Description
Technical field
The present invention relates to external wall technical field, particularly a kind of curtain wall facing vacuum thermal insulation plate and preparation method that can reach heat insulating effect.
Background technology
In China, building energy consumption with industrial energy consumption, traffic energy consumption claim three large energy consumption rich anies influential family, energy-saving potential is huge, and building energy saving industry has become the important organic component of energy-conserving and environment-protective industry.Building energy conservation completes mainly through two aspects, and one is reduce building energy consumption, and two is the efficiency of energy utilization improving building energy consumption system.Heat preservation construction material is adopted to be the main path realizing building energy conservation.
In architectural energy saving system, the thermal losses of exterior wall enclosure structure is larger, wherein body of wall portion is maximum, therefore, construction wall reform is most important link in energy-saving building technology with the development of body of wall power-saving technology, and development External Walls Heating Insulation and energy-saving material are then the main implementations of building energy conservation.
Along with the development of society, increasing building consumes a large amount of non-renewable resources and the energy; The building that particularly a large amount of heat insulating effect is bad, not only makes winter heating and the more energy of cooling in summer consumption, also causes a large amount of environment pollutions, incompatible with current advocated low-carbon economy; The insulation way taked building traditionally adds thick wall body, and so not only cost is high, also consumes a large amount of buildings and resources; Along with the development of constructional materials science and technology, wall thermal insulating heat-barrier material gets more and more, but most of material to be all the building resource that consumes many, cost is high, and the insufficient strength of material, and quality is unstable, easily occurs the defect such as hollowing, efflorescence, cracking.In recent years, along with deepening continuously of China's dwelling construction energy conservation, and the improving constantly of energy conservation standard, introduce and develop many novel power-saving technologies and material, vigorously promote the use in housing construction, wherein be applied to the various foamed plastics heat insulating materials of exterior-wall heat insulation, as EPS plate, XPS plate material and polyurathamc sheet material etc. obtain extensive application because of its high insulating effect.
But due to the feature of these materials self and various fire prevention measure and control measures problem, fire is often occurred.In order to live safety, firmly building portion and the Fire-Fighting Bureau under the Ministry of Public Security and jointly having promulgated " civilian construction Surgery therapy and decoration of exterior wall fire prevention temporary provisions " in September, 2009.Specify the housing construction of more than 100 meters, the curtain buildings of the utilities building of more than 50 meters and more than 24 meters must adopt A level incombustible material.A lot of material condition on the verge of being replaced thus.
Many producers or scientific research institution concentrate one's gaze on inorganic material class the sight line of heat insulating material one after another, inorganic heat insulation material has the features such as energy-conservation, profit is useless, low emission in production, and material self has the features such as performance such as not producing volatile harmful material, lightweight, high-strength, sound insulation.Between floors, there is outstanding incubation and thermal insulation function, can significantly reduce building Energy in use, possess every making an uproar, reducing the characteristics such as room air pollution simultaneously.Inorganic heat insulation mortar has that coefficient of thermal conductivity is low, Acclimation temperature scope is wide, fireproof performance good, resistance to feature of waiting so long.Inorganic heat insulation mortar mostly is slurry, directly adds water at the construction field (site) and stirs, easy construction, simple and direct.Current inorganic heat insulation material has become the main flow in market, has been the developing direction of building energy conservation wall heat insulation material.In current insulation market, the inorganic heat insulation material that fire-protection rating can reach national requirements and provincial standard mostly is slurry, and in work progress, thickness is difficult to control, and difficult quality guarantee, performance does not reach final requirement.Although inorganic heat insulation material fireproof performance can be protected, but its density is large, intensity is low, water proofing property is poor etc., and defect limits again its application.
