This invention relates to the technical field of solid waste recycling, and discloses a method for preparing building materials based on multi-source solid waste and a high-strength insulation board. The method for preparing building materials based on multi-source solid waste includes the following steps: pretreatment of oil shale slag, pretreatment of ammonia-alkali white mud and kitchen shell waste, pretreatment of waste photovoltaic panels, pretreatment of ferrosilicon manganese slag, pretreatment of lead-zinc slag and vanadium-titanium ore slag, pretreatment of fly ash and coal gangue, pretreatment of waste aerated concrete, preparation of ultra-high performance concrete, preparation of foamed concrete, etc. The high-strength insulation board includes a polyurethane board in the middle layer, and foamed concrete board layers and ultra-high performance concrete board layers are arranged sequentially on both sides of the polyurethane board. A steel grid mesh is set between the foamed concrete board layers and the ultra-high performance concrete board layers. The foamed concrete board layers are formed by pouring the prepared foamed concrete, and the ultra-high performance concrete board layers are formed by pouring the prepared ultra-high performance concrete.
