Abstract
Description
接着剤を用いる場合、通常は、両方の接続面に接着剤を塗布した後、乾燥するまで両者が押し合わされる。乾燥または硬化に必要な時間は、接着剤によって異なる。
同様の方法で、木製またはそれと同等の材料からなる物体を、合成材料からなる物体に接続することができる。
デュロプラスチックへと変換されることで、架橋、そして重合化が生じ、ひいては、発熱しながら進行可能な化学反応が生じる。擦り合いにより生じた摩擦熱がこの化学変化を促進させ、熱可塑性樹脂の場合のように硬化を妨げることがない。
熱可塑性樹脂の接続手段の場合とは異なり、接続手段を硬化させるために熱を取り除くことを必要とせず、したがって、方法のパラメータを適切に選択することで、休止期間を実質的にゼロとすることができる。ここで休止期間とは、摩擦発生の終了後2つの物体を一体に保持しておかなければならない期間であり、摩擦発生の終了とは、少なくとも一方の物体の機械的刺激の終了を意味する。
このようにして、2つの物体を接続するために必要な時間を、従来技術と比較して、大幅に減じることができる。
中断していた重合化および(または)架橋化が、摩擦熱を与えることで再開される。その際、重合化したポリマーまたは樹脂が未だ液化されていない場合は最初に溶けて、その後、反応が非可逆的に進んで完了し、いわゆるC段階またはレジトール段階となる。
ポリマーまたは樹脂について、最終的な固体の段階前の、液体の中間段階が存在することにより、2つの接続面を覆うことが容易になり、したがって、接続手段と接続面との強固な接続が可能となる。
これらの樹脂のデュロプラスチックへの変換は、重縮合または重付加によってもたらされる。
紙の重さはほぼ10〜180g/m2であり、ポリマーまたは樹脂の含有量は、紙の重さに対して20〜350%であることが好ましい。
フリースの重さはほぼ10〜120g/m2であり、ポリマーまたは樹脂の含有量は、フリースの重さに対して40〜200%であることが好ましい。
そのような平坦状またはロープ状の物体は、取扱いが容易な点で有利である。
別例として、接続手段2は、液体または粉体とすることが可能である。しかし、その場合には、液体または粉体が飛ばされることのないように、物体1を矢印A方向に十分にゆっくりと近づけるべきである。その場合でも高速な接近を可能とするために、加熱または粘着剤(sticking material)の添加により、粉体の粒子間の接着性を高めることができる。このようにして、飛び散りを減じ、または全体として避けることができる。
最後に、少なくとも1のポリマーまたは樹脂が含浸された平坦物体形状の接続手段(特に、紙またはフリース)や、物体3に接続手段2を一体的に備えた構成(例えば、物体3との同時押出成形)を採用することも可能である。
次の樹脂およびポリマーがとくに適している。ユリアホルムアルデヒド樹脂、メラミンホルムアルデヒド樹脂、メラミンユリアホルムアルデヒド樹脂、メラミンユリアフェノールホルムアルデヒド樹脂、フェノールホルムアルデヒド樹脂、レソルシンホルムアルデヒド樹脂、架橋可能なイソシアネートジオール樹脂、エポキシ樹脂、架橋可能なポリウレタンに重合可能な樹脂、および架橋可能なポリウレタン。
摩擦熱によって、接続手段2の全体、または少なくとも上述した少なくとも1のポリマーまたは樹脂がデュロプラスチックに変換される。その際、最初溶融されて、接続面11および31を最大限覆うことが好ましい。
例えば木製の多孔性物体1、3に対して、溶けた接続手段2、ポリマーまたは樹脂は、それぞれ、物体1から負荷される圧力によって孔内に入り込み、これによって、接続手段2と物体1、3との接続が大幅に強化される。
物体1の機械的刺激や、矢印A方向への圧力の負荷は、この分野におけるどのような手段を用いて実現してもよい。
この例では、物体1、3は木製であって、接続手段2は、ユリアホルムアルデヒド樹脂で構成されている。
Claims (14)
