一种低温固化的粉末涂料及其制备方法
摘要：
本发明公开了一种低温固化的粉末涂料，包括组分A和组分B；所述组分A包括环氧树脂、流平剂、脱气剂、抗氧剂、光亮剂、分散助剂、流平助剂、催化剂、增硬剂；所述组分B包括脂肪族胺类固化剂、流平剂、脱气剂、抗氧剂、光亮剂、分散助剂、流平助剂、催化剂、增硬剂。相比于油漆以及水性涂料，本发明所述粉末涂料不含VOC，以及接近100％的涂料利用率；与现有技术中的粉末涂料相比，本发明所述粉末涂料将固化温度从180℃以上降低到小于等于130℃，减少了涂层固化过程由于加热对工件，如木材造成的损伤，且涂装效率高；另外，本发明所述粉末涂料具有较好的透明性、耐化学性和装饰性能。
摘要（英）：

The invention discloses a low temperature curing powder coating. The low temperature curing powder coating comprises a component A and a component B, wherein the component A comprises epoxy resin, a leveling agent, a degassing agent, an antioxidant, a brightener, a dispersing aid, a leveling aid, a catalyst and a hardening agent; the component B comprises an aliphatic amine curing agent, a leveling agent, a degassing agent, an antioxidant, a brightener, a dispersing aid, a leveling aid, a catalyst and a hardening agent. Compared with paint and water-based coatings, the powder coating containsno VOC and has a coating utilization rate close to 100%; compared with a powder coating in the prior art, the powder coating reduces the curing temperature from 180 DEG C or above to 130 DEG C or below, thereby reducing damage of heating in a coating curing process to workpieces such as wood, and the coating efficiency is high; in addition, the powder coating has better transparency, chemical resistance and decorative performance.
