要約
(EN) Provided is a metal-resin bonded body with which excellent bonding strength can be achieved, strength is not reduced after being subjected to a durability test, and excellent bonding strength can be maintained for a long time. This metal-resin bonded body is provided with: a metal base material: an oxygen-containing film which includes oxygen, and which is formed on a surface of the metal base material by being subjected to processing in which the oxygen content thereof is intentionally increased; and a resin moulded body which is bonded to a top of the oxygen-containing film, and which is formed using a thermoplastic resin composition including an additive compound having a specific functional group that reacts with the oxygen-containing film. The functional group in the additive compound is at least one selected from the group consisting of a carboxyl group and salts and esters thereof, an epoxy group, a glycidyl group, an isocyanate group, a carbodiimide group, an amino group and salts thereof, and an acid anhydride group and esters thereof.
(FR) L'invention fournit un corps lié métal/résine qui tout en développant une excellente résistance, et sans baisse de résistance après essai de fatigue, permet de préserver une excellente résistance de liaison sur le long terme. Ce corps lié métal/résine possède : un matériau de base métallique ; un revêtement à teneur en oxygène comprenant un oxygène qui est formé à la surface du matériau de base métallique par exécution d'un traitement augmentant volontairement la teneur en oxygène ; et un corps moulé de résine qui est lié sur ce revêtement à teneur en oxygène, et qui est formé par une composition de résine thermodurcissable comprenant un composé additif doté d'un groupe fonctionnel spécifique réagissant avec le revêtement à teneur en oxygène. Le groupe fonctionnel dudit composé additif consiste en au moins un élément choisi dans un groupe constitué d'un groupe carboxyle, d'un sel de celui-ci ainsi que d'un ester de celui-ci, d'un groupe époxy, d'un groupe glycidylique, d'un groupe isocyanate, d'un groupe carbodiimide, d'un groupe amino ainsi que d'un sel de celui-ci, et d'un groupe anhydride acide ainsi que d'un sel de celui-ci.
(JA)  優れた接合強度を発現すると共に耐久試験後に強度低下を起こさず、長期に亘って優れた接合強度を維持し得る金属樹脂接合体を提供する。 金属基材と、この金属基材の表面に、意図的に酸素含有量を増やす処理を施すことにより形成された酸素を含有する酸素含有皮膜と、この酸素含有皮膜の上に接合され、酸素含有皮膜と反応する特定の官能基を有する添加剤化合物を含有する熱可塑性樹脂組成物で形成された樹脂成形体とを有する金属樹脂接合体であって、前記添加剤化合物の官能基が、カルボキシル基及びその塩及びそのエステル、エポキシ基、グリシジル基、イソシアネート基、カルボジイミド基、アミノ基及びその塩、並びに、酸無水物基及びそのエステルからなる群の中から選ばれる少なくとも1種である。
