The high mechanical strength, the high expansion ratio and the reaction controllability are key factors of whether the polyurethane foaming material can be used for rush repair and construction. However, conventional polyurethane foam materials are difficult to meet the above objective, for the reason: firstly, the common polyurethane foaming material is difficult to solve the influence of environmental humidity on the foaming process, and the volume and mechanical properties of the obtained foam are difficult to control; 2. the maintenance time of the polyurethane foaming material is generally shortened by increasing the dosage of the catalyst, which leads to the great shortening of the operational time of the material and difficulty in normal use; 3. and when the reaction time and operability are met, the mechanical strength of the common polyurethane foaming grouting material is low, and the repairing requirement is difficult to meet. Therefore, the existing polyurethane foaming material is difficult to realize the requirements of quick, convenient and high-strength rush repair and rush construction.

(3) According to the invention, the tertiary amine catalyst and the organic metal catalyst are fully utilized to regulate and control the reaction speed of polyurethane foam gel and the foaming reaction speed, so that the material is foamed normally, and the defects of foam collapse, top crack, shrinkage and the like are avoided; and the foaming time is controlled to be 20-40 s, and the foaming is completed within a few minutes.
(4) The invention adopts the competitive foaming technology, and the expansion ratio and the foam physical property are regulated by introducing competitive reactants, so as to realize the controllable expansion of the material; in addition, the cross-linking type reinforcing agent is introduced to form an interpenetrating network structure, and the cross-linking type reinforcing agent is cooperated with the inorganic reinforcing agent, so that the mechanical property of the material is greatly improved.
