Technical field
The present invention relates to a kind of blasting fuse of high-safety firecracker; Be specially adapted to the firing line of firecrackers firing line or engineering explosion explosive.
Background technology
In the firecrackers firing line or the making of engineering explosion explosive firing line of transmission, all be to adopt Potcrate as oxygenant, Potcrate is because of its oxygen level height, decomposition temperature is low, relative price is low, after combustiblematerials mixes, blast performance is good, but because poor stability, fusing point is low, and mix the back susceptibility with other combustiblematerialss high, accidentally, careless manipulation and cause the burning and explosion hazard, to bring about great losses to the country and people, so State Council's invention regulation in 2002 forbids to use Potcrate preparation fireworks and firecrackers, so the technician of manufacturer begins to develop safety firing cable, some producers begin to adopt potassium perchlorate to replace Potcrate, but all undesirable because of effect, and can't reduce cost, implement as yet.Simultaneously, the making great majority of firing line adopt the paper packaging medicine to carry out hand rubbing firing line or machine-processed firing line, its defective is: because complex production process and complexity and its elasticity differ, cause lead-in wire in the firing line to wrap up in the medicinal powder maldistribution of bag easily, humidity resistance is poor in addition, causes the burst time different in size, and in friction process also idol spontaneous phenomenon arranged, so poor safety performance, the production cost height, efficient is low.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of preparation technology simply, not chloracid potassium, not sulfur-bearing, do not contain composition such as wooden carbon, adopt the blasting fuse of high-safety firecracker of yarn direct impregnation blast medicine.
Technical scheme of the present invention: the preparation method of the firing line of a kind of safety firecracker or engineering explosion 4 prescribe medicines is characterized in that it is that yarn is made firing line as carrier impregnation following raw materials according medicine with by following step:
The weight proportion of each material medicine is:
Potassium perchlorate 50～70%, to benzene dipotassium potassium hydrogen phthalate 3～10%, ammonium dichromate 5～20%,
Polyvinyl alcohol 5～10%, non-blushing thinner 5～8%, charcoal 3～15%, sulphur 1～15%,
Above each component percentage composition sum is 100%;
Each step is:
(1) by above-mentioned weight proportion, with potassium perchlorate, benzene dipotassium potassium hydrogen phthalate, ammonium dichromate, charcoal, sulphur and polyvinyl alcohol are placed in the container, add water in 1: 1 ratio and stirred 3～10 minutes, it is soluble in water to make it medicine, mixes non-blushing thinner again and stirs and get final product; Its non-blushing thinner adopts conventional non-blushing thinner.
(2) yarn is placed in the container flood, promptly yarn enters and makes it yarn in the pharmaceutical liquid of container and stick slowly to extract out behind the medicine to send into and dry in the drying unit;
