A kind of two-component nano-sol type liquid curing agent and preparation method thereof

Abstract

The invention relates to the technical field of building materials and aims to provide a two-component nano-sol type liquid hardener and a preparation method thereof. The liquid hardener is composed of A component solution and B component solution; A component solution is made by mixing silicon tetrafluoride solution, silica sol, surfactant and distilled water; Stone, ammonia water, silane coupling agent and distilled water are mixed. The two single-component solutions of the present invention do not undergo internal reactions and can be preserved for a long time. The ingredients used can have an irreversible chemical reaction with concrete, fill and compact the holes, and firmly fill and form an overall structure; the product has a simple preparation process, no pollution to the environment, simple raw materials, low cost, and can be directly rolled or sprayed on a large area To the concrete surface for construction, especially suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of building materials, and specifically relates to a two-component nano-sol type liquid hardener and a preparation method thereof. Background technique [0002] At present, the infrastructure and industrial plants that have been concreted have poor wear resistance and short service life. After long-term use, potholes, weathering, dust, sand, and peeling will appear on the surface; they can no longer meet the needs of modern production environments. In desperate need of a makeover. In order to solve this problem, many scholars have developed a variety of hardeners specially used for concrete floors in recent years, which can greatly increase its service life. [0003] At present, there are two types of ground hardener materials that are used most in the domestic and foreign markets: one is silicate products, such as CN200910055825 and CN201110083155. Lithium silicate, etc.) as the main component, and magnesium fluoro...

Problems solved by technology

[0004] Although these formulas can effectively improve and enhance concrete hardness, wear resistance and other properties, they are all based on a single component to strengthen the hardened ground, and there is no product that uses two components together to synergistically strengthen the base surface.

The defect of single-component products is: since the addition is completed at one time during use, the subsequent reaction direction cannot be further changed according to the material reaction process and microstructure changes, so it is impossible to further improve concrete hardness, wear resistance and other properties on the basis of conventional levels

In addition, there are also nominally two-component hardeners, but they need to be mixed before use. In fact, they are also single-component for concrete and other base surfaces, and cannot react according to the concrete base surface. Changes in the situation adjust the amount of the last component material to achieve the effect of synergistic reinforcement and hardening of the base surface
