总结了高分子材料加工的发展趋势及发展历程,并指出过去很多加工新技术的出现都得益于从自然现象及其他材料行业中获得很好的借鉴,如从蜘蛛吐丝发展出溶液纺丝成型、从玻璃吹制发展出吹塑成型、从金属锻造发展出压延成型及固相拉拔成型等;随后针对生物基可生物降解的立构复合型聚乳酸难以采用传统熔融加工方法成型的问题,借鉴金属粉末冶金加工的思路,提出了一种通过低温烧结制备高性能立构复合型聚乳酸制品的新方法.通过这种加工方法不仅可以有效解决立构复合型聚乳酸在熔融加工过程中熔体稳定性差、易降解的问题,而且可以制得耐热性好、光学透明度高、耐水解降解性佳、综合力学性能优异的高性能聚乳酸制品.
Summarizes the development trend and development process of polymer materials processing and points out that in the past a lot of new processing technologies have benefited from the good use of natural phenomena and other materials industries, such as spinning spider silk to develop solution spinning Forming, from the blown glass developed blow molding, from the development of metal forging rolling forming and solid state drawing, etc .; then biodegradable biodegradable stereocomplex polylactic acid difficult to use the traditional melt forming method of forming problems , Drawing on the idea of metal powder metallurgy processing, a new method of preparing high-performance stereocomplex polylactic acid product by low temperature sintering is proposed.It can not only effectively solve the problem that during the process of melt processing of stereocomplex polylactic acid Melt stability is poor, easy to degrade, and can be prepared with good heat resistance, high optical transparency, hydrolysis resistance and good comprehensive mechanical properties of high performance polylactic acid products.
