Introduction：From Tianjin Chemical Building Materials Co., Ltd. R & D production of foam insul
From Tianjin Chemical Building Materials Co., Ltd. R & D production of foam insulation material-specific fire protection foil, to laminating way fire insulation materials handling, not only has the high temperature, fire and other features, and operation simple, re-use, comprehensive cost is low, the market prospect is very broad. 
    As we all know, the current domestic exterior insulation commonly used in the construction of energy-saving materials, mainly EPS foam insulation board, aerated concrete and blocks and so on. Foam insulation materials which mainly include polystyrene foam plastic insulation membrane (eps board), insulation using extruded polystyrene foam (XPS extrusion board), building insulation rigid polyurethane foam (PU board ), etc.. Such insulation material has a thermal conductivity of small, low water absorption, sound insulation performance, high mechanical strength, merits, and therefore external wall insulation system is widely used. However, due to foam as the main component of organic matter, so there is flammable, especially at the construction site storage or adhesive on the wall after the cross in and welding engineering construction, can easily cause fires.
     Because EPS foam in the storage and security risks exist in the construction process, in April 2008, in order to implement the "prevention, fire with" fire-fighting approach to prevent foam insulation material due to the construction site caused by fire, Tianjin Construction Management Commission promulgated the "Tianjin building energy-saving foam insulation materials engineering at the construction site fire safety Interim technical requirements", requiring the foam insulation material factory before the completion of fire on the surface boundary layer treatment. Tianjin Chemical Building Materials Co., Ltd. for the foam insulation material at the construction site vulnerable to fire issues, to organize scientific and technological research, successful research and development to produce a foam insulation material-specific fire protection foil, laminating way to conduct fire insulation materials handling .
     It is understood that such fire protection film products fire-resistant coating is flame-retardant coating on the paper or any other tire made based on an organic - inorganic composite materials, when the temperature after the formation of a continuous dense glassy structure, with strong fire performance, can effectively prevent the flame to pass through and thus play a role in fire prevention. Fire interface layer of polymer cement mortar, specialty coatings, sheets or laminating handling, fire interfacial layer made of composite insulation board. EPS foam insulation board forming, it will fire foil insulation board affixed to the surface, just posted one-sided flame-retardant effect can be achieved. In the field of construction, the construction of the wiping surface exposed before the first fire tear up insulation foil core material, the foam insulation board without foil surface with exterior insulation bonding adhesive mortar on the wall, on the fire surface outwards, Plastering mortar can be directly carried out the construction, simple operation and maintenance of home without drying, the provincial workers save time, will not cause additional impact of thermal insulation system.
     Accordance with the "Tianjin building energy-saving foam insulation materials engineering at the construction site fire safety Interim technical requirements" set forth in the fire resistance testing methods, fire foil and special fire-resistant coating of fire-resistant properties of comparative experiment. The results showed that fire foil can be up to 1 minute over high-temperature environment, completely cut off the fire source, but also to maintain the integrity of the foil, with a more reliable fire-resistant properties. In practical applications, such products also have a more excellent fire retardant properties, which can effectively protect the EPS foam insulation layer to reduce the security risk.
