Embodiment Construction
[0009] 1. Specific formula
[0010] Shell: straw powder 50%, light mineral powder 35%, fly ash 2.9%, halogen powder 10%, glass fiber silk 1%, gelling agent 0.5%, flame retardant 0.5%, brightener 0.05%, curing agent 0.05%,
[0011] Inner core: polystyrene foam, thickness 80mm.
[0012] 2. Manufacturing method
[0013] Match the required raw material ingredients in proportion-uniformly stir-inject into the mold-level-spread glass fiber-inject the mixed raw material for the second time-second level-place the polystyrene with a length of 2600mm×250mm×80mm Two vinyl foam boards with a 10mm gap between them-the third injection of mixed raw materials-the second time of laying glass filaments-the fourth injection-leveling (the entire operation process is completed within 20 minutes) —— Curing—— Demoulding—— Natural curing, after drying, it can be used in the factory.
