The invention belongs to the technical field of high-molecular polymers, and particularly relates to a polyvinyl chloride composite material as well as a preparation method and application thereof. The polyvinyl chloride composite material provided by the invention comprises 100 parts of polyvinyl chloride, 2-6 parts of a heat stabilizer, 35-45 parts of a plasticizer, 1-4 parts of a lubricant, 0.5-2 parts of a light stabilizer and 0-20 parts of a nano inorganic additive, the heat stabilizer is stearate; the nano inorganic additive comprises calcium carbonate and/or talcum powder. According to the polyvinyl chloride composite material provided by the invention, polyvinyl chloride is modified by a heat stabilizer, a plasticizer, a lubricant, a light stabilizer and a nano inorganic additive together, the nano inorganic additive comprises calcium carbonate and/or talcum powder, and the heat stabilizer is stearate; meanwhile, within the range of the mass parts, the toughness and the impact strength of the polyviny
