摘要

This paper studied the long-term thermal insulation performance of polystyrene foam boards with the decay of blowing agents. A transient cell-to-cell diffusion model was developed to predict the decay of blowing agents. The Mie Theory was used to quantify the radiative conductivity. A cubic-parallel-series analogy of electric circuit was employed to acquire the thermal conductivity of gaseous phase and polymer matrix. Thus, the thermal insulation performance was estimated as the blowing agents decayed. The effects of foam morphology and blowing agent type on thermal insulation capacity were examined.
