Description
本発明は、ラミネート用接着剤として用いられるハイソリッド型接着剤に関する。 The present invention relates to a high solid type adhesive used as an adhesive for lamination.
軟包装材には様々な用途があるが、その中でも高い接着物性を要求されるのが、洗剤、シャンプー、リンス等の詰め替えスタンディングパウチ用の包装材である。これらの内容物には、油分、界面活性剤の他、低分子量の香料が使用されており、これが接着剤層を侵してデラミネーション等の不良に繋がり、問題となっていた。 Soft packaging materials have various uses, and among them, the ones that require high adhesive properties are packaging materials for refillable standing pouches such as detergents, shampoos and conditioners. In addition to oils and surfactants, low-molecular-weight fragrances are used in these contents, which has been a problem since it attacks the adhesive layer and leads to defects such as delamination.
従来日本国内では、シャンプー、リンス等では諸外国と比較し香りが少ないものが好まれていたが、近年消費者の嗜好が変わり、より香りの強い物を求める傾向が出てきた。そのため、外資系メーカーを中心に諸外国と同様に香りが強いものを製造してきており、従来の包装材では包装材に浸透してくる内容物に対するラミネート用接着剤の耐性（耐内容物性）が不足する結果となっている。 Conventionally, in Japan, shampoos, rinses, etc. were preferred to have less fragrance than those in other countries, but in recent years, consumers' taste has changed, and there is a tendency to demand more fragrant products. For this reason, foreign-affiliated manufacturers are mainly producing products with a strong fragrance as in other countries, and conventional packaging materials have a resistance (content resistance) of the laminating adhesive to the contents that permeate the packaging materials. The result is lacking.
一方、包装材のコスト削減の要求、環境への配慮、作業環境改善のため、接着剤のハイソリッド化による溶剤使用量削減が可能な包装材が求められている。
接着剤のハイソリッド化では、溶剤配合割合を削減しても塗工可能粘度にするため、接着剤樹脂を従来より低分子量化する必要があるが、低分子量化は耐香料性とは逆行する方向であり、両立は困難となっている。
そのため、このような高物性用途にハイソリッド接着剤が使用されることはこれまで無かったが、溶剤回収設備を持たない工場等を中心にニーズが高まっている。
On the other hand, in order to reduce the cost of packaging materials, consider the environment, and improve the working environment, there is a demand for packaging materials that can reduce the amount of solvent used by making the adhesive high solid.
In high-solidity adhesives, the adhesive resin must have a lower molecular weight than before in order to achieve a coatable viscosity even if the solvent blending ratio is reduced, but lowering the molecular weight is contrary to perfume resistance. It is a direction, and it is difficult to achieve both.
Therefore, high solid adhesives have never been used for such high physical property applications, but needs are increasing mainly in factories without solvent recovery equipment.
特許文献１には、香料、界面活性剤等の内容物を充填した場合においても、経時的な接着強度の低下がなく、長期にわたって強い接着強度を維持でき、粘度が低く塗工性にも優れた接着剤組成物で接着され形成された耐薬品性に優れた非食品包装用ラミネートフィルム積層体として、ガラス転移温度が４０℃以上の有機ポリオール５〜５０重量％及びガラス転移温度が４０℃未満の有機ポリオール（但し、その分子中にカルボキシル基を有しない。）９５〜５０重量％からなる混合物、シランカップリング剤並びに有機ポリイソシアネートを含有する組成物で接着され形成された非食品包装用ラミネートフィルム積層体が記載されている。 In Patent Document 1, even when the contents such as a fragrance and a surfactant are filled, the adhesive strength does not decrease with time, the strong adhesive strength can be maintained for a long time, the viscosity is low, and the coatability is excellent. As a laminated film laminate for non-food packaging excellent in chemical resistance formed by adhering with an adhesive composition having an organic polyol having a glass transition temperature of 40° C. or higher of 5 to 50% by weight and a glass transition temperature of less than 40° C. Non-food packaging laminate formed by adhering with a composition containing 95 to 50% by weight of an organic polyol (however, having no carboxyl group in its molecule), a silane coupling agent and an organic polyisocyanate. A film laminate is described.
また、特許文献２には、従来のハイソリッド型接着剤では達成できなかった初期凝集力及び硬化後の物性を向上させ、従来の低固形成分型接着剤と同等の性能を有するハイソリッド型接着剤として、数平均分子量が１０，０００以下であり、一分子当り１．４〜１．８個の水酸基を有するポリオール成分並びにイソシアネート硬化剤成分とからなり、該ポリオール成分と該イソシアネート硬化剤成分は、該ポリオール成分中の水酸基に対して該イソシアネート硬化剤中のイソシアネート基が０．８〜５．０当量の割合となるように配合された固形分が４０質量％以上であることを特徴とするハイソリッド型接着剤組成物が記載されている。 Further, in Patent Document 2, a high solid type adhesive having improved performance in initial cohesive force and physical properties after curing, which cannot be achieved by a conventional high solid type adhesive, and having performance equivalent to that of a conventional low solid component type adhesive. The agent has a number average molecular weight of 10,000 or less and is composed of a polyol component having 1.4 to 1.8 hydroxyl groups per molecule and an isocyanate curing agent component, and the polyol component and the isocyanate curing agent component are The solid content of the isocyanate component in the isocyanate curing agent is 40% by mass or more with respect to the hydroxyl groups in the polyol component. A high solids adhesive composition is described.
