Abstract
Description
本発明は、触媒能や抗菌性等の機能を有する高分子化合物成型品を得る方法に関する。更に詳しくは、本発明は、触媒能や抗菌性等の機能性を付与する粒子を高分子化合物成型品の表面へ担持させて、機能性を有する高分子化合物成型品を得る方法に関する。 The present invention relates to a method for obtaining a polymer compound molded article having functions such as catalytic ability and antibacterial properties. More specifically, the present invention relates to a method for obtaining a polymer compound molded product having functionality by supporting particles imparting functionality such as catalytic ability and antibacterial property on the surface of the polymer compound molded product.
従来、高分子化合物成型品（繊維、フィルム等）の付加価値を高めるために、高分子化合物成型品に各種機能を有する機能性付与粒子を担持させることが広く行われており、例えば、溶液状のバインダーに機能性付与粒子を分散させたバインダー溶液中に高分子化合物成型品を浸漬させる「ディッピング法」や、同じく溶液状のバインダーに機能性付与粒子を分散させたバインダー溶液を高分子化合物成型品表面にスプレーして固着する「スプレーコート法」などが知られている。 Conventionally, in order to increase the added value of a polymer compound molded product (fiber, film, etc.), it has been widely carried out that functional polymer particles having various functions are supported on the polymer compound molded product. "Dipping method" in which a polymer compound molded product is immersed in a binder solution in which functional particles are dispersed in a binder, or a binder solution in which functional particles are dispersed in a solution-like binder. The “spray coating method” is known in which the product surface is sprayed and fixed.
これらの方法では、バインダー溶液の化学的組成や、浸漬、スプレー等の処理条件を工夫することにより、固着粒子の脱落耐久性や加工性を高める試みが多くなされているが、バインダー溶液にはバインダー成分のほかにも分散剤成分など多くの成分が必要とされるため、必然的にコストが高くなるという問題があった。また、上記バインダー溶液を高分子化合物成型品に塗布した後、バインダー溶液中の揮発成分を除去するために多くの熱エネルギーと時間とを要するという問題もある。 In these methods, many attempts have been made to increase the durability and processability of the fixed particles by devising the chemical composition of the binder solution and the processing conditions such as dipping and spraying. In addition to the components, many components such as a dispersant component are required, which inevitably increases the cost. In addition, after the binder solution is applied to a polymer compound molded article, there is also a problem that much heat energy and time are required to remove volatile components in the binder solution.
更に、機能性付与粒子の表面のみならず、高分子化合物成型品の表面をもバインダー溶液が被覆してしまうため、表面に吸着サイトなどの微小な機能性高次構造を有する材料においては、その機能が制限されてしまうという問題もあった。 Furthermore, since the binder solution covers not only the surface of the functionalized particles but also the surface of the polymer compound molded product, in the material having a fine functional higher order structure such as an adsorption site on the surface, There was also a problem that the function was limited.
これらの問題を解決すべく、バインダーを使用しない機能性付与粒子の不織布への担持方法についても検討がなされており、熱可塑性高分子繊維から成る不織布に機能性付与粒子を乾式法で担持させた後、熱処理により熱可塑性高分子不織布の少なくとも表面を軟化させて、該繊維表面に機能性付与粒子を固着させる方法（例えば、特許文献１等参照。）が提案されている。 In order to solve these problems, a method for supporting functionally imparted particles without using a binder on a nonwoven fabric has also been studied, and functionally imparted particles are supported by a dry method on a nonwoven fabric composed of thermoplastic polymer fibers. Thereafter, a method has been proposed in which at least the surface of the thermoplastic polymer nonwoven fabric is softened by heat treatment to fix the functional particles to the fiber surface (for example, see Patent Document 1).
この方法を用いることにより、少ない操作工程で生産が可能な上、担持した機能性付与粒子が水洗処理などによって脱落しないなどの利点が得られる。しかし、乾式法によって機能性付与粒子を担持する際に機能性付与粒子の凝集が起こったり、熱処理時に不織布全体を、不織布を構成する繊維表面が軟化する程度まで加熱する必要があるため、不織布の性状が変化したりするという問題があった。
本発明の目的は、上記従来技術が有していた問題点を解消し、高分子化合物成型品が元来有する性状を実質的に変化させることなく機能性付与粒子を担持させ、機能性を有する高分子化合物成型品を製造する方法を提供することにある。 The object of the present invention is to solve the problems of the prior art described above, and to support the functional particles without substantially changing the properties inherent in the polymer compound molded product, thus having functionality. It is providing the method of manufacturing a high molecular compound molded article.
本発明者らは上記の従来技術に鑑みて鋭意検討を重ねた結果、本発明に到達した。
すなわち、本発明の目的は、高分子化合物成型品と機能性付与粒子とを共存させた系に、圧縮力、衝撃力、摩砕力及びせん断力から選ばれる少なくとも一種をメカノケミカルなエネルギーとして付与することにより、高分子化合物成型品に機能性付与粒子を担持させる、機能性を有する高分子化合物成型品の製造方法によって達成することができる。
The inventors of the present invention have reached the present invention as a result of intensive studies in view of the above prior art.
That is, the object of the present invention is to impart at least one kind selected from compressive force, impact force, grinding force and shear force as mechanochemical energy to a system in which a polymer compound molded product and functionality-imparting particles coexist. By doing so, it can be achieved by a method for producing a polymer compound molded product having functionality in which the functional compound-imparted particles are supported on the polymer compound molded product.
本発明によれば、バインダーや熱処理を必要とすることなく、高分子化合物成型品に機能性付与粒子を担持することができるため、機能性付与粒子が有する機能と高分子化合物成型品が元来有する機能とを最大限発揮させることができる。 According to the present invention, the functional compound-imparted product can be supported on the polymer compound molded product without the need for a binder or heat treatment. The functions it has can be maximized.
また、メカノケミカルなエネルギーにより、機能性付与粒子の粉砕、又は粉砕及び解砕と同時に、機能性付与粒子の高分子化合物成型品への担持をも同時に行うこともでき、担持された機能性付与粒子の分散性が著しく向上するとともに微粒子化することができるので、機能が発揮される有効比表面積を増大させることができる。 In addition, the mechanochemical energy enables the functionalized particles to be pulverized, or simultaneously pulverized and pulverized, and the functionalized particles to be supported on the polymer compound molded product at the same time. Since the dispersibility of the particles is remarkably improved and the particles can be made into fine particles, the effective specific surface area where the function is exhibited can be increased.
以下、本発明について詳細に説明する。
本発明の製造方法においては、まず高分子化合物成型品と機能性付与粒子とを共存させた系とすることが必要である。
Hereinafter, the present invention will be described in detail.
In the production method of the present invention, it is necessary to first make a system in which a polymer compound molded product and functionally imparted particles coexist.
ここで、機能性粒子と共存させる高分子化合物成型品としては、機能付与しようとする高分子化合物成型品をいずれも用いることができ、ポリエステル系樹脂、脂肪族ポリアミド系樹脂、芳香族ポリアミド系樹脂、全芳香族ポリアミド系樹脂、ビニル系樹脂、ポリウレタン系樹脂、アクリル系樹脂及びポリオレフィン系樹脂等からなる繊維、フィルムなどを好ましい例として挙げることができる。 Here, as the polymer compound molded product coexisting with the functional particles, any of the polymer compound molded products to be imparted with functions can be used, such as polyester resins, aliphatic polyamide resins, aromatic polyamide resins. Preferred examples include fibers, films and the like made of wholly aromatic polyamide resins, vinyl resins, polyurethane resins, acrylic resins and polyolefin resins.
繊維の形態としては、いずれも採用することができ、フィラメント形態やステープル形態、これらの集合したヤーン形態、織物形態、編物形態、不織布形態、フェルト形態等の繊維集合体形態、また繊維集合体を構成する繊維の一部が固着された繊維構造体形態をとることができ、これらは前述の素材を混合したものであってもよい。また、繊維断面形状は、通常の中実断面のほか、断面形状の異なる異形断面であってもよく、例えば中空断面、三角断面、四角断面、中実断面が２つ以上組み合わさって形成される幅広断面などの異形断面形状や、異種ポリマーを組み合わせた繊維としてもよく、例えば、芯鞘型複合繊維、サイド・バイ・サイド型複合繊維や混合紡糸繊維としてもよい。またこれら異種ポリマーの組み合わせにより繊維を異形断面形状としてもよい。 As the fiber form, any of them can be adopted, such as filament form, staple form, aggregated yarn form, woven form, knitted form, non-woven form, felt form, etc., and fiber aggregate form. It can take the form of a fiber structure in which some of the constituent fibers are fixed, and these may be a mixture of the aforementioned materials. Further, the fiber cross-sectional shape may be an ordinary solid cross-section, or an irregular cross-section having a different cross-sectional shape, for example, a combination of two or more hollow cross-sections, triangular cross-sections, square cross-sections, and solid cross-sections. It may be an irregular cross-sectional shape such as a wide cross-section, or a fiber combining different polymers, for example, a core-sheath type composite fiber, a side-by-side type composite fiber, or a mixed spun fiber. Further, the fiber may have an irregular cross-sectional shape by a combination of these different polymers.
フィルムの形態としては、通常の面状体以外にも、表面に微多孔を多数有するものや、複数の面状体が貼り合わせたものを用いることが出来る。 As a form of the film, in addition to a normal planar body, a film having a large number of micropores on the surface or a laminate of a plurality of planar bodies can be used.
他方、本発明において上記高分子化合物成型品と共存させる機能性付与粒子としては、特に制限はなく、様々なものを用いることができ、例えば、酸化チタン、酸化アルミニウム、酸化ジルコニウム、酸化亜鉛等の金属酸化物や、金、白金、銀、鉄、アルミニウム、ステンレス、銅、ニッケル、マンガン等の金属類、ポリエチレン、ポリスチレン、ポリプロピレン、ポリエステル、ポリフェニレンスルサイド等の合成樹脂類などを用いることが出来る。 On the other hand, in the present invention, there are no particular limitations on the functional particles that coexist with the polymer compound molded product, and various types of particles can be used, such as titanium oxide, aluminum oxide, zirconium oxide, and zinc oxide. Metal oxides, metals such as gold, platinum, silver, iron, aluminum, stainless steel, copper, nickel, and manganese, and synthetic resins such as polyethylene, polystyrene, polypropylene, polyester, and polyphenylene sulfide can be used.
本発明においては、上述した高分子化合物成型品と機能性粒子とが共存された系にメカノケミカルなエネルギーを付与するが、このための装置としては、粉砕ボールを用いた粉砕装置を用いることができ、具体的には遊星型ボールミル、転動式ボールミル、振動式ボールミル等を挙げることができるが、圧縮力、衝撃力、摩砕力及びせん断力から選ばれる少なくとも一種を付与することができる限り、どのような手段を用いても良い。 In the present invention, mechanochemical energy is imparted to a system in which the above-described polymer compound molded product and functional particles coexist, and as a device for this purpose, a pulverizer using a pulverized ball may be used. Specific examples include a planetary ball mill, a rolling ball mill, a vibration ball mill, etc. As long as at least one selected from a compressive force, an impact force, a grinding force, and a shear force can be applied. Any means may be used.
本発明の製造方法は、担持処理する高分子化合物成型品の形態や処理量に応じて、回分式に処理しても連続式に処理してもどちらでもよい。 The production method of the present invention may be processed batchwise or continuously, depending on the form of the polymer compound molded product to be supported and the amount of treatment.
回分式で担持処理を行う場合は、使用形態に応じた形状に成型した高分子化合物成型品を容器内に固定し、該容器内に必要量の機能性付与粒子とメディアとを投入し、高分子化合物成型品に損傷が及ばない程度のメカノケミカルなエネルギーが付与できるように容器に外力を付加すればよく、容器に負荷する外力としては、容器を回転させる方法や振動させる方法など、使用する装置に応じた方法を選択すればよい。 When carrying the support in a batch system, a polymer compound molded product molded into a shape according to the usage form is fixed in a container, and the required amount of functional particles and media are put into the container. It is only necessary to apply external force to the container so that mechanochemical energy that does not damage the molecular compound molded product can be applied. The external force applied to the container can be a method of rotating the container or vibrating it. What is necessary is just to select the method according to an apparatus.
該メディアとしては、ジルコニアビーズ、ガラスビーズ等の粉砕用ボールメディアが好ましく使用されるが、圧縮力、衝撃力、摩砕力及びせん断力から選ばれる少なくとも一種を付与することができる限り、いずれを採用することもできる。また、機能性付与粒子自体がメディアとしての機能も持ちうる場合は、別途メディアを投入する必要はないが、担持後粒子の耐脱落性を向上させるためには高比重のメディアを投入するほうが好ましい。 As the media, ball media for grinding such as zirconia beads and glass beads are preferably used. As long as at least one selected from compressive force, impact force, grinding force and shearing force can be applied, any of them can be used. It can also be adopted. In addition, when the functionalized particles themselves can also function as media, it is not necessary to add media separately, but in order to improve the drop-off resistance of particles after loading, it is preferable to introduce media with high specific gravity. .
担持処理に用いる容器としては、ジルコニア製ポットや超高分子量ポリエチレン製ポットなどが好ましく使用される。更に、カートリッジフィルターのように、繊維状の高分子化合物成型品を容器内に固定して使用する製品に機能性付与粒子を担持する場合、製品の容器自体を担持に用いる容器として使用することも可能である。この場合、フィルター形状に加工した繊維を予め製品の容器内に組み付けた後、機能性付与粒子とメディアとを容器内に投入して密封し、製品の容器自体にメカノケミカルなエネルギーを付与した後に余分な機能性付与粒子とメディアとを排出すれば、機能性付与粒子を担持したカートリッジフィルターを容易に製造することが可能である。 As the container used for the supporting treatment, a pot made of zirconia, a pot made of ultra high molecular weight polyethylene, or the like is preferably used. In addition, when the functionalized particles are supported on a product that is used by fixing a fibrous polymer compound molded product in a container, such as a cartridge filter, the product container itself may be used as a container used for supporting. Is possible.
