The second aspect of the present application provides a method for preparing a high-strength durable grouting material, comprising the steps of:
(1) Placing a propylene compound into a reaction container, adding an oxidant, a high molecular emulsion, a silane compound and water into the reaction container, and fully stirring the mixture at the stirring temperature of 25-30 ℃ for 5-6 hours to prepare a mixture for later use;
(2) And (3) adding a cross-linking agent, an initiator, a bridging agent and an inorganic compound into the mixture obtained in the step (1), and fully stirring and mixing to obtain the high-strength durable grouting material.
Advantageous effects
(1) The application prepares the grouting material with high strength and durability by mixing the propylene compound, the oxidant, the high molecular emulsion, the silane compound, the water, the cross-linking agent, the initiator, the bridging agent and the inorganic compound, and has higher bonding strength, compression tensile strength, impact strength and excellent waterproof performance.
(2) The application can improve the bonding strength, compression tensile strength and impact strength of the prepared grouting material with high strength and durability by adding the propylene compound, and has better waterproof performance, especially the propylene compound is compounded of acrylamide, acrylic acid salt, pentaerythritol tetraacrylate and ethylene glycol dimethacrylate, and the mass ratio is 0.4-0.7:0.3-0.6:0.3-0.5:0.6 to 0.8, wherein the acrylic acid salt is the compound of calcium acrylate, magnesium acrylate and sodium acrylate, and the mass ratio is 2 to 3:3-4:0.5-1, the prepared grouting material has higher bonding strength, compressive tensile strength, impact strength and excellent waterproof performance. The reason is probably that pentaerythritol tetraacrylate is of a high cross-linking density structure and contains a plurality of branched chains, ethylene glycol dimethacrylate is of a long-chain structure and contains branched chains, acrylamide is of an organic small molecule short-chain structure, after the pentaerythritol tetraacrylate and the ethylene glycol dimethacrylate are mixed, the organic molecule short chain of the acrylamide can be fully stretched in a dense cross-linking network formed by the pentaerythritol tetraacrylate and the ethylene glycol dimethacrylate, and the linear chain, the branched chains and the high cross-linking density molecular structure can form a better space position effect, so that calcium acrylate, magnesium acrylate and sodium acrylate are uniformly dispersed in a mixed solution, and polar groups in the calcium acrylate, the magnesium acrylate and the sodium acrylate have stronger hydrogen bonds and intermolecular forces between calcium ions and silicon ions in grouting materials, and a bridging agent with a branched chain structure: the mass ratio of the isobutyl triethoxysilane to the vinyl tri (beta-methoxyethoxy) silane is 0.5-0.7: under the synergistic effect of 1.2-1.4, inorganic compounds are uniformly dispersed in a dense crosslinked network structure formed by propylene compounds and bridging agents, and the organic compounds and the inorganic compounds are tightly connected through the effect of the bridging agents, so that the inorganic compounds are tightly bound in the dense crosslinked network structure, further, the pores of grouting materials are thinned, the grouting materials have a dense structure, the linear chain, branched chain and high-crosslinking density molecular structure and the bridging agents are mutually crosslinked, strong intermolecular acting force exists between molecules at a very near distance, the prepared grouting materials have strong cohesive force, the bonding strength, the compression tensile strength and the impact strength are further improved, and water molecules among the linear chain, branched chain and high-crosslinking density molecular structure are mechanically separated from each other and are not mutually communicated to form closed pores, so that the water molecules in the grouting materials are effectively discharged, capillary pores on the surfaces of the grouting materials are blocked, and water seepage channels are blocked. In addition, the inventor discovers that when the functional monomer modified styrene-acrylic emulsion obtained by emulsion copolymerization of styrene and acrylate monomers is added, the cohesive strength of the grouting material can be further increased, the active functional groups contained in the grouting material can interact with organic functional groups in the propylene compound, the stress concentration phenomenon between the propylene compound and the inorganic compound is relieved, and the cracking of the material caused by the occurrence of material cracks in the grouting material is prevented.
(3) The application is prepared by placing the propylene compound in a reaction vessel, adding the oxidant, the high molecular emulsion, the silane compound and water into the reaction vessel, fully stirring the mixture, adding the cross-linking agent, the initiator, the bridging agent and the inorganic compound into the reaction vessel, and fully mixing the mixture to obtain the high-strength durable grouting material which has higher bonding strength, compression tensile strength, impact strength and excellent waterproof performance.
