杜仲是我国特有的天然资源之一分布广泛,树皮是名贵的中药材,树叶中所含的杜仲胶(反—1·4—聚异戊二烯)经过加工可制得硫化高弹性橡胶,某些性能与天然橡胶相似,大量生产可弥补我国天然橡胶资源的不足。为降低杜仲胶的生产成本,提高杜仲加工企业的综合经济效益,我们利用杜仲叶提取杜仲胶后的废渣与6型硬聚氯乙烯树脂共混制得了性能可满足一般建材要求的复合材 Eucommia bark is one of the unique natural resources of our country. The bark is a precious traditional Chinese medicinal material. Eucommia gum (trans-1.4-polyisoprene) contained in the leaves can be processed to produce vulcanized high-elasticity rubber. Some properties similar to natural rubber, mass production can make up for our lack of natural rubber resources. In order to reduce the production cost of Eucommia ulmoides gum and improve the comprehensive economic benefits of Eucommia processing enterprises, we use Eucommia ulmoides leaves extract Eucommia gum and 6 hard polyvinyl chloride resin blends were prepared to meet the requirements of the general building materials composite materials
