Description
본 발명은 콘크리트 구조물용 수용성 수지 조성물과 이의 제조 및 이를 이용한 콘크리트 구조물 시공방법에 관한 것이다.The present invention relates to a water-soluble resin composition for a concrete structure, a method of manufacturing the same, and a method of constructing a concrete structure using the same.
일반적으로 도로 또는 교량의 표면에는 차량이 원활하게 통행할 수 있도록 포장하여 포장층이 형성되어 있다.Generally, on the surface of a road or a bridge, a packing layer is formed by packing the vehicle so that the vehicle can pass smoothly.
여기서, 상기한 포장층은 차량의 활하중을 직접 전달하는 부분으로서 이에 적합한 강도 및 균열 저항성이 있어야 한다.Here, the above-mentioned packing layer should be a portion directly transmitting the live load of the vehicle and having suitable strength and crack resistance.
또한, 상기 포장층은 눈, 비에 노출되어 있는 관계로 방수성능이 구비되어야 한다.In addition, since the packaging layer is exposed to snow and rain, waterproof performance should be provided.
이러한 도로 또는 교량 포장은 강성포장(Rigid Pavement)인 콘크리트포장과 연성포장(flexible Pavement)인 아스팔트포장이 있다.These road or bridge packages include rigid pavement concrete pavements and flexible pavement asphalt pavements.
이 중에서 시멘트를 주재료로 사용하는 콘크리트포장은 재료비가 저렴하고, 교량 등의 바닥판과 동시에 콘크리트 타설이 가능한 시공성이 우수한 장점이 있는 반면에 반복적인 차량통행에 따른 진동에 의해 콘크리트의 균열이 발생되기 쉽다.Among them, concrete pavement using cement as a main material is advantageous in that it has low cost of materials and excellent workability in which concrete can be poured simultaneously with a bottom plate of a bridge, etc., but cracks occur in the concrete due to repetitive vehicle traveling easy.
또한, 상기한 콘크리트포장의 경우에는 온도변화에 따라 수축 또는 팽창되며, 이러한 콘크리트의 수축 또는 팽창에 의해서 응력이 발생되고, 이와 같은 응력으로 인해 균열이 발생될 수 있다.Also, in the case of the concrete pavement, the concrete shrinks or expands according to the temperature change, and stress is generated due to contraction or expansion of the concrete, and cracks may be generated due to such stress.
그리고, 상기 콘크리트포장은 콘크리트의 수축 또는 팽창으로 인한 응력의 발생을 완화시키고자 일정한 간격마다 줄눈을 설치하는 경우도 있는데, 이러한 줄눈의 존재로 인하여 차량의 승차감이 떨어지는 문제가 있다.In addition, the concrete pavement may be provided with joints at regular intervals in order to alleviate the generation of stress due to shrinkage or expansion of concrete. The existence of such joints causes a problem of riding comfort of the vehicle.
이에, 상기한 바와 같은 제문제점을 해결하기 위해 등록특허 10-0869080 수지몰탈 조성물 및 상기 조성물을 이용하여 포장된 구조물이 제안되었다.In order to solve the above problems, a resin mortar composition and a packaged structure using the composition have been proposed.
상기한 종래의 수지몰탈 조성물은 (a) 제1바인더 수지로서의 우레탄 아크릴레이트 수지 및 제2바인더 수지로서의 폴리메틸 메타크릴레이트 수지를 포함하는 바인더 수지; (b) 경화제; (c) 모래; (d) 충전제로 구성된다.The above conventional resin mortar composition comprises (a) a binder resin comprising a urethane acrylate resin as a first binder resin and a polymethylmethacrylate resin as a second binder resin; (b) a curing agent; (c) sand; (d) a filler.
또한, 상기한 종래의 수지몰탈 조성물을 이용하여 포장된 구조물은 (a) 기재(substrate); (b) 상기 기재의 표면에 수지몰탈 조성물을 도포한 후에 경화시켜 형성된 포장층으로 구성된다.Also, the packaged structure using the conventional resin mortar composition described above comprises (a) a substrate; (b) a packaging layer formed by applying a resin mortar composition on the surface of the substrate and then curing.
상기한 바와 같은 구성으로 이루어진 종래의 수지몰탈 조성물 및 상기 조성물을 이용하여 포장된 구조물은 수지몰탈 조성물로서, 경화제, 모래 및 충전제 이외에 제1바인더 수지로서 우레탄 아크릴레이트 수지를 포함함으로써, 모래 입자 들 사이가 탄성 또는 유연성 있는 우레탄 아크릴레이트 수지로 결합되므로, 반복적인 차량 하중에 의한 소성변형 및 온도변화에 의한 균열의 발생을 억제할 수 있는 효과가 있다.The conventional resin mortar composition having the above-described constitution and the structure packed using the composition are resin mortar compositions which include a urethane acrylate resin as a first binder resin in addition to a curing agent, sand and filler, Is combined with an elastic or flexible urethane acrylate resin, it is possible to suppress plastic deformation due to repetitive vehicle load and occurrence of cracks due to temperature change.
그러나. 상기한 바와 같은 구성으로 이루어진 종래의 수지몰탈 조성물 및 상기 조성물을 이용하여 포장된 구조물은 콘크리트 구조물 자체에 대한 강도 및 경도는 기대 이상으로 발현되어 탁월하나, 이에 비하여 탄성력이 부족하여 탄성을 필요로 하는 부분에는 실제적으로 적용할 수 없는 문제가 있다. But.

본 발명에 따른 콘크리트 구조물용 수용성 수지 조성물은 메틸 메타크릴레이트 25∼30 중량%; 1,2-프로필렌 글리콜 디아크릴레이트 25∼30 중량%; 부틸 아크릴레이트 5∼10 중량%; 디프로필렌 글리콜 메틸 에테르 4∼5 중량%; 리튬 실리케이트 0.1∼1 중량%; 계면활성제 1∼2 중량%; 폴리카본산계 유동화제 1∼2 중량%; 물 30∼38 중량%로 구성된다.The water-soluble resin composition for a concrete structure according to the present invention comprises 25 to 30% by weight of methyl methacrylate; 25 to 30% by weight of 1,2-propylene glycol diacrylate; 5 to 10% by weight of butyl acrylate; 4 to 5% by weight of dipropylene glycol methyl ether; 0.1 to 1% by weight of lithium silicate; 1 to 2% by weight of a surfactant; 1 to 2% by weight of a polycarboxylic acid-based fluidizing agent; And 30 to 38% by weight of water.
이하, 본 발명의 구성요소를 나누어 상세히 설명한다.Hereinafter, the constituent elements of the present invention will be described in detail.
<메틸 메타크릴레이트>≪ Methyl methacrylate >
메틸 메타크릴레이트는 연성부여 및 점탄성을 개선하기 위해 사용된다.Methyl methacrylate is used to improve ductility and viscoelasticity.
상기 메틸 메타크릴레이트는 그 함량을 25∼30 중량%로 하는 것이 바람직하다.The content of the methyl methacrylate is preferably 25 to 30% by weight.
상기 메틸 메타크릴레이트의 함량이 30중량%를 초과하면 연성 및 점탄성이 개선되나 점도가 낮아져 시공성이 떨어지고 가격경쟁력이 떨어질 수 있으며, 상기 메틸 메타크릴레이트의 함량이 25중량% 미만이면 연성 및 점탄성 개선 효과가 미약할 수 있다.If the content of methyl methacrylate is more than 30% by weight, the softness and viscoelasticity are improved but the viscosity is lowered, resulting in poor workability and price competitiveness. If the methyl methacrylate content is less than 25% by weight, The effect may be weak.
<1,2-프로필렌 글리콜 디아크릴레이트>≪ 1, 2-propylene glycol diacrylate &
1,2-프로필렌 글리콜 디아크릴레이트는 유기용제의 일종으로서 단량체 성부의 중합성을 충분히 향상시키면서 용제의 함량을 낮추기 위해 25∼30 중량%를 사용함이 바람직하다.Propylene glycol diacrylate is a kind of organic solvent and it is preferable to use 25 to 30% by weight in order to sufficiently improve the polymerizability of the monomer part and lower the content of the solvent.
<부틸 아크릴레이트><Butyl acrylate>
부틸 아크릴레이트의 함량을 5∼10 중량%로 제한한 이유는 콘크리트의 안정된 인장강도를 확보하기 위한 것으로, 종래의 콘크리트의 경우 콘크리트 포장 후, 재령 28일이 경과하면 강도가 18MPa인데 비하여 본 발명의 수용성 수지로 제조된 콘크리트는 1일 경과 시에 46.08MPa, 2일 경과 52.14MPa, 3일 경과시 57.88MPa으로 월등히 높은 것을 알 수 있다.The reason for limiting the content of butyl acrylate to 5 to 10 wt% is to secure a stable tensile strength of concrete. In the case of conventional concrete, the strength is 18 MPa after aging 28 days after concrete packaging, It can be seen that the concrete made of the water-soluble resin is 46.08 MPa for one day, 52.14 MPa for 2 days, and 57.88 MPa for 3 days.
<디프로필렌 글리콜 메틸 에테르>≪ Dipropylene glycol methyl ether >
디프로필렌 글리콜 메틸 에테르는 분산, 유화력이 강하고 계면 흡착도 우수하여 폴리우레탄 원료의 혼합을 용이하게 할 수 있다.Dipropylene glycol methyl ether has a strong dispersing and emulsifying power and is excellent in interfacial adsorption, so that mixing of polyurethane raw materials can be facilitated.
상기 디프로필렌 글리콜 메틸 에테르는 4∼5 중량%로 하는 것이 바람직하며, 상기 디프로필렌 글리콜 메틸 에테르가 4중량% 보다 적을 경우에는 점도가 낮아 수용성 수지 내 혼합이 어려울 수 있고, 상기 디프로필렌 글리콜 메틸 에테르가 5% 보다 클 경우에는 수용성 수지 내 기포가 다량으로 발생할 수 있다.If the amount of the dipropylene glycol methyl ether is less than 4% by weight, the viscosity of the dipropylene glycol methyl ether may be low and mixing in the water-soluble resin may be difficult, and the dipropylene glycol methyl ether Is larger than 5%, a large amount of bubbles in the water-soluble resin may be generated.
<리튬 실리케이트><Lithium silicate>
리튬 실리케이트는 콘크리트 구조물에 침투하여 수산화칼슘과 반응하여 불용성 칼슘실리케이트 수화물을 형성할 수 있다.Lithium silicate can penetrate the concrete structure and react with calcium hydroxide to form insoluble calcium silicate hydrates.
리튬 실리케이트는 콘크리트의 조직을 보다 견고하게 하며, 콘크리트 구조물의 내구성능을 향상시키는 효과가 있다.Lithium silicate has the effect of strengthening the structure of the concrete and improving the durability of the concrete structure.
여기서, 상기 리튬 실리케이트는 0.1∼1 중량%로 함이 바람직하다.The amount of the lithium silicate is preferably 0.1 to 1% by weight.
<계면활성제><Surfactant>
계면활성제의 함량을 1∼2 중량%로 제한한 이유는 콘크리트의 경화를 촉진시키기 위한 것이다.The reason for limiting the content of the surfactant to 1 to 2 wt% is to promote curing of the concrete.
여기서, 상기한 계면활성제는 에톡실화된 노닐페닐이 대표적이다.Here, the above surfactant is ethoxylated nonylphenyl.
<폴리카본산계 유동화제><Polycarboxylic acid-based fluidizing agent>
폴리카본산계 유동화제는 120분 이상 유동성 확보, 고강도, 고유동 콘크리트에 적용, 슬럼프 플로우 손실 해결, 콘크리트 점성 슬럼프 유지, 자유 조절 가능, 사용량에 비례하여 높은 감수력 제공, 작업성 및 수밀성, 마감성 탁월, 안정된 압축강도 확보, 비교적 입형이 양호한 세척사, 망사, 하천사 사용시 작업성 및 블리딩 억제 효과 탁월, 안정된 공기포 연행을 통해 작업성 향상 및 동결 융해 저항성 증대, 친환경 재료로서 1∼2 중량%로 하는 것이 바람직하다.Polycarboxylic acid-based fluidizing agent secures fluidity for more than 120 minutes, applies to high strength, high flowable concrete, resolves slump flow loss, maintains concrete viscous slump, freely adjustable, provides high water-reducing power in proportion to usage, excellent workability and watertightness, , Securing stable compressive strength, excellent workability and bleeding suppression effect when using mesh cleaner and undergarment, good workability and freeze-thaw resistance by stable air plowing, 1 ~ 2 wt% as eco-friendly material .
특히, 폴리카본산계 유동화제로 폴리에틸렌 글리콜 술폰산 에테르 또는 폴리에틸렌 글리콜 메타크릴산을 사용하는 것이 바람직하다.Particularly, it is preferable to use polyethylene glycol sulfonic acid ether or polyethylene glycol methacrylic acid as the polycarboxylic acid-based fluidizing agent.
특히, 상기 폴리카본산계 유동화제는 고밀도 배근 콘크리트, 자기 충전형 콘크리트, 대형 고층 구조물, 60n/㎟ 고강도 고유동 콘크리트용으로 사용된다.Particularly, the polycarboxylic acid-based fluidizing agent is used for high density concrete, self-filling concrete, large high-rise structure and high-strength high-strength concrete of 60 n /
<물><Water>
물은 청수를 사용함을 원칙으로 하며, 30∼38 중량%가 바람직하다.Water is basically used with fresh water, preferably 30 to 38% by weight.
