Description
Technical field
The present invention relates to a kind of masonry mortar, specifically, relates to a kind of light masonry mortar with heat insulation and preservation that is used for body of wall porous light thermal insulation brick or light heat insulation blocks, belongs to building material technical field.
Background technology
Along with improving constantly that environment protection and save energy are required, the energy-saving heat preserving technology of architectural exterior-protecting construction has become one of important energy-saving building technology approach of China.Energy-conservation, sharp useless heat insulating novel wall material has been obtained the development of advancing by leaps and bounds, and novel energy-conserving materials for walls such as porous light thermal insulation brick or light heat insulation blocks obtain more and more widely application at various non-bearings, bearing wall.But still major part is built light and heat insulating wall bricks by laying bricks or stones with common masonry mortar in the market, and common masonry mortar is generally sand-cement slurry or mixed mortar, and the dry density of this class mortar is generally 1600～1800kg/m
3, thermal conductivity is 0.8～1.10w/mk, and the dry density of light heat insulation blocks is generally 450～950kg/m
3, thermal conductivity is 0.15～0.35w/mk, because both thermal conductivity gaps are bigger, causes whole masonry to have " cold bridge " phenomenon, reaches about 25% by building the power loss that mortar joint causes by laying bricks or stones, does not reach heat preservation effect; And it is also a lot of that the coefficient of shrinkage between the two differs, and whole masonry is affected the intensity of masonry in the drying and watering cycle process, has seriously influenced the quality of whole body of wall.
Heat-insulating masonry mortar of the prior art mainly contains haydite, granular polystyrene and pearlstone etc. by its light skeletal branch.The porcelain granule light weight aggregate thermal insulation mortar, because haydite surface irregularity porous, water regain is big, it is poor to cause newly mixing the haydite mortar working, is difficult for construction; Pearlstone and granular polystyrene light skeletal thermal insulation mortar water-absorbent are big, easily efflorescence, volume receipts mistake rate is big in the slip construction, easily cause the low and hollowing cracking of product later strength, and the granular polystyrene organic materials is inflammable, fire line is poor, high temperature produce obnoxious flavour and ageing-resistant, weathering resistance is low and workability is poor.In addition, all more than 0.4w/mk, though granular polystyrene light skeletal thermal insulation mortar thermal conductivity is lower than 0.25w/mk, its ultimate compression strength is low, generally at 3MPa for the thermal conductivity of haydite and pearlstone light skeletal thermal insulation mortar.Chinese patent literature CN200710025669.6 discloses a kind of energy-saving heat-insulating masonry mortar, and the component prescription and the weight percent of this masonry mortar are: cement 17～23, flyash 15～55; furnace bottom slag 10～55; glass bead 0～25, admixture 0.7～1.2, wooden sodium water reducer 0.05～0.10.Dry density≤the 1600kg/m of the masonry mortar of this patent
3Minimum ultimate compression strength is 2.5MPa, thermal conductivity≤0.24w/mk, though this patent has solved the " cold bridge " problem because of masonry mortar that uses and the big whole masonry that produces of the thermal conductivity gap between porous light thermal insulation brick or the light heat insulation blocks to a certain extent, but the gap between the dry density of the masonry mortar of this patent and porous light thermal insulation brick or the light heat insulation blocks is still bigger, and water-retentivity is relatively poor, and porous light thermal insulation brick or light heat insulation blocks have stronger water-absorbent, therefore, use the masonry mortar of being prepared, have easy dry shrinkage and cracking, easily the moisture absorption and with problems such as the body of wall adhesion strength is low.
Summary of the invention
The objective of the invention is at the above-mentioned existing in prior technology defective and the market requirement, a kind of have good workability, water-retentivity are provided, with body of wall adhesion strength height, on dry-shrinkage deformed, heat conductivility, be close with porous light thermal insulation brick or light heat insulation blocks, can prevent the metope dry shrinkage and cracking and the moisture absorption, satisfy heat insulation, the light masonry mortar with heat insulation and preservation that insulation requires of energy saving building.
