Abstract

The invention relates to flickering goldenarmor tail combined fireworks and a preparation method of the flickering goldenarmor tail combined fireworks, belonging to the technical field of fireworks and crackers products. The flickering goldenarmor tail combined fireworks can be used for manufacturing overhead combined fireworks products of various specifications. According to the flickering goldenarmor tail combined fireworks, sodium bicarbonate is used for replacing sodium oxalate in common goldenarmor tail combined fireworks; various raw materials are prepared based on a certain ratio to obtain the pyrotechnic composition with fireworks tail effect, so as to obtain the combined fireworks; when in setting off, the pyrotechnic composition effective product is ignited and emitted to the high air; the pyrotechnic composition generates melt during being burnt; the melt is blown out through the gas produced during the burning, and is residual on the running track and continuously burnt, and the effect of flickering goldenarmor tail is shown on the running track; compared with common flickering goldenarmor tail combined fireworks, the flickering goldenarmor tail combined fireworks provided by the invention has larger single goldenarmor tail flower during the burning, and the whole goldenarmor tail flower is longer.

Description

A kind of flicker tortoise beetle tail combined firework and preparation method thereof

Technical field

The present invention relates to a kind of flicker tortoise beetle tail combined firework and preparation method thereof, belong to fireworks and firecrackers product technical field, this invention can be used for making the high-altitude combined firework product of all size.

Background technology

What in prior art, in tortoise beetle tail combined firework, use is sodium oxalate, and these fireworks tortoise beetle decorative pattern at the end of a poem, article, etc. where there is a small blank space in the time setting off is little.

Summary of the invention

The object of the invention is in order to propose a kind of flicker tortoise beetle tail combined firework and preparation method thereof,

The object of the invention is to be achieved through the following technical solutions.

A kind of flicker tortoise beetle tail combined firework of the present invention, these fireworks comprise saltpetre, sulphur, charcoal, sodium bicarbonate and magnesium aluminum-alloy powder, calculate with the total mass of fireworks, the mass content of each several part is:

The preparation method of a kind of tortoise beetle tail combined firework that glimmers of the present invention, concrete steps are:

1) saltpetre, sulphur, charcoal, sodium bicarbonate are crossed together with magnesium aluminum-alloy powder to 40 mesh standard sieves and mixed, obtain powder mix;

2) in the powder mix obtaining in step 1), add the acetone soln of nitro-cotton (to be commonly called as anti-tidewater, the mass concentration of the acetone soln of nitro-cotton is 2%-6%, be that nitro-cotton is as solute, acetone soln is as solvent), the quality of the acetone soln of the nitro-cotton adding is 5%-20% of powder mix quality, and mix, then become to set the pyrotechnic composition effect part of shape by Mould Machining, airing; (note: the acetone soln volatilization of nitro-cotton is very fast, and the acetone volatilizing has certain toxicity, should note ventilating and should take measures to prevent acetone volatilization as far as possible while therefore operation);

3) assembling finished product

By common combined firework production technique processing combined firework paper web, cross mud at the bottom of, sticky row, firing line is installed, in each fireworks paper tube, pack successively propelling charge, step 2 into) in the effect part and the scraps of paper of blocking up that obtain, pack and case, obtain the finished product of combined firework.

Beneficial effect

The present invention is to have replaced the sodium oxalate in conventional tortoise beetle tail combined firework with sodium bicarbonate, by the various starting material pyrotechnic composition of mixed preparing combined firework tail effect by a certain percentage, be made into combined firework, pyrotechnic composition effect part while setting off is lighted and by transmitted at high speed, when pyrotechnic composition burning, produce melts, the gas blow-out of the burned generation of melts is retained on its running orbit and burns away, on its running orbit, there is flicker tortoise beetle tail effect, when this invention is seted off than conventional flicker tortoise beetle tail combined firework, the monolithic tortoise beetle decorative pattern at the end of a poem, article, etc. where there is a small blank space is larger, the entirety tortoise beetle decorative pattern at the end of a poem, article, etc. where there is a small blank space is longer.When the present invention sets off than conventional flicker tortoise beetle tail combined firework, the monolithic tortoise beetle decorative pattern at the end of a poem, article, etc. where there is a small blank space is larger, and the overall tortoise beetle decorative pattern at the end of a poem, article, etc. where there is a small blank space is longer.

Embodiment

Below in conjunction with embodiment, the present invention will be further described.

Embodiment

The glimmer combined firework preparation method of tortoise beetle tail, concrete steps are:

1) take 50g saltpetre, 15g sulphur, 10g charcoal, 10g magnesium aluminum-alloy powder and 15g sodium bicarbonate, cross together 40 mesh standard sieves and mix, obtain powder mix;

2) in the powder mix obtaining in step 1), add the acetone soln of 8g nitro-cotton (to be commonly called as anti-tidewater, the mass concentration of the acetone soln of nitro-cotton is 4%), and mix, a certain amount of pyrotechnic composition (other pyrotechnic composition mixing plastic cloth wraps completely) that taking-up mixes, then become cylindrical pyrotechnic composition effect part, airing by Mould Machining.In acetone soln, the mass concentration of acetone is 37%.

3) assembling finished product

By common combined firework production technique processing combined firework paper web, cross mud at the bottom of, sticky row, firing line is installed, in each fireworks paper tube, pack successively propelling charge, step 2 into) in the effect part and the scraps of paper of blocking up that obtain, pack and case;

The above-mentioned combined firework finished product preparing is placed on spaciousness, smooth ground and is seted off, and effect part is lighted and is gone up to the air by transmitted at high speed, occurs flicker tortoise beetle tail effect on its running orbit.

Claims (1)

1. the glimmer combined firework preparation method of tortoise beetle tail, is characterized in that concrete steps are:

1) take 50g saltpetre, 15g sulphur, 10g charcoal, 10g magnesium aluminum-alloy powder and 15g sodium bicarbonate, cross together 40 mesh standard sieves and mix, obtain powder mix;

2) in step 1) in add the acetone soln of 8g nitro-cotton in the powder mix that obtains, and mix, take out a certain amount of pyrotechnic composition mixing, then become cylindrical pyrotechnic composition effect part, airing by Mould Machining; In acetone soln, the mass concentration of acetone is 37%;

3) assembling finished product

By common combined firework production technique processing combined firework paper web, cross mud at the bottom of, sticky row, firing line is installed, in each fireworks paper tube, pack successively propelling charge, step 2 into) in the effect part and the scraps of paper of blocking up that obtain, pack and case;

The above-mentioned combined firework finished product preparing is placed on spaciousness, smooth ground and is seted off, and effect part is lighted and is gone up to the air by transmitted at high speed, occurs flicker tortoise beetle tail effect on its running orbit.
