Phenolic insulation board in the application of the developed countries and to promote the development of thermal insulation market
phenolic board has good insulating light, stays, big stiffness, good dimensional stability, expansion coefficient similar to aluminum, is a kind of refractory material. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS exterior wall thermal insulation system fire belt/PU, will be used for fire prevention in the curtain wall thermal insulation materials, fire door insulation materials, as well as low or high temperature of fire insulation material. Burns, produce only a small amount of carbon monoxide poisonous gas, low smoke, won't melt, no drop of material, lower production cost. The main structure of the product based on phenolic foam core material, the surface is composed of polymer mortar and glass mat reinforced composite layer. As the research object, to a factory of phenolic foam on the surface of the polymer mortar with mesh cloth composite process is studied. The influence of temperature on the strength of phenolic foam is not obvious. At low temperature ( Uniform - 196℃) , phenolic foam plastic mechanical strength contractive, not brittle, phenolic foam mechanical strength basically remain unchanged, in under the condition of 150 ℃ continuous force, can keep the original strength of 90%.
can be phenolic board and surface decoration materials combine to form a cavity structure, it will be a good choice, so we just consider the bonding between the phenolic foam and surface decoration materials. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam thermal insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam thermal insulation material is qualitative light, construction is convenient wait for a characteristic. Production is not very complicated, there are a large number of polyurethane insulation cavity type insulation decorative sheet, if the phenolic resin instead of pu will be a very good choice.
