Description

plasticizer composition

The present invention exhibits excellent thermal stability and fast gelling speed at the same level as compared to the conventional plasticizer composition containing diethylhexyl cyclohexane dicarboxylate (DEHCH) alone, while exhibiting a significantly lower viscosity, impregnation It relates to an eco-friendly plasticizer composition that can reduce the amount of viscosity reducing agent used when used in layer or wallpaper formulation.

As polymer additives, plasticizers are used to control hardness or ductility, impart stain resistance, modify tensile properties (eg, strength, elongation, or elasticity) and processability.

In the case of phthalate-based plasticizers such as diethylhexyl phthalate (DOP) and diisononyl phthalate (DINP), which have been widely used so far, endocrine disruptors (endocrine) that interfere with or disrupt human hormone action It is suspected of being an environmental hormone that causes disrupters), and there is a movement to regulate its use. Moreover, the use of an eco-friendly plasticizer that is environmentally friendly and harmless to health is essential for the vinyl chloride resin composition applied to the medical field, toys, toys for infants and food, etc., without the generation of these environmental hormones.

As such an eco-friendly plasticizer, a non-phthalate-based plasticizer, dioctyl terephthalate (DOTP), DEHCH (diethylhexyl cyclohexane dicarboxylate), vegetable oil-based eco-friendly plasticizer epoxidized soybean oil (ESO), 1 ,2-Cyclohexane dicarboxylic acid diisononyl ester (1,2-Cyclohexane dicarboxylic acid diisononyl ester; DINCH) is used.

Specifically, Chinese Patent Registration No. 105400106 discloses a vinyl chloride resin composition using DOTP as a plasticizer to provide a highly elastic glove with improved tensile strength. Although DOTP has excellent thermal stability, the gelling rate is slow and the weather resistance is poor. In addition, since the viscosity is high, there is a problem that the amount of the viscosity reducing agent that causes the generation of volatile organic compounds (VOC) is high.

In addition, Korean Patent Application Laid-Open No. 2012-0083560 discloses the use of DEHCH alone or a mixture of DEHCH and DOTP as a plasticizer in the preparation of a vinyl chloride-based resin composition for wallpaper. DEHCH has a low viscosity compared to DOTP when manufacturing plastisol, so it can implement relatively good coating properties, has a fast gelling rate, and has excellent foaming properties. However, there is a problem in that a viscosity reducing agent must still be used together in order to lower the viscosity when used for the impregnation layer or wallpaper formulation. In addition, when DEHCH and DOTP are mixed and used, there is a problem in that the gelling rate of the resin composition is slow and the viscosity is high.

In addition, Japanese Patent No. 4357263 discloses a mixture of DEHCH with an alkylbenzoate-based plasticizer. In this case, although the gelling rate and viscosity are improved, there is a problem in that thermal stability is very poor compared to DOTP and DEHCH.

Accordingly, as an alternative to phthalate-based plasticizers, it is required to develop a non-phthalate-based plasticizer that has physical properties equal to or greater than that of a phthalate-based plasticizer and is friendly, particularly a non-phthalate-based plasticizer that exhibits excellent thermal stability and has a fast gelling rate and low viscosity. have.

plasticizer composition

The plasticizer of the cyclohexane dicarboxylate-based compound represented by DEHCH has a low viscosity compared to DOTP when preparing plastisol, so it can implement relatively excellent coating properties, has a fast gelling rate, and has excellent foaming properties. However, when used for impregnation layer or wallpaper formulation, a viscosity reducing agent must be used together to lower the viscosity. If a viscosity reducing agent is not added, processability is reduced due to high viscosity, and when an excessive viscosity reducing agent is added, a large amount of VOCs are released from the viscosity reducing agent, which not only causes environmental problems, but also causes migration resistance and product quality. this is lowered

In contrast, in the present invention, when preparing a plasticizer composition comprising a cyclohexane dicarboxylate compound, a terephthalate compound exhibiting excellent thermal stability to complement the plasticizer physical properties of the cyclohexane dicarboxylate compound, and a low viscosity By using an alkylbenzoate-based compound that exhibits a significantly faster gelling rate with Remarkably low viscosity. As a result, it is possible to significantly reduce the input amount of the viscosity reducing agent when used for the impregnation layer or wallpaper formulation.

[Formula 1-1]

[Formula 1-2]

[Formula 1-3]

The plasticizer in the wallpaper is easy to seep into the surrounding area by diffusion, and when it seeps into the paper layer in this way, there is a high possibility that the dye in the gypsum board base paper is transferred to the surface of the wallpaper. However, since DEHCH has excellent migration resistance, the amount of diffusion to the outside of the wallpaper is small, and as a result, it is possible to prevent the phenomenon of dye transfer due to less penetration into the paper.

The first plasticizer of the cyclohexane dicarboxylate-based compound may be included in an amount of 20 to 70 parts by weight based on 100 parts by weight of the plasticizer composition, and more specifically, 20 parts by weight or more, or 25 parts by weight or more, or 30 parts by weight or more. and 70 parts by weight or less, or 60 parts by weight or less, or 40 parts by weight or less. When the content of the first plasticizer is too low outside the above range, there is a risk of viscosity increase, and when the content of the first plasticizer is too high, thermal stability may be reduced.

second plasticizer

The second plasticizer of the terephthalate-based compound may be a compound specifically represented by the following Chemical Formula 2:

[Formula 2]

In Formula 2,

R ₃ and R ₄ are each independently a linear or branched chain alkyl group having 4 to 12 carbon atoms, preferably, R ₃ and R ₄ are each independently n-butyl, n-hexyl, n-octyl, 2-ethylhexyl , isononyl, or isodecyl.

If the content of the terephthalate-based compound is too low, thermal stability may be reduced, and if it is too high, the geling rate may be reduced due to an excess of the terephthalate-based compound, the weather resistance may be deteriorated, and the viscosity may increase. More specifically, it may be included in an amount of 20 parts by weight or more, or 30 parts by weight or more, or 40 parts by weight or more, and 70 parts by weight or less, or 60 parts by weight or less.

tertiary plasticizer

Compared with the first and second plasticizers, the third plasticizer of the alkyl benzoate-based compound has a very low viscosity and a very fast gelling rate when preparing plastisol. Therefore, it is possible to further lower the viscosity of the plasticizer composition and further improve processability.

The alkyl benzoate-based compound may be specifically a compound represented by the following Chemical Formula 3:

[Formula 3]

In Formula 3,

R ₅ is a linear or branched chain alkyl having 4 to 20 carbon atoms, preferably a hexyl group, a heptyl group, a 2-ethylhexyl group, an octyl group, a nonyl group, an isononyl group, a 2-propylheptyl group, a decyl group, or It may be an isodecyl group.

Among them, isodecyl benzoate may be appropriately used, and a commercial product thereof (eg, Benzoflex™ 131 (manufactured by EASTMAN), etc.) may be used.

The third plasticizer of the alkyl benzoate-based compound may be included in an amount of 5 to 50 parts by weight based on 100 parts by weight of the plasticizer composition. When the content of the alkyl benzoate-based compound is less than 5 parts by weight, the viscosity of the resin composition may be greatly increased, and coating properties or processability may be deteriorated. Conversely, if the content of the alkyl benzoate-based compound exceeds 50 parts by weight, there may be a problem of deterioration in thermal stability. More specifically, the alkyl benzoate-based compound is included in an amount of 5 parts by weight or more, or 10 parts by weight or more, or 20 parts by weight or more, and 50 parts by weight or less, or 40 parts by weight or less based on 100 parts by weight of the plasticizer composition. can

As described above, the plasticizer composition according to an embodiment of the present invention, together with the first plasticizer of a cyclohexane dicarboxylate-based compound as a nonphthalate-based plasticizer, has a slow gelling rate and high viscosity, but terephthalate exhibiting excellent thermal stability. By including the second plasticizer of the phthalate-based compound and the third plasticizer of the alkyl benzoate-based compound, which has low thermal stability but has a very low viscosity and a very fast gelling rate, compared with the case of using a plasticizer alone of a cyclohexane dicarboxylate-based compound Thus, while exhibiting the same level of excellent thermal stability and gelling speed, the viscosity is significantly low, and as a result, the amount of the viscosity-lowering agent input can be greatly reduced when used for impregnation layer or wallpaper formulation. In addition, this improvement effect may be further enhanced through the combination and content ratio optimization of the first to third plasticizers.

For example, in the plasticizer composition, the total content of the first plasticizer and the third plasticizer may be 120 to 180 parts by weight based on 100 parts by weight of the second plasticizer, and more specifically, 120 parts by weight or more, or 130 parts by weight. or more, and may be 180 parts by weight or less, or 150 parts by weight or less. When included in the above-described mixing ratio, the gelling rate is further improved, the viscosity can be minimized during the preparation of the resin composition by maintaining a low viscosity, and excellent thermal stability can be exhibited.

Furthermore, within the above content range, the first plasticizer and the third plasticizer may be included in a weight ratio of 1:1 to 1:2. When the first and third plasticizers are included in the above weight ratio range, the effect of lowering the viscosity may be further improved while maintaining excellent thermal stability and gelling speed by the first plasticizer. More specifically, the first plasticizer and the third plasticizer may be included in a weight ratio of 1:1 to 1:1.5, or in a weight ratio of 1:1.5 to 1:2.

In another example, in the plasticizer composition, the first plasticizer is di(2-ethylhexyl)cyclohexane-1,4-dicarboxylate, the second plasticizer is dioctylterephthalate, and the third plasticizer is iso decylbenzoate. Among the first to third plasticizer compounds, when the above compounds are used in combination, improved thermal stability and gelling properties may be exhibited along with better plasticizing efficiency.

The plasticizer composition according to an embodiment of the present invention has excellent thermal stability, a fast gelling rate, and low viscosity, and thus exhibits improved processability and workability, and thus can be applied as a plasticizer for various polymer resins. In particular, since it has a lower viscosity than a plasticizer composition containing DEHCH alone, it is possible to reduce the amount of the viscosity reducing agent used in wallpaper formulation, impregnation layer formulation, and the like.

As described above, the plasticizer composition in the resin composition exhibits a low viscosity while exhibiting excellent thermal stability and a fast gelling rate. In particular, since it exhibits a lower viscosity than when DEHCH is used alone, it is possible to reduce the amount of the viscosity reducing agent when used in wallpaper formulation, impregnation layer formulation, and the like. Accordingly, the resin composition may be a resin composition for wallpaper, and a molded article including the same may be a wallpaper.

As a result of the experiment, the vinyl chloride resin composition of Comparative Example 1 using DOTP alone as a plasticizer had excellent thermal stability, but had a slow gelling rate and high viscosity. In addition, the vinyl chloride resin composition of Comparative Example 2 used alone with DEHCH had a faster gelling rate and lower viscosity than Comparative Example 1, but had relatively inferior thermal stability. In addition, the vinyl chloride resin composition of Comparative Example 3 using isodecyl benzoate alone had a very low viscosity and a very fast gelling rate as compared to Comparative Examples 1 and 2, but the thermal stability was greatly reduced to the extent that it was impossible to use.

In addition, the vinyl chloride resin composition of Comparative Example 4 in which DOTP and DEHCH were mixed showed improved thermal stability due to DOPT than in Comparative Example 2 in which DEHCH was used alone, but the viscosity was increased and the gelling rate was slow. In Comparative Example 5 containing DEHCH and isodecyl benzoate, the viscosity and gelling rate were improved compared to Comparative Example 2 using DEHCH alone, but thermal stability was significantly reduced. In Comparative Example 6 containing DOTP and isodecyl benzoate, compared with Comparative Example 2 in which DEHCH was used alone, the viscosity was lowered, but thermal stability was lowered.

In contrast, the vinyl chloride resin compositions of Examples 1 and 2 containing DEHCH, DOTP, and isodecyl benzoate, compared to Comparative Example 2 using DEHCH alone, the gelling rate and thermal stability exhibit the same level of effect, The viscosity was lowered. From these results, it can be seen that when the vinyl chloride resin compositions of Examples 1 and 2 are used for the impregnation layer or wallpaper formulation, the amount of the additive for reducing the viscosity can be reduced.
