Problems solved by technology

However, during the mixing process of material A and material B, due to the characteristics of the foam being easy to burst, part of the foam burst during the synthesis process, and the early foam burst will cause the final fire extinguishing material to have a higher density; the later foam burst will easily form pores In order to achieve the target density, we will choose to increase the amount of foaming agent added, but when the proportion of foaming agent added is high, the bursting foam will increase the fire-proofing effect on the one hand. The liquid content of the material will prolong the curing time of the material; on the other hand, it will reduce the addition ratio of solid materials such as cement and fly ash, which will affect the compressive strength of the material

Abstract

The invention relates to an inorganic foam fire preventing and extinguishing material and a preparation method and application thereof, the inorganic foam fire preventing and extinguishing material comprises a component A, a component B and a component C. The component A comprises cement, fly ash, an anionic surfactant and water; the component B comprises a foaming agent, a thickening agent, a foam stabilizer and water; the component C comprises an accelerator, a water reducing agent and water; the mass ratio of the component A to the component B to the component C is (10-50): (0.1-4): (1-5). The raw materials are prepared into the component A, the component B and the component C which are stored independently, and then the three components are mixed to prepare the fire preventing and extinguishing material. The invention further provides a preparation method and application of the inorganic foam fire preventing and extinguishing material, on one hand, the technological process is changed, on the other hand, the formula of the inorganic foam fire preventing and extinguishing material is reasonably constructed, the breaking degree of foam in the mixing process is reduced, and the material high in compressive strength and good in leaking stoppage fire preventing and extinguishing effect is prepared.

Description

technical field [0001] The invention relates to the field of mine fire prevention and extinguishing, in particular, the invention relates to an inorganic foam fire prevention material and its preparation method and application. Background technique [0002] Part of the existing fire extinguishing material is organic foam fire extinguishing material, which will cause certain harm to the environment and staff; the other part is inorganic foam fire extinguishing material, the raw materials of this part of fire extinguishing material are mainly cement, foaming agent, thickener Through foaming and solidification, the anti-fire extinguishing material with certain compressive strength and plugging effect can be obtained. [0003] At present, there are two methods for preparing foam fire extinguishing materials. One is to pre-mix cement, foaming agent, etc., and then add water in proportion, and then foam after mixing; the other method is to mix cement, fly ash, etc. The solid mate...
