Abstract
The invention belongs to titanium sponge powder-containing high-strength modified ammonium nitrate fuel oil explosive used in engineering blasting and a method for making the same. The ammonium nitrate fuel oil explosive is powdery explosive consisting of powdery ammonium nitrate, wood flour, modified addition agent, a compound oil phase material and titanium sponge powder. The high-strength modified ammonium nitrate fuel oil explosive does not contain high explosives such as TNT, and contains titanium sponge powder; moreover, the explosive has a simple manufacturing method and better explosion properties than ammonium nitrate fuel oil explosive.
Description
Technical field
The present invention relates to a kind of spongy titanium powder high-powered modified ANFO and preparation method thereof that contains.
Background technology
At present, the an-tnt explosive of domestic most of manufacturer production more or less all contains the TNT single chmical compound explosive.Because danger is bigger in TNT production, transportation, the storage process, environmental pollution is serious, and is bigger to the physically and mentally healthy harm of operator, is one of product of China's limit production; Do not overcome above shortcoming though existing expanded ammonium nitrate powder type explosive, modified ammonium nitrate-fuel oil explosive etc. do not contain the explosive of high explosive, had shortcomings such as bulk strength is little, applied being subjected to certain limitation.
Summary of the invention
The purpose of this invention is to provide a kind of spongy titanium powder high-powered modified ANFO and preparation method thereof that contains, need not change existing an-tnt explosive production unit, only add the sponge titanium valve aborning and change production technique and just can improve explosive property.
The present invention is a kind of spongy titanium powder high-powered modified ANFO that contains, and comprises 86～91.99% ammonium nitrate, 2～3% wood powder, 2～4% compound oil phase, 4～6% spongy titanium powder, 0.01～1.0% property-modifying additive.
Another kind of scheme of the present invention is that the property-modifying additive in the such scheme is the mixture of stearylamine and K12.
Another scheme of the present invention is at such scheme, and the blending ratio of described stearylamine and K12 is 1: 2.
Produce the preparation method of a kind of spongy titanium powder high-powered modified ANFO as claimed in claim 1, heavily cut or polish jade with an emery wheel wheel roller and heavily cut or polish jade with an emery wheel pressure nitre dropping into 100～120 ℃ after the ammonium nitrate coarse crushing, rolled 20～30 minutes, add the mixed modification that makes and add agent, rolled again 10～20 minutes, ammonium nitrate fineness 70% is crossed 60 orders, wood powder is pulverized through flue gas drying, compound oil phase is at 90～110 ℃ of melting and heat preservations, then modified ammonium nitrate is ground and mixed 2～4 minutes, add compound oil phase and mixed 18～20 minutes, add wood powder again, spongy titanium powder mixed system 10～16 minutes, at last, the product of the system of mixing is packed down in 45 ℃.
The advantage that the present invention has is:
1, this contains the spongy titanium powder high-powered modified ANFO and does not contain toxicity explosive substance TNT, has eliminated TNT to the harm of HUMAN HEALTH with to the pollution of environment.
2, since the development and use of titanium sponge more and more widely, add the sea titanium valve, the energy of explosive is improved greatly, do not contain the blast performance excellence of high explosive than existing expanded ammonium nitrate powder type explosive, modified ammonium nitrate-fuel oil explosive etc., the sea titanium contacts no sensitization, carcinogenic, aberration inducing phenomenon with human body in addition.Titanium be owing to can stabilize body current, the tight state of the muscle of releiving, and spirit can be loosened, muscle also can loosen ， And gradually and can improve motion function, therefore, helps operator's holistic health.
3, it is simple to add properties-correcting agent, does not contain any susceptibility material, processes safe in utilization.
4, need not to change existing equipment, suitable for producing.
