Description of the Invention: [Technical Field] The present invention relates to a thermoplastic elastomer composition (TPE) for preparing a wood-like material and a method for producing a wood-like material using the composition, in particular, a utilization The thermoplastic elastomer is a substrate, and a method of producing a wood-like material using the composition without adding wood powder to produce a wood-based wood grain and a water-repellent and recyclable characteristic wood-like material. [Prior Art] Wood has always been the basic material for making furniture, guardrails, paper, certain stationery or toys. 'But in recent years, under the massive cutting of trees, 'there is no relative planting plan, and the impact of climate change, As a result, the number of trees is becoming less and less, which in turn results in a very limited amount of wood that can be used for the above purposes, especially the large perennial tree species that can be used to make large furniture. In recent years, the wood used in the home decoration mostly uses three plywood to replace the original wood. The three plywood is cut into thin slices by trees, and the glue is used to form a layer of straight lines and layers of horizontal stripes. Light and maintainable characteristics, but because the wood has the characteristics of easy to absorb water and attract termites and surnames, it is often used: during construction, waterproofing agent or anti-seize material is used to extend the service life of the three plywood. The use of water repellent not only lengthens the construction time, but also has an unpleasant odor. In addition, the strength of the three plywood is far less than the limit of the strength of the log. In order to overcome the wood moisture, corruption and breeding, some R&D personnel will plasticize the raw materials and wood 'synthesis 201024081 imitation wood building materials', the imitation wood building materials and the right paste several * one has the characteristics of plasticized materials, also The combination of the grain, so it became the new construction of the aunts, the wood of the wood mixed with wood and plastic, so when the loss of η is also caused by the smashing of the sputum, and can not be re-used and used also caused part Environmental troubles.曰 “At present, thermoplastic elastomer materials are more common in buffers in everyday life, but the buffers are mostly flexible and bendable soft materials.” To strengthen the hardness and enhance its impact resistance, it is converted into decoration. For other purposes, it is often limited by the material side, the foaming is not easy, and the molding conditions are difficult to grasp, and the technical bottle of the water is not limited, and the field of application thereof is limited. We are committed to the development of home-based environmental products and the global environment, and we hope that we can invest in the research and development of our research and development work on polymer materials for decades, and finally develop the method for preparing wood-like materials of the present invention. The main purpose of the present invention The invention provides a thermoplastic elastomer composition for preparing a wood-like material, and the wood-like material prepared by using the composition has a natural wood-grain road.

In the preparation method of the present invention, 'the gas generated during the foaming process can be covered by adding a small amount of the rack during the foaming process, and at the same time, the fluidity of the molecules inside the sheet during the foaming process is maintained. Features. Φ In the preparation method of this month, the addition amount of the foaming agent can control the pore size and density of the wood-like material after foaming, and has a great influence on the physical properties of the wood-like material as a whole. In the step of preparing the wood-like material by using the thermoplastic elastomer composition in the present invention, when the sheet is laminated and subjected to hot-press foaming and leveling, the layer may be layered due to the interaction between the four sheets. The deep and light color gradually resembles the wood grain, and the grain of the imitation wood grain may also differ depending on the thickness, color and the like of the sheet, and may be further adjusted according to circumstances. Φ [Embodiment] The thermoplastic elastomer composition for preparing a wood-like material according to the present invention, wherein the composition of the oxime correction composition comprises a thermoplastic elastomer material in a content ratio of 10 to 80% by weight, and the content ratio is 10-80% by weight.
