고무아스팔트 도막방수제의 제조방법{process for preparing water-proof material}Process for preparing rubber asphalt coating waterproofing agent {process for preparing water-proof material}

본 발명은 고무아스팔트 도막방수제의 제조방법에 관한 것으로서, 더욱 상세하게는 고무계 라텍스 또는 수지를 아스팔트에 혼화하여 도막방수제를 제조하는 데 있어서 아스팔트를 용융한 다음 여기에 고무계 라텍스 또는 아크릴계 폴리머를 서서히 투입하여 균일 혼합시킨 후 유화제를 첨가함으로써 수용성계 라텍스 성분과 아스팔트의 분리를 방지하여 저장안정성을 개선시킬 수 있는 도막방수제의 제조방법에 관한 것이다.The present invention relates to a method for producing a rubber asphalt coating waterproofing agent, and more particularly, in the manufacture of a coating waterproofing agent by mixing rubber-based latex or resin with asphalt, after melting the asphalt, the rubber-based latex or acrylic polymer is gradually added thereto. The present invention relates to a method for preparing a coating waterproofing agent capable of improving storage stability by preventing separation of water-soluble latex components and asphalt by adding an emulsifier after homogeneous mixing.

고무화 아스팔트 도막제는 아스팔트에 고무성분을 첨가함으로써 아스팔트가 가질 수 없는 성질, 즉 우수한 신장율, 내균열성, 내한성, 접합성을 가지도록 하였다.The rubberized asphalt coating agent has a property that asphalt cannot have, ie, excellent elongation, crack resistance, cold resistance, and bondability, by adding a rubber component to the asphalt.

또한, 내열성과 강도 및 경도를 보다 강화시키기 위해 계면활성제나 경화촉진제 등을 첨가하기도 하였으며, 열가소성 엘라스토머 등을 첨가한 것도 있다.In addition, surfactants, curing accelerators, and the like have been added to further enhance heat resistance, strength, and hardness, and thermoplastic elastomers and the like may be added.

상기와 같은 각기 다른 조성의 도막방수제를 실제로 제조할 때, 아스팔트 입자와 고무계 라텍스 또는 수지 입자가 2상으로 존재하게 되고, 결과적으로 저장안정성을 떨어뜨리는 문제점이 있다.When actually manufacturing the coating waterproofing agent of the different composition as described above, the asphalt particles and rubber-based latex or resin particles are present in two phases, and as a result, there is a problem of lowering the storage stability.

다시말해, 종래 도막방수제의 제조방법은 아스팔트를 투입하고, 스티렌-부타디엔 라텍스 등을 투입한 다음, 여기에 유화제를 투입하여 결과적으로 유화된 아스팔트 입자와 고무입자가 각기 존재하게 된다.In other words, in the conventional method for producing a film waterproofing agent, asphalt is added, styrene-butadiene latex or the like is added thereto, and an emulsifier is added thereto, resulting in the presence of the emulsified asphalt particles and rubber particles.

이와같이 아스팔트 입자와 고무입자가 각기 존재하는 고무아스팔트 도막방수제는 통상 고형분 함량 85% 정도의 제품으로 유통되며, 실제 사용시 묽혀서 사용하게 되는 바, 각기 다른 상으로 존재하기 때문에 저장안정성이 떨어지는 문제점이 발생된다.As such, the rubber asphalt coating waterproofing agent, in which asphalt particles and rubber particles are present, is usually distributed as a product having a solid content of about 85%, and when used in actual use, they are diluted and used. do.

본 발명의 목적은 상기와 같은 종래 고무아스팔트 도막방수제의 저장안정성 문제점을 해결하기 위한 것으로, 아스팔트를 100∼150℃로 용융시킨 다음, 여기에 라텍스 또는 수지를 끓어넘치지 않는 속도로 서서히 투입하여 완전히 혼화되도록 하여 저장안정성이 향상된 고무아스팔트 도막방수제의 제조방법을 제공하는 데 있다.An object of the present invention is to solve the storage stability problem of the conventional rubber asphalt coating film waterproofing agent as described above, and melt the asphalt to 100 ~ 150 ℃, then slowly added at a rate that does not boil the latex or resin to it completely mixed The present invention provides a method for preparing a rubber asphalt coating waterproofing agent having improved storage stability.

이와같은 목적을 달성하기 위한 본 발명의 고무아스팔트 도막방수제의 제조방법은 아스팔트 250∼300 중량부를 100∼150℃에서 서서히 교반하여 수용화하는 단계; 상기 수용화된 아스팔트에 고무 라텍스 또는 수지 70∼110 중량부를 0.5∼1.5시간에 걸쳐 투입한 다음 20∼50rpm으로 교반하는 단계; 로진산염 0.5∼3.0 중량부와 올레인산염 0.05∼0.5 중량부를 투입하고 균일하게 분산시키는 단계; 및 이온교환수를 투입하여 고형분 함량 50∼90% 되도록 제조하는 단계로 이루어진다.Method for producing a rubber asphalt coating film waterproofing agent of the present invention for achieving the above object comprises the steps of solubilizing 250 to 300 parts by weight of asphalt at 100 to 150 ℃; Adding 70 to 110 parts by weight of rubber latex or resin to the accommodated asphalt over 0.5 to 1.5 hours and then stirring at 20 to 50 rpm; Adding 0.5 to 3.0 parts by weight of rosin and 0.05 to 0.5 parts by weight of oleate and dispersing it uniformly; And by adding ion-exchanged water it comprises the step of producing a solid content of 50 to 90%.

본 발명의 고무아스팔트 도막방수제를 제조하는 방법을 상세히 설명하면 다음과 같다.Referring to the method for producing a rubber asphalt coating waterproofing agent of the present invention in detail as follows.

먼저, 아스팔트 250∼300 중량부를 100∼150℃에서 서서히 교반하여 수용화한다. 여기서, 아스팔트로는 통상의 것을 사용할 수 있는 바, 바람직하게는 AP-3를 사용하는 것이다. 아스팔트를 수용화하는 데 있어서, 교반시 온도가 상기 범위 보다 높으면 아스팔트가 끓어넘치는 문제가 발생될 수 있다.First, 250 to 300 parts by weight of asphalt are gradually stirred at 100 to 150 ° C. to be solubilized. As the asphalt, a conventional one can be used, and preferably, AP-3 is used. In accepting the asphalt, if the temperature at the time of stirring is higher than the above range, the asphalt may boil.

상기와 같이 수용화된 아스팔트에 통상 고무계 도막방수제에 사용되는 라텍스 또는 수지를 첨가하는 바, 라텍스 또는 수지의 첨가시 서서히 투입하여야 하며 교반속도도 지나치게 빠르면 끓어넘치게 되는 바, 투입시 시간은 0.5∼1.5시간에 걸쳐 투입하는 것이 바람직하고 교반속도는 20∼50rpm인 것이 바람직하다.As latex or resin is usually added to the above-mentioned asphalt-based waterproofing agent, it should be added slowly when the latex or resin is added. If the stirring speed is too fast, it will boil. It is preferable to add over time, and the stirring speed is preferably 20 to 50 rpm.

상기와 같이 100∼150℃ 온도를 유지하면서 아스팔트와 라텍스 또는 수지를 혼화하는 경우 물이 증발되면서 라텍스 또는 수지가 아스팔트에 완전히 녹아들어가게 된다.As described above, when mixing asphalt and latex or resin while maintaining the temperature of 100 to 150 ° C., the latex or resin is completely dissolved in the asphalt while water is evaporated.

라텍스로는 스티렌-부타디엔 라텍스를 사용할 수 있고, 수지로는 아크릴계 폴리머를 사용할 수 있다.Styrene-butadiene latex may be used as the latex, and an acrylic polymer may be used as the resin.

이와같이 완전 혼화된 상태에 유화제를 첨가하는 바, 본 발명에서는 유화제로서 로진산염과 올레인산염을 혼합하여 첨가한다.In this way, an emulsifier is added to the completely mixed state. In the present invention, rosin and oleate are mixed and added as an emulsifier.

이때, 로진산염 0.5∼3.0 중량부와 올레인산염 0.05∼0.5 중량부를 투입하고 균일하게 분산시킨다.At this time, 0.5 to 3.0 parts by weight of rosin and 0.05 to 0.5 parts by weight of oleate are added and uniformly dispersed.

이와같이 유화제를 균일하게 분산시키면, 아스팔트와 라텍스 또는 수지의 균일혼합물과 유화제가 균일하게 분산된 상태로 존재하며, 여기에 이온교환수를 첨가한다.When the emulsifier is uniformly dispersed in this way, the homogeneous mixture of the asphalt and latex or resin and the emulsifier are present in a uniformly dispersed state, and ion-exchanged water is added thereto.

이온교환수로는 pH를 10∼11로 조정한 것을 사용하는 바, pH의 조정은 수산화나트륨을 0.1∼0.2 중량부 첨가하는 방법을 통해 수행된다.As ion-exchanged water, a pH adjusted to 10 to 11 is used. The pH is adjusted by adding 0.1 to 0.2 parts by weight of sodium hydroxide.

이와같이 pH가 조절된 이온교환수를 첨가하면 전기적 현상으로 안정화되며, 라텍스 또는 수지와 아스팔트의 균일 혼합물을 얻을 수 있게 된다.Thus, the addition of pH adjusted ion-exchanged water is stabilized by the electrical phenomenon, it is possible to obtain a homogeneous mixture of latex or resin and asphalt.

만일, pH가 상기 범위를 벗어나는 경우 유화된 입자의 안정성이 파괴되어 다량의 찌꺼기가 생성되는 문제점이 발생될 수 있다.If the pH is out of the above range, the stability of the emulsified particles may be destroyed to generate a large amount of dregs.

이하, 본 발명을 실시예에 의거 상세히 설명하면 다음과 같은 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited by the Examples.
