The invention discloses a production method of a superfine glass wool product. The production method comprises the following steps of: recovering shattered glass, cleaning and crushing; preparing raw materials including feldspar, dolomite, sodium carbonate and borax, and testing and analyzing the components of the raw materials; calculating the use levels of the raw materials according to the required proportion of the compound in a batch mixture, and weighting and mixing the raw materials and the shattered glass to prepare the batch mixture; founding the batch mixture to obtain uniform, purified and transparent molten glass; preparing a binder; fiberizing the molten glass to obtain glass wool, and spraying the binder into the glass wool; solidifying and sizing and the glass wool; and carrying out aftertreatment on the glass wool product. In the invention, the water soluble resin binder is used so that the produced glass wool product has good elasticity and is uniform. Since the recovered waste glass is adopted as the main raw material, the recycle of resource is realized, the environment is protected, and the cost is saved. In addition, the production method of the superfine glass wool product has simple operation.
