【産業上の利用分野】
本発明は、新規なフッ素含有ポリオルガノシロキサン化合物に関する。
【0002】
【従来の技術】
従来、1分子中に炭素原子数3以上の直鎖または分岐状の1価アルキル基またはアルケニル基及び炭素原子数4以上のパーフルオロアルキル基含有官能基を有する含フッ素ポリオルガノシロキサン化合物は 特開昭58−52352号公報、特開昭56−41256号公報、特開平1−282267号公報、特開平4−36388号公報において開示されている。
【0003】
しかし、1分子中に極性原子団を有する2価の連結基を介して炭素原子数3以上の直鎖または分岐状の1価アルキル基またはアルケニル基及び炭素原子数4以上のパーフルオロアルキル基含有官能基を有する含フッ素ポリオルガノシロキサン化合物は未だ知られていない。
【0004】
【発明が解決しようとする課題】
従って本発明は、上記化合物を提供することを目的とする。
【0005】
【課題を解決するための手段】
すなわち、本発明は、分子中に一般式(I)で表される繰り返し単位及び一般式(II)で表される繰り返し単位を有し、分子量が3,000〜1,000,000であることを特徴とするポリオルガノシロキサン化合物を提供するものである。

本発明の新規含フッ素ポリオルガノシロキサン化合物の一般式(II)中のRは樹脂用表面改質剤して使用する場合、樹脂との相溶性、機能の持続性、耐久性の点から炭素原子数3以上の直鎖または分岐状の1価アルキル叉はアルケニル基である必要があり、この中、炭素数14〜22の直鎖または分岐状の1価アルキル叉はアルケニル基が好ましい。具体的にはC1429−、C1531−、C1731−、C1733、−C1735−、C1837−、C2143−、C2245−等が例示される。

で表わされるパーフルオロアルキル基(nは4以上の整数、mは1叉は2、Rは水素原子叉は炭素原子数1〜10のアルキル基)]を示すが、このパーフルオロアルキル基は本発明に係るポリオルガノシロキサン化合物を樹脂用表面改質剤として使用する場合に表面配向性と低濃度での性能を発現するために重要である。パーフルオロアルキル基中の炭素原子数nは原料の入手しやすさを考慮すると4〜16が好ましく、特に6〜10がより好ましい。
【0018】
またXは、極性原子団を有する2価の連結基であるが、極性原子団の種類は特に限定するものではなく、例えば−CHCHO−CHC(OH)CHO−、−O−CHCH(OH)CHO−、−NHCONH−、−NHRNHCONH−、−NHSO−、−NHRNHSO−及び−COO−(Rは炭素原子数1〜10のアルキレン基を表す)等が挙げられる。これらの極性原子団を有する2価の連結基も本発明のポリオルガノシロキサン化合物を樹脂用表面改質剤として使用する場合に表面配向性と低濃度での性能を発現するために重要である。
【0019】
また、Rは炭素原子数1〜10の2価アルキレン基であるが、原料入手の都合上1〜4が好ましい。次にp,q,rの関係としてp+q≧r/100であることが望ましく、特にp+q≧r/50が好ましい。p+q≦r/100では、本発明のポリオルガノシロキサン化合物を樹脂用表面改質剤として使用した場合、改質効果が減少する。更にp,q,rの関係として0.1≦p/q≦10であることが望ましく、特に0.1≦p/q≦1が好ましい。0.1≧p/q≧10では樹脂との相溶性、改質機能の持続性、耐久性が減少する。
【0020】
また本発明に係る新規フッ素含有ポリオルガノシロキサン化合物の分子量は3,000〜1000,000であり、好ましくは5,000〜10,000である。表面改質剤として使用した場合、新規フッ素含有ポリオルガノシロキサン化合物の分子量が5,000未満の場合は、その効果が減少し、10,000を越える場合には、樹脂との相溶性、改質機能の持続性、耐久性等が減少し、好ましくない。

−NHCONH−叉は−NHRNHCONH−叉は−NHSO−叉は −NHRNHSO−(Rは炭素原子数1〜10の2価のアルキレン基を表す)等を有する一般式(VI)で示されるポリオルガノシロキサン化合物が得られる。 但し、Rf−SOF等の酸ハロゲン化物は、反応により生成するフッ酸等がシリコーン側鎖のアミノ基と反応してしまうため、この酸と反応する受酸剤を反応系内に添加することが望ましい。受酸剤としては、例えばトリエチルアミン等の3級アミンが用いられる。

Rf−SOF等の酸ハロゲン化物とR−NCO等のイソシアネート化合物の具体例としては、次のような化合物が挙げられる。

【0057】
尚、一般式(IV)示される各種反応性基を有するポリオルガノシロキサン化合物の粘度としては、10000cst/25℃以下であり、好ましくは6000cst/25℃以下が望ましい。粘度が10000cst/25℃を越える場合、本発明に係る含フッ素ポリオルガノシロキサン化合物と反応に使用する溶剤との相溶性が低下し製造上問題が生じ、樹脂用表面改質剤として使用する場合表面改質効果が低下するためである。
【0058】
こうして得られた本発明に係る新規フッ素含有ポリオルガノシロキサン化合物は、特に用途は限定されないが、各種素材並びに基材に対し塗布した場合又は各種素材並びに基材に内添した場合(基材と相溶するとき)、耐擦傷性、耐油性、平滑性、減摩性、撥水撥油性、耐水性、防湿性、防錆性、防汚性、剥離性、離型性、低吸水性等に優れた表面を形成することから、各種素材並びに基材に対する保護剤や表面処理剤、内添剤として単独又は構成要素として使用することが可能である。
【0059】
例えば、撥水撥油剤、潤滑剤、潤滑剤用添加剤、防錆剤、防汚剤、耐油剤、耐水化剤、剥離剤、離型剤、防湿剤、塗料用・コ−ティング剤用添加剤、塗料用・コ−ティング剤用レベリング剤、ワックス併用による艶出し剤、界面活性剤、各種繊維、金属、紙、木材、そしてガラス、セラミック、陶器や磁器や鉱石等の無機物等の保護剤、基材上に蒸着された強磁性合金(鉄、コバルト及び/又はニッケルを主成分とし、少量のアルミニウム、シリコン、クロム、マンガン、モリブデン、チタン、各種重金属、希土類金属等を含むもの)または微量酸素存在下で鉄、コバルト、クロム等の磁性材料をポリエステル等のプラスチックフィルムに蒸着した磁気テ−プ又は磁気ディスクの磁性層等の保護皮膜や、減摩性が特に要求される磁気テ−プ、磁気ディスク、光磁気ディスク、フロッピ−ディスク等の磁気記録媒体の表面及び背面処理剤としても好適である。
【0060】
また特に用途を限定するものではないが、本発明に係る新規フッ素含有ポリオルガノシロキサン化合物を樹脂又はゴム用の表面改質剤として用いる場合には、成形用樹脂に適宜加えられる他の添加剤と同様に添加するか、叉は樹脂成形品表面に塗布するという方法で用いられるが、好ましくは成形用樹脂に添加することが望ましい。
【0061】
成形用樹脂に添加する場合の添加量は、樹脂の種類、改質の目的、樹脂とその添加されるポリオルガノシロキサンとの相溶性にもよるが、一般的には成形用樹脂100重量部に対して0.005〜20重量部であり、好ましくは0.01〜10重量部とされる。0.005重量部より少ないと効果は小さくなり一方20重量部より多くしても、もはやそれ以上の効果は望めないばかりか、場合によってはブルーミング、成形品の強度低下等が生じるようになる。
【0062】
樹脂成形品に添加した場合、成形品表面に非常に優れた表面潤滑性能を付与できるが、特にオレフィン系樹脂等の非極性樹脂に添加する場合には成形用樹脂100重量部に対して0.05〜0.1重量部の非常に少ない添加量で効果が期待できる。
【0063】
本発明に係る新規ポリオルガノシロキサン化合物の成形用樹脂への配合方法としては、新規ポリオルガノシロキサン化合物を溶剤(溶剤は成形用樹脂に悪影響をおよぼさなければ特に限定はない)に分散または溶解してから添加し均一混合後脱溶剤する方法または直接成形用樹脂に添加し混練する方法または予めマスターバッチを作製しておき、次いでマスターバッチを成形用樹脂に添加して均一に混合する方法が挙げられる。
【0064】
一方、樹脂成形品の表面に塗布する場合には、ポリオルガノシロキサンをそのまま塗布してもよいが、通常は塗布操作を容易にするために適当な有機溶剤に予め希釈しておくことがよい。この有機溶剤としては、例えばメチルセロソルブ、エチルセロソルブ、カルビトール等のグリコール類、ベンゼン、トルエン、キシレン等の芳香族炭化水素類、アセトン、メチルエチルケトン、メチルイソブチルケトン等のケトン類、酢酸エチル、酢酸ブチル等のエステル類、1、1、1トリフルオロトリクロロエタン等のフッ化炭化水素類等が挙げられる。なおこれらの有機溶剤は1種類に限らず、2種類以上併用してもよい。
【0065】
改質の対象となる樹脂、ゴムは特に限定するものではないが、特に代表的な樹脂、ゴムとしては、ポリエチレン樹脂、ポリプロピレン樹脂、エチレン−プロピレン−ジエンゴム、エチレン−プロピレンゴム、イソプレンゴム、ブチルゴム、スチレン−ブタジエンゴム、ポリブタジエンゴム、NBRゴム、天然ゴム、フッ素ゴムクロロプレンゴム、ABS樹脂、AS樹脂、SB樹脂、ポリアセタール樹脂、ポリスチレン樹脂、塩化ビニル−酢酸ビニル共重合体樹脂、ポリメチルメタクリレート樹脂、飽和ポリエステル樹脂、ポリアミド樹脂、ポリウレタン樹脂、エポキシ樹脂、フェノール樹脂、アミノ樹脂、ポリカーボネート樹脂、ポリフッ化オレフィン樹脂、セルロース樹脂、アルキッド樹脂、メラミン樹脂等が挙げられ、いずれも効果的な樹脂の改質効果を得ることができる。本発明に係る樹脂用改質剤により特に絶大なる樹脂の改質効果を得るには、特にポリエチレン、エチエレン−プロピレン−ジエンゴム、エチレン−プロピレンゴム等のオレフィン系樹脂またはゴムが好ましい。
【0066】
これらの樹脂、ゴムには、通常用いられている充填剤、可塑剤、熱安定剤、酸化防止剤、難燃剤、紫外線吸収剤、帯電防止剤、加硫剤、加硫促進剤等を配合してもよい。

The viscosity of the polyorganosiloxane compound having various reactive groups represented by the general formula (IV) is 10,000 cst / 25 ° C. or less, and preferably 6000 cst / 25 ° C. or less. When the viscosity exceeds 10,000 cst / 25 ° C., the compatibility between the fluorine-containing polyorganosiloxane compound according to the present invention and the solvent used in the reaction is reduced, causing a problem in production. This is because the reforming effect is reduced.
[0058]
The thus obtained novel fluorine-containing polyorganosiloxane compound according to the present invention is not particularly limited in use, but may be applied to various materials and substrates, or internally added to various materials and substrates (substrate and base).

In addition, the use is not particularly limited, but when the novel fluorine-containing polyorganosiloxane compound according to the present invention is used as a surface modifier for a resin or a rubber, other additives appropriately added to a molding resin may be used. It is used in the same manner, or it is used in such a manner that it is applied to the surface of a resin molded product.
[0061]
The amount of the resin to be added to the molding resin depends on the type of the resin, the purpose of the modification, and the compatibility of the resin and the polyorganosiloxane to be added. It is 0.005 to 20 parts by weight, preferably 0.01 to 10 parts by weight. If the amount is less than 0.005 parts by weight, the effect is reduced, while if the amount is more than 20 parts by weight, no more effect can be expected anymore, and in some cases, blooming, reduction in strength of a molded article, and the like occur.
[0062]
When added to a resin molded product, very good surface lubrication performance can be imparted to the surface of the molded product. The effect can be expected with a very small addition amount of from 0.5 to 0.1 part by weight.

On the other hand, when the polyorganosiloxane is applied to the surface of a resin molded product, the polyorganosiloxane may be applied as it is, but usually, it is preferable to dilute it in an appropriate organic solvent in advance to facilitate the application operation. Examples of the organic solvent include glycols such as methyl cellosolve, ethyl cellosolve and carbitol; aromatic hydrocarbons such as benzene, toluene and xylene; ketones such as acetone, methyl ethyl ketone and methyl isobutyl ketone; ethyl acetate and butyl acetate. And fluorinated hydrocarbons such as 1,1,1 trifluorotrichloroethane. Note that these organic solvents are not limited to one type, and two or more types may be used in combination.
