preparation example Construction

[0031] The preparation process of the micro-smoke lead includes the following steps:

[0032] (1) Pharmacy preparation for micro-smoke lead: fully mix 20%-80% of smokeless powder, 10%-40% of oxidizing agent, 0%-40% of metal powder and 0%-40% of inorganic salt according to a certain proportion and then sieve , to remove the oversized particles;

[0033] (2) Dissolve the uniformly mixed lead agent in an organic solvent, wherein the organic solvent can be selected from one of the following or used in cross-combination, including methanol, ethanol, isopropanol, n-butanol, methyl ether, ether, Methyl ether, acetone, ethyl acetate, butyl acetate;

[0034] (3) Feeding: Distribute the semi-fluid lead agent dissolved in organic solvent evenly on the lead paper by spraying;

[0035] (4) Forming: the lead paper coated with lead medicament semifluid is made into a lead to be dried by a lead machine;

[0036] (5) Drying: Put the lead wire made by the lead machine to be dried in a natura...

Embodiment 1

[0039] The preparation process of the fast lead is as follows:

[0040] (1) 100 mesh (average nitrogen content 12.5%) nitrocellulose 60%, ammonium perchlorate 20% and 120 mesh titanium powder 20% are fully mixed according to a certain ratio and sieved, and excessive particle size is removed;

[0041] (2) Dissolve the uniformly mixed lead drug in a 1:1 mixed solution of ethanol and ether. Mix with 15 to 20 ml of solvent per 100 g of lead agent;

[0042] (3) Feeding: Distribute the semi-fluid of lead agent dissolved in organic solvent evenly on the lead paper by spraying, and control the thickness of the sprayed semi-fluid to be about 0.2 mm;

[0043] (4) Forming: the lead paper coated with lead medicament semifluid is made into a lead to be dried by a lead machine;

[0044] (5) Drying: Place the lead wire made by the lead wire machine in a naturally cool and ventilated place to dry to obtain the finished lead wire.

Embodiment 2

[0046] The preparation process of medium-speed leads is as follows:

[0047] (1) 100 mesh (average nitrogen content 11.8%) nitrocellulose 50%, ammonium perchlorate 25%, 100 mesh titanium powder 20% and 100 mesh copper oxide 5% are fully mixed and sieved, and the particle size is too large removal of

[0048] (2) Dissolve the uniformly mixed lead agent in acetone. Mix with 15 to 20 ml of acetone per 100 g of lead wire;

[0049] (3) Feeding: Distribute the semi-fluid of lead agent dissolved in organic solvent evenly on the lead paper by spraying, and control the thickness of the sprayed semi-fluid to be about 0.2 mm;

[0050] (4) Forming: the lead paper coated with lead medicament semifluid is made into a lead to be dried by a lead machine;

[0051] (5) Drying: Place the lead wire made by the lead wire machine in a naturally cool and ventilated place to dry to obtain the finished lead wire.

Abstract

A micro-smoke lead formula comprises the components in percentage by mass: 20%-80% of smokeless gunpowder, 10%-40% of an oxidizing agent, 0%-40% of metal powder and 0%-40% of inorganic salt. The preparation process of a lead comprises the steps: preparing chemicals of the micro-smoke lead, dissolving the chemicals of the lead into an organic solvent, feeding, forming and airing the lead. Comparedwith the prior art, the smokeless powder based on nitrocellulose is used for replacing black powder in a lead formula, so that the problem of environmental pollution is solved, or single and double base powder in the lead formula is replaced, and the problems that the performance of the single and double base powder is uncontrollable and the supply amount of the single and double base powder is limited are solved. Meanwhile, the lead formula is composed of smokeless gunpowder, an oxidizing agent, metal powder and inorganic salt, and smoke generated by combustion is reduced to the maximum extent. Besides, the preparation process for producing the lead by the wet mixing method provided by the invention not only meets the characteristic requirement of lead combustion, but also solves a plurality of defects of lead production by a dry mixing method.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers, in particular to a formulation of a micro-smoke lead wire and a preparation process thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, all kinds of smokeless and smokeless fireworks products have gradually been welcomed by the market. It is the main substance that produces pollutants after fireworks are set off, while the pollutants produced by the burning of fuses in fireworks are ignored. Especially after the main pollution sources such as propellant and bud-opening drug in fireworks are replaced by environmentally friendly smokeless or smokeless products, the problem of polluting smoke generated after the fuse is burned becomes more prominent. [0003] Aiming at the pollution problem of the lead wire, a smokeless and fast lead wire agent for fireworks and firecrackers is designed in the patent with...
