Fire prevention to strengthen and classification of external wall insulation technology phenolic insulation board
new buildings in our country and existing buildings energy saving reconstruction of building energy efficiency market is huge, both at home and abroad practical experience proved that exterior insulation technology system in building energy saving and comfortable indoor environment of obvious advantages, is a suitable way, is also a key development project by the ministry of construction, has a good application prospect; But the technical level of the good and bad are intermingled, which leads to the fake and inferior products flooding the market; Also because of this, our exterior insulation production enterprise backbone enterprises, leading companies, in particular, should actively strengthen technology research and development and r&d, from raw material performance, technology, system principle, the mechanical properties of mechanism, the respect such as large weathering experiment study and work, perfect technology system, provide good performance and stable thermal insulation technology and products.
fire A variety of exterior wall thermal insulation material points, according to the date file fire rating is divided into:
grade A for non-combustible material for inorganic heat preservation material, cement foam insulation board, vitrified beads insulation mortar, rock wool board, glass wool board, etc.
B hard material, most of the organic material, add a lot of flame retardants, such as polystyrene, extruded board, phenolic board, polyurethane board, etc.
B as fire retardant material, also known as the flame retardant materials, more for organic heat preservation material, adding the right amount of flame retardants.
if the heat preservation effect is good, extruded board, polyurethane, phenolic plate heat preservation effect best, polystyrene board, vitrified beads insulation mortar, rock wool board is a regular.
phenolic plate made of phenolic foam, phenolic foam is a macromolecule organic rigid aluminum foil foam products, is composed of thermosetting phenolic resin foam. Phenolic insulation board has been widely used in developed countries.
