摘要
在前期研究成果基础上,利用JMP统计软件进行实验设计,对输出的24组配方样本的性能进行对比分析。以耐洗刷性、铅笔硬度、附着力和对比率的综合性能提升及稳定为目标,得出最佳配方为:每500 g涂料中含150 g陶瓷抛光废渣微粉(500目)、0.4 g阴离子型表面活性剂5040、150 g苯丙乳液(巴德富899)和8 g醇酯十二。此时漆膜的耐洗刷次数可以达到105 528次,比优化前提升了20 000多次,且对比率有所增大,涂料的整体性能从一等品提升为优等品。扫描电镜观察表明涂膜表面平整,经过洗刷破坏后断面形成撕裂的纤维状膜条,内部结构致密。该涂料在为期12个月的实际墙体应用中效果良好。
On the basis of the previous research results, the JMP statistical software was used for experimental design, and the properties of 24 groups of paint samples with different compositions were compared with the goals of improving and stabilizing the washability, pencil hardness, adhesion, and contrast ratio. The optimal paint composition was determined as follows: every 500 g of the paint contains ceramic polishing waste powder(500 mesh in size) 150 g, 5040-type anionic surfactant 0.4 g, Badfu 899 styrene–acrylic emulsion 150 g, and alcohol ester-12 8 g. The coating obtained therefrom endured 105 528 times of washing, which was more than 20 000 times more than that prepared before optimization, and had an enhanced contrast ratio. Based on its overall performance, the paint could be graded as a superior product after optimization,while it was a first-class product previously. The observation through scanning electron microscope showed that the surface of the coating was leveled, its section was torn to form fibrous strips after being washed, and its internal structure was compact.The application of the coating to some actual walls was satisfactory within 12 months.
