Description
本発明は、含塩素樹脂組成物においてハイドロタルサイト型化合物粒子粉末由来の電気絶縁性の低下を抑制でき、且つ、優れた含塩素樹脂の熱安定性を有し、樹脂の着色を抑制できるものである。 In the chlorine-containing resin composition, the present invention can suppress a decrease in electrical insulation derived from hydrotalcite-type compound particle powder, and has excellent thermal stability of the chlorine-containing resin, and can suppress resin coloring. It is.
近年、含塩素樹脂の安定化剤としてＰｂやＳｎから、無毒な金属石鹸類とハイドロタルサイト型化合物の組合せに変わりつつあり、含塩素樹脂を用いた材料は、電線被覆、フィルム、建材やパイプなど様々な用途で利用されている。 In recent years, as a stabilizer for chlorine-containing resins, Pb and Sn are changing to a combination of non-toxic metal soaps and hydrotalcite-type compounds, and materials using chlorine-containing resins include wire coatings, films, building materials and pipes. It is used for various purposes.
ハイドロタルサイトは一般的に、Ｍｇ６Ａｌ２（ＯＨ）１６ＣＯ３・４Ｈ２Ｏで示される層状の化合物で、Ｍｇ−Ａｌからなる層の層間にＣＯ３、Ｈ２Ｏ、ＯＨ−が挿入されている。構造中のＭｇ２＋の一部もしくは全部をＮｉ２＋、Ｚｎ２＋、Ｓｒ２＋やＣａ２＋等の２価カチオンと置き換えることができ、同様にＡｌ３＋の一部もしくは全部をＦｅ３＋やＣｒ３＋等の３価カチオンと置き換えることができる。さらに、ＣＯ３ ２−もＳＯ４ ２−やＣｌ−等のアニオンと交換することができる。また、一般的に２価と３価のカチオンのモル比を変えても構造を保持し、モル比が２〜４の範囲で層状構造をとることができる。これら構成元素の組成や２価と３価のカチオンの比率を変えた層状の化合物を一般的にハイドロタルサイト型化合物と呼ぶ。 Hydrotalcite is generally a layered compound represented by Mg 6 Al 2 (OH) 16 CO 3 .4H 2 O, and CO 3 , H 2 O, and OH − are inserted between layers of Mg—Al. Has been. Part or all of Mg 2+ in the structure can be replaced with divalent cations such as Ni 2+ , Zn 2+ , Sr 2+ and Ca 2+ , and part or all of Al 3+ can be replaced with Fe 3+ , Cr 3+, etc. It can be replaced with a trivalent cation. Furthermore, CO 3 2− can also be exchanged with anions such as SO 4 2− and Cl − . In general, the structure can be maintained even when the molar ratio of divalent and trivalent cations is changed, and a layered structure can be formed in a molar ratio of 2 to 4. Layered compounds in which the composition of these constituent elements and the ratio of divalent and trivalent cations are changed are generally called hydrotalcite compounds.
特に電線被覆用途の安定剤では急激にハイドロタルサイト型化合物を含むものに変わりつつある。しかし、電線被覆用途の安定剤にハイドロタルサイト型化合物を用いると電気抵抗が低下する傾向があり、低電圧電線では、なんとか使用できるレベルであるが、高電圧電線では漏電しやすくなるので使用することが出来ず、依然として電気絶縁性の高いＰｂ系の安定剤が使用されている。 In particular, stabilizers for wire coating applications are rapidly changing to those containing hydrotalcite type compounds. However, if hydrotalcite-type compounds are used as stabilizers for wire coating applications, the electrical resistance tends to decrease, and it can be used for low-voltage wires. Pb-based stabilizers with high electrical insulation are still used.
しかし、環境への配慮から高電圧電線でも脱Ｐｂが求められており、高い電気絶縁性を保持できるハイドロタルサイト型化合物が渇望されている。 However, removal of Pb is required even for high-voltage electric wires in consideration of the environment, and a hydrotalcite-type compound that can maintain high electrical insulation is craved.
一般的に水溶液等では溶解したイオンを多く含むほど導電性は高くなり、樹脂中でも同様に導電性のイオンが多いほど樹脂の導電性が高くなる。言い換えれば導電性イオンが多いほど樹脂の電気絶縁性は低下する。 Generally, in an aqueous solution or the like, the more the dissolved ions are contained, the higher the conductivity, and the more conductive ions in the resin, the higher the conductivity of the resin. In other words, the more conductive ions, the lower the electrical insulation of the resin.
ハイドロタルサイト型化合物粒子はその構造中及び表面付近に硫酸イオンやナトリウムイオンの様な微量の不純物イオンを含んでおり、電気絶縁性を低下させる原因となっていると考えられる。また、これらのイオンは樹脂の着色や熱安定性を悪化させる原因ともなっている。 Hydrotalcite-type compound particles contain a trace amount of impurity ions such as sulfate ions and sodium ions in the structure and in the vicinity of the surface, and are considered to be a cause of lowering electrical insulation. These ions are also a cause of deterioration of resin coloring and thermal stability.
これまで塩素含有樹脂の安定剤としてハイドロタルサイト型化合物を用いることが知られており（特許文献１〜３）、ハイドロタルサイト型化合物粒子が含有するナトリウム量が少ないと電気抵抗が向上する傾向があることも知られている（特許文献２、３）。 It has been known so far to use hydrotalcite type compounds as stabilizers for chlorine-containing resins (Patent Documents 1 to 3), and the electrical resistance tends to improve when the amount of sodium contained in the hydrotalcite type compound particles is small. It is also known that there are (Patent Documents 2 and 3).
前記特許文献１乃至３に記載されたハイドロタルサイト型化合物では、樹脂の電気絶縁性が十分とは言い難く、含塩素樹脂組成物の安定剤として優れた機能を有するとは言い難いものであった。 In the hydrotalcite-type compounds described in Patent Documents 1 to 3, it is difficult to say that the electrical insulation of the resin is sufficient, and it is difficult to say that the resin has an excellent function as a stabilizer for the chlorine-containing resin composition. It was.
そこで、本発明は、溶出する導電性イオンが少ないハイドロタルサイト型化合物を提供し、該ハイドロタルサイト型化合物を含む高い電気絶縁性を持った樹脂を提供することを技術的課題とする。 Therefore, it is a technical object of the present invention to provide a hydrotalcite-type compound with a small amount of conductive ions to be eluted and to provide a resin having a high electrical insulation property containing the hydrotalcite-type compound.

本発明に係る溶出する導電性イオンが少ないハイドロタルサイト型化合物粒子粉末において、ハイドロタルサイト型化合物はＭｇ，Ａｌ，Ｚｎなどから構成されており、俗にＭｇ−Ａｌ系やＭｇ−Ｚｎ−Ａｌ系と表記されるものである。 In the hydrotalcite-type compound particle powder with a small amount of eluting conductive ions according to the present invention, the hydrotalcite-type compound is composed of Mg, Al, Zn, etc., commonly known as Mg-Al type or Mg-Zn-Al.

If the amount of these soluble anions is large, high electrical insulation cannot be obtained. In particular, bivalent sulfate ions have a greater adverse effect on electrical insulation than monovalent ions. The soluble anion is preferably 60 ppm or less, more preferably 50 ppm or less. The lower limit is about 5 ppm.
本発明に係るハイドロタルサイト型化合物粒子粉末が含むナトリウムは７００ｐｐｍ以下が好ましい。含有するナトリウムが少なければ溶解するナトリウムが少なくなる可能性が高くなる。ナトリウムイオンは可溶性アニオンよりも影響が少ないものの、ナトリウムが少ない方がより高い電気絶縁性が得られる。好ましくはナトリウムが６００ｐｐｍ以下であり、更により好ましくは５５０ｐｐｍ以下である。下限値は２０ｐｐｍ程度である。 The sodium contained in the hydrotalcite-type compound particle powder according to the present invention is preferably 700 ppm or less. If less sodium is contained, there is a higher possibility that less sodium will be dissolved. Although sodium ions have less influence than soluble anions, higher electrical insulation is obtained with less sodium. Preferably sodium is 600 ppm or less, and even more preferably 550 ppm or less. The lower limit is about 20 ppm.
本発明に係るハイドロタルサイト型化合物粒子粉末の比表面積は５〜１５０ｍ２／ｇである。５ｍ２／ｇ未満のハイドロタルサイト型化合物粒子は工業的に得られにくい。１５０ｍ２／ｇを超えても工業的に得られにくい。好ましくは７〜１００ｍ２／ｇ、より好ましくは８〜５０ｍ２／ｇである。 The specific surface area of the hydrotalcite-type compound particle powder according to the present invention is 5 to 150 m 2 / g. Hydrotalcite-type compound particles of less than 5 m 2 / g are difficult to obtain industrially. Even if it exceeds 150 m 2 / g, it is difficult to obtain industrially.

次に、本発明に係るハイドロタルサイト型化合物粒子粉末の製造法について述べる。 Next, the manufacturing method of the hydrotalcite type compound particle powder concerning this invention is described.
本発明に係るハイドロタルサイト型化合物粒子粉末は、ハイドロタルサイト型粒子を生成及び熟成させた後のスラリー又は疎水化表面処理などの処理を行った後のスラリーを、ｐＨ９．５〜１２に調整した後、洗浄し、乾燥して得られるものであり。 The hydrotalcite type compound particle powder according to the present invention adjusts the slurry after the hydrotalcite type particles are generated and aged, or the slurry after the treatment such as the hydrophobized surface treatment to pH 9.5 to 12 After washing and drying.
本発明におけるハイドロタルサイト型化合物粒子粉末は、アニオンを含有したアルカリ性水溶液とマグネシウム塩水溶液とアルミニウム塩水溶液とを混合し、ｐＨ値が１０〜１４の範囲の混合溶液とした後、該混合溶液を８０〜１０５℃の温度範囲で熟成してＭｇ−Ａｌ系ハイドロタルサイト型粒子の芯粒子を生成させ、次いで、該芯粒子を含む水性懸濁液に、該芯粒子の生成時に添加した前記マグネシウムと前記アルミニウムとの合計モル数に対して、合計モル数が０．３５以下となる割合でマグネシウム及びアルミニウムを含有するマグネシウム塩水溶液とアルミニウム塩水溶液とを添加した後、ｐＨ値が１０〜１４の範囲、温度が６０〜１０５℃の範囲で熟成してＭｇ−Ａｌ系ハイドロタルサイト型粒子粉末を得るような常圧での芯粒子に対する成長反応（特開２００２−２９３５３５号公報）や、オートクレーブを用いて１０５〜３５０℃にて生成されたものを用いることが望ましい。これらは、例えば、Ｍｇ，Ａｌ，Ｚｎについては硫酸塩金属、硝酸塩金属、塩化物塩金属、金属酸化物などの原料と、苛性ソーダや水酸化カリウムなどのアルカリ、炭酸ソーダや塩基性炭酸マグネシウム、炭酸カリウムなどのアニオン源原料から作製すればよい。 In the hydrotalcite-type compound particle powder in the present invention, an alkaline aqueous solution containing an anion, a magnesium salt aqueous solution, and an aluminum salt aqueous solution are mixed to obtain a mixed solution having a pH value in the range of 10 to 14, and then the mixed solution is used. The magnesium added at the time of production of the core particles to the aqueous suspension containing the core particles by producing the core particles of Mg-Al hydrotalcite particles by aging in the temperature range of 80 to 105 ° C. After adding magnesium salt aqueous solution and aluminum salt aqueous solution containing magnesium and aluminum in a ratio that the total number of moles is 0.35 or less with respect to the total number of moles of aluminum and aluminum, the pH value is 10-14 Core particles at normal pressure such that Mg-Al hydrotalcite-type particle powder is obtained by aging in the range of 60 to 105 ° C. Growth and reaction (JP-2002-293535) for, it is desirable to use a generated at one hundred and five to three hundred and fifty ° C. using an autoclave. For example, for Mg, Al, and Zn, raw materials such as sulfate metal, nitrate metal, chloride salt metal, and metal oxide, alkali such as caustic soda and potassium hydroxide, sodium carbonate, basic magnesium carbonate, carbonate What is necessary is just to produce from anion source materials, such as potassium.
可溶性アニオン（可溶性硫酸イオン、可溶性硝酸イオン及び可溶性塩化物イオン）の少ないハイドロタルサイト型化合物粒子を作製するには、目標とするハイドロタルサイト型化合物粒子を生成及び熟成させた後のスラリー、又は疎水化表面処理などの処理を行った後のスラリーを、ｐＨ９．５〜１２に調節することが好ましく、より好ましいｐＨは９．８〜１１．５である。前記ｐＨの範囲に調整することで硫酸イオン等のアニオンが水洗で低下しやすくなる。ナトリウムは水洗で比較的容易に落ちやすいが、可溶性硫酸イオン、可溶性硝酸イオン及び可溶性塩化物イオンのような可溶性アニオンは単に水洗では低減することが困難である。そこで、水洗時に、まず薄いアルカリ水溶液で洗浄して硫酸イオン等のアニオンを低減させてから、さらに水で水洗することで、より硫酸イオン等のアニオンが低下しやすくなる。前記ハイドロタルサイト型粒子粉末を含有するスラリーのｐＨ調節及び水洗前の洗浄で用いる薄いアルカリ水溶液には、水酸化ナトリウム、炭酸ナトリウムなどのアルカリ水溶液を用いればよい。 In order to produce hydrotalcite-type compound particles with less soluble anions (soluble sulfate ions, soluble nitrate ions and soluble chloride ions), a slurry after the target hydrotalcite-type compound particles are generated and aged, or The slurry after the treatment such as the hydrophobized surface treatment is preferably adjusted to pH 9.5 to 12, and more preferably 9.8 to 11.5. By adjusting to the pH range, anions such as sulfate ions are likely to be lowered by washing with water. Sodium tends to fall relatively easily with water washing, but soluble anions such as soluble sulfate ions, soluble nitrate ions and soluble chloride ions are difficult to reduce simply by washing. Therefore, at the time of washing with water, washing with a thin alkaline aqueous solution first to reduce anions such as sulfate ions, and then washing with water further reduces the anions such as sulfate ions. An alkaline aqueous solution such as sodium hydroxide or sodium carbonate may be used as the thin alkaline aqueous solution used for pH adjustment of the slurry containing the hydrotalcite-type particle powder and washing before washing with water.
さらに、薄いアルカリ水溶液及び／又は水洗に用いる薄いアルカリ水溶液及び／又は水は冷水よりも３０〜９０℃の温水を用いることが好ましい。前記温度範囲の薄いアルカリ水溶液及び／又は水を用いるとイオンの拡散速度が向上し、さらに水の粘度が低下して水洗効果が高まる。より好ましくは４０〜７０℃である。 Furthermore, it is preferable to use 30-90 degreeC hot water rather than cold water for the thin alkaline aqueous solution and / or the thin alkaline aqueous solution and / or water used for water washing. When an alkaline aqueous solution and / or water having a thin temperature range is used, the diffusion rate of ions is improved, and the viscosity of water is further lowered to increase the washing effect. More preferably, it is 40-70 degreeC.
上記のようにして得られたハイドロタルサイト型化合物粒子粉末は、基本的には１０５〜１５０℃にて乾燥を行うことが好ましい。１０５℃未満の乾燥温度では得られるハイドロタルサイト型化合物粒子粉末の水分が多いので樹脂中で発泡が起きやすく、また乾燥させるために長時間必要となり経済的ではない。１５０℃を超える場合は、軟質〜半硬質含塩素樹脂組成物の安定剤用途として樹脂に対する劣化抑制の働きが低下する傾向にある。軟質〜半硬質含塩素樹脂組成物の安定剤用途では、乾燥温度は１０５〜１３０℃がより好ましい。乾燥時間は乾燥量や乾燥方法によって必要な時間行えばよい。好ましくは３〜２４ｈである。 Basically, the hydrotalcite-type compound particle powder obtained as described above is preferably dried at 105 to 150 ° C. At a drying temperature of less than 105 ° C., the resulting hydrotalcite-type compound particle powder has a large amount of water, so that foaming is likely to occur in the resin. When it exceeds 150 degreeC, it exists in the tendency for the function of the deterioration suppression with respect to resin to fall as a stabilizer use of a soft-semi-rigid chlorine containing resin composition. In the use of a soft to semi-rigid chlorine-containing resin composition as a stabilizer, the drying temperature is more preferably 105 to 130 ° C. The drying time may be as long as necessary depending on the amount of drying and the drying method. Preferably it is 3-24h.
次に、本発明に係る含塩素樹脂安定剤及び含塩素樹脂組成物について述べる。 Next, the chlorine-containing resin stabilizer and chlorine-containing resin composition according to the present invention will be described.

本発明に係る含塩素樹脂組成物は、樹脂１００重量部に対して、前記ハイドロタルサイト型化合物粒子粉末を０．０１〜１０重量部含有することが好ましい。ハイドロタルサイト型化合物粒子粉末の含有量が０．０１重量部未満の場合には、安定剤としての効果が低い。１０重量部を超える場合には、効果が飽和するため必要以上に添加する意味がない。また、ハイドロタルサイト型粒子粉末を必要以上に多量に添加すると、発泡が起こりやすく、外観不良や初期着色等の悪影響を及ぼす場合がある。 The chlorine-containing resin composition according to the present invention preferably contains 0.01 to 10 parts by weight of the hydrotalcite-type compound particle powder with respect to 100 parts by weight of the resin. When the content of the hydrotalcite-type compound particle powder is less than 0.01 parts by weight, the effect as a stabilizer is low. When the amount exceeds 10 parts by weight, the effect is saturated, so there is no point in adding more than necessary. Moreover, when hydrotalcite-type particle powder is added in a larger amount than necessary, foaming is likely to occur, which may have adverse effects such as poor appearance and initial coloration.
