  荧光增白剂在油漆中的作用
  Function of Fluorescent Whitener in Paint
  荧光增白剂在油漆中的作用是提高产品的白度或鲜艳度,改善产品的外观和使用性能。
  The function of fluorescent whitening agent in paint is to improve the whiteness or brightness of the product and the appearance and performance of the product.
  随着人们生活水平的提高和科学技术的进步,油漆,如白色氨基烘漆、聚氨酯磁漆、醇酸磁漆等的作用已经不再是简单的保护被漆物体的表面,同时还具有美化漆物表面,给人以美感的作用。很多透明或白色油漆有一种固有的黄色色调,过去在制造油漆的过程中,为了获得白色或淡色外观,尽量选择浅色透明基质和稳定而且白度高的白色颜料,除此之外,在白色漆中通常还加入一定量的蓝色颜料,即所谓的“上蓝”,利用蓝色和油漆黄色的互补作用来增加油漆的白度,但这种白色的亮度不高,有点灰暗。
  With the improvement of people's living standards and the progress of science and technology, the role of paints, such as white amino baking paint, polyurethane paint, alkyd paint and so on, is no longer simply to protect the surface of painted objects, but also to beautify the surface of paints, giving people a sense of beauty. Many transparent or white paints have an inherent yellow tone. In the past, in order to obtain a white or light appearance, light transparent matrix and stable and high whiteness white pigments were selected as far as possible. In addition, a certain amount of blue pigments, called "blue-up", were usually added to white paints, which increased the paint by using the complementary effect of blue and paint yellow. Whiteness, but this kind of white brightness is not high, a little gray.
  荧光增白剂作为一种荧光染料已广泛地应用在白色或淡色的油漆中,利用荧光增白剂可吸收紫外光而发射蓝紫色荧光,从而与漆膜表面的黄光混合而变为白色光,使漆膜表面趋于全反射,在人的视觉上白色油漆看起来更加洁白、亮丽;浅色油漆看起来更加艳丽夺目,极大地改善了产品的外观。荧光增白剂在油漆中的另一个用途也是利用其可吸收紫外光而发射蓝紫色荧光的作用,在提高白色油漆白度或浅色油漆鲜艳度的同时,减少紫外线对油漆中颜料的损害,提高油漆的耐光性,延长油漆在室外及日光环境下的使用寿命。

  As a fluorescent dye, fluorescent whitening agent has been widely used in white or light-colored paints. It can absorb ultraviolet light and emit blue-purple fluorescence, thus mixing with the yellow light on the surface of the paint film and turning it into white light, which makes the surface of the paint tend to be totally reflective, and makes the white paint look more white and bright in human vision; the light-colored paint looks more brilliant and tremendous. The appearance of the product was improved. Another use of fluorescent whitening agent in paint is to use it to absorb ultraviolet light and emit blue-purple fluorescence. It can improve whiteness of white paint or brightness of light paint, at the same time, reduce the damage of ultraviolet to paint, improve the light resistance of paint, and prolong the service life of paint in outdoor and sunlight environment.
