Description
본 발명은 건축물 내장재에 관한 것으로, 더욱 상세하게는 황토에 물을 혼합한 후 짚을 다시 혼합하여 제조함으로써 단열성,보온성,방음성,흡음성,준불연성을 가지고 내장재의 경량화을 가지고 한 건축물 내장재에 관한 것이다.The present invention relates to a building interior material, and more particularly, to a building interior material having a light weight of the interior material having heat insulation, heat insulation, sound insulation, sound absorption, quasi-non-combustibility by manufacturing the straw again after mixing the water with ocher.
일반적으로 건축물의 벽체 또는 사무실의 칸막이,천정 등에 사용되는 내장재는 보통 판재 형태로써 보온,단열,방음,흡음,보온성을 유지하는 것이 주 목적이며, 이러한 목적을 달성하기 위한 종래 내장재로서 암면,스티로폼,유리솜,석면 등이 주로 사용된다.In general, the interior materials used in the walls of buildings or partitions, ceilings, etc. of the building is usually in the form of a plate, the main purpose is to maintain the insulation, insulation, sound insulation, sound absorption, heat retention, and to achieve these purposes, conventional rock wool, styrofoam, Glass wool and asbestos are mainly used.
이러한 내장재를 사용시 보온,단열,방음,흡음,보온 마감재 역할을 원활하게 수행할 수 있다는 잇점은 있으나, 각 암면,스티로폼,유리솜,석면에는 석회,규산칼륨,사문암,각섬석류,유리액 등의 화학재를 고형화 발포화시킨 제품이기 때문에 쉽게 불에 타거나 다량의 유해물질이 발생되어 인체,재산,환경에 큰 피해를 주는 단 점이 있었다.The use of these interior materials has the advantage of being able to perform the role of insulation, insulation, sound insulation, sound absorption, insulation finish smoothly, but each rock wool, styrofoam, glass wool, asbestos, lime, potassium silicate, serpentine, hornblende, glass liquid, etc. Because it is a product that solidified and foamed ash, it was easily burned or a large amount of harmful substances were generated, which had the disadvantage of causing great damage to human body, property and environment.
특히 재료의 특성상 보온,단열,방음,흡음,미장재로 사용되는 암면,유리솜은 분진,가려움증,호흡장애,발암물질을 발생시키고, 스티로폼은 화재 발생시 유해가스(cFc) 방출로 오존층에 나쁜 영향을 주며 인간의 생명과 재산을 앗아갔으며, 암면은 분진,발암물질,호흡장애 등이 동반되었다.In particular, rock wool and glass wool used as thermal insulation, insulation, sound insulation, sound absorption and plastering materials generate dust, itching, breathing disorders, and carcinogens. Styrofoam has a bad effect on the ozone layer by releasing harmful gases (cFc) in case of fire. And took human life and property, and rock wool was accompanied by dust, carcinogens, and breathing disorders.
그리고, 내장재를 건축물에 시공후 거주시에도 재료 자체에서 발생되는 환경 유해물질로 인해 거주자의 건강에 해를 끼치며 철거시에는 재활용이 안되므로 다량의 산업쓰레기가 발생되었으며, 재료 자체가 중량이기 때문에 시공이 불편하였다.In addition, even when the interior material is installed in a building, it causes harm to the health of residents due to environmental harmful substances generated from the material itself, and it is not recycled at the time of demolition, resulting in a large amount of industrial waste. It was uncomfortable.
한편, 종래의 내장재는 재료에 유해물질이 함유되어 있어 인체에 해롭고 재활용이 어려우며 불에도 약한 문제점이 있었다. On the other hand, the conventional interior materials contain harmful substances in the material is harmful to the human body is difficult to recycle and has a weak fire problem.
본 발명은 상기의 문제점을 해소하기 위하여 짚과 황토를 혼합한 내장재를 제조함으로써 내장재가 단열성,보온성,방음성,흡음성,준불연성을 가지고 내장재를 경량화하도록 하는데 있고 자연 친화적인 소재를 사용하여 인체의 유익함과 산업쓰레기에 발생되는 건축물 폐자재에도 크나큰 도움을 가질 수 있도록 하는데 그 목적이 있다. The present invention is to make the interior material light weight of the interior material having heat insulation, heat insulation, sound insulation, sound absorption, quasi-non-combustibility by manufacturing the interior material mixed with straw and loess to solve the above problems and the benefits of the human body using a natural friendly material Its purpose is to make it possible to have great help in building wastes generated by ships and industrial waste.
본 발명에 적용되는 건축물 내장재는, 짚류를 5cm의 크기로 절단하고 짚류 83 ~ 87중량%, 황토 3 ~ 7중량%, 물 8 ~ 12중량%의 비율로 혼합한 후 1500Kg/㎠ ~ 2000Kg/㎠로 가압,압출 성형 처리하여 제품을 만든 후 750℃ ~ 800℃로 순간 가열,건조 처리하여 생산하는 것을 특징으로 한다.Building interior materials applied to the present invention, after cutting the straw to the size of 5cm and mixed at a ratio of 83 to 87% by weight, 3 to 7% by weight ocher, 8 to 12% by weight of water 1500Kg / ㎠ ~ 2000Kg / ㎠ After press, extrusion molding process to make a product characterized in that the instantaneous heating, drying treatment at 750 ℃ ~ 800 ℃ to produce.
본 발명에 따르면, 짚,황토를 혼합하여 내장재를 제조함으로써 짚에서 방출되는 원적외선에 의해 건축물내의 거주공간이 쾌적해지고 황토가 준불연재 기능을 가짐으로 인해 불에도 잘 견디게 된다. 또한, 본 발명의 내장재는 보온,단열기능과 방음,흡음기능도 같이 가지게 된다.According to the present invention, by mixing straw and ocher to produce interior materials, the living space in the building is comfortable by the far-infrared rays emitted from the straw, and the ocher has a semi-incombustible function to withstand fire. In addition, the interior material of the present invention will have thermal insulation, insulation function and sound insulation, sound absorption function.

바람직하게는, 짚류 83 ~ 87중량%, 황토 3 ~ 7중량%, 물 8 ~ 12중량% 로 혼합한다. 황토는 본드 대용으로 내장재의 접착기능도 같이 가지게 된다.Preferably, it is mixed with 83-87 weight% of straws, 3-7 weight% of ocher, and 8-12 weight% of water. Ocher is also used as a substitute for bonding.
상기와 같이 일정 비율로 혼합한 후 1500Kg/㎠ ~ 2000Kg/㎠로 가압,압출 성형 처리하여 제품을 생산하여 750℃ ~ 800℃로 순간 가열,건조시켜 만드는 황토,벼짚 판넬이다. After mixing at a constant ratio as described above, the product is produced by processing by pressing and extruding molding at 1500Kg / ㎠ ~ 2000Kg / ㎠ and heated and dried at 750 ℃ ~ 800 ℃ instantaneous, straw panel.
프레스로 가압시, 판넬의 밀도를 낮게 하려면 1500Kg/㎠로 하고 판넬의 밀도를 높게 하려면 2000Kg/㎠로 한다.When pressurized, press the panel to lower the density of 1500Kg / ㎠ and to increase the density of the panel to 2000Kg / ㎠.
상기 압출,성형 후 일정한 두께와 크기로 판넬화 시켜 건축 내장재로 사용한다. 판넬의 일정 두께와 크기는 필요에 따라 만들어지는데, 예를들면 50㎝의 폭(두께)에 1m의 길이(크기)를 가지게 된다. After extrusion and molding, it is paneled to a certain thickness and size and used as a building interior material. A certain thickness and size of the panel is made as needed, for example 50 cm wide (thick) and 1 m long (size).
