## Abstract

The present invention relates to a plasticizer composition, a resin composition and methods for preparing thereof, and, by improving poor physical properties having been caused by structural limitation, provides a plasticizer capable of improving physical properties such as plasticizing efficiency, a migration property, tensile strength, an elongation rate, stress migration and light resistance required for sheet formularization when used as a plasticizer of a resin composition, and a resin composition comprising the same.

## Claims

### Claim 1

A plasticizer composition comprising:
one kind of terephthalate-based material; and
epoxidized oil; and
an additive, which is a trimellitate-based material,
wherein weight ratio of the terephthalate-based material and the epoxidized oil is from 90:10 to 1:99,
wherein the epoxidized oil is included in 10% by weight or greater with respect to the total amount of the plasticizer composition, and
wherein the trimellitate-based material comprises one or more selected from the group consisting of tri(2-ethylhexyl) trimellitate and triisononyl trimellitate.

### Claim 2 (depends on 1)

The plasticizer composition of claim 1, wherein the weight ratio of the terephthalate-based material and the epoxidized oil is from 90:10 to 50:50.

### Claim 3 (depends on 1)

The plasticizer composition of claim 1, wherein the terephthalate-based material is any one selected from the group consisting of di(2-ethylhexyl) terephthalate (DEHTP or DOTP), diisononyl terephthalate (DINTP), dibutyl terephthalate (DBTP), butylisononyl terephthalate (BINTP), butyl(2-ethylhexyl) terephthalate (BEHTP or BOTP) and (2-ethylhexyl)isononyl terephthalate (EHINTP or OINTP).

### Claim 4 (depends on 3)

The plasticizer composition of claim 3, wherein the terephthalate-based material is di(2-ethylhexyl) terephthalate or diisononyl terephthalate.

### Claim 5 (depends on 1)

The plasticizer composition of claim 1, wherein the epoxidized oil comprises at least one selected from the group consisting of epoxidized soybean oil, epoxidized castor oil, epoxidized linseed oil, epoxidized palm oil, epoxidized stearate, epoxidized oleate, epoxidized tall oil and epoxidized linoleate.

### Claim 6 (depends on 1)

The plasticizer composition of claim 1, wherein the additive is comprised 1 part by weight to 100 parts by weight based on 100 parts by weight of the plasticizer composition.

### Claim 7

A method for preparing a plasticizer composition comprising:
providing one kind of terephthalate-based material and epoxidized oil;
blending the terephthalate-based material and the epoxidized oil at weight ratio of from 90:10 to 1:99 to prepare a plasticizer composition; and
mixing a trimellitate-based material with the plasticizer composition, and
wherein the epoxidized oil is included in 10% by weight or greater with respect to the total amount of the plasticizer composition,
wherein the trimellitate-based material comprises one or more selected from the group consisting of tri(2-ethylhexyl) trimellitate and triisononyl trimellitate.

### Claim 8 (depends on 7)

The method for preparing the plasticizer composition of claim 7, wherein the terephthalate-based material is prepared by conducting direct esterification of an alcohol and terephthalic acid, wherein the alcohol is selected from the group consisting of 2-ethylhexyl alcohol, isononyl alcohol, butyl alcohol and isobutyl alcohol.

### Claim 9 (depends on 7)

The method for preparing the plasticizer composition of claim 7, wherein the trimellitate-based material is mixed with the plasticizer composition in an amount of 1 part by weight to 100 parts by weight based on 100 parts by weight of the plasticizer composition.

### Claim 10 (depends on 1)

A resin composition comprising:
100 parts by weight of a resin; and
5 parts by weight to 150 parts by weight of the plasticizer composition of claim 1.

### Claim 11 (depends on 10)

The resin composition of claim 10, wherein the resin is at least one selected from the group consisting of ethylene vinyl acetate, polyethylene, polyketone, polypropylene, polyvinyl chloride, polystyrene, polyurethane and thermoplastic elastomers.

### Claim 12 (depends on 10)

The resin composition of claim 10, wherein the resin composition is a material for at least one selected from the group consisting of wires, flooring materials, automotive interior materials, films, sheets, wallpapers and tubes.
