A pure inorganic coating

Abstract

The invention discloses a pure inorganic coating, which mainly comprises the following materials in parts by weight: 55 parts of calcium hydroxide, 8 parts of microsilica, 20 parts of silica solution, 2 parts of sodium chloride, 3 parts of aluminium hydroxide, 4 parts of attapulgite, 4 parts of , 4 parts of bentonite and 100 parts of water. The materials are mixed according to respective parts by weight, dispersed at high speed and filtered, and thereby the finished product is prepared. The calcium hydroxide, the microsilica and the silica solution are compounded to form a three-dimensional calcium-silicon structure of the pure inorganic coating, a great breakthrough is achieved in terms of strength, construction performance and the like, the fire-proof grade can reach grade A1, the pH value is about 13, and the pure inorganic coating is highly antibacterial. The invention provides the highly environment-friendly wall coating which is completely composed of inorganic mineral powders, the objective that the pure inorganic coating does not contain any organic chemical component is truly achieved, and the pure inorganic coating has a variety of advantages, such as environment protection, fireproofness, humidity resistance, mould-proofness and bacteria inhibition. The pure inorganic coating truly does not contain toxins, such as formaldehyde and VOC (volatile organic compounds).

Description

technical field [0001] The invention belongs to the technical field of inorganic coatings, and in particular relates to a pure inorganic coating. Background technique [0002] Most of the coatings in the prior art appear in the mixed mode of organic and inorganic, and organic substances are generally toxic, so the coatings in the prior art are usually not truly non-toxic. Coatings in the prior art are prone to mildew in humid environments, and mycoviruses are another important environmental hazard. In a high-temperature environment, especially during a fire, the gas volatilized by organic matter is flammable and highly toxic as the temperature rises. Coatings containing organic matter not only easily lead to the spread of fire, but also the main cause of fire death. To sum up, only pure inorganic coatings can achieve true environmental protection, fire prevention, mildew resistance and antibacterial effect. [0003] Although the inorganic coating patents in the prior art ...

AI Technical Summary

Problems solved by technology

Among them, the content of calcium hydroxide in the first two patents is too high, which leads to problems such as insufficient strength, difficult construction, easy precipitation, and poor color. The formulas of the latter three patents are basically not the actual ratio of calcium hydroxide as the main body. , so it is difficult to make the coatings to achieve the desired effect
