一种陶瓷基材用氟碳铝粉涂料及其制备方法

A Ceramic Substrate with Fluorocarbon Aluminium Powder Coating and Its Preparation Method

研发了一种陶瓷基材用氟碳铝粉涂料,包括底漆、面漆和清漆,其中：底漆由以下质量分数的原料制成：PVDF氟碳树脂10%~20%,丙烯酸树脂7%~10%,填料15%~20%,溶剂45%~55%,助剂3%~5%;面漆由以下质量分数的原料制成：PVDF氟碳树脂20%~25%,丙烯酸树脂10%~15%,颜料5%~15%,铝粉3%~5%,溶剂50~60%;清漆由以下质量分数的原料制成：PVDF氟碳树脂30%~40%、丙烯酸树脂10%~20%、溶剂50%~60%。其能在陶瓷基材上形成高耐候性金属效果涂层,丰富陶瓷表面装饰效果,还可降低陶瓷釉面烧制能耗。

A ceramic substrate with fluorocarbon aluminium powder coating was developed, which including primer, topcoat and varnish. The primer was prepared by PVDF fluorocarbon resin（10%~20%）, acrylic resin（7% ~ 10%）, pigment（15% ~ 20%）, solvent（45% ~ 55%） and additive（3% ~ 5%）. The topcoat was prepared by PVDF fluorocarbon resin（20% ~ 25%）, acrylic resin（10% ~ 15%）, pigment（5% ~ 15%）, aluminium（3% ~ 5%）and solvent（50% ~ 60%）. The vanish was prepared by PVDF fluorocarbon resin（30% ~ 40%）, acrylic resin（10% ~ 20%） and solvent（50% ~ 60%）. It can form high weather ability metal effect on ceramic substrate coating, rich ceramic surface adornment effect; can reduce energy consumption of ceramic glaze firing.
