【発明の属する技術分野】
本発明は、結晶性合成樹脂組成物に関し、詳しくは結晶性合成樹脂に(a)アルカリ金属カルボン酸塩、(b)環状有機リン酸エステル塩基性アルミニウム塩、並びに(c)アルカリ金属、アルカリ土類金属、アルミニウム及び亜鉛から選ばれる金属の水酸化物又は酸化物を配合してなる、透明性及び着色性の改善された結晶性合成樹脂組成物に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
ポリエチレン、ポリプロピレン、ポリブテン−1、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリフェニレンスルフィド、ポリアミド等の結晶性合成樹脂は、加熱溶融成型後の結晶化速度が遅いため成型サイクル性が低く、また、加熱成型後の結晶化の進行によって収縮するという欠点があった。また、これらの結晶性合成樹脂は、大きな結晶が生成するために、強度が不充分であったり、透明性が劣るという欠点もあった。
【0003】
これらの欠点は、すべて、合成樹脂の結晶性に由来するものであり、合成樹脂の結晶化温度を高め、微細な結晶を急速に生成させることができれば解消されることが知られている。
【0004】
上記欠点を解消する目的のために、結晶核剤あるいは結晶化促進剤を添加することが知られており、従来から、4−第三ブチル安息香酸アルミニウム塩、アジピン酸ナトリウム等のカルボン酸金属塩、ナトリウムビス(4−第三ブチルフェニル)ホスフェート、ナトリウム−2,2’−メチレンビス(4,6−ジ第三ブチルフェニル)ホスフェート等の酸性リン酸エステル金属塩、ジベンジイリデンソルビトール、ビス(4−メチルベンジリデン)ソルビトール等の多価アルコール誘導体等の化合物が用いられていた。
【0005】
これらの化合物の中でも、特許文献1及び特許文献2等に記載されているアルキリデンビスフェノール類の環状リン酸エステルの金属塩は、その効果が大きく、広く用いられている。
【0006】
また、これらの化合物と他の金属化合物とを併用することによってその効果の改善を図ろうとする試みも行われている。例えば、特許文献3には、芳香族リン酸アルカリ金属塩系造核剤とステアリン酸カルシウム等のアルカリ土類金属カルボン酸塩とを併用した場合の剛性の低下を防止するために、アルカリ土類金属カルボン酸に代えて、ハイドロタルサイト類又はアルカリ金属カルボン酸塩を用いる方法が提案されている。また、特許文献4及び5には、環状有機リン酸エステル金属塩と脂肪族カルボン酸の周期律表第II族金属塩とを併用する方法が提案され、特許文献6及び7には、酸性有機リン酸エステル化合物と脂肪族カルボン酸金属塩とを併用する方法が提案されている。また、特許文献8には、環状有機リン酸エステル金属塩を用いた場合に、後処理として放射線照射が施された後の熱水浸漬におけるpHの低下を防止するため、アルカリ金属、アルカリ土類金属又はアルミニウム族金属の水酸化物を併用することが提案されている。
【0007】
しかしながら、これらの化合物の組み合わせによる改善効果は、実用上は未だ満足できるものではなく、特に結晶性合成樹脂の透明性の改善という観点からは、更なる改良が求められていた。
【0008】
さらに、特許文献9〜11には、高剛性プロピレン系樹脂の加工性及び耐熱剛性を改良するために、芳香族リン酸ジエステルの塩基性アルミニウム塩を用いることが提案されているが、このような化合物を用いた場合には透明性の改良効果はほとんど認められず、このような塩基性の化合物は、合成樹脂の透明性改善には効果が乏しいものと考えられていた。さらに、特許文献12では、芳香族リン酸ジエステルの塩基性アルミニウム塩及びアルカリ金属カルボン酸塩を併用することで、結晶性合成樹脂の透明性を改善することが提案されているが、着色性等の加工安定性に関しては未だ満足のいくものではなかった。
【0009】
従って、本発明の目的は、透明性を低下させることなく、着色性にも優れ、且つ後処理を施す用途に好適な、結晶性合成樹脂組成物を提供することにある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a crystalline synthetic resin composition, and more particularly, to (a) an alkali metal carboxylate, (b) a basic aluminum salt of a cyclic organic phosphate, and (c) an alkali metal or alkaline earth metal. The present invention relates to a crystalline synthetic resin composition having improved transparency and colorability, comprising a hydroxide or oxide of a metal selected from the class of metals, aluminum and zinc.
[0002]
Problems to be solved by the prior art and the invention
Crystalline synthetic resins such as polyethylene, polypropylene, polybutene-1, polyethylene terephthalate, polybutylene terephthalate, polyphenylene sulfide, and polyamide have a low molding cycle property due to a low crystallization rate after heat-melt molding, and also have a low There is a drawback that shrinkage occurs as crystallization proceeds. In addition, these crystalline synthetic resins also have drawbacks of insufficient strength and poor transparency due to generation of large crystals.
[0003]
All of these drawbacks are derived from the crystallinity of the synthetic resin, and it is known that if the crystallization temperature of the synthetic resin can be increased and fine crystals can be rapidly generated, these problems can be solved.
[0004]
It is known to add a nucleating agent or a crystallization accelerator for the purpose of solving the above-mentioned drawbacks. Conventionally, carboxylic acid metal salts such as aluminum 4-tert-butylbenzoate and sodium adipate have been known. Acid phosphate metal salts such as sodium bis (4-tert-butylphenyl) phosphate, sodium-2,2'-methylenebis (4,6-di-tert-butylphenyl) phosphate, dibenzylidenesorbitol, bis ( Compounds such as polyhydric alcohol derivatives such as 4-methylbenzylidene) sorbitol have been used.
[0005]
Among these compounds, the metal salts of cyclic phosphoric acid esters of alkylidene bisphenols described in Patent Literature 1 and Patent Literature 2 are widely used because of their great effects.
[0006]
Attempts have also been made to improve the effects by using these compounds in combination with other metal compounds. For example, Patent Literature 3 discloses an alkaline earth metal in order to prevent a decrease in rigidity when an aromatic alkali metal phosphate nucleating agent and an alkaline earth metal carboxylate such as calcium stearate are used in combination. A method using hydrotalcites or alkali metal carboxylate instead of carboxylic acid has been proposed. Patent Documents 4 and 5 propose a method of using a metal salt of a cyclic organic phosphate and a metal salt of Group II of the periodic table of an aliphatic carboxylic acid in combination. Patent Documents 6 and 7 disclose acidic organic compounds. A method in which a phosphate ester compound and an aliphatic carboxylic acid metal salt are used in combination has been proposed. Patent Document 8 discloses that when a metal salt of a cyclic organic phosphate is used, an alkali metal or an alkaline earth metal is used in order to prevent a decrease in pH in hot water immersion after irradiation with radiation as a post-treatment. It has been proposed to use a metal or aluminum group metal hydroxide in combination.
[0007]
However, the improvement effect of the combination of these compounds is not yet satisfactory in practical use, and further improvement has been demanded, particularly from the viewpoint of improving the transparency of the crystalline synthetic resin.
[0008]
Further, Patent Documents 9 to 11 propose use of a basic aluminum salt of an aromatic phosphoric diester in order to improve the processability and heat resistance of a high-rigidity propylene-based resin. When a compound was used, the effect of improving the transparency was scarcely recognized, and such a basic compound was considered to be poor in the effect of improving the transparency of the synthetic resin. Furthermore, Patent Document 12 proposes to improve the transparency of a crystalline synthetic resin by using a combination of a basic aluminum salt of an aromatic phosphate diester and an alkali metal carboxylate. The processing stability was not yet satisfactory.
[0009]
Therefore, an object of the present invention is to provide a crystalline synthetic resin composition which is excellent in coloring property without lowering transparency and suitable for use in performing post-treatment.

The following <formulation> was mixed with a Henschel mixer for 5 minutes, extruded at 250 ° C., and injection-molded a test piece having a thickness of 1 mm at 230 ° C. The haze (haze value) and yellowness (YI (initial)) of this test piece were measured. YI was also measured after being left in an atmosphere at 120 ° C. for 3 weeks. In addition, the following <eluate test> was performed on the pellets prepared from the above blends. The results are shown in [Table 1] and [Table 2].

<Eluent test>
Place 20 g of the pellet in a hard glass container having a volume of about 300 ml, add exactly 200 ml of water, seal with a suitable stopper, heat at 121 ° C. for 1 hour using a high-pressure steam sterilizer, and leave until reaching room temperature. Thus, a test solution was obtained. Separately, a blank control solution was prepared in the same manner using only water without a pellet. The test solution was subjected to an ultraviolet absorption spectrum substance detection test by an absorbance measurement method using the blank test solution as a control. [Table 1] and [Table 2] show the test results in terms of absorbance. The criteria for the test conformity are that the absorbance at a wavelength of 220 nm or more and less than 241 nm is 0.08 or less, and the absorbance at a wavelength of 241 nm or more and 350 nm or less is 0.05 or less.

As is clear from [Table 1] and [Table 2], when only the component (a) or the component (b) or the component (a) and the component (b) are added to the crystalline synthetic resin, the transparency is improved. While maintaining it, excellent colorability cannot be achieved, and it is not compatible with the dissolution test after sterilization (Comparative Examples 1-2 to 1-4). Further, even if hydrotalcite is further added in addition to the components (a) and (b), the coloring property is not sufficient, and the dissolution test after sterilization is not suitable (Comparative Example 1-1). . On the other hand, when the components (a) to (c) are added to the crystalline synthetic resin, the transparency is excellent, the colorability is excellent, and the dissolution test after sterilization is suitable (Example 1). -1 to 1-8).
