摘要: Influence of expandable graphite on flame retardancy and mechanical properties organic–inorganic hybrid material based sodium silicate polyisocyanate has been investigated. The results measurement show that adding decreases the maximum compressive strength from 5.98 to 1.49 MPa. thermal property is evaluated by conductivity test, thermogravimetric analysis. indicate increases composite lowers heat release rate. with better than original an obvious decrease in rate, fire spread decomposition What more, intumescent effect suppress prevent fire. Scanning electron microscope shows many large particles gaps appear after compression deformation.
