High-flame-retardant and high-rate plugging foam material and preparation method thereof

Abstract

The invention relates to a high-flame-retardant and high-rate plugging foam material and a preparation method thereof, belonging to the field of novel materials. The high-flame-retardant and high-rateplugging foam material is mainly used at the operation positions, which need to be filled and sealed, of buildings, bridges, mining, dams, and the like. The plugging material obtained by the method prolongs the rise time while guaranteeing a higher expansion rate, and solves the problems that the material in the prior art is early in rising in a plugging process and rapid in reaction speed, so that the operable time is short, the sealing effect is poor, and more hidden problems are caused. The foam material obtained by adopting reasonable raw materials and a reasonable proportion has the characteristics of being slow in initial reaction, strong in operability, good in dimensional stability, high in expansion rate and good in filling and sealing properties, and not shrinking; the materialis prepared by compounding a variety of flame retardants, so that the flame retardant performance is greatly improved, and the safety of construction is guaranteed.

Description

technical field [0001] The invention belongs to the field of new materials for filling and sealing, and in particular relates to a high-flame-resistance and high-magnification plugging foaming material and a preparation method thereof. This material is mainly used in buildings, bridges, mining, dams and other places that need to be filled and sealed. Background technique [0002] In coal mine gas control: gas drainage, parameter testing, coal seam water injection, coal seam anti-reflection and other aspects require drilling technology, and the sealing effect of drilling directly affects the function of drilling, so a better sealing effect is required Drill hole sealing material. [0003] Organic materials are currently one of the commonly used materials for coal mine drilling sealing. The disadvantages at this stage are: (1) The reaction time is relatively fast. Not good, the outside air is easy to enter the gas drainage borehole through the crack channel of the loose circ...

Problems solved by technology

[0003] Organic materials are currently one of the commonly used materials for coal mine drilling sealing. The disadvantages at this stage are: (1) The reaction time is relatively fast. Not good, the outside air is easy to enter the gas drainage borehole through the crack channel of the loose circle around the hole under the action of negative pressure of drainage; (2) The material is highly sensitive to temperature, and its performance is easily affected by the ambient temperature. Poor; (3) The bonding performance of the material is not good, and there is shrinkage phenomenon, resulting in gaps, resulting in sealing failure; (3) The flame retardant performance is generally not high
