利用气相纳米SiO_2(二氧化硅)的活性改变了EP(环氧树脂)胶粘剂的黏度,提高了环氧基与纳米SiO_2的键合力,改善了EP胶粘剂的粘接性能。研究结果表明:当w(纳米SiO_2)=2%(相对于EP胶粘剂中基料质量而言)时,胶粘剂的剪切强度相对最大,同时兼具良好的浮辊剥离强度,并且胶粘剂的施工性能得到明显改善,克服了施工缺陷。 The viscosity of EP (epoxy resin) adhesive was changed by the activity of gas phase nano-SiO 2 (silica), the bonding force between epoxy group and nano-SiO 2 was improved, and the adhesive property of EP adhesive was improved. The results show that when w (nano-SiO_2) = 2% (relative to the mass of binder in EP binder), the shear strength of the adhesive is relative maximum, and at the same time it possesses good peel strength and the adhesive performance Obvious improvement has been achieved to overcome construction deficiencies.
