Problems solved by technology

[0004] The main technical problem to be solved by the present invention is: the present invention provides a preparation method of a highly wear-resistant concrete seal and cure agent for the problems that the current concrete seal and cure agent has insufficient wear resistance and slow strength improvement. Soluble substances in slag, precipitate and activate silicic acid, use platinum dioxide as a catalyst, catalyze silicate at high temperature, and freeze the formed silicate to destroy the original network structure inside the silicate particles and increase its penetration Then polymerize triglyceride and glucose. At the same time, add lithium sulfate during the reaction process to make the polymer and lithium ions undergo chelation reaction and combine lithium ions. Finally, the treated frozen material, residual liquid and coupling Mixed with isobutyl triethoxysilane and other agents to react, increase the crosslinking density, thereby improving its surface abrasion resistance, and finally obtain a high wear-resistant concrete sealing and curing agent
After use, the high wear-resistant concrete sealing and curing agent prepared by the present invention undergoes condensation reaction rapidly with the metal in the compound state under the catalysis of platinum to form a gel, and at the same time, the surface polymer is combined with the metal in the compound state to further improve the Wear resistance, thus solving the problem of insufficient wear resistance and slow strength improvement of concrete seal curing agent

technical field [0001] The invention relates to a preparation method of a high wear-resistant concrete sealing and curing agent, belonging to the technical field of sealing and curing agents. Background technique [0002] Concrete sealing and curing agent is an active colorless and transparent chemical water-based preparation, which is composed of inorganic substances, chemical active substances and complexes and adopts a unique formula. It is easy to use, non-toxic, and non-flammable. Dust and hard wear. Its working principle is to chemically react with a large amount of hemi-hydrated cement, free lime, and calcium in concrete to form a permanent gel, which can crystallize into a hard and wear-resistant structure inside the treated concrete, thereby obtaining a Dust-free, dense whole. [0003] At present, the inorganic concrete floor hardeners on the market are mainly produced by three types: the first type is a sodium-based salt product mainly composed of sodium silicate...
