Description
Technical field
This utility model relates to a kind of building heat preservation fire proofing material, and the aerogel foam particularly relating to a kind of band decorative cover mixes
Solidifying soil insulated fire plate, belongs to the fields such as lightweight, thermal insulation, fire prevention, deadener.
Background technology
Along with the progress of society, the problem such as energy crisis, ecological deterioration is on the rise.2006, " national economy and society
Development 11th Five-Year Plan outline " " energy-saving and emission-reduction " concept is proposed first, it is proposed that the Eleventh Five-Year Plan period (2006-2010
Year) energy consumption per unit reduction about 20%, total emissions of major pollutants reduces by the binding indicator of 10%." joint
Can " promotions " reduce discharging ", at home in production total energy consumption, building energy consumption accounts for 33%, and building energy conservation is the weight of China's energy-saving and emission-reduction cause
In weight.According to statistics, the heat loss of wall body structure is relatively the highest, and it is the key of building energy conservation that body of wall is taked heat insulation measure
Step.
Conventional wall heat insulation material has expanded polystyrene (EPS), polyurathamc, rock wool, thermal insulation mortar, foamed glass, biography
System foam concrete etc..Expanded polystyrene (EPS) and polyurathamc heat-proof quality are excellent, but it is met, and fire is inflammable, produce asphyxiating
Smog, serious threat owner's safety；Rock wool heat-proof quality is excellent, but meets water and lost efficacy, and difficulty of construction is big；Thermal insulation mortar is prevented fires
Performance is good, but heat conductivity is of a relatively high；Foamed glass easily falls slag, relatively costly, affects its engineer applied.
Compared with existing insulation material, foam concrete belongs to A level insulation material, and it is excellent to have intensity height, low cost etc.
Gesture, but, its heat preservation and insulation is not as good as organic foam insulation material.Therefore, the thermal insulation separation of foam concrete is improved further
Hot property is significant.
Aeroge is a kind of light-weight inorganic solid material with three-dimensional network framing structure and nanoscale hole, has pole
High porosity, specific surface area, extremely low density and solid content, chemical inertness and noninflammability, show the lightweight of excellence, insulation
The characteristics such as heat insulation, fire prevention, sound insulation, damping energy-absorbing, heat conductivity can as little as 0.013W/m K.Therefore, if aeroge is added to
Foam concrete is expected to break through restriction and improves the bottleneck of foam concrete heat preservation and insulation further.
But, in the aerogel foam concrete heat-insulating PLASTIC LAMINATED of research and development band decorative cover, run into techniques below bottleneck: (1)
Owing to aerogel powder is big with concrete density difference, in mixed process, phenomenon of phase separation the most easily occurs, causes
Aeroge is difficult to be evenly distributed in concrete system, causes foam concrete mechanical property degradation, and heat-insulating property carries
High inconspicuous；(2) in foam concrete preparation process, aeroge nano-porous structure is easily by the water in concrete and cement
Additives in raw material etc. destroy, and lose the excellent heat-insulating property that aeroge brings because of nano-porous structure feature；(3) airsetting
Usually because boundary strength is low between glue and Binder Materials, cause foam concrete mechanical property to significantly reduce, and be easily caused
Aerogel powder comes off from concrete substrate, has a strong impact on the engineer applied of foam concrete；(4) aerogel foam concrete
Between plate and finish coat, boundary strength is relatively low, finish coat easily occur hollowing, ftracture, the phenomenon such as come off.
