The present invention discloses a recombinant wooden board using polyimide modified urethane adhesive and its. The present invention is a recombinant blockboard prepared by adhering and squeezing the fiber strip with an adhesive, the paint layer is provided on the surface of the recombinant blockboard, the side surface and side grooves are provided on the side of the recombinant blockboard, the adhesive 5 to 20 parts by weight of polyisocyanate, 1 to 10 parts by weight of polyacid anhydride, 30 to 50 parts by weight of polyol, 20 to 50 parts by weight of plasticizer, 0.02 to 0.20 parts by weight of catalyst, 0.5 to 3 parts by weight of antifoam, 0.02 It is prepared from a raw material which is ˜0.20 parts by weight of a dehydrating agent, 0.02 to 0.5 parts by weight of a coupling agent, and 0.02 to 0.20 parts by weight of an antioxidant. The present invention can effectively reduce the waste of wood materials, save wood resources, and have superior economic benefits. In addition, the present invention can improve the viscosity of the wooden floorboard and the connection strength between the light transmission and the floorboard. |
