摘要:开发了ZH一01水性双组分氟碳树脂及双组分水性氟碳涂料。研究了交联剂己二酸二酰肼(ADH)的用量对乳液凝胶率和涂膜硬度的影响,确定m(氟乳液)/m(ADH)=100:0.8。比较了ZH-01氟乳液及其相应涂料涂膜与其他市售乳液及其涂料涂膜的性能。结果表明,ZH-01氟乳液具有优良的性能,所得氟涂料涂膜比其他乳液涂料涂膜具有更好的综合特性,在抗紫外老化方面尤为突出。 关键词:氟碳涂料;水性;乳液;耐候性 中图分类号:TQ630.7 文献标志码:A 文章编号:1004—227X(2009)02—0053—03 Highly weather resistant double—component waterborne fluorocarbon coatings//WU Yu-peng*.PAN De-jun Abstract:WaterboFne double-component fluorocarbon resin ZH-01and double-component waterborne fluoro.carbon coating materials were developed.The effect of the dosage of curing agent ADH(adipic dihydrazide)on gelling rate of emulsion and coating hardness was studied.A mass ratio of fluorine.containing emulsion to ADH was determined as l 00:0.8.The performances were compared between ZH-01 fluorine.containing emulsion and the coating thereof and other emulsions available on the market and their coatings.The results showed that the ZH-01 fluorine. containing emulsion has excellent properties and the fluorocarbon coating has beRer comprehensive performances than other coatings,especially in respect of the anti- ultraviolet aging.
