Embodiment 1

[0026] A fire-fighting additive based on construction dregs, its components and content: construction dregs: 90%, lignosulfonate: 4%, acrylamide-acrylic acid copolymer: 2%, sodium carboxymethylcellulose : 4%.

[0027] The preparation steps of the fire prevention and extinguishing aid based on construction dregs are as follows: air-dry the construction dregs first, and then pulverize them; Stir for 3-5 minutes; then sprinkle the pulverized construction dregs and mixed superplasticizer, water-retaining agent and dispersant on the dry mixer, and stir for 8-10 minutes to obtain the fire-fighting aid. agent.

[0028] The method of using the anti-fire extinguishing additive based on construction dregs is as follows: firstly add 30% of the anti-fire extinguishing additive to the fly ash, mix evenly to obtain the fly ash containing the anti-fire extinguishing additive; Auxiliary fly ash and water are added to the mixing box, which contains the weight ratio of fly ash and water of an...

Embodiment 2

[0030] Compared with Example 1, the difference of this embodiment is that the anti-fire extinguishing additive based on construction dregs, its components and content: construction dregs: 75%, polycarboxylate: 8%, polyacrylamide: 3%, sodium carboxymethylcellulose: 14%.

[0031] In the method of using the fire prevention and extinguishing additive based on construction dregs, 20% of the fire prevention and extinguishing additive is firstly added to the fly ash.

Embodiment 3

[0033] Compared with Example 1, the difference of this embodiment is that the anti-fire extinguishing additive based on construction dregs, its components and content: construction dregs: 70%, polycarboxylate: 10%, polyacrylamide: 4%, sodium carboxymethylcellulose: 16%.

[0034] In the using method of the anti-fire extinguishing auxiliary agent based on construction dregs, 18% of the anti-fire extinguishing auxiliary agent is firstly added to the fly ash.

Abstract

The invention provides a fire prevention and extinguishing aid based on construction dregs, including construction dregs, a superplasticizer, a water-retaining agent and a dispersant, wherein each component is: 60%-90% of construction dregs , 4%-15% superplasticizer, 2%-5% water retention agent and 4%-20% dispersant. A new type of anti-fire extinguishing additive that can greatly improve the injectability, slurryability and fire extinguishing performance of fly ash is prepared by using the clay, foaming agent and a small amount of polymer compound in the construction dregs to realize the waste of different industries The synergy and comprehensive utilization of materials can achieve the purpose of energy saving, emission reduction and disaster management; construction waste can be utilized as a resource without further treatment, which solves the problem of construction waste disposal; through compounding with a small amount of functional polymers, it effectively improves The slurrying and grouting efficiency of fly ash greatly reduces the cost of fire prevention and extinguishing.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment and fire protection, in particular to a fire prevention and extinguishing auxiliary agent based on construction dregs. Background technique [0002] Construction slag is a kind of industrial waste produced in the process of building construction, with complex components. With the acceleration of urbanization and the expansion of scale in our country, the amount of construction waste is increasing year by year. The construction waste is piled up on the spot, which not only takes up a lot of land resources, but also causes very serious pollution risks to the soil, surface water and groundwater in the storage area and nearby areas. Therefore, the comprehensive recycling of construction dregs has become an important issue that urgently needs to be studied and solved. [0003] In my country's coal mines, 70% of coal mines have the risk of coal seam spontaneous combustion. According...
