Background technology
At present, China is in the roofworks practice, and the hard nut to crack on long-term puzzlement building circle is roof leakage and these two problems of heat-insulating property decay.And these two problems are because heat insulating material globality difference causes water space or steam detention space bigger; Look for sloping material moisture content part too high, roofing to leak simultaneously and winter the temperature difference cause in dewfall etc. all will make the steam increase waterproofing course under; Even the waterproofing course maintenance is good again, the waterproofing materials quality is high again, also can't resist " bulge " and the destructions such as frost heave in winter like summer; Cause maintenance every year, the vicious circle phenomenon of every year leaking.When insulation layer was in the water saturation state, roofing not only can not be incubated in the winter time, will look for slope and heat insulating material to be frozen in tightly on the floor on the contrary, formed very big frost-heave force, the destruction of causing agent structures such as cracks on floor slab, wall crazing.Therefore, how to solve the key issue that interior dewfall phenomenon of roofing heat-insulating layer and moistureproof problem have become the roof heat insulation technology.
On the other hand, in roofworks, the roof leakage problem is even more serious, and causes the roof heat insulation performance failure thus.The generation of this problem is except that the quality problems of roof waterproof layer itself, and most important reason is that upper and lower cement mortar overcoat of waterproofing course and leveling layer are very easy to cracking, causes waterproofing course to be torn.Simultaneously, sloping layer and insulation layer moisture content and injection water retaining in reservoir are excessive, cause waterproofing course winter " frost heave " and summer " bulge ", also bring out waterproofing course and are destroyed.
In a word; At present China's waterproofing course and insulation layer in roofworks is two separate functional configurations; These two functional layers need cement mortar screeding to falls layer, leveling layer and overcoat that it is bundled together again; Cause mutual harmful effect and destruction between each layer, form vicious circle, this is the hard nut to crack that perplexs the building circle for a long time.
How to seek and invent a kind of material and make it integrate waterproof and heat insulation function, can satisfy simultaneously requirements such as fire prevention in the roofworks, durable and compressive strength again, become the target that the building scientific research personnel pursues for many years.Had patent documentation to propose similar techniques such as foam-in-place polyurethane or hard polyurethane frothing plate in recent years, but all there are serious problems in fire prevention that should technology, durable and compressive strength, particularly because fireproof performance is relatively poor, are banned use of by national correlation department.
