Abstract

The invention relates to an aqueous concrete seal hardener and a preparation method thereof in the technical field of building materials. The aqueous concrete seal hardener comprises the following ingredients by mass percentage: 30-40 percent of silicon sol, 0.25-3.0 percent of catalyst, 0.1-0.5 percent of surface active agent, 1-5 percent of potassium methyl silicate and 53.0-66.75 percent of deionized water. In the invention, the aqueous concrete seal hardener can be directly sprayed on the surface of the concrete for construction without pollution; the aqueous concrete seal hardener has strong abrasive resistance, the hardness of the concrete is greatly improved, and the aqueous concrete seal hardener has the characteristics of high sealing property, strong water repellency and dust-proofing performance, hydrolysis is carried out by potassium methyl silicate in the hardener on the surface of the concrete and inside the concrete after permeation, so as to form a membrane with hydrophobic nature and realize the water-repellency and dust-proofing performance; the action of the aqueous concrete seal hardener is durable, and the surface of the concrete has waxing-like luster after the concrete is used for a long time.

Description

technical field [0001] The invention relates to a material and a preparation method in the technical field of construction engineering, in particular to a water-based concrete sealing hardener and a preparation method thereof. Background technique [0002] As a bulk and widely used building material, concrete plays a huge role in modern construction projects. However, due to some inherent defects and deficiencies in the use of ordinary concrete as a floor and pavement material, it is usually easy to dust, poor wear resistance, easy to oil and other phenomena that affect its effect. In order to avoid these phenomena, people do not directly use ordinary concrete as a floor material, or pour a layer of epoxy resin on the concrete surface as a floor material, which increases the construction cost on the one hand, and the later maintenance cost is also relatively high. high. Therefore, in recent years, some cement floor hardeners have appeared on the market. By spraying the cu...
