본 발명은 도로 구조물의 내염 성능을 보강하고, 포장도로의 예방적 유지보수를 위해 개질 유황 초속경 시멘트 분말에 다양한 색상 변화 가능한 아크릴 에멀젼 바인더의 제조방법 및 스프레이 분사 시공 방법에 관한 것으로서, 보다 자세하게 설명하면, 나노 미터 크기의 유황 입자(Powder)를 포함하는 무기계 결합제에 스티렌-아크릴산 공중합체의 에멀젼 바인더를 혼합하여, 중앙분리대나 방호벽 등의 도로 구조물이나 아스팔트 콘크리트 또는 시멘트 콘크리트 도로의 보수 구간에 적용함으로써 내염성, 내화학성을 보강하고, 표면 코팅에 따른 방수 효과와 굴곡 강도 및 내후성, 미끄럼 저항성능 등을 향상시킬 수 있으며, 구조물과 포장체의 공용성을 증대시킬 수 있는 나노 개질 유황을 포함한 유지보수 예방제 조성물 및 이를 사용한 스프레이 분사 방식의 유지/보수 예방 시공 방법에 관한 것이다.The present invention relates to a method for manufacturing an acrylic emulsion binder capable of various color changes in a modified sulfur-sulfur quick-curing cement powder for reinforcement of flame retardancy of a road structure and preventive maintenance of a pavement, and a spray spraying method. , An emulsion binder of a styrene-acrylic acid copolymer is mixed with an inorganic binder containing nanometer-sized sulfur powder and applied to a road section such as a center separator or a barrier wall or a repair section of an asphalt concrete or cement concrete road A maintenance preventive composition including nano-modified sulfur which can enhance the water resistance, bending strength, weather resistance, slip resistance performance and the like of the surface coating by reinforcing the flame retardancy and chemical resistance, and enhancing the compatibility of the structure and the package And a spraying chamber using the same The present invention relates to the maintenance / preventive maintenance construction method.

최근 국내 포장도로 구조물은 교통량 및 중차량의 증가로 반복되는 교통 하중과 급격한 기후 변화 조건에 직접 노출되어 파손이 빈번해짐에 따라 보수 또는 재포장 시기가 점점 단축되고 있다.Recently, domestic pavement structures have been shortened in repair or repacking time due to frequent breakage due to direct exposure to repeated traffic loads and rapid climate change conditions due to increase in traffic volume and heavy vehicles.

우리나라의 경우는 일반 국도에서 연간 전체 포장도로 유지 보수 예산의 5%를 예방적 유지 보수 공법에 편성하고 있고, 사전적 보수 개념이 중요하다는 인식이 증가하고 있으나, 교통량이 많고 연간 기후 변화가 심해서 포장도로의 조기파손이 심한 도심지의 경우는 여전히 예방적 유지보수 공법 적용이 활성화되지 않고 있다.In Korea, 5% of the total pavement maintenance budget is organized in preventive maintenance method in the national highway, and the awareness that the concept of advance compensation is important is increasing. However, since the traffic volume is high and the annual climate change is severe, In the case of urban areas where the roads are severely damaged early, the application of preventive maintenance methods is not yet activated.

포장도로 파손의 주요 원인으로, 크게 구조적 요인에 의한 손상, 포장 재료 불량, 시공 불량 등에 의한 손상 등으로 분류할 수 있다. 국내의 노후 도로 및 일반 도로의 유지보수 공법은 단순히 파손된 부위만을 메우는 균열 실링, 균열 충진 또는 도로가 깊게 파인 곳을 메우는 소파 보수 등으로 이루어지고 있다.The main cause of pavement damage can be classified as damage caused by structural factors, defective packaging materials, poor construction, and the like. Maintenance methods of old roads and general roads in Korea consist of crack sealing, crack filling or sofa repair to fill only the broken parts.

포트홀(Pot Hole) 보수는, 구멍이 파인 도로를 빗자루 또는 블로워 장비를 사용하여 먼지나 이물질을 제거한 뒤, 상온 패킹 재료를 포설하는 방법으로 이루어지며, 시공이 용이하고 즉시 교통 개방이 가능한 장점이 있으나, 시간이 경과함에 따라 포장도로 표면과의 접착력 저하로 인해 포설된 상온 패킹 재료가 박리되는 현상이 자주 발생하고, 포설된 형태가 덧붙인 모양을 하고 있어 전체적으로 외관이 좋지 아니하므로 주로 임시방편으로 사용되고 있다.Pot Hole maintenance is a method of removing dust or foreign matter by using a broom or blower equipment on the road with holes and then installing a packing material at room temperature. It is easy to construct and can open traffic immediately Temperature packing material is often peeled due to deterioration of adhesion with the surface of the pavement as time elapses and the shape of the packed material is added so that the appearance is not good overall so that it is mainly used as a temporary measure .

그리고 균열 실링(Crack sealing)의 핫-멜트(Hot-Melt) sealant를 사용한 보수 공법은, 도로의 균열 부위만을 절삭하여 Hot-Melt 재료를 이용 Sealing 하는 방법으로 초기 균열에는 효과적이지만 균열 부위가 너무 넓은 도로에 사용이 곤란하고 평탄도 및 외관상 문제가 있으며, 재료를 가열해야 하므로 가열장치가 추가로 더 필요하고, 이러한 가열 과정 중에서 대기로 유해성 물질이 발생할 수 있다.The repair method using the hot-melt sealant of the crack sealing is a method of cutting only the crack part of the road and sealing it using the hot-melt material. It is effective for the initial crack, but the crack part is too wide It is difficult to use on the road, there is a problem in flatness and appearance, the material needs to be heated, and furthermore, a heating device is further required, and harmful substances may be generated in the atmosphere during the heating process.

이러한 응급 보수 및 소파 보수의 경우는, 도로 미관 훼손과 평탄성 확보의 어려움으로 인해, 자동차 운행의 안정성 감소 및 소음의 증가에 따른 지속적인 민원 발생 등의 문제점이 존재하기 때문에, 포장도로의 파손 정도에 상관없이 막대한 비용이 발생하는 절삭 후 덧씌우기 또는 덧씌우기 공법을 적용하고 있다. 이러한 절삭 후 덧씌우기 또는 덧씌우기 공법은 도로의 파손이 많이 진행된 후에나 가능하고, 비용 절감 효과 및 시공의 신속성 측면에서는 바람직하지 않은 보수 공법이다. In the case of such emergency repair and sofa repair, there is a problem such as a decrease in the stability of the automobile operation and a continuous complaints due to the increase of noise due to the difficulty in securing the road aesthetic appearance and flatness, The overlay or overlay method is applied after the cutting, which causes a great cost. The overlaying or overlaying method after cutting can be performed after the breakage of the road has progressed much, and it is an undesirable maintenance method in terms of cost reduction and quickness of construction.

등록특허 제1344366호(예방적 유지보수를 위한 아스팔트 씰코팅재 및 이를 이용한 시공방법)는 개질 아스팔트 바인더에 유화수를 첨가하여 유화 개질 아스팔트로 변화시키는 방법으로, 가열방식이 아니기 때문에 공해 물질이 발생하지 않고 상온 시공 가능한 장점을 갖고 있지만, 유화 아스팔트를 바인더로 사용할 시 골재와 바인더의 응집력이 약하므로 포장체의 내구성이 떨어지고, 이로 인한 골재 입자의 탈리 또는 혼합물의 마모 손실 등이 발생하며, 양생 기간이 길어 빠른 교통 개방이 어려운 단점이 존재한다.No. 1344366 (an asphalt seal coating material for preventive maintenance and a construction method using the same) is a method in which emulsified water is added to a modified asphalt binder to change into an emulsified modified asphalt. Since it is not a heating method, However, when the emulsified asphalt is used as a binder, the cohesive force of the aggregate and the binder is weak, so that the durability of the package is deteriorated. As a result, the aggregate particles are separated or the wear loss of the mixture occurs. There is a drawback that it is difficult to open traffic quickly.

또한, 등록특허 제0944825호에 제시된 가열식 박층 포장재 및 이를 시용한 도로의 박층 포장방법과 등록특허 제1114238호에서 언급하고 있는 도로포장의 줄눈, 크랙 보수재 및 이를 사용한 보수방법은, 에틸렌비닐아세테이트(EVA)를 주원료로 사용하고, 개질재와 기타 합성수지를 포함하는 제품으로, 제품의 접착성능과 강도 측면에서는 물성이 우수한 장점이 있으나, 제품을 용융하여 살포하기 위해서는 높은 온도로의 가열과 시공이 이루어져야 하므로, 작업시 가열장비를 사용해야만 하고, 많은 탄소배출 특성을 갖는 등의 문제점이 여전히 존재한다.In addition, the heating laminate packaging material disclosed in the registered patent No. 0944825, the thin layer packing method of the road using the same, and the jointing and crack repairing materials of the road pavement and the repairing method using them are disclosed in EP-A-1114238, ) Is used as the main raw material, and it is a product containing a modifier and other synthetic resin, and has excellent physical properties in terms of adhesive performance and strength of the product. However, in order to melt and spray the product, , There is still a problem such as having to use heating equipment in operation and having many carbon emission characteristics.

또한, 등록특허 제0719853호는 상온 습기 경화형 폴리우레탄 바인더 조성물과 이를 이용한 도로보수용 아스팔트 보수재 및 그의 제조방법을 제시하고 있고, 우레탄을 이용한 보수재를 통해 강도와 부착성능이 우수할 뿐만 아니라 시공방법이 상온이므로 간편하다는 장점을 갖고 있다. 하지만, 제품의 생산 중 습기와의 차단이나 포장 시 질소 주입 등이 어려운 점이 있으며, 제품포장 파손 시 제품이 경화되는 문제점을 가지고 있다. In addition, Patent No. 0719853 discloses a room temperature curing type polyurethane binder composition, a road repair asphalt repairing material using the composition, and a method of manufacturing the same. In addition to excellent strength and adhesion performance through a repair material using urethane, It has the advantage of being simple because it is room temperature. However, it is difficult to block moisture from the product during production and to inject nitrogen at the time of packaging, and there is a problem that the product is hardened when the package is broken.

pH조절제는 0.01~5 중량부의 범위로 사용하여 pH를 9 내지 10의 범위로 조절하는 것이 바람직하다. pH가 너무 높을 경우에는 안정성이 떨어지고, 여분의 염분에 의해 가수분해가 일어나기 쉬우며, 너무 낮을 경우에는 부패하기 쉽다. The pH adjusting agent is preferably used in the range of 0.01 to 5 parts by weight and the pH is preferably adjusted to the range of 9 to 10. When the pH is too high, stability is poor, hydrolysis is apt to occur due to extra salt, and if it is too low, it is likely to become rotten.

It is preferable that 0.1 to 10 parts by weight of the acrylic emulsion resin is contained in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the acrylic emulsion resin, It is necessary to appropriately control the amount of use seasonally, since it is possible to impart a tackiness to the surface when the amount is high (that is, when it is used at the level of the amount used in winter).

본 발명의 포장도로의 유지보수 예방제 조성물을 사용하여 스프레이 분사 방식으로 시공 할때, 상기 액상 바인더와 혼합되어 사용되는 무기계 결합제는, 보통 포틀랜트 시멘트 30~70 중량%, 이산화규소 10~30 중량%, 알루미나 0.1~15 중량%, 칼슘설포알루미네이트 0.1~15 중량%, 석고 10~30 중량%, 고로슬래그 0.1~10 중량% 및 나노 입자인 유황 분말 0.01~10 중량%를 포함하는 것이 바람직하다. 이러한 조성으로 각 성분을 혼합기에 차례로 투입하여 충분히 교반하여 무기계 결합제 반제품을 제조할 수 있다.When the maintenance preventive composition for pavement of the present invention is used, the inorganic binder to be mixed with the liquid binder is usually 30 to 70% by weight of portland cement, 10 to 30% by weight of silicon dioxide, 0.1 to 15% by weight of alumina, 0.1 to 15% by weight of calcium sulfoaluminate, 10 to 30% by weight of gypsum, 0.1 to 10% by weight of blast furnace slag and 0.01 to 10% by weight of sulfur powder of nanoparticles. With these compositions, each component is put into a mixer in turn and sufficiently stirred to produce an inorganic binder-finished product.

상기 무기계 결합제는 보통 포틀랜트 시멘트 30~70 중량%와 이산화규소 10~30 중량%를 포함하는 것이 바람직한데, 상기 이산화규소는 스프레이 시멘트의 초기강도와 장기강도를 개선하는 효과가 있다.The inorganic binder preferably contains 30 to 70% by weight of portland cement and 10 to 30% by weight of silicon dioxide. The silicon dioxide has an effect of improving initial strength and long-term strength of spray cement.

알루미나 및 칼슘설포알루미네이트의 합산 함량이 0.2~30 중량%이 되도록 포함되는 것이 바람직한데, 합산 함량이 30 중량% 이상이면 초기 경화가 너무 빨라서 작업이 곤란한 문제점이 존재하고, 합산 함량이 0.2 중량% 미만일 경우에는 초속경 결합제의 속경화성 및 초기 강도의 효과가 감소하는 문제점이 발생하게 된다.Alumina and calcium sulfoaluminate is 0.2 to 30% by weight. When the total content is more than 30% by weight, the initial curing is too rapid and the operation is difficult, and when the total content is less than 0.2% by weight, , There arises a problem that the effect of fast curability and initial strength of the quick-setting binder is reduced.

석고는 2개 이상의 무수석고를 사용하는 것이 바람직한데, 합산 함량은 10~30 중량%의 범위가 바람직한데, 석고의 함량이 30 중량% 이상이면 작업성이 떨어지고, 10 중량% 이하인 경우에는 초기 강도가 낮아지는 문제점이 발생한다. It is preferable to use two or more anhydrous gypsum. The total content of the gypsum is preferably in the range of 10 to 30 wt%. When the content of gypsum is more than 30 wt%, the workability is poor. When the gypsum content is less than 10 wt% Is lowered.

일반적으로 고로슬래그는 수화열을 낮추고 내구성을 높여주며, 투수성이 낮고 내화학성이 우수하다. Generally, blast furnace slag lowers hydration heat, improves durability, low permeability and excellent chemical resistance.

또한, 무기계 결합제에 포함되는 시멘트는 반드시 보통 포틀랜트 시멘트로 한정되는 것은 아니며, 사용 목적에 따라서 초속경 시멘트 또는 조강 시멘트를 사용하는 것도 가능하다. In addition, the cement contained in the inorganic binder is not always limited to ordinary portland cement, and it is also possible to use cement with fast speed or crude steel cement according to the purpose of use.

The sulfur powder used as the inorganic binder preferably contains 0.01 to 10% by weight of a sulfur powder having a nanoparticle size that is surface-modified by hydrophilicity. The sulfur powder is preferably used for reinforcing the durability and strength of the cement concrete, It also plays a role of improving salt resistance and the like.

[ 실험예 2] 아크릴 에멀젼 수지와 착색 안료 페이스트는 상기 실험예 1과 동일하게 제조하였으나, 무기계 결합제를 별도로 혼합하는 2성분계 혼합 조성이 아닌, 액상 바인더 단독의 1액형 조성물을 제조하였다. [ Experimental Example 2] The acrylic emulsion resin and the colored pigment paste were prepared in the same manner as in Experimental Example 1, except that the liquid binder alone was used instead of the two-component system in which the inorganic binder was separately mixed.

상기 표 3과 같이 각 조성 성분의 유무에 따른 유황의 친수화 여부를 도 1 또는 도 2와 같이 물과 혼합한 뒤 상분리 여부를 관찰하여 확인하였다. 플라이 애쉬를 기본 성분으로 고정한 후 각각 실리카 흄, 벤토나이트, 분산제, 계면활성제의 유무에 따른 친수화 정도를 확인한 결과, 실리카 흄 또는 벤토나이트 중 어느 한 성분이 나머지 분산제와 계면활성제와 같이 혼합될 경우에는 유황이 초미분화와 동시에 친수화됨을 알 수 있었다. 하지만, 실리카 흄과 벤토나이트가 모두 결여되거나, 계면활성제 또는 분산제 중 어느 하나라도 빠질 경우에는 유황의 친수화가 이루어지지 않음을 알 수 있었다.As shown in Table 3, the hydrophilicity of the sulfur depending on the presence or absence of each component was confirmed by observing whether or not phase separation occurred after mixing with water as shown in FIG. 1 or FIG. After fixing the fly ash as a basic component, the degree of hydrophilization depending on the presence or absence of silica fume, bentonite, dispersant and surfactant was checked. As a result, when any one component of silica fume or bentonite was mixed with the other dispersant and surfactant, It was found that the micropowders were hydrophilized at the same time. However, when either silica fume or bentonite is absent or surfactant or dispersant is missing, the hydrophilic nature of the sulfur is not achieved.
