Novel coal mine fireproof leaking-stoppage colloid material

Abstract

The invention discloses a novel coal mine fireproof leaking-stoppage colloid material, and belongs to the field of fireproof material. The novel coal mine fireproof leaking-stoppage colloid material is composed of a base material and a gelatinizing agent. Advantages of the novel coal mine fireproof leaking-stoppage colloid material are that gelatinization can be realized by mixing a composite material with water; respective dilution and mixing of sodium silicate powder and other materials are not necessary; a preparation method is extremely simple; and cost is low. The novel coal mine fireproof leaking-stoppage colloid material can be used for chemical adsorption on loose coal, and inhibiting free radical chain reaction in coal and oxygen reaction processes; excellent inhibition effect is achieved; formed colloid slurry possesses certain viscosity, and is capable of realizing leaking stoppage; water retention rate is higher than 86.6%; under mine environment pollution is not caused; and the novel coal mine fireproof leaking-stoppage colloid material possesses excellent market competitive advantages.

Description

technical field [0001] The invention relates to the field of fireproof materials, more specifically, the invention relates to a novel coal mine fireproof and plugging colloidal material. Background technique [0002] Spontaneous fires in coal mines in my country are very serious. According to incomplete statistics, coal losses caused by spontaneous fires in coal mines in my country are as high as 50 to 60 million tons every year. Natural fires accounted for 96.5% of the total number of fires. There are still more than 200 fire areas in key state-owned coal mines, accounting for 44.9% of the total number of coal seam fires, freezing more than 40 million tons of coal, and causing direct and indirect economic losses of more than 5 billion yuan. Spontaneous combustion of coal seams not only produces CO, SO 2 And other harmful gases, and often cause major accidents such as gas explosions, which seriously threaten the lives and health of workers and cause huge resource losses to ...

AI Technical Summary

Problems solved by technology

[0004] 1. A large amount of ammonia gas will be produced during the formation of the gel, which can seriously deteriorate the air quality of the roadway. After the ammonia gas combines with the body fluid or water of the operator, it will form a certain corrosive ammonia water, which will cause the operator's eyes, Alkaline burns occur in the mouth and respiratory organs, endangering the health of workers and affecting the safe production of mines

[0005] 2. Strong corrosiveness

[0006] 3. The process is complicated, water glass needs to be diluted separately, and then mixed with other material aqueous solutions, which is easy to cause waste of materials, troublesome transportation and storage

[0007] 4. The water retention effect is not good. Using calcium hydroxide and other inorganic salt materials is easy to form a large amount of sediment, and the colloid dries up quickly.

[0008] 5. Higher cost

The cost of a single polymer resin material is nearly 10,000 yuan, and it is difficult to promote
