A wood-like composite plastic specifically used for furniture and a preparation method therefor. The method comprises firstly dispersing a nano-ceramic pigment in a saturated aluminum sulfate solution, and infiltrating micropores of a wood powder with aluminum sulfate and the nano-ceramic pigment by means of soaking the wood powder; and under the action of a sodium hydroxide alkali liquor, converting aluminum sulfate into aluminum hydroxide and then curing same, such that on the one hand, the aluminum hydroxide is fixed inside the wood powder, such that the rigidity of the wood powder is increased, and the compactness is better and is closer to the characteristics of solid wood, and on the other hand, the nano ceramic pigment is fixed in the wood powder, such that the powder removal of the pigment is effectively prevented, in particular, the pigment is tightly combined with the wood powder, the floating material does not appear in an article, and the wood-like feeling is strong. The obtained wood-like composite plastic can be directly extruded to prepare a wood-like plate, can be directly extruded to form various profiles, and can also be directly extruded and molded to form furniture panels, etc., and is convenient to use.
