Abstract

A resin composition includes a polylactic acid resin or cellulose resin, 0.07 phr to 8 phr of lignin, and 4 phr to 30 phr of an aromatic condensed phosphoric acid ester.

Claims (24)

1. A resin composition comprising:

a polylactic acid resin or cellulose resin,

0.07 phr to 8 phr of lignin, and

4 phr to 30 phr of an aromatic condensed phosphoric acid ester,

wherein a weight-average molecular weight of the lignin is in a range of from 5000 to 10000.

2. The resin composition according to claim 1 , wherein a weight ratio of the lignin to the aromatic condensed phosphoric acid ester is in a range of from 1:1 to 1:200.

3. The resin composition according to claim 1 , wherein an amount of the aromatic condensed phosphoric acid ester is from 5 phr to 20 phr.

4. The resin composition according to claim 1 , wherein an amount of lignin is from 0.1 phr to 5 phr.

5. The resin composition according to claim 1 , wherein a content of the polylactic acid resin or cellulose resin is in a range of from 72% by weight to 95% by weight, based on the total resin composition.

6. A resin composition comprising:

a crosslinked polymer compound formed from a polylactic acid resin or cellulose resin and 0.07 phr to 8 phr of lignin, and

4 phr to 30 phr of an aromatic condensed phosphoric acid ester.

7. The resin composition according to claim 6 , wherein an amount of lignin is from 0.1 phr to 5 phr.

8. The resin composition according to claim 6 , wherein a weight ratio of the lignin to the aromatic condensed phosphoric acid ester is in a range of from 1:1 to 1:200.

9. The resin composition according to claim 6 , wherein an amount of the aromatic condensed phosphoric acid ester is from 5 phr to 20 phr.

10. The resin composition according to claim 6 , wherein a weight-average molecular weight of the lignin is in a range of from 5000 to 10000.

11. The resin composition according to claim 6 , wherein a content of the polylactic acid resin or cellulose resin is in a range of from 72% by weight to 95% by weight, based on the total resin composition.

12. A resin molded article comprising:

a crosslinked polymer compound formed from a polylactic acid resin or cellulose resin and 0.07 phr to 8 phr of lignin, and

4 phr to 30 phr of an aromatic condensed phosphoric acid ester.

13. The resin molded article according to claim 12 , wherein an amount of lignin is from 0.1 phr to 5 phr.

14. The resin molded article according to claim 12 , wherein a weight ratio of the lignin to the aromatic condensed phosphoric acid ester is in a range of from 1:1 to 1:200.

15. The resin molded article according to claim 12 , wherein an amount of the aromatic condensed phosphoric acid ester is from 5 phr to 20 phr.

16. The resin molded article according to claim 12 , wherein a weight-average molecular weight of the lignin is in a range of from 5000 to 10000.
