Nano inorganic gel modifier and preparation method thereof

Abstract

The invention provides a nano inorganic gel modifier and a preparation method thereof, and relates to the field of engineering materials, the nano inorganic gel modifier comprises the following components in percentage by weight: 20-30 parts of nano inorganic resin, 10-20 parts of a nano modifier, 4-12 parts of a water-retaining agent water-soluble rare earth prepared from lanthanide series soluble rare earth salt, 0-0.6 part of a dispersing agent prepared from inorganic aerogel, 0-0.4 part of a defoaming agent prepared from a water-soluble silane defoaming agent, 0-3 parts of a thickening agent formed by mixing various hydroxypropyl methyl cellulose with different viscosities, and 40-60 parts of deionized water. In the invention, the nano inorganic gel modifier is used as a core material, is added into highly mechanically activated inorganic materials such as fly ash, saw mud, brick ash, steel slag, petuntse, red mud and the like, and is stirred at a high speed, so that a resin-like viscous inorganic new material can be synthesized, and the nano inorganic gel modifier is a novel material which has an application prospect and excellent environment-friendly performance.

Description

technical field [0001] The invention relates to the field of engineering materials, and in particular to an inorganic gel modifier and a preparation method thereof. Background technique [0002] Existing science and technology generally believe that only the polymer structure formed by organic matter has the characteristics of resin, which manifests film-forming compactness, high cohesiveness, flexibility, etc. This characteristic is formed by crystallization and bonding of coarse and fine aggregates to form concrete What cement does not have, and therefore, for ultrafine aggregates such as tailings and aeolian sand, ordinary cement concrete can be added in a very limited amount and cannot be used on a large scale. However, organic polymer resins belong to the chemical industry and cause environmental pollution. Huge impact, at the same time the cost is extremely expensive, and at the same time, it is difficult for organic materials to achieve fire resistance and high temper...

[0002] Existing science and technology generally believe that only the polymer structure formed by organic matter has the characteristics of resin, which manifests film-forming compactness, high cohesiveness, flexibility, etc. This characteristic is formed by crystallization and bonding of coarse and fine aggregates to form concrete What cement does not have, and therefore, for ultrafine aggregates such as tailings and aeolian sand, ordinary cement concrete can be added in a very limited amount and cannot be used on a large scale. However, organic polymer resins belong to the chemical industry and cause environmental pollution. Huge impact, at the same time the cost is extremely expensive, and at the same time, it is difficult for organic materials to achieve fire resistance and high temperature resistance, and at the same time, it is easy to age, and the performance of resistance to salt spray and acid-base salt solution is relatively insufficient, so it is possible to modify inorganic substances into organic polymer resins. It has become a new prospect in the field of new materials

[0003] The inventors have found that the surface activation energy can be stimulated by grinding the industrial and mining solid waste to the quasi-nano level through modern grinding equipment, but at this time the activation energy still cannot generate a strong adhesive force similar to that of polymer resin.
