Dying seal hardener for concrete

Abstract

The invention relates to the technical field of building materials and aims at providing a dying seal hardener for concrete. The dying seal hardener is prepared by mixing the raw materials in percentage by mass: 25-65% of pseudo-boehmite sol, 4-10% of an acrylic resin emulsion, 0.1-1% of a surfactant, 3-8% of a silane coupling agent, 1-5% of nano rigid particles, 1-6% of an inorganic pigment, 6-11% of ethyl alcohol and the balance of distilled water, wherein the nano rigid particles are one or a combination of SiC, BC4, C3N4, Fe3O4 or TiO2. According to the dying seal hardener, the apparent color and luster of the concrete are changed to reach visual aesthetic feeling; the problem of diverse requirements of different populations on the terrace is solved. The product is a water-based material, construction is simple and convenient, the dying seal hardener can be directly rolled on large area or sprayed on the surface of the concrete for construction; the treated concrete surface has the characteristics of high hardness, high abrasive resistance and high glossiness; the dying seal hardener is simple in preparation process and especially suitable for massive industrial production; the reaction process is easy to control; and the reaction conditions are mild.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a dyed seal hardener for concrete. 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 is limited. Generally, it can only be us...

Problems solved by technology

As people's demand for ground diversification increases, they begin to pursue durable and beautiful products, especially the apparent color of concrete. However, none of the above-mentioned patents can improve the basic performance of concrete and change its appearance. Appearance color, so the choice of application is small
