用A-151和KH-570对纳米SiO2进行改性，并与丙烯酸酯单体反应制备得到复合乳液。用傅里叶红外光谱仪对改性硅溶胶进行了检测，测定了复合乳液的密度和黏度。加固过的土块耐水能力和抗压能力提高了2倍，并且抗盐碱和抗冻融能力有明显的提高。改性纳米SiO2/聚丙烯酸酯复合乳液可以应用于土遗址保护。
用A-151和KH-570對納米SiO2進行改性，併與丙烯痠酯單體反應製備得到複閤乳液。用傅裏葉紅外光譜儀對改性硅溶膠進行瞭檢測，測定瞭複閤乳液的密度和黏度。加固過的土塊耐水能力和抗壓能力提高瞭2倍，併且抗鹽堿和抗凍融能力有明顯的提高。改性納米SiO2/聚丙烯痠酯複閤乳液可以應用于土遺阯保護。

Silane eoupling agent A-151 and KH-570 were used for hydrophobie modifieation of siliea sol. Composite latex was prepared with modified silieon sol and aerylate. The modified silieon sol were analy-sised and eharaeterized by FTIR. The density and viseosity were measured by viseosimeter and surfaee tensiometer. Reinforeed elod ’s water resistant ability and eompressive ability were improved twiee,and it’s salt resistanee and freeze resistanee were inereased signifieantly. Modified nano-SiO2/polyaerylate eomposite emulsion ean be used in the ruins of soil proteetion.
