麦秸/塑料复合材料的热反应特征及复合工艺

本研究用差示扫描量热法(DSC)测定和分析了麦秸/塑料复合材料的热反应特征，并通过试验探讨了麦秸与塑料之间的复合工艺。结果表明，麦秸、塑料以及麦秸/塑料复合材料三者的热反应特征各不相同，由此可了解麦秸和塑料之间的反应状况，说明用麦秸和塑料制造麦/塑复合材料是可行的。

A Study on Hot-Reaction Characteristics and Technology for Wheat Straw-Plastic Composites

For expanding a new way to use wheat straw, the authors conducted an orthogonal (experiment) in order to determine the feasibility of making wheat straw-plastic composites. In this (paper,) the hot-reaction characteristics of wheat straw, plastics (PE, PVC, EVA) and three kinds of wheat straw-plastic composites were examined by Differential Scanning Calorimetry method (DSC). DSC curves of the monomer and composite materials revealed the distinctions between them, which indicated that some chemical reactions had happened between the wheat straw and the plastic. The paper further analyzed the effects of experimental factors, such as the plastic types, size of wheat straw powder and the ratio of wheat straw to plastic, on the tensile strength of the composite. These results provided references for researching technology for wheat straw-plastic composites.
