Abstract

A method for manufacturing an artificial woodwork comprises forming an irregular crevice shape and node by heating the material surface of a plasticized rigid vinyl chloride with a flame of at lenst 600≰C , coating the surface with a black lacquer. The woodwork has a good natural and classical beauty.

Description

표면에 불규칙 균열모양과 옹이를 형성하는 인조목재 제조방법Manufacturing method of artificial wood which forms irregular cracks and knots on the surface

본 발명은 내부 가소화된 경질염화 비닐을 소재로 하여 표면에 불규칙 균열상과 옹이가 형성된 대용목재의 제조방법에 관한 것이다.The present invention relates to a method for producing a substitute wood in which irregular cracks and knots are formed on a surface of an internal plasticized hard vinyl chloride.

종래에도 합성수지 폐설을 이용한 대용목제가 있으나, 표면 처리에 있어서 자연목재의 모양을 나타낼 수 없었고, 시멘트 콘크리트로 외관상 자연목재와 형상과 모양을 형성하여 된 대용목재도 있으나, 대형이고 조잡하고 주로 대형 축조물에 사용된 것으로서 섬세하고 소품인 장식용으로서 적합하지 못하였다.Conventionally, there is a substitute wood using synthetic resin waste snow, but the surface of natural wood could not be expressed in the surface treatment, and there is also a substitute wood formed with the shape and shape of natural wood in appearance with cement concrete, but it is large, coarse, and mainly large scale buildings It was not used as a delicate and prop decoration as used in.

본 발명은 이와같은 문제점을 해소하기 위하여 창안한 것으로서 이하 상세히 설명하면 다음과 같다.The present invention is invented to solve such a problem and will be described in detail below.

내부 가소화된 경질염화 비닐의 원통상 또는 판상의 소재표면을 600℃이상의 국부적인 고온급열의 화염으로 가열하여 태워서 불규칙 균열상과 이면을 압압하여 옹이를 형성하고, 표면에 검정색 락카를 분사 도포한후 사포(砂抱)질하여 대용목재를 얻게된다.Cylindrical or plate-like material surface of plasticized hard vinyl chloride inside is heated and burned with a localized high temperature flame of 600 ℃ or higher to press the irregular cracks and the back surface to form knots and spray black lacquer onto the surface. After sanding (砂 抱) to obtain a substitute wood.

본 발명에 있어서 경질염과 비닐을 사용하는 이유는 가열하면 80℃에서 비결정질 부분의 염계분자 Segment가 마크로 브라운 운동을 일으켜서 분자간격이 넓어지며, 분자력이 약해져서 연화되어 인장강도 및 경도가 약해짐으로서 신장 및 탄성이 좋아지며, 또한 150℃를 넘으면 결정질 부분의 분자간격이 극히 극소화되어 균열현상이 일어나기 시작하며, 계속 가열하여, 표면을 그을리게 하는 것이다. 또한 소재가 내부가소화되어 있어 가공성이 양호하므로 가열에 의하여 연화된 상태에서 이면에서 외부로 압압하여 소정의 위치에서 소망의 형상의 옹이를 팽출형성케 할 수 있다.The reason for using hard salt and vinyl in the present invention is that when heated, the salt-based molecular segment of the amorphous portion at 80 ° C. causes macro brown movement, thereby widening the molecular interval, and weakening the molecular force, thereby softening the tensile strength and hardness. And the elasticity is improved, and if it exceeds 150 ° C, the molecular spacing of the crystalline portion is extremely minimized and cracking starts to occur, and the heating is continued to burn the surface. In addition, since the raw material is plasticized inside and the workability is good, it is possible to swell the knot of the desired shape at a predetermined position by pressing from the back side to the outside in the softened state by heating.

본 발명에 있어서 소재표면에 검정색 락카를 분사도포하여 사포질한 것은 회색으로 변한 균열부분과 표면에 락카가 침투 도포됨으로서 균열부분을 보강하는 동시에 색상을 검정색으로 바로 잡아 주며, 사포질을 하는 이유는 락카질한 표면 부분과 그을린 부분을 제거하여 원색으로 복원하게 되는데 이때 침투된 락카는 그대로 잔류됨으로서 균열부분이 검정색으로 나타나게 되어 표면이 자연미를 형성하게 된다.In the present invention, the black lacquer is sprayed and sanded on the surface of the material so that the cracks turn into gray and the lacquer is penetrated to the surface, thereby reinforcing the cracks and at the same time correcting the color to black. One surface part and the burned out part are removed to restore the primary color. In this case, the penetrated lacquer remains as it is, so the crack part appears black and the surface forms a natural beauty.

이상과 같이 본 발명에 의한 대용목재는 자연미와 고전미를 나타낸 것으로서 크고 작은 장식물에 이용되는 매우 실용적인 방법을 제공하는 것이다.Substitute wood according to the present invention as described above is to provide a very practical method used for the large and small decorations as showing the natural beauty and classic beauty.

[실시예]EXAMPLE

내부 가소화된 경질염화 비닐의 원통상 또는 판상의 /소재표면에 600℃이상의 고온급열의 화염으로 가하면 균열이 되면서 불꽃이 닿는 부분은 검은색으로 변하게 되고 동시에 가소화된 소재가 유연성을 얻게 된다.When the internal plasticized hard vinyl chloride is applied to the cylindrical or plate / material surface with a high-temperature rapid flame of 600 ° C or more, the cracked part becomes black and at the same time, the plasticized material has flexibility.

이때 이면에서 봉 또는 막대기로 외부로 압압하여 나무의 옹이 모양로 팽출나무의 옹이모양을 형성한다.At this time, by pressing the rod or stick on the outside to form a knot-shaped knot-shaped knot of wood.

다음 표면에 검정색 락카를 분사하고 전체적으로 고루 사포질하면 표면의 그을림 부분이 제거되어 원색으로 복원되고 균열 부분에는 검정색 락카만 남게 되므로 불규칙 균열상과 옹이가 형성된 대용목재를 얻게 된다.After spraying black lacquer on the surface and sanding it as a whole, the burned portion of the surface is removed to restore the primary color, and only black lacquer remains in the cracked portion, thereby obtaining substitute wood having irregular cracks and knots.
