Abstract

The invention belongs to the technical field of composite materials, and in particular relates to a mine-used airtight fire-proof composite material and a preparation method thereof. Using polyvinyl acetate emulsion, polyacrylate emulsion, polychloroprene emulsion, etc. as base materials, silicate cement, aluminate cement, calcium carbonate, saturated superabsorbent resin and other powders as additives, The prepared composite material has good flexibility, resilience, flame retardancy and antistatic property. Due to the existence of saturated superabsorbent resin, the material has a high water content, which not only has the characteristics of mine sealing, but also has the function of preventing and extinguishing fire. It can make up for the defects such as cement slurry sealing is easy to crack and polyurethane spray sealing material has high reaction temperature and low safety. The raw material of the composite material is easy to obtain, the preparation method is simple, and the construction method is simple, which can replace the original airtight material, and has a good effect of mine airtightness and fire prevention.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a mine-used airtight fire-proof composite material and a preparation method thereof. Background technique [0002] During the excavation process of the new roadway in the coal mine, because the rock is squeezed, damaged or weathered by the machinery and equipment, it is relatively easy to cause falling rocks to hurt people. In addition, there are a large amount of carbon monoxide and gas in the cracks of rocks and coal bodies, and the leakage of these gases will cause a greater threat to the lives of workers in underground construction. Therefore, airtight treatment will be carried out on the surface of the roadway, one is to prevent falling rocks from causing personal injury; the other is to prevent the leakage of gas and carbon monoxide, which threatens the safety of workers. [0003] The traditional sealing methods are cement slurry spraying and sprayi...
