| 摘 要： | 介绍了水性苯丙乳液涂料的配方以及改性纳米TiO2水性涂料的配制方法。通过正交实验和单因素实验确定了分散剂、偶联剂、纳米TiO2和pH的最佳用量为:m(六偏磷酸钠)=0.5 g,v(偶联剂)=1.5 mL,w(TiO2)=0.5%,pH7.8。与普通水性涂料相比,新合成的纳米涂料具有优异的物理性能,附着力达到1级,耐水性超过120 h,耐碱性超过96 h,耐擦洗性超过5 000次。

| Abstract: | The formula of waterborne styrene-acrylicemulsion coatings and preparation method of modified nano-TiO2waterborne coatings were introduced.The optimaldosages of dispersant,coupler,nano-TiO2and pH valuewere confirmed by the orthogonal test and single factors testas follows:m(sodium hexametaphosphate) 0.5 g,V(cou-pling agents) 1.5 mL,w(TiO2) 0.5% and pH of 7.8.Compared with the common waterborne coatings,the newlyprepared nano-coatings have excellent physical properties.The adhesion is up to 1 grade,water resistance more than120 h,alkalinily resistance more than 96 h and scrubresistance more than 5 000 times. |
