Abstract

Provided are a thermoplastic resin composition including a thermoplastic resin and an amorphous sheet-shaped metal particle having a ratio of thickness relative to long diameter of about 1:20 to about 1:1, and a molded product using the same.

Claims

1. A thermoplastic resin composition, comprising

a thermoplastic resin;

an amorphous sheet-shaped metal particle having a ratio of thickness relative to long diameter of about 1;

20 to about 1;

1; and

a sparkling particle having a flat surface reflecting light,

wherein the sparkling particle comprises a metal particle having a ratio of thickness relative to a long diameter of about 1;

10 to about 1;

1 obtained by punching and an inorganic particle in a weight ratio of the metal particle to the inorganic particle of about 1;

10 to about 10;

1.

2. The thermoplastic resin composition of claim 1, wherein the thermoplastic resin comprises a polycarbonate resin, a rubber modified vinyl-based copolymer resin, a polyester resin, a polyalkyl(meth)acrylate resin, or a combination thereof.

3. The thermoplastic resin composition of claim 1, wherein the amorphous sheet-shaped metal particle is made of a material including aluminum, copper, gold, or a combination thereof.

4. The thermoplastic resin composition of claim 1, wherein the amorphous sheet-shaped metal particle has a ratio of thickness relative to long diameter of about 1:

15 to about 1;

2.

5. The thermoplastic resin composition of claim 1, comprising the amorphous sheet-shaped metal particle in an amount of about 0.05 to about 10 parts by weight based on about 100 parts by weight of the thermoplastic resin.

6. The thermoplastic resin composition of claim 1, wherein the metal particle obtained by punching is made of a material including aluminum, copper, gold, or a combination thereof.

7. The thermoplastic resin composition of claim 1, wherein the inorganic particle comprises a glass particle, mica, graphite, a pearl particle, or a combination thereof.

8. The thermoplastic resin composition of claim 1, wherein the inorganic particle has a long diameter of about 10 to about 200 μ

m and a thickness of about 0.5 to about 10 μ

m.

9. The thermoplastic resin composition of claim 1, wherein the metal particle obtained by punching and the inorganic particle are mixed in a weight ratio of about 1:

6 to about 3;

1.

10. The thermoplastic resin composition of claim 1, comprising the sparkling particle in an amount of about 0.01 to about 10 parts by weight based on about 100 parts by weight of the thermoplastic resin.

11. A molded product fabricated using the thermoplastic resin composition of claim 1.
