Description
본 발명은 건축용 내장재에 관한 것으로서, 특히 폐기물인 제지슬러지와 폐석고를 이용하여 제조한 건축 내장재 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1.

일반적으로, 제지공장에서 종이를 만들고 최종 배출되는 제지슬러지는 납, 구리, 카드뮴, 비소, 수은 등의 중금속을 함유하고 있다. 따라서, 이들 제지슬러지를 단순 매립하거나 소각하여 처리하는 방법은 환경오염에 치명적인 영향을 미친다.In general, paper sludge produced at the paper mill and finally discharged contains heavy metals such as lead, copper, cadmium, arsenic, and mercury. Therefore, the method of simply landfilling or incineration of these paper sludges has a fatal effect on environmental pollution.
또한, 제지슬러지에는 석분이 함유되어 있어 이를 재활용 없이 폐기하는 것은 경제적인 측면에서도 바람직하지 않다.In addition, since the paper sludge contains stone powder, it is not economically desirable to dispose of it without recycling.
또한, 티타늄회사에서 다량으로 배출되는 폐기물인 폐석고 역시 카드뮴, 비소, 시안화합물 및 구리 등의 중금속이 함유되어 있다. 따라서, 이 폐석고를 상기 제지슬러지처럼 단순 매립하여 처리하는 것은 환경문제뿐만 아니라 경제적으로도 바람직하지 않다 할 것이다.In addition, waste gypsum, a large amount of waste emitted from titanium companies, also contains heavy metals such as cadmium, arsenic, cyanide and copper. Therefore, it is not economically desirable as well as environmental problems to treat this waste gypsum simply landfill like the papermaking sludge.
따라서, 종래부터 제지슬러지와 폐석고를 재활용하는 연구가 오랫동안 진행되어 달걀 받침대를 제조하는데 사용되기도 하였다. 하지만, 이 역시 위생상의 이유로 기피되고 있는 실정이다.Therefore, conventionally, researches for recycling paper sludge and waste gypsum have been progressed for a long time, and have been used to manufacture egg holders. However, this too is being avoided for hygiene reasons.
따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 창안된 것으로서, 본 발명의 목적은 제지슬러지와 폐석고를 재활용하여 경량의 단열, 불연및 방음효과가 뛰어난 건축용 내장재를 제공함에 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to recycle the paper sludge and waste gypsum to provide a lightweight building insulation with excellent heat insulation, non-combustible and soundproofing effect.

본 발명의 다른 목적 및 장점들은 하기에 설명될 것이며, 본 발명의 실시에 의해 알게될 것이다. 또한, 본 발명의 목적 및 장점들은 특히, 첨부된 특허청구범위에 나타낸 수단 및 조합에 의해서 실현될 수 있다.Other objects and advantages of the invention will be described below and will be appreciated by the practice of the invention. Furthermore, the objects and advantages of the invention can be realized in particular by the means and combinations indicated in the appended claims.
이하에서 본 발명의 바람직한 실시 예를 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail.
제지슬러지는 종이를 제조하는 처리과정에 각종 중금속에 오염되기 때문에 처리가 매우 어려울 뿐만 아니라 토양과 수질 및 대기를 심하게 오염시키는 오염물질이다. 일반적으로 제지슬러지를 구성하는 성분은 다량의 펄프 찌꺼기와, 납, 구리, 카드뮴, 비소, 수은 등의 중금속이 함유되어 있다. 또한, 이 제지슬러지는 석분을 일부 함유하고 있어 석고보드 대용의 제품을 만들어 합판 대용품인 건축용 내장재로의 개발을 용이하게 하는 조건을 가지고 있다.Paper sludge is not only difficult to treat because it is contaminated with various heavy metals during the paper manufacturing process, but also is a pollutant that severely pollutes soil, water and air. Generally, the constituents of paper sludge contain a large amount of pulp residue and heavy metals such as lead, copper, cadmium, arsenic, and mercury. In addition, this paper sludge contains a part of stone powder and has a condition for facilitating the development of building interior material, which is a substitute for plywood, by making a product for gypsum board.
또한, 티타늄회사에서 다량 배출되는 폐석고 역시 카드뮴, 비소, 시안화합물, 구리와 석분을 함유하고 있어 석고보드 대용의 제품을 만드는데 유리한 조건을 가지고 있다.In addition, waste gypsum emitted from titanium companies also contains cadmium, arsenic, cyanide compounds, copper and stone powder, making it an advantageous condition for making gypsum board substitutes.
따라서, 본 발명자들은 상기 제지슬러지와 폐석고를 기본원료로 하고 여기에 황토와 천연규조토를 부가하여 오염물질의 수치를 기준치 이하로 현저히 낮출 뿐만 아니라 탄산칼슘 등의 화학적 부재료를 첨가함으로써 단열 및 방음 특성이 우수한 건축용 내장재의 개발이 가능하다는 것을 발견하였다.Therefore, the inventors of the present invention make the paper sludge and the waste gypsum as the basic raw materials, and by adding ocher and natural diatomaceous earth to it, significantly lowering the level of contaminants below the standard value, and adding thermally insulating and soundproofing properties such as calcium carbonate. It has been found that the development of excellent building interior materials is possible.
본 발명의 건축용 내장재는 제지슬러지 39 - 66중량부, 폐석고 25 - 38중량부, 탄산칼슘 9 - 25중량부, 황토 13 - 25중량부, 규조토 25 - 34중량부, 라바(LAVA) 0.72중량부, 지당 5 - 12중량부, 삼산화안티몬 2 - 8중량부, 석고 25 - 34중량부, 이소옥틸알콜 0.06중량부 및 에틸실리케이트 0.09중량부를 포함한다.The building interior material of the present invention is 39 to 66 parts by weight of paper sludge, 25 to 38 parts by weight of waste gypsum, 9 to 25 parts by weight of calcium carbonate, 13 to 25 parts by weight of ocher, 25 to 34 parts by weight of diatomaceous earth, 0.72 parts by weight of LAVA. , 5-12 parts by weight, 2-8 parts by weight of antimony trioxide, 25-34 parts by weight of gypsum, 0.06 parts by weight of isooctyl alcohol and 0.09 parts by weight of ethyl silicate.
상기 제지슬러지와 폐석고는 본 발명의 건축용 내장재를 형성하기 위한 기본원료에 해당한다. 이때, 상기 제지슬러지의 중량이 39%를 하회하면 단열과 흡음성이 현저히 떨어지고, 66%를 초과하면 기계적강도, 불연성 및 내구성이 현저히 떨어진다.The paper sludge and waste gypsum correspond to the basic raw materials for forming the building interior material of the present invention. At this time, when the weight of the papermaking sludge is less than 39%, the insulation and sound absorption are significantly lowered, and if it exceeds 66%, the mechanical strength, nonflammability and durability are significantly decreased.
상기 황토는 전국 각처에 분포되어 있는 것으로서, 소성 색깔은 적갈색을 띄고 있고, 적벽돌, 내화벽돌의 제조에 사용된다. 특히, 도자기의 제조에 널리 사용되며 원적외선을 다량 함유하여 건강에 좋은 영향을 미친다.The loess is distributed throughout the country, the calcined color is reddish brown, it is used in the manufacture of red bricks, refractory bricks. In particular, it is widely used in the manufacture of ceramics, and contains a large amount of far infrared rays, which has a good effect on health.
상기 규조토는 가루로 산출되는 규산질의 원료이며 규조의 유해가 퇴적한 흙덩어리이다. 순수한 규조유해의 화학조성은 SiO296.16 - 96.80% 및 Al203+ Fe2O31.20 - 1.98%로 이루어진다. 좋은 규조토는 매우 가볍고 연하며 많은 기공 때문에 부피의 5배에 달하는 액체를 흡수할 수 있을 정도로 다공질이다. 규조토는 이와같은 다공질로 인한 여러 가지 특성을 지니고 있어 단열재, 시멘트 혼합재 등의 용도로 사용된다. 본 발명에 있어서는 특히, 경주 감포를 중심으로 한 지대에서 산출되는 규조토를 사용하는 것이 바람직하다.The diatomaceous earth is a siliceous raw material which is produced as a powder, and is a lump of dirt on which harmful substances of diatom are deposited. The chemical composition of pure diatomaceous harmful is composed of SiO 2 96.16-96.80% and Al 2 0 3 + Fe 2 O 3 1.20-1.98%. Good diatomaceous earth is very light, soft and porous enough to absorb up to five times the volume of liquid due to its many pores. Diatomaceous earth has various characteristics due to such porous, so it is used for insulation, cement mixture, etc. Especially in this invention, it is preferable to use the diatomaceous earth computed in the zone centered on a racing gampo.
상기 탄산칼슘은 무색, 무취의 가루 또는 결정형 분말고체로서 일반적으로 기재의 기계적 강도를 증가시키기 위해 첨가되는 충전재이다. 이때, 탄산칼슘은 수산화칼슘으로 대체하여 첨가될 수도 있다. 이렇게 탄산칼슘 대신 수산화칼슘을 대체 첨가하면 내장재의 중량은 무거워지지만 제조단가는 떨어지는 잇점이 있다.The calcium carbonate is a colorless, odorless powder or crystalline powder solid which is generally a filler added to increase the mechanical strength of the substrate. At this time, calcium carbonate may be added in place of calcium hydroxide. If calcium hydroxide is added instead of calcium carbonate, the weight of the interior material becomes heavy, but the manufacturing cost is lowered.
상기 삼산화안티몬은 재료의 연소성을 저하시키고 방지하기 위한 연소방지제의 일종이다.The antimony trioxide is a kind of anti-burning agent for reducing and preventing the combustibility of the material.
상기 이소옥틸알콜은 거품방지제이며, 상기 에틸실리케이트는 경화제의 일종이다.The isooctyl alcohol is an antifoaming agent, and the ethyl silicate is a kind of curing agent.
상기 석고는 기본원료를 보충하기 위해 첨가되는 보조원료이다.The gypsum is an auxiliary material added to supplement the basic material.
이때, 상기에 기술된 조성범위를 벗어나서 제조되는 내장재는 인장력, 흡음성, 불연성 등이 떨어져서 본 발명의 목적을 달성할 수 없게 된다.At this time, the interior material manufactured outside the above-described composition range is inferior in tensile force, sound absorption, non-combustibility, etc., the object of the present invention can not be achieved.
상기와 같은 조성으로 구성되는 본 발명의 조성물은 아래와 같은 제조공정을 통해 건축용 내장재로 재가공된다.The composition of the present invention composed of the composition as described above is reprocessed into building interior materials through the manufacturing process as follows.
39 - 66중량부의 제지슬러지와 25 - 38중량부의 폐석고를 물과 함께 미세한 분쇄기로 분쇄하여 겔화시킨 다음 거품방지제인 이소옥틸알콜 0.06중량부를 넣고 1차 희석시킨다.39-66 parts by weight of paper sludge and 25-38 parts by weight of waste gypsum are ground together with water and pulverized in a fine grinder, followed by gelling with 0.06 parts of isooctyl alcohol, an antifoaming agent, and firstly diluted.
여기에 에틸실리케이트 0.09중량부를 넣어 2차 희석시킨후 약 45분간 침전시킨다.0.09 parts by weight of ethyl silicate was added thereto, followed by a second dilution, followed by precipitation for about 45 minutes.
