The invention provides an environment-friendly acrylate grouting material, as well as a preparation method and an application thereof. The material mainly comprises the following components in parts by weight: a main agent, namely 100 parts of methacrylic acid-beta-hydroxyethyl ester, a crosslinking agent which includes 5-30 parts of hydrophilic compound containing a diallyl ether functional group, 1-5 parts of initiator and 0.5-3 parts of accelerant, 0-20 parts of an adjuvant, and a solvent, namely 2-1,000 parts of water. The method comprises the following steps: firstly, mixing the main agent, the crosslinking agent, the accelerant, the adjuvant and a part of solvent evenly to form a solution A in use; then dissolving the initiator into a residual solvent to form a solution B; and finally mixing the solution A with the solution B evenly, and solidifying at room temperature. According to the grouting material disclosed by the invention, the technical problem that the existing organic grouting material cannot be grouted once after being mixed with an inorganic grouting material, and the technical problem that the existing grouting material has poor durability, low strength, poor water solubility, low water expansion rate and high toxicity are solved.
