Summary:The invention discloses a magnesium oxysulfate cementing composite material for a prefabricated thermal insulation wallboard and a preparation method. The magnesium oxysulfate cementing composite material is prepared from, by weight, 10-20 parts of magnesium sulfate heptahydrate, 50-65 parts of water, 80-100 parts of light calcined magnesia, 2-15 parts of powdered filler, 1-10 parts of fibrous filler and 1-5 parts of compound modifier. The preparation method of the composite material comprises the steps that magnesium sulfate heptahydrate is prepared into an aqueous solution, light calcined magnesia and the powdered filler are added, stirring is conducted for 5 min, the compound modifier and the fibrous filler are added, stirring is continuously conducted for 10 min to 30 min, an obtained magnesium oxysulfate cementing material slurry is added into a mold paved with a non-woven cloth and a fiberglass mesh cloth, and curing molding is conducted. The prefabricated thermal insulation wallboard produced through t
