Description

General inorganic coating with non-combustible function for interior and exterior walls
Technical Field
The invention relates to the field of coatings, in particular to a non-combustible inorganic coating for interior and exterior walls.
Background
The inorganic building coating is prepared by taking alkali metal silicate, silica sol and the like as main adhesives and adding pigments, fillers, auxiliaries and the like, and a thin decorative and protective coating is formed on the surface of the outer wall of a building by adopting a brushing, spraying or rolling coating construction method; it has the advantages of weather resistance, air permeability, environmental protection, non-inflammability and the like, and can be widely applied to architectural engineering coating instead of synthetic resin emulsion coating. As the raw materials of the organic building coating are mainly petrochemical products or derivatives, the problem of environmental pollution caused by the exterior wall building coating cannot be fundamentally solved, and a large amount of byproducts, volatile solvents and residual monomers are generated during processing, thereby not only causing environmental pollution, but also wasting a large amount of resources and energy. Meanwhile, the latex paint has the problems of poor weather resistance and stain resistance, easy dusting and shedding of a coating and the like. After two or three years of construction, the phenomena of coating pulverization, fading and shedding can occur.
Inorganic silicate coatings have a long history and have been widely used in europe for nearly one hundred and forty years, and according to statistics, the inorganic silicate coatings account for about 15-20% of the architectural coating market in europe today. Although the inorganic coating in China is applied in the eighties of the last century, the inorganic coating is really valued by people and is still a matter in recent years. The first generation of inorganic paint is based on silicate (commonly called water glass) produced by melting quartz sand and alkali carbonate or dissolving active silicon source (main quartz sand) with alkali, and is prepared with high weather resistance inorganic pigment; the inorganic coating has the advantages of ultraviolet resistance, no VOC, bactericide, emulsifier and the like, the service life can reach dozens of years or even hundreds of years, but the decoration effect, the stability and the simplicity degree of the construction performance are difficult to meet the requirements. The second generation inorganic silicate latex paint appeared in the fifth and sixties of the last century combines a silicate inorganic binder and an organic synthetic emulsion binder together, so that the stability is improved, and the experiment single-component package is more convenient to use. The third generation inorganic silica sol-silicate coating appearing at the beginning of the century is added with silica sol on the basis of the second generation, so that the curing shrinkage stress of the inorganic silicate coating is reduced, the crack resistance is improved, and the application range is further expanded to the surface of a non-mineral substrate.
The current technology mostly stays on the basis of the second generation and the third generation, but companies also put forward products of the fourth generation and the fifth generation, and the new-generation products are not completely and clearly defined. The fourth generation inorganic coating technology proposed by a certain company improves the curing speed and the paint film performance of the inorganic coating by the controllable active filler participating in the crosslinking reaction, so that the inorganic coating can be used for the outer wall protection in tropical rainy areas, and the performance of the single-component pure inorganic coating is greatly improved. German paint company has hundreds of years of history in the research and production of inorganic paint, is the company with the earliest research in the industry and the most mature product system, and produces an inorganic paint which takes alkali metal silicate as a film-forming substance and has the service life of more than 20 years. It is understood that there are no more few companies that research inorganic coatings domestically, and there are many types of products on the market, but the specific application examples are not extensive.
Disclosure of Invention
Technical problem to be solved
In order to solve the problems in the prior art, the invention provides the inorganic coating with the non-combustible function for the inner wall and the outer wall, wherein the inorganic coating is used for the inner wall and the outer wall and has the non-combustible function.
(II) technical scheme
In order to achieve the purpose, the invention adopts the main technical scheme that:
a general inorganic coating with a non-combustible function for internal and external walls is composed of the following raw materials in percentage by weight:
Figure BDA0002831311030000021
Figure BDA0002831311030000031
furthermore, the purity of the talcum powder and the calcined kaolin is required to be more than 99%, and the talcum powder and the calcined kaolin belong to inert fillers, and the fineness of the talcum powder and the calcined kaolin is between 700 and 2000 meshes.
Further, the inorganic silicone resin is an organically modified silica sol.
(III) advantageous effects
The invention has the beneficial effects that: 1. selecting stabilized inorganic silicate resin, coating silicon hydroxyl on the surface of silicate with aluminum dioxide, when water molecules are lost, breaking the aluminum dioxide coating film to release silicon hydroxyl, and then reacting the silicon hydroxyl to form a paint film with higher strength. If the silica sol is not subjected to stabilization treatment, the surface activity is too large, the coating is easy to coke when being prepared, and the product stability is not enough; if stabilization treatment with a silane coupling agent or the like is performed, silicon hydroxyl groups are consumed, and the performance during film formation does not meet the requirement; the particle size of the silica sol is strictly controlled, and the large particle size can cause risks such as cracking and the like.
2. Inert powder materials such as chemically inert nano titanium dioxide (rutile titanium dioxide) and chemically inert wollastonite are added, the stability of the product is greatly improved, the scrubbing resistance of the product can be effectively improved by the type matching and the particle size matching of the powder materials, and the physical strength of the system is improved by adding sand into a model similar to concrete; the acrylic emulsion is styrene-acrylic emulsion, and the wet wiping-off performance of the coating and the salting-out performance of the outer wall can be improved by adding the emulsion.
