Description
본 발명은 고무아스팔트 도막방수재에 관한 것으로서 구체적으로는 기존에 사용하고 있는 수계 고무 아스팔트 도막방수재에 내한성 향상 및 난연성이 우수한 수계 고무 아스팔트 도막 방수재 및 이의 시공방법에 관한 것으로 보다 상세하게는 내한성소재와 난연제를 이용한 수계 고무 아스팔트 도막 방수재 에 관한 것이다.The present invention relates to a waterproof rubber asphalt coating material, and more particularly, to a waterproof rubber asphalt coating waterproofing material having excellent cold resistance and flame retardancy and a method of applying the waterproof rubber asphalt coating waterproofing material, Based asphalt coating material using water.
일반적으로 건축물 등의 구조물에서 지붕, 바닥, 지하 주차장 등 수분과 접하는 부위에는 수분이 내부로 스며드는 것을 방지하기 위하여 구조물의 표면에 불투수성의 방수층을 형성하는 방수 공사가 행해지고 있다.Generally, waterproofing work is performed to form impermeable waterproof layer on the surface of a structure in order to prevent moisture from penetrating into the interior of a roof, a floor, an underground parking lot, and the like in a structure such as a building.
이러한 방수 공법으로는 종래부터 다양한 방식이 개발되어 시공되고 있으나 현재 가장 일반적으로 사용되고 있는 방법은 도막 방수 공법과 시트 방수 공법이라고 할 수 있다.In this waterproofing method, various methods have been conventionally developed and constructed, but the most commonly used methods are the coating waterproofing method and the sheet waterproofing method.
일반적으로 도막방수재와 시트 방수재는 고분자 물질을 함유 하고 있다.Generally, the coating and waterproofing materials contain polymeric materials.
특히 아스팔트를 소재로 하여 방수재를 제조할 경우는 기계적 강도나 탄성, 열변형온도, 내한성, 내후성을 향상 시키기 위하여 고무를 혼합하여 아스팔트의 성능을 개질한다,이러한 이유에서 수계 고무 아스팔트 도막방수재 역시 음이온 유화 아스팔트를 주성분으로 하고 이를 개질하기 위하여 수용성 합성고무를 혼합하여 사용한다.In particular, when a waterproofing material is manufactured using asphalt as a base material, the performance of the asphalt is modified by mixing rubber to improve the mechanical strength, elasticity, heat distortion temperature, cold resistance and weather resistance. For this reason, the aqueous rubber asphalt coating waterproofing material is also anionic Asphalt is used as a main component and a water-soluble synthetic rubber is mixed and used to modify it.
수계 고무 아스팔트 도막방수재는 유화 아스팔트에 유화 고무 및 고분자 수지, 유화 첨가제를 혼합하여 각종 건축물의 옥상, 외벽, 터널 및 지하실 등의 표면에는 방수 또는 방식 도막을 형성하는 것이 일반적이다.Water-based rubber asphalt coating materials are generally mixed with emulsified rubber, polymer resin and emulsifying additive to emulsified asphalt to form a waterproof or anticorrosive coating on surfaces of rooftops, outer walls, tunnels and basements of various buildings.
수계 고무 아스팔트 도막방수재는 경제적, 기술적인 측면을 고려 할 때 고무의 함량을 높이는데 한계가 있으며 극한 지방에서의 경우에 저온에서 구조물의 균열이 발생시 구조물 거동에 대한 대응성이 부족하다Water based rubber asphalt coating waterproofing materials have limitations in increasing the rubber content when considering economical and technical aspects and lack of responsiveness to structural behavior when cracks occur at low temperatures in extreme fat
또한 유기 고분자 수지는 열에 취약하여 연소원이 있을 경우 열에 의해 고분자 사슬이 분해되어 가연성 가스가 다량 발생한다. 이때 생성된 분해물이 산소와 반응하여 연소되며 발생한 열이 다시 고분자를 분해하는 연쇄 반응으로 지속적인 연소가 일어나고 다량의 연기와 함께 높은 연소열이 발생한다.In addition, the organic polymer resin is vulnerable to heat, and when there is a combustion source, the polymer chain is decomposed by heat, and a large amount of combustible gas is generated. At this time, the generated decomposition product reacts with oxygen and burns, and the generated heat is decomposed again, resulting in continuous combustion, and a large amount of smoke and high combustion heat are generated.
이러한 문제점으로는 시공 후의 효과의 차이점, 재시공 시의 인건비 문제, 시공 편의성, 자외선에 의한 노화 및 변질 문제, 흡수성 문제, 피착제와의 접착성 문제 , 화재발생시 위험성등을 들 수 있으며 최근에 와서는 시공상의 편의성 및 경제성이 건물 보수업계, 방수업계에서 문제로 부각되고 있다.These problems include differences in effect after construction, labor costs in rework, ease of installation, aging and deterioration due to ultraviolet rays, water absorption problems, adhesion problems with adherends, and fire hazards. Recently, The convenience of construction and economical efficiency are becoming a problem in the building maintenance industry and the waterproofing industry.
즉, 종래의 수계 고무화 아스팔트 도막방수재는 저온상태가 지속되는 환경에서 외부의 접촉이나 충격에 의한 방수층 손상을 초래하여 바탕면에 균열이 발생되거나, 발생 가능성이 큰 건물의 경우 바탕 콘크리트면에 방수층의 동반 파괴현상이 발생할 수 있는 문제점이 있다.That is, the conventional water-based rubberized asphalt coating waterproofing material may cause cracks on the base surface due to damage to the waterproof layer due to external contact or impact in an environment in which the low temperature state is maintained, There is a problem in that the co-destruction phenomenon of the coils may occur.
또한 화재 발생 시 고온으로 인한 콘크리트 구조물의 폭렬 및 내구성 저하와 더불어 인적, 물적 피해가 증가한다.In addition, fire and explosion of concrete structure due to high temperature and durability decrease, human and material damage increase.
이는 건축 구조물의 장기 내구성 감소로 유지보수 비용의 증가를 초래하게 되는 단점이 발생한다.This results in a disadvantage that maintenance cost is increased due to a decrease in long term durability of the building structure.

상기 유화 아스팔트라 함은 석유 아스팔트의 하나로서, 스트레이트 아스팔트의 1~5㎛의 미세한 입자로 만들어 물에 분산시킨 것을 의미한다. 상기 유화아스팔트는 양전하를 갖는 양이온계(Cation) 유화 아스팔트, 음전하를 갖는 음이온계(Anion) 유화 아스팔트 및 양전하/음전하를 모두 갖지 않는 비이온계(Nonion) 유화 아스팔트로 구분할 수 있다.The above-mentioned emulsified asphalt refers to one of petroleum asphalt which is made into fine particles of 1 to 5 탆 of straight asphalt and dispersed in water. The emulsified asphalt may be classified into a cationic emulsified asphalt having a positive charge, an anionic emulsified asphalt having a negative charge and a nonionic emulsified asphalt having neither a positive charge nor a negative charge.
본 발명에서 이용된 유화 아스팔트는 pH 8 이상이면서 음이온인 유화 아스팔트인 것이 바람직하다. pH가 8이상이 되면 물과 아스팔트의 상용성이 우수하며 분산상태가 양이온이나 비이온일때보다 고르게 미립으로 분산되어 저장과정에서 침전물이 발생하지 않고 저장안정성이 우수하다.The emulsified asphalt used in the present invention is preferably an emulsified asphalt having a pH of 8 or more and an anion. When the pH is above 8, the compatibility of water and asphalt is good. The dispersed state is more uniformly dispersed than the cation or non-ionic state, and the storage stability is excellent without deposits during storage.
본 발명은 pH 8이상의 음이온 수용성 합성고무를 이용하는 데, 20~50중량%인 것이 바람직하다. 상기 합성고무는 탄성 및 내한성능을 향상시킬 수 있는 데, 도막 방수재에 열가소성 수지를 이용함으로써 발생하는 내한성능이 떨어지는 문제를 보완하기 위해 첨가된다. 또한, 상기 합성고무는 복원력을 좋게 하고 내화학성 및 내오존성을 좋게 할 수 있는 장점이 있다.The present invention employs an anionic water-soluble synthetic rubber having a pH of 8 or more, preferably 20 to 50% by weight.

또한, 상기 합성고무는 pH 8이상이면서 음이온인 수용성 합성고무를 이용하는 것이 바람직한데, 음이온의 합성고무를 이용하는 이유는 양이온이나 비이온일 상분리에 의한 저장안정성이 저하되는 문제점이 발생한다. 따라서, 음이온의 합성고무를 이용하는 것이 바람직하다. 또한, pH 8이상의 합성고무를 이용함으로써 pH 혼합물의 저장안정성을 유지하도록 하게 한다.In addition, it is preferable to use a water-soluble synthetic rubber which is an anion having a pH of 8 or more. The reason for using the synthetic rubber of an anion is that the storage stability due to cationic or nonionic one-phase separation is deteriorated. Therefore, it is preferable to use an anionic synthetic rubber. Also, by using a synthetic rubber having a pH of 8 or more, the pH stability of the mixture is maintained.
상기 합성고무는 SBR, CR, NBR 및 NR 로 이루어진 군에서 1이상 선택되는 것이 바람직하다.The synthetic rubber is preferably at least one selected from the group consisting of SBR, CR, NBR and NR.

The surfactant is mixed with 3 to 10 wt% .
상기 계면활성제가 3중량% 미만이면 각 원료간 엉김현상이 발생 할 수 있으며 10중량% 초과하면 도막방수재가 겔화 될 수 있다.If the amount of the surfactant is less than 3% by weight, entanglement may occur between the respective raw materials. If the surfactant is more than 10% by weight, the coating film waterproofing material may gel.
한편, 본 발명의 내한성소재는 도막방수재의 극저온에서의 구조물과의 동반 파괴를 방지하기 위하여 혼합하는데 40℃ 이하에서도 방수층의 균열을 방지하기 위하여 DOTP(디옥틸테레프탈레이트) 또는 DINP(디이소노닐프탈레이트)를 단독 또는 혼합 사용할 수 있다.Meanwhile, the cold-resistant material of the present invention is mixed to prevent co-destruction with the structure at a cryogenic temperature of the coating film waterproofing material, and DOTP (dioctyl terephthalate) or DINP (diisononyl phthalate ) May be used alone or in combination.
이때 내한성소재는 3~15중량%를 혼합하는데 3중량% 미만이면 40℃에서 균열이 발생하며 15중량% 초과이면 유화가 어려워 상용성이 저하된다.At this time, 3 to 15% by weight of the cold-resistant material is mixed. If the amount is less than 3% by weight, cracking occurs at 40 ° C. If the amount is more than 15% by weight, emulsification is difficult.
또한 본 발명의 난연제는 테트라프로모비스페놀에이(TBPA), 데카브로모옥사이드(DBDPO), 데카브로모에테인(DBDPE) 등 기체상에서 라디칼을 포착함으로써 난연 역활을 하는 브롬계 난연제1~5중량%를 사용한다.Further, the flame retardant of the present invention is used in an amount of 1 to 5% by weight of a bromine-based flame retardant which acts as a flame retardant by capturing radicals in gas such as tetrapropyl bisphenol A (TBPA), decabromo oxide (DBDPO) and decabromoethane do.
이때 난연제가 1중량% 미만이면 난연효과를 기대 할 수 없으며 5중량부 초과이면 침전물이 발생하여 저장안정성이 저하된다.If the content of the flame retardant is less than 1% by weight, a flame retardant effect can not be expected. If the content is more than 5% by weight, precipitates are formed and storage stability is deteriorated.
또한 난연 안정제로 할로겐계 난연제만 단독 사용할 경우 결합에너지에 따라 특정조건이 되면 일시에 할로겐계 화합물이 분해되어 소비될수 있는데 넓은 온도 범위에서 난연환경을 부여하기 위하여 안티몬계 화합물이나 스테아린산 칼슘을 혼합하여 사용한다.In addition, when a halogen-based flame retardant alone is used as a flame retardant, the halogen-based compound may be decomposed and consumed at certain times depending on the binding energy. In order to impart a flame retardant environment in a wide temperature range, antimony compound or calcium stearate do.
이때 1중량% 이하이면 난연효과를 기대 할수 없으며 5중량% 이상이면 도막방수재의 물성 변화를 발생 시켜 저장안정성이 저하 된다.If the content is less than 1 wt%, the flame retardant effect can not be expected. If the content is more than 5 wt%, the physical properties of the coating film waterproofing material are changed, and the storage stability is lowered.
