The invention discloses a modified sodium silicate binder and belongs to the field of wood binders. The modified sodium silicate binder is prepared from raw materials in parts by weight as follows: 30-40 parts of a fungus extract, 8-10 parts of agar, 80-100 parts of water, 30-40 parts of a silicone-acrylate emulsion and 160-180 parts of sodium silicate. The agar is firstly placed in water to be heated and stirred to be dissolved and mixed with the silicone-acrylate emulsion and sodium silicate after being cooled, the mixture is stirred at the high speed for 30-50 min, the fungus extract is added, the mixture is continuously stirred and mixed, reduced pressure concentration is performed, and the modified sodium silicate binder is prepared, wherein diatomite with the mass 0.03-0.04 times that of the fungus extract is also added. The modified sodium silicate binder has excellent performance and overcomes the defects that traditional sodium silicate has low bonding power and poor water resistance and is prone to dispersion.
