Bi-component polyurea grouting material and preparation method thereof

The invention belongs to the technical field of polyurea grouting materials, and particularly relates to a two-component polyurea grouting material and a preparation method thereof. The component A is prepared from the following raw materials in parts by weight: 78.9 to 84.8 parts of polyether polyol; 15.1 to 20.9 parts of isocyanate; 0.1 to 0.2 part of a stability auxiliary agent; the component B is prepared from the following raw materials in parts by weight: 5.1-6 parts of a curing agent; 48.3 to 54.5 parts of a solid filler; 0.1 to 0.2 part of pigment; 35 to 40 parts of liquid filler; 0.3 to 0.7 part of a wetting dispersant; 0.1 to 0.2 part of a catalyst; 0.5 to 1 part of an anti-settling auxiliary agent; and 3-5 parts of an inorganic chemical defoaming agent. The double-component polyurea grouting material is a dense elastomer after being cured, the defects of a polyurethane grouting material can be effectively overcome, and the leaking stoppage effect is improved. 本发明属于聚脲注浆材料技术领域，具体涉及双组分聚脲注浆材料及其制备方法。所述的
