荧光增白剂在油漆中的作用


网址:http://www.scvc8.com  时间:2019-04-08 15:13:08

  染料和颜料一般都是自身有颜色,是指能使其他物质获得鲜明而牢固色泽的一类有机化合物。荧光增白剂虽然被人们称为白色染料,但是其本身是无色的。从荧光增白剂的名称我们可以知道,它的功效是增白,而不是染白,换句话说,荧光增白剂想要发挥增白效果的前提是产品本身是白色。
  Dyes and pigments generally have their own colors, referring to a group of organic compounds that can give other substances a bright and firm color. Although fluorescent whitening agent is called white dye, it is colorless. From the name of fluorescent whitening agent, we can know that its effect is whitening, not dyeing. In other words, the premise of fluorescent whitening agent to play whitening effect is that the product itself is white.
  这就奇怪了,既然我的产品本身是白色的,为什么还需要用到荧光增白剂呢?其实大量的有机材料,天然的或人造的纺织品或其他的物质,如纸、塑料等,看起来并不白,通常它们吸收的蓝紫光(400~480nm)比黄光要多些,因此它们或多或少地表现出微黄色。
  This is strange, since my products are white, why do I need to use fluorescent whitening agents? In fact, a large number of organic materials, natural or artificial textiles or other materials, such as paper, plastic, etc., do not look white. Usually they absorb more blue-violet light (400-480 nm) than yellow light, so they are more or less slightly yellow.
  荧光增白剂通过某种方法上染到有一定白度的基质(如纺织品、塑料、纸张、洗涤剂等)上,这种基质在日光(或含有足够紫外光的光源)的照射下,吸收了日光中肉眼看不见的紫外光(约340~380nm)的能量,然后再以极明亮、艳丽的蓝紫色荧光(约410~460nm)发射出来。这种蓝紫色荧光与基质上的微黄色光混合(黄为蓝紫色的补色)得到白光,而具有增白效果。由于被荧光增白剂增白的基质反射可见光的能力增强,因而基质的白度和亮度增加了,使被增白的基质看上去具有洁白、悦目、明亮的感觉。由此也可知荧光增白剂的增白是光学上的补色增亮,而非染色。
  Fluorescent whitening agent is dyed to a certain degree of whiteness matrix (such as textiles, plastics, paper, detergents, etc.) by some method. This matrix absorbs the energy of the invisible ultraviolet light (about 340-380 nm) in the sun under the irradiation of sunlight (or containing enough ultraviolet light source), and then emits with very bright, brilliant blue-purple fluorescence (about 410-460 nm). The blue-purple fluorescence is mixed with the yellowish light on the substrate (yellow is the complementary color of blue-purple) to obtain white light, which has the whitening effect. The brightness and brightness of the matrix whitened by fluorescent whitening agent are increased due to its ability to reflect visible light, which makes the whitened matrix look white, pleasant and bright. It can be concluded that the brightening of fluorescent whitening agent is optical brightening, not dyeing.
  荧光增白剂荧光的产生因紫外光而来,所以照射光源的紫外光含量对荧光增白剂的荧光强度和增白效果就有影响,如果照射光中紫外光含量高,其增白效果就特别显著;而在紫外光含量低或没有紫外光的光源下,增白效果很小或根本看不出增白作用。
  The fluorescence of fluorescent whitening agent comes from ultraviolet light, so the content of ultraviolet light of irradiation source has an effect on the fluorescence intensity and whitening effect of fluorescent whitening agent. If the content of ultraviolet light is high in irradiation light, the whitening effect is particularly remarkable; but when the content of ultraviolet light is low or there is no ultraviolet light source, the whitening effect is very small or no whitening effect at all.
  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.
