Description
本発明は、軋み音防止表面処理剤に係り、更に詳細には、インストルメントパネル、ドアトリム、ピラー等の自動車の内装部品に好適に用いられ、自動車の走行時の振動により内装部品が擦れあって発生する軋み音を低減ないし防止する軋み音防止表面処理剤に関する。 The present invention relates to a squeaking noise-preventing surface treatment agent, and more particularly, is suitably used for automobile interior parts such as instrument panels, door trims, pillars, and the like, and the interior parts are rubbed by vibrations during automobile travel. The present invention relates to a stagnation-sound-preventing surface treatment agent that reduces or prevents the squeaking sound that occurs.
従来から、インストルメントパネル、ドアトリム、ピラー、コンソール、メータークラスターなどの内装部品は主にポリプロピレン(PP)などのオレフィン系樹脂やアクリロニトリルブタジエンスチレン(ABS)樹脂などを射出成形により成形しており、その表層は塩化ビニル(PVC)シートや熱可塑性オレフィン(TPO)シートで覆われているものが知られている。
また、その表層には耐光性を付与したり低光沢化などを付与する目的で厚さ10〜30μmのアクリル−塩化ビニル系塗料やウレタン系塗料等を塗布する表面処理が施されているものも知られている。
これらの自動車内装部品同士が隣接する部分では、隣接する部品間の隙間が大きいと、見栄えが悪く高級感に欠けることからできるだけ隙間を小さくしている。
また、これらの自動車内装部品同士が相互に接触する部分では、自動車走行時の振動、開閉動作、乗車又は降車動作などにより内装部品同士が擦れあい軋み音が発生する。
Traditionally, interior parts such as instrument panels, door trims, pillars, consoles, and meter clusters have been mainly molded by injection molding of olefin resins such as polypropylene (PP) and acrylonitrile butadiene styrene (ABS) resins. The surface layer is known to be covered with a vinyl chloride (PVC) sheet or a thermoplastic olefin (TPO) sheet.
Also, the surface layer may be subjected to a surface treatment to apply an acrylic-vinyl chloride paint or urethane paint having a thickness of 10 to 30 μm for the purpose of imparting light resistance or low gloss. Are known.
In the part where these automobile interior parts are adjacent to each other, if the gap between the adjacent parts is large, the appearance is not good and lacks a high-class feeling, so the gap is made as small as possible.
In addition, at the part where these automobile interior parts are in contact with each other, the interior parts are rubbed together due to vibration, opening / closing operation, getting-on or getting-off operation, etc. when the automobile is running, and a squeak noise is generated.
一方で、ウレタン樹脂中にウレタンの微粒子を含有させた表面処理剤が提案されている(例えば、特許文献1参照。)。
また、アクリル−塩化ビニル系塗料用樹脂にウレタンの微粒子を含有させた表面処理剤が提案されている(例えば、特許文献2〜4参照。)。
Further, a surface treatment agent in which urethane fine particles are contained in an acrylic-vinyl chloride paint resin has been proposed (see, for example, Patent Documents 2 to 4).
しかしながら、従来のウレタン系塗料にウレタンの微粒子を含有させた表面処理剤は、アクリル系塗料に比べてコストが高く、更に接触している部品が滑り出す時に発生する単発音に対しては、アクリル系塗料に比べて劣るという問題点があった。
また、ウレタン系塗料では表層の着色塗料の摩擦や摩耗による色落ち性や色移り性が劣るという問題点があった。
更に、アクリル−塩化ビニル系塗料塗料用樹脂にウレタンの微粒子を含有させた表面処理剤は、接触する部品間の荷重が高くなった場合の耐久性が不十分であり改善の余地があった。
However, surface treatment agents containing urethane fine particles in conventional urethane paints are more expensive than acrylic paints, and acrylics are used for single sounds that occur when the parts in contact slide out. There was a problem that it was inferior to the paint.
In addition, urethane-based paints have a problem that color fading and color transfer due to friction and abrasion of colored paints on the surface layer are inferior.
Furthermore, the surface treatment agent in which urethane fine particles are contained in an acrylic-vinyl chloride paint resin is insufficient in durability when the load between contacting parts becomes high, and there is room for improvement.
本発明は、このような従来技術の有する課題に鑑みてなされたものであり、その目的とするところは、自動車の内装部品の接触部から発生する軋み音を低減ないし防止し、更に荷重依存性に優れ、耐久性を向上させた軋み音防止表面処理剤を提供することにある。 The present invention has been made in view of such problems of the prior art. The object of the present invention is to reduce or prevent the squeaking noise generated from the contact portion of the interior parts of an automobile, and to further depend on the load dependency. An object of the present invention is to provide an anti-smacking surface treatment agent having excellent durability and improved durability.
本発明者は、上記目的を達成すべく鋭意研究を重ねた結果、表面処理剤に所定のセラミック粒子を含有させることなどにより、上記目的を達成できることを見出し、本発明を完成するに至った。
即ち、本発明の軋み音防止表面処理剤は、自動車の内装部品に用いられる表面処理剤に、平均粒径5〜200nmの球状セラミック粒子を含有させて成る。
As a result of intensive studies to achieve the above object, the present inventor has found that the above object can be achieved by including predetermined ceramic particles in the surface treatment agent, and has completed the present invention.
That is, the squeaking noise preventing surface treatment agent of the present invention is obtained by adding spherical ceramic particles having an average particle size of 5 to 200 nm to a surface treatment agent used for automobile interior parts.
本発明によれば、自動車の内装部品に用いられる表面処理剤に、平均粒径5〜200nmの球状セラミック粒子を添加することなどとしたため、自動車の内装部品の接触部から発生する軋み音を低減ないし防止し、更に荷重依存性に優れ、耐久性を向上させた軋み音防止表面処理剤を提供することができる。 According to the present invention, spherical ceramic particles having an average particle size of 5 to 200 nm are added to the surface treatment agent used for automobile interior parts, so that the squeaking noise generated from the contact portion of the automobile interior parts is reduced. Further, it is possible to provide a stagnation-preventing surface treatment agent that is excellent in load dependency and improved in durability.
以下、本発明の軋み音防止表面処理剤について詳細に説明する。本明細書において、「%」は特記しない限り、質量百分率を表すものとする。
上述の如く、本発明の軋み音防止表面処理剤は、自動車の内装部品に用いられる表面処理剤に、平均粒径5〜200nmの球状セラミック粒子を含有させたものである。
ここで、表面処理剤としては、従来公知のものを用いることができ、例えばアクリル−塩化ビニル系塗料樹脂、ウレタン樹脂などのコーティング剤やフッ素系ディスパージョンなどを挙げることができる。
また、本発明に使用できるセラミック粒子としては、例えば酸化チタン、二酸化チタン、酸化亜鉛、酸化ケイ素、タルク、ウィレムサイト、ケロライト、ピメライト、パイロフィライト、フェリパイロフィライト、クレー、酸化アルミニウム、酸化鉄、カーボンブラック、フッ素マイカ、マイカ、ベンナイト、カリオナイト、ディカイト、ナクライト、オーディナイト、モンモリロナイト、リザーダイト、アメサイト、ネポーアイト、フレポナイト、ブリンドリアイトなどを挙げることができ、これらを混合して用いてもよい。
Hereinafter, the squeaking noise preventing surface treatment agent of the present invention will be described in detail. In the present specification, “%” represents a mass percentage unless otherwise specified.
As described above, the squeaking noise preventing surface treatment agent of the present invention is obtained by adding spherical ceramic particles having an average particle diameter of 5 to 200 nm to a surface treatment agent used for automobile interior parts.
Here, as the surface treatment agent, conventionally known ones can be used, and examples thereof include coating agents such as acrylic-vinyl chloride paint resins and urethane resins, and fluorine dispersions.
Examples of the ceramic particles that can be used in the present invention include titanium oxide, titanium dioxide, zinc oxide, silicon oxide, talc, willemsite, kerolite, pimelite, pyrophyllite, ferripyrophyllite, clay, aluminum oxide, iron oxide. , Carbon black, fluorine mica, mica, bennite, carionite, dickite, nacrite, audinite, montmorillonite, lizardite, amesite, nepoite, fleponite, blindriaite, etc. may be used as a mixture .
このような表面処理剤に平均粒径が5〜200nmの球状セラミック粒子を含有させて得られたものを自動車の内装部品に用いると軋み音を低減ないし防止することができる。 It is possible to reduce or prevent squeaking noise by using such a surface treatment agent containing spherical ceramic particles having an average particle size of 5 to 200 nm for interior parts of automobiles.
ここで、現時点で推定される本発明の軋み音防止表面処理剤が部品間に発生する軋み音を低減させるメカニズムについて説明する。
自動車室内において発生する音は2種類に大別できる。一方は部品が滑り出す時に発生する単発音であり、他方は自動車走行時の定常的な振動によって発生する連続音である。単発音は発進時や段差乗り越え時などに内装部品が衝撃を受けた時に発生するものであり、連続音は路面の状況によって車両が走行中、連続的に頻繁に起こり得るものである。 本発明は、これら双方を低減すること目的とするものである。
Here, a mechanism for reducing the squeaking noise generated between the parts by the stagnation-preventing surface treatment agent of the present invention estimated at present will be described.
There are two types of sounds generated in the car interior. One is a single sound that is generated when a part starts to slide, and the other is a continuous sound that is generated by steady vibration during driving of the automobile. A single sound is generated when an interior part receives an impact when starting or overcoming a step, and a continuous sound can occur continuously and frequently while the vehicle is traveling depending on the road surface condition. The present invention aims to reduce both of these.
図1に、試験例で用いた往復動による評価試験の概要を示す。同図に示すように、被試験体1と被試験体2を用い、必要に応じて被試験体2に矢印A方向に荷重をかけて、被試験体1を矢印B方向に往復動させる。
このときに被試験体1上で被試験体2を滑らせる試験を行い、2つの被試験体間の摩擦係数の経時変化を測定すると、一般的に、図2に示すような時間に対する摩擦係数の変化したデータが得られる。
単発音に対しては、静摩擦係数と動摩擦係数との差を小さくすることが有効であり、連続的な微振動によって発生する音を防止するためには動摩擦係数の変動幅を小さくすることが有効である。
FIG. 1 shows an outline of the evaluation test by reciprocation used in the test example. As shown in the figure, a device under test 1 and a device under test 2 are used, a load is applied to the device under test 2 in the direction of arrow A as required, and the device under test 1 is reciprocated in the direction of arrow B.
At this time, when a test of sliding the DUT 2 on the DUT 1 is performed and the change over time in the coefficient of friction between the two DUTs is measured, generally the friction coefficient with respect to time as shown in FIG. Can be obtained.
For single sounds, it is effective to reduce the difference between the coefficient of static friction and the coefficient of dynamic friction, and it is effective to reduce the fluctuation range of the coefficient of dynamic friction to prevent the sound generated by continuous microvibration. It is.
また、現時点で推定される本発明の軋み音防止表面処理剤が、部品の摩耗を抑制するメカニズムについて説明する。
表面処理剤に添加された粒子は接触部にコロ状態を形成し、粒子が転がることにより、摺動時の応力を低下させ、部品の摩耗を抑制していると考えられ、結果として部品の耐久性を向上させることができる。
セラミック粒子は、従来の樹脂粒子と比較して硬度が高いため、接触する2物品間の接触面圧が高い場合でも、粒子がほとんど破損、変形することなく面圧を受けることができ、コロとしての働きが荷重によって変化せず、荷重依存性に優れた軋み音防止表面処理剤となる。荷重依存性に優れるため、結果として軋み音防止表面処理剤の耐久性を向上させることができる。
このように擦れ合うときには粒子がコロとして働き易く、摺動時の応力低下させ、発生する軋み音を低減することができる。
The mechanism by which the stagnation-preventing surface treatment agent of the present invention estimated at the present time suppresses the wear of parts will be described.
It is thought that the particles added to the surface treatment agent form a roller state at the contact area, and the rolling of the particles reduces the sliding stress and suppresses the wear of the parts. Can be improved.
Ceramic particles have a higher hardness than conventional resin particles, so even if the contact surface pressure between two contacting articles is high, the particles can be subjected to a surface pressure with almost no damage or deformation. The surface treatment agent does not change depending on the load and is excellent in load dependency. Since it is excellent in load dependence, the durability of the surface treatment agent for preventing squeaking noise can be improved as a result.
In this way, when the particles rub against each other, the particles can easily act as a roller, reducing the stress during sliding, and reducing the squeaking noise that occurs.
平均粒径が200nmを超えるとセラミック粒子は逆に研磨剤として働き、部品の摩耗を抑制することができず、結果として軋み音を低減することができない。また、5nm未満では、コロとしての働きが低下する場合があり、軋み音を低減することが困難な場合が生じる。
なお、軋み音防止効果や耐摩耗性を考慮すると平均粒径が10〜100nmであることが好ましい。
If the average particle size exceeds 200 nm, the ceramic particles, on the other hand, act as an abrasive and cannot suppress wear of parts, and as a result, it is not possible to reduce squeaking noise. If the thickness is less than 5 nm, the function as a roller may be lowered, and it may be difficult to reduce the squeaking noise.
In view of the effect of preventing squeaking noise and wear resistance, the average particle size is preferably 10 to 100 nm.
セラミック粒子の形状は、上述した所望の効果を得るために、球状であることが必要であり、真球状であることが好ましい。
セラミック粒子の全部又は一部が1次粒子であることが望ましい。1次粒子であると、粒子内部に隙間がほぼ無いため、荷重依存性に優れたものとなる。
The shape of the ceramic particles needs to be spherical in order to obtain the above-described desired effect, and is preferably spherical.
It is desirable that all or part of the ceramic particles are primary particles. When the particles are primary particles, there are almost no gaps inside the particles, so that the load dependency is excellent.
セラミックス粒子としては、上述したような種々のものを利用できるが、セラミック粒子の耐久性や硬度、コストなどの観点から、酸化ケイ素や酸化アルミニウムが好ましく、例えば気相法により得られる酸化ケイ素や酸化アルミニウムは粒径を小さくできる、更には表面に水酸基が多く凝集力が高く、部品表面に付着し易いなどの観点からより好ましい。 As the ceramic particles, various particles as described above can be used, but from the viewpoint of durability, hardness, cost, etc. of the ceramic particles, silicon oxide and aluminum oxide are preferable. For example, silicon oxide or oxide obtained by a vapor phase method can be used. Aluminum is more preferable from the standpoint that the particle size can be reduced, and that the surface has many hydroxyl groups and has high cohesive strength and is easily attached to the surface of the component.
表面処理剤100重量部に対し、セラミック粒子の添加量が0.5〜70重量部であることが好ましく、5〜20重量部であることがより好ましい。添加量が0.5重量部未満であると軋み音低減効果が不十分であり、70重量部を超えると粘度が高くなり皮膜形成(塗布)が困難となる。 The amount of ceramic particles added is preferably 0.5 to 70 parts by weight and more preferably 5 to 20 parts by weight with respect to 100 parts by weight of the surface treatment agent. If the amount added is less than 0.5 parts by weight, the effect of reducing the squeaking noise is insufficient, and if it exceeds 70 parts by weight, the viscosity increases and film formation (application) becomes difficult.
このようにして得られる本発明の軋み音防止表面処理剤は、現状の表面処理剤と同様の形態で使用することができる。現状の使用態様とは、例えばプラスチック成形体の表面又は塩化ビニルシート若しくは熱可塑性オレフィン系シートの表面にエアスプレー、はけ塗り、ローラー塗り、浸漬塗装、グラビア塗装などにより塗布することができる。 The squeaking noise preventing surface treatment agent of the present invention thus obtained can be used in the same form as the current surface treatment agent. With the present use aspect, it can apply | coat to the surface of a plastic molding or the surface of a vinyl chloride sheet or a thermoplastic olefin type sheet | seat by air spray, brush coating, roller coating, dip coating, gravure coating, etc., for example.
本発明の軋み音防止表面処理剤の被塗対象物である自動車の内装部品としては、例えばインストルメントパネル、ドアトリム、ピラー、サンバイザー、メータークラスター、コンソールボックス、シートレザー等の部品が挙げられる。これらの部品の材質は、例えば各種プラスチック、ゴム、金属、ガラス等が挙げられる。 Examples of interior parts for automobiles that are objects to be coated with the surface treatment agent for squeaking noise according to the present invention include parts such as instrument panels, door trims, pillars, sun visors, meter clusters, console boxes, and seat leather. Examples of the material of these parts include various plastics, rubber, metal, and glass.
