Description
本発明は、独立請求項の上位概念に記載されているとおりの減摩塗料、減摩塗料をベースとする被覆を有する、ウインドウワイパーのワイパーブレード、ならびにワイパーブレードを製造する方法に関する。 The present invention relates to an antifriction coating as described in the superordinate concept of the independent claim, a wiper blade of a window wiper having a coating based on the antifriction coating, and a method of manufacturing the wiper blade.
従来技術
ウインドウワイパーのワイパーブレードは一般に、エラストマーからなる異形材を基に製造されており、このことによってワイパーブレードと、払拭されるガラス表面との間の最適な接触が、その表面の輪郭とは無関係に保証されている。このために、ワイパーブレードはワイパーゴム異形材を備えており、これはたとえば天然ゴム、クロロプレン、シリコーンゴムまたはポリウレタンゴムを基に製造されている。しかしゴム材料は、払拭されるガラス表面と接触する際に高い摩擦係数を示すので、ガラス表面の汚れを払拭するために必要とされる水平移動のためには高いエネルギーが消費される。さらにこの場合に大きな作動音がする。
PRIOR ART Window wiper wiper blades are generally manufactured on the basis of an elastomeric profile, so that the optimum contact between the wiper blade and the surface of the glass to be wiped is the contour of the surface. Guaranteed regardless. For this purpose, the wiper blade is provided with a wiper rubber profile, which is produced, for example, on the basis of natural rubber, chloroprene, silicone rubber or polyurethane rubber. However, since the rubber material exhibits a high coefficient of friction when in contact with the glass surface being wiped, high energy is consumed for the horizontal movement required to wipe away the dirt on the glass surface. Furthermore, there is a loud operating noise in this case.
ワイパー用異形材の摩擦係数を低減するために、たとえばＵＳ６，７３０，３６０からは、エラストマー異形材のための表面被覆の使用が公知であり、これは、ポリウレタンとシロキサン以外に、ポリアミド粉末、ポリエチレン粉末またはポリアミド溶液を含有する減摩塗料を施与することによって行われる。減摩塗料中に含有されているこれらの潤滑剤は、硬質粒子のタイプに分類され、構成上は被覆から突出し、このことによってワイパーゴムと汚れを払拭されるガラス表面との間のスペーサーとして作用する。このことはワイパー品質の低減という否定的な効果と結びついており、これはたとえば縞模様の形成において現れる。さらに該粒子は被覆マトリックスへの付着性が低いため、ワイパーゴムの使用の間に表面から容易にはく離しうる。 In order to reduce the coefficient of friction of the profile for wipers, for example from US Pat. No. 6,730,360, the use of surface coatings for elastomer profiles is known, which includes, in addition to polyurethane and siloxane, polyamide powder, polyethylene This is done by applying an antifriction coating containing a powder or polyamide solution. These lubricants contained in anti-friction coatings are classified as hard particle types and project structurally from the coating, thereby acting as a spacer between the wiper rubber and the glass surface being wiped away. To do. This is associated with a negative effect of reducing wiper quality, which appears for example in the formation of stripes. In addition, the particles have a low adhesion to the coating matrix and can be easily detached from the surface during use of the wiper rubber.
発明の開示
本発明の課題は、ゴム材料を被覆するための減摩塗料ならびに該減摩塗料を含むワイパーブレードを製造する方法を提供することであり、このことによって、低い摩擦値と同時に良好な拭き跡(Wischbild)を示すワイパーブレードのためのワイパーゴムの製造が可能になる。
DISCLOSURE OF THE INVENTION It is an object of the present invention to provide an antifriction coating for coating rubber materials and a method of manufacturing a wiper blade containing the antifriction coating, which provides good performance at the same time as low friction values. It is possible to produce wiper rubber for wiper blades that show wiping marks (Wischbild).
本発明の根底に存在する課題は、独立請求項の特徴を有するゴム材料、減摩塗料をベースとする表面被覆を含むウインドウワイパーのワイパーブレードを被覆するための減摩塗料によって、ならびにその製造方法によって解決される。 The problem underlying the present invention is that of a rubber material having the features of the independent claim, an antifriction coating for coating a wiper blade of a window wiper including a surface coating based on the antifriction coating, and a method for its manufacture Solved by.
本発明による減摩塗料によってワイパーゴム異形材の被覆が可能になり、該異形材は極めて耐摩耗性であり、実質的にクリアな拭き跡を示す。このようにして作られた被覆は、軟質の粒子から形成される充填剤成分、たとえばグラファイトを潤滑剤として、ならびに適切に硬化する結合剤成分を含有する複合材構造を形成している。比較的軟質の潤滑剤粒子は、得られるワイパーゴムの高いワイピング品質(Wischqualitaet)をもたらし、かつ使用される硬質の結合剤成分は、ワイパーゴムの表面上での潤滑剤粒子の強固な結合を、低い摩擦係数および高い耐摩耗性という肯定的な副作用と共にもたらす。 The antifriction coating according to the present invention allows for the coating of a wiper rubber profile, which is extremely wear resistant and exhibits a substantially clear wipe. The coating produced in this way forms a composite structure containing a filler component formed from soft particles, for example graphite as a lubricant, and a binder component that cures appropriately. The relatively soft lubricant particles provide the high wipe quality of the resulting wiper rubber (Wischqualitaet), and the hard binder component used provides a strong bond of the lubricant particles on the surface of the wiper rubber, With positive side effects of low coefficient of friction and high wear resistance.
さらに本発明によるワイパーブレードは、自動車の疎水性フロントガラスの汚れを払拭するためにも適切である。その撥水効果に基づいて、水分が作用する際に潤滑剤のような働きをする水の膜はその表面上に形成されない。その限りでワイパーブレードは、このような疎水性ガラス表面をワイピングする際に、乾燥した表面上における場合に匹敵する特性を示す。このため、疎水性のフロントガラスの汚れを払拭する場合には、優れた潤滑特性が、高い耐摩耗性と満足のゆく拭き跡と共に可能となる被覆が前提となっている。このようなワイパーゴムの被覆をグラファイトまたは二硫化モリブデンをベースとして製造する場合には、これらは、払拭されるガラス表面上でのワイパーブレードの摩擦係数の低下につながる。 Furthermore, the wiper blade according to the invention is also suitable for wiping off the dirt on the hydrophobic windshield of automobiles. Based on the water repellent effect, a water film that acts like a lubricant when moisture acts is not formed on the surface. As such, wiper blades exhibit properties comparable to those on dry surfaces when wiping such hydrophobic glass surfaces. For this reason, in the case of wiping off dirt on the hydrophobic windshield, it is premised on a coating that enables excellent lubrication characteristics together with high wear resistance and a satisfactory wiping trace. When such wiper rubber coatings are manufactured on the basis of graphite or molybdenum disulfide, these lead to a reduction in the coefficient of friction of the wiper blade on the glass surface to be wiped.
ただし潤滑剤としてのグラファイトの効率は、ワイパーゴムの表面被覆中でのその濃度に著しく依存する。そのため、グラファイト粒子は、その柔らかさ、および表面被覆中で通常必要とされる高い濃度、ひいては表面被覆へのその結合性の低さに基づいて、すぐに侵食される傾向があり、このことによってワイパーゴム異形材の耐摩耗性が低下する。十分に低い摩擦係数を達成するために、グラファイトはしばしば、被覆中での臨界的な顔料体積濃度を超えて添加され、このため、被覆への潤滑剤の結合性が低いことに基づいて高い摩耗につながる。 However, the efficiency of graphite as a lubricant depends significantly on its concentration in the wiper rubber surface coating. As such, graphite particles tend to erode quickly, based on their softness and the high concentration normally required in surface coatings, and hence their low binding to surface coatings. The wear resistance of the wiper rubber profile is reduced. In order to achieve a sufficiently low coefficient of friction, graphite is often added beyond the critical pigment volume concentration in the coating, which results in high wear based on low lubricant binding to the coating. Leads to.
本発明のその他の有利な実施態様は、従属請求項から明らかである。 Other advantageous embodiments of the invention are evident from the dependent claims.
たとえば、減摩塗料の樹脂成分として、ヒドロキシル基変性されたポリエステルおよび／またはポリアクリレートを使用することが有利である。樹脂成分を硬化させるためにメラミン−ホルムアルデヒド架橋剤および／またはイソシアネート架橋剤を使用する場合、充填剤成分としてのグラファイトと共にポリマーマトリックスが生じ、これはグラファイトの高い体積画分にもかかわらず、潤滑剤粒子として機能する充填剤成分の、被覆マトリックスへの十分な結合を可能にするためには十分の硬度を有する。 For example, it is advantageous to use a hydroxyl-modified polyester and / or polyacrylate as the resin component of the antifriction coating. When melamine-formaldehyde crosslinkers and / or isocyanate crosslinkers are used to cure the resin component, a polymer matrix is produced with graphite as a filler component, which is a lubricant despite the high volume fraction of graphite. It has sufficient hardness to allow sufficient bonding of the filler component functioning as particles to the coating matrix.
本発明の特に有利な実施態様によれば、前記の被覆されたゴム材料を含むワイパーブレードの製造は、まず、ワイパーゴムを二重異形材(Doppelprofil)の形で製造し、かつ減摩塗料で被覆することによって行う。引き続きまず、ワイパーゴム異形材を個別の部材に分割し、かつ最後に減摩塗料の架橋を行う。このようにして、切断端部によって境界付けられ、後に払拭されるガラス板に対向する範囲を形成する切断面の範囲では減摩塗料によって被覆されていないワイパーゴム異形材が得られる。 According to a particularly advantageous embodiment of the invention, the manufacture of the wiper blade comprising the coated rubber material is first made in the form of a double profile (Doppelprofil) and with an antifriction coating. This is done by coating. Subsequently, the wiper rubber profile is first divided into individual parts and finally the antifriction coating is crosslinked. In this way, a wiper rubber profile is obtained which is not covered by the antifriction coating in the area of the cut surface which is bounded by the cut edge and forms the area facing the glass plate to be wiped later.
該ワイパーゴム異形材は運転中に、ワイパー運動に基づいて、減摩塗料により被覆されている切断端部によりガラス面上をスライドする傾向があるが、ワイパー運動の転向点において全面においてその被覆されていない切断面によってガラス板上に存在し、ワイパーゴム異形材が対向運動する際に、減摩塗料によって被覆された切断端部とガラス板とが接触する。 The wiper rubber profile tends to slide on the glass surface during operation due to the wiper motion, but on the entire surface at the turning point of the wiper motion. When the wiper rubber profile is opposed to the glass plate, the cut end covered with the antifriction coating comes into contact with the glass plate.
これは有利なことである。というのも、ワイパー運動の間には単にワイパーゴム異形材の、減摩塗料によって被覆された区分のみが、払拭されるガラス板と接触し、その際、ワイパーゴム異形材は、低い摩擦係数と、良好な拭き跡を示すからである。転向点では、ワイパーゴム異形材はその被覆されていない切断面で、クリーニングすべきガラス板と接触し、その際、被覆されていないゴム材料の高い摩擦係数に基づいて、顕著な音を生じることなく迅速な反転プロセスにつながり、ワイパーゴム異形材の迅速な、対向するワイパー運動がもたらされる。 This is advantageous. This is because during the wiper movement, only the section of the wiper rubber profile, which is coated with anti-friction paint, contacts the glass plate to be wiped, and the wiper rubber profile has a low coefficient of friction. This is because good wiping marks are exhibited. At the turning point, the wiper rubber profile comes into contact with the glass plate to be cleaned at its uncoated cut surface, and produces a pronounced sound based on the high coefficient of friction of the uncoated rubber material. Leading to a quick reversal process, resulting in a quick and opposing wiper movement of the wiper rubber profile.
実施例
本発明は、ゴム材料、たとえば自動車のウインドウワイパーのためのワイパーブレードのワイパーゴムを被覆するための減摩塗料に関する。このようなワイパーゴムは、ゴム成分としてたとえば天然ゴム（ＮＲ）、ポリクロロプレン（ＣＲ）、ＥＰＤＭ、ポリイソプレン（ＩＲ）、ポリブタジエン（ＢＲ）、ポリスチレンブタジエン（ＳＢＲ）、ポリアクリロニトリルブタジエン（ＮＢＲ）、ポリアクリロニトリルブタジエンとＰＶＣとの混合物、または前記のゴム材料相互の混合物を含有しているゴム材料からなるマトリックスを含む。

It includes a matrix made of a rubber material containing a mixture of acrylonitrile butadiene and PVC, or a mixture of the above rubber materials.
このようなワイパーゴムの物理的特性、たとえば摩擦係数および耐摩耗性を改善するために、ゴム材料は、充填剤成分Ｂとしての軟質の乾燥潤滑剤と、硬化した状態で比較的硬質な結合剤成分Ａを含有する減摩塗料によって被覆される。充填剤成分Ｂとして、たとえばグラファイトが使用される。これは減摩塗料中に３〜２０質量％、有利には５〜１５質量％の割合で、特に減摩塗料中に７〜１０質量％含有されている。 In order to improve the physical properties of such wiper rubber, such as the coefficient of friction and the wear resistance, the rubber material comprises a soft dry lubricant as filler component B and a relatively hard binder in the cured state. Coated with anti-friction paint containing component A. As the filler component B, for example, graphite is used. This is contained in the antifriction coating in a proportion of 3 to 20% by weight, preferably 5 to 15% by weight, in particular 7 to 10% by weight in the antifriction coating.
さらに減摩塗料は、たとえばポリアクリレートおよび／またはポリエステルにより形成されているか、またはこれらを含有する樹脂成分Ａを含有する。有利には樹脂成分Ａとして、ヒドロキシル基変性ポリマーを使用する。ヒドロキシル基による変性度は、たとえば０．５〜２０質量％、有利には１〜１５質量％、特に２〜１０質量％であり、その際、百分率の記載はそのつどポリマー１００ｇあたりのヒドロキシ官能基の量に対するものである。 Furthermore, the antifriction coating is formed of, for example, polyacrylate and / or polyester, or contains a resin component A containing these. A hydroxyl group-modified polymer is preferably used as the resin component A. The degree of modification with hydroxyl groups is, for example, 0.5 to 20% by weight, preferably 1 to 15% by weight, in particular 2 to 10% by weight, the percentages being stated each time the hydroxy functional groups per 100 g of polymer. It is for the amount of.
硬化した減摩塗料中の結合剤成分Ａの割合は、たとえば１〜３０質量％、有利には１．５〜２０質量％、特に１．７〜９質量％である。 The proportion of binder component A in the cured antifriction coating is, for example, 1-30% by weight, preferably 1.5-20% by weight, in particular 1.7-9% by weight.
結合剤成分Ａを硬化するために、減摩塗料にはさらに、たとえば硬化剤成分Ｃを添加する。硬化剤成分Ｃはたとえばイソシアネートまたはメラミン／ホルムアルデヒド樹脂をベースとする硬化剤であってよい。その際に、硬化剤成分Ｃの割合は、硬化した減摩塗料中で、たとえば０．２〜２０質量％、有利には０．５〜１５質量％、特に１．５〜９質量％である。 In order to cure the binder component A, for example, a curing agent component C is added to the antifriction coating. Curing agent component C can be, for example, a curing agent based on isocyanate or melamine / formaldehyde resin. In that case, the proportion of the hardener component C is, for example, 0.2 to 20% by weight, preferably 0.5 to 15% by weight, in particular 1.5 to 9% by weight, in the hardened antifriction coating. .
減摩塗料の硬化後に、得られたゴム材料の被覆中の結合剤成分Ａの割合は、たとえば５〜５０質量％、有利には１０〜４５質量％および特に２０〜４５質量％であり、充填剤成分Ｂの割合は、たとえば３０〜８０質量％、有利には３５〜７０質量％、および特に３５〜６５質量％であり、かつ硬化剤成分Ｃの割合は、たとえば０．５〜４５質量％、有利には４〜４０質量％および特に７〜３８質量％である。 After curing of the antifriction coating, the proportion of binder component A in the coating of the rubber material obtained is, for example, 5 to 50% by weight, preferably 10 to 45% by weight and in particular 20 to 45% by weight. The proportion of agent component B is, for example, 30 to 80% by weight, preferably 35 to 70% by weight, and in particular 35 to 65% by weight, and the proportion of curing agent component C is, for example, 0.5 to 45% by weight. , Preferably 4 to 40% by weight and in particular 7 to 38% by weight.
ウインドウワイパーのワイパーブレードのためのワイパーゴム異形材の製造は、まずワイパーゴム異形材を二重ストランド(Doppelstrang)の形で押出成形するか、射出成形によって製造することによって行う。減摩塗料で被覆する前に、場合により異形材表面のハロゲン化、特に塩素化を実施することができる。これは、ゴム表面の付加的な硬化もしくは化学的な変性を行うことができ、このことにより減摩塗料の塗布により形成された被覆の付着性を改善することができるという利点を有する。その後、二重異形材を、前記の減摩塗料で被覆し、かつ引き続き二重ストランドを長さ方向に２つの個々の異形材ストランドに分割し、これらをふたたび個々のワイパーゴム異形材を製造するために分割することができる。最後に減摩塗料の架橋を行う。 The wiper rubber profile for the wiper blade of the window wiper is produced by first extruding the wiper rubber profile in the form of a double strand (Doppelstrang) or by injection molding. Before coating with the antifriction coating, it is possible to carry out halogenation, in particular chlorination, on the profile surface. This has the advantage that additional curing or chemical modification of the rubber surface can be performed, which can improve the adhesion of the coating formed by application of the anti-friction paint. The double profile is then coated with the anti-friction paint and the double strand is subsequently divided into two individual profile strands in the longitudinal direction, which are again produced into individual wiper rubber profiles. Can be divided for. Finally, the antifriction coating is crosslinked.

このようにして、４５．７：５４．３の結合剤Ａおよび硬化剤Ｃの割合の合計に対する充填剤割合の比率が生じ、このことによりワイパーゴムの良好な減摩特性が得られる。被覆へのグラファイト粒子の強力な結合によって、優れた耐摩耗性が生じる。 In this way, a ratio of filler proportion to the sum of the proportions of binder A and curing agent C of 45.7: 54.3 is produced, which gives good antifriction properties of the wiper rubber. Excellent wear resistance results from the strong bonding of the graphite particles to the coating.
例１に記載の減摩塗料により被覆したゴム材料の摩擦係数を測定するために、親水性のガラス表面上および疎水性のガラス表面上で測定を実施する。たとえば濡れた親水性ガラス表面上での摩擦係数は、３０ｃｍ／ｓｅｃのワイパー速度の場合、測定の開始時には０．４８であり、かつ１時間のワイパー運動の後では０．４０である。濡れた疎水性ガラス表面上では、３０ｃｍ／ｓｅｃのワイパー速度の場合、ワイパー運動の開始時には０．３７であり、かつ１時間後には０．３５である。特に負荷のかかるワイパーリップの外側のコーナー部を顕微鏡で観察したところ、機械的な損傷は生じていないことが判明した。拭き跡はクリアである。 In order to determine the coefficient of friction of the rubber material coated with the antifriction paint described in Example 1, measurements are carried out on hydrophilic glass surfaces and hydrophobic glass surfaces. For example, the coefficient of friction on a wet hydrophilic glass surface is 0.48 at the start of the measurement for a wiper speed of 30 cm / sec and 0.40 after 1 hour of wiper movement. On the wet hydrophobic glass surface, for a wiper speed of 30 cm / sec, it is 0.37 at the start of the wiper movement and 0.35 after 1 hour. When the outer corner of the wiper lip, which was particularly loaded, was observed with a microscope, it was found that no mechanical damage occurred. The wipe is clear.
例２

結合剤成分Ａ ４１．２質量％、
充填剤成分Ｂ ４５．８質量％、
硬化剤成分Ｃ １３．０質量％。
Example 2

The production of wiper rubber coated with anti-friction paint is carried out as described in Example 1. The resulting coating having a film thickness of about 4 μm has the following composition:
41.2% by weight of binder component A,
45.8% by weight of filler component B,
Hardener component C 13.0% by mass.
従って、結合剤Ａおよび硬化剤Ｃの割合の合計に対する充填剤割合の比率が、５４．２／４５．８の被覆が得られる。例１と同様の比較可能な物理的特性が、クリアな拭き跡と共に生じる。 Thus, a coating with a filler ratio of 54.2 / 45.8 relative to the sum of binder A and curing agent C is obtained. Similar physical properties as in Example 1 occur with a clear wipe.

結合剤成分Ａ ３４．３質量％、
充填剤成分Ｂ ５１．７質量％、
硬化剤成分Ｃ １４．０質量％。

Binder component A 34.3% by weight,
51.7% by weight of filler component B,
