Title (EN) LONG-LASTING LIGHT CONVERSION FILM AND PREPARATION METHOD THEREFOR
(FR) FILM DE CONVERSION DE LUMIÈRE DE LONGUE DURÉE ET SON PROCÉDÉ DE PRÉPARATION
(ZH) 一种使用寿命长的转光膜及其制备方法
Abstract:
(EN) A long-lasting light conversion film and a preparation method therefor. The light conversion film comprises a first protective layer, a light conversion layer arranged on the first protective layer, and a second protective layer arranged on the light conversion layer. The protective layers consist of at least one plastic layer and at least one isolation layer. The preparation method for the light conversion film is as follows: 1) respectively preparing a plastic layer premix and an isolation layer premix; 2) uniformly mixing a matrix resin, a light conversion agent, a lubricant, a light stabiliser and an antioxidant to obtain a light conversion layer premix; 3) adding the plastic layer premix, the isolation layer premix and the light conversion layer premix to a co-extruder, and performing multi-layer co-extrusion. The isolation layer in the light conversion film effectively blocks moisture and oxygen in the air, and prevents the light conversion agent in the light conversion layer from coming into contact with moisture and oxygen and breaking down, thereby increasing the stability of the light conversion agent, and significantly extending the service life of the light conversion film.
(FR) L'invention concerne un film de conversion de lumière de longue durée et son procédé de préparation. Le film de conversion de lumière comprend une première couche de protection, une couche de conversion de lumière disposée sur la première couche de protection, et une seconde couche de protection disposée sur la couche de conversion de lumière. Les couches de protection sont constituées d'au moins une couche plastique et d'au moins une couche d'isolation. Le procédé de préparation du film de conversion de lumière comprend les étapes consistant à : 1) préparer respectivement un pré-mélange de couche plastique et un pré-mélange de couche d'isolation; 2) mélanger uniformément une résine de matrice, un agent de conversion de lumière, un lubrifiant, un stabilisant de lumière et un antioxydant pour obtenir un pré-mélange de couche de conversion de lumière; 3) ajouter le pré-mélange de couche plastique, le pré-mélange de couche d'isolation et le pré-mélange de couche de conversion de lumière à une co-extrudeuse, et effectuer une coextrusion multicouche. La couche d'isolation dans le film de conversion de lumière bloque efficacement l'humidité et l'oxygène dans l'air, et empêche l'agent de conversion de lumière dans la couche de conversion de lumière d'entrer en contact avec l'humidité et l'oxygène et de se décomposer, augmentant ainsi la stabilité de l'agent de conversion de la lumière et prolongeant considérablement la durée de vie du film de conversion de lumière.
(ZH) 一种使用寿命长的转光膜及其制备方法,该转光膜包括第一保护层、设置在第一保护层上的转光层和设置在转光层上的第二保护层;所述的保护层由至少一层塑料层和至少一层隔离层组成。该转光膜的制备方法如下:1)分别制备塑料层预混料和隔离层预混料;2)将基体树脂、转光剂、润滑剂、光稳定剂和抗氧剂充分混合均匀,得到转光层预混料;3)将塑料层预混料、隔离层预混料和转光层预混料加入共挤出机中,进行多层共挤出。该转光膜中的隔离层可以很好地阻隔空气中的水分和氧气,避免转光层中的转光剂与水分和氧气接触而发生分解,提高了转光剂的稳定性,大幅延长了转光膜的使用寿命。
