The invention relates to the technical field of synthetic-wood production, and in particular discloses a wood-like synthetic-wood common-squeezing material and a preparation method thereof. A common synthetic-wood material has the problems of being relatively fragile in texture and easy to age, and high-density polyethylene, an ethylene acrylic acid copolymer, anti-ultraviolet master batch and surlyn resin are added to raw materials of the wood-like synthetic-wood common-squeezing material. In the preparation process, the head of a squeezer is connected with the cylinder of another squeezer, then an outer-layer material can be molten simultaneously by using the two squeezers, and the outer-layer material is squeezed to a common-squeezing mold to form an outer layer. At the same time, a third squeezer is adopted to melt a core-layer material, then a core layer can be formed by using the common-squeezing mold, and a finished product can be manufactured through procedures such as knurling and polishing. The synthetic-wood material disclosed by the invention is relatively good in tensile property, impact resistance and bending resistance and good in adhesion property of inner and outer layers. The surface of the synthetic-wood material is capable of preventing ultraviolet rays, chemical medicines and wearing, and is slow in aging speed and not liable to fade. In addition, the surface of the material can be relatively natural and vivid, and the synthetic-wood material is relatively true in wood simulation effect, and relatively good in layering.
