Description
본 발명은 규소 고무와 스티렌 부타디엔 스티렌 터폴리머를 주성분으로 하는 도막방수제 및 그 제조방법에 관한 것으로서 더욱 상세하게는 규소 고무와 스티렌 부타디엔 스티렌 터폴리머를 주성분으로 함유하고 여기에 폴리비닐아세테이트, 스트레이트아스팔트, 규사 , 탈크, 탄산칼슘, 아연화, 카본블랙, 마그네시아, 산화방지제 및 노화방지제를 첨가하여 이루어짐으서 건축 토목 구조물의 콘크리트 균열에 의한 누수, 철근의 부식 및 노화를 방지하여 경제적이고 효과적인 구조물 관리를 할 수 있도록 하는 도막방수제와 이를 제조하는 방법에 관한 것이다.The present invention relates to a coating film waterproofing agent containing silicon rubber and styrene butadiene styrene terpolymer as a main component, and more particularly, to a polyvinylacetate, straight asphalt, containing silicon rubber and styrene butadiene styrene terpolymer as main components. It is made by adding silica sand, talc, calcium carbonate, zincation, carbon black, magnesia, antioxidant, and anti-aging agent, so that it is possible to manage structure economically and effectively by preventing leakage, corrosion of steel reinforcement and aging due to concrete cracking of civil engineering structures. It relates to a coating film waterproofing agent and a method of manufacturing the same.
콘크리트 구조물에는 정적, 동적 하중에 의한 휨 모멘트나 진동이 발생하여 균열이 일어나며 중성화 및 노화에 의한 박리가 발생된다.In concrete structures, bending moments or vibrations are generated due to static and dynamic loads, and cracks occur, and delamination due to neutralization and aging occurs.
또한 빗물 등은 콘크리트 표면에 틈이나 균열을 발생시키고, 침투하여 철근을 부식시키므로서 콘크리트의 균열을 촉진시키며 콘크리트에 생긴 균열은 구조적인 문제가 되어 건축 토목 구조물의 수명을 단축시키는 원인이 되고 있다. In addition, rainwater causes cracks or cracks on the surface of the concrete, infiltrates the reinforcing steel bars, and promotes cracking of the concrete, and cracks in the concrete become structural problems, which shortens the lifespan of civil engineering structures.
일반적으로 건축 토목 구조물의 보호 시스템으로 사용되는 방수재료에는 그 시공방식에 따라 쉬트식 방수재료, 도막식 방수재료 및 침투식 방수재료가 있다.Generally, the waterproofing material used as a protection system for building civil engineering structures includes sheet type waterproofing material, coating type waterproofing material and penetration type waterproofing material according to the construction method.
이중 침투식 방수재료를 이용하여 시공하는 방법은 과거에 콘크리트 등의 방수시공에 사용하던 방법으로, 주로 실리콘을 강력한 용제로 용해하여 액상의 침투방수제로 사용한 공법이다.The construction method using the double penetration type waterproofing material is a method used in the past for the waterproofing construction of concrete, and is mainly a method of dissolving silicon in a strong solvent and using it as a liquid penetration waterproofing agent.
그러나 침투식 방수재료를 사용한 시공방법은 균열에 대한 저항성이 낮고, 350㎏f/㎠의 고강도 콘크리트에는 침투가 되지 않는 문제점이 있어 최근에는 사용하지 않고 있다. However, the construction method using the penetration type waterproofing material has low resistance to cracking and has not been used in recent years because it does not penetrate into high-strength concrete of 350 kgf / cm 2.
그리고 쉬트식 방수시공은 균일하고 우수한 방수효과를 발휘하기는 하지만, 비용이 많이 들고 시공과정에서 쉬트간의 연결작업이 어려워 표면이 균일하지 못하고, 연결부위 누수로 인하여 방수기능을 상실하는 경우도 있다.In addition, although the sheet-type waterproof construction exhibits a uniform and excellent waterproof effect, the surface is not uniform due to high cost and difficult connection work between sheets in the construction process, and the waterproof function may be lost due to leakage of the connection part.
한편, 도막식 방수시공은 연결부위 없는 연속시공이 가능하고, 효과면에서도 우수 하지만 화학적 노화에 의한 콘크리트의 균열에 대한 저항력이 떨어져 방수층의 손상이 생기고 접착력이 약하여 방수성능이 상실되는 단점을 가지고 있었다.
On the other hand, the coating type waterproof construction is capable of continuous construction without connecting parts and is excellent in terms of effect, but has a disadvantage in that the resistance to cracking of the concrete due to chemical aging decreases, resulting in damage to the waterproof layer and weak adhesion, resulting in loss of waterproof performance. .
본 발명은 비교적 내구성, 내약품성, 내노화성, 내오존성, 내후성 그리고 내열성이 우수한 규소 고무와 열가소성으로 시공시 작업성이 우수한 스티렌 부타디엔 스티렌 터폴리머를 주성분으로 하여 기타 첨가제를 첨가한 물리적 화학적 노화현상이 발생하지 않는 새로운 도막방수제와 그 제조방법을 제공함에 있으며 이와 같은 본 발명의 목적달성을 위한 도막방수제는 규소 고무 100 중량부, 스티렌 부타디엔 스티렌터폴리머 70 중량부, 폴리비닐아세테이트수지 30∼80 중량부, 스트레이트 아스팔트 50∼70 중량부, 자일렌 100∼280 중량부, 규사 60∼80 중량부, 탄산칼슘 10∼30 중량부, 탈크 60∼90 중량부, 카본블랙 1∼2 중량부, 마그네시아 1∼3 중량부, 아연화 1∼3 중량부, 노화방지제 6∼8 중량부 및 산화방지제 6∼7 중량부로 이루어진 도막방수제이며 이와 같은 도막방수제의 제조방법은 규소 고무 100 중량부와 스티렌 부타디엔 스티렌 터폴리머 70 중량부, 폴리비닐아세테이트수지 30∼80 중량부, 스트레이트 아스팔트 50∼70 중량부에 자일렌 100∼280 중량부, 규사 60∼80 중량부, 탄산칼슘 10∼30 중량부, 탈크 60∼80 중량부를 첨가하여 65∼75℃에서 5∼8시간 동안 교반하여 규소 고무와 폴리비닐아세테이트수지 및 스티렌 부타디엔 스티렌 브렌딩 용액을 제조하는 단계, 상기 브렌딩 용액에 카본블랙 1∼2 중량부, 마그네시아 1∼3 중량부, 아연화 1∼3 중량부, 노화방지제 6∼8 중량부 및 산화방지제 6∼7 중량부를 혼합하여 65∼75℃에서 1∼2시간 동안 교반 반응시켜서 되는 제조방법과 본 방법에 의한 도막방수제를 제공함에 목적이 있다 하겠다.

It is a coating film waterproofing agent consisting of 3 parts by weight, 1 to 3 parts by weight of zinc, 6 to 8 parts by weight of antioxidant and 6 to 7 parts by weight of antioxidant. The production method of the coating waterproofing agent is 100 parts by weight of silicon rubber, 70 parts by weight of styrene butadiene styrene terpolymer, 30 to 80 parts by weight of polyvinylacetate resin, 50 to 70 parts by weight of straight asphalt, 100 to 280 parts by weight of silica sand 60 to Adding 80 parts by weight, 10 to 30 parts by weight of calcium carbonate and 60 to 80 parts by weight of talc, and stirring at 65 to 75 ° C. for 5 to 8 hours to produce silicon rubber, polyvinylacetate resin and styrene butadiene styrene blending solution. 1 to 2 parts by weight of carbon black, 1 to 3 parts by weight of magnesia, 1 to 3 parts by weight of zinc, 1 to 8 parts by weight of antioxidant, and 6 to 7 parts by weight of antioxidant are mixed at 65 to 75 ° C. It is an object of the present invention to provide a method for producing a coating film waterproofing agent according to the present invention and a method of stirring by stirring for 1-2 hours.
본 발명은 종래 도막방수제의 문제점을 개량 해결한 도막방수제의 제조방법으로 이의 제조방법을 설명하면,The present invention is a manufacturing method of the coating film waterproofing agent which solves the problems of the conventional coating film waterproofing agent,
먼저 자일렌에 규소 고무와 스티렌 부타디엔 스티렌 터폴리머, 스트레이트아스팔트 및 폴리비닐아세테이트수지를 용해한 후 규사, 탄산칼슘 및 탈크를 첨가하 여 점도 1000∼1900cps의 균일한 브렌딩 용액을 제조한다. First, silicon rubber, styrene butadiene styrene terpolymer, straight asphalt and polyvinylacetate resin are dissolved in xylene, and silica sand, calcium carbonate and talc are added to prepare a uniform blending solution having a viscosity of 1000 to 1900 cps.
이때 자일렌의 사용량은 규소 고무 100 중량부와 스티렌 부타디엔 스티렌 터폴리머 70 중량부 폴리비닐아세테이트 수지 30∼80 중량부에 대하여 100∼280 중량부이며 규사 60∼80 중량부, 탄산칼슘 10∼30 중량부, 탈크 60∼90 중량부인 것이 바람직하다. The amount of xylene used is 100 to 280 parts by weight based on 100 parts by weight of silicon rubber and 70 parts by weight of styrene butadiene styrene terpolymer to 30 to 80 parts by weight of polyvinylacetate resin, 60 to 80 parts by weight of silica sand and 10 to 30 parts by weight of calcium carbonate. It is preferable that it is 60-90 weight part of talc.
폴리비닐아세테이트수지는 도막방수제의 레벨성과 접착성 향상을 목적으로 첨가되는 것으로서 밀도 0.72∼0.80(g/cc), 비중 1.2, 연화점 55℃, 대기중 접착강도 180∼220kg/cm2 인 것을 사용하는 것이 바람직하다. Polyvinylacetate resin is added for the purpose of improving the level and adhesiveness of the coating waterproofing agent, and has a density of 0.72 to 0.80 (g / cc), a specific gravity of 1.2, a softening point of 55 ° C, and an adhesive strength of 180 to 220 kg / cm 2 in the air. It is preferable.
탄산칼슘과 탈크는 도막방수제의 난연성 향상을 목적으로 첨가되는 것으로서 탄산칼슘은 입자크기 300 메쉬, 비중 1.7 실리카 함량이 30% 이하인 것이 바람직하고, 탈크는 입자크기 325 메쉬, 비중 0.5 PH 8.9, 실리카 함량이 60% 이상인 것을 사용하는 것이 바람직하다. Calcium carbonate and talc are added to improve the flame retardancy of the coating waterproofing agent, and calcium carbonate preferably has a particle size of 300 mesh and a specific gravity of 1.7 silica content of 30% or less, and talc has a particle size of 325 mesh, specific gravity of 0.5 PH 8.9 and silica content. It is preferable to use this 60% or more.
폴리비닐아세테이트의 사용량이 규소 고무 100 중량부와 스티렌 부타디엔 스티렌 터폴리머 70 중량부에 대하여 30 중량부 이하이거나 80 중량부 이상이면 도막방수제의 레벨성과 접착강도가 떨어져 요철이 심한 콘크리트 바탕에는 사용이 불가능하는 등 시공성이 감소하는 문제가 있다. If the amount of polyvinylacetate is less than 30 parts by weight or more than 80 parts by weight with respect to 100 parts by weight of silicon rubber and 70 parts by weight of styrene butadiene styrene terpolymer, the level and adhesive strength of the coating waterproofing agent may be poor, and thus it may not be used on concrete uneven concrete ground. There is a problem that the workability is reduced.
또한 탄산칼슘과 탈크의 사용량이 최저치 이하이면 도막방수제가 난연성 성질을 갖지 못할 뿐만 아니라 도막 두께의 확보가 어렵고, 최고치 이상이면 인장강도와 신장률 등의 물성이 떨어져 내균열 저항성이 감소하는 문제가 있다. In addition, when the amount of calcium carbonate and talc used is less than the minimum value, the coating waterproofing agent does not have flame retardant properties, and it is difficult to secure the thickness of the coating film. When the amount is more than the maximum value, there is a problem in that crack resistance is decreased due to physical properties such as tensile strength and elongation.
상기와 같은 방법에 브렌딩 용액을 제조한 다음 여기에 카본블랙, 마그네시 아, 아연화, 노화방지제 및 산화방지제를 혼합하고 65∼75℃에서 1∼2시간 교반하여 액상의 도막방수제를 얻는다. After preparing a blending solution in the same manner as described above, carbon black, magnesia, zincation, antioxidants and antioxidants are mixed and stirred at 65 to 75 ° C. for 1 to 2 hours to obtain a liquid coating waterproofing agent.
이때, 카본블랙의 사용량은 규소 고무 100 중량부, 스티렌 부타디엔 스티렌 터폴리머 70 중량부에 대하여 1∼2 중량부, 마그네시아의 사용량은 1∼3 중량부이고, 아연화는 1∼3 중량부, 노화방지제는 6∼8 중량부, 산화방지제는 6∼7중량부가 되도록 첨가한다. At this time, the carbon black is used in an amount of 1 to 2 parts by weight based on 100 parts by weight of silicon rubber, 70 parts by weight of styrene butadiene styrene terpolymer, 1 to 3 parts by weight of magnesia, 1 to 3 parts by weight of zinc, an antioxidant Is added in an amount of 6 to 8 parts by weight and an antioxidant to 6 to 7 parts by weight.
여기서 카본블랙은 보강성 충전제로서, 통상 보강성 충전제로는 카본블랙이나 실리카 등을 사용할 수 있으나 본 발명에서는 스티렌 부타디엔 스티렌 수지와 같은 극성 고무에 효과적인 비표전적 76mg/g의 카본블랙을 사용한다. Herein, carbon black is a reinforcing filler, and as a reinforcing filler, carbon black or silica may be used. However, in the present invention, a non-representative 76 mg / g carbon black is effective for polar rubber such as styrene butadiene styrene resin.
마그네시아와 아연화는 가교 및 가황(Vulcanization)을 촉진시키기 위해 첨가하는 가교제로서, 마그네시아는 저온에서는 안정제로 작용하지만 60℃ 이상에서는 스티렌 부타디엔 스티렌 수지와 급속히 반응하여 가교결합을 형성하기 때문에 그 사용량이 스티렌 부타디엔 스티렌 수지 70 중량부에 대하여 1∼3 중량부인 것이 바람직하다. Magnesia and zincation are crosslinking agents added to promote crosslinking and vulcanization. Magnesia acts as a stabilizer at low temperatures but rapidly reacts with styrene butadiene styrene resins at temperatures above 60 ° C to form crosslinks. It is preferable that it is 1-3 weight part with respect to 70 weight part of styrene resins.
노화방지제로는 통상의 것을 사용할 수 있는 바, 구체적인 예로는 아민계, 비스페놀계, 모노페놀계 및 유황계 노화 방지제가 있다.As the anti-aging agent can be used a conventional one, specific examples include amine-based, bisphenol-based, monophenol-based and sulfur-based antioxidant.
이와 같이 제조한 도막방수제를 건축 토목 구조물 등에 스프레이, 고무 헤라 및 흙손 등을 이용하여 도포하면 우수한 인장강도, 저온유연성, 내충격성, 접착성, 내약품성 및 내마모성을 발휘하여 1회에 2mm 두께로 도포하더라도 도막의 표면 갈라짐 현상과 기포가 발생하지 않으며, 내구성이 우수하여 누수로 인한 구조물의 노 화 현상를 방지할 수 있다. Applying the coating film waterproofing agent prepared in this way to a building civil structure using spray, rubber spatula, trowel, etc., it shows excellent tensile strength, low temperature flexibility, impact resistance, adhesiveness, chemical resistance, and abrasion resistance.
