Abstract
The invention relates to a steel structure fireproof paint. The paint comprises the following components by mass fraction: 20-40 parts of aqueous resin, 50-60 parts of silicon dioxide-alumina mixture, 5-10 parts of titanium dioxide, 0.5-1 part of melamine and 5-10 parts of tricresyl phosphate. The steel structure fire-resistant paint can tolerate long-term high-temperature roasting, has fire prevention and heat insulation effects, can prevent steel from rapidly warming in fire so as to reduce strength, and avoids the steel structure from losing support capacity to result in collapse of a building.
Description
Technical field
The invention belongs to frie retardant coating technical field, particularly relate to a kind of frie retardant coating for steel construction.
Background technology
Steel construction is as a kind of form of high building structure, high with its intensity, quality is light, and have the features such as good extensibility, shock resistance and short construction period, be used widely in construction industry, especially in Super High and long span building etc., demonstrate powerful vitality.At the bottom of cut-off nineteen ninety, in 100 high-rise buildings of high more than 200m in the world, steel construction account for 79%.Since reform and opening-up, along with the reinforcement of international exchange of technology and cooperation, steel construction utilisation technology obtains flourish in China, and high-rise and high-rise building increases rapidly.According to the statistical information of nineteen ninety-five, in the 100 building high-rise buildings that China builds up, steel construction accounts for 37%, and majority was built in recent years.Along with the development of China's city size, steel construction has boundless prospect in the application of Building Trade in China.But because steel construction self does not fire, the fire-proof and thermal-insulation protection problem of steel construction was once once ignored by people.Show according to the test of domestic and international pertinent data report and appropriate authority and statistical figure, the fire performance of steel building comparatively masonry structure and skeleton construction poor.The physical strength of steel reduces with the rising of temperature, and at about 5000 DEG C, its strength degradation is to 40% ~ 50%, the mechanical property of steel, such as yield-point, ultimate compression strength, Young's modulus and weight bearing power etc. decline all rapidly, lose supporting capacity very soon, cause buildings to collapse.Therefore, protection is carried out to steel construction imperative.Steel structure fire-proof paint is brushed or is sprayed on steel structure surface, plays fire-proof and thermal-insulation effect, prevents steel rapid temperature increases and reduce intensity in a fire, avoids steel construction lose supporting capacity and cause buildings to collapse.As far back as 20 century 70s, positive work just expanded to the investigation and application of steel structure fire-proof paint abroad and achieve good achievement, being still in the ascendant so far.The beginning of the eighties, external steel structure fire-proof paint just entered Chinese market, and engineering is applied.From the beginning of the eighties, China also starts to develop steel structure fire-proof paint, and existing many improved seeds are widely used in all trades and professions so far.
Summary of the invention
The technical problem solved: the present invention aims to provide a kind of steel structure fire-proof paint, can be used for the fire prevention of the civilian steel construction that buildings and accessory, movable furniture, carpet, clothing, household electrical appliance etc. cause.
Technical scheme: steel structure fire-proof paint, consists of the following composition by massfraction: water-base resin 20 ~ 40 parts, 50 ~ 60 parts, silica-alumina mixture, titanium dioxide 5 ~ 10 parts, trichlorine hydrogen ammonium 0.5 ~ 1 part, tritolyl phosphate 5 ~ 10 parts.
Described water-base resin 30 parts.
60 parts, described silica-alumina mixture.
Described tritolyl phosphate 8 parts.
Beneficial effect: steel structure fire-proof paint of the present invention, can tolerate long high bake, plays fire-proof and thermal-insulation effect, prevents steel rapid temperature increases and reduce intensity in a fire, avoids steel construction lose supporting capacity and cause buildings to collapse.
