Steel structure fireproof coatings market prospects

Fireproof coatings are a class of coatings that are applied to the surface of an object to prevent fire from occurring, prevent the spread of fire or isolate the source of the fire, prolong the fire time of the substrate or increase the insothermal properties to delay the time of structural damage. Building fire prevention is an important field of fire science and technology, and fire protection coating is an important part of fire prevention building materials.Steel structure, as a form of high-rise building structure, has been widely used in the construction industry because of its high strength, light quality, good extension, earthquake resistance and short construction cycle, especially in super-high-rise and large-span buildings and other aspects show strong vitality
1990, steel structures accounted for 79% of the world's 100 super-high-rise buildings with a height of more than 200m. Since the reform and opening up, with the strengthening of international technology exchanges and cooperation, steel structure application technology has been booming in China, high-rise and super-high-rise buildings are growing rapidly.
1995 statistics, China's 100 super-high-rise buildings accounted for 37% of the steel structure, most of which have been built in recent years. With the development of China's urban scale, the application of steel structure in China's construction industry has a very broad prospect.
because the steel structure itself is not burning, the protection of the steel structure's fire insulation was once neglected. According to relevant information reports at home and abroad and the tests and statistics of relevant institutions, the fire resistance of steel structures is worse than that of masonry structures and reinforced concrete structures.The mechanical strength of
steel decreases with the increase of temperature, at about 5000 degrees C, its strength drops to 40% to 50%, and the mechanical properties of steel, such as yield point, pressure resistance, elastic modus and load capacity, are rapidly decreased, and soon lose support capacity, resulting in the collapse of the building.
, it is imperative to protect the steel structure. Steel structure fire protection coating brush or spray on the surface of the steel structure, fire insulation, to prevent steel in the fire heating up quickly and reduce the strength, to avoid the steel structure lost support capacity leading to the collapse of buildings.
as early as the 1970s, foreign research and application of steel structure fire-resistant coatings have carried out positive work and achieved better results, which is still on the rise. In the early 80's, foreign steel structure fire protection coating entered the Chinese market and was applied in engineering. Since the early 80's, China has also begun to develop steel structure fire protection coatings, so far there are many excellent varieties widely used in all walks of life.
with the further intensity of urban construction and development in China, steel structures, because of their steel and plasticity are relatively good, will be widely used in large-scale exhibitions, sports centers and high-rise buildings. Therefore, it is necessary to further study the fire-resistant coating properties of steel structures, improve the fire resistance limit of steel structures according to different needs and functions, enhance the fire resistance of buildings, and ensure the safety of life and property of the state and the people.of fire protection coatings in China started late, but the development rate is very fast. In the late 1970s, the expansion type of perchloroethylene fireproof coating was first studied, and later the expansion type of acrylic latex fire protection coating was studied. Since the mid-1980s, the Institute of Science has pioneered the development of LG steel structure fire protection coatings. At present, the country has more than 220 fire-resistant paint production enterprises, and Nanxuan No. 1 9 Ministry of Public Security 3c certification enterprises to hire only 6.
at the same time in recent decades, the development of fire-resistant coatings is on the rise, its water resistance, fire resistance has been greatly improved and improved, varieties and applications continue to expand. Some countries have also designated laws that require paint used in public buildings such as schools, hospitals and cinemas to be flame retardant or not allowed to be built. It can be seen that fire-resistant coatings have attracted great attention.
