Description

本発明は、防汚性を必要とする各種の被処理基材の表面に、防汚層を形成する方法に関するものである。さらに詳しくは、各種の被処理基材上に防汚層を速やかに定着させる方法である。   The present invention relates to a method for forming an antifouling layer on the surface of various substrates to be treated that require antifouling properties. More specifically, the antifouling layer is quickly fixed on various substrates to be treated.
従来、光学レンズ、眼鏡レンズ、カメラや双眼鏡などのレンズには、光の反射を減らし、光の透過性を高めるために、通常、その表面に反射防止処理が施されている。これらの光学部材を人が使用することによって、指紋、皮脂、汗、化粧品などの汚れが付着する場合が多い。   Conventionally, lenses such as optical lenses, spectacle lenses, cameras, and binoculars are usually subjected to antireflection treatment on the surface in order to reduce light reflection and increase light transmittance. When these optical members are used by humans, dirt such as fingerprints, sebum, sweat, cosmetics and the like often adhere.
一般に、反射防止膜の表面エネルギーは約60J/mと大きいために、そのような汚れが付着しやすく、かつ、微細な凹凸があるため除去することが容易ではない。また、そのような汚れが付着した部分だけ高反射となり、汚れが目立つため問題があった。 In general, since the surface energy of the antireflection film is as large as about 60 J / m 2, it is difficult to remove such dirt because it easily adheres and has fine irregularities. Further, only the portion where such dirt is attached becomes highly reflective, and there is a problem because the dirt is conspicuous.
そこで、これら汚れの問題を解決する手段として、汚れが付着しにくく、付着しても拭き取りやすい性能を持つ防汚層を設ける工夫が考案されている。   Therefore, as a means for solving these problems of contamination, a device has been devised to provide an antifouling layer having a performance that makes it difficult for dirt to adhere and easily wipes it off.
例えば、特開昭64−86101号公報には、基材の表面に、主として二酸化珪素からなる反射防止膜を設け、更にその表面に有機珪素置換基を含む化合物で処理した耐汚染性、耐擦傷性の反射防止膜物品が提案されている。   For example, in Japanese Patent Application Laid-Open No. 64-86101, an antireflection film mainly composed of silicon dioxide is provided on the surface of a base material, and the surface is further treated with a compound containing an organosilicon substituent. Antireflective film articles have been proposed.
特開平4−338901号公報には、同様に基材表面に末端シラノール有機ポリシロキサンを被膜した耐汚染性、耐擦傷性のCRTフィルターが提案されている。   Japanese Patent Application Laid-Open No. 4-338901 proposes a CRT filter having stain resistance and scratch resistance, in which a terminal silanol organopolysiloxane is similarly coated on the surface of a substrate.
また、特公平6−29332号公報には、プラスチック表面にポリフルオロアルキル基を含むモノおよびジシラン化合物およびハロゲン、アルキルまたはアルコキシのシラン化合物とからなる反射防止膜を有する低反射率および防汚性のプラスチックが提案されている。   Japanese Patent Publication No. 6-29332 discloses a low reflectance and antifouling property having an antireflection film comprising a mono and disilane compound containing a polyfluoroalkyl group on the plastic surface and a halogen, alkyl or alkoxy silane compound. Plastic has been proposed.
更に、特開平7−16940号公報には、パーフルオロアルキル(メタ)アクリレートとアルコキシシラン基を有する単量体との共重合体を二酸化珪素を主とする光学薄膜上に形成した光学物品が提案されている。   Further, JP-A-7-16940 proposes an optical article in which a copolymer of perfluoroalkyl (meth) acrylate and a monomer having an alkoxysilane group is formed on an optical thin film mainly composed of silicon dioxide. Has been.
しかしながら、従来の防汚層の形成技術において、防汚層を成膜後、その耐防汚性、耐摩耗性、耐溶剤性等を最大限にするまで数時間、場合によっては数日という長時間を要し、その間では汚れや傷が入りやすく、また、他の物品と接触すると、防汚層の一部が転写し、防汚層が剥離してしまうという問題があった。   However, in the conventional antifouling layer formation technology, after the antifouling layer is formed, the antifouling property, abrasion resistance, solvent resistance, etc. are maximized for several hours, sometimes several days. In the meantime, dirt and scratches are likely to occur, and when it comes into contact with other articles, a part of the antifouling layer is transferred and the antifouling layer is peeled off.
本発明は、前述のような従来技術の課題を解決しようとするものであり、本発明の目的は、各種光学部材などの被処理基材の表面を前処理を行うことによって、耐防汚性、耐擦傷性、耐溶剤性等に優れた防汚層を短時間に形成することができ防汚層の形成方法を提供することである。   The present invention is intended to solve the above-described problems of the prior art, and an object of the present invention is to provide antifouling resistance by pretreating the surface of a substrate to be treated such as various optical members. Another object of the present invention is to provide a method for forming an antifouling layer that can form an antifouling layer excellent in scratch resistance, solvent resistance and the like in a short time.

本発明を詳細に説明する。
防汚層を被処理基材上に成膜する場合、パーフルオロポリエーテル基を含有する有機シラン化合物からなる防汚剤が使用される。
前記有機シラン化合物は、下記一般式(1)で表される化合物またはその重合体が好適である。
−(OC−O−(CF−(CH−O−(CH−Si(R)・・・(1)
The present invention will be described in detail.
When the antifouling layer is formed on the substrate to be treated, an antifouling agent composed of an organic silane compound containing a perfluoropolyether group is used.
The organic silane compound is preferably a compound represented by the following general formula (1) or a polymer thereof.
R f - (OC 3 F 6 ) n -O- (CF 2) m - (CH 2) l -O- (CH 2) s -Si (R) 3 ··· (1)
一般式(1)において、Rは炭素数1〜16の直鎖状または分岐状パーフルオロアルキル基であり、特に、CF−、C−、C−が好ましい。Rは加水分解基であり、−Cl、−Br、−I、−OR、−OOCR、−OC(R)C=C(R、−ON=C(R、−ON=CR、−N(R、−RNOCR等が好ましい。 In the general formula (1), R f is a linear or branched perfluoroalkyl group having 1 to 16 carbon atoms, in particular, CF 3 -, C 2 F 5 -, C 3 F 7 - is preferred. R is a hydrolyzable group, -Cl, -Br, -I, -OR 1, -OOCR 1, -OC (R 1) C = C (R 2) 2, -ON = C (R 1) 2, -ON = CR 3, -N (R 2) 2, -R 2 NOCR 1 and the like are preferable.
但し、Rはアルキル基等の炭素数1〜10の脂肪族炭化水素基、またはフェニル基等の炭素数6〜20の芳香族炭化水素基、Rは水素原子またはアルキル基等の炭素数1〜5の脂肪族炭化水素基、Rはアルキリデン基等の炭素数3〜6の二価の脂肪族炭化水素基である。 Where R 1 is an aliphatic hydrocarbon group having 1 to 10 carbon atoms such as an alkyl group, or an aromatic hydrocarbon group having 6 to 20 carbon atoms such as a phenyl group, and R 2 is a carbon number such as a hydrogen atom or an alkyl group. 1-5 aliphatic hydrocarbon group, R 3 is a divalent aliphatic hydrocarbon group having 3 to 6 carbon atoms such as alkylidene groups.
上記の有機シラン化合物中の加水分解基は、1種類のみならず、2種類以上の混合系として用いることも可能である。特に、−OCH、−OC、−OOCCH、−NHが好ましい。また、nは1〜50の整数、mは0〜3の整数、lは0〜3の整数、sは0〜6の整数、但し、6≧m+l>0である。 The hydrolyzable group in the organosilane compound can be used not only as one type but also as a mixed system of two or more types. In particular, -OCH 3, -OC 2 H 5 , -OOCCH 3, -NH 2 are preferred. N is an integer of 1 to 50, m is an integer of 0 to 3, l is an integer of 0 to 3, s is an integer of 0 to 6, provided that 6 ≧ m + 1> 0.
作業環境や、膜厚の制御の点から、防汚層形成時には希釈溶媒を用いないPVD法によることが好ましく、特に真空蒸着法によることが好ましい。該方法では、前記防汚剤を1Pa以下の圧力において加熱し、蒸発させ、被処理基材上に形成する。   From the viewpoint of working environment and control of the film thickness, it is preferable to use a PVD method that does not use a diluting solvent when forming an antifouling layer, and it is particularly preferable to use a vacuum deposition method. In this method, the antifouling agent is heated at a pressure of 1 Pa or less, evaporated and formed on a substrate to be treated.
加熱方法としては抵抗加熱法、電子線加熱法、光加熱法、イオンビーム加熱法、高周波加熱法のような方法が有効である。PVD法によると、従来困難であった防汚層の膜厚をオングストロームオーダーで正確に制御することができる。   As the heating method, methods such as a resistance heating method, an electron beam heating method, a light heating method, an ion beam heating method, and a high frequency heating method are effective. According to the PVD method, the film thickness of the antifouling layer, which has been difficult in the past, can be accurately controlled in angstrom order.
前記有機シラン化合物を含有する防汚剤は、被処理基材表面のOH基と有機シラン化合物の加水分解可能な基が反応して加水分解を起こし、化学結合を形成すると考えられている。しかし、一般的に防汚層と被処理基材表面との間の加水分解反応は遅く、防汚層が完全に定着し、最大限の耐防汚性、耐擦傷性、耐溶剤性等が生じるまでに数時間から数十日という時間を要する。   The antifouling agent containing the organic silane compound is considered to form a chemical bond by causing the OH group on the surface of the substrate to be treated and the hydrolyzable group of the organic silane compound to react to cause hydrolysis. However, in general, the hydrolysis reaction between the antifouling layer and the surface of the substrate to be treated is slow, the antifouling layer is completely fixed, and maximum antifouling resistance, scratch resistance, solvent resistance, etc. It takes several hours to tens of days to occur.
一方、本発明の前処理方法である高周波放電プラズマ法、電子ビーム法、イオンビーム法、蒸着法、スパッタリング法、アルカリ処理法、酸処理法、コロナ処理法、大気圧グロー放電プラズマ法等は、被処理基材表面をクリーニングするだけではなく、表面の分子同士の結合を切り離し、活性な表面を作り出すことができるため、有機シラン化合物を含有する防汚剤からなる防汚層が容易に定着しやすい被処理基材表面を作り出すことができる。   On the other hand, the pretreatment method of the present invention is a high frequency discharge plasma method, an electron beam method, an ion beam method, a vapor deposition method, a sputtering method, an alkali treatment method, an acid treatment method, a corona treatment method, an atmospheric pressure glow discharge plasma method, etc. In addition to cleaning the surface of the substrate to be treated, it is possible to create an active surface by separating the bonds between the molecules on the surface, so that an antifouling layer comprising an antifouling agent containing an organosilane compound can be easily fixed. An easy-to-process substrate surface can be created.
被処理基材は、光学レンズ、眼鏡レンズ、カメラや双眼鏡、または他の光学装置のレンズ、ビーム・スプリッタ、プリズム、鏡、窓ガラス、反射防止膜、光学フィルターなどの光学部材に対して特に有効である。   The treated substrate is particularly effective for optical members such as optical lenses, eyeglass lenses, lenses for cameras and binoculars, or other optical devices, beam splitters, prisms, mirrors, window glass, antireflection films, optical filters, etc. It is.
以下、本発明の実施例を説明するが、これらに限定されるものではない。   Examples of the present invention will be described below, but the present invention is not limited thereto.
