保定消光粉厂

消光粉和消光剂都能起到使目标材料消除光泽的作用，但一个“粉”一个“剂”，它们有着哪些区别？

Both matting powder and matting agent can eliminate the luster of the target material, but what are the differences between a "powder" and a "agent"?

 

 

消光粉是一种易分散的化学粉末，是涂料助剂的一种。常见的消光粉包括白炭黑、滑石粉。消光粉具有“直接涂抹”的特点，使用方法简单。原材料也易于得到。

Matting powder is a kind of easily dispersed chemical powder. It is a kind of paint auxiliaries. Common matting powders include silica and talcum powder. Matting powder has the characteristics of "direct smearing", and its use is simple. Raw materials are also easy to get.

 

 

消光剂则是带有环氧基的消光树脂材料。也属于涂料助剂的一种。常见的消光剂包括纯聚酯消光树脂、纯聚酯消光剂、有机消光剂、白炭黑消光剂。消光剂通过其极细微的悬浮物分散于涂料之中，涂料成膜后这些悬浮物会分散于涂膜表面，增加了涂膜粗糙度而起到降低涂膜反光度的作用。消光剂的主要品种包括金属皂、蜡、硅藻土、合成二氧化硅等。

Matting agents are epoxy resin based matting resins. It also belongs to a kind of coating auxiliaries. Common matting agents include pure polyester matting resin, pure polyester matting agent, organic matting agent, silica matting agent. The matting agent is dispersed in the coating through its very fine suspended substances. These suspended substances will disperse on the surface of the coating after the coating is formed, which increases the roughness of the coating and reduces the reflectivity of the coating. The main varieties of matting agents include metal soap, wax, diatomite and synthetic silica.

 

 

消光粉的消光机理是：通过添加有消光作用的填料，如滑石粉、超细二氧化硅等填料使涂膜光泽度降低；通过添加热塑性树脂如醋酸纤维素、聚丙烯树脂等使涂膜光泽度下降；

The extinction mechanism of the extinction powder is that the glossiness of the coating film is reduced by adding extinction fillers such as talc powder and ultrafine silica, and the glossiness of the coating film is decreased by adding thermoplastic resins such as cellulose acetate and polypropylene resin.

 

 

消光剂的消光机理则是：通过消光剂粒子广泛分散于涂膜表面，当紫外光线照射在涂膜粗糙表面时，将形成光线散射，粗糙度越大，光线越散射，从而实现哑光或不反光的消光效果。

The extinction mechanism of the extinction agent is that the particles of the extinction agent are widely dispersed on the surface of the coating. When the ultraviolet ray irradiates the rough surface of the coating, the light scatters. The larger the roughness, the more scattered the light, thus achieving the extinction effect of dumb light or non-reflective light.

 

 

消光粉中的金属皂其实是人们较常用到的一种消光剂。金属皂与涂料成分不相容，而能以细小的颗粒悬浮于涂料中，成膜后发布在涂膜表面，这里可以看出，效果粉与消光剂在一定程度上是概念重合的，它们的基本消光原理和基本功效是一样的。比如硅藻土、高岭土、白炭黑等都是专门用于涂料消光的功能性消光粉，它们使用原理都是会在涂膜表面悬浮，留下粗糙的凹凸表面以形成散射光线。这些因素也是消光剂的基本因素。

The metal soap in matting powder is actually a kind of matting agent commonly used by people. Metal soap is incompatible with the composition of the paint, but can be suspended in the paint with fine particles, after the film is distributed on the surface of the film, we can see that the effect powder and matting agent to a certain extent is the concept of coincidence, their basic matting principle and basic efficacy is the same. For example, diatomite, kaolin and silica are all functional extinction powders specially used for extinction of coatings. They are used by suspending on the surface of the coatings, leaving a rough concave and convex surface to form scattered light. These factors are also the basic factors of matting agent.
