Research on the properties of nanoparticles modified sodium silicate adhesive Xin-li Zhang1, a, Yi-qiang Wu1,b* and Yun-chu Hu1,c 1School of Materials Science and Engineering, Central South University of Forestry and Technology, Changsha, P.R.
Usually said silicate adhesive mainly refers to the reactive adhesive, which generally consists of the main binders, curing agents and skeleton materials.
Adhesive structure was analyzed to show interaction between Na2SiO3 and nano-materials, and the cured morphology and thermal properties were determined to support the quality improvement of Na2SiO3 adhesive by adding nano-materials.
Materials and Methods Materials. 3.0 modulus Na2SiO3 solutions were obtained from Shangyu Qiangsheng Chemical Co., Ltd.

With continuous deformation of composite materials, debonding particles increased, thus resulting in material soften.
The results showed that the mechanical properties of materials are greatly influenced by introducing voids.
Continuous deformation of composite materials, the debonding of the particles increases, which causes softening of the material.
