That is, the composition of the sealant is unsaturated polyester (olsophthalic acid, isophthalic acid, bisphenol type) resin, vinyl ester or epoxy acrylate resin with different polybasic acids and glycol molar ratios, sieving pigments, pigmented pigments, dispersion additives, sedimentation inhibitors , Aromatic and ketone solvents, accelerators, and curing agents. And the detection line protection sealant is characterized in that it is not only easy to bond with asphalt and cement concrete roads, but also melts in spring or summer when the temperature is high, and protects the detection line from vehicle traffic.
종래의 검지선 보호용 시멘트 콘크리트의 홈 충진제는 습도에 의해 건조가 지연되고 피치의 홈 충진제는 높은 기온에 의해 녹아내려 검지선이 노출되고 경화시간이 너무 늦어 교통체증이 발생하여 차량통행속도가 빠르지 못하는 등 불편과 경제적인 손실이 많이 발생하였다.Conventional groove line fillers in cement concrete for protecting the detection line are delayed by humidity and the groove filler in the pitch is melted due to high temperature, so that the detection line is exposed and the curing time is too late, resulting in traffic jam due to the traffic jam. There were many economic and economic losses.
본 발명은 이와같은 종래의 문제점을 개선한 것으로 체질안료, 유색안료 및 용제 조성등 검지선과 부착성을 증가시키는 종류를 주종으로 하여 설계하고, 실란트에 사용되는 수지 또한 아스팔트 및 시멘트 콘크리트 도로에 대한 부착성이 우수하며 높은 온도에 의해 안정하고 속경화로 인하여 작업성이 월등한 효과를 얻을수 있다.The present invention is to improve the conventional problems such as sieving pigments, colored pigments and solvent composition mainly designed to increase the adhesion and the type of adhesion, the resin used in the sealant is also attached to the asphalt and cement concrete road It is excellent in stability, stable by high temperature, and has excellent workability due to fast curing.

The connection line from the loop sensor to the connection part is called the loop induction wire, and the connection line from the connection part to the detector device in the field controller at the intersection is called the loop cable, and these are collectively called the detection line.
검지선을 설치하기 위해서 아스팔트 및 시멘트 콘크리트 도로 표면에 폭 0.9-1.5 cm, 깊이 5-10 cm 정도를 카타(Cutter)로서 제거시키고 절단한 홈 부위에 고인물이나 절단잔재물을 깨끗하게 제거시킨 다음 홈 부위에 검지선을 매설시키며 아스팔트 및 시멘트 콘크리트 도로에 통행하는 많은 차량으로부터 매설된 검지선이 파손되는 것을 막기 위해서 검지선의 최외곽에 보호용 시멘트 및 피치를 홈 충진용으로 사용한다. 이 때 홈에 충진된 시멘트는 건조속도가 느리며 검지선과의 접착력이 떨어지는 단점이 있으며, 피치는 기온이 높은 봄, 여름에 녹아내려 검지선이 노출되기 때문에 파손되면서 차량통행의 지장을 초래하여 그 본래의 기능을 발휘할 수 없는 경우가 있다.To install the detection line, remove 0.9-1.5 cm in width and 5-10 cm in depth on the surface of asphalt and cement concrete roads with a cutter, and remove any debris or residues from the cut area. To protect the buried detection lines from damage from many vehicles that pass on the asphalt and cement concrete roads, the protective cement and pitch are used for the filling of the grooves on the outermost side of the detection lines. At this time, the cement filled in the groove has a disadvantage of slow drying speed and poor adhesion to the detection line.The pitch is melted in spring and summer when the temperature is high and the detection line is exposed, which causes damage to the vehicle traffic. It may not be possible to function.
따라서 본 발명은 아스팔트 및 시멘트 콘크리트 도로에 매설한 검지선이 도로상으로 노출되지 않도록 하기 위해서 홈 충진을 할 수 있는 검지선 보호용 실란트 조성물과 그 제조 방법을 제공한 것이다.Accordingly, the present invention provides a detection line protective sealant composition and a method of manufacturing the same that can be filled with a groove so that the detection line embedded in the asphalt and cement concrete road is not exposed on the road.
먼저 국내에서 널리 사용되고 있는 검지선 보호용 실란트로서 모래에 시멘트를 일정한 비율로 혼합한 후 물로 희석하여 사용하는 홈 충진용 시멘트를 들 수 있다. 또 하나는 코올타르에서 휘발성분을 증류하여 남은 찌꺼기의 피치를 사용한 홈 충진제를 들 수 있다. 이러한 두가지 유형의 홈 충진제는 다음과 같은 단점을 가진다.First, as a sealant protection sealant widely used in Korea, there is a home filling cement which is used by diluting cement with sand and diluting it with water. Another one is a home filler using the pitch of the residue left after distilling volatiles from the coal tar. These two types of groove fillers have the following disadvantages.
첫째, 시멘트를 사용하는 홈 충진제는 아스팔트 및 시멘트콘크리트 도로에 매설된 검지선과의 접착력이 약하여 시멘트가 검지선을 보호하지 못하여 떨어지기 쉽다. 또한 이 시멘트는 물을 다량 사용하기 때문에 건조 속도 및 작업성이 느리도록 설계되어 있다. 이는 홈 충진한 시멘트가 쉽게 파손될 뿐만 아니라 건조속도가 현저히 느리기 때문에 차량통행의 흐름을 방해하여 교통체증을 유발시키기도 한다.First, the home fillers using cement have a weak adhesive strength with the detection line embedded in the asphalt and cement concrete roads, and thus the cement cannot easily protect the detection line. In addition, the cement is designed to have a low drying rate and workability due to the large amount of water used. This not only easily breaks the cement filled with the grooves, but also slows down the drying speed, thus preventing traffic flow and causing traffic jams.
둘째, 피치를 사용하는 홈 충진제는 아스팔트 및 시멘트 콘크리트 도로에 매설된 검지선과의 접착력은 있지만 피치의 경도가 유연하기 때문에 건조속도가 느리고, 통행하는 차량의 타이어에 부착하여 떨어져 나올 뿐만 아니라 기온이 높은 계절에 피치가 녹아내려 검지선과 홈 부위가 도로의 표면에 나타난다. 이는 홈 충진한 피치가 도로에서 떨어져 나와 검지선이 노출됨과 동시에 차량통행속도에 지장을 초래한다.Secondly, the groove filler using pitch has adhesion to the detection line embedded in asphalt and cement concrete roads, but because the pitch hardness is flexible, the drying speed is slow, and it is attached to the tire of the passing vehicle, and it falls off as well as the temperature is high. During the season, the pitch melts and the detection line and grooves appear on the road surface. This causes the groove-filled pitch to fall off the road, exposing the detection line, and at the same time affecting the speed of the vehicle.
위의 두가지 홈 충진제는 이러한 단점을 가지고 있기 때문에 본 발명자는 심사숙고하여 도로교통안전협회 및 경찰청 관련 규격에 적합하면서도 아스팔트 및 시멘트 도로의 검지선 보호용 실란트가 절실히 필요하게 되었다. 따라서 본 발명자는 이러한 종래 기술의 단점을 심도 있게 연구하여 위에서 열거한 두가지 종류의 홈 충진제가 가지고 있는 문제점을 해결 할 수 있는 새로운 검지선 보호용 실란트를 발명하게 되었다.Since the above two home fillers have such disadvantages, the present inventors have been deliberated, and the sealant for protecting the detection line of the asphalt and cement roads is desperately needed to meet the standards related to the Road Traffic Safety Association and the National Police Agency. Therefore, the present inventors have studied the shortcomings of the prior art in depth to invent a new detection line protection sealant that can solve the problems of the two types of home fillers listed above.
본 발명에 따른 검지선 보호용 실란트 조성물은 불포화 폴리에스테르 수지, 비닐에스테르 수지 또는 에폭시 아크릴레이트 수지 30 ∼ 50 중량%, 체질안료 30 ∼ 40 중량%, 유색안료 5 ∼ 10 중량%, 침강방지제 0.25 ∼ 0.75 중량%, 분산첨가제 0.25 ∼ 0.75 중량%, 방향족계 용제(스틸렌 모노머 포함) 5 ∼ 15 중량%, 케톤계 용제 5 ∼ 10 중량%, 코발트계 경화촉진제 0.5 ∼ 1.5 중량%로 구성되는 것을 특징으로 한다.Detection liner sealant composition according to the present invention is 30 to 50% by weight unsaturated polyester resin, vinyl ester resin or epoxy acrylate resin, 30 to 40% by weight sieving pigment, 5 to 10% by weight pigment, pigment settling agent 0.25 to 0.75 weight %, 0.25 to 0.75 wt% of a dispersing additive, 5 to 15 wt% of an aromatic solvent (including styrene monomer), 5 to 10 wt% of a ketone solvent, and 0.5 to 1.5 wt% of a cobalt-based curing accelerator.
본 발명에 따른 바인다 조성물은 다염기산과 글리콜 몰비가 다른 불포화 폴리에스테르 수지 30 ∼ 50 중량%를 포함한다. 상기 불포화 폴리에스테르 수지가 30 중량% 이하이면 실란트의 유동성이 떨어져 접착력이 약하고 60 중량% 이상이면 상대적으로 체질안료 및 첨가제의 함량이 작아져 실란트의 점도 조정이 어렵고 제조상의 문제점이 발생되어 바람직하지 않다. 본 발명에서 사용할 수 있는 불포화 폴리에스테르 수지에는 올소프탈릭 에시드타입(이하 올소타입이라 한다), 이소프탈릭 에시드 타입 (이하 이소타입이라 한다), 비스페놀 타입 수지와 비닐에스테르 또는 에폭시 아크릴레이트 수지의 함량이 30 ∼ 50 중량%로 이들 수지는 여러 가지 종류의 모노머로부터 합성해서 사용한다.The binder composition according to the present invention comprises 30 to 50% by weight of unsaturated polyester resins having different polybasic acids and glycol molar ratios. If the unsaturated polyester resin is less than 30% by weight, the fluidity of the sealant is poor, and the adhesive strength is weak. If the unsaturated polyester resin is more than 60% by weight, the content of the extender pigment and the additive is relatively small, making it difficult to adjust the viscosity of the sealant, which is not preferable due to manufacturing problems. . Unsaturated polyester resins that can be used in the present invention include an allophthalic acid type (hereinafter referred to as an olsotype), an isophthalic acid type (hereinafter referred to as an isotype), a bisphenol type resin and a vinyl ester or epoxy acrylate resin. At 30 to 50% by weight, these resins are synthesized from various kinds of monomers and used.
본 발명에 따른 검지선 보호용 실란트 조성물은 통상적인 체질안료 30 ∼ 40 중량%를 포함한다. 체질안료는 규소함량이 55%이상인 일신활석사의 탈크로 흡습성이 우수하며 화학적으로 안정하여 산, 알카리에 반응하거나 용해되지 않은 것을 사용한다. 체질안료가 30 중량% 이하이면 실란트의 은폐력이 약해지고 40 중량% 이상이면 점도가 상승하여 실란트의 제조공정 및 시공상의 작업성이 떨어져 바람직하지 못하다.The detection line protective sealant composition according to the present invention contains 30 to 40% by weight of conventional extender pigments. Sieving pigments are excellent in hygroscopicity with talc of ilsin talcum sand containing 55% or more of silicon and are chemically stable and do not react or dissolve in acids and alkalis. If the extender pigment is 30 wt% or less, the hiding power of the sealant is weak, and if it is 40 wt% or more, the viscosity is increased, which is undesirable because of poor workability in the manufacturing process and construction of the sealant.
본 발명에서는 검지선 보호용 실란트 조성물로 유색안료는 듀폰사의 이산화티탄늄 R-900 으로 5 ∼ 10 중량%를 사용한다. 안료의 함량이 5 중량% 이하이면 실란트의 착색력이 떨어져 색상이 선명하지 못하고 10 중량% 이상이면 색상은 선명하나 상대적으로 코스트가 증가하므로 경제성이 떨어진다.In the present invention, the colored pigment is used in the detection line protective sealant composition, 5-10% by weight of titanium dioxide R-900 manufactured by DuPont. If the content of the pigment is less than 5% by weight, the coloring power of the sealant is not clear, and the color is not clear.
본 발명에서 실란트의 침강현상을 방지시키기 위해 투명한 결정체의 유기점토의 분말로 사용될 수 있는 침강방지제는 칙소 겔 (미국 SUD-캠)이 0.25 ∼ 0.75 중량%를 포함한다. 침강방지제의 함량이 0.25 중량% 이하이면, 장기간 보관할 때 실란트가 침강할 뿐만 아니라 케이크가 형성되어 유동성을 잃어버리고, 0.75 중량% 이상이면 칙소성이 증가하고 점도가 상승하여 실란트의 작업성이 떨어진다.In order to prevent the sedimentation of the sealant in the present invention, the anti-settling agent, which can be used as a powder of organic clay of transparent crystals, contains 0.25 to 0.75% by weight of thixogel gel (US SUD-CAM). If the content of the anti-settling agent is 0.25% by weight or less, not only the sealant is settled during long-term storage but also the cake is formed and loses fluidity. If the content is more than 0.75% by weight, the thixotropy increases and the viscosity increases, resulting in poor workability of the sealant.
본 발명에서 수지, 체질안료, 유색안료의 혼합물에 첨가하여 원하는 규정 입도까지 분산할 수 있는 조제로 장쇄 포리아미노아마이드와 고분자산 에스테르의 염인 안티테라-유 (독일 BYK)가 0.25 ∼ 0.75 중량%를 포함한다. 분산제의 함량이 0.25 중량% 이하이면, 분산시간이 오래 걸려 균일한 입도를 얻었을 수 없고, 0.75 중량% 이상이면 입도는 균일하게 얻을 수 있으나 필요 이상으로 첨가하게 됨으로서 경제적으로 코스트가 상승하게 된다.In the present invention, an anti-terra oil (Germany BYK), which is a salt of a long-chain polyaminoamide and a high molecular acid ester, is added to the mixture of resin, extender pigment and colored pigment to disperse to a desired particle size. Include. If the content of the dispersant is 0.25% by weight or less, it may not be possible to obtain a uniform particle size due to a long dispersing time. If the content of the dispersant is 0.75% by weight or more, the particle size may be uniformly obtained.
본 발명에서는 방향족계 용제 5 ∼ 15 중량%를 사용한다. 방향족계 용제가 5 중량% 이하이면, 실란트 홈 충진막의 평활성이 떨어지고 15 중량% 이상이면, 실란트의 점도가 떨어져서 바람직하지 않다. 본 발명에서 사용할 수 있는 방향족계 용제로서 스틸렌 모노머 또는 톨루엔의 혼합용제를 들수 있다.In this invention, 5-15 weight% of aromatic solvents are used. If the aromatic solvent is 5 wt% or less, the smoothness of the sealant groove filling film is lowered, and if it is 15 wt% or more, the viscosity of the sealant is inferior, which is not preferable. As an aromatic solvent which can be used by this invention, the mixed solvent of a styrene monomer or toluene is mentioned.
본 발명에서 케톤계 용제는 5 ∼ 10 중량%를 사용한다. 케톤계 용제가 5 중량% 이하이면 실란트의 점도가 상승하게 되고 10 중량% 이상이면 실란트의 침강이 발생한다. 사용할 수 있는 케톤계 용제로서는 메틸에틸케톤 또는 메틸이소부틸케톤 등 하나 또는 두가지의 혼합물로서 사용할 수 있다.In the present invention, the ketone solvent is used 5 to 10% by weight. If the ketone solvent is 5% by weight or less, the viscosity of the sealant is increased, and if it is 10% by weight or more, the sealant is settled. As a ketone solvent which can be used, it can be used as one or two mixtures, such as methyl ethyl ketone or methyl isobutyl ketone.
본 발명에서 경화촉진제는 코발트 나프테네이트 금속염(금속함량 5%)으로 0.5 ∼ 1.5 중량%로 구성된다. 0.5 중량% 이하이면 경화 촉진이 느리게 진행되고 1.5 중량% 이상이면 경화 촉진이 너무 빠르게 진행되어 작업성이 떨어진다.In the present invention, the curing accelerator is composed of 0.5 to 1.5% by weight of cobalt naphthenate metal salt (metal content 5%). If it is 0.5 weight% or less, hardening promotion will progress slowly, and if it is 1.5 weight% or more, hardening promotion will progress too fast and workability will fall.
