Description
Technical field
The present invention relates to a kind of inorganic composite materials core and preparation method thereof, particularly relate to inorganic composite materials core that a kind of ultra-fine fibre glass and zeolite granular mix and preparation method thereof.
Background technique
In recent years, along with coming of global energy crisis, the whole society has proposed harsher requirement to heat-insulating heat-preserving material.The applications such as particularly, construction wall insulation, refrigerator-freezer, naval vessels (boats and ships) require heat-insulating heat-preserving material not only to have low thermal conductivity also must possess the characteristic that A1 level is not fired.Vacuum heat-insulating plate has excellent insulation heat-insulating property, and thermal conductivity can be low to moderate 0.003W/ (mK), and does not contain any ODS material, has environmental protection and energy-efficient characteristic, is also state-of-the-art thermal insulation material in the world at present.Vacuum heat-insulating plate is applied in the fields such as building, white domestic appliances, can reaches 10%～40% fractional energy savings, and increase actual volume 20%～30%.
Core material of vacuum heat insulation plate, as the support of vacuum heat-insulating plate, is also the core texture of vacuum heat-insulating plate.It also affects the heat-insulating property of vacuum heat-insulating plate to a great extent.Therefore, core material of vacuum heat insulation plate not only will possess good intensity, and also needing has good thermal and insulating performance.At present, core material of vacuum heat insulation plate is mainly to take super glass wool as main.But the core material of vacuum heat insulation plate surface irregularity consisting of glass wool completely, intensity is not high, thermal conductivity is unstable, rebound degree is also high, can not be applied in some special dimension, has limited its development.For solving this difficult problem, there is on the market the inorganic composite materials core of the confusions such as some super glass wools and calcium silicate particle and/or silica dioxide granule and/or perlite and/or gesso and/or calcium carbonate granule and/or pearlife and/or glass bead.But these core performance improvement degree are not high.In addition, these inorganic composite materials cores are in drying course, and the atmosphere of core inside, especially water vapour are not easy to be evaporated, cause the inner residual excess moisture of core material of vacuum heat insulation plate after encapsulation, had a strong impact on heat-shielding performance and the working life of vacuum heat-insulating plate.At present, only have by improving bake out temperature, extending drying time or add more siccative and realize the object of fully dry core material of vacuum heat insulation plate to the way in vacuum heat-insulating plate.But this way has strengthened energy consumption, can not realize the original intention of energy-saving and emission-reduction.
