With the rapid development of metallurgy, construction, machinery manufacturing and petrochemical industry, safety accidents often occur under high-temperature working environment. Therefore, this paper analyses the heat conduction process of thermal protective clothing, according to the analysis of unstable heat conduction process with Conservation of Energy and Fourier’s law, so as to get the distribution of temperatures with the thickness variation of the material layer. Furthermore, we shall fit the relation between temperature and the thickness of the material layer when the heat transfer reaches steady state, and then determine the optimal range of the thickness of the thermal protective clothing material layer with the upper bound being the highest temperature which human can tolerate. And it can be promoted to the fields of fire protection, metallurgy, machinery manufacturing and other high temperature work.
