The thermal conductivity of phenolic foam is about 0.023 (about 1 / 2 of that of polystyrene and about 0.042 of that of polystyrene board), the fire rating is incombustible grade A (150 ℃ high temperature resistance), and the price is similar to that of polyurethane. Polystyrene foam and polyurethane foam are flammable and not resistant to high temperature, which are being restricted by the fire department. Phenolic fire insulation board can effectively solve the problem of building fire protection and insulation. Phenolic insulation board does not melt, soften, emit smoke at high temperature, does not diffuse flame, resists flame penetration, has excellent fire protection performance, and has good heat preservation and energy conservation effect. It combines excellent fire protection performance with good energy conservation effect, and is suitable for external wall insulation. Application form of phenolic insulation board:
1) External thermal insulation of building exterior wall (thin plastering system, integration of thermal insulation and decoration, curtain wall system)
2) Central air conditioning composite air duct insulation (steel surface phenolic composite air duct, double-sided aluminum foil phenolic composite air duct)
3) Color steel sandwich panel field (movable plank house, purification engineering, clean workshop, cold storage, cabinet room, etc.)
4) Roof thermal insulation (residential roof, aquaculture ceiling, steel structure plant ceiling, roof thermal insulation)
5) Low temperature and cryogenic pipeline insulation (LNG pipeline, liquefied natural gas pipeline, cold and hot water pipeline)
6) Other fields requiring thermal insulation
Phenolic foam material has been greatly developed since the 1990s. It was first paid attention to by the British and American military and used in aerospace, national defense and military industries. Later, it was used in places with strict fire protection requirements such as civil aircraft, ships, stations, oil wells, and gradually pushed to high-rise buildings, hospitals, sports facilities and other fields.
