Summary of the invention
The technical problem that the present invention solved provides a kind of Rigid foam polyurethane and production method thereof of grinding; The composite plate that adopts this method to make not only has excellent fire prevention, waterproof, heat-insulating property; Also strengthened caking property with body of wall; More outstanding is that plate surface can be modified polishing, greatly reduces the requirement to the construction wall planeness, has improved efficiency of construction simultaneously significantly.
In order to achieve the above object, the technical scheme of the present invention's employing is:
A kind of Rigid foam polyurethane that grinds comprises hard-foam polyurethane insulation layer that is positioned at the intermediate layer and the polymer cement boundary layer that is positioned at hard-foam polyurethane insulation layer upper and lower surface; Said polymer cement boundary layer is in the foaming process of hard-foam polyurethane insulation layer, directly to be compounded in said hard-foam polyurethane insulation layer upper and lower surface; Said polymer cement boundary layer employing can directly be polished and the material of waterproof fireproofing is processed.
The present invention is through the direct composition polymer cement interface layer on the foamed polyurethane layer two sides; Said polymer cement boundary layer employing can directly be polished and the material of waterproof fireproofing is processed; Make the surface of the Rigid foam polyurethane after processing directly to modify polishing, greatly reduce requirement, and composite plate is easy to body of wall bonding the construction wall planeness; Adhesion is high, is difficult for dropping; Also contain the waterproof fireproofing material simultaneously, have the excellent waterproof fireproof performance.Said can directly polish and the material of waterproof fireproofing is preferably processed by polymer gel material, inorganic powder and fire retardant; Said polymer gel material is one or more in polyacrylic resin, waterborne polyurethane resin, the EVA resin; Said inorganic powder is one or more in cement, river sand, quartz powder, dicalcium powder, the natural sand; Said fire retardant is one or more in TCEP, TCPP, TDCPP, DMMP, APP, triphenyl phosphate, antimony oxide, magnesium hydroxide, aluminium hydroxide, the silicon-series five-retardant.The consumption of wherein said polymer gel material can be adjusted between mass concentration 0.5-90%, to obtain the product of different stability, weatherability.The principle of allotment is as the criterion with the film or the layer structure that can form stable in properties.
There are not net material or facestock material in the Rigid foam polyurethane that grinds of the present invention, wherein said polymer cement boundary layer as skeleton.
Production method of grinding Rigid foam polyurethane of the present invention: can directly polish and the material of waterproof fireproofing can grind polymer cement interface coiled material being coated on the production line to produce on the carrier film of compatibility difference with it, the said polymer cement interface coiled material that grinds is said polymer cement boundary layer; Can grinding polymer cement interface coiled material then, to divide upper and lower faces to pass through tensile stress docile on the upper and lower carrier bar of the continuous foamed line of polyurethane; Again polyisocyanates and combination material mixture are cast in and grind between the coiled material above and below, polymer cement interface uncoiling and carry out continuous foamed; After the moulding outlet carrier film is taken off, processed and to grind Rigid foam polyurethane; Middle foaming layer is said hard-foam polyurethane insulation layer.
Aforementioned production method, wherein said can directly polish and the material of waterproof fireproofing is processed by polymer gel material, inorganic powder and fire retardant; Said polymer gel material is one or more in polyacrylic resin, waterborne polyurethane resin, the EVA resin; Said inorganic powder is one or more in cement, river sand, quartz powder, dicalcium powder, the natural sand; Said fire retardant is one or more in TCEP, TCPP, TDCPP, DMMP, APP, triphenyl phosphate, antimony oxide, magnesium hydroxide, aluminium hydroxide, the silicon-series five-retardant.
Aforementioned production method, wherein said carrier film are a kind of in polyolefin plastics film, release liners, the pad pasting kraft.
Aforementioned production method, wherein said combination material are one or both of combined polyether glycol, combination PEPA.
The Rigid foam polyurethane that grinds of the present invention can be modified polishing when last wall is constructed, and not only has excellent waterproof thermal-insulated performance; And the system fire prevention is outstanding; And reduced requirement to the foundation construction degree of plainness for wall surface, easy construction, efficient is 1.5 times of conventional polyurethanes composite plate construction.
Production method of grinding Rigid foam polyurethane of the present invention can adopt factory's serialization to produce; Production efficiency is high; A large amount of cost of production and construction cost have been saved; And sheet material in light weight, planeness is high, fireproof performance good, also can cut arbitrarily, can improve the efficiency of construction of thin plastoring system greatly.
