BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pseudo tree used as various constructions such as fences in a park, and more particularly to the construction of a pseudo tree using a metal base material such as steel.

[0002]

2. Description of the Related Art As a conventional pseudo-wood, it is generally known that a concrete or synthetic resin is used and a wood frame-like uneven surface is formed on the surface by a mold.

[0003]

However, among these conventional artificial wood, concrete artificial wood uses cement and water, so that cracks are likely to occur due to shrinkage and freezing of water at the time of manufacture, and the quality is uniform. However, there is a problem in that the workability is not good because the outer weight is large.

Further, the artificial wood made of synthetic resin has an advantage that it is light and easy to mold, but it has a problem in strength and durability, and as a material which can endure long-term use, it is currently used. However, the proper one has not been obtained.

On the other hand, in consideration of the strength of the material, there is a method of coating the surface of a metal pipe such as steel or a mold material with a paint, but in conventional metal coating, baking coating is generally used. However, there is a problem in that it cannot be easily made on-site because heat treatment with a heating pot is required at the manufacturing stage, and it is unavoidable to use factory production.

[0006]

In order to solve the problems of the above-mentioned conventional concrete, synthetic resin, and pseudo wood having a metal as a base material, the present invention may cause cracks such as concrete. In addition, the present invention aims to provide a metal-based pseudo-wood which is superior in strength and durability to synthetic resin and which can be obtained by simple processing without requiring baking coating on a metal surface. Is.

As a concrete means for that purpose, the metallic pseudo-wood of the present invention is coated with an undercoating layer of an epoxy resin-based undercoating agent and an acrylic resin-based intermediate coating control agent on the surface of a metallic base material from which oil and fat have been removed. After that, the main component is a pigment and an acrylic resin emulsion, to which water, a film-forming aid, a pigment dispersant, a defoaming agent and an antiseptic and fungicide, and a main component, silica sand, white cement, Inorganic pigment, by applying a wood grain treatment agent consisting of an extender containing a urethane resin adhesive as a component, to form a wood grain-like uneven surface before drying the wood grain treatment agent, after drying the wood grain treatment agent, the The present invention is characterized in that a urethane-based or fluorine-based resin wood-finishing coloring paint is applied to the surface of the wood-like uneven surface.
