Process for preparing thermal resistant easy processed polylactic resin

Abstract

The invention belongs to a manufacturer method for thermal resistant easy to machined poly lactic acid resin that is made up from poly lactic acid, thermal resistant material, high molten mass speed polymers material aliphatic polyester and antioxidant. The process includes mixing in blending machine, and extruding at 160-185 degree centigrade. The resin could be used to make film, panel, sheet material, sparkle, and plastic components. The products have excellent thermal resistance capability, mechanical property and machine property.

Description

Technical field:

[0001] The invention belongs to a preparation method of heat-resistant and easy-processing polylactic acid resin. Background technique:

[0002] The initial raw material for the synthesis of polylactic acid is starch, which is converted into lactic acid through a biological fermentation process, and polylactic acid is obtained from lactic acid through polycondensation or ring-opening polymerization of lactide. It can be seen that one of the essences of polylactic acid different from other general-purpose plastics is that it utilizes renewable plant resources. This can effectively alleviate the increasingly depleted oil resources. Moreover, polylactic acid has exactly the same properties as general-purpose plastics, such as mechanical properties and processability. In particular, the current large-scale production has reduced the cost of polylactic acid resin, making it very cheap compared to other biodegradable polymer materials. Therefore, in recent year...
