of the adhesive with 50 parts by weight of the above-mentioned red flashing agent, then add 20 parts by weight of water as a dilution solvent and mix evenly, place it in a bright bead granulator, and make it into small bead-shaped particles. Adopt natural drying (can be dried with steam) to completely dry, obtain the red flash inner core of the diameter 5mm that is made of the red flash star of the present invention; The prepared Chinese medicine is packaged and granulated. The thickness of the Chinese medicine layer is 1.5mm. After natural drying (can be dried by steam), the pre-prepared igniter is used to wrap and granulate. The ...

Embodiment 3

[0013] 60 parts by weight of strontium carbonate, 25 parts by weight of potassium dichromate and 15 parts by weight of rare metal materials are mixed to make a red flashing agent, and then 28 parts by weight of potassium perchlorate as an oxidant, 16 parts by weight of magnesium powder as a combustible agent, as Mix 6 parts by weight of strong powder of the adhesive with 50 parts by weight of the above-mentioned red flashing agent, then add 20 parts by weight of water as a dilution solvent and mix evenly, place it in a bright bead granulator, and make it into small bead-shaped particles. Adopt natural drying (can be dried with steam) to completely dry, obtain the red flash inner core of the diameter 7mm that is made of the red flash star of the present invention; The prepared Chinese medicine is wrapped and granulated, and the thickness of the middle medicine layer is 2mm. After natural drying (can be dried by steam), the pre-prepared igniter is used to wrap and granulate. The ...

Abstract

The invention discloses a red flashing star fro manufacturing fireworks, which is made up of red flashing inner core, middle contained powder and firing powder, the red flash inner core uses red flash agent, potassium perchlorate, magnesium powder and strong flour as primary elements, the contents are 45-50%, 26-30%, 16-20%, 5-6% respectives above mentioned materials are blended together, and adds in some water as diluter, and produces them into small ball of red flash inner core, then they are palletized according to the powder, then carries on drying and acquires the product. The red flash agent is the compound of strontium carbonate, potassium dichromate, and rare metal materials. The invention has characters of non humidifying, stable, fresh, and low cost.

Description

technical field [0001] The invention relates to a colored flame agent widely used in fireworks products, and more particularly relates to a red sparkling star used in making fireworks. Background technique [0002] At present, the inner core of the red flash star used in fireworks such as fireworks shells and potted flowers is usually made of red light agent strontium nitrate mixed with ammonium perchlorate, sulfur, magnesium powder, paraffin and other agents. , and then wrapped in the package medicine and igniter to make the red flash star, although it can produce better results, but there is a fatal shortcoming, that is, the chemical raw materials strontium nitrate and perchloric acid used in the inner core of the red flash Ammonium has strong hygroscopicity and is easy to cause the oxidation of magnesium powder.
