Abstract
An inorganic nano stock solution relates to the technical field of additives. The inorganic nano stock solution comprises the following raw materials in percentage by mass: 50-80% of silicon nitrogen nano polymer, 10-20% of high-efficiency water reducing agent, 0.01-2% of inorganic active agent, 0.01-1% of water-based defoaming agent, 0.01-5% of nano silicon compound and 0.01-2% of inorganic polymer.

Background
In the prior art, most of products such as cement products, artificial stones, inorganic stones, GRC members, RPC members, fabricated members, high-strength self-leveling and high-performance concrete mainly use resin and emulsion organic composite materials, and the additives have the defects of environmental pollution, pungent taste, heat resistance, fire resistance, alkali resistance, acid resistance, corrosion resistance, poor water resistance, poor cracking resistance, poor sunlight irradiation resistance, poor self-compaction, poor surface light, high cost and the like. Therefore, how to solve the serious problem of the interweaving of various interactions at one time has become the focus of attention of many researchers of inorganic nanomaterials.
Disclosure of Invention
In order to solve the above disadvantages of the existing inorganic additives, the present invention aims to provide an inorganic nano stock solution used in products such as cement products, artificial stones, inorganic stones, GRC members, RPC members, fabricated members, high-strength self-leveling, high-performance concrete, etc., so as to improve the performance of the products.
The technical scheme adopted by the invention is as follows:
an inorganic nano stock solution is prepared by mixing the following raw materials in percentage by mass: 50-80% of silicon nitrogen nano polymer, 10-20% of high-efficiency water reducing agent, 0.01-2% of inorganic active agent, 0.01-1% of water-based defoaming agent, 0.01-5% of nano silicon compound and 0.01-2% of inorganic polymer.
The silicon nitrogen nano polymer is a high-temperature resistant inorganic polymer, can be used under the severe conditions superior to those of metal or ceramic, can still keep the unique toughness and hardness under the corrosion and high-temperature conditions, and has good heat insulation, corrosion resistance and heat resistance superior to those of ceramic.
The high-efficiency water reducing agent is a cement admixture capable of reducing the mixing water consumption, most of which belongs to anionic surfactants, and comprises lignosulfonate, naphthalene sulfonate formaldehyde polymer and the like.
The inorganic active agent is mainly compounded by metal oxide, hydroxide and basic carbonate.
The water-based defoaming agent is prepared from dimethyl silicone oil, white carbon black, an emulsifying agent and the like, all raw materials and links are nontoxic, and the water-based defoaming agent has the characteristics of high dispersing speed, high defoaming speed, long foam inhibition time, stability and no layering.
The nano silicon compound refers to crystalline silicon particles with the diameter less than 5 nanometers, has the characteristics of large surface area, high surface activity and low apparent density, and is non-toxic, tasteless and good in activity.
The inorganic polymer is an inorganic macromolecular substance, and the main chain can be formed by atoms of other various elements. The main chain composed entirely of the same kind of element is called "homochain", and the main chain composed of atoms of different kinds of elements is called "heterochain".
The invention has the beneficial effects that: the practical application proves that in the manufacturing production of cement products, artificial stones, inorganic stones, GRC members, RPC members, assembled members, high-strength self-leveling concrete and other products, the performance of the products can be greatly improved only by adding a small amount of inorganic nano stock solution, the serious problems of mutual interweaving of various functions such as thermolabile property, refractoriness, alkali resistance, acid resistance, corrosion resistance, poor water resistance, poor cracking resistance, poor sunlight irradiation resistance, poor self-compactness, poor surface light, high cost and the like of the products such as the cement products and the like can be solved at one time, and the inorganic nano stock solution can not generate pungent smell, is a new generation of environment-friendly inorganic additive, and fills the blank that no inorganic nano stock solution exists in the prior art.
