Resin composition and resin molded article
View Patent ↗A resin composition includes a polylactic acid, a monocarbodiimide compound and a phosphazene.
1. A resin composition, comprising:
a resin, wherein the resin present in the resin composition is only a polylactic acid and an acrylic rubber material, and a content of the acrylic rubber material is from 3% by mass to 15% by mass on the basis of a whole amount of solids of the resin composition;
a carbodiimide compound, wherein the only carbodiimide compound present in the resin composition is a monocarbodiimide compound and a content of the monocarbodiimide compound is from about 1% by mass to about 5% by mass on the basis of the whole amount of solids of the resin composition;
a phosphazene compound, wherein a content of the phosphazene compound is from about 5% by mass to about 50% by mass on the basis of the whole amount of solids of the resin composition; and
a flame retardant having a melting temperature of about 200° C. or higher.
2. The resin composition according to claim 1 , wherein the flame retardant is a phosphoric acid salt compound.
3. The resin composition according to claim 1 , wherein a content of the polylactic acid is from about 30% by mass to about 90% by mass on the basis of the whole amount of solids of the resin composition.
4. The resin composition according to claim 1 , wherein a content of the flame retardant is from about 5% by mass to about 50% by mass on the basis of the whole amount of solids of the resin composition.
5. A resin molded article, comprising:
a resin, wherein the resin present in the resin molded article is only a polylactic acid and an acrylic rubber material, and a content of the acrylic rubber material is from 3% by mass to 15% by mass on the basis of a mass of a whole of the resin molded article;
a carbodiimide compound, wherein the only carbodiimide compound present in the resin molded article is a monocarbodiimide compound and a content of the monocarbodiimide compound is from about 1% by mass to about 5% by mass on the basis of the mass of the whole of the resin molded article;
a phosphazene compound, wherein a content of the phosphazene compound is from about 5% by mass to about 50% by mass on the basis of the mass of the whole of the resin molded article; and
a flame retardant having a melting temperature of about 200° C. or higher.
6. The resin molded article according to claim 5 , wherein the flame retardant is a phosphoric acid salt compound.
7. The resin molded article according to claim 5 , wherein a content of the polylactic acid is from about 30% by mass to about 90% by mass on the basis of the mass of the whole of the resin molded article.
8. The resin molded article according to claim 5 , wherein a content of the flame retardant is from about 5% by mass to about 50% by mass on the basis of the mass of the whole of the resin molded article.
9. The resin molded article according to claim 5 , which is a part of electronic or electrical instrument.
10. A resin composition consisting essentially of:
a resin that is only a polylactic acid and an acrylic rubber material, wherein a content of the acrylic rubber material is from 3% by mass to 15% by mass on the basis of a whole amount of solids of the resin composition;
a monocarbodiimide compound in a content of from about 1% by mass to about 5% by mass on the basis of the whole amount of solids of the resin composition;
a phosphazene compound in a content of from about 5% by mass to about 50% by mass on the basis of the whole amount of solids of the resin composition;
a flame retardant having a melting temperature of about 200° C. or higher; and
optionally a drip preventing agent.
