Description
본 발명은 도막조성물을 이용한 교면방수공법에 관한 것으로서, 더욱 상세하게는, 아스팔트를 주재로 하는 교면용 도막재에 클로로술폰화 폴리에틸렌고무의 개질제를 포함함에 따라 복원력과 충격 흡수가 가능하며 내열성, 내후성을 향상시키도록 하는 도막조성물을 이용한 교면방수공법에 관한 것이다.The present invention relates to a bridge surface waterproofing method using a coating film composition, and more particularly, by including a modifier of chlorosulfonated polyethylene rubber in a bridge surface coating material mainly composed of asphalt, restoring force and shock absorption are possible, and heat resistance and weather resistance It relates to a bridge waterproofing method using a coating film composition to improve the
일반적으로, 교면방수재는 침투수로부터 바닥판을 보호하는 기능을 하며, 방수성 및 접착성 확보, 구조적 동일체 형성, 내구성 확보 등의 역할을 한다. 물이 침투되면 콘크리트 바닥판에서는 피로 파손이 촉진되며, 철근 및 강재에 부식을 일으켜 교량의 내구성을 저하시키므로 방수층은 물의 침투를 방지하여 포장과 바닥판의 내구성을 향상시키기 위한 층으로 중요한 역할을 한다.In general, the bridge surface waterproofing material functions to protect the floor plate from infiltration water, and serves to secure waterproofness and adhesiveness, form a structural body, and secure durability. When water penetrates, fatigue damage is promoted in the concrete deck, and corrosion of reinforcing bars and steel reduces the durability of the bridge. .
또한, 교면방수재는 교통차량에 의한 반복하중, 진동, 충격, 전단 등의 역학적 작용 및 온도변화로 인한 콘크리트 바닥판의 수축 팽창으로 인하여 최근 콘크리트 바닥판의 파손 사례가 빈번하게 발생하고, 이에 대한 보수, 보강으로 사회적 비용이 과다하게 투입되고 있다.In addition, in the case of bridge waterproofing materials, recent cases of breakage of concrete floor boards frequently occur due to the contraction and expansion of concrete floor boards due to temperature changes and mechanical actions such as repeated loads, vibrations, shocks, and shearing caused by traffic vehicles. , the social cost is excessively invested in reinforcement.
이에, 상기 교면방수재는 적용초기에 중요성이 인식되지 않아 기준이 정립되지 않았으나, 최근에는 다양한 방수재료와 공법들이 개발되면서 교량 바닥판 보호 및 아스팔트 층과의 역학적 관계에도 영향을 미친다는 연구결과에 따라 그 중요도가 높아지고 있다. 즉, 교면방수재는 방수성과 함께 콘크리트 바닥면층과 아스팔트 포장층과의 완전한 접착력이 중요시되며 교통차량에 의한 지속적인 하중, 진동, 충격 등을 견딜 수 있는 성능을 발휘할 수 있어야 한다.Therefore, the importance of the bridge waterproofing material was not recognized in the early stage of application, so the standard was not established. Its importance is increasing. In other words, the perfect adhesion between the concrete floor layer and the asphalt pavement layer is important as well as the waterproofness of the bridge surface waterproofing material, and it must be able to exhibit the ability to withstand continuous loads, vibrations, and shocks caused by traffic vehicles.
또한, 상기 교면방수재는 적용공법에 따라 시트공법 및 도막공법으로 구분할 수 있고, 상기 시트공법은 우수한 방수효과와 포장층과의 접착력이 좋다는 장점이 있으나, 교면 표면이 균일하지 않거나 동절기 시공시 콘크리트 수축에 의한 접착불량으로 하자발생 가능성이 높다는 문제점이 있다.In addition, the bridge surface waterproofing material can be divided into a sheet method and a coating method according to the application method, and the sheet method has the advantage of excellent waterproofing effect and good adhesion to the pavement layer, but the bridge surface surface is not uniform or the concrete shrinkage during winter construction There is a problem in that the possibility of defects is high due to poor adhesion.
상기 도막공법은 보수공사시에 쉽게 적용할 수 있다는 장점이 있으며, 교량 바탕층과의 접착력이 우수하기 때문에 방수효과가 뛰어나다. 그러나, 교통으로 인한 진동에 영향을 받을 수 있고 접착력이 떨어지는 도막재 시공으로 인한 아스콘 탈리현상이 발생하는 문제점이 있다. The coating method has the advantage that it can be easily applied during repair work, and has an excellent waterproofing effect because of its excellent adhesion to the bridge base layer. However, there is a problem in that it may be affected by vibrations caused by traffic, and ascon detachment occurs due to the construction of a coating material with poor adhesion.
그러므로, 교면용 도막공법 분야에서는 내열성과 내후성을 향상시켜 교면의 바닥층과 아스콘 포장층의 접착력을 향상시킬 수 있는 고탄성 도막재의 개발에 집중하고 있는 실정이다.Therefore, in the field of coating method for bridge surfaces, the development of high-elasticity coating materials that can improve the adhesion between the bottom layer of bridge surfaces and asphalt concrete pavement layers by improving heat resistance and weather resistance is concentrating on the development.
상기와 같은 문제점을 해결하기 위해 제안하는 것으로서, 본 발명의 목적은, 아스팔트를 주재로 하는 교면용 도막재에 클로로술폰화 폴리에틸렌고무의 개질제를 포함함에 따라 복원력과 충격 흡수가 가능하며 내열성, 내후성을 향상시키도록 하는 도막조성물을 이용한 교면방수공법을 제공하는 데 있다.As proposed in order to solve the above problems, the object of the present invention is to include a modifier of chlorosulfonated polyethylene rubber in the asphalt-based paint film for bridge surfaces, so that restoring force and shock absorption are possible, and heat resistance and weather resistance are improved. An object of the present invention is to provide a bridge waterproofing method using a coating film composition to be improved.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 교면방수공법은 도 1에 도시된 바와 같이, 바탕면에 순차적으로 도막층(10)과, 펠트층(20), 및 아스콘 포장층(30)으로 시공되어 이루어진다.As shown in FIG. 1, the bridge waterproofing method of the present invention is sequentially constructed with a
상기 도막층(10)은 교면의 바탕면에 일정두께 도포하여 1차 방수성능을 발휘하도록 기능을 수행한다.The
상기 도막층(10)은 51 ~ 61중량부의 아스팔트와, 15 ~ 30중량부의 개질제와, 15 ~ 20중량부의 충전제와, 1 ~ 5중량부의 수분흡수제, 및 0.1 ~ 2중량부의 반응속도조절제를 포함하여 조성된다.The
아스팔트는 교면용 도막층(10)의 주재로서, 90 ~ 95중량부의 스트레이트(straight) 아스팔트, 및 5 ~ 10중량부의 브로운(blown) 아스팔트로 조성된다. 물론, 이에 한정하는 것은 아니며, 상기 아스팔트는 스트레이트 아스팔트일 수 있다.Asphalt is the main material of the
상기 브로운 아스팔트는 침입도가 10 ~ 40, 연화점이 80 ~ 100℃인 것이 바람직하다.It is preferable that the blown asphalt has a penetration of 10 to 40 and a softening point of 80 to 100°C.
또한, 상기 아스팔트는 산화 아스팔트를 사용함이 바람직하다.In addition, the asphalt is preferably oxidized asphalt.
산화 아스팔트는 하절기 소성변형, 동절기 저온균열, 충격에 의한 피로균열 등을 방지할 수 있다. 또한, 다른 아스팔트와 대비하여 가격이 저렴하고, 점착성, 내수성, 광택성, 전기절연성 및 방청성이 우수하다.Oxidized asphalt can prevent plastic deformation in summer, low-temperature cracking in winter, and fatigue cracking due to impact. In addition, compared to other asphalt, the price is low, and the adhesiveness, water resistance, glossiness, electrical insulation and rust prevention are excellent.
이 경우, 상기 아스팔트는 51중량부 미만이면 주제로서 원활한 도막층을 형성할 수 없고, 61중량부 초과하면 다른 조성물의 조성관계에 영향을 미침에 따라 KS F 4932(콘크리트 교면용 도막 방수재)에서 요구되는 품질성능 기준을 만족시킬 수 없다는 문제점이 있다.In this case, if the asphalt is less than 51 parts by weight, it cannot form a smooth coating layer as a main ingredient, and if it exceeds 61 parts by weight, it affects the compositional relationship of other compositions. There is a problem in that it cannot satisfy the standard of quality performance.
상기 개질제는 아스팔트를 개질시켜 KS F 4932(콘크리트 교면용 도막 방수재)에서 요구되는 품질성능 기준을 만족시킬 수 있도록 한다. 이 경우, 15중량부 미만이면 요구되는 개질성능을 발휘할 수 없고, 30중량부 초과하면 다른 조성물에 영향을 미치게 된다.The modifier modifies the asphalt to satisfy the quality performance standards required in KS F 4932 (coating waterproofing material for concrete bridge surfaces). In this case, when it is less than 15 parts by weight, the required modifying performance cannot be exhibited, and when it exceeds 30 parts by weight, other compositions are affected.
또한, 상기 개질제는 50 ~ 60중량부의 가소제와, 5 ~ 20중량부의 프로세스 오일과, 15 ~ 20중량부의 클로로술폰화 폴리에틸렌고무(CSM)와, 5 ~ 10중량부의 폴리올레핀계 수지와, 1 ~ 5중량부의 클로로폴리올레핀계 수지, 및 1 ~ 5중량부의 석유수지를 포함하여 조성된다.In addition, the modifier is 50 to 60 parts by weight of a plasticizer, 5 to 20 parts by weight of process oil, 15 to 20 parts by weight of chlorosulfonated polyethylene rubber (CSM), 5 to 10 parts by weight of a polyolefin-based resin, and 1 to 5 It is composed of a chloropolyolefin-based resin in parts by weight, and 1 to 5 parts by weight of a petroleum resin.
상기 가소제는 성형 및 가공성을 향상시키도록 점도를 조절하는 기능을 수행한다. 이 경우, 50중량부 미만이면 점도조절 성능이 저하되고, 60중량부 초과하면 점도조절이 과도하여 성형성을 저하시키게 된다.The plasticizer performs a function of adjusting the viscosity to improve molding and processability. In this case, when it is less than 50 parts by weight, the viscosity control performance is deteriorated, and when it exceeds 60 parts by weight, the viscosity control is excessive and the moldability is deteriorated.
또한, 상기 가소제는 아디페이트(adipate)계 이다. 예컨대, 상기 가소제는 무독성 및 내한성을 가지는 디옥틸 아디페이트(Di 2-ethyl-hexyl-adipate, DOA) 또는 BXA임이 바람직하다.In addition, the plasticizer is adipate-based. For example, the plasticizer is preferably dioctyl adipate (Di 2-ethyl-hexyl-adipate, DOA) or BXA having non-toxicity and cold resistance.
상기 프로세스 오일은 경도를 낮춰 점도를 조절시키는 기능을 수행한다. 5중량부 미만이면 점도조절 성능이 저하되고, 20중량부 초과하면 점도조절 성능에 영향을 미쳐 성형성을 저하시키게 된다.The process oil performs a function of adjusting the viscosity by lowering the hardness. When it is less than 5 parts by weight, the viscosity control performance is lowered, and when it exceeds 20 parts by weight, the viscosity control performance is affected and the moldability is reduced.
상기 클로로술폰화 폴리에틸렌고무(CSM)는 폴리에틸렌을 염소와 이산화황가스를 적정한 비율로 혼합하여 반응시켜 얻어지는 것으로서, 예컨대, SEBS(styrene-ethylene-butadiene-styrene) 또는 SBS(styrene butadiene styrene)이며, 콘크리트 바닥층과 아스콘 포장층 사이의 접착력을 증대시켜 상기 아스콘 포장층의 탈리현상을 방지 또는 지연시킬 수 있도록 한다. 이 경우, 5중량부 미만이면 접착력 향상 기능을 발휘하지 못하고, 10중량부 초과하면 접착력이 향상되나 재료추가에 따른 제조단가의 상승으로 경제적이지 못하다는 문제점이 있다.The chlorosulfonated polyethylene rubber (CSM) is obtained by reacting polyethylene by mixing chlorine and sulfur dioxide gas in an appropriate ratio, for example, styrene-ethylene-butadiene-styrene (SEBS) or styrene butadiene styrene (SBS), and a concrete floor layer By increasing the adhesion between the asphalt concrete and the pavement layer, it is possible to prevent or delay the detachment of the asphalt concrete pavement layer. In this case, if it is less than 5 parts by weight, the adhesive strength improving function cannot be exhibited, and if it exceeds 10 parts by weight, the adhesive strength is improved, but there is a problem in that it is not economical due to an increase in the manufacturing cost according to the addition of material.
상기 폴리올레핀계 수지는 화학적, 기계적 및 전기적 특성이 우수함에 따라 교면용 도막층에 대한 보강성을 향상시키도록 하는 기능을 수행한다. 이 경우, 5중량부 미만이면 보강성 향상기능이 미비하고, 10중량부 초과하면 보강성능의 향상이 미비하나 재료추가에 따른 제조단가의 상승으로 경제적이지 못하다는 문제점이 있다.As the polyolefin-based resin has excellent chemical, mechanical and electrical properties, it performs a function of improving the reinforcing properties of the coating layer for bridge surfaces. In this case, if it is less than 5 parts by weight, the reinforcing improvement function is insufficient, and if it exceeds 10 parts by weight, the improvement of the reinforcing performance is insufficient, but there is a problem that it is not economical due to an increase in the manufacturing cost due to the addition of materials.
상기 클로로폴리올레핀계 수지는 교면용 도막층에 대한 내열성을 향상시키도록 하는 기능을 수행한다. 이 경우, 1중량부 미만이면 내열성의 향상이 미비하고, 5중량부 초과하면 내열성의 향상이 미비하나 재료추가에 따른 제조단가의 상승으로 경제적이지 못하다는 문제점이 있다.The chloropolyolefin-based resin functions to improve the heat resistance of the coating layer for bridge surfaces. In this case, when it is less than 1 part by weight, the improvement in heat resistance is insufficient, and when it exceeds 5 parts by weight, the improvement in heat resistance is insufficient, but there is a problem in that it is not economical due to an increase in the manufacturing cost according to the addition of a material.
상기 석유수지는 점착성을 부여 콘크리트 바닥층과 아스콘 포장층 사이에 접착력을 강화시키도록 하는 기능을 수행한다. 이 경우, 1중량부 미만이면 점착부여 기능이 미비하고, 5중량부 초과하면 점착부여의 향상이 미비하나 재료추가에 따른 제조단가의 상승으로 경제적이지 못하다는 문제점이 있다.The petroleum resin serves to strengthen the adhesion between the concrete floor layer and the asphalt concrete pavement layer by imparting adhesiveness. In this case, when it is less than 1 part by weight, the tackifying function is insufficient, and when it exceeds 5 parts by weight, the improvement of tackifying is insufficient, but there is a problem in that it is not economical due to an increase in the manufacturing cost due to the addition of a material.
또한, 상기 석유수지는 디시클로펜타디엔(Dicyclopentadiene)임이 바람직하다.In addition, the petroleum resin is preferably dicyclopentadiene (Dicyclopentadiene).
상기 충전제는 원가절감과 함께 물리적 강도를 향상시키도록 하는 기능을 수행한다. 상기 충전제는 무기질 필러로서, 예컨대, 탄산칼슘과, 탈크, 실리카, 마이카, 클레이, 침상형 무기질 분말(월러스토나이트, wallastonite) 또는 규조토 중 어느 하나 또는 2종 이상을 혼합하여 사용한다. 이 경우, 상기 탄산칼슘과 탈크 및 규조토를 1 : 0.5 : 0.5 중량비율로 혼합하여 사용한다. 이는, 교면용 도막층에 대한 충격 흡수를 통한 내구성이 향상되도록 한다. 이 경우, 15중량부 미만이면 강도 향상성능이 미비하고, 20중량부 초과하면 점도가 높아지고 점착력이 약화되면 교면용 도막층의 탄성이 줄어들게 된다.The filler performs a function of improving physical strength while reducing cost. The filler is an inorganic filler, for example, calcium carbonate, talc, silica, mica, clay, needle-shaped inorganic powder (wallastonite, wallastonite), or diatomaceous earth, any one or two or more types are mixed and used. In this case, the calcium carbonate, talc and diatomaceous earth are mixed and used in a weight ratio of 1:0.5:0.5. This allows to improve durability through shock absorption for the coating layer for bridge surfaces. In this case, when it is less than 15 parts by weight, the strength improvement performance is insufficient, and when it exceeds 20 parts by weight, the viscosity increases and the adhesive force is weakened, the elasticity of the bridge surface coating layer is reduced.
상기 수분흡수제는 도막층을 조성하는 과정 또는 외부로부터 침투하는 수분을 제거하도록 하는 기능을 수행한다. 상기 수분흡수제는 벤토나이트, 석회, 시멘트, 실리카 겔 또는 합성수지 중 선택된 1종 또는 이들 2종 이상을 혼합한 것이다. 이 경우, 1중량부 미만이면 원활한 수분 흡수성능이 발휘되지 않고, 5중량부 초과하면 도막층 조직의 치밀성을 해치며 가격을 상승시키게 된다.The moisture absorbent performs a function of removing moisture penetrating from the outside or in the process of forming a coating layer. The moisture absorbent is one selected from bentonite, lime, cement, silica gel, and synthetic resin, or a mixture of two or more thereof. In this case, when it is less than 1 part by weight, smooth water absorption performance is not exhibited, and when it exceeds 5 parts by weight, the denseness of the structure of the coating film is impaired and the price is increased.
상기 반응속도조절제는 도막층의 경화속도를 조절하는 것으로서, 0.1 중량부 미만이면 원활한 반응속도 조절성능을 발휘하지 못하고, 2중량부 초과하면 조성물들의 교반과정 중 경화가 이루어져 성형성과 제조성을 저하시키게 된다.The reaction rate controlling agent is to control the curing rate of the coating layer, and when it is less than 0.1 parts by weight, it does not exhibit a smooth reaction rate control performance, and when it exceeds 2 parts by weight, hardening occurs during the stirring process of the compositions, thereby reducing moldability and manufacturability. .
또한, 상기 도막층과 바탕면 사이에는 상기 도막층에 대한 부착성을 향상시키도록 상기 바닥면에 아스팔트 프라이머층을 선(先) 시공한다. 이 경우, 상기 아스팔트 프라이머층은 아스팔트를 주제로 하여 조성되는 도막층과의 친화력에 의해 상기 도막층과 바탕면 사이의 부착력을 향상시킬 수 있도록 한다. 경우에 따라서 상기 아스팔트 프라이머층은 생략할 수 있다.In addition, an asphalt primer layer is pre-constructed on the bottom surface between the coating film layer and the base surface to improve adhesion to the coating film layer. In this case, the asphalt primer layer can improve the adhesion between the coating layer and the base surface by affinity with the coating layer composed of asphalt as the main material. In some cases, the asphalt primer layer may be omitted.
