Embodiment 1

[0012] Embodiment 1 is composed of the following components by weight percentage, polyacrylamide 1.5%, urea 15%, sodium nitrate 58.5% and water 25%.

[0013] Its production process includes: raw material screening, urea and water dissolution, polyacrylamide and sodium nitrate mixing, mixing and stirring processes.

[0014] Process description

[0015] 1 Raw material screening, polyacrylamide, urea and sodium nitrate are all industrial products;

[0016] 2 Dissolve urea and water, take urea and water according to the ratio and put them in a stirring container and stir until completely dissolved;

[0017] 3 mix polyacrylamide and sodium nitrate, take polyacrylamide and sodium nitrate according to the proportion and mix evenly;

[0018] 4 Mixing, process 2 and 3 are mixed according to the proportion;

[0019] 5 Stir until evenly mixed.

[0020] The porous granular ammonium oil explosive binder is suitable for on-site mixing and on-site use.

Embodiment 2

[0021] The second embodiment is composed of the following components by weight percentage, polyacrylamide 2%, ethylene glycol 10%, urea 10%, sodium nitrate 48% and water 30%.

[0022] Its production process includes: raw material screening, urea and water dissolution, polyacrylamide and ethylene glycol mixing, mixing, and stirring processes.

[0023] Process Description

[0024] 1 Raw material screening, ethylene glycol adopts industrial products, and the rest are the same as Example 1

[0025] 2 urea is dissolved in water, same as Example 1;

[0026] 3 Polyacrylamide and ethylene glycol are mixed evenly, and the rest are the same as Example 1;

[0027] 4 mixing, adding steps 2, 3 and sodium nitrate in proportion;

[0028] 5 Stir, same as Example 1

[0029] The porous granular ammonium oil explosive binder is suitable for mixing porous granular ammonium oil explosives below medium hard rock.

Embodiment 3

[0030] The third embodiment is composed of the following components by weight percentage, polyacrylamide 4%, ethylene glycol 15%, urea 10%, sodium nitrate 41%, aluminum powder 10% and water 20%.

[0031] The production process is the same as Example 2 except that 41% of sodium nitrate and 10% of aluminum powder are added in sequence.

[0032] The porous granular ammonium oil explosive binder is suitable for mixing porous granular ammonium oil explosives above medium hard rock.

[0033] Instructions for use: The adhesive can be directly mixed with porous granular ammonium oil explosives, and the proportion is: porous granular ammonium oil explosives 85-95%, binder 5-15%. It can also be mixed and used on site, and its proportion is as follows: 80-90% of porous granular ammonium nitrate, 3-6% of light diesel oil and 5-15% of binder. Light diesel oil adopts No. 0, No. 10, No. -10, No. -20 or No. -35.

Abstract

The invention belongs to a porous granular ammonium oil explosive adhesive which is characterized by comprising the following components in percentage by weight: 1.5 to 4 percent of polyacrylamide, 0 to 20 percent of glycol, 10 to 20 percent of urea, 40 to 70 percent of sodium nitrate, 0 to 20 percent of aluminum powder and 10 to 30 percent of water. A method for preparing the porous granular ammonium oil explosive adhesive comprises the following steps of: sieving raw materials, dissolving the urea in the water, dispersing the polyacrylamide and the glycol, mixing, and stirring. In the adhesive, ordinary chemicals are used as the raw materials, dust, toxicity and the pollution of waste water, waste gas and industrial residues are avoided in the production and use process, so the process is simple, investment is small, energy is saved, production cost is low and agglomeration is avoided, and the prepared porous granular ammonium oil explosive does not block the pipe and is not returned and few explosive drops during underground mechanical wind pressure charging, and the explosive has the characteristics of long storage period, namely over six months and environment friendliness, reaches the using standard of the explosive in the prior art and is particularly suitable for operation modes used in mixing sites of mines.

Description

technical field [0001] The invention relates to an explosive binder, which is a porous granular ammonium oil explosive binder used in mines. Background technique [0002] According to the requirements of the Ministry of Metallurgy (79) Yekuang Zongzi No. 48 document, in order to solve the problem of returning the charge of deep-hole pneumatic machinery in underground mines and improve the working conditions of blasting operations, Changsha Mining Research Institute and Hebei Yunshan Chemical Group Co., Ltd. Cixian Anshun Branch of the company (formerly Cixian 219 Factory) has jointly developed a viscous explosive agent after more than two years of hard work. It is made of polyacrylamide, TNT (TNT), ammonium nitrate, sodium dinitrotoluenesulfonate and water or methylamine nitrate diluent, through raw material screening, ammonium nitrate, sodium dinitrotoluene sulfonate and TNT pulverization, mixing, stirring process, with the viscous explosive, porous granular ammonium nitrat...
