Description
Technical field
The present invention relates to a kind of soy-protein/polyvinyl alcohol blending material and preparation method thereof, belong to polymeric material field.
Background technology
Since 21 century, the widespread use of plastics has caused serious problem of environmental pollution, directly threatens the mankind's Sustainable development.Therefore, the research of the natural macromolecular material based on renewable resources and application are extremely paid attention to.Soy-protein is the byproduct of soya-bean oil industry, its wide material sources and output are abundant, cheap, and there is good biological activity and biodegradability, be mainly used at present the field (Kumar such as wrapping material, degradable plastic product, environmental protection tamanori and foodstuffs industry, R.Ind Eng Chem Res2010,49,3479 – 3484).Conventionally, true protein material enbrittle, the shortcoming such as poor mechanical property.Mainly improve its mechanical property by physics or chemical modification at present, as add small molecules softening agent, increase protein toughness and intensity (Tian, H. with the method such as other are polymer blended, acidylate; Wang; Y., Zhang, L.; Quan; C., Zhang, X.Ind Crop Prod2010; 32,13 – 20).
Polyvinyl alcohol is a class petroleum base biodegradable material, has good mechanical property.By polyvinyl alcohol and the natural polymer blended feature of improving a little less than natural polymer mechanical property.But, at present, polyvinyl alcohol and the multiplex solution casting method of natural polymer blended material (Su J, Yuan X, Huang Z, Xia W, Polym Degrad Stab2010,95,1226), expend a large amount of water, have the shortcomings such as energy consumption is high, pollution is large, efficiency is low.Therefore be necessary to develop the processing for polyvinyl alcohol/natural polymer blended material of a kind of novel, low cost and eco-friendly method.
Summary of the invention
The object of this invention is to provide a kind of soy-protein/polyvinyl alcohol blending material and preparation method thereof, this material has good mechanical property and water tolerance, and preparation technology is simple, and process environmental protection is with low cost.
