摘　　要：本文通过活化一复合两步法制备碳酸钙基复合白色颜料粉体。研究了不同表面改性剂对颜料性能的影响，并且测试了复合粉体的遮盖力、吸油值、白度等性能及微观形貌。结果表明选取三乙醇胺为改性剂时，复合粉体的综合性能最佳，其中遮盖力为19．5g／m2，吸油值24．2g／100g，白度95．8％。The calcium carbonate/TiO2 composite white pigment was preparcu by modifiers were used to modify the properties of the white pigments. The properties of the hiding power, oil absorption value, whiteness and microscopic morphology were tested to investigate the iMPact of different surface modifiers on the white pig- ment properties. It was found that the triethanolamine was a good surface modifier for the composite. The hiding power had reached 19.5g/m2 , the oil absorption value had reached 24. 2g/100g, and the whiteness was 95.8%.
