Abstract

The invention relates to the technical field of materials, and discloses a composite material and a preparation method thereof, wherein the composite material comprises a component A, a component B and a component C according to a weight ratio of 1:0.7-0.95:0.0001-0.4, the component A contains, by weight, 80-99.2% of an alkaline solution and 0.8-20% of a catalyst, the component B contains, by weight, 80-99% of a polyisocyanate prepolymer and 1-20% of a solubilizing agent, and the component C contains a silicon-aluminum material. The composite material of the present invention integrates the high compressive strength and the low maximum-reaction-temperature.

Description

Technical field [0001] The invention relates to the technical field of materials, in particular to a composite material and a preparation method thereof. Background technique [0002] At present, the materials commonly used in dam foundation pit reinforcement, coal and rock mass reinforcement, anti-seepage plugging, road subgrade load-bearing filling, based on the consideration of safe production, need to have high compressive strength; at the same time, the safety in the material preparation process The problem also requires a low maximum reaction temperature. However, there is currently no composite material that can have both high compressive strength and low maximum reaction temperature. [0003] US3607794A discloses the reaction process of an organic polyisocyanate and an alkali metal silicate solution, explaining the effect of different reaction ratios on the properties of the consolidated body. However, the material obtained by the method disclosed in the patent applicatio...
