Description
Technical field:
The present invention is the heat insulation field of building heat preservation
Background technology:
Extruded sheet conventional heat-insulation systems such as (polyphenyl plate) is used in combination to reach and not only is incubated but also heat insulation energy-saving effect, but cost is higher, fire prevention is poor, construction sequence is loaded down with trivial details, shortcoming such as long in time limit.Shortcomings such as adhesive polystyrene granule heat-insulating system and inorganic heat insulation mortar system come off owing to the difficult construction of the thicker existence of smearing thickness reaches easily, the thickness to heat preservation slurry in practical applications has certain restriction.
Summary of the invention:
The thermal insulation mortar coefficient of thermal conductivity is less than 0.1W/ (mK), and when improving the thermal insulation mortar heat-insulating property, the intensity of thermal insulation mortar is but descending.And coefficient of thermal conductivity can improve the intensity of mortar greater than 0.1 lightweight screed, and the compressive strength of lightweight screed can reach M2.5, M5.0 even higher.And the lightweight screed coefficient of thermal conductivity is 0.1～0.25W/ (mK), in energy conservation project, is difficult to get the nod.Use lightweight screed to be difficult to pass through energy saving calculation separately.
It is thicker that heat preservation slurries such as adhesive polystyrene granule heat-insulating mortar, gypsum insulation mortar, inorganic heat insulation mortar, heat preservation putty are smeared thickness, shortcoming such as come off easily, and the thickness of doing heat preservation slurry in practical applications all has certain restriction.
For overcoming the prior art defective, the invention reside in a kind of compound insulation system of being made up of heat preservation slurries such as lightweight screed and adhesive polystyrene granule heat-insulating mortar, gypsum insulation mortar, inorganic heat insulation mortars is provided.
Novelty of the present invention is that the combination of lightweight screed and heat preservation slurry can reduce the thickness of heat preservation slurry, has overcome relatively poor, the shortcoming such as come off easily of the thicker workability of heat preservation slurry thickness.
Compared with prior art, the characteristics of this patent are:
1, lightweight screed promptly can also have certain heat insulation effect as the leveling layer of building.Lightweight screed combines to reach the energy conservation standard of building 50%～65% with heat preservation slurry.
2, cancelled sheet material class heat-insulation system, can improve programming.
3, simple structure of the present invention, energy-conservation reasonable.Has the fire prevention of A level, the characteristics that cost is low, the duration is short.
4, generally between 0.1～0.25, thermal conductivity ratio is higher for the lightweight screed coefficient of thermal conductivity, is used in architecturally separately, is difficult to reach the energy saving calculation requirement.Therefore conventional heat-insulation system is not considered the effect of lightweight screed in insulation.If lightweight screed is used in combination with heat preservation slurry, then can reach the energy saving calculation requirement, can reach the optimality price ratio.
