The test piece was left in a hot air circulation oven (80) for 72 hours and then taken out and cooled at room temperature for 4 hours. Then, after removing the PS attached to both sides of the test piece, the weight before and after leaving in the oven was measured and the transfer loss was calculated by the following equation.

% Of transfer loss = {(initial weight of test piece at room temperature-weight of test piece after leaving the oven) / initial weight of test piece at room temperature} x 100

Measurement of volatile loss

After working the prepared specimen for 100 to 168 hours, the weight of the specimen was measured.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

According to one embodiment of the present invention, it is possible to provide a plasticizer composition containing an isophthalate compound. Specifically, the epoxidized oil is applied to the content selected in the range of 1 to 99% by weight, 10 to 99% by weight, 20 to 99% by weight, 30 to 95% by weight or 40 to 90% by weight based on the total weight of the composition Can be. In addition, the content selected from the range of 1 to 50% by weight, 10 to 50% by weight, 10 to 40% by weight, 25 to 50% by weight, 25 to 40% by weight and the like may be applied.

Preferably, the isophthalate compound may be diisononyl isophthalate (DINIP). When the diisononyl isophthalate is applied as the isophthalate compound, it may be more free from environmental problems than the phthalate compound, and may obtain physical properties equivalent to or higher than those of existing products.

According to one embodiment of the invention, the plasticizer composition comprises an isophthalate-based compound, further comprises an epoxidized oil. As described above, in the case of the resin made of the plasticizer composition in which the isophthalate compound and the epoxidized oil are mixed together, the tensile strength, elongation, etc. of the resin is made of the plasticizer composition containing the isophthalate compound alone. It may be excellent in the physical properties of, and may be excellent in tensile and extension residual ratio, heating loss and migration resistance.

Here, the isophthalate compound and the epoxidized oil in the plasticizer composition may be included in a weight ratio of 1:99 to 99: 1.

When the isophthalate compound is diisononyl isophthalate, for example, in a ratio, 99: 1 to 1:99, 90:10 to 10:90, or 90:10 to 20:80 may be applied. Preferably, a ratio of 90:10 to 40:60 may be applied. When the amount of the epoxidized oil is increased, the performance resistance against stress may be excellent, and properties such as tensile strength and elongation may be slightly lowered, but may be included within the required physical properties. Therefore, by controlling the content of the epoxidized oil, it is possible to freely control the required physical properties so that it can be appropriately applied according to the use of the vinyl chloride resin composition.

The epoxidized oil is, for example, epoxidized soybean oil, epoxidized castor oil, epoxidized linseed oil, epoxidized palm oil, epoxidized palm oil, epoxidized stearic acid (epoxidized stearic acid), epoxidized oleic acid, epoxidized tall oil, epoxidized linoleic acid or mixtures thereof may be applied.

Preferably, the epoxidized oil may be epoxidized soybean oil (ESO), epoxidized linseed oil (ELO), or a mixture thereof. However, epoxidized soybean oil may be epoxidized linseed oil due to market conditions or supply and demand problems. The frequency of use may be higher than that.

The plasticizer composition may further include an additive, which may include 1 to 100 parts by weight, preferably 10 to 80 parts by weight, based on 100 parts by weight of the mixed weight of the isophthalate compound and the epoxidized oil. The additive may be mixed with an isophthalate-based compound alone to improve physical properties such as stress characteristics of the resin composition, but a compound having excellent physical properties may be prepared even when only a small amount is included in the mixed plasticizer composition. If the additive is contained in an excessive amount, in controlling the physical properties of the plasticizer composition suitable for the use, problems such as being beyond the control range, undesired properties may be excessively improved, or desired properties may be lowered. Can be generated.

The additive may include one or more compounds selected from the group consisting of phthalate compounds, acetyl citrate compounds, and trimellitate compounds.

The phthalate compound may be, for example, di-2-propylheptyl phthalate, diisodecyl phthalate, diisononyl phthalate, and the acetyl citrate compound may be applied with various acetyl citrate compounds. Acetyl tributyl citrate (ATBC), acetyl triisobutyl citrate (TiBC), acetyl triethylhexyl citrate (ATEHC), acetyl triisononyl citrate (ATiNC) and the like can be applied. In addition, the trimellitate-based compound may also be variously applied in a similar form to the acetyl citrate-based compound, for example, triisobutyl trimellitate (TiBTM), trinormal butyl trimellitate (TnBTM), tri Ethylhexyl trimellitate (TEHTM), triisononyl trimellitate (TINTM), and the like.

As described above, in the case of using a phthalate compound, an acetyl citrate compound, or a trimellitate compound, plasticizing efficiency, tensile strength, elongation, etc. can be improved depending on the mixed material, and stress transfer characteristics, Additional effects, such as improvement in migration resistance, can be obtained.
