Description
본 발명은 히드로 카본형(hydrocarbon) 오일과 열가소성 엘라스토머(TPE, Themoplastic Elastomer)가 첨가된 아스팔트를 기재로 한고무화아스팔트 도막방수제 및 그의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber-based asphalt coating waterproofing agent based on asphalt to which a hydrocarbon oil and a thermoplastic elastomer (TPE) are added, and a manufacturing method thereof.
종래의 고무화아스팔트 도막방수제는 단순히 아스팔트에 고무가 첨가된 것으로서 아스팔트 단독으로는 가질 수 없는 성질, 즉 신장율, 내균열성 및 내한성을 갖게 되었지만, 강도 및 경도가 부족하고, 기온이 높은 여름철에는 녹아 흘러 내리며, 추운 겨울철에는 경화될 뿐만 아니라 시간이 경과됨에 따라, 즉 자연증발이나 분해로 인해 아스팔트중의 유분이 탈유되어 점차 그의 신장율이 감소되며 내구성 및 내후성도 감소되는 결점이 있다.Conventional rubberized asphalt coating waterproofing agent is simply rubber added to asphalt, which has properties that asphalt alone cannot have, e.g. elongation, crack resistance and cold resistance, but lacks strength and hardness, and melts in high temperatures. Flowing down, in addition to curing in the cold winter, as time passes, that is, the oil in asphalt due to spontaneous evaporation or decomposition deoils gradually decreases its elongation rate and durability and weather resistance also has the drawback.
본 발명은 아스팔트에 히드로 카본형 오일을 첨가함으로서 유분의 탈유를 방지하거나 보완하여 내구성 및 내후성을 개선하고, 또한 가소제, 보강제 및 노화방지제를 사용하여 도막방수제의 강도 및 경도를 증진시키며 고무가루외에 열가소성 엘라스토머를 혼합함으로서 도막방수제로서 중요한 특성인 신장을, 내균열성 및 내한성을 상당히 보강하여 본 발명을 완성하기에 이르렀다.The present invention improves durability and weather resistance by preventing or supplementing oil deoiling by adding hydrocarbon oil to asphalt, and also using plasticizers, reinforcing agents and anti-aging agents to enhance the strength and hardness of the coating waterproofing agent and to add thermoplastics to rubber powder. By mixing the elastomers, elongation, which is an important characteristic as a coating waterproofing agent, is considerably strengthened, and crack resistance and cold resistance have been strengthened to complete the present invention.
따라서, 본 발명은 종래의 고무화아스팔트 도막방수제에서 문제가 되고 있는 제특성을 증진시키거나 보완하여 여름철에는 녹아 내리지 않고 겨울철에는 경화되지 않는 등 전천후로 사용될 수 있는 우수한 특성을 가진 고무화아스팔트 도막방수제를 제공하는 것이다.Accordingly, the present invention improves or supplements the properties that are a problem in the conventional rubberized asphalt coating waterproofing agent, so that it does not melt in the summer and does not harden in the winter, such as rubberized asphalt coating waterproofing agent having excellent properties that can be used in all weather To provide.
본 발명의 고무화아스팔트 도막방수제는 아스팔트 70중량부에 히드로 카본형 오일 5중량부, 가소제 4중량부, 보강제 10중량부, 및 소량의 노화방지제가 첨가되고, 이에 더하여 열가소성 엘라스토머 10중량부와 고무가루 5중량부가 충진된 우수한 특성을 가진 고무화아스팔트 도막방수제이다.Rubberized asphalt coating waterproofing agent of the present invention is added 5 parts by weight of hydrocarbon oil, 4 parts by weight of plasticizer, 10 parts by weight of reinforcing agent, and a small amount of antioxidant, 70 parts by weight of asphalt, in addition to 10 parts by weight of thermoplastic elastomer and rubber It is a rubberized asphalt coating waterproofing agent having excellent properties filled with 5 parts by weight of powder.
본 발명에서 사용된 아스팔트는 통상의 아스팔트가 사용될 수 있으나 스트레이트 아스팔트가 바람직하며 특히 그 아스팔트의 침입도가 60~80정도인 것이 가장 이상적이다. 히드로 카본형 오일은 일반적으로 아스팔트와 혼화성이 좋은 것이 사용되나 본 발명에서는 방향족유가 39.5%, 파라핀유가 31.5% 및 나프틴유가 29%로 함유된 오일을 사용한다. 히드로 카본형 오일의 첨가량은 도막방수제의 적절한 유분 함량을 유지하는데 필요한 양이다.Asphalt used in the present invention may be used as conventional asphalt, but straight asphalt is preferred, especially the penetration of the asphalt is about 60 ~ 80 is most ideal. Hydrocarbon-type oils are generally compatible with asphalt, but in the present invention, oils containing 39.5% of aromatic oils, 31.5% of paraffin oils and 29% of naphthene oils are used. The amount of hydrocarbon oil added is an amount necessary to maintain an appropriate oil content of the coating waterproofing agent.
고무를 유연하게 하는데 필요한 가소제로서는 합성고무와 상용성이 좋은 디옥틸플탈레이트 (DOP, Dioctyl Phthalate)를 사용하는 것이 바람직하나, 고무가소제로서 알려져 있는 디옥틸아디페이트, 디옥틸세바케이트, 디메틸프탈레이트 등도 사용될 수 있다. 이러한 가소제의 사용량은 가소 효과를 얻는데 충분하며 4중량부가 바람직하다. 보강제로서는 고무공업에서 사용되고 있는 경질 탄산 칼슘이 사용되며 노화방지제로서는 히드로퀴논 모노벤질 에테르가 적합하며 그 사용량은 2중량부이하로 사용되는 것이 바람직하다.It is preferable to use dioctyl phthalate (DOP, Dioctyl Phthalate) which is highly compatible with synthetic rubber as the plasticizer required to soften the rubber, but dioctyl adipate, dioctyl sebacate, dimethyl phthalate and the like which are known as rubber plasticizers are also used. Can be used. The amount of such plasticizer used is sufficient to obtain a plasticizing effect, and 4 parts by weight is preferable. As the reinforcing agent, hard calcium carbonate used in the rubber industry is used, and as the anti-aging agent, hydroquinone monobenzyl ether is suitable, and its amount is preferably used in an amount of 2 parts by weight or less.
한편, 열가소성 엘라스토머는 스티렌-부타디엔, 스티렌-부타디엔-스티렌, 스티렌-이소프렌-스티렌, 스티렌-에틸렌-부타디엔-스티렌등 여러가지가 있으나 이중에서 아스팔트와 상용성이 좋은 스티렌-부타디엔-스티렌(SBS)이 바람직하며, 특히 스티렌과 부타디엔의 함량비가 3:7인것이 보다 바람직하며, 결합 방식이 가교결합인 것이 더욱 바람직하다. 그러나, 가교율이 너무 높으면 아스팔트와 중합시에 가교결합을 분리하는데 많은 에너지가 소모되며, 즉 온도가 놓아야하기 때문에 오히려 아스팔트의 물성을 저해할 우려가 있어서 가교율이 약 30%인것이 좋다. 고무가로로서는 페타이어를 이용하며 약 30메쉬 이상으로 잘게 부순것을 사용하는 것이 좋다.The thermoplastic elastomers include styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene-styrene, styrene-ethylene-butadiene-styrene, and among these, styrene-butadiene-styrene (SBS) having good compatibility with asphalt is preferable. In particular, the content ratio of styrene and butadiene is more preferably 3: 7, and more preferably, the bonding mode is crosslinking. However, if the crosslinking rate is too high, a lot of energy is consumed to separate the crosslinking during the polymerization with asphalt, that is, since the temperature must be set, there is a risk of inhibiting the physical properties of the asphalt. As a rubber street, use a pet tire and finely crush it to about 30 mesh or more.
본 발명의 또다른 일예에서는 상기에 제시된 조성을 가진 고무화아스팔트 도막방수제의 제조방법이 제공된다. 본 발명의 제조방법은 아스팔트를 가열하여 히드로 카본형 오일을 첨가한 후, 가소제, 보강제 및 노화방지제를 혼합시키고, 이어서 열가소성 엘라스토머와 고무가루를 충진시켜 180-200oC까지 가열하고 교반하는 것으로 이루어진다.In another embodiment of the present invention there is provided a method for producing a rubberized asphalt coating film waterproofing agent having the composition shown above. The production method of the present invention consists of heating the asphalt to add hydrocarbon oil, mixing the plasticizer, the reinforcing agent and the anti-aging agent, and then filling the thermoplastic elastomer with the rubber powder to heat and stir to 180-200 ° C. and stir. .
실시예Example
반응기에 침입도가 60-70정도 되는 아스팔트 70중량부를 넣고 150-180oC로 가열한다. 여기에 히드로 카본형 오일(방향족유 39.5%, 파라핀유 31.5% 및 니프틴유 29%로 구성됨) 5중량부를 첨가하고, 이어서 DOP 4중량부, 경질 탄산 칼슘 10중량부 및 히드로퀴논 모노벤질 에테르 2중량부를 넣고 5분동안 교반한 다음, TPE 10중량부와 고무가루 5중량부를 넣고 200oC까지 가열하며 30분 정도 교반한다.Insert 70 parts by weight of asphalt having a penetration of about 60-70 and heat it to 150-180 ° C. To this was added 5 parts by weight of hydrocarbon oil (comprising 39.5% of aromatic oil, 31.5% of paraffin oil and 29% of nitinine oil), followed by 4 parts by weight of DOP, 10 parts by weight of hard calcium carbonate and 2 parts by weight of hydroquinone monobenzyl ether. After stirring for 5 minutes, 10 parts by weight of TPE and 5 parts by weight of rubber powder is added and heated to 200 o C and stirred for about 30 minutes.
TPE가 모두 용해되면 스테인레스 판에 도포하여 시편을 제작하였다.Once all the TPE was dissolved, it was applied to a stainless plate to prepare a specimen.
