Embodiment 1 to 13 and comparative example 1 to 4

[0117]Under the conditions of the composition and cylinder temperature shown in Table 1 and Table 2, polylactic acid resin, a compound containing a single epoxy group, and a flame-retardant The compounds were kneaded to prepare polylactic acid resin composition particles (Examples 1 to 13). For comparison, under the conditions of the composition and cylinder temperature shown in Table 2, pellets of resin compositions not containing the monoepoxy group-containing compound were prepared (Comparative Examples 1 to 4).

[0118] Next, the above-mentioned polylactic acid resin composition pellets were used to form an ISO multi-purpose dumbbell-shaped sample (thickness: 4mm, width: 10mm, according to ISO527 tensile test and ISO178 bending test). Polylactic acid resin moldings were subjected to performance tests (Examples 1 to 13) in accordance with the methods described below. In addition, using the resin compositions of Comparative Examples 1 to 4, samples were molded in a similar ...

Abstract

A polylactic acid resin composition contains a polylactic acid resin with an epoxy group and a flame retardant additive.

Description

technical field [0001] The present invention relates to a polylactic acid resin composition, a method for producing the polylactic acid resin composition, and a polylactic acid resin molded article. Background technique [0002] In recent years, various applications of resin molded articles using biodegradable resins have been studied from the viewpoint of environmental protection. Among these uses, in the field of housings for electronic products and the like, the above-mentioned resin molded articles are required to have flame retardancy. For example, Japanese Unexamined Patent Application Publication No. 2009-144075 discloses a resin composition in which polylactic acid, which is one of aliphatic polyesters, is blended with a phosphorus-based flame retardant and the like. Japanese Unexamined Patent Application Publication No. 2008-019294 discloses a flame-retardant polylactic acid resin composition containing, as main components, a polylactic acid resin, a methacrylate c...
