Abstract

The invention discloses a fire retardant coating of a super thin steel structure and a preparation method thereof. The fire retardant coating is prepared from the following raw materials in parts by weight: 30 to 40 parts of amino resin, 10 to 20 parts of megilp, 20 to 30 parts of APP (ammonium polyphosphate), 2 to 10 parts of titanium dioxide, 5 to 12 parts of melamine, 5 to 12 parts of pentaerythritol, 0.5 to 1.5 parts of bentonite, and 2 to 4 parts of chlorcosane. The related indexes of the fire retardant coating of a super thin steel structure meet the national standard, the toxic gas release does not exist in a work process, safety and environmental protection are realized, and the fire retardant coating can be widely used in various steel construction, two data of the surface dry time and the fire endurance thereof are superior to the national standard, the effect is obvious, and the great market value is achieved.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, and in particular relates to an ultra-thin steel structure fireproof coating and a preparation method thereof. Background technique [0002] Steel structure is a common structural form of modern buildings. It has many advantages such as high strength, strong load, light weight, and small size. With the rapid development of my country's economic construction, steel structure buildings appear in large numbers in public buildings, commercial buildings and other high-rise buildings. And in industrial plants, although the steel structure has many advantages, it also has the problem of poor fire resistance, especially when the temperature reaches 400-600°C, the strength of the steel structure decreases linearly, and when the temperature reaches above 600°C, the steel structure The structure has almost lost its load-bearing capacity. Therefore, it is very important to take effective protection...
