Problems solved by technology

In addition, in the case where terephthalate (or isophthalate or trimellitate) plasticizers are commercialized by hydrogenation, terephthalic acid from lower alcohols with less mobility Hydrogenation of esters leads to poor mobility, while hydrogenation of terephthalates from higher alcohols with slightly lower elongation only increases cost without improving elongation

preparation example Construction

[0125] The above-mentioned combination can be obtained as a combination of interrelated substances as a product of a production method to be described below, but the possibility of a combination different from the above-mentioned combination is not excluded.

[0126] The plasticizer composition according to one embodiment of the present invention may further contain an aromatic polyester-based substance, which may have come from unreacted substances in the hydrogenation of the raw material. In this case, the content of the aromatic polyester is preferably 0.5% by weight or more relative to the total weight of the plasticizer composition, and preferably, the aromatic polyester does not exceed the weight of the plasticizer composition. 15% by weight of the total weight. When the content of the aromatic polyester is within the above range, the plasticizing efficiency, processability, melting ability, etc. are excellent, and the preparation process can be simplified due to mild hy...

Embodiment 1-1

[0171]A predetermined volume of silica-supported palladium catalyst was charged in a 1.5 L pressure vessel equipped with a stirrer, 25 g of terephthalic acid and 1 L of water as reactants were added and stirred while hydrogen gas was fed using a mass flow meter. While raising the temperature inside the reaction vessel to 200° C. and maintaining the internal hydrogen pressure at 80 bar, the mixture was reacted for one hour. After the reaction was completed, the reaction product in the reaction vessel was recovered and purified using methanol. Thereafter, esterification was performed using 300 mol % of 2-ethylhexanol in the presence of a Ti-based catalyst relative to the hydrogenated product, followed by purification to obtain an ester product in the form of a composition.

Embodiment 1-2

[0173] A predetermined volume of silica-supported palladium catalyst was charged in a 1.5 L pressure vessel equipped with a stirrer, 25 g of terephthalic acid and 1 L of water as reactants were added and stirred while hydrogen gas was fed using a mass flow meter. While raising the temperature inside the reaction vessel to 230° C. and maintaining the internal hydrogen pressure at 80 bar, the mixture was allowed to react for one hour. After the reaction was completed, the reaction product in the reaction vessel was recovered and purified using methanol. Thereafter, esterification was performed using 300 mol % of 2-ethylhexanol in the presence of a Ti-based catalyst relative to the hydrogenated product, followed by purification to obtain an ester product in the form of a composition.

Abstract

The present invention relates to a plasticizer composition for reducing heat loss and for improving thermal stability, and, as mechanical properties, elongation and tensile strength by applying a cyclohexane polyester-based material as a plasticizer and applying, together therewith, a material, which has fewer ester groups than the cyclohexane polyester-based material, as a peroxide.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the priority and rights of Korean Patent Application No. 10-2018-0081209 filed on July 12, 2018, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a plasticizer composition and a resin composition comprising the plasticizer composition, the plasticizer composition comprising a combination of cyclohexane polyester and a specific type of perhydride . Background technique [0004] Typically, plasticizers form esters through the reaction between alcohols and polycarboxylic acids such as phthalic acid or adipic acid. In addition, in consideration of domestic and foreign regulations on phthalate plasticizers that are harmful to the human body, research on plasticizer compositions that can replace phthalate plasticizers such as terephthalate , adipate esters and other polymer plasticizers. [000...
