Abstract

A high-safety colour-light firecracker is composed of sounding element and wrapper. The sound element is covered with the wrapper to get the cartridge granules. All the cartridge granules are linked by fuse, and then wrapped by wrapper bands to obtain firecracker. Its advantages are mechanized job, simple method, high productivity and high safety.

Description

Firecrackers generating colour light and production method thereof

The present invention relates to a kind of firecrackers generating colour light and production method thereof.

Firecrackers of the prior art are powdery pharmaceutical several layers paper bag to be wrapped up in form, used powdery medicine is generally the mixture that Oxidizing and Reducing Agents is formed, this mixture is actually a kind of gunpowder, general the no explosive sound of can only burning after it ignites under nature is difficult to distribute in heat that produces when wrapping up in its burning of back with paper bag and the gas inherent coated papers of moment and squeezes and break coated papers and send explosive sound.By making by hand, it makes trouble to this firecrackers, efficiency is low, and poor stability mostly.

The purpose of this invention is to provide that a kind of making is easier, efficient is higher and security firecrackers generating colour light and production method thereof preferably.

Firecrackers generating colour light of the present invention comprises and rings son and leather, ring son and be graininess, ring sub-periphery and be surrounded by one deck leather formation medicine grain, leather with the sub-weight ratio of sound is: 1: 2～4, wherein, ring son and contain (accounting for the percentage by weight that rings son): 60～70% lead orthoplumbate, 12～18% cupric oxide, 12～18 magnadure, 1～3% phenolic resins, 0.5～1.5% ethanol; Leather contains (percentage by weight that accounts for leather): 50～65% potassium hyperchlorate, 8～15% antimony trisulphide, 10～18% magnadure, 12～20% charcoal, 1～2% phenolic resins, 0.5～1% ethanol.

Its preferred version is, ring son and be made of (accounting for the percentage by weight that rings son) lead orthoplumbate of 66%, 15.5 cupric oxide, 15.5% magnadure, 2% phenolic resins, 1% ethanol, leather is made of (accounting for the percentage by weight of leather) potassium hyperchlorate of 60%, 13% antimony trisulphide, 10% magnadure, 15% charcoal, 1.2% phenolic resins, 0.8% ethanol.

And, being provided with the wrapper bands that bag rings the medicine grain of son and leather formation, medicine grain double team is in strap.

The method of the above-mentioned firecrackers of production provided by the invention may further comprise the steps: one, choose raw material by said ratio; Two, lead orthoplumbate, cupric oxide, phenolic resins, the magnadure of choosing mixed and sieve; Three, sieve to such an extent that sound is sub behind the mixture pelleting that previous step is sieved; Four, potassium hyperchlorate, antimony trisulphide, magnadure, charcoal, the phenolic resins of choosing is mixed and sieve; Five, be wrapped in to ring and obtain the medicine grain on the son with the sieve mixture that obtains of previous step, be wrapped in the integument that rings sub-periphery and be leather; Six, the medicine grain is sieved back is dry.

The above-mentioned granulation that rings son is that 2/3rds of the lead orthoplumbate after sieving, cupric oxide, phenolic resins, magnadure mixture put into cylinder, when cylinder rotates, and the mixture spray ethanol of limit in the cylinder, the mixture that the limit adds remainder; Ringing the sub method that goes up the parcel leather is will ring son and put into cylinder, when cylinder rotates, go up spray ethanol towards ringing son earlier, the limit adds the mixture of potassium hyperchlorate, antimony trisulphide, magnadure, charcoal, phenolic resins then, and spray ethanol in limit is until becoming required medicine grain.

With above-mentioned dried medicine grain with the wrapper bands double team firecrackers that become band.

The present invention is owing to adopt technique scheme, loud son in the firecrackers is actually a kind of explosive, its generally blast about 1200 ℃, and leather is a kind of gunpowder, and it can light after-combustion, and send heat and temperature is risen to make about 1200 ℃ and ring son and ignite, and reach the effect of firecrackers.Medicine grain among the present invention can adopt the mechanization granulation to make, wrapper bands parcel medicine grain also can be finished with packing machine, thereby production efficiency height of the present invention, make simple since ring son will be about 1200 ℃ could quick-fried sound, thereby in manufacture process or aspects such as storage, transportation all safer.

Below in conjunction with embodiment the present invention is further described.

Fig. 1 is the structural representation of firecrackers of the present invention;

Fig. 2 is the A-A cutaway view of Fig. 1.

Comprise referring to Fig. 1, Fig. 2, firecrackers of the present invention and to ring son and leather, ring son and be graininess, it can at high temperature be ignited and send explosive sound, ring sub-periphery and be surrounded by one deck leather formation medicine grain 2, leather is 1: 2～4 (can choose arbitrarily in this proportion) with the weight ratio of ringing son, preferred version is 1: 3, medicine grain 2 can wrap up with wrapper bands 1, as sticking with 1 pair of double-deck strip adhesive tape, medicine grain 2 double teams are between DR tape 1, for ease of ignition powder grain 2, also be folded with between the DR tape 1 and draw core 3, medicine grain 2 is distributed in and draws around the core 3.Constituting the raw material that rings son and leather can choose arbitrarily in above-mentioned given range, table one provides a few assembly ratios that constitute the material composition (accounting for the percentage by weight that rings son) that rings son, table two provides a few assembly ratios of the material composition (accounting for the percentage by weight of leather) that constitutes leather, and the arbitrary assembly ratio in the table one can be produced the medicine grain than combination with arbitrary assembly in the table two.
