A thermal insulating wall body material is prepared from: active magnesium oxide and carbon chloride solution as binding agent; ferrous sulfate, sodium phosphate and oxalic acid as assistant agent; saw dust and broken rice husks as fillers; glass fibers or fabrics as reinforcing agent; and polystyrene plates as thermal insulating agent. Its preparation includes: preparing moulds; mixing and stirring binding agent, assistant agent, fillers, and reinforcing agent to form a paste; laying plastic film on a table and laying moulds on it; spreading the said paste in the moulds, laying glass fabrics on the paste, spreading the said paste on the fabrics, laying polystyrene plates on the paste, spreading the paste on the plates, pressing and leveling, laying glass fabrics, spreading the paste again, curing and demolding. The products have some advantages such as: high thermal insulation ability and strength; good bending rigidity, toughness, shock and deformation resistances; lightweight; easy transportation ...
