Resin composition, resin compact, production method of resin compact and recycling method of resin compact
View Patent ↗A resin composition, includes: an aliphatic polyester; a second polymer compound having a glass transition point higher than a glass transition point of the aliphatic polyester; and aluminum phosphate.
1. A resin composition, comprising:
an aliphatic polyester;
a second polymer compound having a glass transition point higher than a glass transition point of the aliphatic polyester;
aluminum phosphate; and
an elastomer having a core-shell structure with the core comprising butadiene and the shell comprising acryl.
2. The resin composition according to claim 1 , wherein a ratio A/B between a mass A of the aliphatic polyester and a mass B of the second polymer compound is from 0.3 to 1.1.
3. The resin composition according to claim 1 , wherein the aliphatic polyester is polylactic acid.
4. The resin composition according to claim 1 , wherein the second polymer compound is polycarbonate.
5. A resin compact, comprising the resin composition according to claim 1 .
6. The resin compact according to claim 5 , comprising a fibrous aliphatic polyester phase.
7. A method for producing a resin compact, comprising:
injection-molding the resin composition according to claim 1 under a condition of allowing a temperature of the resin composition to become 230° C. or less.
8. A method for recycling a resin compact, comprising:
grinding the resin compact according to claim 5 ;
heating a ground product obtained in the grinding at a temperature lower than a melting point of the aliphatic polyester; and
shaping the ground product after the heating to obtain a resin compact.
9. The method according to claim 8 , wherein the grinding is freeze-grinding the resin compact and the shaping is injection-molding the ground product after the heating to obtain a resin compact.
