增塑剂对大豆蛋白质塑料吸水率的影响

The Effect of Plasticizers on Water Absorption of Soy Protein Plastics

大豆蛋白质作为生物降解天然高分子材料的代表,加入一定量的增塑剂之后具有良好的加工性能、力学性能和生物降解性。另外,吸水性对其性能的发挥又有很大影响。本实验采用多种增塑剂对大豆蛋白质进行增塑,观察了增塑剂对大豆蛋白质塑料吸水率的影响,并对其吸水率进行了对比。

After adds a certain amount plasticizer in Soybean protein as a representative of the biodegradable natural polymer materials,it has good processability,mechanical property and biodegradability. In addition,the hydroscopicity has a great influence on the full play of its performance. This paper used several kinds of common plasticizers to plasticize soybean protein,then,testing its water absorption and comparing the consequences.
