Abstract
The utility model discloses an ultrathin laminated vacuum insulated panel core material. The core material is formed by superposing a plurality of layers of ultrathin glass fiber cotton, the thickness of an ultrathin glass fiber layer is 0.1-2mm, and the glass fiber cotton is prepared from flame cotton, centrifugal cotton or chopped strands or by blending of the flame cotton, the centrifugal cotton and the chopped strands. A vacuum insulated panel prepared from the ultrathin laminated core material is quite excellent in insulation performance as heat conductivity coefficient can be lower than 0.0025W/(m K), and the ultrathin laminated vacuum insulated panel core material is a novel core material most prominent in heat conductivity coefficient in the vacuum insulated panel core material development history.
Description
Technical field
The utility model relates to a kind of core material of vacuum heat insulation plate, specifically relates to a kind of superthin laminated core material of vacuum heat insulation plate.
Background technique
Along with the progress of science and technology and the reinforcement of social enviroment protection awareness of saving energy, people more and more pay attention to making and the use of heat-insulating heat-preserving material, and the thermal insulation property of especially emerging to some, environmental protection sandwich material, the research of sound insulation value are more and more deep.
Vacuum heat-insulating plate has advantages of numerous uniquenesses such as the A level is not fired, excellent thermal insulation property, light weight, environmental protection, and vacuum heat-insulating plate is applied to the building heat preservation field, will be significant to energy efficient, protection of the environment.Can core be the support in the vacuum heat-insulating plate, is a kind of porous felt, has high porosity ratio, and can not infinitely be compressed, be to determine to maintain the original state after the vacuum heat-insulating plate gas leakage key of long service.The porous material felt is applied in the vacuum heat-insulating plate, after choke heat-resisting thin film packing, is commonly referred to as core.
The every layer thickness of glass fibre core of producing in the market is about more than 2 mm, formed core material of vacuum heat insulation plate after the stack of multilayer core is difficult for oven dry, often need to be in for a long time lower oven dry of high temperature, water evaporation in the production of guarantee wet method core is evaporated fully, to such an extent as to do not affect the thermal insulation property of vacuum heat-insulating plate.In addition, the vacuum heat-insulating plate of same thickness, if the thinness of every layer of core reduces, then core density can reduce, and means that glass wool content reduces in the core of equal volume, so that the also relative minimizing of point of contact between fiber and the fiber, reduced heat transfer, therefore, its insulation effect of prepared vacuum heat-insulating plate also improves greatly, can reach below 0.0025 W/mK.A kind of ultra-thin lamination core material of vacuum heat insulation plate now is provided.
The model utility content
The purpose of this utility model is intended to overcome the existing technical deficiency of inorganic compounding core, and a kind of superthin laminated core material of vacuum heat insulation plate is provided, and reduces the thermal conductivity of vacuum heat-insulating plate with this.
For realizing that the technological scheme that the purpose of this utility model adopts is: a kind of superthin laminated core material of vacuum heat insulation plate is provided, this core is formed by stacking by the glass fibre cotton of Multilayer ultrathin, wherein glass fibre cotton is cotton by flame or centrifugal cotton or chopped silk or above cellucotton are mixed with and form, and the prepared heat conductivity of vacuum insulation panel of core is lower than 0.0025 W/mK.
Described core is characterized in that described ultra-thin glass layer of fibers is 0.1 ~ 2 mm.
Described core is characterized in that the described stack number of plies is 2 ~ 100 layers.
Described core is characterized in that described flame cotton fiber diameter is 0.3 ~ 8 μ m, and length of staple is 1 ~ 20 mm; Described centrifugal cotton fiber diameter is 1 ~ 10 μ m, and length of staple is 2 ~ 60 mm; Described chopped silk fibre diameter is 5 ~ 20 μ m, and length of staple is 5 ~ 80 mm.
Described core is characterized in that core is compressible, and in vacuum heat-insulating plate, its core compression ratio is 10% ~ 30%.
Effect: the utility model compared with prior art has the following advantages:
(1) the prepared heat conductivity of vacuum insulation panel of composite ultra-thin lamination core of the present invention can be lower than 0.0025 W/ (mk), and heat-insulating property is more excellent than the core material of vacuum heat insulation plate of general thickness;
(2) composite ultra-thin lamination core of the present invention easily dry, energy saving, and the preparation the vacuum heat-insulating plate surfacing.
