In order to solve the new problems in performance and comfort of common high temperature protective clothing, this paper explores the physical characteristics and heat conduction process of a common thermal protective clothing. In the study, a grid heat transfer model is established at high temperature, which is composed of four heat transfer equations constructed with four layers of protective materials. The relationship between temperature distribution and time and space is obtained by solving the temperature distribution. The data curve is drawn, and it is observed that the temperature of this thermal protective suit began to change steadily until it remained unchanged after 1744s at the ambient temperature of 75℃. The thermal conductivity of human model skin is calculated to be 0.0017w /(m·℃), and the temperature distribution table of each material layer is given (table 1), providing important calculation rules and theoretical basis for more advanced design of high-temperature protective clothing.
