However, the ecological wood has poor waterproof and sun-proof performances, limited ecological wood resources and high processing cost, and is not suitable for large-scale outdoor decoration.
The plastic pipe and the plate are convenient to process and produce, have good plasticity and are convenient to process into architectural ornament articles with various shapes. Therefore, the plastic is used for processing the pipes and the plates with the wood grain imitation into a more economical and efficient mode. However, because of the limitation of the texture of the plastic material, how to achieve realistic appearance and texture of wood-like texture becomes a difficult point, so after the plastic pipe and plate are molded, various post-treatments are generally required to simulate the texture of wood grain, and the common methods are as follows: the method has high processing cost, needs an adhesive in the veneer and has poor environmental protection. The wood grain is also firstly polished by a polishing machine and then pressed by a knurling machine, but the mode has the disadvantages of complex operation, high processing cost, more dust generation and ecological environment pollution.
In view of this, the present invention is proposed.

In the invention, because the material of the pipe or plate fused blank 1 has contraction sensitivity when meeting water, the surface of the pipe or plate fused blank 1 can form contraction marks with different heights and depths under different cooling water circulation speeds, thereby simulating the texture of wood grains. In addition, the wood grain imitating cooling water tank 19 refers to the real wood grain color distribution during the design, and the wood grain imitating cooling water tanks 19 with different colors can be arranged according to the actual requirement, so that the contraction prints with different heights and depths are distributed on the surface of the pipe or plate melting blank 1, and the texture of the wood grain is more real and beautiful; the amount of the added toner is expressed as the shade of the color of the plate and the pipe, and the color of the toner is selected according to the product requirements.
The depth of the wood grain is mainly determined by the cooling efficiency in the setting device and the cooling water tank, and although the addition amount of the resin also affects the depth of the wood grain, if the mass ratio of the resin is not in accordance with the ratio of PPB or HDPE: CaCO 3: toner =100 parts: 2-5 parts of: if the amount of 5 parts is larger or smaller, the amount of CaCO3 is too large or too small, which affects the molding of the final product.
Meanwhile, the process of preparing the wood grain-like pipe or plate is efficient, environment-friendly and stable, and compared with the traditional wood grain-like texture post-treatment process, the production efficiency is greatly improved, the production cost is reduced, and meanwhile, the process is safe, environment-friendly and free of environment pollution.
