Description
本発明は、ホットメルト接着剤を取り扱うための部材に関する。 The present invention relates to a member for handling a hot melt adhesive.
壁紙や合板の貼り合わせ等に用いられるホットメルト接着剤とは、室温で固形状をなしている１００％固形分の熱可塑性ポリマーをベースにした接着性混合物であり、一旦加熱溶融した後に冷却することにより強力な接着効果を発揮するものである。ホットメルト接着剤は古くから材料開発がなされ、近年もその改良が進められており、例えば、繰り返し溶融・固化させても性能低下の少ないホットメルト接着剤などが提案されている（特許文献１参照）。 Hot melt adhesive used for wallpaper and plywood bonding is an adhesive mixture based on a 100% solid thermoplastic polymer that is solid at room temperature. In this way, a strong bonding effect is exhibited. Hot melt adhesives have been developed for a long time, and have been improved in recent years. For example, hot melt adhesives with little performance deterioration even when repeatedly melted and solidified have been proposed (see Patent Document 1). ).
このようなホットメルト接着剤を開発、試作、製造するに際し、ホットメルト接着剤がその取扱い部材に付着して剥がれ難いために、取扱いが非常に困難である。取扱い部材からのホットメルト接着剤の剥離が容易にできることや、使用後の取扱い部材が簡易な手入れだけで再利用できることが求められている。 When developing, prototyping, and manufacturing such a hot melt adhesive, it is difficult to handle because the hot melt adhesive adheres to the handling member and hardly peels off. It is required that the hot-melt adhesive can be easily peeled off from the handling member and that the handling member after use can be reused by simple care.
そこで、取扱い部材の表面にシリコン系樹脂からなるシートをしいて非粘着性を付与することが考えられる。しかしながら、シリコン系樹脂からなるシートを取扱い部材に固定することは難しく、シートそのものが取扱い部材から外れ易いために取扱いそのものが困難であり、交換も頻繁に行わなくてはならないという問題があった。 Therefore, it is conceivable to provide a non-adhesiveness by applying a sheet made of a silicon-based resin on the surface of the handling member. However, it is difficult to fix a sheet made of a silicon-based resin to the handling member, and the sheet itself is easily detached from the handling member, so that the handling itself is difficult, and there is a problem that replacement must be performed frequently.
そこで、取扱い部材の表面に、シリコン系樹脂を含有する塗料を塗布して、非粘着性を向上させることが考えられる。しかしながら、シリコン系樹脂塗料を塗布した取扱い部材は、使用初期の段階では、ある程度の非粘着性は確保されるが、塗膜自体の強度が不十分であるため、何度もホットメルト接着剤が付着・剥離したり、汚れ除去のための手入れをする際に塗膜が損傷し易く、比較的短時間で塗膜特性が失われてしまうという問題があった。 Therefore, it is conceivable to improve the non-adhesiveness by applying a coating containing a silicone resin to the surface of the handling member. However, in the initial stage of use, the handling member to which the silicone resin coating is applied is secured to some extent, but the strength of the coating film itself is insufficient. There is a problem that the coating film is easily damaged when it is adhered and peeled off or is cleaned for removing dirt, and the characteristics of the coating film are lost in a relatively short time.
そこで、塗膜の硬度と耐久性を高めるため、補強剤として特定の骨材（フィラー）を添加したシリコン系樹脂塗料が市販されているが、補強剤として添加している骨材（フィラー）は非粘着性を有さないため、骨材の添加量が多くなると塗膜の非粘着性が低下する。よって、骨材の添加量には自ずと限界があり、塗膜の硬度および耐久性の向上はあまり望めないという問題があった。
本発明の課題は、非粘着性、耐久性、耐摩耗性、耐傷付き性などに優れ、また、簡易な手入れだけで、長時間使用しても使用初期の優れた特性を維持することのできるホットメルト接着剤用取扱い部材を提供することにある。 The object of the present invention is excellent in non-adhesiveness, durability, abrasion resistance, scratch resistance, etc., and can maintain excellent characteristics in the initial stage of use even for a long time by simple care. It is to provide a handling member for hot melt adhesive.
本発明者は、鋭意研究を進めた結果、三層構造のシリコン系樹脂含有塗膜を取扱い部材の基材上に形成することにより、上記課題が解決されることを見出し、本発明を完成するに至った。 As a result of diligent research, the present inventors have found that the above-mentioned problems can be solved by forming a three-layered silicon-based resin-containing coating film on the base material of the handling member, and complete the present invention. It came to.
