摘　　要：讨论了纳米SiO2、丹巴白云母、乳液对外墙乳胶漆失光率的影响。乳胶漆中加入0．1％纳米SiO2，A失光率由39％降为13％，B失光率由13％降为2％，最大降幅达85％；加入丹巴白云母5％，乳胶漆A失光率由39％降为23％，B失光率由13％降为8％，最大降幅为40％左右；乳液的性能不同，乳胶漆的失光率就不同。研究表明，纳米SiO2对降低乳胶漆失光率具有重要作用。The effects of the nano-SiO2, white mica and emulsion on me glos are discussed in this paper. Adding nano-SiO2 0. 1% to the coatings, the gloss reduction of A-coatings decreased from 39 % to 13 % and B-coatings decreased from 13 % to 2 %, the maximal extent of decrease is 85 %; adding white mica 5 % to the coatings, the gloss reduction of A-coatings decreased from 39% to 23% and B-coatings decreased from 13% to 8% ,the maximal extent of decrease is 40%; the gloss reduction of coatings was changing with the performance of the emulsion. The study shows that nano-SiO2 has important effect on decreasing the gloss reduction of coatings.
