무공해 건축자재용 소재 및 그 제조방법{The chemical-free bulding materials and it`s manufacturing method}Chemical-free bulding materials and it`s manufacturing method

본 발명은 건축자재용 소재를 환경친화적인 식물성 섬유입자로 대체하여 인체에 무해하고, 폐기시 공해가 없을 뿐만 아니라 사료나 유기질비료로 재활용할 수 있는 무공해 건축자재용 소재 및 그 제조방법에 관한 것이다.The present invention relates to an environmentally friendly building material and a method of manufacturing the same, which are harmless to the human body by replacing the building material with environmentally friendly vegetable fiber particles, and which can be recycled as feed or organic fertilizer as well as being free from pollution when disposed of. .

일반적으로 건축자재들은 목재나, 금속, 콘크리트 및 합성수지(플라스틱)등을 사용한다. 그 중 합성수지는 각종 대량의 환경호르몬 및 중금속 등과 같이 인체에 해가되는 각종 유해물질을 내포하고 있다. 이러한 소재들은 폐기시 자연분해가 되지 않고 또 재활용이 어려운 단점이 있다. 따라서 대부분 소각처리를 하게 되는데, 소각시 많은 다이옥신과 같은 맹독성 유해물질들을 방출하기 때문에 역시 처리에 어려움을 겪고 있으며, 그 처리비용도 많이 소요되는 폐단이 있다.In general, building materials use wood, metal, concrete and plastic (plastic). Among them, synthetic resins contain various harmful substances such as various environmental hormones and heavy metals that are harmful to the human body. These materials do not decompose naturally and are difficult to recycle. Therefore, most of the incineration process, because it emits a lot of toxic harmful substances such as dioxin during incineration, also difficult to treat, there is a waste disposal costly.

본 발명은 이러한 종래의 문제점을 해소하기 위하여 창안한 것으로서, 그 목적은 환경호르몬이나 중금속 및 다이옥신 등과 같이 인체에 해롭고 자연을 파괴하는 공해물질을 포함하지 않고, 또 매립시 생분해처리가 되고, 소각시 공해물질이없는 등 폐기처리시에 발생하는 2차공해가 없고, 성형성, 내구성, 견고서 및 내부식성 등 건축자재가 요구하는 성질을 충분히 만족시킬 수 있을 뿐만 아니라 안전하고 환경친화적인 무공해 건축자재용 소재를 제공하는데 있다. 특히 이러한 신소재를 대량생산할 수 있는 제조방법을 제공하는데 있다.The present invention was devised to solve such a conventional problem, and its object is not to contain environmentally harmful substances such as environmental hormones, heavy metals, and dioxins, which are harmful to the human body and destroy nature, and are biodegradable when landfilled, There is no secondary pollution generated during disposal, such as no pollution, and it can satisfy the properties required by building materials such as formability, durability, firmness and corrosion resistance, and it is safe and environmentally friendly It is to provide the dragon material. In particular, it is to provide a manufacturing method that can mass-produce these new materials.

상기 목적을 달성하기 위한 본 발명은, 식물섬유입자 즉, 각종 식물종피(옥수수피, 대두피, 벼껍질, 볏짚, 옥수수봉, 옥수수대 등)를 기본원료로 하고, 일정량의 곡물전분과 식용성 성형교 즉, 아교와 같은 접착제, 준분교, 골교(동물의 뼈에서 채취한 교) 등을 첨가제로 구성된다.The present invention for achieving the above object, the plant fiber particles, that is, a variety of plant seeds (corn bark, soybean hull, rice husk, rice straw, corn bar, corn bar, etc.) as a basic raw material, a certain amount of grain starch and edible Molded bridges, that is, adhesives such as glues, semi-branched bridges, bone bridges (bridges taken from animal bones), etc., are composed of additives.

이러한 본 발명 제조방법은 옥수수피, 대두피, 옥수수봉, 옥수수대, 왕겨, 볏짚 등 식물섬유입자를 20-200메쉬로 분쇄한 후 그 중량의 10%-40%되는 성형교를 넣고, 교중량의 1-5배의 물을 넣고 혼합기로 혼합하면서 일정량의 염산, 초산, 유산 등 산으로 ph 4-6.5가 되도록 조절한다.Such a method of manufacturing the present invention is pulverized plant fiber particles, such as corn bark, soybean hull, corn rods, corn bran, rice husk, rice straw, 20-200 mesh, and put the forming bridge is 10% -40% of the weight, bridge weight Add 1-5 times of water and mix with a mixer to adjust pH 4-6.5 with a certain amount of acid, hydrochloric acid, acetic acid and lactic acid.

이와 같이 혼합된 원료를 크롬도금한 특정 형태의 제조금형에서 80℃-250℃의 온도 80kg-250kg/cm2로 2-200초 동안 압축시켜 성형한 후 건조하여 완성한다.The mixed raw materials are compressed in a specific shape of the production mold chromium plated at a temperature of 80 kg-250 ° C. at 80 kg-250 kg / cm 2 for 2 to 200 seconds, and then dried to complete.

한편, 사출성형시 또 다른 방법으로서 제조의 수요에 따라 먼저 2차 왕래식 사출기에 일정한 비례로 잘 혼합된 원료를 주입하면서 사출하되 원료가 금형에 넣기 전에 사출기 내에서 충분히 가열된 상태에서 수분을 증발시키면서 사출한다. 사출된 성형용 원자재가 수분함량이 20%-40%로부터 10%-14%로 감소되는 환경상태에서 즉시 장방형이나 원형금형 등 임의의 금형에 즉시 사출시켜 성형하고 건조시킨다.그 건조된 제품은 한 번에 성형되므로 표면이 깔끔하고 마감처리가 간단하다.On the other hand, in injection molding, as a method of manufacturing, first, a well-mixed raw material is injected into the secondary combustor in a constant proportion according to the demand of manufacturing, but the water is evaporated while being sufficiently heated in the injection machine before the raw material is put into the mold. While injecting. The injected molding raw material is immediately injected into an arbitrary mold such as a rectangle or a circular mold and molded and dried in an environment where the moisture content is reduced from 20% -40% to 10% -14%. Molded in one time, the surface is clean and easy to finish.

본 발명의 소재를 이루는 옥수수껍질이나 대두피는 옥수수전분공장이나 대두 단백제조공장에서 전분과 대두단백 이외의 부산물로 분류하고, 분류된 부산물에서 이물질을 제거한 후 상술한 제조방법에 따라 제조하여 소재를 제공한다.Corn hulls or soybean hulls forming the material of the present invention are classified as by-products other than starch and soy protein in corn starch plant or soybean protein manufacturing plant, and remove the foreign matters from the classified by-products and then prepared according to the manufacturing method described above to provide a material. do.

그 소재에 여러 가지 색상을 출연하고 여러 가지 표면무늬를 양각할 수 있는 금형에서 도안과 색상이 다른 제품 등 다양한 형태의 건축자재(문틀, 문짝 등)를 압출 또는 사출성형할 수 있다.Various types of building materials (door frames, doors, etc.), such as products with different patterns and colors, can be extruded or injection-molded from molds capable of appearing various colors on the material and embossing various surface patterns.

한편, 본 발명의 소재를 발포성형시에는 발포 가마에 믹싱한 재료를 넣고 200℃∼1000℃ 외부 가온상태에서 가마내부의 압력이 3∼9대기압 압력까지 온도와 압력을 올리다가 순간적으로 상온과 1대기압 상태로 발포시키면서 습도를 조절하여 성형시키고 환충제인 경우에는 기하적 크기를 별도 공정으로 성형한다.On the other hand, during the foam molding of the material of the present invention, the mixed material is put into a foaming kiln, and the temperature inside the kiln is raised to a temperature of 3 to 9 atmospheric pressure under 200 ° C to 1000 ° C of external heating, It is molded by controlling the humidity while foaming at atmospheric pressure, and in the case of a repellent, the geometric size is molded in a separate process.
