Abstract

The invention relates to the field of building materials and aims to provide a preparation method of a nano-sol type colored sealing hardener. The preparation method comprises the following steps: half dosages of ethanol and distilled water are taken respectively and stirred uniformly, then a tin tetrachloride solution is added, an ammonia water solution is added dropwise, silica sol is added, andpH of the solution is regulated to 8-12; the solution is stirred uniformly at 25-40 DEG C; the remaining dosages of ethanol and the distilled water are uniformly stirred, then alumina sol, a silane coupling agent and inorganic toner are added to the mixed solution, and the mixed solution is stirred at 25-40 DEG C; the mixed solutions are mixed, rigid nanoparticles are added with stirring, and then a surfactant is added dropwise; ultrasonic processing is performed after stirring, a stirring reaction is performed at 20-80 DEG C, and the obtained product is the nano-sol type colored sealing hardener. The preparation process is simple, the product integrating concreted hardening and coloring is obtained, and the product can be applied to concrete surface directly in a large area in a roll coating or spray coating manner for construction; a reaction process is easy to control, reaction conditions are mild, VOCs (volatile organic compounds) are avoided in the reaction, environmental pollution is avoided, raw materials are simple, and cost is low.

Description

technical field [0001] The invention belongs to the field of building materials, and specifically relates to a preparation method of a nano-sol type color sealing hardener. Background technique [0002] Concrete is the most widely used man-made building material, and is widely used in various structural projects; however, due to the limitations of the concrete material itself and the construction level, many infrastructures, industrial plant floors, etc. have long been damaged, and the surface has potholes, weathering, Dust, sand, and peeling phenomena lead to poor wear resistance and short service life. They can no longer adapt to the needs of modern production environments and are in urgent need of renovation; Cover a layer of epoxy floor paint, etc.; but the above-mentioned solutions are too cost-effective, and the places of use are limited. For example, laying ceramic tiles or floor tiles, in addition to high labor and material costs, more importantly, the place of use i...
