### A FRACTIONAL MODEL AND ITS APPLICATION TO HEAT PREVENTION COATING WITH COCOON-LIKE HIERARCHY

**ABSTRACT**

In this paper, a fractional model is established by using the variational iteration method to elucidate the thermal properties of building prevention coating with a cocoon-like hierarchy. The fractal hierarchical structure of heat prevention coating makes the building wall mathematically adapted for an extreme temperature environment. This work has inspired the bionic design of protective suits and extreme temperature clothing.
