The invention relates to an environment-friendly two-component wood-splicing adhesive with super water resistance. The adhesive is prepared from a component A and a component B according to a weight ratio of 100: 10-18. The component A is prepared from the following raw materials by weight: 300 to 600 parts of polyvinyl acetate emulsion, 100 to 400 parts of an aqueous solution of polyvinyl alcohol, 20 to 100 parts of ethylene ethanoate-ethylene copolymer emulsion, 100 to 200 parts of heavy calcium carbonate, 50 to 100 parts of water, 4 to 6 parts of bentonite, 0.25 to 0.75 part of a plasticizer and 0.25 to 0.75 part of an antifoaming agent. The component B is polyisocyanate polymer. The wood-splicing adhesive provided by the invention overcomes the disadvantages that conventional two-component white emulsion has ordinary water resistance, is complex to prepare and is not environment-friendly; the wood-splicing adhesive has excellent resistance to water, cold, heat and solvent corrosion and is environment-friendly; and the preparation method for the wood-splicing adhesive is simple.
