The invention discloses a wood environmental protection adhesive, which comprises the following raw materials by weight: 100-165 parts of sweet potato starch, 10-20 parts of pentaerythritol oleate, 9-16 parts of N,N-dimethylacetamide, 2-5 parts of sodium hydroxide, 3-7 parts of epoxy chlorobutane, 2-5 parts of urea, 0.3-0.7 part of a coupling agent, 0.1-0.4 part of an initiator, 0.1-0.3 part of a catalyst, 0.1-0.4 part of a stabilizer, 0.5-1 part of a defoamer, 0.6-1.2 parts of a plasticizer, 0.5-0.9 part of a toughening agent, and 0.4-0.8 part of a tackifier. According to the present invention, the wood environmental protection adhesive has characteristics of high strength and strong water resistance, and completely meets the related standard in GB/T14732-2006, and the strength of the produced plywood is far beyond the national class II wood-based panel standard; and the wood environmental protection adhesive can be widely used in production of wood-based panels, plywood and cellulose boards, and can replace the three aldehyde glue.
