Description
본 발명은 자연 환원형 황토 몰탈 조성물 및 이를 이용한 포장재 시공방법에 관한 것으로, 좀 더 구체적으로는 종래의 시멘트 몰탈이 다량의 알칼리 발생 및 라돈과 같은 유해물질 방출로 인체 및 환경에 유해한 작용을 하고, 폐기시 환경오염 문제를 일으킬 수 있었던 것과는 대조적으로, pH 5~8 범위의 약산성 내지 중성을 나타내고 폐기시 자연으로 환원될 수 있어서 인체 및 환경에 무해하며, 기존 시멘트 몰탈의 강도를 상회하는 고강도 및 노크랙의 우수한 물성을 가질 뿐 아니라, 원적외선 방사, 단열, 보온, 습도조절 등의 다양한 기능성을 갖는 자연 환원형 황토 몰탈 조성물 및 그것을 이용한 포장재의 시공방법에 관한 것이다.The present invention relates to a natural reducing type ocher mortar composition and a method for constructing a packaging material using the same, and more specifically, conventional cement mortar has a harmful effect on human body and environment by generating a large amount of alkali and releasing harmful substances such as radon, In contrast to wastes that could cause environmental pollution problems, it is harmless to humans and the environment because it is weakly acidic to neutral in the pH range of 5 to 8 and can be reduced to nature when disposed of. In addition to having excellent crack properties, the present invention relates to a natural reducing type ocher mortar composition having various functionalities such as far-infrared radiation, heat insulation, thermal insulation, humidity control, and a method for constructing a packaging material using the same.
종래 건축물 미장용 몰탈이나 인도용 도로에 대한 포장재로서 사용되던 시멘트 몰탈은 포틀랜드 시멘트 또는 3종 시멘트(조강 포틀랜드 시멘트), 고로 슬래그 미분말, 마이크로 시멘트, 백시멘트 등을 이용한 것으로, 이들은 다량의 알칼리를 발생하고 라돈과 같은 물질을 장기간 방출하여 인체에 유해한 작용을 하는 것으로 밝혀졌으나, 워낙 오래전부터 범용으로 사용되어 왔기 때문에 현재도 여전히 고화제로서 널리 사용되고 있다.Cement mortar, which has been used as a paving material for building plastering or sidewalks in the past, uses portland cement or three kinds of cement (crude steel portland cement), blast furnace slag powder, micro cement, and back cement, which generate a large amount of alkali. It has been found to have a harmful effect on the human body by releasing a substance such as radon for a long time, but it is still widely used as a solidifying agent since it has been widely used for a long time.
다만, 종래의 시멘트 몰탈 대신 해초 추출물이나 우레탄과 같은 고화제(경화제)를 사용하여 시멘트 몰탈의 문제점을 극복하고자 하는 시도가 있었으나, 강도와 내구성 면에서 종래의 시멘트 몰탈 보다 현저히 떨어지고, 겨울철 혹한기에 동파되거나 들뜸 현상 및 크랙이 생겨 실제로 적용되기에는 한계가 있었다.However, there has been an attempt to overcome the problems of cement mortar by using a seaweed extract or a solidifying agent (hardener) such as urethane instead of conventional cement mortar, but in terms of strength and durability, it is significantly lower than that of conventional cement mortar and freezes in cold weather in winter. Or lifting and cracking, there was a limit to the practical application.
또한, 이들 종래의 시멘트 몰탈 및 대체품은 폐기시 재생 또는 재활용이 불가능하여 환경오염의 문제가 있었으므로, 이를 보완하기 위하여 토양이나 황토를 이용한 포장공법이나 몰탈 조성물이 개발되었다.In addition, these conventional cement mortar and substitutes were not possible to be recycled or recycled at the time of disposal, there was a problem of environmental pollution, in order to compensate for this, a packaging method or mortar composition using soil or loess has been developed.
먼저, 국내 특허 제272800호(2000. 11. 15. 공고)는 도로포장을 위해 노상을 정비하는 공정; 도로의 사용목적에 따라 노상의 상단부에 보조기층 또는 쇄석기층을 일정 두께로 포설하는 공정; 상기 보조기층 또는 쇄석기층의 상단부에 골재 최대치수가 25㎜, 13㎜ 및 6㎜로 이루어진 군에서 선택된 골재 1㎥, 상기 골재 1㎥ 당 시멘트 200-400㎏, 물 80-130㎏, 시멘트 중량 기준으로 감수제가 0.1-2% 포함되고 공극율이 8-30%가 되는 다공성 콘크리트 혼합물을 포설, 다짐한 후 1일 이상 양생하는 공정; 및 상기 콘크리트층 상단부에 4㎜체에서 90% 이상 통과하고 #200 체에서 80% 이하 통과되는 토양에 바인더로서 아크릴, 우레탄, 에폭시 및 불포화 수지로 이루어지는 군에서 선택된 수지 용액 또는 에멀젼을 토양 1 중량부 기준으로 수지용액 또는 에멀젼 0.05-1 중량부를 혼합한 토양층을 포설하고 1일 이상 양생하 는 공정을 포함하는 토양도로 포장방법을 개시하였다.First, Korean Patent No. 272800 (August 15, 2000) discloses a process of maintaining a roadbed for paving roads; Laying an auxiliary layer or a crusher layer in a predetermined thickness on the upper end of the road according to the purpose of use of the road; Maximum aggregate size of aggregate at the upper end of the auxiliary base layer or the crusher layer is 25㎜, 13㎜ and 6㎜ aggregate selected from the group consisting of, 200-400kg of cement per 1㎥ of the aggregate, water 80-130㎏, cement weight Laying a porous concrete mixture containing 0.1-2% water reducing agent and having a porosity of 8-30% and curing it for at least one day; And 1 part by weight of a resin solution or emulsion selected from the group consisting of acrylic, urethane, epoxy, and unsaturated resins as a binder in the soil that passes 90% or more in a 4 mm sieve and 80% or less in a # 200 sieve. A soil road pavement method including a process of laying a soil layer mixed with 0.05-1 parts by weight of a resin solution or an emulsion and curing for at least one day was disclosed.
상기 특허에서 개시된 방법은 흙길이 갖는 자연친화성, 부드러운 감촉 등을 제공할 수 있다는 장점을 갖지만, 토양층을 포설하기 전에 시멘트를 포함하는 콘크리트층을 형성함으로써 시멘트 사용으로 인한 유해성 및 폐기시의 환경 오염 문제는 여전히 남게 된다.The method disclosed in the above patent has the advantage of providing natural affinity, soft texture, etc. of the dirt road, but by forming a concrete layer containing cement before laying the soil layer, the harmful effects of the use of cement and environmental pollution during disposal The problem remains.
한편, 일반 토양 대신 황토를 이용한 포장재와 관련된 종래 기술로서, 국내 특허 제408594호(2003. 12. 6. 공고)는, 압축강도를 높이기 위하여 황토를 구워 100∼150 메쉬로 분쇄한 고순도 미세 분말 황토를 사용하며 시멘트와 황토의 배합 중량비가 1 : 0.78∼1.42이고 천연 황토색을 발현시키기 위하여 붉은색과 노란색의 산화철을 조합하여 시멘트량에 대하여 2.67∼5.50%를 첨가 혼합하고, 이 혼합물에 자갈, 모래, 물을 혼합하되 도로의 용도에 따라 시멘트에 대한 황토의 배합비와 산화철의 첨가비를 조절하여 제조하는 것을 특징으로 하는 황토 도로포장재의 제조방법을 개시하였다.On the other hand, as a prior art related to packaging materials using ocher instead of ordinary soil, Korean Patent No. 408594 (Dec. 6, 2003) discloses high-purity fine powder loess, which is baked and ground to 100-150 mesh in order to increase the compressive strength. The mixture weight ratio of cement and loess is 1: 0.78 ~ 1.42, and red and yellow iron oxides are combined to add 2.67 ~ 5.50% by weight of cement in order to express natural ocher color. The present invention discloses a method for manufacturing ocher road pavement, which is prepared by mixing water, but adjusting the mixture ratio of loess to cement and the addition ratio of iron oxide according to the purpose of the road.
또, 국내 특허 제632699호(2006. 10. 11. 공고) "흙 연질포장용 조성물과 이를 이용한 흙 연질 포장공법"은 슬래그 미분말 55∼65 중량%, 천연 무수석고 35∼45 중량%를 혼합하여 연질파우더를 생성하고, 체거름된 마사토 100 중량부에 상기의 연질파우더 6 내지 12 중량부를 첨가 교반하여 연질파우더 혼합물을 형성하며, 상기 연질파우더 혼합물에 첨가제(에틸하이드록시 에틸셀룰로오스) 1 내지 6 중량부를 첨가하여 건식혼합시킨 다음, 물 12 내지 15 중량부를 첨가 및 교반하여 흙 연질포장용 조성물을 형성하고, 상기 혼합 교반된 흙 연질포장용 조성물을 소정 두 께로 포설하며, 이를 로울러로 반복 다짐 및 양생하여 pH 8.5∼9.5, 강도 4∼10㎏F/㎠ 를 구비하는 것을 특징으로 하는 흙 연질 포장공법을 개시하였다.In addition, Korean Patent No. 632699 (announced on October 11, 2006) "Soil soft packaging composition and soil soft packaging method using the same" is soft by mixing 55 to 65% by weight of slag fine powder, 35 to 45% by weight of natural anhydrous gypsum A powder is produced, and 6 to 12 parts by weight of the above soft powder is added to 100 parts by weight of sieved masato and stirred to form a soft powder mixture, and 1 to 6 parts by weight of an additive (ethylhydroxy ethyl cellulose) is added to the soft powder.

It is composed.
본 발명의 조성물은 황토색 또는 적색의 안료를 더 포함할 수 있다.The composition of the present invention may further comprise a pigment of ocher or red.
상기 조성물의 각 성분들은 분말 형태로 사용되며, 각 분말의 입자 크기는 상기 황토분말이 10-300 메쉬, 상기 모래가 10-100 메쉬, 상기 벤토나이트분말이 80-200 메쉬, 상기 팽창성 혼합재 분말이 100-200 메쉬, 상기 무수 석고분말이 100-200 메쉬, 상기 구연산분말이 30-50 메쉬, 상기 비닐아세테이트 공중합수지가 50-100 메쉬 범위에 있고, 상기 천연셀룰로오스 섬유는 0.2-0.5mm의 길이를 갖는다. Each component of the composition is used in powder form, the particle size of each powder is 10-300 mesh of the ocher powder, 10-100 mesh of the sand, 80-200 mesh of the bentonite powder, 100 of the expandable mixture powder -200 mesh, the dry gypsum powder is 100-200 mesh, the citric acid powder is 30-50 mesh, the vinyl acetate copolymer resin is in the range of 50-100 mesh, the natural cellulose fiber has a length of 0.2-0.5mm .
상기에서 균열 방지용 팽창성 혼합재는 CSA(칼슘설포알루미네이트, calcium sulfoaluminate), 비결정질 CA(칼슘알루미네이트, calcium aluminate) 또는 이들의 혼합물을 사용하는 것이 바람직하다.In the above-mentioned expansion preventing material for preventing cracks, it is preferable to use CSA (calcium sulfoaluminate), amorphous CA (calcium aluminate, calcium aluminate) or a mixture thereof.
상기에서 황토 및 모래는 0.05% 이하, 구체적으로는 0.001-0.05%의 수분 함량을 갖도록 건조된 것을 이용한다. In the above, ocher and sand are dried to have a water content of 0.05% or less, specifically 0.001-0.05%.
상기에서 황토는 황토 흙을 건조로에서 200-500℃의 스팀 열로 약 20분간 건조시킨 후 약 5분간 직접 열을 가하여 건조 살균시키고, 이를 밀로 갈아서 입도 10-300 메쉬 통과분을 자동 스크린 채망을 이용하여 걸러낸 것을 이용하는데, 본 발명의 경우 일반 황토보다 고령황토를 이용하는 것이 효과면에서 훨씬 바람직하다. In the above, the ocher is dried for about 20 minutes by steam heat of 200-500 ° C. in a drying furnace, and then dried and sterilized by direct heat for about 5 minutes. In the present invention, it is much more preferable to use aged ocher than general loess.
즉, 황토는 일반적으로 원적외선 방사, 탈취, 단열, 습도조절, 자정력 등이 우수한 것으로 알려져 있으나, 고령황토는 일반 황토보다 입자가 곱고 산소 함유량이 높으며, 고령황토 1g에는 2억 마리 이상의 미생물이 살고 있어 다양한 효소들이 복합적으로 순환 작용을 하여 해독력과 흡수력, 자정력이 뛰어나고 인체에 유익한 음이온과 원적외선을 방출하는 친환경 무독성의 재질로서, 본 발명의 목적 면에서 더욱 바람직한 성분이라 할 수 있다.In other words, loess is generally known to have far-infrared radiation, deodorization, heat insulation, humidity control, and self-cleaning ability.
