摘要（英）：

A high-temperature resistant waterproof adsorption type silicate adhesive and a preparation method thereof are provided. That silicate adhesive is prepared from the following reaction raw materials: aliquid-phase silicate mixture, a curing agent and an inorganic toughening filler; wherein the liquid-phase silicate mixture is a mixed solution of a potassium silicate solution and a lithium silicatesolution; the curing agent is prepared from a reaction raw material including aluminum hydroxide and phosphoric acid; the silicate adhesive comprises the following raw materials in percentage by weight: 30-35% of liquid-phase silicate mixture, 2-3% of aluminum hydroxide, 8-12% of solute in phosphoric acid solution and 43-60% of inorganic toughen filler, based on that total weight of the liquid-phase silicate mixture, the aluminum hydroxide, the solute in phosphoric acid solution and the inorganic toughen filler being 100%, wherein the liquid-phase silicate mixture is a mixed solution of a potassium silicate solution and a lithium silicate solution. A silicate adhesive obtained by that invention can realize better water-resistant molecular adsorption and insulation performance in a high-temperature and humid environment.
