DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention can be easily inserted into adjacent gaps such as various outer walls and inner walls for construction, or can be easily inserted into the groove of an edge of various tables and the like, and can be easily inserted after the insertion. TECHNICAL FIELD The present invention relates to a decorative material made of a synthetic resin such as a building material characterized by reliably preventing detachment, and a molding method thereof.

[0002]

2. Description of the Related Art In general, as a decorative material used for a building material of this kind, a material formed of rubber, vinyl chloride, or the like has been generally used. However, due to the poor weather resistance and color tone due to the scratch resistance, coloring, etc. of the decorative material, it is very expensive to perform a complicated work of polymerizing and extruding a colored tape on the outer surface or painting the surface. There are disadvantages, such as problems such as air pollution at the time of incineration in recycling by heat recovery or the like, and problems such as extremely poor insertability at the time of use.

[0003]

In these conventional decorative materials, insertion is very easy. However, after the decoration, the decorative material can easily move or detach after decoration. There is an important problem. In order to solve this problem and improve the recycling of the decorative material, a soft synthetic resin such as an olefin-based or styrene-based thermoplastic elastomer having rubber-like elasticity is used instead of rubber or vinyl chloride. However, the soft synthetic resin of this thermoplastic elastomer is
There is a point that the surface has a high frictional resistance like rubber and is easily scratched. Therefore, the synthetic resin of the protective film layer and the thin film layer, which has better scratch resistance than the soft synthetic resin of the thermoplastic elastomer, can be colored, and has a small frictional resistance, is formed on the outer surface of the surface head of the decorative material body and the press-contact piece. You have achieved your goal by using

[0004]

According to the decorative material and the method of molding the same according to the present invention, the decorative material main body has a surface head, a vertical leg, and press-contact pieces formed on both sides thereof. A soft synthetic resin of a thermoplastic elastomer such as an olefin or styrene having a JISA hardness of 90 or less is used as a constituent material of the decorative material main body. The outer surface of the surface head and the pressure contact piece is formed using a slightly hard synthetic resin such as an olefin and styrene having a JISA hardness of 95 or more, which has excellent scratch resistance and low frictional resistance. ing. In addition, as a method of molding the decorative material main body, a soft synthetic resin of a thermoplastic elastomer for molding the surface head, legs, and press-contact pieces of the decorative material main body is injected into a first extruder. A synthetic resin having a low frictional resistance laminated on the surface head and the outer surface of the pressure contact piece is made of a second resin.
Inject into the extruder. The first and second extrusion molding machines are operated, and are integrally formed by heat fusion in one die.
