Zhang Lixin, a researcher at the Institute of Building Fire Protection at the Chinese Academy of Building Research, said that the coating is based on neoprene latex as a binder, expanded graphite as an intumescent material and aluminum hydroxide flame retardant, reinforcing agent, and other additives. Composition of elastic expansion coating. The coating's elasticity, flexibility and other properties all reached the highest level in the country. This coating overcomes the problem of “blown fly†after the general “expanded graphite coating†is exposed to fire. At the same time, the “carbonized intumescent layer†of the coating has high strength, and it can be widely applied to the surface of various building components and building materials. Fire protection layer. When this kind of coating is used for fire shutter doors, their heat radiation can be greatly reduced. When the coating is applied to a glass fiber cloth, the tear strength can be increased by 53.4%, and the elongation at break can be increased to 362%.
“Elastically Expandable Insulation Coating†Appraisal by National Expert Group
Recently, the “Flexible Expansive Thermal Insulation Coatings†independently developed by three researchers of the Institute of Building Fire Prevention, Chinese Academy of Building Research, have been successfully developed. The expert group organized by the China Academy of Building Research has identified that the overall technical level of this achievement has entered the international advanced ranks.
