Abstract

The invention provides a heat-resistant polylactic acid blend and a preparation method thereof, pertaining to the polymer materials technique field, solving the problems of bad heat-resistant performance, weak mechanical performance and being not to be biodegraded, etc. The heat-resistant polylactic acid blend consists of the following components according to weight proportion: 100 parts of polylactic acid, 5 parts to 100 parts of heat-resistant polymer materials which can be biodegraded, 0 to 100 parts of fillers; the preparation method is that: A. blending; B. banburying; C. hot pressing forming; D. isothermal crystallization. The heat-resistant polylactic acid blend of the invention uses the polylactic acid which has a synergistic effect between crystallization and heat-resistant components, and therefore the invention has good heat-resistant performance. The invention adopts various components matching use, so the blend can not only be biodegraded, but also has good mechanical performance; the whole preparation method has simple technical process, good processing performance, low cost and can realize large-scale and industrialized production.

Description

technical field

[0001] The invention relates to a polyester composite material and a preparation method thereof, in particular to a heat-resistant polylactic acid blend and a preparation method thereof; belonging to the technical field of polymer materials. Background technique

[0002] The negative impact of waste of polymer materials on the environment has aroused people's widespread concern, and solving the increasingly serious "white pollution" problem has become a common concern of people. Therefore, the research and development of degradable plastics at home and abroad are very active, and some of them have started industrial production, and the development is quite rapid. Biodegradable plastics not only have the excellent performance of the plastic itself when used, but also do not pollute the environment when discarded after use, and can be quickly decomposed by various organisms (enzymes). Therefore, vigorously developing and promoting biodegradable polymer materia...
