Abstract

The invention provides a polylactic resin composition which mainly comprises the following components expressed in mass parts: 100 parts of a polylactic resin, 1 to 40 parts of a novel phosphorus flame retardant, 0 to 0.8 part of a trickling-down resisting agent, 0 to 40 parts of thermoplastic elastomers, 0.1 to 30 parts of an inorganic filler and 0 to 20 parts of a high-molecular compatibilizer. Compared with the prior art, the polylactic resin composition provided by the invention has the following advantages: (1) flame resistance of a material is improved, the grade of flame resistance of the material is above Grade UL94V-2, and heat resistance of the material is maintained as well; (2) the novel phosphorus flame retardant is employed in the invention to improve flame resistance the material, and no halogen flame retardant is used, which accords with the environmental protection concept of sustained development; and (3) the polylactic resin composition has the characteristic of capacity of rapid crystallization, so the composition can be easily used in manufacturing procedures of common plastic products, processing performance and production efficiency of the products are improved, and production cost is reduced.

Description

【Technical field】

[0001] The present invention relates to a polylactic acid resin composition, in particular to a polylactic acid resin composition which not only improves flame retardancy but also maintains its heat resistance. 【Background technique】

[0002] In recent years, due to the rising awareness of environmental protection in society and the rising price of crude oil, the public has paid more and more attention to the application of non-petrochemical source materials. Therefore, the application of biocomposites made of bioplastics in the plastics industry is quite eye-catching. Among all commercially produced bioplastics, polylactic acid resin (polylactide resin, PLA) is the most extensively researched because of its excellent physical properties and the lowest acquisition cost. From disposable application products such as disposable tableware, packaging film bags, to mid-level application products such as stationery gifts, children's toys, to high-end application ...
