Abstract

L'invention concerne un matériau de préparation de bouchon d'oreille apte à libérer des ions négatifs, un bouchon d'oreille d'insonorisation en matériau PU et un procédé de préparation associé. Le matériau de préparation comprend de 40 à 60 parties en poids d'un prépolymère d'isocyanate et de 40 à 60 parties en poids d'un mélange d'ions négatifs, le mélange d'ions négatifs comprenant de 7 à 13 parties en poids d'une poudre à ions négatifs, de 35 à 50 parties en poids d'eau purifiée, et de 45 à 60 parties en poids d'une émulsion d'acrylate. Par rapport à l'état de la technique, le bouchon d'oreille en matériau PU (polyuréthane) à ions négatifs n'engendre aucune pollution environnementale étant donné qu'aucun solvant volatil n'est ajouté pendant le processus de production ; lorsqu'il est utilisé, il peut émettre des ions négatifs dans l'environnement, lesquels sont facilement absorbés par un corps humain, ce qui permet d'augmenter la valeur des bouchons d'oreille ; et lorsque ledit bouchon d'oreille est porté pendant une longue période, il est facile pour le corps humain d'absorber les ions négatifs qu'il émet, et les ions négatifs pénètrent à travers la barrière hémato-encéphalique du corps humain dans le corps humain pour exercer leurs effets biologiques, réduisent les états d'oppression thoracique, de vertiges et de fatigue, provoqués par un manque d'ions négatifs, du corps humain, augmentent l'efficacité de travail et améliorent l'état de santé.
