The invention relates to a method for continuously generating fine gutta-percha through digestion-reextraction. The method comprises the steps of: firstly, pre-treating folium cortex eucommiae including drying, crashing and cutting; secondly, digesting gutta-percha from folium cortex eucommiae through leach liquor; thirdly, separating gutta-percha from folium cortex resin through reextraction solution and dissolving the gutta-percha; and fourthly, post-treating materials, principally to dry the dissolved gutta-percha so as to obtain the fine gutta-percha. The method of the invention has the advantages that the leach liquor is nonflammable non-toxic agent, the gutta-percha extraction efficiency is high, the environment is prevented from being polluted, the folium cortex eucommiae is complexly used, no waste generates, the solvent is recycled, the consumption is low, the product quality is high, industrial continuous production is realized, the economic, environment-friendly and social benefits are all better than the traditional production method, and the promotional value is high.
