Abstract

Lightweight thermal insulation composites with different mass percentages of expanded polystyrene (EPS) were prepared, and the effects of Polypropylene fiber (PPF) and redispersible polymer powder (RPP) addition on mechanical properties of lightweight thermal insulation composites were investigated. The results indicated that the density, thermal conductivity, flexural and compressive strength of lightweight thermal insulation composites significantly decreased with the increase of EPS. Besides, PPF and RPP both had a positive effect on the mechanical properties of lightweight thermal insulation composites.
