The invention relates to the technical field of polyvinyl chloride resin and in particular to a nanoparticle latex and nanoparticle enhanced and toughened vinyl chloride composite resin and a preparation method thereof. The nanoparticle latex is prepared by the following steps: dissolving acrylate in a crosslinking agent to form a mixed liquid of acrylate and the crosslinking agent; and then by taking deionized water as a solvent, adding an active nanoparticle nucleating agent, an emulsifying agent, an initiator I and a pH value adjustor into the solvent. The preparation method of producing nanoparticle latex is lower, short in synthetic time, simple and easy to control and high in production efficiency; nanoparticles can achieve a dispersing action of nanoscale. By adopting the nanoparticle latex, the nanoparticle enhanced and toughened polyvinyl chloride composite resin which has an interpenetrating coating structure and is better in toughness can be prepared. The nanoparticle enhanced and toughened vinyl c
