Effect of VAE Latex Powder Addition on Tensile and Shear Properties of Styrene-Acrylate Based Cement Composite Joint Compound
2019
Abstract.In order to study the effect of VAE latex powder on the tensile and shear properties of styrene-acrylic emulsion-based cement compound joint compound (PCJS), the tensile test and shear test of PCJS under different VAE latex powder content (0~5%) were carried out. The test results show that the incorporation of VAE latex powder improves the tensile and shear mechanical properties of PCJS. When the amount of latex powder is 5%, compared with PCJS without latex powder, the shear modulus of PCJS increased by 32% and 35%; with the increase of VAE latex powder, the tensile and shear deformation properties of PCJS increased first and then decreased. When the amount of latex powder was 3%, the shear deformation performance of PCJS is the best; the incorporation of VAE latex powder has no obvious effect on the tensile elongation improvement of PCJS at break. In addition, the mechanism analysis of the effect of VAE latex powder on tensile and shear properties of PCJS was carried out.
