【摘要】 为了制备纳米CaCO3复合建筑涂料 ,采用正交试验法优化出了纳米CaCO3表面改性的最佳操作工艺条件 :改性剂为JN 3 6、其用量为 1 5 % (质量分数 )、乳化温度为 60℃、乳化时间为 60min和保温时间为 45min。优化条件下制得的纳米CaCO3浆的稳定性好 ,四周内外观、黏度和细度均无变化。用该浆液制成的纳米复合涂料 ,与传统建筑涂料相比 ,其耐水性、耐洗刷性、耐光性、耐沾污性和贮存稳定性等显著改善。更多还原

【Abstract】 In order to prepare nano CaCO 3 composite architectural coatings,the optimum technological conditions are obtained with orthogonal experimental method,which are as follows:modifier is JN 36 and its dosage is 1 5% of nano CaCO 3,emulsifying temperature is 60℃,emulsifying time is 60min and constant temperature time is 45min. The results show that the storage stability of suspension of nano CaCO 3 is good and its appearance,viscosity and fineness are unchanged in four weeks.Compared with traditional architectural coatings, the properties of nano CaCO 3 composite coatings are improved obviously,which comprise water resistance,scrub resistance,light resistance,dirt resistance and storage stability et al.更多还原
