涂装中油漆用的固化剂有什么作用?
固化剂也叫催干剂硬化剂,干燥剂,是一种具有催化作用的化合物,固化剂加入双组分涂料中,能与合成树脂发生交联反应形成涂膜,固化剂主要应用于不能自然干燥和烘烤成膜的涂料中
喷漆中的固化剂有什么作用?
展开3全部 油漆固化剂是专门在油漆中使用的一种材料,可以加速油漆干燥,促进油漆干燥速度。
1、物理干燥作用:油漆内部分子直接与空气中的氧气发生反映,从而达到干燥的目的。
2、化学固化作用:固化剂和主漆结合起反应,可以增加漆膜的硬度、亮度和粘合度,提高油漆的化学稳定性和防腐能力。可以使漆膜饱满细腻,光滑有弹性,耐磨不易划伤。
3、固化剂也能加速底漆和面板的上漆坚固。
4、加速底漆的固化时间、如果底漆固化时间慢,也耽误上面漆的时间。如果时间不紧急的话,有一些底漆不加固化剂,需要等底漆彻底干了之后才能上面漆。所以也浪费时间。

油漆固化剂的作用是什么?
油漆固化剂的作用是:
1、加速底漆的固化时间。
2、如果底漆固化时间慢,也耽误上面漆的时间。
3、如果时间不紧急的话,有一些底漆不加固化剂,需要等底漆彻底干了之后才能上面漆。所以也浪费时间。
4、还有固化剂也能加速底漆和面板的上漆坚固。
所以很多木器漆三合一的,都有必备固化剂的。
扩展资料:
固化剂的固化温度和固化物的耐热性有很大关系。同样地,在同一类固化剂中,虽然具有相同的官能基,但因化学结构不同,其性质和固化物特性也不同。因此,全面了解具有相同官能基而化学结构不同的多胺固化剂的性状、特点,对选择固化剂来说,是很重要的。
在色相方面,脂环族最浅,基本上是透明的,而脂肪族和芳香族,其着色程度相当显著。在黏度方面,也有很大不同,脂环族不过零点零几Pa·s,而聚酰胺则非常黏稠,达数Pa·s,芳香族胺多为固态。适用期长短正好与固化性完全相反,脂肪族反应性更高,而脂环族、酰胺、芳香族依次降低。
