The invention relates to a PVC (polyvinyl chloride) plastic building template which comprises raw materials as follows: PVC, foaming agents, foaming regulators, wetting agents, plasticizers, stabilizers, lubricating agents, anti-impact modifiers, processing auxiliaries, reinforced fiber, hollowed glass beads, hollowed ceramic micro powder, titanium dioxide, modified resin, filling agents and the like, wherein PVC can consist of a brand new PVC material and a PVC recovered material; and the modified resin can be at least one of PP (polypropylene) and PE (polyethylene) plastic particles. The hollowed ceramic micro powder with a small particle size and the hollowed glass beads with large particle sizes are mixed for use, the flatness of the surface of the building template is remarkably improved, the secondary plastering engineering is omitted, the demolding effect is good, the mounting is convenient, time and labor are saved, and the density of the building template is not remarkably increased; the heat absorptivity of the building template is reduced and the heat resistance of the building template is improved from the angle of color design; and even if the raw materials are doped with the PVC recovered material, a light-color building template even a white building template with less heat absorption can be manufactured.
