Surfactants-styrene butadiene latex synergistic enhancement of bamboo scraps/magnesium oxychloride light composite interface compatibility

Combining bamboo processing residues with lightweight magnesium oxychlorides can produce new composite building materials that increase the utilization rate of bamboo and also improve the performance of lightweight magnesium oxychlorides. However, the incompatible interface between the two materials leads to the poor performance of the resulting composites, which limits their application in construction engineering. In this paper, a synergistic effect between surfactants and styrene-butadiene latex was used to enhance the interfacial compatibility between bamboo scraps and lightweight magnesium oxychlorides. The structure formed between the two acted as a "bridge" that enhanced the cross-linking between bamboo scraps and lightweight magnesium oxychloride, thus forming a more stable bamboo fiber-lightweight magnesium oxychloride network. The lightweight composite material obtained in this paper showed a maximum compressive stress of 6.5 MPa and a softening coefficient of 0.75.It shows great development potential in the application of light weight, high strength and water resistance building decoration materials.
