Description

technical field [0001] The invention relates to the technical field of grouting materials, in particular to a flame-retardant reinforced polyurethane grouting material and a preparation method thereof. Background technique [0002] The grouting material is selected to achieve a certain engineering purpose, can exist in liquid form, and is convenient to use hydraulic pressure, air pressure or electrochemical principles to inject into the internal space of the corresponding medium, such as cracks, cracks, pores, etc., and has the ability to cement and solidify, so that the medium The general term for a class of engineering materials whose leakage channels are blocked and whose physical properties and mechanical properties are improved. However, the existing grouting materials have a low melting point and produce molten droplets when exposed to fire at a high temperature, which is prone to secondary combustion and has an extremely fast flame propagation speed. Therefore, we pr...
