Nano-silicon-modified double-component wear-resistant penetration hardener and preparation method thereof

Abstract

The invention relates to the technical field of protection treatment of concrete materials, and aims to provide a nano-silicon-modified double-component wear-resistant penetration hardener and a preparation method thereof. The hardener comprises a component A and a component B, wherein the component A is composed of silicone prepolymer, a wear-resistant modification material, a stabilizer and a solvent; the component B is composed of a catalyst and a solvent; both components adopt alcohol as the solvent. The nano-silicon-modified double-component wear-resistant penetration hardener provided by the invention has a higher hardening speed and a more obvious wear-resistant effect compared with an aqueous silicate penetration hardener, is stored separately in the form of the component A and the component B to provide better storage stability compared with a single-component organosilicon resin penetration hardener so as to better ensure the permeability to the concrete during use, and adopts nano-silicon sol as the wear-resistant modifier to greatly improve the wearing-resistance of concrete treated by the penetration hardener.

Description

technical field [0001] The invention belongs to the technical field of protective treatment of concrete materials, and in particular relates to a nano-silicon modified two-component wear-resistant penetrating hardener and a preparation method thereof. Background technique [0002] With the development of economy and technology, concrete has been widely used in various fields of human activities and has become the cornerstone of social development. However, when ordinary concrete is used as a floor and pavement, there are still problems such as poor wear resistance, easy dusting, and sanding. These problems are determined by the characteristics of concrete itself: during the process from pouring to solidification and hardening of concrete, the coarse aggregate sinks and the cement slurry floats up, resulting in poor wear resistance of the concrete surface; after the hydration reaction, excess water is emitted from the inside, causing The concrete structure has many pores and...
