Abstract

A polylactic acid resin composition contains a polylactic acid resin having an epoxy group, and a flame-retardant additive.

Claims (6)

1. A method for producing a polylactic acid resin composition comprising:

kneading a polylactic acid resin, a flame-retardant additive, and a hydroxy-epoxy compound represented by general formula (1):

wherein R represents a linear alkylene group, branched alkylene group, arylene group, or arylalkylene group having 1 to 10 carbon atoms.

2. The method according to claim 1 , wherein the amount of the hydroxy-epoxy compound is about 1 part by weight or more and about 10 parts by weight or less relative to 100 parts by weight of the polylactic acid resin.

3. The method according to claim 1 , wherein the amount of the flame-retardant additive is about 2 parts by weight or more and about 300 parts by weight or less relative to 100 parts by weight of the polylactic acid resin.

4. The method according to claim 1 , wherein the amount of the flame-retardant additive is about 10 parts by weight or more and about 200 parts by weight or less relative to 100 parts by weight of the polylactic acid resin.
