Description
Technical field
The invention belongs to technical field of buildings, particularly relate to a kind of polymer mortar and constructional method thereof.
Background technology
External wall heat insulation system is that the lagging material of hydrophobic nature, low-shrinkage is passed through bonding or anchoring, is placed in outside building masonry wall securely, and the method for ornament layer of constructing outside it.According to the materials classification of finishing mucilage, external wall heat insulation system can be divided into cement based and non-cement base two class, and be exposed to the sun performance requriements, structure and the construction technology of material of its response is all different.External wall outer insulation is a kind of building thermal-insulation energy-saving technology widelyd popularize at present; applied widely; with high content of technology, Surgery therapy wraps in the outside of agent structure, can protect agent structure; extend the life-span of buildings; effectively reduce the heat bridge of building, increase the useful space of building, eliminate condensation simultaneously; be conducive to room temperature and keep stable, improve the comfort level of inhabitation.
The common qualitative problems of construction of external wall exterior insulation work has: bonding EPS heat preservation plate material easily occurs displacement, hollowing and comes off; There is hollowing and come off in slurry thermal insulation layer, hollowing and cracking appear in protective layer, occur very soon after construction, or occur after summer and winter temperature circulation change; There is crackle or have the face brick of exterior trim to occur obscission in protective layer, thus affects exterior insulation work apparent mass permanent stability; Exterior insulation work local is mouldy, condense even Cheng Shuan, and this phenomenon the most easily occurs in severe cold and cold district, and high humidity area is also more; Wall heat transfer coefficient does not reach energy conservation standard etc.
Construction reference according to external wall exterior insulation work specifies, Surgery therapy needs weather temperature more than 5 DEG C construction.Within continuous 5 days, stablize when outdoor daily mean temperature and namely enter winter construction lower than 5 DEG C, winter temperature declines, many local temperature are (i.e. subzero temperature) under 5 DEG C, moisture contained by soil, concrete, mortar etc. freezes, the easy embrittlement of material of construction, and for external wall outer insulation engineering, winter construction easily cause thermal insulation mortar easily to be endured cold and affect the intensity of cohesive strength and polymer facing layer mortar thus cause thermal insulation layer to come off, surface layer ftractures.
And for the Northeast owing to affecting by harsh climate, the construction of exterior insulation system phase is short, brings impact to a certain degree to enterprise and owner, reduce the quality of later work, also bring inconvenience to the engineering needing work to tight deadlines winter.
