Description
본 발명은 실란계 졸겔 수지와 아크릴에멸젼을 포함하는 침투식 액체 방수제 및 그 제조 방법에 관한 것으로, 보다 상세하게는 테트라에톡시오르소실란과 메틸트리메톡시실란 등으로 합성한 실란계 졸겔 수지에 아크릴에멀젼를 혼합하여 제조한 것으로 우수한 침투성, 접착성 및 방수 특성을 갖도록 한 실란계 졸겔 수지와 아크릴에멸젼을 포함하는 침투식 액체 방수제 및 그 제조방법에 관한 것이다.
The present invention relates to a permeable liquid waterproofing agent comprising a silane-based sol-gel resin and an acrylic emulsion, and a method for preparing the same. More specifically, the present invention relates to a silane-based sol-gel resin synthesized with tetraethoxy orthosilane, methyltrimethoxysilane, or the like. The present invention relates to a permeable liquid waterproofing agent containing a silane-based sol-gel resin and an acrylic emulsion, which are prepared by mixing an acrylic emulsion and having excellent permeability, adhesiveness, and waterproofing properties, and a method of manufacturing the same.
현재 건축공사에 쓰이고 있는 침투식 액체 방수제로는 많은 것들이 있으나 매우 거칠게 시공되어 있는 국내 콘크리트 구조물에 대해 충분한 침투 및 방수효과를 나타내고 있지 못하고 있는 실정이다. Currently, there are many penetration liquid waterproofing agents used in building construction, but they do not show sufficient penetration and waterproof effect on domestic concrete structures that are very roughly constructed.
예를 들면 각종 지방산을 원료로 한 침투성 방수제 제품은 방수성은 양호하나 콘크리트 모체와의 접착력이 부족하여 시간이 경과 하면 부풀음 현상이 나타난다는 단점이 있다. For example, permeable waterproofing products made of various fatty acids as raw materials have good water resistance, but have a disadvantage of swelling over time due to lack of adhesion to the concrete matrix.
또한 합성수지와 파라핀을 원료로 한 침투성 방수제 제품은 접착력과 방수성은 우수하나 강도가 부족하여 약간의 충격에도 방수층에 균열이 생긴다는 단점이 있다. In addition, the permeable waterproofing product made of synthetic resin and paraffin has excellent adhesive strength and waterproofness, but has a disadvantage in that a crack is generated in the waterproofing layer even with a slight impact due to insufficient strength.
그외 각종 분말형 침투성 방수제는 지하 구조물등 수압의 영향을 받는 부위에 주로 사용되고 있으나 지하 3층 이상, 즉 3kgf/cm2 이상의 압력을 받는 곳에서는 들뜸 현상과 같이 모체인 지하 구조물로부터 방수층이 형성 되기전 생기는 수압의 영향으로 방수층 박리현상의 발생 및 방수층의 취약 부위가 발생하고 있다는 단점이 있다.
In addition, various powder-permeable waterproofing agents are mainly used in areas affected by water pressure, such as underground structures, but before the waterproofing layer is formed from the basement underground structures like the floating phenomenon in places where the pressure is more than 3 underground levels, that is, more than 3kgf / cm 2 . Due to the pressure generated, there are disadvantages in that the waterproofing layer peeling phenomenon occurs and a weak portion of the waterproofing layer is generated.
상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 방수층과 모체와의 접착력 및 침투성 향상되고, 투수비와 흡수비도 낮추어 내구성 및 방수성이 우수한 침투식 액체 도포 방수제 및 그 제조방법을 제공하는 데 있다.

상기 디프로필렌글리콜의 함량이 30.52 중량부 미만이면 실란계 물질을 수성화 하는데 어려움이 있으며, 41.65 중량부 보다 크면 시멘트와의 상용성이 감소한다. When the content of the dipropylene glycol is less than 30.52 parts by weight, it is difficult to aqueousize the silane-based material, and when the content of the dipropylene glycol is greater than 41.65 parts by weight, the compatibility with cement decreases.
상기 에탄올의 함량이 20.42 중량부 미만이면 졸겔 반응이 일어나지 않고, 29.87 중량부 보다 크면 점도가 낮아진다 한다.
If the content of the ethanol is less than 20.42 parts by weight, the sol-gel reaction does not occur, and if it is greater than 29.87 parts by weight, the viscosity is lowered.
상기 증류수의 함량이 45.69 중량부 미만이면 졸겔 수지가 온도에 너무 민감 해지고, 61.01 중량부 보다 크면 유효 성분이 너무 낮아진다.
If the content of the distilled water is less than 45.69 parts by weight, the sol-gel resin is too sensitive to temperature, and if it is greater than 61.01 parts by weight, the active ingredient is too low.
상기 에폭시실란의 함량이 71.36 중량부 미만이면 침투 깊이가 저하되고 92.28 중량부 보다 크면 증류수와 혼화성이 떨어진다.
When the content of the epoxy silane is less than 71.36 parts by weight, the penetration depth is lowered, and when the content of the epoxy silane is greater than 92.28 parts by weight, it is incompatible with distilled water.

If the content of the isopropyl titanate is less than 7.59 parts by weight, the stability of the sol-gel resin is drastically reduced and the viscosity thereof is not available, and if it is greater than 9.43 parts by weight, the reactivity is not reduced due to hydrolysis during the reaction.
상기 테트라에톡시오르소실란의 함량이 3.31 중량부 미만이면 축합 반응이 일어나지 않고, 4.62 중량부 보다 크면 반응이 너무 빨리 일어나 제조 하기가 매우 힘들다.
If the content of the tetraethoxy orthosilane is less than 3.31 parts by weight, the condensation reaction does not occur, if the content is larger than 4.62 parts by weight it is very difficult to prepare the reaction.
상기 메틸트리메톡시실란의 함량이 5.08 중량부 미만이거나 6.77 중량부 보다 크면 방수제의 성능 중 투수비가 증가한다.
When the content of the methyltrimethoxysilane is less than 5.08 parts by weight or greater than 6.77 parts by weight, the permeability ratio of the performance of the waterproofing agent increases.
상기 아크릴에멀젼은 이를 100중량부 기준으로 한 나머지 조성원소와의 혼합비 보다 작으면 접착력이 감소하고, 나머지 조성원소와 혼합비보다 크면 실란계 졸겔 수지와 혼합시 응집물이 발생한다.
When the acrylic emulsion is smaller than the mixing ratio with the remaining composition elements based on 100 parts by weight, the adhesion decreases, and when the acrylic emulsion is larger than the mixing ratio with the remaining components, aggregates are generated when mixed with the silane-based sol-gel resin.
상기에서 테트라에톡시오르소실란은 인화점 45℃, 증기압 2hpa(20℃)인 것을 사용한다.In the above, tetraethoxy orthosilane uses a flash point of 45 ° C. and a vapor pressure of 2 hpa (20 ° C.).
또한 메틸트리메톡시실란은 인화점 9℃, 점화온도 225℃인 것을 사용한다. In addition, methyl trimethoxysilane uses a flash point of 9 ° C and an ignition temperature of 225 ° C.
또한 이소프로필티타네이트는 끓는점 232℃, 녹는점 18℃ ~ 20℃ 인화점 60℃인 것을 사용한다.In addition, the isopropyl titanate uses a boiling point of 232 ° C. and a melting point of 18 ° C. to 20 ° C. and a flash point of 60 ° C.

이하 본 발명의 한 실시예에 따른 제조방법을 설명한다.Hereinafter will be described a manufacturing method according to an embodiment of the present invention.
이하에서 각 중량부 숫자는 아크릴에멀젼 100중량부 기준으로 한 수치이다.In the following, each number by weight is based on 100 parts by weight of the acrylic emulsion.
먼저, 디프로필렌글리콜 30.52 ~ 41.65 중량부, 에탄올 20.42 ~ 29.87 중량부 및 증류수 45.69 ~ 61.01 중량부를 반응기에 주입한 후 온도를 10℃ ~ 15℃로 조절한다. First, 30.52 to 41.65 parts by weight of dipropylene glycol, 20.42 to 29.87 parts by weight of ethanol and 45.69 to 61.01 parts by weight of distilled water are injected into the reactor, and then the temperature is adjusted to 10 ° C to 15 ° C.
이후 10℃ ~ 15℃로 조절된 반응기에 에폭시실란 71.36 ~ 92.28 중량부 및 이소프로필티타네이트 7.59 ~ 9.43 중량부를 첨가 한후 60rpm ~ 100rpm으로 5 ~ 6시간 반응 시킨후 온도를 20℃ ~ 25℃로 승온시키는 단계와;Thereafter, 71.36 to 92.28 parts by weight of epoxysilane and 7.59 to 9.43 parts by weight of isopropyl titanate were added to the reactor adjusted to 10 ° C. to 15 ° C., followed by reaction at 60 rpm to 100 rpm for 5 to 6 hours, and the temperature was raised to 20 ° C. to 25 ° C.

The reason why the temperature is adjusted to 10 ° C. to 15 ° C. after injecting 30.52 to 41.65 parts by weight of dipropylene glycol, 20.42 to 29.87 parts by weight of ethanol and 45.69 to 61.01 parts by weight of distilled water to the reactor under temperature conditions during the preparation of the penetration liquid repellent Beyond this temperature range, it is not a sol-gel resin that can be used as a penetration liquid sealant.
또한 상기 에폭시실란 71.36 ~ 92.28 중량부 및 이소프로필티타네이트 7.59 ~ 9.43 중량부를 첨가 한후 60rpm ~ 100rpm으로 5 ~ 6시간 반응 시킨 후 온도를 20℃ ~ 25℃로 승온하는 이유는 이 온도범위를 벗어나면 침투식 액체 방수제로 사용할 수 있는 졸겔 수지가 되지 않기 때문에 반드시 온도 범위를 지켜야 한다.
In addition, after adding 71.36 to 92.28 parts by weight of the epoxy silane and 7.59 to 9.43 parts by weight of isopropyl titanate, and reacting at 60 rpm to 100 rpm for 5 to 6 hours, the temperature is raised to 20 ° C. to 25 ° C. The temperature range must be maintained because it is not a sol-gel resin that can be used as a penetration liquid sealant.
또한 상기 60rpm ~ 100rpm의 반응속도와 5 ~ 6 시간의 반응시간 그리고 2 ~ 4시간 동안 합성시간을 한정한 이유는 이러한 수치 구간을 벗어나면 침투식 액체 방수제로 사용할 수 있는 졸겔 수지가 잘 되지 않기 때문에 반드시 이러한 조건을 만족해야 한다.
In addition, the reason for limiting the reaction time of 60rpm ~ 100rpm, the reaction time of 5 ~ 6 hours and the synthesis time for 2 to 4 hours is because the sol-gel resin that can be used as a penetration liquid waterproofing agent is not well beyond this numerical range You must meet these conditions.
