Provided are an additive of a urea-formaldehyde resin adhesive for an artificial board and a preparation method of the adhesive. The additive is prepared from, by weight, 50-70 parts of sepiolite powder, 100 parts of carboxymethyl sweet potato residues, 20-40 parts of cassava residues, corncob residues and 5-20 parts of oat waste; the raw materials are mixed to be uniform according to the above-mentioned proportions, and a urea-formaldehyde resin additive is obtained; the urea-formaldehyde resin additive and urea-formaldehyde resin are mixed to be uniform according to the weight part ratio of (20-30):100, and the urea-formaldehyde resin adhesive is obtained. According to the additive of the urea-formaldehyde resin adhesive for the artificial board and the preparation method of the adhesive, the preparation method is simple, the additive and the urea-formaldehyde resin adhesive have good miscibility, a good prepressing property can be given to the urea-formaldehyde resin, and the production efficiency of plywo
