Description

폐목재 및 어패류 잔해물로 만든 인조 대리석 및 그의 제조방법Artificial marble made from waste wood and shellfish debris and its manufacturing method

본 발명은 폐목재 및 어패류 잔해물로 만든 인조 대리석 및 그의 제조방법에 관한 것이다. 더욱 상세하게는 목분, 죽분 및 폐자재 등의 폐목재와 어패류 등의 잔해물과 같은 폐기물 들을 미세하게 분쇄한 후 염화비닐수지, 안정제인 방향족아민화합물과 활제인 스테아린산염을 고온에서 혼합 성형하여서 제조되는 기존의 대리석을 대신하여 사용될 수 있는 인조 대리석과 이를 제조하는 방법에 관한 것이다.The present invention relates to an artificial marble made from waste wood and shellfish debris and a method of manufacturing the same. More specifically, finely pulverized waste materials such as wood waste, bamboo flour and waste materials such as debris such as fish and shellfish, and then produced by mixing and molding a vinyl chloride resin, an aromatic amine compound as a stabilizer and a stearate as a lubricant at high temperature It relates to artificial marble which can be used in place of the existing marble and a method of manufacturing the same.

현재, 삼림, 농지, 제재소, 건설 현장, 펄프 공법 등에서 많은 폐목이 생성되고 있고, 또 무분별한 벌목으로 인해 발생되는 잡목이나 수익성과 이용 가치를 잃고 있는 대나무 등이 폐자재로 많이 생성되고 있다.Currently, a lot of waste wood is generated in forests, farmland, sawmills, construction sites, pulp processes, etc., and a variety of waste materials are generated as miscellaneous materials generated by indiscriminate logging and bamboo that loses profitability and value.

이러한 폐자재 들은 건축 자재나 다른 재생품으로 제대로 활용하고 있지 못하여 지금까지 전세계적으로 커다란 환경 문제를 일으켜 왔다.These waste materials have not been properly used as building materials or other remanufactured materials, and thus have caused huge environmental problems worldwide.

더욱이, 우리 나라의 수종은 원목으로 사용하는 것이 불가능하기 때문에 천연 목재를 전량 수입에 의존하고 있어 앞으로도 이러한 수종의 처리 문제가 상당히 심각한 실정이다.Moreover, because the species in our country cannot be used as timber, we rely on the import of natural wood as a whole, so the problem of processing such species is very serious in the future.

또한, 우리 나라는 삼면이 바다로 둘러싸여져 있어 수산자원이 풍부한 나라중의 하나인 반면에 현재 해안지방에는 마구 버려지는 어패류 등의 잔해물이 산업 공해를 유발시키고 있다.In addition, our country is one of the countries rich in aquatic resources because it is surrounded by the sea on three sides. Currently, debris such as fish and shellfish that are thrown away in coastal areas cause industrial pollution.

즉, 해안 지방에는 조개 껍데기는 물론 버려지는 쓰레기들이 상당히 많아 바다가 오염되고 있고, 그로 인해 심각한 녹조 현상까지 발생하여 이의 해결에 상당히 많은 시간과 자본을 투자하고 있다.In other words, there are many sea shells and discarded wastes in the coastal area, which pollutes the sea, which causes severe green algae, which is a significant investment of time and capital.

하지만, 지금까지 어패류 등의 잔해물이 공해의 한 원인이 되고 있다는 사실을 알고 있으면서도 이의 처리방법에 대해서는 상당히 미미한 실정이다. 특히 어민들도 수익성의 차원에서 어패류 등의 잔해를 그대로 바다에 방치하고 있다.However, while knowing that the debris such as fish and shellfish is one of the causes of the pollution so far, how to handle it is quite insignificant. In particular, fishermen are leaving the remains of fish and shellfish in the sea as a way of profitability.

본 발명자들은 종래의 이러한 문제들을 해결하기 위하여 예의 연구를 거듭한 결과, 우리 나라에서 생성되고 있는 수종이나 폐목, 잡목 및 대나무 등의 폐목재와, 굴, 조개, 생선뼈 등의 어패류 잔해물을 원자재로 하고 여기에 열가소성 수지등을 배합한 후 성형하여 인조 대리석을 제조할 경우, 폐목재나 어패류 등의 잔해물과 같은 폐기물로 인한 환경 오염을 방지할 수 있고, 이에 따라 산촌이나 어촌의 생활 환경도 향상시킬 수 있을 뿐만 아니라 건축 자재인 기존의 대리석이 가지고 있는 여러 단점도 해결할 수 있음을 알게 되어 본 발명에 이르게 되었다.As a result of intensive research to solve these problems, the present inventors have used raw materials such as species, waste wood, lumber and bamboo, and fish and shellfish debris such as oysters, shells and fish bones as raw materials. In the case of manufacturing artificial marble by molding a thermoplastic resin and then mixing it, it is possible to prevent environmental pollution caused by waste such as waste wood and fish and shellfish debris, thereby improving the living environment of mountain villages and fishing villages. The present invention has been found to be able to solve not only a number of disadvantages of the existing marble which is a building material but also can be solved.

이에 본 발명은 산업 환경 문제를 해결할 수 있고, 건축 자재로서 특히 유용한 폐목재 및 어패류 잔해물을 염화비닐수지에 혼합하여 제조된 인조 대리석 및 이를 제조하는 방법을 제공하는데 그 목적이 있는 것이다.Accordingly, an object of the present invention is to provide an artificial marble prepared by mixing waste wood and shellfish debris with vinyl chloride resin, which is particularly useful as a building material, and a method of manufacturing the same.

본 발명의 인조대리석의 제조는 100 내지 110 메시 크기로 미분된 폐목재 50 내지 60중량%와 어패류 잔해물 10 내지 20중량%를 염화비닐수지 25 내지 35중량%, 안정제인 방향족아민화합물과 활제인 스테아린산염 0.5 내지 1.5중량%에 첨가하여 150 내지 160℃의 고온에서 혼합한 후 압출하여 대리석의 자연 무늬가 발생하도록 시트 형태로 롤러 가공처리를 한 다음 100 Kg/cm2이상의 압력 하에 표면 가공처리를 하여서 제조한다.Preparation of the artificial marble of the present invention is 50 to 60% by weight of finely divided waste wood to 100 to 110 mesh size and 10 to 20% by weight of fish and shell debris 25 to 35% by weight of vinyl chloride resin, aromatic amine compound as a stabilizer and stearic acid as a lubricant It is added to 0.5 to 1.5% by weight of salt, mixed at a high temperature of 150 to 160 ° C, extruded, and processed into a roller to form a natural pattern of marble, followed by surface processing under a pressure of 100 Kg / cm 2 or more. Manufacture.

본 발명에 의해 제조되는 인조 대리석의 원자재로서 사용되는 폐목재로는 농지, 건축 현장, 제재소와 같은 각종 목재 취급소, 산에서 자유분방하게 성장하거나 벌목 시 발생된 잡목, 왕겨 및 생산성과 연결되지 못한 대나무 등과 같은 모든 목재를 포함한다.Waste wood used as a raw material of the artificial marble produced by the present invention is a variety of wood handling such as farmland, construction sites, sawmills, bamboo freely grown in the mountains or unconnected with crops, chaff and productivity It includes all timbers as such.

본 발명에서 원자재로 사용하는 어패류 잔해물로는 바닷가에 버려지고 있는 조개, 굴 껍데기 및 생선뼈 등을 포함한다.The fish and shellfish debris used as raw materials in the present invention include shellfish, oyster shells, fish bones, etc. that are discarded on the beach.

본 발명의 인조 대리석을 제조하는 방법은 상기한 폐목재를 먼저 조분쇄기를 이용해서 조분하고, 조분된 분쇄물을 미분쇄기에 넣고 100 내지 110 메시 크기로 미분을 한다.In the method of manufacturing the artificial marble of the present invention, the waste wood is first milled using a coarse mill, and the coagulated mill is put into a mill and finely divided into 100 to 110 mesh.

별도로 상기의 어패류 잔해물을 건조로에 넣고 살균 처리를 하고, 살균된 어패류 잔해물을 역시 일정 크기로 조분쇄한 후 100 내지 110 메시 크기로 미분을 한다.Separately, the fish and shellfish debris is put into a drying furnace and sterilized, and the sterilized fish and shellfish debris is also coarsely ground to a predetermined size and finely divided into 100 to 110 mesh.

상기와 같이 미분된 목분 50 내지 60중량%와 어패류 잔해물 10 내지 20중량%를 열가소성 합성 수지 25 내지 35중량%, 안정제와 활제 0.5 내지 1.5중량%와 함께 혼합하여 고열 믹서기에서 1차로 가공을 한다.50 to 60% by weight of finely divided wood powder and 10 to 20% by weight of fish and shellfish residue are mixed together with 25 to 35% by weight of thermoplastic synthetic resin, 0.5 to 1.5% by weight of stabilizer and lubricant and processed first in a high temperature mixer.

상기 1차 가공의 순서는 먼저 염화비닐수지와 안정제인 방향족아민화합물과 활제인 스테아린산염을 고열 믹서기에 넣고 130℃까지 혼합을 한 후 상기 미분된 목분과 어패류를 넣고 다시 150 내지 160℃까지 가공하여 안정제와 염화비닐수지, 목분, 어패류 분쇄물이 골고루 섞이도록 가공을 한다.The first step of the process is to first put the vinyl chloride resin, the aromatic amine compound as a stabilizer, and the stearic acid salt as a lubricant in a high temperature mixer, and to mix it up to 130 ℃, and then put the finely divided wood flour and fish and shellfish and processed to 150 to 160 ℃ Process the stabilizer and the vinyl chloride resin, wood flour, and crushed fish and shells evenly.

1차 가공된 배합물을 포장을 하여 저장하였다가 장기간 후에 사용을 해도 상관없지만, 150 내지 190℃의 온도 조건하에서 압출기나 밤바리 혼합기를 통해 함침 과정을 수행(2차 가공)하고, 진흙 덩어리와 같은 상태가 된 재료를 대리석의 자연적인 무늬를 갖도록 하기 위해서 150 내지 200℃의 온도하에서 특수 롤러 가공을 신속하게 실시할 수 있다.Although the primary processed formulation may be packaged and stored for a long time, it may be used, but the impregnation process (secondary processing) may be carried out through an extruder or a chestnut mixer under a temperature condition of 150 to 190 ° C. Special roller processing can be performed quickly at the temperature of 150-200 degreeC, in order to make the material which became the state have the natural pattern of a marble.

추가로 대리석 표면 광택의 가공을 위해 시트 상태로 된 재료를 가압 프레스를 통해서 1차로 100kg/cm2이상으로 가압한 후, 제품의 밀도, 예를 들면 탄성과 경도 등을 조정하기 위해 이차로 다시 300 Kg/cm2이상의 압력을 가한 후, 표면 보호를 위해서 실외벽으로 사용할 경우에는 0.1 내지 0.15 mm의 두께로, 바닥재로 사용할 경우에는 0.5 내지 1 mm의 두께로 자외선 코팅을 하면 기존의 대리석을 대신할 수 있는 수명이 긴 인조 대리석이 제조되게 된다.In addition, the sheet-like material is first pressurized to 100 kg / cm 2 or more through a pressing press for the processing of the marble surface gloss, and then again to the secondary 300 to adjust the density of the product, for example, elasticity and hardness. After applying a pressure of Kg / cm 2 or more, UV coating with a thickness of 0.1 to 0.15 mm for surface protection and 0.5 to 1 mm for flooring can replace conventional marble. Long lasting artificial marble is produced.

본 발명의 방법에 따라 제조된 인조 대리석은 기존의 대리석에 비해 여러 가지 측면에서 유용하다. 즉, 기존의 대리석은 대부분 수입에 의존하고 있고, 가격이 고가이며, 치수에 맞게 자르기 어렵고 중량이 무거워 사람이 다루기가 불편할 뿐 아니라 안전사고의 발생도 많은 등 건설 현장에서 사용상에 문제점이 많고 또 사용하고 남은 조각은 이용 가치가 없어 곧장 산업 쓰레기로 변하여 환경을 해치는 문제가 있었다.Artificial marble prepared according to the method of the present invention is useful in several aspects compared to conventional marble. In other words, the existing marble is mostly dependent on imports, is expensive, difficult to cut to size and heavy, which makes it difficult for humans to handle and causes many safety accidents. The remaining pieces have no value in use, and have turned into industrial waste straight away, harming the environment.

그러나, 본 발명의 방법에 의해 제조된 인조 대리석은 폐목재와 어패류 잔해물 등의 폐기물을 원자재로 하여 제조하고 있으므로 원자재의 수급 측면에서 가격이 저렴하고, 중량이 가벼워 취급하기에도 수월하고, 안전 사고도 예방할 수 있을 뿐 아니라, 사용하고 남은 조각은 전량 수거하여 재생이 가능하여 산업 쓰레기의 발생을 최대한 줄일 수 있는 특징이 있다.However, since the artificial marble manufactured by the method of the present invention is manufactured from waste materials such as waste wood and fish and shellfish debris as raw materials, it is inexpensive in terms of supply and demand of raw materials, is light in weight, is easy to handle, and also safety accidents. Not only can it be prevented, but the remaining pieces can be collected and recycled to minimize the generation of industrial waste.

또한, 본 발명의 인조 대리석은 버려지는 폐목과 바닷가의 폐류 껍데기를 이용하여 제조한 것이므로 산업 환경을 크게 개선시킬 수 있는 바, 예컨대 잡목이나 왕겨 등을 이용하므로 농촌의 경제에 도움을 줄 수 있고, 어패류를 이용하게 되므로 어촌의 경제에도 도움을 줄 수 있는 등의 부수적인 효과가 따르게 된다.In addition, the artificial marble of the present invention is manufactured by using waste wood and waste shells of the seashore, which can greatly improve the industrial environment, for example, by using lumber or chaff can help the economy of the rural, The use of fish and shellfish will have side effects, such as helping the economy of the fishing village.
