Abstract

The invention discloses an inorganic fireproof material and a preparation method thereof, and belongs to the field of fireproof materials. A coating of the fireproof material mainly comprises alumina sol as a film forming matter, diatomite as filler and some trace auxiliaries, wherein the alumina sol is a water-based inorganic binder and has the characteristics of no toxity, high temperature resistance, high binding force, environmental protection and the like; the diatomite has porous heat insulation and can obviously prolong duration of fire resistance; the performances of the coating such as adhesive force and duration of fire resistance can be obviously enhanced by adjusting the percentage composition and the thickness of the coating. The raw materials used are all low in cost, and are non-toxic and harmless inorganic materials; the coating is expanded and foamed during the heated process to form a loosened porous expansion layer with an extremely good heat insulation effect, and meanwhile hazardous gas is not generated; the duration of fire resistance is over 60 minutes; the coating can be coated on various modern buildings with wood structures and steel structures, and can be applied to the field of fireproof coatings well.

Description

technical field [0001] The invention relates to an inorganic fireproof coating and a preparation method thereof, belonging to the technical field of special materials. Background technique [0002] The fire is mainly due to the lack of protection of low-flammability substances. If a high-temperature-resistant coating can be applied to the surface of furniture to reduce the flammability of the surface of the coated material and retard the rapid spread of the fire, it can be used to increase the fire-resistant limit of the coated material. It will be able to effectively protect low flash point substances to delay or prevent the occurrence of fire. This project uses aluminum sol and diatomite as the main raw materials to invent a new type of coating with low cost, environmental protection, air purification and effective improvement of the fire resistance of the substrate. [0003] At present, the most indoor wall paint is latex paint. Latex paint is an organic paint that will ...
