Raw materials of resin adhesive for sympodial bamboo integrated profile and preparation method of resin adhesive

The invention discloses raw materials of a resin adhesive for a sympodial bamboo integrated profile and a preparation method of the resin adhesive. The raw materials include formaldehyde, phenol, anhydrous sodium sulfate, urea, oleic acid, colophony powder and water. The raw materials are characterized by further including propylene glycol, caustic soda liquid or caustic soda flakes. The preparation method is performed with the raw materials. The resin adhesive is applied to the sympodial bamboo integrated profile; the strength of the adhesively bonded bamboo profile completely meets the requirement on strength of a structural material; the prepared sympodial bamboo integrated profile is difficult to crack and deform, high in weather resistance, low in dipping and delamination rate, tight in adhering, difficult to absorb water, small in expansion coefficient, and difficult to mildew.
