Summary:Integration vacuum Insulation panel (IVIP) is becoming a new thermal insulation structure, which has potential use in passive zero energy building, and could greatly improve the durability and safety of the insulation structure. IVIP was prepared by taking the VIP as the inner layer and the organic/inorganic material as the protective shell. The results showed that the thermal conductivity of IVIP is 5~10mW/m·K, slightly above the relative VIP. IVIP durability has increased by 200%, and the thermal bridge has reduced by 20%. IVIP could work in the range of temperature from -150℃ to 150℃. IVIP has become a safe, reliable, flame retardant and beautiful new type of high-efficiency insulation structure. As soon as the VIP is broken, it is feared that it is bulging to create a risk of falling off. IVIP could be used as the external heat insulation of the outer wall and provides the bright, self-cleaning and beautiful appearance of a similar ceramic tile. IVIP could be used as the heat preservation of the inner wall surface, in particular to the heat preservation of the toilet, and even the floor and the person could walk directly on the upper surface. The relative VIP core material could be made of ultra-fine glass wool or nano-inorganic powder. The relative VIP envelope could be made of aluminum plastic film, no longer glass fiber cloth which increased the cost. Flame retardant, reflecting agent, and water-resistant agent could be added to the protective layer to further improve the thermal insulation performance of the IVIP.
