Description
Technical field
The invention discloses a kind of water-proof heat-insulating slabs, belong to building material technical field.
Background technology
When carrying out construction, not only the stability to roof board material structure and durability degree have certain requirement, to room
The waterproof thermal-insulated processing of face plate construction is also a wherein important ring.Waterproof layer and insulating layer are point in traditional roofworks
It opens up and sets, the consumption of manpower and material can be increased in the construction process, and the two junction is not by any reinforcing
Reason causes water to be easy to flow into from the gap that the two connects so that the water absorption rate of insulating layer is high, causes hidden leakage defect, serious shadow
Ring the quality of construction.
Thermal insulation board is to add other supplementary materials and poly- inclusion by raw material of polystyrene resin, by heating mixing simultaneously
Injecting catalyst, then extrusion molding extrusion molding and the rigid foam plate that manufactures, have moisture-proof, water resistance, can make reduction
Building envelope thickness, to increase indoor usable floor area.
Thermal insulation board is common to be divided into XPS thermal insulation boards and polyurethane thermal insulation board.XPS thermal insulation boards, it is with polystyrene resin
Be that raw material adds other supplementary materials and poly- inclusion, by heating mixing injecting catalyst simultaneously, then extrusion molding extrusion molding and
The rigid foam plate of manufacture.Its scientific name is extrusion molding polystyrene polyfoam for heat insulation（Abbreviation XPS), XPS has had
Beautiful closed honeycomb structure, this structure allow XPS plate to have extremely low water imbibition（Hardly absorb water）, low thermal conductivity coefficient, high resistance to compression
Property, ageing resistance.Hard polyurethane board thermal coefficient is low, and thermal property is good.Hard polyurethane board has moisture-proof, water resistance.
The rate of closed hole of hard polyaminoester belongs to hydrophobic material 90% or more, will not increase thermal coefficient because of the moisture absorption, metope will not
Infiltration.Hard polyaminoester is prevented fires, fire-retardant, high temperature resistant.Polyurethane is a kind of fire retardant self-extinguishing after adding fire retardant,
Its softening point can reach 250 degrees Celsius or more, and decomposition is only just will appear in higher temperature, in addition, polyurethane meeting in burning
Ash is formed in its foam surface, this layer of ash, which helps, is isolated following foam, can be effectively prevented fire spread.Moreover, polyurethane
Pernicious gas is not also generated at high temperature.Since polyurethane plate has excellent heat-proof quality, reaching same thermal requirements
Under, reduction building envelope thickness can be made, to increase indoor usable floor area.There is also guarantors for thermal insulation board traditional at present
Warm nature energy and the bad problem of water resistance, therefore also need to study it.
