摘要：

Acrylic resin/nano-SiO2 (AR/nano-SiO2) composite was prepared by physical blends of acrylic resin (AR) and nano-SiO2, which was synthesized via the sol-gel method of tetraethoxysilane (TEOS) catalyzed with alkali. The synthetic conditions, such as surfactant type, the content of nano-SiO2 sol, stirring speed, mixed temperature and ultrasonic treatment, on nanocomposites' property were studied in detail. DSC indicated the glass transition temperature of AR/nano-SiO2 (Tg = -26.7 degrees C) was a little higher than that of the acrylic resin (Tg= -29.6 degrees C). Water uptake confirmed that the water resistance of AR/nano-SiO2 was improved by 55.94% and the solvent resistance by 54.79% when compared with AR. The improved properties of leather finished by AR/nano-SiO2 were shown, in contrast to AR treatment; water vapor permeability was increased by 9.15% and the finish adhesion by 10.35%.
