Abstract

In order to overcome moisture absorption of straw based composite with poly(vinyl alcohol) as adhesive material, poly(vinyl acetate) (PVAC) was introduced into the preparation of composite based on rice straw slice (RSS). The effects of PVAC content, hot-pressing temperature and hot-pressing time on the performances were studied. Results showed that tensile strength of composite increased with the increases of PVAC content and hot-pressing temperature, and decreased with the increase of hot-pressing time. The tensile strength of composite arrived at 8.34 MPa when PVAC content was 50%, hot-pressing temperature was 170 and hot-pressing time was 14 min. Tensile elongation of composite increased with increasing PVAC amount. When PVAC contents were 17% and 50%, tensile elongations were 13.5% and 20.9% respectively. The increasing rate was 54.9%. Tensile elongation was higher than elongation at maximum tensile force. This indicated that PVAC/RSS composite had certain toughness.
