Abstract
The firework exploding and sounding agent without chlorate and perchlorate comprises composite oxidant, inflammable sulfur, easy-to-burn aluminum powder and density regulating agent, and features the composite oxidant comprising potassium nitrate 10-50 wt%, barium nitrate 50-90 wt% and potassium permanganate 0-25 wt%. The firework exploding and sounding agent has also added pH regulating agent boric acid and deactivating agent magnesia or stearic acid. The firework exploding and sounding agent has high heat stability, no decomposition under 75 deg.c and minus 25-35 deg.c for 48 hr, friction sensitivity lower than 60 %, knocking sensitivity lower than 50 %, no burning and explosion in falling test and sympathetic detonation test, high fire approaching performance and no special requirement in firing line, and may be used in type B and type C firework products.
Description
Technical field
The present invention relates to the pyrotechnics detonating agent that uses in a kind of fireworks and firecrackers product.
Background technology
The pyrotechnics detonating agent is generally by oxygenant, combustible agent, density adjusters etc. are composite to form, the oxygenant of existing pyrotechnics detonating agent is generally Potcrate or potassium perchlorate or potassium perchlorate to be mixed with nitrate of baryta, the composite again combustible agent sulphur of going up, flammable aluminium powder, the density adjuster swelling perlite powder, this prescription potential safety hazard is very big, the Potcrate fusing point is lower, only 356 ℃, being subjected to intense impact is explosibility, itself has the effect of impact sensitivity, comparatively responsive to friction, with combustible agent sulphur, antimony sulfide is mixed the back susceptibility to be increased, danger is very big, decomposed easily by sun exposure, generates extremely unsettled potassium chlorite and bibulous Repone K; Potassium chlorite mixes with acids, sulfide and organism, almost spontaneous combustion immediately or self-destruction.So burning or blast often take place in processes such as production, storing, very easily lead to security incident; Potassium perchlorate is also because its susceptibility equally also is the source of security incident.Its fusing point height, it is 610 ℃, be easy to form perchlorate's residue behind the adding detonating agent, environmental protection scholar of the U.S. has delivered the article of " effect of perchlorate in environmental pollution in the fireworks industry " recently, spell out perchlorate and the drinking water source is constituted new threat, its destruction mainly is the Tiroidina role and destroys required hormonal generation in the metabolism, caused the intensive concern in the U.S..
Summary of the invention
The object of the present invention is to provide that a kind of security is good, drug compatibility is good, producing and setting off and to reduce in the process surrounding environment and atmospheric pollution, not chloride hydrochlorate easy to use and the novel pyrotechnics detonating agent of perchlorate.
Detonating agent of the present invention comprises composite oxidant, combustible agent sulphur, inflammable aluminium powder, density adjuster swelling perlite powder, it is characterized in that composite oxidant is made up of following component and weight part: saltpetre 10-50, nitrate of baryta 50-90, potassium permanganate 0-25.
Composite oxidant should be adjusted according to different products with the proportioning of combustible agent;
General composite oxidant: combustible agent=0.7-1.6: 1
In combustible agent, also can add in a certain amount of Chinese fir wood charcoal or the antimony sulfide one or both according to the requirement of some product.
Also be added with acid-base modifier boric acid in addition, deterrent magnesium oxide or stearic acid;
The pH value of this detonating agent is in the 5-9 scope after deliberation, moisture content is less than 1.0%, rate of moisture absorption is less than 2.0%, heat-resistant quality under (75 ± 2) ℃ and subzero 25-35 ℃ condition, 48 hours no decomposing phenomenons, friction sensitivity is less than 60%, impact sensitivity is less than 50%, and product fall down test, gap test all do not fire, and it burns till rate; To category-B firecracker (single product dose 2 gram below) greater than 90%; To c class firecracker (single product dose 0.5 gram below) greater than 85%.Sound level is less than 140 decibels, and starting to exchange fire property is strong, and firing line is not had particular requirement, and this product can be suitable for category-B, the multiple firecracker product of C class and part fireworks display product.
Not chloride hydrochlorate and perchlorate in this detonating agent, also arsenic compound not, mercury compound, lead compound, gallic acid, picric acid, the magnesium powder, phosphorus, the medicine of country such as hexachlorobenzene forbidding, safety performance improves greatly, the safety of medicine performance meets national standard, safety coefficient is higher than the combination formula of oxymuriate or perchlorate, the threat of also having avoided perchlorate that the drinking water source is constituted, to setting off environment and HUMAN HEALTH is favourable, owing to do not contain expensive potassium perchlorate, production technique is simple, raw material sources are extensive, simplified plurality of raw materials, multiple channel, respective procurement, operations such as batching, reduce comprehensive cost, can realize the starting material specialization, intensification is produced.
