Description

경량블록 및 그 제조방법{A light weight block and method formanufacturing the same}Light weight block and method for manufacturing the same {A light weight block and method formanufacturing the same}

본 발명은 경량블록 및 그 제조방법에 관한 것으로, 더욱 상세하게는 경량 무기소재 분말의 주원료에 결합제인 물유리, 키토산, 시멘트를 혼합하여 열처리 공정을 거치지 않고 프레스 성형하여 경량블록을 제조함으로써, 기계적 강도가 높은 경량 무기소재를 사용한 경량블록 및 그 제조방법에 관한 것이다.
The present invention relates to a light weight block and a method for manufacturing the same, and more particularly, by mixing water glass, chitosan, and cement, which are binders, in the main raw material of a light weight inorganic material powder, and manufacturing a light weight block by pressing a heat treatment without mechanically performing a heat treatment. It relates to a light weight block using a high weight lightweight inorganic material and a method of manufacturing the same.

건축물은 일반적으로 적벽돌이나 또는 시멘트 블록 등을 쌓아 건물 벽체를 시공하며, 건물의 단열성을 높이기 위해 벽체 시공시 단열재를 사용함에 따라 단열재 내외부에 중량감이 있는 블록을 이중으로 적층시켜 시공함에 따라 건축물에 가해지는 하중에 의해 벽체에 균열 등이 발생하는 문제점이 있었다.
Buildings generally build red bricks or cement blocks to build the walls of the building, and in order to increase the insulation of the building, the insulation is used to build the walls. There was a problem that a crack or the like occurred in the wall due to the applied load.

따라서, 최근에는 건축물에 가해지는 하중을 최대한 줄이기 위해 경량화시킨 벽돌이나 또는 블록의 개발이 다양하게 진행되고 있으며, 이와 같이 다양하게 개발되고 있는 경량블록에 관한 특허들을 살펴보면, 국내 등록실용신안공보 제384157호의 경량 콘크리트 블록과, 국내 등록실용신안공보 제317115호의 건축용 경량 블록 등이 알려져 있지만, 상기와 같은 블록들의 경우에는 등과 같이 블록 내부에 다수의 관통공들을 형성시켜 블록을 경량화시킴에 따라 블록의 압축강도, 휨강도 및 인장강도 등과 같은 물리적 특성이 저하할 우려가 있다.
Therefore, in recent years, various developments of lightweight bricks or blocks have been underway in order to minimize the load on buildings. Looking at the patents for lightly developed blocks, the registered Korean Utility Model Publication No. 384157 Although lightweight concrete blocks of No. 1 and light weight blocks for building of Korea Registered Utility Model Publication No. 317115 are known, in the case of the blocks as described above, a plurality of through-holes are formed in the block to reduce the weight of the blocks by making them lighter. There is a fear that physical properties such as strength, flexural strength, tensile strength, and the like deteriorate.

따라서, 상기와 같은 문제점을 해결하기 위하여, 블록 내부에 관통공들을 형성시키지 않고 섬유를 혼입하여 블록을 경량화시키는 기술이 개발되고 있으며, 관련 특허들로써, 국내 공개특허공보 제10-2005-0081782호의 강섬유 보강 시멘트 복합체와, 국내 공개특허공보 제10-2007-0120174호의 초고강도 섬유 보강 시멘트 조성물과, 국내 공개특허공보 제10-2005-0122153호의 탄소섬유보강 시멘트 복합재료 등이 공개되어 있다.
Therefore, in order to solve the above problems, a technology for lightening a block by incorporating fibers without forming through holes in the block has been developed. As related patents, steel fibers of Korean Patent Publication No. 10-2005-0081782 The reinforcing cement composite, the ultra-high strength fiber reinforcing cement composition of JP 10-2007-0120174, the carbon fiber reinforcing cement composite material of JP 10-2005-0122153, etc. are disclosed.

하지만, 상기와 같은 기술의 경우, 콘크리트의 취성파괴 등을 방지하기 위해 일반 콘크리트의 배합에 강섬유 및 유기섬유 등을 혼입하여 제조하는 섬유 보강 콘크리트(fiber reinfored concrete)로써, 일반 콘크리트의 배합에 섬유를 투입하므로 콘크리트의 점성 부족으로 섬유를 다량으로 투입하지 못하여 만족할 만할 인성을 확보하지도 못할 뿐더러, 섬유 뭉침(fiber ball) 현상이 발생하여 오히려 콘크리트의 성능을 저하시키는 경우도 발생하고 있다.
However, in the case of the above technique, in order to prevent the brittle fracture of the concrete, such as fiber reinfored concrete manufactured by mixing steel fibers and organic fibers in the mixing of the general concrete (fiber reinfored concrete), Due to the low viscosity of the concrete, a large amount of fiber could not be added and sufficient toughness could not be secured. Also, a fiber ball phenomenon occurred and the performance of the concrete was deteriorated.

또한, 섬유 혼입으로는 고강도 콘크리트의 취성파괴를 완전히 방지하지 못하여, 지진 또는 차량의 반복 및 충격하중, 화재 및 자연 열화현상 등이 발생하였을 때 곧바로 구조물이 파괴되는 등 기계적 강도와 같은 물리적 특성에 여전히 취약점을 안고 있다.
In addition, fiber incorporation does not completely prevent brittle fracture of high-strength concrete and is still affected by physical properties such as mechanical strength, such as structural destruction immediately after an earthquake, repetitive and impact load of a vehicle, fire, and natural deterioration. It has a vulnerability.

따라서, 본 발명은 상기와 같은 문제점들을 해결하기 위한 방안으로 경량 무기소재 분말인 진주석 및 규회석에 결합제인 물유리, 키토산, 시멘트를 혼합하여 열처리 공정을 거치지 않고 프레스 성형하여 경량블록을 제조함으로써, 기계적 강도가 높은 경량 무기소재를 사용한 것을 특징으로 하는 경량블록을 제공함을 과제로 한다.

The lightweight inorganic material powder used in the present invention is an inorganic material powder for reducing the weight of the block, and the mixing amount of the lightweight inorganic material powder is preferably 40 to 60% by weight. When the mixed amount of the lightweight inorganic material powder is less than 40% by weight, it is difficult to expect the improvement of the mechanical strength such as the compressive strength, the bending strength, the tensile strength, and when the mixed amount of the lightweight inorganic material powder exceeds the 60% by weight, the specific gravity is high. In addition, it is not possible to manufacture a lightweight block due to the increase in price competitiveness is disadvantageous that can be used only in some special fields.

The pearlite has a function of reducing the weight while improving the mechanical strength of the lightweight block, and when the mixing amount of pearlite is less than 45% by weight, the effect of improving the mechanical strength is insufficient, and when the mixing amount of the pearlite exceeds 55% by weight There is a disadvantage that uniform mixing with the binder to be described later becomes difficult.

또한 규회석은 경량블록의 기계적 강도를 향상시키면서도 경량화시키는 기능을 하며, 규회석의 혼합량이 45 중량% 미만이 될 경우에는 기계적 강도의 향상 효과가 미비하며, 규회석의 혼합량이 55 중량%를 초과할 경우에는 후술되어질 결합제와의 균일한 혼합이 어려워지는 단점이 있다.
In addition, the wollastonite functions to reduce the weight while improving the mechanical strength of the lightweight block.If the wollastonite mixture is less than 45 wt%, the effect of improving the mechanical strength is insignificant, and the wollastonite mixture exceeds 55 wt%. There is a disadvantage that uniform mixing with the binder to be described later becomes difficult.

And in the present invention, the water glass has a function to improve the bonding, heat resistance, film formation and adsorption properties, the mixing amount of the water glass is preferably 15 to 25% by weight. When the mixing amount of the water glass is less than 15% by weight, the above function cannot be expressed. When the mixing amount of the water glass exceeds 25% by weight, moldability and workability are inferior.

그리고 본 발명에서 상기 키토산은 결합성, 조막성 및 흡착성을 향상시킬 뿐만 아니라 항균, 방충 기능을 하며, 키토산의 혼합량은 25~35 중량%인 것이 바람직하다. 키토산의 혼합량이 25 중량% 미만이 될 경우에는 상기 기능을 발현시킬 수 없으며, 키토산의 혼합량이 35 중량%를 초과할 경우에는 성형 및 작업성이 떨어지는 단점이 있다.
And in the present invention, the chitosan not only improves the binding, film formation and adsorption, but also has an antibacterial and insect repellent function, and the mixing amount of chitosan is preferably 25 to 35% by weight. If the mixing amount of chitosan is less than 25% by weight can not express the function, when the mixing amount of chitosan exceeds 35% by weight has a disadvantage of poor moldability and workability.
