Description
Technical field
The present invention relates to the building energy conservation heat insulation field, refer to especially a kind of body of wall vacuum heat-insulation plate and preparation method thereof.
Background technology
Vacuum heat-insulating plate (Vacuum Insulation Panel, be called for short VIP) be a kind of super heat-insulating material, the method that employing vacuumizes extracts the gas in adiabatic space, make the various heat transfer paths that wherein cause because of gas weaken, even eliminate, play effective heat shield effect, thereby make its insulation effect be much better than the conventional insulation material.
The development of construction of 21st century will reduce discharging with building energy conservation attaches most importance to, and adheres to that energy-saving and emission-reduction combine with scientific and technical innovation.One of measure that building energy conservation is main is that to be widely used coefficient of thermal conductivity low and satisfy the insulating product of related request.Take the lead in using vacuum heat-insulating plate in energy saving building in some developed countries of Europe in recent years, be particularly useful for the energy saving building that the cold district insulation is had relatively high expectations.It is estimated, in European Union member countries, if adopt VIP heat insulating material, only this item, building CO on the Energy Saving of the reducing energy consumption of old building and new building
2Discharge value just can reduce by 8%.In addition, minimum, consumptive material recoverable, thereby VIP again of insulation layer thickness also will be economized than general heat insulating material; the development and application insulating board for building; can be energy-efficient, can save a large amount of resources again, this to promote building trade intensive, environmental protectionization is significant.
But, in prior art, caused vacuum to descend because VIP specific complex barrier bag very easily galls or is punctured, and existing VIP specific complex barrier bag be difficult for bonding with body of wall, to install and use condition harsher, and can not directly apply to the energy saving building field.
Summary of the invention
