By adopting the acrylic acid rubber powder or PVA with excellent ageing resistance and water-absorbing resistance and designing and optimizing a formula, the prepared light mortar with low heat conduction not only has excellent bonding performance, compressive strength, breaking strength and other performances, but also has excellent ageing resistance and better heat-insulating performance and can be widely applied to heat insulation of a building wall body.
Description
Technical field
The present invention relates to a kind of low heat conduction light mortar; This material have concurrently insulation, heat insulation, do not fire function; The fire-blocking belt that also can be used as simultaneously the alignment material and the exterior wall heat-preserving system of interior wall, dividing wall; And can effectively prevent serial problems such as thermal insulation wall surface hollowing, cracking, fire-protection rating, can be used for the building heat preservation field.
Background technology
A very important measure of building energy conservation is set up insulation energy-saving system to body of wall exactly; The wall thermal insulating energy conserving system of China mainly contains exterior wall internal insulation system, the sandwich thermal insulated system of body of wall and external thermal insulation system at present; Wherein the external-wall external-insulation energy-saving system has become the main flow of wall thermal insulating form with its numerous advantage, and its major advantage is to protect agent structure, prolongs the buildings life-span; The phenomenon of basically eliminate " heat bridge " helps ambient-temp-stable etc.In outer heat preservation system, the used material of thermal insulation layer mainly is styrofoam and extruded sheet etc. at present, and its thermal conductivity is lower, can satisfy the energy-conservation requirement of buildings, and fire-protection rating does not but reach non-combustible requirement.Appearance along with the Ministry of Public Security, Ministry of Construction's " covil construction outer heat preservation system and decoration of exterior wall fire prevention temporary provisions "; Fire protection requirement to associated materials and heat-insulation system further improves; Existing like this styrofoam and extruded sheet and system difficulty reach requirement, need to accelerate the exploitation of novel wall lagging material and heat-insulation system.Research and facts have proved; Low heat conduction light mortar lagging material is the first-selection of present heat insulating material, and be combined into heat-insulation system can satisfy warm geographic energy-conservation requirement such as Xia Redong cryogenic region and Xia Re and other heat-insulation systems the fire-blocking belt requirement is set.
The low heat conduction light mortar has a series of advantage, thereby it is had ready conditions as new lagging material, for example thermal conductivity lower (≤0.070W/ (mK)); Heat insulating effect is also good, the ultimate compression strength height (>=0.20MPa), in present all lagging materials, belong to the non-fire material of mineral-type; Ageing-resistant, chemicalstability good; And site operation can be realized stdn, industriallization, and is easy and simple to handle, and its operating efficiency exceeds several times of other heat preservation construction modes.
But still there is adhesiveproperties in the inorganic heat insulation mortar system that adopts on the existing market, the insufficient shortcomings in aspect such as ultimate compression strength and durability ability.
Summary of the invention
The purpose of this invention is to provide a kind of have good adhesiveproperties, good anti-folding, ultimate compression strength, excellent durability can and the light mortar with high performance and low heat conduction of anti-accumulation of salt in the surface soil property.
For achieving the above object, the present invention provides a kind of light mortar with high performance and low heat conduction, and its raw material in weight part is formed as follows:
