Problems solved by technology

However, the high ground pressure increases the deformation of the roadway, which leads to the cracking of the wall of the ventilation structure, which increases the amount of air leakage and affects the production safety of the mine.
[0003] Although some existing wall materials have good effects, there are certain problems in the process of use: the construction process of rockshou, aeglauni, and Ruimi sealing materials is complex, requiring special equipment, and the cost of QC spraying materials is high and the economic benefits are poor. , In addition, the walls of these materials are not smooth after spraying

Abstract

The invention discloses a high-elasticity flame-retardant two-component wall surface material and a preparation method thereof, wherein a component A prepolymer comprises polyglycerol ether, hydroquinone, toluene diisocyanate, nitrile butadiene rubber and polymethyl propionate, a component B prepolymer comprises a liquid filler, octyl phthalate, 1,4-butanediol, 3,3'-dichloro-4,4'-diaminodiphenylmethane, calcium carbonate, an antistatic agent, an organotin catalyst, diphenylamine and triphosphate, and the component A prepolymer and the component B prepolymer are completely mixed according to aratio of 2:1 to obtain the high-elasticity flame-retardant two-component wall surface material. According to the present invention, the coating has advantages of good compactness, noninflammability, simple construction and adjustable thickness; the component A prepolymer, the component B prepolymer and the novel wall surface material are the non-flammable materials, and can be directly coated ontothe wall; the thickness of the coating can be adjusted, such that the material can be used at mine shaft air doors, dampers, closed gaps and other easy-to-leakage places; and the material has good elasticity and strong tensile strength.

Description

technical field [0001] The invention relates to the technical field of mine ventilation, in particular to a highly elastic flame-retardant two-component wall surface material and a preparation method thereof. Background technique [0002] In order to realize the stability and reliability of the ventilation system, there must be a stable and reliable ventilation structure. However, with the improvement of the degree of mechanization of mine mining and the increase of coal mining depth, the section (roadway) of the construction point of ventilation facilities is required to increase continuously, and the ventilation facilities need to have higher pressure bearing capacity and air leakage prevention capacity. However, the high ground pressure increases the deformation of the roadway, which leads to the cracking of the wall of the ventilation structure, which increases the amount of air leakage and affects the production safety of the mine. [0003] Although some existing wall ...
