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

Abstract

The invention discloses a pure inorganic fire-retardant coating. The pure inorganic fire-retardant coating mainly comprises the following raw materials in parts by weight: 55 parts of calcium hydroxide, 20 parts of silica sol, 2 parts of sodium chloride, 15 parts of aluminum hydroxide, 4 parts of sepiolite, 4 parts of bentonite and 100 parts of water, and the raw materials are mixed, dispersed at high speed and filtered in parts by weight respectively to form a finished product. In order to achieve a better fireproof effect, mineral substances, namely hydroxyl-containing calcium hydroxide and aluminum hydroxide, are used, the total amounts of hydroxyl-containing calcium hydroxide and aluminum hydroxide account for 70% mass percent of dry matters of the coating, and the hydroxyl-containing calcium hydroxide and aluminum hydroxide release a large amount of water at high temperature to play the better fireproof effect. The pure inorganic fire-retardant coating disclosed by the invention completely comprises inorganic components, no organic component is added, the pure inorganic fire-retardant coating is free of toxins of formaldehyde, VOC and the like really, the fire rating of the pure inorganic fire-retardant coating reaches the level A1 and the pure inorganic fire-retardant coating is super-antibacterial. The pure inorganic fire-retardant coating with first-class fireproof performance is provided by the invention to create the highest standard of the inorganic coating in fire prevention.

Description

technical field [0001] The invention belongs to the technical field of inorganic coatings, and in particular relates to a pure inorganic fireproof coating. Background technique [0002] Most of the coatings in the prior art appear in a mixed mode of organic and inorganic, and organic matter is generally toxic, so it cannot be truly non-toxic, and the coatings in the prior art are prone to mold in humid environments, and mycoviruses are another type Important environmental toxicity. At high temperatures, especially during fires, as the temperature rises, the gases volatilized by organic matter are flammable and highly toxic. Organic coatings not only lead to the spread of fires, but are also the main cause of fire deaths. However, various extreme situations often appear in practical applications, and continuous improvement of technical indicators is the driving force behind the development of various technologies. [0003] In terms of fire protection, it is the most basic t...
