The research and development background of thermal insulation materials:
the traditional thermal insulation material is to improve the air gap rate, reduce the thermal conductivity and conduction coefficient. In order to increase the convective heat transfer and radiation heat transfer in the use of fiber insulation materials, we must have thicker cladding. The construction of profile inorganic insulation materials should have many defects, such as many joints, beautiful appearance, poor waterproofing and short service life. To this end, people have been seeking and studying a new type of material which can greatly improve the heat insulation and reflective properties of thermal insulation materials.
