The invention discloses a high-efficiency flame-retardant, heat-insulating, expandable polystyrene and graphite composite material, comprising the following raw materials in parts by weight: 70-100 parts of styrene, 150-240 parts of desalinated water, and 5-7.6 parts of a foaming agent , 0.2-0.7 part of initiator, 0.1-0.5 part of nucleating agent, 0.5-4.5 part of flame retardant, 0.01-0.08 part of inorganic sodium salt, 0.01-3 part of graphite, 0.05-0.2 part of inorganic suspending agent, 0.0001 part of organic suspending agent ~0.0005 part, 0.001-0.005 part of dispersant, 0.01-2 part of inorganic additive, 0.001-0.005 part of pH regulator, and 0.003-0.005 part of bead distribution regulator. The product obtained by the invention has fewer powder particles, and the combustion performance fully meets the requirements of Class B in "Classification of Combustion Performance of Building Materials and Products", and has good flame retardant and fire performance and thermal insulation performance; and ensure the flame retardant and thermal insulation performance. At the same time, it has excellent mechanical properties. |
