Title (EN) HOT MELT ADHESIVE
(FR) ADHÉSIF THERMOFUSIBLE
(JA) ホットメルト接着剤
Abstract:
(EN) One aspect of the present invention is a hot melt adhesive containing a thermoplastic polymer, a tackifier, and a softening agent, wherein: the thermoplastic polymer contains a copolymer comprising a first block which comprises a conjugated diene-based compound and a second block which comprises a vinyl aromatic hydrocarbon and/or a hydrogenated product of the copolymer; the copolymer is such that the content of the second block is less than 30 mass% and the content of a diblock structure of the first block and the second block is 10 mass% or more; the content of the copolymer and the hydrogenated product thereof is 55 mass% or more relative to the overall quantity of the thermoplastic polymer; and the content of the softening agent is 15-30 parts by mass relative to 100 parts by mass of the hot melt adhesive.
(FR) Un aspect de la présente invention concerne un adhésif thermofusible contenant un polymère thermoplastique, un tackifiant et un plastifiant, le polymère thermoplastique contenant un copolymère comprenant un premier bloc qui comprend un composé à base de diène conjugué et un second bloc qui comprend un hydrocarbure aromatique vinylique et/ou un produit hydrogéné du copolymère; le copolymère est tel que le contenu du second bloc est inférieur à 30 % en masse et que le contenu d'une structure dibloc du premier bloc et du second bloc est de 10 % en masse ou plus; la teneur du copolymère et de son produit hydrogéné étant de 55 % en masse ou plus par rapport à la quantité globale du polymère thermoplastique; et la teneur du plastifiant est de 15 à 30 parties en masse par rapport à 100 parties en masse de l'adhésif thermofusible.
(JA) 本発明の一局面は、熱可塑性ポリマーと、粘着付与剤と、軟化剤とを含むホットメルト接着剤であって、前記熱可塑性ポリマーは、共役ジエン系化合物からなる第1ブロックとビニル系芳香族炭化水素からなる第2ブロックとからなる共重合体、及び前記共重合体の水素化物の少なくとも一方を含み、前記共重合体は、前記第2ブロックの含有量が30質量%未満であり、前記第1ブロックと前記第2ブロックとのジブロック体の含有量が10質量%以上である共重合体であって、前記共重合体及び前記共重合体の水素化物の含有量が、前記熱可塑性ポリマー全量に対して、55質量%以上であり、前記軟化剤の含有量が、前記ホットメルト接着剤100質量部に対して、15~30質量部であるホットメルト接着剤である。
