Summary of the invention
The object of the present invention is to provide a kind of preparation method who loads in mixture the porous particulated ammonium oil explosive of car for fixed charge method earth station and mobile on-site.
The technical solution that realizes the object of the invention is:
A kind of porous particulated ammonium oil explosive, composed of the following components by mass percentage: ammonium nitrate 93%-95%, compound diesel 5%-7%; Compound diesel is made up of diesel oil 92%-96% and octadecane amine hydrochlorate 4%-8% by mass percentage.
The preparation method of porous particulated ammonium oil explosive adopts the temperature-sensitive hot-mixing preparation method, may further comprise the steps:
(1) diesel oil and octadecane amine hydrochlorate are joined in the reactor, be heated to 65 ℃-85 ℃ and react and obtain compound diesel;
(2) ammonium nitrate is put into oil bath or steam-heated device internal heating to 65 ℃-85 ℃, added compound diesel again and mix, temperature is controlled at 65 ℃-85 ℃, mixes 10-30 min and obtains porous particulated ammonium oil explosive.
Wherein, hybrid mode adopts interruption to mix or mix continuously in the step (2); Wherein mix the continuous mixing of adopting the charging of ammonium nitrate continuous and quantitative, the spraying of compound diesel continuous and quantitative continuously.
Porous particulated ammonium oil explosive is mainly used in the porous particulated ammonium oil explosive that fixed charge method earth station and mobile on-site load in mixture car and manufactures, the porous particulated ammonium oil explosive production of the industrial explosive manufacturing enterprise that also can be used for fixing a point.
It is the combination of three kinds of technological approaches that temperature-sensitive heat is mixed technology: the one, and the heating ammonium nitrate makes it recover the former minute aperture that pre-exists; The 2nd, adopt the compound diesel that contains tensio-active agent; The 3rd, 50 ℃-90 ℃ middle high temperature of ammonium nitrate and compound diesel mixes, and is conducive to improve homogeneity and the detonation sensitivity of mixing.Adopting of these three kinds of technological approaches effectively improved sensitivity, blast performance and the blasting effect of porous particulated ammonium oil explosive.
The present invention compared with prior art, its remarkable advantage: (1) adopts the temperature-sensitive hot-mixing preparation method with the present invention, the porous particulated ammonium oil explosive that obtains has Sensitivity to Primary Explosion, detonation sensitivity, blast performance, blasting effect raising, the advantage that the toxic gas content that blast back produces reduces has been improved quality and the usefulness of porous particulated ammonium oil explosive effectively; (2) adopt temperature-sensitive heat to mix the porous particulated ammonium oil explosive that method prepares, blast performance improves 20%-30% than the blast performance of the porous particulated ammonium oil explosive for preparing with normal temperature, and blasting effect improves 30%-50%; (3) temperature-sensitive of the present invention heat is mixed production technology and is mainly used in the porous particulated ammonium oil explosive that fixed charge method earth station and mobile on-site load in mixture car and manufactures; And fixed charge method earth station and mobile on-site to load in mixture that the porous particulated ammonium oil explosive of car manufactures be the main developing direction of domestic and international powder industrial explosive, therefore have broad application prospects and economic benefit.
