Embodiment 1

[0029] Embodiment 1: barium benzoate production process:

[0030] A, take by weight 4.88 kilograms of benzoic acid and 2.61 kilograms of barium nitrate, uniformly mix after crossing 8 to 10 mesh sieves respectively, and can cross 8 mesh sieves to reach uniform requirements after mixing again,

[0031] B. Put the mixed material into a small iron or enamel glass reaction tank (reaction container), without agitator, and the amount of material should not exceed half of the capacity of the container (for small-scale production, the material can be put into 20 to 24 cm In a pressure cooker, it is advisable that the amount of material should not exceed half of its capacity);

[0032] C, 2.2 kilograms of water are put into reaction tank;

[0033] D. Conventionally heat the reaction tank and control the temperature in the tank at 90 to 110°C and the pressure at 0.1 to 0.2kg / cm 2 15 to 20 minutes, then stop heating, and naturally cool the material to 60 to 70°C under normal pressure t...

Embodiment 2

[0037] Embodiment 2: strontium benzoate production process, weigh 4.88 kilograms of benzoic acid, 1.48 kilograms of strontium carbonate, carry out by embodiment 1 technique, and the amount of water added is 1.8 kilograms.

[0038] In the actual production of the passivator of the present invention, the amount of water added can be controlled at 20-24% (percentage by weight).

Abstract

The production process of barium benzoate and strontium benzoate used as chlorate explosive passivator includes the following steps: respectively using (wt%) 50.3612% of benzoic acid and 26.9350% of barium nitrate ( or 59.8039% of benzoic acid and 18.1373% of strontium carbonate) passed through 8-10 mesh sieve, and placing them in reaction container, adding about 22% of water, controlling temp. to 90-110 deg.C, pressure is 0.1-0.2 Kg / sq.cm for 15-20 min., and then cooling to about 60 deg.C, taking out the obtained material, drying to make its water content be 2-3%, pulverizing to pass through 60-80 mesh sieve so as to obtain the invented finished product. It can effectively reduce mechanical sensitivity of explosive, and can ensure its excellent explosive performance.

Description

technical field [0001] The invention relates to the application of barium benzoate and strontium benzoate as chlorate gunpowder passivators. Background technique [0002] In the prior art, chlorate gunpowder (as potassium chlorate) is the main raw material for producing matches, fireworks and firecrackers, and occupies an important position in the regional economy. [0003] Because chlorate propellant has the advantages of strong oxidizing property, good explosive performance, easy ignition, stable chemical and physical properties, etc., especially the mixed pyrotechnic agent with potassium chlorate as oxidant has good flammability, explosive property and color-helping property. , are widely used in civil pyrotechnics industry. However, due to the high mechanical sensitivity of chlorate pyrotechnic agents, potassium chlorate cannot be co-ground with organic matter. When it is mixed with sulfur, phosphorus, organic matter or combustible matter and rubbed or collided, it is v...
