Abstract
(EN)
A light reflecting material, a reflecting layer and a preparation method therefor; the light reflecting material comprises glass powder particles (1), diffuse reflection particles, ultra-fine nano particles, and an organic carrier; the particle size of the glass powder particles (1) is ≤ 5 μm, the particle size of the diffuse reflection particles is 0.1 μm to 0.2 μm, and the particle size of the ultra-fine nano particles is 0.01 μm to 0.05 μm. The glass powder particles (1), diffuse reflection particles and ultra-fine nano particles the particle sizes of which decrease progressively in sequence by one order of magnitude are used as the raw materials of the reflecting layer; without decreasing the adhesion between the reflecting layer and a substrate, the surface area within the reflecting layer that may cause reflection or refraction is increased to obtain better reflectivity.

L'invention concerne un matériau réfléchissant la lumière, une couche réfléchissante et son procédé de préparation ; le matériau réfléchissant la lumière comprend des particules de poudre de verre (1), des particules de réflexion diffuse, des nanoparticules ultrafines et un support organique ; la taille de particule des particules de poudre de verre (1) est ≤ 5 μm, la taille de particule des particules de réflexion diffuse est de 0,1 µm à 0,2 µm et la taille de particule des nanoparticules ultrafines est de 0,01 µm à 0,05 µm. Les particules de poudre de verre (1), les particules de réflexion diffuse et les nanoparticules ultrafines dont les tailles de particules diminuent progressivement en séquence d'un ordre de grandeur sont utilisées comme matières premières de la couche réfléchissante ; sans diminuer l'adhérence entre la couche réfléchissante et un substrat, l'aire de surface à l'intérieur de la couche réfléchissante qui peut provoquer une réflexion ou une réfraction est augmentée pour obtenir une meilleure réflectivité.

一种光反射材料、反射层及其制备方法,光反射材料包含玻璃粉颗粒(1)、漫反射颗粒、超细纳米颗粒以及有机载体;玻璃粉颗粒(1)的粒径≤5μm,漫反射颗粒的粒径为0.1μm~0.2μm,超细纳米颗粒的粒径为0.01μm~0.05μm。采用粒径大小依次递减一个数量级的玻璃粉颗粒(1)、漫反射颗粒、超细纳米颗粒作为反射层的原材料,在不降低反射层与基板之间附着力的前提下,增加了反射层内可造成反射或折射的表面面积,从而获得了更优良的反射率。
