摘　　要：采用共混法，将分散后的复合纳米ZnO-CeO2粉体掺杂到水性外墙涂料中，考察不同添加量的纳米颗粒对其紫外吸收抗老化能力的影响。结果表明，当改性纳米占浆料的质量百分比为1%～1.5%时，其紫外吸收抗老化能力最佳，改性涂料的耐水性、耐碱性、耐洗刷性和耐人工气候老化性都明显高于国标中优等品的技术要求。By blending method,the comPosite nano-ZnO-CeO2 doPed Powder disPersed into an aqueous exterior Paint,effects of different amounts of nanoParticles added to its anti-aging ability was investigated. UV-visible sPectroPhotometer,UV lamP Performance testing of samPles and insPection in accordance with the national standard of other Performance indicators. The results show that when the Percentage of modi-fied nano-quality PulP accounted for 1% ～1. 5%,its anti-aging ability UV absorPtion is best,modified coatings water resistance,alkali resistance,abrasion resistance and resistance to artificial weathering re-sistance technical requirements are significantly higher than the national standard in suPerior Product.
