同種または異種の樹脂部品を接着する方法の一つに、加熱した治具で樹脂部品の接着面を溶解させた後に、樹脂部品同士を圧着する熱板溶着法がある。熱板溶着は、接着剤を必要とせず、また超音波接合等よりも簡便であるという特徴がある。   One method of bonding the same or different types of resin parts is a hot plate welding method in which the bonding surfaces of the resin parts are melted with a heated jig and then the resin parts are pressure-bonded to each other. Hot plate welding does not require an adhesive and is characterized by being simpler than ultrasonic bonding or the like.

熱板溶着では、加熱後に治具から樹脂を引き離すときに、治具の表面に溶融した樹脂が付着して糸引きが生じることがある。この糸引きは成型品の品質に影響を与えるので、極力防止することが望ましい。そこで、従来から熱板溶着に使用する治具の表面に離型処理を施すことが行われている。   In hot plate welding, when the resin is pulled away from the jig after heating, the molten resin may adhere to the surface of the jig and cause stringing. Since this stringing affects the quality of the molded product, it is desirable to prevent it as much as possible. Therefore, a mold release process has been conventionally performed on the surface of a jig used for hot plate welding.

離型処理の一つに、処理対象に硬質金属からなる溶射層を設け、その溶射層上にＰＴＦＥ（ポリテトラフルオロエチレン）またはＰＦＡ（テトラフルオロエチレン・パーフルオロアルコキシエチレン共重合体）のようなフッ素樹脂からなる離型層を設ける方法がある。また、基体の表面にシリカ下地層を形成した後に、フッ化炭素系化合物を含む溶媒を塗布して、耐久性が良く撥水撥油性に優れた被膜を作る方法が知られている（例えば、特許文献１）。   As one of the mold release treatments, a thermal spray layer made of a hard metal is provided on the object to be treated, and PTFE (polytetrafluoroethylene) or PFA (tetrafluoroethylene / perfluoroalkoxyethylene copolymer) is applied on the thermal spray layer. There is a method of providing a release layer made of a fluororesin. Moreover, after forming a silica underlayer on the surface of the substrate, a method is known in which a solvent containing a fluorocarbon-based compound is applied to form a film having excellent durability and water and oil repellency (for example, Patent Document 1).

しかしながら、上記のようにフッ素樹脂からなる離型層を溶着用の治具表面に形成した場合、溶着による熱と圧力によって離型層が徐々に劣化してしまう。同様に、フッ化炭素系化合物による離型層を溶着用の治具表面に形成した場合も、溶着時の高い圧力や摺動により表面が摩耗し、離型層の撥水撥油性が徐々に失われてしまう。このように離型層が劣化した場合、溶着治具に対して再度離型処理を施す必要が生じるので、溶着治具の稼働率が低下しコストも増大するという問題がある。   However, when the release layer made of fluororesin is formed on the surface of the welding jig as described above, the release layer gradually deteriorates due to heat and pressure due to welding. Similarly, when a release layer made of a fluorocarbon compound is formed on the surface of a welding jig, the surface is worn by high pressure and sliding during welding, and the water and oil repellency of the release layer gradually increases. It will be lost. When the release layer is deteriorated as described above, it is necessary to perform the release treatment again on the welding jig, which causes a problem that the operating rate of the welding jig is lowered and the cost is increased.

本発明はこうした状況に鑑みてなされたものであり、その目的は、フッ化炭素系化合物からなる離型層を有する溶着治具等の金属部品において、離型層の耐久性を向上させる技術を提供することにある。   The present invention has been made in view of such a situation, and an object of the present invention is to improve the durability of the release layer in a metal part such as a welding jig having a release layer made of a fluorocarbon compound. It is to provide.

上記課題を解決するために、本発明のある態様の熱板溶着用治具は、樹脂部品の熱板溶着用の治具であって、樹脂部品の熱板溶着対象部位と接触するように成形された金属層と、金属層の上に積層された耐摩耗性を有する窒化物系セラミックス薄膜と、窒化物系セラミックス薄膜の上に積層されたフッ化炭素系化合物の薄膜からなる離型層と、を備える。   In order to solve the above-mentioned problems, a hot plate welding jig according to an aspect of the present invention is a jig for hot plate welding of resin parts, and is formed so as to be in contact with a hot plate welding target part of the resin parts.

この態様によると、離型層の下側に窒化物系セラミックス薄膜を形成することで、熱板溶着用治具の硬度および耐久性を高めることができる。   According to this aspect, the hardness and durability of the hot plate welding jig can be increased by forming the nitride ceramic thin film below the release layer.

窒化物系セラミックス薄膜と離型層との間に、活性化処理により窒化物系セラミックスの反応基とフッ化炭素系化合物の反応基とが結合した活性層が形成されていてもよい。これによると、活性化処理によって、非活性時よりも多量のフッ化炭素系化合物を窒化物系セラミックス薄膜に結合させることができる。   An active layer in which a reactive group of the nitride-based ceramic and a reactive group of the fluorocarbon-based compound are bonded may be formed between the nitride-based ceramic thin film and the release layer by an activation treatment. According to this, a larger amount of the fluorocarbon-based compound can be bonded to the nitride-based ceramic thin film by the activation treatment than when it is inactive.

活性化処理が、窒化物系セラミックス薄膜に対するプラズマ処理であってもよい。   The activation treatment may be a plasma treatment for the nitride ceramic thin film.

フッ化炭素系化合物が、パーフルオロポリエーテル変性アミノシランまたはパーフルオロポリエーテル変性ポリシラザンであってもよい。これによると、熱板溶着用治具の表面に撥水撥油性に優れた薄膜を形成して、溶着時の樹脂の付着を抑制することができる。   The fluorocarbon-based compound may be perfluoropolyether-modified aminosilane or perfluoropolyether-modified polysilazane. According to this, a thin film excellent in water and oil repellency can be formed on the surface of the hot plate welding jig, and adhesion of the resin during welding can be suppressed.

本発明の別の態様は、熱板溶着用治具の製造方法である。この方法は、樹脂部品の熱板溶着対象部位と接触するように成形された金属層を準備する工程と、金属層の上に耐摩耗性を有する窒化物系セラミックス薄膜を形成する工程と、窒化物系セラミックス薄膜の表面を活性化する活性化処理を行う工程と、窒化物系セラミックス薄膜が活性化された状態で、その上にフッ化炭素系化合物の薄膜からなる離型層を形成する工程と、を含む。   Another aspect of the present invention is a method for manufacturing a hot plate welding jig. This method includes a step of preparing a metal layer formed so as to be in contact with a hot plate welding target portion of a resin component, a step of forming a nitride ceramic thin film having wear resistance on the metal layer, A step of activating the surface of the material-based ceramic thin film, and a step of forming a release layer made of a fluorocarbon-based compound thin film on the activated state of the nitride-based ceramic thin film And including.

本発明のさらに別の態様は、金属層と、金属層の上に積層された耐摩耗性を有する窒化物系セラミックス薄膜と、窒化物系セラミックス薄膜の上に積層されたフッ化炭素系化合物の薄膜からなる離型層と、を備え、窒化物系セラミックス薄膜と離型層との間に、活性化処理により窒化物系セラミックスの反応基とフッ化炭素系化合物の反応基とが結合した活性層が形成された金属部材である。   Still another embodiment of the present invention is a metal layer, a wear-resistant nitride-based ceramic thin film laminated on the metal layer, and a fluorocarbon-based compound laminated on the nitride-based ceramic thin film. A release layer composed of a thin film, and an activity in which a reactive group of the nitride ceramic and a reactive group of the fluorocarbon compound are bonded by an activation treatment between the nitride ceramic thin film and the release layer. A metal member in which a layer is formed.

本発明によれば、フッ化炭素系化合物からなる離型層を有する溶着治具等の金属部品において、離型層の耐久性を向上させることができる。   ADVANTAGE OF THE INVENTION According to this invention, durability of a mold release layer can be improved in metal parts, such as a welding jig which has a mold release layer which consists of a fluorocarbon type compound.

以下では、一例として車両用前照灯のレンズ部とボディ部との溶着を例として本発明の実施形態を説明する。しかしながら、二つの樹脂部品を溶着する任意の工程に本実施形態を利用することができる。   In the following, an embodiment of the present invention will be described taking welding of a lens part and a body part of a vehicle headlamp as an example. However, this embodiment can be used in any process for welding two resin parts.

図１は、一般的な熱板溶着の工程を説明する図である。まず、図１（ａ）に示すように、それぞれが樹脂部材であるレンズ部２４とボディ部２６を、レンズ受け治具２２とボディ受け治具２８にそれぞれセットする。レンズ部２４は例えばメタクリル樹脂またはアクリル樹脂であり、ボディ部２６は例えばＡＳ（アクリロニトリル・スチレン共重合体）樹脂またはＡＢＳ（アクリロニトリル・ブタジエン・スチレン共重合体）樹脂で形成される。   FIG. 1 is a diagram for explaining a general hot plate welding process. First, as shown in FIG. 1A, the lens portion 24 and the body portion 26, which are resin members, are set on the lens receiving jig 22 and the body receiving jig 28, respectively. The lens portion 24 is made of, for example, methacrylic resin or acrylic resin, and the body portion 26 is made of, for example, AS (acrylonitrile / styrene copolymer) resin or ABS (acrylonitrile / butadiene / styrene copolymer) resin.

図１（ｂ）に示すように、レンズ部２４の樹脂を加熱するためのレンズ熱板３０と、ボディ部２６の樹脂を加熱するためのボディ熱板３２とを両面に備えた溶着治具４０を、レンズ部２４およびボディ部２６の間に配置する。レンズ熱板は、例えば真鍮製であり、ボディ熱板は例えば鉄またはアルミ製である。レンズ熱板３０とボディ熱板３２は、加熱対象であるレンズ部２４、ボディ部２６の樹脂の種類に応じて、樹脂が溶融する温度以上に加熱される。一例として、レンズ熱板３０は４００°Ｃに、ボディ熱板３２は２００°Ｃに、それぞれ加熱される。また、ボディ熱板３２の表面には、テフロン加工が施されている。   As shown in FIG. 1B, a welding jig 40 having a lens heating plate 30 for heating the resin of the lens portion 24 and a body heating plate 32 for heating the resin of the body portion 26 on both surfaces. Is disposed between the lens portion 24 and the body portion 26. The lens hot plate is made of, for example, brass, and the body hot plate is made of, for example, iron or aluminum. The lens hot plate 30 and the body hot plate 32 are heated to a temperature equal to or higher than the temperature at which the resin melts, depending on the type of resin of the lens unit 24 and the body unit 26 that are the heating targets. As an example, the lens hot plate 30 is heated to 400 ° C., and the body hot plate 32 is heated to 200 ° C., respectively. The surface of the body hot plate 32 is subjected to Teflon processing.

続いて、図１（ｃ）に示すように、レンズ受け治具２２とボディ受け治具２８を、溶着治具４０に向けて移動させる。そして、レンズ部２４とレンズ熱板３０、およびボディ部２６とボディ熱板３２とがそれぞれ接触した状態で、レンズ受け治具２２とボディ受け治具２８とを適切な力で圧縮する。このとき、レンズ部２４とボディ部２６の所定の部位が、熱板の熱によって溶融する。   Subsequently, as shown in FIG. 1C, the lens receiving jig 22 and the body receiving jig 28 are moved toward the welding jig 40. Then, the lens receiving jig 22 and the body receiving jig 28 are compressed with an appropriate force in a state where the lens part 24 and the lens hot plate 30 and the body part 26 and the body hot plate 32 are in contact with each other. At this time, predetermined portions of the lens portion 24 and the body portion 26 are melted by the heat of the hot plate.

所定時間の経過後、図１（ｄ）に示すように、レンズ受け治具２２とボディ受け治具２８とを溶着治具４０から離し、図１（ｅ）に示すように、をレンズ部２４とボディ部２６の間から溶着治具４０を移動させる。   After the predetermined time has elapsed, as shown in FIG. 1D, the lens receiving jig 22 and the body receiving jig 28 are separated from the welding jig 40, and as shown in FIG. The welding jig 40 is moved from between the body portion 26 and the body portion 26.

続いて、図１（ｆ）に示すように、レンズ受け治具２２をボディ受け治具２８に向けて移動させ、レンズ部２４とボディ部２６の所定の部位を接触させ、適当な圧力を加えて両者を圧着する。最後に、図１（ｇ）に示すように、レンズ受け治具２２をボディ受け治具２８から離して、圧着されたレンズ部２４およびボディ部２６を取り出す。   Subsequently, as shown in FIG. 1 (f), the lens receiving jig 22 is moved toward the body receiving jig 28, a predetermined portion of the lens portion 24 and the body portion 26 is brought into contact, and an appropriate pressure is applied. And crimp them together. Finally, as shown in FIG. 1G, the lens receiving jig 22 is separated from the body receiving jig 28, and the pressure-bonded lens portion 24 and body portion 26 are taken out.

図２（ａ）は、図１で説明したレンズ部２４とボディ部２６の接合部２４ａ、２６ａの拡大図を示す。各接合部は、溶着時の沈みしろＫを考慮した長さに設定されている。図２（ｂ）はレンズ部２４とレンズ熱板３０との接触部分の拡大図であり、図２（ｃ）はボディ部２６とボディ熱板３２との接触部分の拡大図である。図２（ｄ）は、溶着後のレンズ部２４およびボディ部２６の接合部の部分拡大図であり、図１（ｇ）内のＨ部に対応している。図示するように、接合部２４ａ、２６ａには、溶着による発泡バリが形成される。   FIG. 2A shows an enlarged view of the joint portions 24a and 26a between the lens portion 24 and the body portion 26 described in FIG. Each joint is set to a length that takes into account the sinking margin K during welding. FIG. 2B is an enlarged view of a contact portion between the lens portion 24 and the lens heat plate 30, and FIG. 2C is an enlarged view of a contact portion between the body portion 26 and the body heat plate 32. FIG. 2D is a partially enlarged view of the joined portion of the lens portion 24 and the body portion 26 after welding, and corresponds to the H portion in FIG. As shown in the figure, foam burrs are formed by welding at the joint portions 24a and 26a.

図１で説明した熱板溶着においては、樹脂を加熱して溶解させるために熱板を樹脂に接触させる。加熱後に熱板を樹脂から引き離すときに、熱板の表面に溶融した樹脂が付着して糸引きが生じることがある。この糸引きは成型品の品質に影響を与えるので、極力防止することが望ましい。そこで、従来から熱板溶着に使用する熱板の表面に、フッ素樹脂またはフッ化炭素系化合物の離型層を形成することが行われている。しかしながら、上述したように、溶着による熱と圧力によって、５０００〜１００００回程度溶着を繰り返すと、離型層が劣化してしまう。離型層が劣化した場合、溶着治具に対して再度離型処理を施す必要が生じるので、溶着治具の稼働率が低下する。特に、熱板溶着で用いられる熱板は重量が１００ｋｇ以上になることもあり、熱板の交換作業に要するコストおよび工数が大きくなる。   In the hot plate welding described with reference to FIG. 1, the hot plate is brought into contact with the resin in order to heat and melt the resin. When the hot plate is pulled away from the resin after heating, the melted resin may adhere to the surface of the hot plate and cause stringing. Since this stringing affects the quality of the molded product, it is desirable to prevent it as much as possible. Therefore, conventionally, a release layer of a fluororesin or a fluorocarbon compound has been formed on the surface of a hot plate used for hot plate welding. However, as described above, when the welding is repeated about 5000 to 10,000 times by heat and pressure due to welding, the release layer is deteriorated. When the release layer is deteriorated, it is necessary to perform a release treatment again on the welding jig, so that the operation rate of the welding jig is lowered. In particular, the hot plate used for hot plate welding may have a weight of 100 kg or more, which increases the cost and man-hour required for the hot plate replacement operation.

以下、本実施形態に係る、離型性が優れかつ耐久性の高い溶着治具の製造過程について説明する。   Hereinafter, a manufacturing process of a welding jig having excellent releasability and high durability according to the present embodiment will be described.

図３は、本実施形態に係る溶着治具２０の製造過程のフローチャートである。また、図４は、本実施形態に係る溶着治具の断面概念図である。   FIG. 3 is a flowchart of the manufacturing process of the welding jig 20 according to the present embodiment. FIG. 4 is a conceptual cross-sectional view of the welding jig according to the present embodiment.

まず、金属層１０表面に、例えば厚さ３〜１０μｍの窒化物系セラミックス薄膜１２を形成する（Ｓ１０）。この窒化物系セラミックスは、例えばビッカース硬度で１５００ＨＶ以上である、硬く耐摩耗性に優れたものを選択する。例えば、窒化物系セラミックスとして、窒化チタンアルミ、窒化クロム、窒化チタン、窒化チタンシリコン、窒化チタンアルミシリコンなどがある窒化物系セラミックス薄膜は、周知の物理気相蒸着（ＰＶＤ）法または化学気相蒸着（ＣＶＤ）法などを利用して形成することができる。   First, a nitride ceramic thin film 12 having a thickness of 3 to 10 μm, for example, is formed on the surface of the metal layer 10 (S10). As this nitride ceramic, for example, a hard and excellent wear resistance material having a Vickers hardness of 1500 HV or more is selected. For example, nitride ceramic thin films such as titanium nitride aluminum, chromium nitride, titanium nitride, titanium nitride silicon, titanium aluminum silicon nitride, etc., are known as well known physical vapor deposition (PVD) methods or chemical vapor deposition. It can be formed using a vapor deposition (CVD) method or the like.

上述したフッ化炭素系化合物は、通常、被処理部材表面の水酸基との間で脱水結合によって付着し、撥水撥油性に優れた離型層を構成する。しかし、Ｓ１０で形成された窒化物系セラミックス薄膜は窒素と金属元素とが強固に結合しているため、その表面の親水性、親和性が低く、フッ化炭素系化合物との結合が進行しにくい。そこで、本実施形態では、窒化物系セラミックス薄膜の表面を物理的または化学的に活性化させて、非活性化時よりも多くのフッ化炭素系化合物と結合する活性層１４を作り出す（Ｓ１２）。   The above-mentioned fluorocarbon compound usually adheres to the hydroxyl group on the surface of the member to be treated by dehydration bonding, and constitutes a release layer having excellent water and oil repellency. However, since the nitride-based ceramic thin film formed in S10 has a strong bond between nitrogen and the metal element, its surface has low hydrophilicity and affinity, and the bond with the fluorocarbon-based compound is unlikely to proceed. . Therefore, in this embodiment, the surface of the nitride-based ceramic thin film is physically or chemically activated to create an active layer 14 that bonds with more fluorocarbon-based compounds than when it is deactivated (S12). .

ここで、「活性層」とは、活性化処理によって処理前よりも多量の自由な結合手すなわち水酸基を表面に含むようになった層のことを言う。より具体的には、表面に付着した汚れが分解され清浄化されたり、活性化処理によって、窒化物系セラミックス薄膜表面の窒素と金属元素との結合が切断されて分子結合手ができる。この結合手に水酸基が吸着するので、窒化物系セラミックスとフッ化炭素系化合物とが結合しやすくなる。   Here, the “active layer” refers to a layer containing a larger amount of free bonds, that is, hydroxyl groups, on the surface than before the treatment by the activation treatment. More specifically, dirt adhering to the surface is decomposed and cleaned, or by activation treatment, the bond between nitrogen and the metal element on the surface of the nitride ceramic thin film is cut to form a molecular bond. Since the hydroxyl group is adsorbed on the bond, the nitride ceramic and the fluorocarbon compound are easily bonded.

このような活性層１４は、数ナノメートルから数十ナノメートルの極めて薄い層であるので、活性層１４の形成後にも窒化物系セラミックス薄膜１２が本来有している硬度および耐摩耗性を損なうことはない。   Since such an active layer 14 is an extremely thin layer of several nanometers to several tens of nanometers, the hardness and wear resistance inherent in the nitride-based ceramic thin film 12 are impaired even after the formation of the active layer 14. There is nothing.

物理的な活性化の手法として、プラズマ処理、コロナ放電処理、紫外線照射処理またはフレーム処理などがある。また、化学的な活性化の手法として、酸／アルカリ浸漬、酸化剤処理またはオゾン処理などがある。これら以外にも、窒化物系セラミックス薄膜の表面を活性化させることができれば、既知のまたは将来開発される任意の手法を選択することができる。   Examples of physical activation methods include plasma treatment, corona discharge treatment, ultraviolet irradiation treatment, and flame treatment. Chemical activation methods include acid / alkali immersion, oxidant treatment, or ozone treatment. In addition to these, any known or future developed method can be selected as long as the surface of the nitride ceramic thin film can be activated.

しかし、フレーム処理、酸／アルカリ浸漬、酸化剤処理は、窒化物系セラミックス薄膜の表面を損傷する可能性があるので、プラズマ処理、コロナ放電処理、紫外線照射処理またはオゾン処理等の、表面損傷の可能性がない活性化処理を選択することが好ましい。また、活性化の被処理材料を問わず、かつ活性化の効率が高い点で、プラズマ処理および紫外線処理を選択することがさらに好ましい。   However, flame treatment, acid / alkali soaking, and oxidant treatment may damage the surface of the nitride-based ceramic thin film, so surface damage such as plasma treatment, corona discharge treatment, ultraviolet irradiation treatment, or ozone treatment may occur. It is preferable to select an activation treatment that has no possibility. Further, it is more preferable to select the plasma treatment and the ultraviolet ray treatment regardless of the material to be activated and the high activation efficiency.

特に、活性化処理としてプラズマ処理を選択した場合は、以下のような作用が生じる。すなわち、窒化物系セラミックス薄膜の表面にプラズマを照射すると、１：表面に付着した汚れが分解され、清浄化される。２：表面の安定した窒化物の分子結合が切断され、分子結合手が不安定化（活性化）される。３：表面に水酸基などの活性（ラジカル）分子が吸着される。   In particular, when plasma processing is selected as the activation processing, the following effects occur. That is, when the surface of the nitride-based ceramic thin film is irradiated with plasma, 1: the dirt adhering to the surface is decomposed and cleaned. 2: The molecular bond of the nitride having a stable surface is broken, and the molecular bond is destabilized (activated). 3: Active (radical) molecules such as hydroxyl groups are adsorbed on the surface.

さらに図４を参照し、続いて、窒化物系セラミックス薄膜１２上にフッ化炭素系化合物を化学結合させて、離型層１６を形成する（Ｓ１４）。フッ化炭素系化合物は、フッ化炭素の鎖状部位と、他の物質と結合する反応基とから構成される。フッ化炭素系化合物の例としては、パーフルオロアルキルシラン類またはパーフルオロポリエーテル基含有シラン化合物類などがある。   Still referring to FIG. 4, subsequently, a fluorocarbon compound is chemically bonded onto the nitride ceramic thin film 12 to form a release layer 16 (S14). The fluorocarbon compound is composed of a fluorocarbon chain moiety and a reactive group that binds to another substance. Examples of fluorocarbon compounds include perfluoroalkyl silanes or perfluoropolyether group-containing silane compounds.

パーフルオロアルキルシラン類としては、ＣＦ３(ＣＦ２)ｎＣＨ２ＣＨ２Ｓｉ(ＯＭｅ)ｍ（但し、ｎ＝１，３，５，７、ｍ＝２，３、ＭｅはＣＨ３基またはＣ２Ｈ５基から選ばれる置換基）、ＣＦ３(ＣＦ２)ｎＣＨ２ＣＨ２Ｓｉ(ＯＲ)ｍ（但し、ｎ＝１，３，５，７、ｍ＝２，３、Ｒは塩素またはヨウ素等のハロゲン元素から選ばれる元素）などがある。より具体的には、ＣＦ３(ＣＦ２)５ＣＨ２ＣＨ２Ｓｉ(ＯＣＨ３)３（例えば、モメンティブ・パフォーマンス・マテリアルズ製のＴＳＬ８２５７）、ＣＦ３(ＣＦ２)７ＣＨ２ＣＨ２Ｓｉ(ＯＣＨ３)３（例えば、ＴＳＬ８２３３）、ＣＦ３(ＣＦ２)７ＣＨ２ＣＨ２Ｓｉ(ＯＣＨ３)２（例えば、ＴＳＬ８２３１または信越化学工業製のＫＢＭ７８０３）、ＣＦ３(ＣＦ２)７ＣＨ２ＣＨ２Ｓｉ(ＯＣ２Ｈ５)３（例えば、東レ・ダウコーニング製のＡＹ４３−１５８Ｅ）などがある。 Perfluoroalkylsilanes include CF 3 (CF 2 ) n CH 2 CH 2 Si (OMe) m (where n = 1, 3, 5, 7, m = 2, 3, Me is CH 3 group or C 2 H 5 substituents), CF 3 (CF 2 ) n CH 2 CH 2 Si (OR) m (where n = 1, 3, 5, 7, m = 2, 3, R is chlorine or Element selected from halogen elements such as iodine). More specifically, CF 3 (CF 2 ) 5 CH 2 CH 2 Si (OCH 3 ) 3 (for example, TSL8257 manufactured by Momentive Performance Materials), CF 3 (CF 2 ) 7 CH 2 CH 2 Si ( OCH 3 ) 3 (for example, TSL8233), CF 3 (CF 2 ) 7 CH 2 CH 2 Si (OCH 3 ) 2 (for example, TSL8231 or KBM7803 manufactured by Shin-Etsu Chemical Co., Ltd.), CF 3 (CF 2 ) 7 CH 2 CH 2 Si (OC 2 H 5 ) 3 (for example, AY43-158E manufactured by Toray Dow Corning).

パーフルオロポリエーテル基含有シラン化合物類には、パーフルオロポリエーテル変性アミノシラン（例えば、特開２０００−３２７７７２号公報を参照）、パーフルオロポリエーテル変性ポリシラザン（例えば、特開２０１０−４３２５１号公報を参照）などがある。入手可能な製品としては、信越化学工業のＫＹ−１６４、ダイキン工業のオプツールシリーズなどがある。   Examples of the perfluoropolyether group-containing silane compounds include perfluoropolyether-modified aminosilane (for example, see JP-A No. 2000-327772) and perfluoropolyether-modified polysilazane (for example, see JP-A No. 2010-43251). )and so on. Available products include KY-164 from Shin-Etsu Chemical and Optool series from Daikin Industries.

以上説明したように、本実施形態によれば、溶着治具に窒化物系セラミックス薄膜を成膜し、その表面を物理的または化学的に活性化して、従来よりも多くのフッ化炭素系化合物と結合可能となる活性層を作り出すようにした。これによると、窒化物系セラミックス薄膜の硬度および耐摩耗性のために、溶着治具使用時の摩耗による表面損耗量を低減することができるので、フッ化炭素系化合物による撥水撥油性を長期間維持することが可能になる。   As described above, according to the present embodiment, a nitride ceramic thin film is formed on the welding jig, and the surface thereof is physically or chemically activated to increase the number of fluorocarbon compounds compared to the prior art. An active layer that can be combined with is created. According to this, because of the hardness and wear resistance of the nitride ceramic thin film, the amount of surface wear due to wear when using the welding jig can be reduced, so the water and oil repellency of the fluorocarbon compound is increased. It becomes possible to maintain the period.

本実施形態にしたがって作成された溶着治具は、従来の離型処理が施された溶着治具と同等の離型性を有することが確認された。また、熱板溶着を繰り返し行っても、物理的な損傷を受けないことも確認された。さらに、従来の離型処理で使用されていたフッ素樹脂のように熱により軟化することがないので、フッ素樹脂では使用できない２５０°Ｃ以上の高温下でも使用することが可能である。このような特性によって、本実施形態にしたがって作成された溶着治具は、溶着治具の使用可能期間が大きく増加するので、溶着治具の交換回数を減らし、これに要する工数も削減することができる。   It was confirmed that the welding jig created according to the present embodiment has a mold release property equivalent to that of the welding jig subjected to the conventional mold release treatment. It was also confirmed that physical damage was not caused even by repeated hot plate welding. Further, since it is not softened by heat unlike the fluororesin used in the conventional mold release treatment, it can be used even at a high temperature of 250 ° C. or higher, which cannot be used with a fluororesin. Due to such characteristics, the welding jig created according to the present embodiment greatly increases the usable period of the welding jig, so that the number of times of replacement of the welding jig can be reduced and the man-hour required for this can be reduced. it can.

炭素鋼（Ｓ５０Ｃ）製の熱板溶着用の治具を作成し、治具の表面を研磨した後、最終的に＃８００の研磨布を用いて研磨を行った。有機溶媒中に治具を入れて超音波洗浄を１分間行い、治具表面の油分や金属粉を取り除いた。続いて、真空成膜装置内に治具を納めて、表面に窒化物系セラミックス薄膜を形成した。真空成膜装置は、日新電機（株）製マルチアークＰＶＤを使用した。成膜手順は、まず表面清浄化のためにアルゴンイオンによるボンバード処理を行い、その後、窒化チタンアルミ（ＴｉＡｌＮ）を５μｍ厚で成膜した。ＴｉとＡｌの比率は５０：５０である。 Example A jig for hot plate welding made of carbon steel (S50C) was prepared, and the surface of the jig was polished, and finally polished using a # 800 polishing cloth. The jig was placed in an organic solvent and subjected to ultrasonic cleaning for 1 minute to remove oil and metal powder on the jig surface. Subsequently, a jig was placed in the vacuum film forming apparatus to form a nitride ceramic thin film on the surface. A multi-arc PVD manufactured by Nissin Electric Co., Ltd. was used as the vacuum film forming apparatus. In the film formation procedure, first, bombarding with argon ions was performed to clean the surface, and then titanium nitride aluminum (TiAlN) was formed to a thickness of 5 μm. The ratio of Ti and Al is 50:50.

成膜終了後、取り出した治具を再び洗浄して表面残渣を取り除いた。続いて、プラズマトリート社製大気圧プラズマ装置を利用して、活性化処理を行った。プラズマ電源出力が１ｋＶＡ、プラズマ噴出ノズルと治具との間隔は１５ｍｍ、走査速度２０ｍｍ／ｓ、繰り返し回数５回の条件でプラズマ処理を行った。このプラズマ処理によって、治具表面は活性化すなわち親水化される。具体的には、プラズマ処理前は水の接触角が約７０°であったのに対し、プラズマ処理後は２０°以下となる。   After the film formation was completed, the removed jig was washed again to remove surface residues. Subsequently, activation treatment was performed using an atmospheric pressure plasma apparatus manufactured by Plasmatreat. Plasma treatment was performed under the conditions of a plasma power output of 1 kVA, a distance between the plasma ejection nozzle and the jig of 15 mm, a scanning speed of 20 mm / s, and a repetition count of 5 times. By this plasma treatment, the jig surface is activated, that is, made hydrophilic. Specifically, the contact angle of water was about 70 ° before the plasma treatment, but 20 ° or less after the plasma treatment.

治具のプラズマ処理後、直ちにフッ化炭素系化合物からなる離型剤を塗布し、その後治具を乾燥させた。フッ化炭素系化合物の離型剤には、信越化学工業（株）のＫＹ−１６４を使用した。治具表面と離型剤との反応促進のため、乾燥後約２００°Ｃで加熱した。離型処理後の治具は、水の接触角が約１２０°に向上した。   Immediately after plasma treatment of the jig, a release agent comprising a fluorocarbon compound was applied, and then the jig was dried. KY-164 of Shin-Etsu Chemical Co., Ltd. was used as the mold release agent for the fluorocarbon compound. In order to accelerate the reaction between the jig surface and the release agent, it was heated at about 200 ° C. after drying. The jig after the mold release treatment improved the water contact angle to about 120 °.

上記のようにして作成された熱板溶着用の治具を使用して、樹脂部品の熱板溶着試験を約４０００回行ったが、樹脂部品および熱板溶着治具の糸引きは生じず、また治具表面の損傷も確認することはできなかった。   Using the hot plate welding jig created as described above, the hot plate welding test of the resin component was performed about 4000 times, but the stringing of the resin component and the hot plate welding jig did not occur, In addition, damage to the jig surface could not be confirmed.

離型処理剤として信越化学工業のＫＹ−１６４またはダイキン工業のオプツールＨＤ−２１００Ｚ、窒化物系セラミックスとして窒化チタンアルミまたは窒化クロムをそれぞれ使用する全ての組み合わせについて、上記と同様の熱板溶着試験を行った。いずれの組み合わせについても、樹脂部品および熱板溶着治具の糸引きが生じず、また治具表面の損傷も発生しないことが確認された。   For all combinations using KY-164 from Shin-Etsu Chemical Co., Ltd. as the mold release treatment agent or Optool HD-2100Z from Daikin Industries, and titanium aluminum nitride or chromium nitride as the nitride ceramics, the same hot plate welding test as above was performed. went. In any combination, it was confirmed that stringing of the resin component and the hot plate welding jig did not occur, and damage to the jig surface did not occur.
