Abstract

L'invention concerne un cuir artificiel transmettant la lumière, un procédé de préparation associé et un intérieur d'automobile. Le procédé de préparation associé comprend les étapes suivantes consistant à : mélanger une matière première primaire contenant un toner ayant une taille de particule de 0,5 à 10 µm, une poudre de polymère et un plastifiant, et l'agiter, la broyer, la filtrer et la démousser pour obtenir une matière première de pigment transmettant la lumière ; mélanger la matière première de pigment transmettant la lumière avec une matière première secondaire contenant une poudre de polymère, un plastifiant, un stabilisant et un additif inorganique, et l'agiter, la filtrer et la démousser pour obtenir une matière première de couche de peau transmettant la lumière ; et utiliser un tissu de base, une matière première de colle, une matière première de couche de support et la matière première de couche de peau transmettant la lumière pour préparer, afin d'obtenir un produit semi-fini de cuir artificiel formé par la couche de peau transmettant la lumière, une couche de support, une couche de colle et le tissu de base disposés successivement ; et revêtir d'un agent de traitement de surface la surface de la couche de peau transmettant la lumière, de façon à obtenir un cuir artificiel transmettant la lumière. Le toner dans la matière première de couche de peau transmettant la lumière utilise un toner ayant un diamètre de particule nanométrique, de sorte que le degré auquel le toner obstrue la lumière est réduit, et le cuir artificiel préparé est assuré d'avoir une certaine transmittance de la lumière.
