본 발명은 합성목재에 관한 것으로, 특히 압출기와 금형, 냉각수조, 그리고 인취기를 거쳐 압출되는 압출물 표면에 미끄럼 방지 기능이 우수한 무기물을 압입하여 마루판과 같은 합성목재의 표면이 수분에 젖더라도 보행자의 미끄럼 사고를 방지하도록 구성된 미끄럼 저항성이 향상된 합성목재 제조장치 및 방법과 이로부터 제조된 합성목재에 관한 것이다.
The present invention relates to a synthetic wood, in particular, by injecting an inorganic material having excellent anti-slip function to the surface of the extrudate extruded through an extruder, a mold, a cooling water tank, and a take-off machine, even if the surface of the synthetic wood such as floorboards wet with moisture The present invention relates to a synthetic wood manufacturing apparatus and method and a synthetic wood produced from the improved sliding resistance configured to prevent the sliding accident of.

근래에 들어 천연목재에 대한 소비자의 선호도가 크게 증가하고 있으며 또한 전세계적으로 환경 보존 문제가 크게 대두되고 있다.In recent years, consumers' preference for natural wood has been greatly increased, and environmental preservation problems are emerging all over the world.

이에 따라 천연목재와 유사한 표면 질감 및 무늬를 갖는 합성목재에 관한 연구가 많이 이루어지고 있는데, 이러한 합성목재를 제조하는데 사용되는 목재의 대부분은 비중이 비교적 가볍고 구하기가 쉬워 많이 이용되고 있다.Accordingly, many studies on synthetic wood having a surface texture and pattern similar to natural wood have been conducted. Most of the wood used to manufacture such synthetic wood has a relatively low specific gravity and is easy to obtain.

상기 합성목재는 목재부스러기(대패밥,톱밥)와, 발포제(發泡劑)를 혼합한 플라스틱을 성형할 때 발포시켜서 천연목재와 비슷한 외관이나 성질을 갖게 한 재료로서 사출 또는 압출성형으로 제조되며, 사출성형품은 텔레비전 수상기의 캐비닛 등에, 압출성형품은 건재에 주로 사용된다. The synthetic wood is manufactured by injection or extrusion molding as a material having a similar appearance or properties to natural wood by foaming when shaping plastics mixed with wood chips (scallops, sawdust) and blowing agents (發泡劑), Molded products are mainly used for cabinets of television receivers, and extruded products are mainly used for building materials.

상기 플라스틱 원료로서는 폴리스타이렌?ABS수지 등이 쓰이고, 사출(射出) 또는 압출성형으로 제조된다. 사출성형품은 성형 시에 조각이나 나무결무늬가 넣어지므로 인쇄나 도장(塗裝) 등의 2차 가공을 하지 않고서도 나무의 질감(質感)을 나타낼 수 있다. As the plastic raw material, polystyrene, ABS resin or the like is used, and is produced by injection molding or extrusion molding. Since the injection molded articles are engraved or grained during molding, the texture of the wood can be exhibited without performing secondary processing such as printing or painting.

압출성형품의 경우에는 목재의 제재, 평판, 각재(角材) 등에 가까운 것이 되며, 주된 용도는 건재(建材)이다. 압출된 시트(sheet)를 뜨거울 때 감아서 나이테가 있는 통나무와 비슷한 것도 만들 수 있다. 일반적으로 합성목재는 천연목재에 비해서 흡수성이 적고 부패하지 않는 장점이 있다. 또 발포배율(發泡倍率)이 비교적 낮고 표면에 밀도가 높은 표피층이 있으므로 강도가 상당히 높고 못박기나 대패질 등의 가공도 가능하다. 다만, 세로 방향의 강도가 뒤지고 휨이 크다는 결점을 가진다.In the case of an extruded article, it is close to the wood material, the flat plate, the lumber, etc., and the main use is a building material. The extruded sheet can be wound up to make it resemble a tree with logs. In general, synthetic wood has the advantage of less absorption and decay than natural wood. In addition, since the foaming ratio is relatively low and there is a dense skin layer on the surface, the strength is considerably high, and the processing of nailing and planer is also possible. However, it has the disadvantage that the strength in the longitudinal direction is inferior and the warpage is large.

목재 자원은 세계적으로 감소되는 경향이 있고, 석유화학설비의 대형화에 수반되는 신제품 개발의 필요성도 있으므로 합성목재는 합성종이와 함께 장차 상당히 성장하고 석유화학공업에서 큰 수요를 형성할 것이다. 그러나 천연목재와의 가격차 축소, 플라스틱의 강도?강성(剛性) 부족의 해결, 폐기물 처리대책 확립이 과제이다. As timber resources tend to decrease globally, and there is a need to develop new products that accompany the enlargement of petrochemical facilities, synthetic wood will grow considerably with synthetic paper in the future and create great demand in petrochemical industry. However, the challenge is to reduce the price gap with natural wood, to solve the lack of strength and rigidity of plastics, and to establish waste disposal measures.

이러한 합성목재는 강하고 우수한 물성과 더불어 친환경적이며, 재생이 가능하여 목재를 대체하는 신소재로서 그 시장이 급성장하고 있으며 다양한 형태의 합성목재 제품이 개발되고 있는 실정이다.Such synthetic wood is a new material that replaces wood because of its strong, excellent properties, eco-friendly and renewable, and its market is growing rapidly, and various types of synthetic wood products are being developed.

한편, 우천시의 강우(降雨), 또는 동절기에 눈(雪) 등으로 인해 마루판과 같은 합성목재의 표면이 수분에 젖을 경우 건조한 상태보다 상대적으로 미끄러우기 쉽게 되며, 이 경우 보행자의 미끄럼 사고를 유발한다.On the other hand, if the surface of synthetic wood such as floorboards gets wet with moisture due to rain or rain in winter, it becomes more slippery than dry, which in turn causes pedestrian accidents. .

이에, 이러한 문제를 해결하기 위해 다양한 방법들이 시도되어 왔다. 일례로서, 패턴(pattern) 시공 방법을 통해 제품상의 무늬가 엇갈리게 하는 방법, 미끄럼 방지 테이프를 덧붙이는 방법, 제품 표면에 일정한 홈을 내는 방법 등이 주로 사용되고 있다. Accordingly, various methods have been tried to solve this problem. As an example, a method of staggering the pattern on the product through a pattern construction method, a method of adding an anti-slip tape, a method of forming a constant groove on the surface of the product, etc. are mainly used.

그러나, 이러한 방법으로는 미끄럼 저항성이 크게 개선되지 않고 있는 실정이다. 이에 따라 미끄럼 저항성이 보다 향상된 합성목재의 개발이 시급한 상태에 있었다.
However, this method does not significantly improve the slip resistance. As a result, there was an urgent need for the development of synthetic wood with improved sliding resistance.
