The coating can be applied to the fire protection of steel structure and concrete at the same time. A new type of physical expansion flame retardant is developed, which is mainly made of expandable graphite. It is halogen-free, environmental friendly and has excellent fire performance. However, foreign scholars have developed the inorganic fire-retardant coating for building surface, which is composed of hydraulic white cement, water glass, vermiculite, expanded perlite, inorganic glass fiber, etc. the fire-retardant coating mainly composed of sepiolite, calcium silica, reinforced fiber, high aluminum cement and amorphous silica is introduced. The coating has good thermal insulation and explosion-proof crack resistance, and can be applied to the exterior wall of buildings , tunnel, etc.; fire retardant coating for metal and concrete surface, filled with bentonite, aluminum silicate, wollastonite, magnesium silicate, glass beads and some porous materialsThe binder is one or more of water glass, Portland cement, gypsum and phosphate. The above-mentioned tunnel fire retardant coatings are made of water glass, cement, white cement, high aluminum cement, phosphate and other inorganic materials as binders. Due to the large amount of binder, it is necessary to consider the price of the material, combustion performance and smoke in case of fire when choosing binder. Fire resistant filler: it is one of the framework components of the tunnel fire retardant coating, accounting for about 35% - 38% of the total volume of the coating, and its main role is to heat insulation at high temperature and reduce thermal conductivity. Sepiolite, expanded perlite, light calcium carbonate, hollow glass beads, kaolin, slag cotton, superfine aluminum silicate are all good inorganic light heat insulation fillers. Intumescent agent: it is another main component of tunnel fire retardant coating, accounting for about 8% - 10% of the total volume of the coating. When the temperature is high, the composition of the coating changes and the expansion agent expands rapidly, thus forming a porous insulation layer to prevent the heat transfer to the tunnel masonry. Expanded vermiculite and ammonium dichromate are inorganic foaming materials; melamine, ammonium polyphosphate are mature organic foaming systems, which are mostly visit here used in thin or ultra-thin fire retardant coatings. Flame retardant: it is used for flame retardant of coatings, accounting for about 12% - 15% of the total volume of coatings. It absorbs heat and water loss when heated, and assists in expansion and heat insulation. Borides, zincifiers, aluminum hydroxide and magnesium hydroxide with more crystal water are generally selected. Other additives: mainly improve the workability and physical and chemical properties of the coating, accounting for about 3% - 5% of the total volume of the coating. Common additives are redispersible latex and high efficiencyWater reducing agent, etc. What should be paid attention to during the construction of tunnel fire retardant coating? If the slurry is too dry during mixing, the water cement ratio can be increased appropriately, whichever is sbs steel buildings suitable for construction; in the process of mixing, spraying and coating, the scattered and rebounded slurry can be recovered and used in time; the polluted and over 2H can't be reused; once the coating packaging bag is opened, it shall be used immediately, and the coating with damp and caking shall not be used; construction process It can be adjusted according to the design thickness and construction conditions of the coating. As for the outdoor ultra-thin fire retardant coating for steel structure, the non expansive and pollution-free water-borne organic-inorganic composite coating should be generally used in the research of tunnel fire retardant coating. The fire protection of tunnel structure in China began in the mid-1980s, but limited to the technical and economic conditions at that time, except for the limited number of tunnels such as the river crossing tunnel sprayed with fire retardant coating, no fire protection measures were taken for other tunnel structures. It is a matter of recent years to design and build tunnels in accordance with relevant tunnel design specifications. The application of tunnel fire retardant coating began around 2001. At that time, some enterprises used thick steel structure fire retardant coating or concrete floor fire retardant coating or cable fire retardant coating as tunnel fire retardant coating. Therefore, the foundation of research on tunnel fire retardant coating is relatively weak, and the products are uneven, which brings great difficulties to the construction and performance test of tunnel fire retardant coating. At present, the main defects of tunnel fire protection in China are as follows: the coating is too thick as per ISO834 curve. Outdoor ultra thin fire retardant coating for steel structure 25KG / bag. Therefore, the thick fire retardant coating cannot be exposed to sunlight or damp, and should be stored in a cool and dry warehouse. The effective storage period of the thick steel structure fire retardant coating is half a year. It shall be stored in a cool and dry warehouse with a storage temperature of 3 ℃ ~ 40 ℃. It is necessary to prevent exposure to the sun and rain, and the material will fail if it is damp. The thick steel structure fire retardant coating is a powder product that is non combustible, non explosive, non-toxic and non corrosive, which can be used for railway, highway, waterway and air transportation. During transportation, it is necessary to prevent rain, collision and binding. Ultra thin steel structure fire retardant coating is a non combustible, non explosive, non-toxic and non corrosive safety product. It is strictly prohibited to transport it according to general goods, rain, sunlight exposure, storage temperature - 10 ℃ - 40 ℃, and transportation is the same as ordinary paint. Generally, the ultra-thin steel structure fire retardant coating is packed in iron barrel, 20kg per barrel, with a limited period of one year. It is stored and transported to prevent exposure, rain, heavy pressure and inversion. The thin steel structure fireproof coating is packaged in plastic barrel.
