Description

폐석을 이용한 복합소재의 제조방법{Nature Type Mixed Stone using the Waste Stone}Manufacturing method of composite material using waste stone {Nature Type Mixed Stone using the Waste Stone}

본 발명은 폐석을 이용한 복합소재의 제조방법에 관한 것으로, 더 상세하게는 천연석재의 질감표현 및 대량복제가 가능하고 각종 건축용품 토목건설용재로 사용가능한 폐석을 이용한 복합소재의 제조방법을 제공함에 있다.The present invention relates to a method for manufacturing a composite material using waste stone, and more particularly, to provide a method for manufacturing a composite material using waste stone, which is capable of expressing texture and mass replication of natural stone, and can be used as a civil construction material for various building products. have.

문명의 발달과 더불어 인간의 주거 문화의 고급화 성향은 날이갈수록 높아지고 이에 맞추어 주위환경에 대한 미적 요구도 높아지고 있는 실정이다. 주거환경을 아름답게 꾸민다는 것은 건축내외장재를 이용한 시공이나 토목공사 등을 통하여 달성되고 있다. 이러한 공사에는 강도도 좋고 그 장구한 수명의 점에서 각종 석재가 사용되고 있다.With the development of civilization, the propensity to upscale human culture is increasing day by day, and accordingly, the aesthetic demand for the surrounding environment is also increasing. Beautiful decoration of the residential environment is achieved through construction and civil engineering using interior and exterior materials. In such construction, various stones are used in terms of strength and long life.

한편 도시생활에 염증을 느끼는 도시인은 그 도시를 떠나서는 살 수 없는 구조적인 상황 하에서, 잠간씩 또 조금이나마 자연적인 감정을 불러일으켜 위안을 얻고자 할 의도에서 주택에 정원을 설치하여 자연석을 이송하여 가꾸고 있거나, 또 고급 접객업소 등지의 인테리어도 자연석을 그대로 옮겨서 조경하고 있는 실정이다.On the other hand, urban people who are irritated with urban life are transporting natural stones by installing gardens in their homes with the intention of arousing some natural feelings for a little bit and bringing comfort in a structural situation that cannot live outside the city. In addition, the interiors of high-end hospitality shops, etc., are also landscaped with natural stones.

자신이 살고 있는 주위환경을 아름답고 편안하게 조성한다는 것은 인지상정이지만 거기에는 자연석의 훼손이라고 하는 대가가 요구된다. 즉, 인간친화적인 건축 및 건설소재인 천연석재의 훼손은 그 심각성이 더욱 절실하다.It is assumed that it is beautiful and comfortable to create the surrounding environment in which you live, but there is a price called the damage of natural stone. In other words, the damage of natural stone, which is a human-friendly building and construction material, is more serious.

일반적으로 천연석재에는 화강암, 섬록석, 안산암, 현무암, 편암류, 사암, 사문암, 점판암, 대리석 등이 있다. 화강암은 국내에서 많이 생산되어 보편적으로 많이 쓰이는 석재로서 석질이 견고하고 내구성도 커서 대형재를 얻을 수 있고 아름다우며 물갈기를 하면 광택이 나는 것이지만 550℃ 이상에서는 표면 박리현상이 일어나 내화성이 부족하고 너무 단단하여 조각이나 가공에 어려움이 있다.Generally, natural stone includes granite, diorite, andesite, basalt, schist, sandstone, serpentine, slate, and marble. Granite is a stone that is widely used in Korea and is widely used. It is solid and durable, so it is possible to obtain large sized materials. It is beautiful and polished when it is watered. There is a difficulty in engraving or processing.

대리석은 내수성이 좋아 욕실 바닥재로서도 이용가능하며 색조가 미려하고 치밀하여 실내장식재로서는 가장 고급이지만 내화성이 약하고 산에 약하며 풍화하기 쉬워 외장재로는 부적당하다.Marble can be used as a bathroom flooring material because of its high water resistance. The beautiful color and fine color make it the most advanced material for interior decoration, but it is not suitable for exterior materials because it is weak in fire resistance, weak in acid and easy to weather.

그러나 이들 천연석재의 채취는 근본적으로 자연을 파괴하므로 오래전부터 그 대용품으로 인조석재를 사용하고 있다.인조석재에는 테라조, 외석, 수지계인조석, 세라믹 인조대리석 등이 있다. 테라조는 대리석 쇄조를 종석으로 취하고 시멘트를 이용하여 제조하는 것인데 연마하여 광택을 내는 모조석이며, 외석은 종석을 대리석 이외의 암석으로 사용한 것이다. 이들 인조석재는 천연석보다도 염가이지만, 중량이 무겁고 내화성이 부족한 단점이 있다.However, the extraction of these natural stones fundamentally destroys nature, and for a long time, artificial stone has been used as a substitute for artificial stone, such as terrazzo, external stone, resin artificial stone, and ceramic artificial marble. Terrazzo is a marble stone bath taken as a keystone and manufactured using cement. It is a polished imitation stone, and the external stone is used as a stone other than marble. These artificial stone is cheaper than natural stone, but has a disadvantage in that heavier weight and lack of fire resistance.

수지계인조석은 소정의 결합제를 액상으로 하여 만든 것인데 수지가 열경화성이기 때문에 경화가 급속하고 높은 압축강도가 단기에 얻어지며 균열이 적고 수밀성이 양호하며 방수성, 내마모성, 내산성 등의 잇점은 있으나, 열에 취약하여 내화성이 현저히 낮다고 하는 단점이 있다.Resin-based artificial stone is made of a predetermined binder in a liquid phase. Since the resin is thermosetting, it is hardened rapidly and high compressive strength is obtained in a short time. The disadvantage is that the fire resistance is remarkably low.

상기 세라믹 인조대리석은 무기원료를 만들어 소성한 자기질 인조대리석인데 천연대리석보다는 중량이 적으나 그다지 경량이라고는 할 수 없으며 제조여건 상 대형재보다는 다종 소형재로서 이용된다.The ceramic artificial marble is a magnetic artificial marble made of an inorganic raw material and calcined. The ceramic artificial marble has a weight less than that of natural marble, but is not very light, and is used as a variety of small materials rather than large materials.

이와 같이 건축용 내/외장재 또는 바닥용석재로 사용되는 천연석재나 인공석재는, 대부분 취도계수가 크고 대형품을 얻기 어려우며 비중이 크고 가공성이 불량하며 화열에 약한 현상이 있으며, 특히 천연석재의 경우에는 그 가공비의 상승으로 인하여 대량복제가 곤란하며 자연을 훼손한다고 하는 문제가 있다.As such, natural or artificial stone used as interior / exterior or floor stone for building is mostly hard to obtain a large product with a large grain coefficient, high specific gravity, poor workability, and weak heat, especially natural stone. Due to the increase in the processing cost, there is a problem that mass replication is difficult and damages nature.

이와 같이 업계에서는 천연석재 또는 인조석재의 장점만을 취한 새로운 개념의 신소재의 등장을 절실하게 용청받고 있다.In this way, the industry is urgently being asked for the emergence of a new concept of a new concept that takes only the advantages of natural or artificial stone.

본 발명은 상기 요청에 부응하여 개발된 발명으로서, 그 목적으로 하는 바는 천연석재의 질감표현 및 대량복제가 가능하고 각종 건축용품 토목건설용재로 사용 가능한 폐석을 이용한 복합소재의 제조방법을 제공함에 있다.The present invention has been developed in response to the above request, the object of the present invention is to provide a method for producing a composite material using waste stone capable of expressing the texture and mass replication of natural stone and can be used as civil construction materials for various building products. have.

이하, 첨부도면을 참조하여 본 발명의 폐석을 이용한 복합소재의 제조방법에 대하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a method for producing a composite material using the waste-rock of the present invention.

도 1은 본 발명의 제조공정을 나타낸 공정도이다.1 is a process chart showing a manufacturing process of the present invention.

먼저, 폐석재, 돌가루 등을 폐광이나 석재 가공공장 또는 석산등지에서 운반하여 일정한 크기 이하로 입자를 선별, 분쇄한다(S100공정). 이때의 선별기, 분쇄기(또는 쇄석기)는 통상의 것을 사용하며 보통 크기 13mm 이하의 골재를 선별하여 분쇄한다.First, the waste stone, stone powder, etc. are transported in a waste mine or stone processing plant or quarries to sort and crush particles to a predetermined size or less (S100 process). At this time, a sorting machine, a crusher (or a crusher) uses a conventional one, and selects and crushes aggregates having a size of 13 mm or less.

이어서 분쇄된 돌가루에 뭍은 불순물이나 각종 오염물, 먼지 등을 제거하기 위하여 세척한다(S102공정). 이때에는 소정의 용기에 넣어 세척하거나 흐르는 물로 세척하는 등 그 세척방식에는 아무런 제약을 받지 않는다. 이어서 상기 세척 돌가루를 완전하게 건조시킨다(S104공정). 이 건조의 경우에도 하절기에는 자연건조하고 우천시 또는 동절기에는 항상 +30℃ 정도를 유지하는 온풍실에 넣어 온풍건조한다.Subsequently, it is washed to remove impurities, various contaminants, dust, etc., which have been crushed into the crushed stone (step S102). At this time, washing in a predetermined container or washing with running water is not limited to the washing method. Subsequently, the washing stone is completely dried (step S104). Even in the case of drying, it is dried naturally in the summer season and in the warm air room which always maintains about + 30 ℃ during the rainy season or winter season, and the warm air is dried.

잘게 부수어지고 건조된 쇄석을 혼합조로 이송하여 소정의 약품, 바람직하게는 불포화 폴리에스테르계 수지 10∼20%, 충진제, 예를들면 CaCO315∼30%, 경화제로서 수지대비 2∼5% 를 상기 건조된 돌가루와 혼합한다(S106공정).The finely crushed and dried crushed stone is transferred to a mixing tank so that a predetermined chemical, preferably 10 to 20% of an unsaturated polyester resin, a filler such as C a CO 3 15 to 30%, and a curing agent 2 to 5% of the resin To mix with the dried stone (step S106).

제조하고자 하는 제품의 형상을 본뜬 몰드를 미리 준비하고, 이 몰드에 이형제를 도포한 후 상기 약품과 혼합된 돌가루(이하, '성형재' 라 함)를 넣어 성형한다(S108공정). 이때 상기 몰드에는 소정의 진동장치가 연결되어 있어 몰드가 진동하게 됨에 따라 상기 성형재를 이루는 수지와 약품이 골고루 섞이게 된다. 이와 동시에 상기 몰드에, 예를들면 압축강도 1.5∼3ton의 압력을 가하여 몰드구조를 더욱 치밀하게 한다.After preparing a mold in accordance with the shape of the product to be prepared in advance, a mold release agent is applied to the mold, and then mixed with the medicine (hereinafter referred to as a 'molding material') is molded (S108 step). At this time, a predetermined vibration device is connected to the mold, so that the mold and the resin forming the molding material are evenly mixed as the mold vibrates. At the same time, a pressure of, for example, a compressive strength of 1.5 to 3 ton is applied to the mold to further densify the mold structure.

몰드성형 후 일정 시간이 경과하하여 성형재가 경화하면 탈형하는 과정을 끝으로 원하는 천연석재의 질감을 가지는 소정의 제품이 완성된다(S110공정).After a certain period of time after the mold molding, when the molding material is cured, a predetermined product having a desired natural stone texture is completed after the process of demolding (S110 process).

상기 공정 중 탈형 후 자외선차단용 도료를 도포하면 더욱 질감있는 천연석재의 재현이 가능하다.After demolding in the process, by applying a UV-protective paint it is possible to reproduce a more textured natural stone.

상기 혼합공정 전에 안료와 약품을 배합하여 미리 원하는 색조를 설정한 후 혼합하게 되면 완성된 후의 제품의 표면뿐만 아니라 돌 속까지도 표면과 동일한 색조를 가지는 제품의 완성이 가능하게 된다.By mixing the pigment and the drug before the mixing process to set the desired color tone in advance and then mixing it becomes possible to complete the product having the same color tone as the surface of the finished product as well as the stone.

이와 같은 공정을 거쳐 제조되는 본 발명의 폐석을 이용한 복합소재의 제조방법은 다음과 같은 물적 특성을 가진다.The manufacturing method of the composite material using the waste-rock of the present invention manufactured through such a process has the following physical properties.

상기 표 1에서 알 수 있는 바와 같이 본 발명은 종래의 일반적인 건축재인 시멘트 콘크리트품에 비하여 압축강도, 탄성계수, 휨강도, 인장강도, 전단강도 및 흡수율의 면에서 매우 뛰어난 물적특성을 가지고 있음을 알 수 있다.As can be seen from Table 1, the present invention has excellent physical properties in terms of compressive strength, modulus of elasticity, flexural strength, tensile strength, shear strength, and water absorption, as compared to cement concrete products which are conventional general building materials. have.

이와 같이 표 2에 의하면 본 발명은 시멘트콘크리트에 비하여 내약품성 및 외관변화에 뛰어난 특성을 보이고 있음을 알 수 있다.As such, according to Table 2, it can be seen that the present invention shows superior properties in chemical resistance and appearance change as compared with cement concrete.

이와 같이 본 발명은 석재를 분쇄하여 불포화 폴리에스터 수지와 혼합되므로 수지특성인 내산성, 내염성이 뛰어나기 때문에 항상 외부 기후에 노출되어 산성비, 공해 등의 외부요인에 시달리는 건축외장재나 환경구성물에 적용하면 화학적 내구력이 다른 재료들과 비교할 때 수명이 길다.As described above, the present invention is crushed stone and mixed with unsaturated polyester resin, so it is excellent in acid and flame resistance, which is a resin characteristic. Therefore, when applied to building exterior materials or environmental components that are exposed to external factors such as acid rain and pollution, Durability is longer compared to other materials.

수지와 분쇄된 폐석재가 섞이는 과정에서 유연한 형태로 되기 때문에 몰드에 의하여 천연석재로는 표현이 어려웠던 곡면생산이 가능하고 대량생산이 가능하다.Since the resin and the crushed waste stone is mixed in a flexible form, it is possible to produce a curved surface and mass production, which was difficult to express with natural stone by the mold.

결합제로서 불포화 폴리에스터 수지를 사용하기 때문에, 강한 인성을 발휘하여 시멘트 콘크리트에 비하여 압축강도가 약 4배 높고 휨강도는 6배 이상이다. 수명은 반영구적이며 흡수율이 0.005%∼0.1%에 불과하여 방수성이 높아 욕실바닥재로서 대리석보다도 더 우수한 성질을 가지고 있고 동절기에 동파염려가 없어 4계절 기후변화가 심한 지역의 건축재로서 적합하다.Since the unsaturated polyester resin is used as the binder, it exhibits strong toughness and has a compressive strength of about 4 times higher than that of cement concrete and 6 times or more of flexural strength. Its life span is semi-permanent and its water absorption rate is only 0.005% ~ 0.1%, so it is waterproof and has better properties than marble as a bathroom flooring material.

마모율은 시멘트 콘크리트에 비하여 1/5 정도에 불과하여 내마모성이 요구되는 보도블럭, 계단석, 바닥재로서 유용하고 두께에 한계가 있는 천연석재에 비하여 더 얇게 성형할 수 있어 경량화를 달성하므로 건축물의 하중부담을 줄여 외장재로서 적합하다.The wear rate is only 1/5 of that of cement concrete, which is useful as sidewalk blocks, staircases, and flooring materials that require abrasion resistance, and can be formed thinner than natural stone, which has a limited thickness. In short, it is suitable as an exterior material.

이와 같이 본 발명은, 석재복합 신소재로서 우리의 주변환경을 조성하는 건설현장의 시멘트, 철, 천연석 등의 토목 건설자재 또는 건축자재의 대용품으로서, 폐광이나 산업현장 등에서 버려지는 대규모의 폐석들을 분쇄, 탈수, 건조 후 폴리에스테르 약품과 혼합하여 몰드성형하여 각종 건축용품을 제조함으로써 천연석재와 동일한 질감을 표현하게 된다.Thus, the present invention, as a substitute for civil construction materials or construction materials such as cement, iron, natural stone, etc. of construction sites that create our surrounding environment as a stone composite new material, crushing the large-scale waste stones discarded in abandoned mines or industrial sites, After dehydration and drying, it is mixed with polyester chemicals and molded to manufacture various building products, thereby expressing the same texture as natural stone.

천연석재의 대용품으로 사용되는 인조석재와는 그 제조개념이 다른 것으로 천연석재와 동일한 질감표현이 가능하며 표면은 물론 속층까지 동일한 색조로 제조될 수 있다.The concept of manufacturing is different from that of artificial stone used as a substitute for natural stone, and the same texture can be expressed as natural stone, and the surface as well as the inner layer can be manufactured in the same color tone.

또한 몰드에 의한 압출성형공법이 가능하므로 천연석재의 석조각 개념에서 탈피하여 동일 형상의 물품을 대량생산가능하게 된다. 천연석재에서 표현하지 못하는 대량생산과 곡면가공, 판재제조, 릴리프 등 어떠한 디자인으로도 완벽하게 연출할 수 있다.In addition, since the extrusion molding method by the mold is possible, it is possible to mass-produce the article of the same shape by escaping from the concept of stone carving of natural stone. It can be perfectly produced by any design such as mass production, surface processing, plate manufacturing, and relief that cannot be expressed in natural stone.

본 발명의 산업상 이용분야는 무궁무진하다. 각종 건축물의 내/외장재는 물론이거니와 우리주변에서 흔히 볼 수 있는 제품을 간단하게 들자면, 거리환경조성물(street furniture)로서 보도블럭, 벤취, 가로수보호대, 도로의 경계석, 맨홀 등이 있고, 간이자판대, 공중전화박스, 펜스기둥, 각종 간판류, 석재화분, 수목보호대, 석재 악세서리, 인테리어 소품, 고급 벽돌, 타일, 개와, 자연호박돌과 같은 환경조형물 등이다.The industrial fields of use of the present invention are endless. As well as the interior and exterior materials of various buildings, the products commonly found around us are street furniture, which include sidewalk blocks, benches, roadside guards, road boundaries, manholes, and simple kiosk. , Public telephone boxes, fence pillars, various signs, stone flower pots, tree guards, stone accessories, interior accessories, fine bricks, tiles, dogs, and environmental sculptures such as natural pumpkin stones.

석재로 가공할 수 있는 모든 제품 또는 몰드성형이 가능한 모든 제품을 실물 그대로 색조나 질감을 100% 재현 복제가능하며 곧바로 대량생산으로 이어지는 획기적인 발명이다.All products that can be processed into stone or all products that can be molded can be reproduced in 100% reproduction of color or texture as it is, and this is a revolutionary invention that leads directly to mass production.

그리고 본 발명은 그 외장적 질감표현의 자유도, 응용도 뿐만 아니라 인조석재에 비하여 그 기능도 우수하다. 예를들면 물리, 역학적 특성과 내약품성이 월등히 우수하다.In addition, the present invention is excellent in functionality as compared to the artificial stone as well as the degree of freedom and application of the exterior texture. For example, the physical and mechanical properties and chemical resistance are excellent.

이상 설명한 바와 같은 본 발명의 폐석을 이용한 복합소재의 제조방법에 의하면, 쓸모없이 버려지는 폐석을 이용하여 소정의 수지와 약품을 첨가하여 몰드성형함으로써 적은 비용으로 천연석재의 아름다운 질감을 표현할 수 있기 때문에 기존의 고가로 쓰이던 천연석재를 대체함과 동시에 수요자의 요구에 무분별하게 대응하여 석재를 파헤치는 일이 없으므로 환경을 파괴하지 않는 큰 장점이 있다.According to the manufacturing method of the composite material using the waste-rock according to the present invention as described above, by using a waste stone that is discarded obsolete by adding a predetermined resin and chemicals to mold molding, the beautiful texture of the natural stone can be expressed at a low cost At the same time, it replaces the existing expensive natural stone and at the same time does not destroy the stone indiscriminately responding to the needs of the consumer has a great advantage that does not destroy the environment.

또 본 발명은 폐기되는 자연석재를 분쇄하여 적절하게 재가공하여 다른 용도의 천연석재로서 다시 탄생하게 하는 기술이므로 자연을 보호하고 생태계의 파괴를 방지하며 각종 형상의 제품들을 제조할 수 있어 주위환경이 미려해지며 천연석재보다도 더 장구한 수명을 가지므로 보수, 관리에도 큰 잇점이 있다.In addition, the present invention is a technology for crushing the discarded natural stone to be re-processed appropriately to be reborn as a natural stone for other uses, thus protecting nature, preventing the destruction of the ecosystem and manufacturing products of various shapes, so that the surrounding environment is beautiful It has a longer lifespan than natural stone, so it has a big advantage in maintenance and management.
