摘要

Four kinds of agricultural wastes particles (XS: oilseed rape straw [OS], rice straw [RS], wheat straw [WS], and corn stover [CS]) were used to reinforce agricultural wastes liquefied polyol (P-XS) based polyurethane (PU) foam. Different XS loading dosages (0% similar to 15%) are investigated to confirm suitable filler concentrations for modifying foams. RS particles show great promoting ability, OS particles reveal complex influence, while WS and CS particles display mild effect on foaming process. With 1% of OS, 6% of RS, 3% of WS, or 1% of CS incorporating in matrix materials, the reinforced foam could keep applicable density, reach better physical and mechanical property, display more uniform cellular structure, and show higher thermal stability with more excellent water absorption ability. Using of agricultural wastes as polymer filler is economical, simple, environmental, and wide applicable for biomass utilization and biopolymer preparation.
