A low-viscosity environment-friendly composite glue solution relates to a composition for adhesive or surface protection, a component A does not contain gamma-aminopropyltriethoxysilane, a component A and/or a component B at least comprise dodecanol ester accounting for 1-30% of the total amount of water glass, the component B comprises 32-40 parts of polyether polyol and/or polyester polyol and 24-75 parts of isocyanate, a diluent or a viscosity reducer accounts for 10-35% of the total mass, and the component B comprises 20-30% of water glass. The invention also provides a preparation method. The adhesive has the advantages of good wettability, permeability and compatibility, flame retardation, corrosion inhibition and antirust effects, normal temperature curing, low carbon, environmental protection, substantial improvement of the bonding strength, improvement of the humidity and heat resistance of the adhesive, smooth cementation body surface, few raw material types, low production cost and simple process,
