Abstract
Provided herein are a plasticizer composition, a resin composition, and a method of preparing the plasticizer composition. A plasticizer composition capable of enhancing poor physical properties occurring due to structural limitations and enhancing physical properties such as tensile strength, migration resistance, volatile loss, and the like, which are required when used as a plasticizer of a resin composition, and a resin composition including the same may be provided.
Claims15
A resin composition comprising:
- 100 parts by weight of a resin;
- and
- 5 parts by weight of a plasticizer composition comprising:
- a terephthalate-based material;
- and
- an epoxy-based alkyl ester compound represented by Formula 1 below
- wherein a weight ratio of the terephthalate-based material to the epoxy-based alkyl ester compound is 90:10 to 50:50, and the epoxy-based alkyl ester compound is a single compound or a mixture of two or more compounds,
- wherein the terephthalate-based material is a compound selected from the group consisting of diisononyl terephthalate (DINTP), dibutyl terephthalate (DBTP), butyl isononyl terephthalate (BINTP), butyl(2-ethylhexyl)terephthalate (BEHTP), and (2-ethylhexy)isononyl terephthalate (EHINTP):
- wherein, in Formula 1, R1 is a C8-C20 alkyl group containing one or more epoxy groups, and R2 is a C4 or C8 alkyl group, and
- the resin comprises polyvinyl chloride.
