Abstract
The invention discloses a sulfur-free environment-friendly gun propellant which comprises the following components in parts by weight: 65 parts of potassium acid phthalate, 15 parts of hemp stem carbon powder, 10 parts of an epoxy resin, 2 parts of graphite powder and 5 parts of lime. The gun propellant manufactured according to the formula is applied to display shells, potted flowers, colored bead barrels, display shell rocket propulsion powder and the like. The sulfur-free environment-friendly gun propellant is excellent in safety performance indexes, the friction sensitivity and percussion sensitivity degree are zero, and the potential safety hazards are eliminated; according to the formula, the sulfur component is completely eliminated, so that pollution of sulfur dioxide and sulfides on the environment is eliminated during firework display; and moreover, the gun propellant does not contain forbidden materials; and the environmental protective performance is greatly improved.
Description
Technical field
The present invention relates to a kind of fireworks propelling charge.
Background technology
The current whole nation and even whole world fireworks industry are all to use black powder (military project nitre) to do firework launching in a large number medicinal, black powder is filled a prescription: saltpetre 75% sulphur 10% hemp stalk carbon 15%, although black powder has ignition characteristic well, black powder combustion fumes is large and release sulfurous gas and sulphide staining environment.And black powder is too responsive, mechanical sensitivity is high, is a kind of easily explosion caused breakneck firework gunpowder.Be unfavorable for transport, storage and use, causing fireworks industry and black powder manufacturing enterprise often to occur that serious accident causes personal injury and property damage.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is, provide a kind of environmental protection, safety, without sulphur fireworks launch medicine.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of without sulphur environmental protection propelling charge, it is characterized in that, this propelling charge is made up of the component of following portions by weight ratio: Potassium Hydrogen Phthalate 65 parts, waste of flax carbon dust 15 parts, epoxy resin 10 parts, Graphite Powder 99 2 parts, 5 parts, lime.
Mix by general method, granulation, dry.
Beneficial effect of the present invention is, according to the present invention fill a prescription make propelling charge there is following obvious advantage:
1, described without sulphur environmental protection propelling charge, be suitable for display shell, potted flower, coloured pearl drum, fireworks rocket promotion medicine etc.
2, safe performance indexes is excellent, and friction sensitivity and impact sensitivity are all zero, have stopped potential safety hazard;
3, formula of medicine of the present invention is got rid of sulphur composition completely and is made to eliminate during firework display sulfurous gas and sulfide to the pollution of environment; Not containing forbidding goods and materials (as plumbous hexachlorobenzene, arsenic compound, mercury compound etc.); Environmental-protecting performance improves greatly.
Below will the present invention will be further described by embodiment.
Specific embodiment
Describedly to form without the component of sulphur environmental protection propelling charge by following portions by weight ratio: Potassium Hydrogen Phthalate 65 parts, waste of flax carbon dust 15 parts, epoxy resin 10 parts, Graphite Powder 99 2 parts, 5 parts, lime, mixes by general method, damping granulation, dry.Obtain.
In order to verify product performance, carried out experimental verification to propelling charge product sample obtained in above-described embodiment, detect through ' national fireworks and firecrackers product safety Quality Supervision and Inspection Center ', make survey report, concrete data see table:
| Sequence number | Interventions Requested | Measure unit | Measured result |
| 1 | Friction sensitivity | ％ | 0 (pivot angle 70 °, hydraulic pressure 1.25MPa) |
| 2 | Impact sensitivity | ％ | 0 |
| 3 | Rate of moisture absorption | ％ | 1.48 |
| 4 | Kindling temperature | ℃ | 380.3 |
| 5 | Heat-resistant quality | / | Without combustion explosion phenomenon |
| 6 | Oxymuriate is qualitative | / | Do not detect |
| 7 | Sulphur is qualitative | / | Do not detect |
| 8 | Arsenic is qualitative | / | Do not detect |
| 9 | Plumbous qualitative | / | Do not detect |
