PROBLEM TO BE SOLVED: To provide a resin composition having flame retardancy and having excellent mechanical strength in tensile fracture elongation, with the use of a polylactic acid resin and a halogen-containing epoxy modified entity.SOLUTION: A fireproofing polylactic acid resin composition obtained by mixing (A) a polylactic acid resin and (B) 5-15 pts.wt. plasticizer having two ester groups in a molecule, in which an alcohol component comprising the ester is obtained by adding 0.5-5 mol ethylene oxide per one hydroxide group in average, (C) 0.1-3 pts.wt. crystal nucleating agent containing a compound having a hydroxide group and an amide group in the molecule and a phenyl sulfonic metal salt, (D-1) 5-50 pts.wt. halogen-containing epoxy modified entity expressed by general formula (1), having a number average molecular weight of 500-1,500 and (E) 1-20 pts.wt. antimony compound is used ( in the formula, each of Rand Ris independently glycidyl group, hydrogen atom or 2-hydroxy-3-(substituted) phenoxy propyl group) to 100 pts.wt. polylactic acid resin. |
