This invention discloses a method for preparing a fluorine-free heating and insulating riser, relating to the field of casting technology. The method includes first modifying micron-nano composite aluminum powder with a silane coupling agent, then in-situ reducing and loading zero-valent iron-cerium dioxide catalytic sites, followed by sequentially coating with phenolic resin and a potassium nitrate-manganese dioxide composite oxygen source, and finally forming a silica shell through interfacial hydrolysis and condensation to obtain a core-shell structured composite heating agent. Separately, hollow aluminosilicate microspheres are etched to create pores, then vacuum-impregnated and filled with an organic-inorganic composite aerogel, followed by hydrophobic modification and coating with nano-alumina sol to obtain a composite insulating material. The heating agent is then mixed with the insulating material, mullite powder, corundum powder, expandable graphite, waste glass powder, and a binder, and the mixture is vibrated, compacted, and allowed to cure to obtain the finished product. This invention solves the problems of difficult heating and poor insulation in fluorine-free risers by constructing a multi-level core-shell heating structure and a porous, multi-level insulating structure.
