Zusammenfassung:	The invention discloses a method for preparing an industrial sodium silicate adhesive. The method comprises the following steps of firstly preparing a sodium orthosilicate crude product, preparing solid sodium silicate, dissolving the solid sodium silicate into a special mixed solution of an adhesive and water, and then filtering to obtain a sodium silicate solution; adding sodium hydrogen sulfite to the sodium silicate solution to generate precipitated light silicon dioxide and a sodium sulfite solution, and filtering the generated mixture; concentrating and drying the other part of filtrate to obtain high-quality industrial sodium silicate; and mixing the prepared high-quality industrial sodium silicate and 2-fold resin emulsion, adding the mixed solution to silica sand, and fully mixing to obtain the sodium silicate adhesive. Main ingredients of the sodium silicate after being hardened are a silicon gel and a solid, the specific surface area is large, and the adhesive property is greatly improved. The sodi
