Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a colorant composition used for coloring and molding a thermoplastic resin, and more particularly to a polyester molded article, and in particular, a thin film molded article such as a polyester film or a sheet or a fiber. The present invention relates to a colorant composition having excellent dispersibility suitable for a colorant. More specifically, the present invention relates to a colorant composition that does not cause deterioration in physical properties of a molded product, and a molded product using the colorant composition.

[0002]

2. Description of the Related Art A colorant composition used for coloring and molding a thermoplastic resin is prepared by mixing a pigment and a dispersant in a powdery dry color, and dispersing the pigment in a liquid dispersant at room temperature. Examples include a liquid color or paste color, and a masterbatch in the form of pellets or flakes obtained by dispersing a pigment at a high concentration in a solid resin at room temperature. In particular, a masterbatch excellent in ease of handling and preservation of the working environment during use is often used.

Hitherto, polyester resins have been used in many fields such as packaging and film applications by taking advantage of their excellent mechanical properties, dimensional stability and chemical resistance. In addition, titanium oxide is used in a large amount as a white pigment for resin coloring because of its excellent whiteness, high concealing property, and high coloring power. In recent years, a colorant composition treated with a polyester resin having such excellent properties and titanium oxide having an excellent concealing property, etc., has been used for a metal plate laminate film, a film for a credit card or a telephone card, a fiber, and other various types. It is widely used for molded articles, and the range of use tends to expand more and more.

In particular, in recent years, in order to satisfy both the demand for thinner and thinner films and the required concealing properties of molded products such as films, the content of titanium oxide in the molded products has been increased (higher). Concentration), and it is necessary to improve the dispersibility of titanium oxide in a molded product. For fiber applications, there is a demand for prevention of yarn breakage during spinning and reduction of clogging frequency of a filter in a spinning machine, that is, high dispersibility of titanium oxide. In order to respond to this demand for molded articles, the colorant composition used when obtaining molded articles has the same requirements, that is, titanium oxide is contained in the colorant composition with good dispersibility and contains a high concentration. Is required.

[0005] On the other hand, titanium oxide used for coloring a polyester resin is generally subjected to various surface treatments in order to improve weather resistance, dispersibility and the like.
This surface treatment is roughly classified into an inorganic treatment (alumina, silica, titania, zirconia, etc.) and an organic treatment (polyol, silicon). By the above treatment, the dispersibility of titanium oxide in the polyester resin is improved, and the weather resistance of the molded article treated with the titanium oxide is also improved.

However, even the titanium oxide treated as described above generally has moisture, and the moisture causes the polyester resin in the colorant composition to be hydrolyzed, resulting in a decrease in molecular weight. . And
The colorant composition treated with such a polyester resin having a reduced molecular weight causes a decrease in the physical properties of a molded article using the colorant composition. In particular, when treated with a high concentration of titanium oxide in the colorant composition, the molecular weight of the polyester resin is significantly reduced, and the use of the colorant composition treated with the polyester resin having a remarkable molecular weight also causes a decrease in the physical properties of the molded product. Become noticeable.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The colorant composition of the present invention suppresses and prevents discoloration due to heat by using titanium oxide treated with Al, improves whiteness, and furthermore, a specific amount of a silane coupling agent or a specific amount of the Al-containing titanium oxide. Dispersibility, hydrophobicity, and concealing properties are improved without causing deterioration of the physical properties of the molded article by treating with a large amount of calcium salt or the like.

The present inventors have found that the metal Nb, Ta, and W remaining as impurities in the sulfuric acid-processed titanium oxide enter crystal defects of the titanium oxide during firing, and the titanium oxide treated with Nb, Ta, and W in the crystal. And N in the crystal
When the titanium oxide treated with b, Ta, and W is used in the field of molding a high melting point resin, for example, a polyester resin (melting point 230 to 260 ° C.), a dark blue colorant composition and a colored molded product can be obtained. The titanium oxide crystal structure after firing is treated with Al instead of Nb, Ta, and W, so that it does not turn blue and black even when used for forming a polyester resin which requires high-temperature processing near 300 ° C. It has been found that a colorant composition and a colored molded product can be obtained.

The amount of Al contained may be 0.02 to 1.0% by weight as long as it is treated with an equivalent amount of Al which can replace metals Nb, Ta and W existing as impurities.
It is preferably at most 0.3% by weight. If it is less than 0.02% by weight, no effect can be obtained in heat discoloration resistance, light discoloration resistance, and weather discoloration resistance. On the other hand, if it exceeds 1.0% by weight, it does not enter the crystal.

The silane coupling agent used in the present invention is used to fix the hydroxyl groups by reacting with the hydroxyl groups on the surface of the titanium oxide and to make the titanium oxide hydrophobic, and to improve the dispersibility. And having a structure represented by the following general formulas (1) to (4), for example, methyltrimethoxysilane,
γ-glycidoxypropyltrimethoxysilane, γ-aminopropyltriethoxysilane, γ-methacryloxypropyltrimethoxysilane, vinyltriethoxysilane, phenylalkoxysilane such as phenyltrialkoxysilane and diphenyldialkoxysilane, and dimethyldimethoxy Examples thereof include silane and dialkyldialkoxysilane such as dimethyldiethoxysilane.

[0033]

Among the organic functional groups of the above general formula, a methyl group and an amino group are preferred, specifically, dialkyldialkoxysilane is preferred, and dimethyldimethoxysilane is particularly preferred.

The titanium oxide contains the silane coupling agent in an amount of 0.05 to 3.0% by weight, preferably 0.05 to 1.0% by weight, more preferably 0.1 to 1.0% by weight.
It is 0.5% by weight, most preferably 0.1-0.3% by weight. If the content exceeds 3.0% by weight, slip occurs during extrusion, and the ejection of the material becomes unstable, so that the colorant composition cannot be manufactured stably. In particular, when a film is produced using the colorant composition, the film thickness becomes non-uniform or the film breaks, making molding impossible. When the content is less than 0.1% by weight, the effect of hydrophobizing titanium oxide is small, and the amount of water absorbed over time after the production of the colorant composition is increased. Promotes hydrolysis of the polyester resin and causes a decrease in molecular weight.

The calcium salt or magnesium salt used in the present invention is used to fix the hydroxyl group by reacting with the hydroxyl group on the surface of titanium oxide and hydrophobize the titanium oxide in the same manner as the silane coupling agent described above. Things. Such calcium salts or magnesium salts include calcium chloride, calcium bromide, calcium iodide, calcium sulfate, magnesium chloride, magnesium bromide, magnesium iodide, magnesium sulfate and the like.

The content is 0.01 to 0.5% by weight in terms of calcium oxide or magnesium oxide. If the content is less than 0.01% by weight, the effect of hydrophobization is insufficient, and if the content is more than 0.5% by weight, the effect of hydrophobization hardly changes.

The content of the calcium salt or magnesium salt as described above is 0.01 to 0.5% by weight. If the content is less than 0.01% by weight, the effect of hydrophobization is insufficient, and if the content is more than 0.5% by weight, the effect of hydrophobization hardly changes.

In the present invention, the treatment with the silane coupling agent and the treatment with a calcium salt, a magnesium salt or the like can be used in combination to fix the hydroxyl groups on the surface of the titanium oxide.

In the present invention, a treatment with a silane coupling agent, a treatment with a calcium salt or the like, or a combined system of a treatment with a silane coupling agent and a treatment with a calcium salt or the like, further comprises an aluminate such as sodium aluminate or the like. Using a silicate, a treatment of alumina, silica or the like can be used in combination. That is, after treating titanium oxide with an aluminate or a silicate or the like, it may be treated with a silane coupling agent, or after treating the titanium oxide with a calcium salt or the like, and then with an aluminate or a silicate. The treatment may be performed, or the titanium oxide may be treated with a calcium salt or the like, then treated with an aluminate or a silicate, and further treated with a silane coupling agent.

Alumina, silica, and the like generally contain water of crystallization or are hydrated. Although it is preferable to reduce the water content as much as possible from the viewpoint of reducing the water content, strong concealing properties are required. In the field, it is preferable to contain as little alumina or silica as possible, preferably 0.3% by weight or less, more preferably 0.2% by weight or less based on titanium oxide.
If it exceeds 0.3% by weight, the water content increases, and the hydrolysis of the polyester resin is easily promoted. Alumina is more preferable in terms of excellent dispersibility.

The titanium oxide used in the present invention is:
The average particle size is preferably 0.01 to 1.0 μm,
More preferably, the thickness is 0.05 to 0.40 μm.
Most preferably, it is 15 to 0.20 μm. Any of rutile type and anatase type may be used, but anatase type is preferred from the viewpoint of whiteness.

When neither treatment with an organic treatment agent such as a silane coupling agent or treatment with an inorganic treatment agent such as alumina was performed, the dispersion of titanium oxide was extremely poor, and the dispersion in the colored resin molded product was extremely poor. Agglomerates are generated and clogging of the screen mesh of the molding machine is caused.

The polyester resin used in the present invention is a conventionally known resin. A polyester obtained by condensation polymerization of an aromatic dicarboxylic acid such as terephthalic acid, isophthalic acid, and naphthalene-2,6-dicarboxylic acid, or an ester thereof and a glycol such as ethylene glycol, diethylene glycol or tetramethylene glycol. is there. Typical examples include polyethylene terephthalate and polybutylene terephthalate. These polyester resins may be a combination of plural kinds of carboxylic acid components and plural kinds of diol components.

The colorant composition of the present invention may be blended with the above-mentioned titanium oxide and polyester resin in a ratio of 2/8 to 8/2, preferably 5/5 to 7/3, and The titanium oxide and the polyester resin may be heated and kneaded using a mixer, a disperser, or a kneader. Further, the colorant composition of the present invention is preferably a pellet-like or flake-like master batch.

The limiting viscosity of the polyester resin in the colorant composition of the present invention indicates the state of deterioration (hydrolysis) of the polyester resin. Containing titanium oxide and polyester resin, heat-kneading the colorant composition using a suitable solvent, dissolve the polyester resin in the colorant composition, separate the titanium oxide, different concentration Using a plurality of polyester resin solutions, the viscosity of each resin solution is determined, and the viscosity / concentration value is plotted against the concentration according to a standard method, and the value is extrapolated to a concentration of 0. The intrinsic viscosity retention rate is a ratio of the intrinsic viscosity of the polyester resin in the colorant composition to the intrinsic viscosity of the polyester resin (blank) used in the colorant composition. As the intrinsic viscosity of the polyester resin in the colorant composition approaches the intrinsic viscosity of the blank, the polyester resin in the colorant composition is not deteriorated.
