Abstract
Description
본 발명은 폴리에스터 수지를 포함하는 도로 표지용 도료 및 이를 이용한 도색 공법에 관한 것이다. 보다 구체적으로, 본 발명은 통상적인 도료에 열가소성 수지인 폴리에스터를 첨가하여 얻어진 도로 표지용 도료 및 이를 이용한 아스팔트 도로에 대한 융착식 도로 표지 도색 공법에 관한 것으로, 본 발명에 따른 도료는 도로면과의 부착성이 높고, 노면에 사용되는 유리비드의 부착성을 높여 내구성을 증진시키므로 휘도를 유지하고, 융착식에 사용되는 석유수지의 연화를 방지하고 도로 표지의 갈라지는 현상을 방지함으로 도로 표지의 내구성을 증진시키는 도료 및 이를 이용한 도색 공법에 관한 것이다.The present invention relates to a road marking paint containing a polyester resin and a painting method using the same. More specifically, the present invention relates to a road marking paint obtained by adding polyester, which is a thermoplastic resin, to a conventional paint, and a fusion-type road marking painting method for asphalt roads using the same. It has high adhesion, and improves durability by increasing the adhesion of glass beads used on the road surface, which maintains brightness, prevents softening of petroleum resin used in fusion type, and prevents cracking of road signs. It relates to a paint to improve the paint and a coating method using the same.
도료 표지 도색 공법에는 융착식, 상온식, 가열식 시공방법이 있으며, 이 중 가장 높은 내구성을 얻을 수 있는 시공방법인 융착식 시공방법이 도로 표지 도색을 위하여 널리 이용되고 있다. 융착식 도로 표지 도색 공법은 분말형 도료를 융행기라는 기계장치를 이용하여 높은 증기압으로 가열하고, 도색기를 통하여 노면에 도 색하여 실시된다. 분말형 도료가 가열되어 노면에 도색되면 뜨거운 열이 아스팔트 표면층을 녹이면서 석유 성분층들이 접착성을 띄게 되고 이로 인하여 아스팔트 표면과 도료가 접착성을 띄게 되는 것이다. 따라서, 석유 성분을 포함하는 아스팔트 노면의 경우 석유 성분을 포함하지 않은 콘크리트나 시멘트 노면과는 달리 노면 상의 간단한 먼지제거 및 이물질 제거만으로도 노면 상에 도색된 도로 표지가 우수한 부착성 및 내구성을 가질 수 있다. 그러나, 아스팔트 도로에 도색된 경우라 하더라도 시간이 경과함에 따라 상당 부분이 습기에 의해 부착력이 약화되어 도료가 쉽게 이탈되고 마모되어 선명도를 잃어버리며 우천 시나 야간 운행 시 도로식별에 어려움이 있다는 문제점도 있었다. There are fusion coating, room temperature, and heating construction methods for paint label painting. A fusion construction method, which is the construction method that can obtain the highest durability, is widely used for painting road markings. Fusion-type road marking painting is performed by heating powder-type paint at high vapor pressure using a machine called an air blower, and painting the road surface through a paint machine. When the powder paint is heated and painted on the road surface, hot heat melts the asphalt surface layer, and the petroleum component layers become adhesive, thereby making the asphalt surface and the paint adhesive. Therefore, in the case of asphalt roads containing petroleum, unlike concrete or cement roads that do not contain petroleum, road markings painted on the road surface may have excellent adhesion and durability with only simple dust removal and debris removal. . However, even when painted on asphalt roads, as the time passes, a large part of the adhesive strength is weakened by moisture, so that the paint is easily released and worn away, and the sharpness is lost. .
또한, 통상적인 도로 표지 도색 공정에서는 도로 표지용 도료를 도포하고, 그 위로 유리비드를 살포하는 공정을 이용하고 있으나 이 경우 살포된 유리비드가 잘 탈락하는 문제가 있다.In addition, in the conventional road marking painting process, the coating for the road marking coating is applied, and the glass beads are sprayed thereon, but in this case, there is a problem in that the sprayed glass beads drop off well.
도로 표지 도색 방법에 관한 선행 기술 문헌 중 하나인 특허등록 공고 제89-5084호에서는 염화 고무수지, 카듀라 변성 아크릴 수지, 비스페놀계 에폭시 첨가제를 바인더로 포함하는 내알카리성 프라이머를 도장한 후 도료를 도장하는 도로 표지 도색 방법을 개시하고 있다. 이러한 공정의 경우 도료 도색 공정 이전에 프라이머 도장 공정이 선행되어야 하므로 인건비를 포함한 시공비가 많이 소요된다.Patent Registration Publication No. 89-5084, which is one of the prior art documents on the road sign painting method, applies an alkali resistant primer containing a chlorinated rubber resin, a cardura-modified acrylic resin, and a bisphenol-based epoxy additive as a binder. A road sign painting method is disclosed. In such a process, since the primer coating process must be preceded before the paint painting process, a lot of construction costs including labor costs are required.
한편, 특허등록 10-0686207의 경우 노면에 접착제를 도포한 다음 접착제가 도포된 노면에 유리비드를 부착하고 부착된 비드를 다짐한 후 최종적으로 도료를 도포하는 도로 표지 도색방법을 개시하고 있다. On the other hand, Patent Registration 10-0686207 discloses a road sign painting method for applying an adhesive to the road surface, and then attaching glass beads to the road surface to which the adhesive is applied, compacting the attached beads and finally applying paint.
상기 특허문헌에 기재된 공법은 유리비드의 탈락을 방지하기 위하여 접착제를 사용하고 있는 것을 특징으로 하고 있으나, 접착제 도포에 따른 추가 공정으로 인하여 재료비 및 인건비가 증가하므로 경제적이지 못하다는 단점을 가지고 있다.The method described in the patent document is characterized in that the adhesive is used to prevent the falling of the glass bead, but has the disadvantage that it is not economical because the material cost and labor costs increase due to the additional process according to the adhesive coating.
이에 본 발명자들은 번거로운 추가 공정 없이 한 단계의 공정만으로 도로 표지를 도색할 수 있을 뿐만 아니라, 도로 표지에 도포된 유리비드의 탈락율이 매우 낮고 도색된 도로 표지의 접착성 및 내구성이 매우 높은 도로 표지용 도료 및 이를 이용한 도로 표지 도색 공법을 제공하고자 하였다. Therefore, the present inventors can not only paint a road sign in one step without cumbersome additional processes, but also have a very low dropout rate of glass beads applied to the road signs and a high adhesiveness and durability of the painted road signs. To provide a paint and a road marking painting method using the same.
본 발명은 아스팔트 도로면에 시공되어 높은 내구성을 나타낼 수 있는 융착식 도로 표지용 도료를 제공하기 위한 것이다.The present invention is to provide a coating for fusion-type road marking that can be constructed on the asphalt road surface can exhibit high durability.
또한, 본 발명은 추가 공정없이 한 단계의 도포 공정만으로도 도색된 도로 표지의 접착성 및 내구성을 향상시킬 수 있는 융착식 도로 표지용 도료를 제공하기 위한 것이다.In addition, the present invention is to provide a coating for a fusion road marking that can improve the adhesion and durability of the painted road sign without a single step without further processing.
또한, 본 발명은 기존의 융착식 도로 표지용 도료의 주성분인 석유수지와 혼용이 잘 되면서 열에도 강한 폴리에스터를 도로 표지용 도료에 혼합하여 도로 표지로서 도포함으로써 유리비드의 탈락을 방지하고 도로면과의 접촉을 강화하여 도로 표지의 내구성을 증진시키기 위한 도로 표지 도색공법을 제공하기 위한 것이다. In addition, the present invention is well mixed with the petroleum resin which is the main component of the conventional fusion-type road coating paint and mixed with a strong heat resistant polyester to the road marking paint to prevent falling of glass beads and road surface It is to provide a road sign painting method for enhancing the durability of the road sign by enhancing the contact with.
본 발명은 융점이 160∼180℃이고 중량평균분자량이 16,000~18,000인 불휘발성 폴리에스터 수지를 포함하는 도로 표지용 도료를 제공하는 것이다. The present invention provides a road marking paint containing a nonvolatile polyester resin having a melting point of 160 to 180 ° C and a weight average molecular weight of 16,000 to 18,000.
또한, 본 발명은 본 발명에 따른 도로 표지용 도료를 180 내지 220℃로 승온하여 도로 표지를 도색하는 융착식 도로 표지 도색 방법을 제공하는 것이다.In addition, the present invention is to provide a fusion-type road marking painting method for painting a road sign by heating the road marking paint according to the present invention to 180 to 220 ℃.
본 발명은 간단한 시공으로 아스팔트 도로면에 높은 접착성 및 내구성을 나타낼 수 있는 도로 표지용 도료를 제공한다. 본 발명에 따른 도료는 특정한 폴리에스터를 포함함으로써 노면에 부착된 유리비드의 부착성을 증진시켜 장시간 동안 휘 도를 유지하고, 도료의 주성분인 석유수지의 연화를 방지하고, 또한 도로 표지의 갈라짐 현상을 방지함으로써 도로 표지의 내구성을 증진시킬 수 있다. The present invention provides a road marking paint that can exhibit high adhesion and durability to the asphalt road surface by a simple construction. The paint according to the present invention includes a specific polyester to improve the adhesion of the glass beads adhered to the road surface to maintain the brightness for a long time, to prevent the softening of the petroleum resin, the main component of the paint, and also the cracking phenomenon of the road sign It can improve the durability of the road sign by preventing the.
본 명세서에서 “도로 표지”란 차선, 주차선, 횡단보도, 과속방지턱 등을 포함하여 도로 또는 건설 현장의 표지를 널리 포함하는 것으로 해석된다.As used herein, “road sign” is construed to broadly include a sign of a road or construction site, including lanes, parking lines, pedestrian crossings, speed bumps, and the like.
본 명세서에서 “도로 표지용 도료”란 차선, 주차선, 횡단보도, 과속방지턱 등 광범위한 도로 또는 건설 현장의 표지를 나타내기 위하여 사용되는 도색용 도료를 널리 포함하는 것으로 해석된다.As used herein, the term “road marking paint” is interpreted to broadly include a paint for marking a road, a parking line, a pedestrian crossing, a speed bump, and a wide range of road or construction marks.
본 발명의 첫 번째 면은 융점이 160∼180℃이고 중량평균분자량이 16,000~18,000인 불휘발성 폴리에스터 수지를 포함하는 도로 표지용 도료를 제공하는 것이다. The first aspect of the present invention is to provide a road marking paint comprising a nonvolatile polyester resin having a melting point of 160 to 180 ° C. and a weight average molecular weight of 16,000 to 18,000.
도로 표지용 도료에 첨가되는 불휘발성 폴리에스터의 함량은 2~10중량%, 바람직하기는 2~6중량%, 가장 바람직하기는 2~4중량%인 것이다. 도료에 포함되는 불휘발성 폴리에스터 수지 함량이 2중량% 미만인 경우 접착력 및 내마모성이 떨어지며, 폴리에스터 함량이 높아질수록 접착력 및 내마모성은 증가하지만 10중량%를 넘는 경우 원가 상승 요인이 되므로 바람직하지 않다. 불휘발성 폴리에스터 수지가 2 내지 6중량% 포함될 때 비용 대비 최고의 접착력을 나타내며, 경제성을 고려할 때 가장 바람직한 함량은 2 내지 4중량%인 것이다. The content of the nonvolatile polyester added to the road marking paint is 2 to 10% by weight, preferably 2 to 6% by weight, most preferably 2 to 4% by weight. When the content of the nonvolatile polyester resin included in the paint is less than 2% by weight, the adhesion and the wear resistance are lowered, and as the polyester content is increased, the adhesion and the wear resistance is increased, but when it exceeds 10% by weight, it is not preferable because it increases the cost. When the non-volatile polyester resin is included 2 to 6% by weight it shows the best adhesion to the cost, the most preferable content is 2 to 4% by weight in consideration of economics.

The polyester resin according to the present invention has good compatibility with petroleum resin, which is a main component of a general road marking paint, and has a fast adhesion speed and a wide range of adhesion. Epoxy or urethane resins are not suitable because they have a low melting point and cause gelation when mixed with paint.
본 발명에서는 상기한 특징을 갖는 불휘발성 폴리에스터 수지를 통상적인 도로 표지용 도료에 2 내지 10중량% 함량으로, 보다 바람직하기는 2 내지 6중량% 함량으로 혼합하여 사용한다. 본 발명에 따른 도로 표지용 도료에 있어서 베이스 도료는 시판 중인 융착식 도료 표지용 도료라면 특별히 제한되지 않는다. In the present invention, the nonvolatile polyester resin having the above characteristics is used in a mixture of 2 to 10% by weight, and more preferably 2 to 6% by weight, in a conventional road marking paint. In the paint for road marking according to the present invention, the base paint is not particularly limited as long as it is a commercially available fusion paint labeling paint.
본 발명에 따른 도로 표지용 도료는 통상적으로 융착식 도로 표지 도색 공법에 사용되는 도료에 상기한 폴리에스터 수지를 포함하는 것을 특징으로 한다. 통상적인 융착식 도로 표지용 도료는 석유수지, 산화티타늄, 탄산칼슘, 무기 안료, 유기 안료, 또는 유리비드로부터 선택되는 하나 이상의 성분을 포함한다. 상기 성분의 함량은 특별히 제한되지 않으며 당업자에 의하여 적절히 조절될 수 있다. 도료 중 유리비드 함유량 또한 특별히 제한되지 않는다.The paint for road marking according to the present invention is characterized in that it comprises the polyester resin mentioned above in the paint normally used for the fusion-type road marking painting method. Typical fused road marking paints include one or more components selected from petroleum resins, titanium oxides, calcium carbonates, inorganic pigments, organic pigments, or glass beads. The content of the component is not particularly limited and may be appropriately adjusted by those skilled in the art. Glass bead content in the paint is also not particularly limited.
