Lightweight thermal insulation composites with redispersible polymer powder addition

Lightweight thermal insulation composites with different mass percentages of redispersible polymer powder (RPP) addition were prepared and the effects of RPP addition on mechanical properties, water resistance, thermal conductivity and interfacial bonding of lightweight thermal insulation composites were studied and analysed. The results showed that flexural and compressive strength of samples were improved by the addition of RPP due to improvement of pore structure and enhancement of interfacial bonding. Besides, RPP had a positive effect on thermal conductivity and interfacial bonding of lightweight thermal insulation composites.
