Abstract
Description
본 발명은 열가소성 엘라스토마(TPE)가 함유된 고무화 아스팔트 도막방수재의 제조방법에 관한 것이다. 보다 구체적으로 말하자면, 본 발명은 가소제가 첨가된 아스팔트에 TPE를 용해시킨다음 쿠마론인덴수지와 충진제로서 고무가루를 첨가시켜 강도 및 경도가 높을뿐만 아니라 접착력과 고형분 함량이 증진된 고무화 아스팔트 도막방수제의제조방법에 관한 것이다.The present invention relates to a method for producing a rubberized asphalt coating waterproofing material containing thermoplastic elastomer (TPE). More specifically, the present invention dissolves TPE in asphalt to which plasticizers are added, and then adds rubber powder as a coumarone indene resin and a filler to increase rubber strength and hardness, as well as to improve adhesion and solid content. It relates to a manufacturing method.
종래의 고무화 아스팔트 도막방수재는 아스팔트에 고무를 첨가하므로서 아스팔트가 가질수 없는 성질, 즉 우수한 신장율, 내균열성, 내한성을 갖게 되었지마는 강도 및 경도가 부족하여 도막재로서 요구하는 물성을 충족시켜 주질 못했다. 또한 자연건조 또는 강제건조시 경화시간의 지연이나 경화제 사용으로 인한 원성을 상승과 이로 인한 물성의 저하를 초래한다는 단점이 있었다.Conventional rubberized asphalt coating waterproofing material has not been able to meet the properties required as coating material due to the lack of strength and hardness due to the addition of rubber to asphalt, which asphalt cannot have, that is, excellent elongation, crack resistance, and cold resistance. . In addition, natural drying or forced drying had a disadvantage of increasing the originality due to the delay of curing time or the use of a curing agent and deterioration of physical properties.
본 발명은 이와 같은 종래의 도막방수제가 갖는 단점들을 보완하기 위하여 도막방수제의 제조공정에 제품의 탄성을 향상시킬 수 있는 TPE를 첨가시킴으로서 아스팔트와 첨가된 TPE의 분자가 결합을 증진시키며 또한 접착력을 증가시키는 쿠마론 인데수지를 첨가함으로서 종래의 도막방수제가 가지는 장점외에도 강도 및 경도가 높고 접착력이 우수할 뿐만 아니라 TPE의 발열속도가 빨라 도막형성이 용이하며 따라서 공사기간을 휠씬 단축시킬 수 있는 도막방수제 및 이의 제조방법을 제공하는데 목적이 있다.The present invention is to supplement the disadvantages of the conventional film waterproofing agent by adding a TPE that can improve the elasticity of the product in the manufacturing process of the film waterproofing agent to enhance the bond between the asphalt and the added TPE and also increase the adhesion In addition to the advantages of conventional coating waterproofing agent by adding coumarone resin, the coating film waterproofing agent has high strength and hardness, excellent adhesion, and rapid heat generation rate of TPE, thus making it easy to form a coating film and thus shortening construction period. It is an object to provide a method for producing the same.
본 발명의 제조방법은 150-180℃로 가열된 아스팔트에 가소제로서 디옥틸프탈레이트(DOP)를 첨가한다음 180℃로 유지시키면서 쿠마론 인데수지와 TPE를 넣어 용해시킨다음 충진제로서 고무가루를 넣어 교반시키는 것으로 이루어진다.The manufacturing method of the present invention adds dioctylphthalate (DOP) as a plasticizer to asphalt heated to 150-180 ° C, while maintaining it at 180 ° C to dissolve the couron indeon resin and TPE, and then put rubber powder as a filler and stirred It consists of.
본 발명의 제조방법에서 쿠마론 인데수지는 사용된 아스팔트의 총중량을 기초로 10-25중량%를 첨가하는 것이 바람직하다. 또한 TPE는 아스팔트 총중량 기초로 TPE가 20중량% 이하일 때 고무성분의 부족으로 신장률, 강도등이 저하되며 반면에 TPE가 30중량% 보다 클 때 아스팔트에 대한 결합효율이 떨어지므로, 20-30중량%로 첨가하는 것이 바람직하다.In the production method of the present invention, it is preferable to add 10-25% by weight based on the total weight of the asphalt used. In addition, when TPE is less than 20% by weight based on the total weight of asphalt, the elongation and strength of the TPE decreases due to the lack of a rubber component, whereas when the TPE is greater than 30% by weight, the binding efficiency to the asphalt is lowered. It is preferable to add by.
본 발명의 제조방법에서 사용하는 아스팔트는 스트레이트 아스팔트, 블로운 아스팔트, 아스팔트 콤파운드등이 있으나 침입도가 60-80정도의 스트레이트 아스팔트가 가장 우수하다.Asphalt used in the production method of the present invention is a straight asphalt, blown asphalt, asphalt compound, etc., but the most excellent straight asphalt with a penetration of about 60-80.
또한 고무를 유연하게 해주는 고무가소제로는 디옥틸아디페이트, 디옥틸세바케이트 디메틸프탈레이트 디옥틸프탈레이트 등이 사용되나 특히 합성고무와 상용성이 양호한 디옥틸프탈레이트를 사용하는 것이 좋다.In addition, dioctyl adipate and dioctyl sebacate dimethyl phthalate dioctyl phthalate are used as rubber plasticizers to soften rubber, but dioctyl phthalate having good compatibility with synthetic rubber is preferable.
TPE로서는 스틸렌-부타디엔(SB), 스틸렌-부타디엔-스틸렌(SBS), 스틸렌·이소프렌·스틸렌(SIS),스틸렌-에틸렌-부타디엔-스틸렌(SEBS) 등 여러 가지가 있으나 아스팔트와 사용성이 가장 우수한 SBS를 사용하는 것이 좋다. SBS 중에서도 스틸렌과 부타디엔의 함량비가 30:70인 것이 좋으며 스틸렌과 부타디엔이 30%정도 가교결합된 것이 더욱좋다. 이와 같은 이유는 쇄상결합력이 약함에 따라 도막재의 제물성을 기대하기 어려우나 가교결합은 결합방식의 특성상 아스팔트와중합이 되어도 강도 및 경도가 높게 나타나기 때문이다. 그러나 가교율이 너무 높으면 아스팔트와 중합시 고온이 필요하여 열에 약한 아스팔트의 물성저하를 가져오므로 30% 정도가 적당하다.There are various kinds of TPE such as styrene-butadiene (SB), styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS), styrene-ethylene-butadiene-styrene (SEBS), but SBS which has the best usability with asphalt It is good to use. Among SBS, the content ratio of styrene and butadiene is preferably 30:70, and more preferably 30% crosslinking of styrene and butadiene. The reason for this is that it is difficult to expect the physical properties of the coating material due to the weak chain binding force, but crosslinking is high in strength and hardness even when polymerized with asphalt due to the nature of the bonding method. However, if the crosslinking rate is too high, high temperature is required for polymerization with asphalt, which results in weak physical properties of asphalt, which is weak to heat.
본 발명의 제조방법에서 결합력 증진에 사용되는 수지는 석유수지와 쿠마론 인덴수지가 사용가능하나 스틸렌 함량이 10%, 인덴함량이 30% 정도인 쿠마론 인데수지가 적당하며 고무가루는 50메쉬부터 15메쉬까지 사용할 수 있으나 30메쉬정도가 적당하다. 고무가루의입도가 크면 표면이 거칠어 물성이 저하되고 입도가 작은 경우 열에 의해 고무가루가 분해되어 충진제로서의 역할을 할 수 없다.The resin used to improve the bonding strength in the production method of the present invention can be used as petroleum resin and coumarone indene resin, but the styrene content is 10%, the indene content is about 30% coumarone resin is suitable and the rubber powder from 50 mesh Up to 15 meshes can be used, but about 30 meshes are suitable. If the particle size of rubber powder is large, the surface is rough and physical properties are deteriorated. If the particle size is small, rubber powder is decomposed by heat, and thus it cannot serve as a filler.
본 발명을 실시예를 들어 좀더 자세하게 설명하면 다음과 같다.The present invention will be described in more detail with reference to Examples.
[실시예]EXAMPLE
반응기에 침입도가 60-70정도 되는 스트레이트 아스팔트를 195중량부를 넣고 180℃로 가온한다. 여기에 고무가소제로 디옥틸프탈레이트 9중량부를 넣고 180℃를 계속 유지하면서 5분정도 교반한다. 그 후 쿠마론 인데수지 30중량부를 넣고 10분정도 교반시켜 완전히 용해시킨다. 온도를 200℃로 높인후 SBS 45중량부를 넣고 30분간 교반시켜 완전히 녹인 다음 온도를 150℃로 낮춘후 고무가루를 21중량부 투입한다. 이때 너무 갑작스런 투입은 고무가루에 포함된 공기의 열팽창에 의해 돌비현상이 일어나므로 서서히 투입시켜야 한다.195 parts by weight of straight asphalt having a penetration of about 60-70 is added to the reactor and warmed to 180 ° C. 9 parts by weight of dioctylphthalate was added to the rubber plasticizer, and the mixture was stirred for about 5 minutes while maintaining the temperature at 180 ° C. Then add 30 parts by weight of coumarone indeon resin and stir for 10 minutes to dissolve completely. After raising the temperature to 200 ℃, add 45 parts by weight of SBS and stir for 30 minutes to completely dissolve, lower the temperature to 150 ℃ and 21 parts by weight of rubber powder. At this time, too sudden input should be added slowly because dolby phenomenon occurs due to thermal expansion of air contained in rubber powder.
이와 같이 약 20분정도 충진시켜 잘 교반시킨 다음 스테인레스판에 도포하여, 시편을 제작하고 또한 시판중인 도막방수제로서 JGCOAT(상품명, 중앙방수기업 주식회사제, 경도 10)를 사용하여 동일하게 시편을 제작한다음 이에 대한 물성을 측정하여 비교하면 다음의 표 1과 같은 결과를 얻을 수 있었다.After filling for about 20 minutes and stirring well, it was applied to a stainless plate to prepare a specimen, and the same specimen was produced using JGCOAT (trade name, manufactured by Central Waterproofing Co., Ltd., hardness 10) as a commercial coating waterproofing agent. Next, by comparing and measuring the physical properties thereof, the results as shown in Table 1 below were obtained.
