US 10,370,517 B2 · Plasticizer composition, resin composition and methods for preparing thereof

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.

Dependent claims

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.
