Description

本発明は、接着剤による接着構造およびその接着方法、ならびにそれに用いる被着体に関するものである。   The present invention relates to an adhesive structure using an adhesive, an adhesion method therefor, and an adherend used therefor.

自動車ガラス用接着剤は、自動車用ガラスに対し、インナーミラー取付用ブラケット、モール、プロテクター、位置決め用基準ピン、ヒンジ等の各部材を取り付けるために使用されるものであり、通常、エポキシ系、ウレタン系、シリコーン系、変性シリコーン系等の接着剤が使用されている(例えば特許文献1参照)。その際、接着剤層の厚みを制御することは非常に重要である。このため、従来は、被着体の接着面にエンボス加工のような突起をつけたり、接着剤にガラスビーズなどの大口径フィラーを内包したりして、接着剤層の厚みを制御している。   Automobile glass adhesive is used to attach inner mirror mounting brackets, moldings, protectors, positioning reference pins, hinges, and other parts to automotive glass. Adhesives such as those based on silicone, silicone and modified silicone are used (for example, see Patent Document 1). At that time, it is very important to control the thickness of the adhesive layer. For this reason, conventionally, the thickness of the adhesive layer is controlled by providing protrusions such as embossing on the adhesion surface of the adherend or encapsulating a large-diameter filler such as glass beads in the adhesive.

しかし、接着に際しては、接着剤層の厚みを制御するのはもちろんのこと、被着体の周囲からの接着剤のはみ出しを防止することも要望されている。すなわち、接着剤を多く使用した場合、接着剤が被着体の周囲からはみ出すと、外観見栄えが悪くなるだけでなく、はみ出した接着剤が他の部材取付けの邪魔になる、はみ出した接着剤を取り除く手間が増えるといった問題点もある。
特開平11−92735号公報
However, at the time of bonding, not only the thickness of the adhesive layer is controlled but also the prevention of the adhesive from protruding around the adherend is desired. In other words, when a large amount of adhesive is used, if the adhesive protrudes from the periphery of the adherend, not only the appearance looks bad, but the protruding adhesive interferes with the mounting of other members. There is also the problem that the time and effort to remove increases.
JP-A-11-92735

そこで本発明の主たる課題は、接着剤使用量が多い場合であっても接着剤のはみ出しを効果的に防止しうる技術を提供することにある。   Therefore, a main problem of the present invention is to provide a technique capable of effectively preventing the adhesive from protruding even when the amount of the adhesive used is large.

<請求項1記載の発明>
第1の被着体に対し、接着剤を介して第2の被着体を接着してなる構造において、
少なくとも一方の被着体の接着面に、接着時に接着面に沿って拡がる接着剤を受け入れ、接着剤の拡がりを抑制する凹部を形成してなることを特徴とする接着剤による接着構造。
<Invention of Claim 1>
In the structure formed by adhering the second adherend to the first adherend via an adhesive,
A bonding structure using an adhesive, wherein an adhesive that spreads along the bonding surface during bonding is formed on the bonding surface of at least one adherend, and a concave portion that suppresses the spreading of the adhesive is formed.

(作用効果)
本発明においては、少なくとも一方の被着体の接着面に凹部を形成することにより、図1(a)に示すように、接着時に接着面に沿って拡がる接着剤Bのうち、余剰分が凹部3に受け入れられ溜まるようになり、例えば手作業により接着剤を塗布する場合のように接着剤使用量にバラツキがあってもはみ出しをも防止できるようになる。
(Function and effect)
In the present invention, as shown in FIG. 1 (a), by forming a recess on the adhesion surface of at least one adherend, the excess portion of the adhesive B that spreads along the adhesion surface during bonding is a recess. 3 and can be prevented from sticking out even when there is a variation in the amount of adhesive used, for example, when the adhesive is applied manually.

<請求項2記載の発明>
前記凹部の周囲に、接着剤のはみ出しを堰き止める凸部を設けてなる、請求項1記載の接着剤による接着構造。
<Invention of Claim 2>
The adhesive structure using an adhesive according to claim 1, wherein a convex portion is provided around the concave portion to block the protruding adhesive.

(作用効果)
本項記載の発明によれば、図1(b)及び(c)に示すように、接着剤Bが本発明の凹部3による受け入れ能力を超えて被着体1の周囲からはみ出しそうになっても、凸部4がこれを堰き止めることにより、接着剤Bのはみ出しを防止できるようになる。また、凸部4がスペーサーとして機能し、接着剤層の厚みを適切に制御できる。
(Function and effect)
According to the invention described in this section, as shown in FIGS. 1B and 1C, the adhesive B tends to protrude from the periphery of the adherend 1 beyond the capacity of receiving the recess 3 of the present invention. However, the protrusion 4 prevents the adhesive B from protruding by blocking the protrusion 4. Moreover, the convex part 4 functions as a spacer and can control the thickness of an adhesive bond layer appropriately.

なお、かかる凸部のみを接着面の周縁部に設けるだけでも接着剤のはみ出し防止効果は十分にあるが、図1(d)に示すように、接着剤Bの使用量が多い場合には、はみ出しを防止しきれず、反対に、はみ出しを考慮して接着剤使用量を少なくすると、接着面積の低下により接着力が低下する。つまり凸部4のみでは、接着剤塗布量についてかなりの精度が要求されるため、作業の容易性や生産効率の点では問題がある。   In addition, even if only such a convex portion is provided on the peripheral edge portion of the adhesive surface, the effect of preventing the adhesive from protruding is sufficient, but as shown in FIG. 1 (d), when the amount of adhesive B used is large, On the contrary, if the amount of the adhesive used is reduced in consideration of the protrusion, the adhesive force is reduced due to the decrease in the adhesion area. In other words, since only the convex portion 4 requires considerable accuracy with respect to the adhesive application amount, there is a problem in terms of ease of work and production efficiency.

以上のとおり、本発明によれば、接着剤使用量が多い場合であっても接着剤のはみ出しを効果的に防止できるようになる。   As described above, according to the present invention, it is possible to effectively prevent the adhesive from protruding even when the amount of the adhesive used is large.

以下、本発明の実施形態について添付図面を参照しつつ詳説する。
図2及び図3は、本発明に係る被着体の例を示している。符号2は接着面を示しており、その周縁部に凹部3が形成されている。凹部3は、接着時に接着面に沿って拡がる接着剤を受け入れ、接着剤の拡がりを抑制する作用を奏する限り、寸法、形状、配置に制限はない。ただし、接着剤を接着面2の中心部に吐出する場合を考えると、凹部3は周縁部に沿って溝状に延在させるのが好ましい。すなわち凹部3は、図2に示すように、周縁部に沿って連続的な環状溝として形成する他、図4に示すように、(a)中心部に対して四方の各周縁部に、相互不連続の線状の溝として形成したり、(b)接着剤を塗布する中心部に近い両側縁部にのみ線状の溝として形成したり、(c)中心部に対して三方の各周縁部に、相互不連続の線状の溝として形成したりすることができる。なお、図4の(c)の例では、凹部3が形成されていない一方側から張り合わせ、接着剤が凹部3のない側には拡大せず、凹部3を有する側に拡大するようにするのが好ましい。
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
2 and 3 show examples of adherends according to the present invention. Reference numeral 2 denotes an adhesive surface, and a recess 3 is formed on the peripheral edge thereof. The concave portion 3 accepts an adhesive that expands along the bonding surface during bonding, and is not limited in size, shape, and arrangement as long as it has an effect of suppressing the expansion of the adhesive. However, considering the case where the adhesive is discharged to the central portion of the bonding surface 2, the concave portion 3 is preferably extended in a groove shape along the peripheral portion. That is, the recess 3 is formed as a continuous annular groove along the peripheral edge as shown in FIG. 2, and as shown in FIG. Formed as a discontinuous linear groove, (b) formed as a linear groove only on both side edges close to the central part to which the adhesive is applied, or (c) each peripheral edge on three sides with respect to the central part It can be formed in the part as a mutually discontinuous linear groove. In the example of FIG. 4C, the adhesive is bonded from one side where the recess 3 is not formed, and the adhesive does not expand on the side where the recess 3 is not present, but expands on the side having the recess 3. Is preferred.

また、凹部3の寸法は接着面の形状、面積により適宜設定すれば良いが、深すぎると被着体の強度が局所的に低下し、幅が大きくなると、接着剤の種類にもよるが、接着強度が低下することが予想される。好ましい凹部の深さは被着体1の厚さに対して50%以下、占有面積は接着面に対し、60〜90%である。   Further, the size of the recess 3 may be appropriately set depending on the shape and area of the adhesive surface, but if it is too deep, the strength of the adherend is locally reduced, and when the width is increased, depending on the type of adhesive, It is expected that the adhesive strength will decrease. A preferable depth of the concave portion is 50% or less with respect to the thickness of the adherend 1, and an occupied area is 60 to 90% with respect to the bonding surface.

さらに、上記凹部3のみでも十分に接着剤のはみ出しを防止できるものであるが、凹部3による接着剤の受け入れ能力には限界があるため、図示のように、接着面2の周縁部に接着剤のはみ出しを堰き止める凸部4を設けるのが好ましい。この凸部4は、図示のように接着面2の周縁に沿う環状の凸条として形成するのが好ましい。凸部4の接着面2に対する突出高さおよび突出部分の幅は、接着面の形状、面積等に応じて適宜定めれば良いが、突出高さは0.1mm以上、特に0.3mm以上であるのが好ましい。かかる凸部4を設けることにより、当該被着体1の接着面2と接着対象の接着面との間に一定厚さの隙間が形成されるため、接着剤層の厚みが正確に定まるとともに、接着剤が凹部3による受け入れ能力を超えて当該被着体1の周囲からはみ出しそうになっても、これを堰き止めることができ、より確実に接着剤のはみ出しを防止できるようになる。   Furthermore, although only the concave portion 3 can sufficiently prevent the adhesive from protruding, the adhesive receiving ability by the concave portion 3 is limited. It is preferable to provide a convex portion 4 for blocking the protrusion. It is preferable to form this convex part 4 as a cyclic | annular protruding item | line along the periphery of the adhesion surface 2 like illustration. The protruding height of the convex portion 4 with respect to the bonding surface 2 and the width of the protruding portion may be appropriately determined according to the shape, area, etc. of the bonding surface, but the protruding height is 0.1 mm or more, particularly 0.3 mm or more. Preferably there is. By providing the convex portion 4, a gap with a certain thickness is formed between the adhesion surface 2 of the adherend 1 and the adhesion surface of the adhesion target, so that the thickness of the adhesive layer is accurately determined, Even if the adhesive exceeds the receiving ability of the concave portion 3 and tends to protrude from the periphery of the adherend 1, it can be dammed, and the adhesive can be prevented from protruding more reliably.

他方、本発明の第1および第2の被着体は特に限定されるものではないが、一方の被着体が自動車用ガラスであり、他方の被着体がインナーミラー取付用ブラケット、キャッチハンドル締結用ブラケット、モール、プロテクター、位置決め基準ピン等の、ヒンジ等のガラス取付部材である場合に好適であり、またこの場合、後者の取付部材にのみ凹部や凸部を設けるのが好適である。この場合におけるガラス取付部材の材質は特に限定されるものではなく、鋼鉄、ステンレス、アルミニウムなどの金属でもよく、また、PBT、PET、POM、ポリアミド樹脂などのエンジニアリングプラスティックなども使用できる。自動車用ガラスとしては自動車用の強化ガラス、黒色セラミックプリントガラス、中間層にポリビニルブチラールを使用した合せガラス等に適用でき、特に限定されない。   On the other hand, the first and second adherends of the present invention are not particularly limited, but one adherend is an automotive glass, and the other adherend is an inner mirror mounting bracket and a catch handle. It is suitable for a glass mounting member such as a hinge such as a fastening bracket, a molding, a protector, a positioning reference pin, etc. In this case, it is preferable to provide a recess or a convex only on the latter mounting member. The material of the glass mounting member in this case is not particularly limited, and may be a metal such as steel, stainless steel, or aluminum, and engineering plastics such as PBT, PET, POM, and polyamide resin can be used. The glass for automobiles can be applied to tempered glass for automobiles, black ceramic printed glass, laminated glass using polyvinyl butyral as an intermediate layer, etc., and is not particularly limited.

特に本発明は、接着面の周囲(換言すれば、一方の被着体の表面と他方の被着体の側縁とにより形成される隅角部)に他の部材が近接配置される場合、例えば図2及び3に示すインナーミラー取付用ブラケットのように、その全体がインナーミラー支持部10の蟻溝11に嵌合され、インナーミラー取付用ブラケット周囲への接着剤のはみ出しがインナーミラーの嵌合を不可能にするといった機能的な問題を発生させる場合に好適である。   In particular, in the present invention, when another member is disposed close to the periphery of the adhesion surface (in other words, the corner formed by the surface of one adherend and the side edge of the other adherend) For example, like the inner mirror mounting bracket shown in FIGS. 2 and 3, the whole is fitted into the dovetail groove 11 of the inner mirror support portion 10, and the protrusion of the adhesive around the inner mirror mounting bracket is the fitting of the inner mirror. This is suitable for the case where a functional problem such as making the connection impossible occurs.

本発明では、上記本発明の特徴機能を発揮させうる範囲内であれば如何様な接着剤を使用でき、1液でもあっても2液以上でも構わない。本発明で使用できる接着剤の例としては、シリコーン系接着剤、変性シリコーン系接着剤、ポリサルファイド系接着剤、ポリウレタン系接着剤、エポキシ系接着剤、弾性エポキシ系接着剤、第二世代アクリル(SGA)、シアノアクリレート等が挙げられる。接着剤の塗布方式は特に限定されず、使用する接着剤に最適の方式で行なうことが出来る。接着剤の塗布量は、被着体の質量や形状等に応じて適宜変更可能であるが、通常の場合には0.02〜0.1g/cm2が好ましい。 In the present invention, any adhesive can be used as long as it is within the range where the characteristic function of the present invention can be exhibited, and it may be one liquid or two liquids or more. Examples of adhesives that can be used in the present invention include silicone adhesives, modified silicone adhesives, polysulfide adhesives, polyurethane adhesives, epoxy adhesives, elastic epoxy adhesives, second generation acrylic (SGA) ), Cyanoacrylate and the like. The application method of the adhesive is not particularly limited, and can be performed by a method optimal for the adhesive to be used. The application amount of the adhesive can be appropriately changed according to the mass or shape of the adherend, but in the normal case, 0.02 to 0.1 g / cm 2 is preferable.

接着に先立って、被着体にはポリイソシアネート組成物やシランカップリング剤などの、一般的にプライマーと呼ばれるものを塗布することもできるが、本発明はこれに限定されるものではない。なお、シランカップリング剤としては、一般に、相互になじみの悪いガラス、シリカ、金属、粘土等の無機材料と高分子等の有機材料とを化学結合できる官能基を有する下記式(1)で表される有機ケイ素化合物をいう。

Prior to adhesion, the adherend may be coated with what is generally called a primer, such as a polyisocyanate composition or a silane coupling agent, but the present invention is not limited thereto. The silane coupling agent is generally represented by the following formula (1) having a functional group capable of chemically bonding an inorganic material such as glass, silica, metal, clay and the like, which are not well-suited to each other, and an organic material such as a polymer.
