摘　　要：Environment friendly thermosetting composites were prepared by blending wheat gluten （WG） and rice protein （RP） at different weight ratios with glycerol as plasticizer followed by compression molding the mixture at 120℃ to crosslink the proteins. Reducing agent of sodium bisulfate and sodium sulfite and crosslinking agent formaldehyde were used to adjust the properties of the composites. Morphology, moisture absorption and tensile properties were evaluated. The results showed that formaldehyde could increase tensile strength of the composites without significant influence on Young＇s modulus and elongation at break. On the other hand, reducing agents could improve tensile strength and extensibility simultaneously, which was much marked at WG/RP ratios from 7/3 to 3/7.Environment friendly thermosetting composites were prepared by blending wheat gluten （WG） and rice protein （RP） at different weight ratios with glycerol as plasticizer followed by compression molding the mixture at 120℃ to crosslink the proteins.
