preparation example Construction

[0043] The present invention also relates to a preparation method of the above-mentioned fire extinguishing colloidal material, comprising: mixing the components uniformly.

[0044] Preferably, the method comprises:

[0045] 1). Mix the calcium salt and water according to the mass ratio of 4:43-49, fully stir for 5min-10min to form a solution, then add the sodium silicate, and fully stir for no less than 10min to obtain a mixture A;

[0046] 2). Mix the coagulant with the remaining amount of water, and stir fully for no less than 10 minutes to obtain mixture B;

[0047] 3). Mixing the mixture A with the mixture B;

[0048] Wherein, step 1) and step 2) have no sequence;

[0049] Preferably, the method comprises:

[0050] 1). Mix the calcium salt and water according to the mass ratio of 4:46, fully stir for 5min to 10min to form a solution, then add the sodium silicate, and fully stir for 10min to 15min to obtain mixture A;

[0051] 2). Mix the coagulant with the remaining a...

Embodiment 1

[0064] The anti-fire colloidal material of the present embodiment, the quality of its sodium silicate is 5g, and the quality of limestone is 7g, and the quality of ammonium bicarbonate is 3g, and water 85 parts; When configuring, as figure 1 As shown, limestone and water were mixed according to the mass ratio of 4:43, fully stirred for 5 minutes to form a solution, then the sodium silicate was added, and fully stirred for 10 minutes to obtain mixture A; ammonium bicarbonate was mixed with the remaining water, fully Mixture B was obtained by stirring for 10 minutes; after mixing the two solutions through a tee, the solution was sprayed onto the coal seam with a mud pump, and its performance indicators are shown in Table 1.

Abstract

The invention relates to the field of fire-preventing and fire-extinguishing safety technologies, and specifically relates to a fire-preventing and fire-extinguishing colloid material, as well as a preparation method and an application thereof. The fire-preventing and fire-extinguishing colloid material is prepared from the following raw materials: 4-8 parts of sodium silicate, 4-8 parts of calcium salt, 2-6 parts of coagulant and 80-88 parts of water. The material has the characteristics of being fire-preventing and fire-extinguishing, obvious in cooling effect, convenient to construct, and safe and environment-friendly, and the effective utilization rate of the material can be effectively increased; the material is free from adverse chemical reactions, and harmless to environment and people, and the generation of ammonia gas is reduced; and moreover, the calcium salt has a good inhibition effect on the spontaneous combustion of high-sulfur ores. Correspondingly, the invention furtherprovides a preparation method and an application of the colloid material.

Description

technical field [0001] The invention relates to the field of fire prevention and safety technology, in particular to a fire prevention colloidal material and its preparation method and application. Background technique [0002] Chemically, any substance that can reduce the speed of a chemical reaction is called an inhibitor. The principle of anti-fire extinguishing by chemical inhibitor is to pour the solution or emulsion (resistor) of one or several substances into the coal wall or coal pillar cracks in the goaf and other places prone to spontaneous combustion, and the chemical inhibitor is attached to the surface of the coal. , Isolate oxygen, prevent the oxidation of coal, prolong the coal fire period or prevent coal fire. [0003] Foreign countries have successively studied inorganic inhibitors such as calcium chloride, calcium hydroxide, calcium bicarbonate, and water glass gel, and organic inhibitors such as phenolic resins, epoxy resins, and surfactants. At present,...
