Description

  The present invention relates to a method for decorating artificial wood.

  BACKGROUND ART Artificial artificial trees made of synthetic resin as a main raw material by imitating natural trees are known.

  As a conventional method of forming a pattern of a cut surface of a tree, particularly a pattern of an annual ring on an end face of such a pseudo tree, a method of manufacturing a pseudo tree with an annual ring described in Patent Document 1 has been known.

In the method of manufacturing a pseudo-wood with an annual ring described in Patent Document 1, as shown in FIG. 4, an annual ring cap 305 having a pattern of annual rings on its surface is inserted into a mold 304, and the annual ring cap 305 is removed. By filling the mold 304 with a molten resin in a state of being inserted into the mold 304, a pseudo wood with annual rings has been manufactured.

  However, in the conventional method of manufacturing a pseudo-wood with an annual ring, once the manufactured pseudo-wood is cut, it becomes impossible to form a pattern of the annual rings on the cut surface, which is inconvenient.

  Therefore, the present invention provides a method for decorating a pseudo-wood which can form a pattern of the cut surface of the tree on the cut surface of the cut pseudo-wood.

  In order to solve the above problems, the present invention is to heat and press a mold in which the unevenness of the pattern of the cut surface of the tree is formed on the end surface of the pseudo-wood made of a hot-melt synthetic resin as a main material, Provided is a method of decorating a pseudo-wood, comprising a step of forming unevenness of a pattern of a cut surface of a tree on an end face.

  The pseudo wood is formed using a heat-fusible synthetic resin as a main raw material.

  The reason why the heat-fusible synthetic resin is used as the main material is to form irregularities in the cut surface of the wood on the end face of the pseudo-wood by pressing the heated mold as described later.

  In the mold pressed against the end face of the artificial tree, the pattern of the cut surface of the tree is formed with irregularities.

  For example, by forming a convex portion on the mold so that the annual ring portion of the tree becomes concave, the annual ring becomes concave on the end surface of the artificial tree, and the unevenness of the pattern of the cut surface of the tree can be copied.

  Here, what kind of pattern is to be formed as the pattern of the cut surface of the tree may be appropriately selected in consideration of the design of the artificial tree.

  For example, when forming a pattern of a cut section of a tree on a columnar pseudo-tree as a pseudo-tree, it is only necessary to form the cut-away section of the tree so that the annual rings are circular. When forming a pattern of a cut surface of a tree, a circular annual ring may be used as the pattern, or a pattern of only a part of the annual ring may be used.

  In this way, by heating the mold in which the pattern of the cut surface of the tree is formed in advance and pressing it against the end surface of the pseudo tree formed of the heat-soluble synthetic resin material, the end surface of the pseudo tree is melted and formed into a mold. The concavo-convex pattern of the pattern is copied on the end face of the artificial tree with the concavity and convexity reversed.

  Here, by mixing the wood powder with the synthetic resin forming the artificial wood, not only the appearance but also the touch can be made closer to that of the natural wood.

  Further, the pseudo tree can be formed in a solid state, that is, without forming a cavity in the pseudo tree, and by cutting this solid pseudo tree, an end face for pressing the mold can be formed.

  Further, it is also possible to have a pattern forming step of forming a pattern by applying a paint to the end face of the artificial wood after the irregularities are formed by the mold.

  Since the mold is heated and pressed against a hot-melt synthetic resin, it must be formed of a material having a higher melting temperature than this resin.For example, copper, zinc alloy, aluminum, carbon steel, stainless steel and beryllium steel And at least one of metal, cement, and ceramic.

  Further, the present invention is a mold in which irregularities of a pattern of a cut surface of a tree are formed, and the mold is heated and pressed against an end surface of a pseudo-wood made of a hot-melt synthetic resin as a main raw material. Provided is a mold characterized in that unevenness of a pattern of a cut surface of a tree can be formed on an end face.

  This mold is a mold used in the above-described method of decorating a false tree, and its configuration is as described above.

  In addition, since this mold is also heated and pressed against the hot-melt synthetic resin, it is necessary to form the mold with a material having a higher melting temperature than this resin. For example, copper, zinc alloy, aluminum, carbon steel, stainless steel Or beryllium steel or the like, or at least one of cement, and ceramic.

  As described above, according to the present invention, since the pattern of the cut surface of the tree is formed by the mold, the pattern of the cut surface of the tree can be formed on the cut surface of the cut pseudo-wood.

  FIG. 1 is a schematic diagram illustrating a state in which a false tree 100 is pressed against a mold 101.

  The artificial wood 100 is obtained by mixing a plastic powder obtained by crushing a PET bottle and a polypropylene into wood powder obtained by crushing a piece of wood, which is a waste material, and then solidifying by adding a binder. The side peripheral surface 100a is provided with decoration as the artificial wood. ing.

  In the present embodiment, the wood flour, the plastic flour, and the polypropylene are blended in a ratio of 5: 3: 2 to form the pseudo wood 100, but the present invention is not limited to this. What is necessary is just to use the hot-melt synthetic resin which melts as a main raw material.

  Further, in the present embodiment, wood flour is inserted in order to make the feel closer to natural wood, but it is not always necessary to put wood flour.

  Furthermore, since the artificial tree 100 in this embodiment is formed in a solid shape without forming a cavity in the artificial tree 100, when the artificial tree 100 is cut in the width direction, the cut surface becomes a flat end face 101b.

  Here, in the present embodiment, the pseudo tree 100 has a cylindrical shape. However, the pseudo tree 100 is not limited to a cylindrical shape, and may be, for example, a triangular prism or a quadrangular prism.

  The mold 101 is made of aluminum and has a pattern of a cut surface of a tree.

  Specifically, the convex portion 102 is formed such that the annual ring portion of the cut surface of the tree is convex.

  The projections 102 serving as the pattern of the cut surface of the tree are formed such that the concave portions of the end surface 100b of the pseudo tree 100 have an annual ring pattern when the projections 102 are transferred to the end surface 100b of the pseudo tree 100.

  That is, as shown in FIG. 2, in the vertical cross-sectional view taken along line X-X ′ of the mold 101, the annual ring portion of the mold 101 is formed as a convex protrusion 102.

  In addition, the design of the convex part 102 which becomes this annual ring part, for example, the space | interval and magnitude | size of the convex part 102 which becomes a concave part when it is image | photographed on the end surface 101b of the artificial tree 100, consider the design of the entire artificial tree 100 timely. Just select.

  As described above, after heating the mold 101 on which the convex portion 102 serving as the annual ring portion is formed, by pressing the end surface 100b of the artificial tree 100 on the surface of the mold 101 on which the convex portion 102 is formed, The convex portion 102 formed on the mold 101 is copied as a concave portion on the end face 101b of the artificial tree 100, and a pattern of annual rings is formed on the artificial tree 100.

  The end surface 100b of the artificial wood 100 formed in this way can be decorated with a more textured artificial wood 100 by appropriately selecting a paint and applying the paint.

  The decoration method of the artificial tree 100 using the mold 101 described above will be described with reference to the flowchart shown in FIG.

  After mixing the plastic powder obtained by pulverizing the PET bottle and the polypropylene with the wood powder obtained by pulverizing the wood chips as the waste material, a binder is added and solidified to produce the pseudo wood 100 (S210).

  An end face 100b is formed by cutting the manufactured artificial wood 100 in the width direction (S211).

  The mold 101 is heated and pressed against the end face 100b of the dummy wood 100 (S212).

  After this, it is also possible to decorate the end face 100b of the artificial wood 100 with paint.

  In the embodiment described above, the mold 101 made of aluminum is used. However, the present invention is not limited to this. The mold 101 may be formed of a metal other than aluminum, or may be formed of cement or ceramic. 101 may be formed.
