Abstract
Description
본 발명은 색상발현이 우수하고 높은 내균열성을 갖는 경관포장용 칼라아스콘에 관한 것이다. 경관포장은 차량이 다니는 도로에 대규모로 이루어지기도 하지만, 안전지역을 표시하기 위한 학교주변(스쿨존) 또는 굴곡도로, 그리고 미적효과를 위한 공원보도, 산책로, 운동경기장, 호텔, 쇼핑센터 등에 소규모로도 시공된다. The present invention relates to a color ascon for landscape packaging having excellent color expression and high crack resistance. Landscape pavement is sometimes done on a large-scale road where vehicles travel, but on a small scale around schools (school zones) or winding roads to mark safe areas, and park walkways, trails, sports fields, hotels, and shopping centers for aesthetic effects. It is also constructed.
일반적으로 경관포장은 시멘트 콘크리트, 아스팔트 콘크리트(아스콘), 고무칩, 에폭시, 우레탄 등 여러 종류의 포장이 있다. 이들 포장은 모두 장단점이 있는데, 예를 들면 시멘트 콘크리트는 강성은 있지만 시멘트 콘크리트 자체의 시멘트 비산으로 인한 환경적인 문제와 색상을 발현하기 어려워서 포장후 안료를 추가로 도색하야 하는 단점이 있다. 이와 같이 추가로 안료를 도색하는 경우 자동차 바퀴와의 마찰로 인해 색상이 쉽게 없어지는 문제점이 있다. In general, landscape pavement includes various types of pavement such as cement concrete, asphalt concrete (ascon), rubber chips, epoxy, and urethane. All of these pavements have advantages and disadvantages, for example, although cement concrete has rigidity, it is difficult to express environmental problems and color due to the scattering of cement of the cement concrete itself, so there is a disadvantage that additional pigments must be painted after paving. When the pigment is additionally painted as described above, there is a problem in that the color is easily lost due to friction with the vehicle wheel.
대한민국 등록특허 제 10-1047284 호에서는 통상의 칼라아스콘 포장체 코팅용 기능성 광촉매 조성물 및 그 조성물을 코팅한 기능성 칼라아스콘 포장체에 대해서 기재하고 있다. Korean Patent Registration No. 10-1047284 describes a functional photocatalyst composition for coating a conventional color ascon package and a functional color ascon package coated with the composition.
또한, 대한민국 등록특허 제 10-0580787 호에서는 수용성 아크릴 수지 10 내지 50 중량%, 착색안료 분산체 5 내지 15 중량%, 수용성 에폭시 수지 1 내지 10 중량%, 색 분리 방지제, 소포제, 표면 조정제, 침전방지제, 부틸셀로솔브 및 트리에틸아민으로 이루어진 군으로부터 선택된 적어도 하나의 첨가제 01 내지 10 중량% 및 여분의 물을 포함하는 칼라아스콘 표면 코팅제 조성물에 대해서 기재하고 있다. In addition, in Korean Patent Registration No. 10-0580787, 10 to 50% by weight of a water-soluble acrylic resin, 5 to 15% by weight of a colored pigment dispersion, 1 to 10% by weight of a water-soluble epoxy resin, an inhibitor of color separation, an antifoaming agent, a surface adjuster, an anti-settling agent , Butyl cellosolve and triethylamine, at least one additive selected from the group consisting of 01 to 10% by weight, and the color ascon surface coating composition comprising excess water.
상기 종래의 특허는 칼라아스콘의 색상보존, 대기정화, 바오성 등을 부여하기 위하여 칼라아스콘 포장체의 표층에 코팅하는 기술이다. 그러나 차량, 특히 대형차량이 많이 통행하는 중교통로에서 표층이 마손되어 칼라아스콘의 내구성이 떨어지는 문제점이 있다. The conventional patent is a technology for coating the surface of the color ascon package to impart color preservation, air purification, and antifouling properties to the color ascon. However, there is a problem in that the durability of the color ascon is deteriorated due to the wear of the surface layer in the heavy traffic road where a lot of vehicles, especially large vehicles pass.
또한, 고무칩, 에폭시, 우레탄을 이용한 경관포장은 색상의 발현은 우수하지만, 재료 특성상 시공표면의 평탄성을 유지하기가 어려울뿐만 아니라 내후성이 약하고 바인더가 경화되면서 수축이 일어나기 때문에 포장체에 균열(크랙) 또는 벌어짐 현상이 발생되는 단점이 있다. In addition, the exterior pavement using rubber chips, epoxy, and urethane has excellent color expression, but it is difficult to maintain the flatness of the construction surface due to the nature of the material, and it is weak in weather resistance and shrinkage occurs as the binder cures, so cracks (cracks) in the package. ) Or flaring phenomenon occurs.
또한 칼라아스콘은 일반적으로 빨강, 파랑, 노랑, 또는 녹색을 발현하기 위하여 주로 무색 바인더를 사용하는데, 이러한 무색 바인더는 석유수지, 가소제, 열가소성 고무 등으로 이루어져 있어 이들 성분의 낮은 내후성으로 인해 내균열성 및 내구성이 떨어지는 문제점이 있다. In addition, color ascons generally use colorless binders to express red, blue, yellow, or green color. These colorless binders are made of petroleum resin, plasticizer, and thermoplastic rubber. And there is a problem of poor durability.
이러한 내균열성 및 내구성 문제 때문에, 어쩔수 없이 검정색의 일반 아스팔트(AP)를 바인더로 사용하게 되는데, 이러한 검정색의 일반 아스팔트는 색상 발현에 난점이 있다. 원하는 색상을 구현하기 위해 상대적으로 과대하게 많은 안료를 사용하게 되어 칼라아스콘의 생산비용을 증가시킨다.Because of these crack resistance and durability problems, black general asphalt (AP) is inevitably used as a binder, and such black general asphalt has a difficulty in color expression. It increases the production cost of color ascon by using a relatively excessive amount of pigment to realize the desired color.
따라서, 기존의 아스팔트를 사용함으로써 내균열성 및 내구성을 유지한채 안료의 혼입량을 줄이고서도 우수한 색상을 오랜 기간동안 발현할 수 있는 경관포장용 칼라아스콘을 필요로 하는 상황에 있다.Therefore, there is a need for a color ascon for landscape pavement that can express excellent color for a long period of time while maintaining crack resistance and durability by using existing asphalt, while reducing the amount of pigment mixed.
본 발명의 목적은 기존의 아스팔트를 사용할 때 내균열성 및 내구성을 높이면서 안료 본래의 색상을 오랜 기간동안 우수하게 발현할 수 있는 경관포장용 칼라 아스콘을 제공하는데 있다.It is an object of the present invention to provide a color asphalt concrete for landscape pavement that can exhibit excellent color of the original pigment for a long period while improving crack resistance and durability when using conventional asphalt.

본 발명에서 사용되는 굵은골재의 크기는 입경이 6 mm 이상이며, 잔골재는 입경이 6 mm 미만인 것이다. 굵은 골재는 본 발명의 경관포장용 칼라아스콘에 대하여 40∼60 중량부 사용되는 것이 바람직하고, 잔골재는 35∼50 중량부 사용되는 것이 바람직하다. The size of the coarse aggregate used in the present invention has a particle diameter of 6 mm or more, and the fine aggregate has a particle diameter of less than 6 mm. The coarse aggregate is preferably used in an amount of 40 to 60 parts by weight, and a fine aggregate is preferably used in an amount of 35 to 50 parts by weight based on the color ascon for landscape packaging of the present invention.
본 발명의 경관포장용 칼라아스콘에 사용되는 주된 바인더는 아스팔트로서 일반 경관포장용에는 AP-5(PG 64-22)의 규격제품을 사용하며, 재활용 경관포장용에는 기본적으로 AP-3(PG-58-22)를 사용하며, 대형 차량이 많이 통행하는 중교통로의 개질아스팔트나 고속도로에 특화되어 있는 PSMA 등에 사용되는 개질 아스팔트 AP(PG7622, 82-22)를 사용하여 색상을 발현할 수 있다. 다만 재활용 경관포장용에 AP-5(PG 64-22)를 사용하는 경우, 재활용 첨가제의 투입량이 거의 1.5배 이상 사용한다. The main binder used in the color ascon for landscape pavement of the present invention is asphalt, and the standard product of AP-5 (PG 64-22) is used for general landscape pavement, and AP-3 (PG-58-22) is basically used for recycled landscape pavement. ), and the modified asphalt AP (PG7622, 82-22), which is used for the modified asphalt of heavy transport roads where large vehicles pass, or the PSMA specialized for expressways, can be used to express color. However, in case of using AP-5 (PG 64-22) for recycled landscape packaging, the amount of recycled additive is used almost 1.5 times or more.
본 발명에 사용되는 바인더의 양은 경관포장용 칼라아스콘의 100 중량부에 대하여 4∼6 중량부 사용되는 것이 바람직하다. 정확한 바인더의 사용량은 아스콘의 배합설계에 따라서 골재의 입도를 고려하여 혼합물의 공극율을 감안하여 정한다. The amount of the binder used in the present invention is preferably 4 to 6 parts by weight based on 100 parts by weight of color ascon for landscape packaging. The exact amount of binder used is determined in consideration of the porosity of the mixture in consideration of the particle size of the aggregate according to the mixing design of ascon.
본 발명에서 섬유첨가제는 셀룰로오즈 화이버와 합성섬유를 사용할 수 있으며, 두 섬유 모두 길이는 1∼3 mm이고, 직경이 0.05∼0.6 mm인 섬유를 사용한다. 또한 이 두 종류의 아스콘의 생산온도는 전자의 아스콘보다 높고 전반적으로 온도의 분포가 안정적이어서 펠릿(Pellet) 형태의 섬유를 사용하며 섬유첨가제의 함량은 경관포장용 칼라아스콘의 0.1∼0.5 중량부를 사용한다. 그 사용량이 0.1 중량부 미만이면 저온크랙 등의 저온물성 강화에 효과가 없으며, 0.5 중량부를 초과하면 섬유의 뭉침현상과 초과적인 바인더가 필요하게 되어 바인더 과다현상을 초래하게 된다. In the present invention, cellulose fibers and synthetic fibers may be used as the fiber additive, and both fibers have a length of 1 to 3 mm and a diameter of 0.05 to 0.6 mm. In addition, the production temperature of these two types of ascon is higher than that of the former, and the overall temperature distribution is stable, so pellet-type fibers are used, and the content of fiber additives is 0.1 to 0.5 parts by weight of color ascon for landscape packaging. . If the amount is less than 0.1 parts by weight, there is no effect on reinforcing low-temperature properties such as low-temperature cracks, and if it exceeds 0.5 parts by weight, agglomeration of fibers and an excess binder are required, resulting in an excessive binder.
본 발명의 경관포장용 칼라아스콘에 사용되는 개선안료는 무기안료 상에 무기안료의 중량에 대하여 코팅제를 30∼50 중량부의 비율로 코팅한 후, 상기 코팅제 상에 무기안료의 중량에 대하여 다시 피막박리방지제를 0.1∼0.5 중량부를 도포한 다음, 별도로 분산제 1∼2 중량부를 혼합하고, 이어서 40∼80 메쉬의 분말 형태로 제조한다. The improved pigment used in the color ascon for landscape packaging of the present invention is coated with a coating agent on the inorganic pigment in a ratio of 30 to 50 parts by weight based on the weight of the inorganic pigment, and then the coating agent is again coated on the coating agent with respect to the weight of the inorganic pigment. 0.1 to 0.5 parts by weight of is applied, and then 1 to 2 parts by weight of a dispersant are separately mixed, and then prepared in the form of a powder of 40 to 80 mesh.
본 발명의 경관포장용 칼라아스콘에 사용되는 무기안료로는 산화철(Fe2O3), 산화티탄(TiO2), 산화크롬(Cr2O3), 코발트 화합물((Co3AsO4)2ㆍ8H2O) 등이 있다. 도 1에 도시한 바와 같이, 종래에는, 이들 안료(2)는 아스팔트(1)보다 상대적으로 비중이 높아서 상기 안료(2)가 아스팔트 내에 분산될 때 아스팔트(1)의 하부에 집중된다. 따라서 칼라아스콘의 표층 부분에서 보다 선명한 색상을 발현하기 위해서는 더 많은 양의 안료(2)를 혼입하여야 한다. 이와 같이 많은 양의 안료(2)를 사용하여야 하므로 비용상승의 원인이 된다. The inorganic pigments used in the color ascon for landscape packaging of the present invention include iron oxide (Fe 2 O 3 ), titanium oxide (TiO 2 ), chromium oxide (Cr 2 O 3 ), and cobalt compounds ((Co 3 AsO 4 ) 2 ㆍ8H. 2 O) and so on. As shown in FIG. 1, conventionally, these
본 발명에서는 산화철, 산화티탄, 산화크롬, 코발트 화합물 등과 같이 비중이 높은 무기안료에 상대적으로 낮은 비중을 갖는 코팅제로서 PE(융점 110∼115℃), PP(융점 165℃), EVA(융점 54∼74℃), 석유수지(융점 70∼100℃) 등의 수지를 무기안료의 중량에 대하여 30∼50 중량부의 비율로 코팅한다. 그리고 상기와 같이 무기안료의 코팅층 위에 다시 피막박리방지제를 무기안료의 중량에 대하여 0.1∼0.5 중량부를 도포한다. 마지막으로 상기 피막박리방지제로 도포된 무기안료에 분산제를 상기 무기안료의 중량에 대하여 1∼2 중량부를 투입한 후 0.2∼0.4cm의 펠릿 형태로 본 발명에 따른 개선안료를 제조한다. 바람직하기로는 이를 다시 40∼80 메쉬의 분말 형태로 개선안료를 제조한다. In the present invention, as a coating agent having a relatively low specific gravity for inorganic pigments having a high specific gravity such as iron oxide, titanium oxide, chromium oxide, and cobalt compounds, PE (melting point 110 to 115°C), PP (melting point 165°C), EVA (melting point 54 to 74°C), petroleum resin (melting point 70 to 100°C), etc. are coated in a ratio of 30 to 50 parts by weight based on the weight of the inorganic pigment. And as described above, 0.1 to 0.5 parts by weight of the anti-film peeling agent is again applied on the coating layer of the inorganic pigment based on the weight of the inorganic pigment. Finally, 1 to 2 parts by weight of a dispersant is added to the inorganic pigment coated with the anti-film peeling agent, and then the improved pigment according to the present invention is prepared in the form of 0.2 to 0.4 cm pellets. Preferably, it is again prepared in the form of a powder of 40 to 80 mesh to improve the pigment.
상기 개선안료는 1차적으로 길이 0.2∼0.4cm의 펠릿 형태의 알갱이로 가공하여 사용하기도 하며, 2차적으로 가공을 통해서 40∼80 메쉬의 분말(파우더) 형태로 재가공하여 제조된다. 2단계로 가공을 하는 이유는 경관포장용 혼합물이 투입되는 일차가공제품은 2형태상 혼합물을 혼합하는 시간과 온도가 충분하지 않아 혼합물 전체기간 내에 혼합물 전체에 걸쳐 분산성이 떨어지기 때문이다. The improved pigment is primarily processed into pellets having a length of 0.2 to 0.4 cm and used, and is produced by secondary processing to form a powder (powder) of 40 to 80 mesh. The reason for processing in two stages is that in the primary processed product into which the mixture for landscape packaging is added, the time and temperature for mixing the two-form mixture are insufficient, so that the dispersibility is poor throughout the entire mixture within the entire mixture period.
펠릿과 파우더 형태의 안료는 장단점을 갖고 있다. 펠릿 형태의 안료는 아스콘 혼합물의 믹싱 시간과 온도가 충분하지 않는 혼합물을 가공하는 경우에 정해진 조건 안에서 혼합 믹서 내부에 전반적으로 분산되기 힘든 단점을 갖고 있지만, 재료의 자체 무게로 인하여 혼합 과정중에 비산되어 손실되지 않는 장점을 갖고 있다. 파우더는 그 반대라고 보면 이해할 수 있으며, 이러한 이유로 개선안료의 선택은 중요도와 여건에 맞추어 결정된다. Pigments in the form of pellets and powders have advantages and disadvantages. The pigment in the form of pellets has the disadvantage that it is difficult to disperse overall inside the mixing mixer within the specified conditions when the mixing time and temperature of the ascon mixture is not sufficient, but due to the weight of the material, it is scattered during the mixing process. It has the advantage of not being lost. It can be understood that powder is the opposite, and for this reason, the choice of an improvement pigment is determined according to the importance and conditions.
도 2에 도시한 바와 같이, 2차 가공된 개선안료는 비중이 낮은 고분자 코팅제(3)로 코팅되어 있기 때문에 무기안료(2)만의 높은 비중을 아스팔트(1) 정도의 비중으로 낮추어 줌으로써 아스팔트(1)에 균일하게 분산된다. 따라서 본 발명의 경관포장용 칼라아스콘은 무기안료만을 사용하는 종래의 칼라아스콘보다도 적은양의 안료를 사용할 수 있으며, 반복되는 차량통과에 의한 표면 마손에도 시공 처음과 동일하게 맑고 선명하게 색상을 발현할 수 있다. As shown in FIG. 2, since the secondary processed improvement pigment is coated with a polymer coating agent (3) having a low specific gravity, the high specific gravity of the inorganic pigment (2) is reduced to the specific gravity of asphalt (1). ) Is evenly distributed. Therefore, the color ascon for landscape packaging of the present invention can use a smaller amount of pigment than the conventional color ascon, which uses only inorganic pigments, and can express the color clearly and clearly as in the beginning of construction even in surface wear caused by repeated vehicle passages. have.
일반 경관포장재용 개선안료는 원하는 색상에 따라 산화철(적색, 노랑, 오렌지색), 산화티탄(백색), 산화크롬(녹색), 및 코발트(파란색)로부터 선택된 무기안료 35∼55 중량부에 코팅제 30∼50 중량부의 비율로 코팅된다. 코팅제는 LLDPE(110∼115℃ 융점) 30∼55 중량%, EVA 25-40 중량%, 및 PP 25-35 중량%로 구성되는 것이 바람직하다. Improvement pigments for general landscape packaging materials are 30 to 55 parts by weight of inorganic pigments selected from iron oxide (red, yellow, orange), titanium oxide (white), chromium oxide (green), and cobalt (blue) depending on the desired color. It is coated in a proportion of 50 parts by weight. The coating agent is preferably composed of 30-55% by weight of LLDPE (110-115°C melting point), 25-40% by weight of EVA, and 25-35% by weight of PP.
본 발명의 개선안료에 사용되는 분산제로는 석유수지가 바람직하며, 개선안료에 대해 1∼2 중량부의 양으로 포함된다. 그 함량이 1 중량부 미만인 경우에는 개선안료가 아스팔트에서의 분산성이 떨어지며, 2 중량부를 초과하면 석유수지의 저온물성에 취약한 점이 전체 혼합물에 영향을 주게 된다. Petroleum resin is preferable as the dispersant used in the improvement pigment of the present invention, and is included in an amount of 1 to 2 parts by weight based on the improvement pigment. If the content is less than 1 part by weight, the improved pigment dispersibility in asphalt is poor, and if it exceeds 2 parts by weight, the weak point of the low-temperature properties of the petroleum resin affects the entire mixture.
본 발명의 개선안료에 사용되는 피막박리방지제로는 아민계 화합물이 바람직하며, 예를 들면 2개의 지방족 1차 아민과 3개의 지방족 2차 아민으로 구성된 테트라에틸렌펜타아민, 트리에틸렌테트라아민(TEPA) 또는 비스(헥사메틸렌)트리아민(BHMT)을 사용하며 무기안료에 코팅된 코팅제가 박리되지 않게 하여 색상발현 효과를 오랜 기간동안 유지시켜준다.An amine-based compound is preferable as the film peeling inhibitor used in the improvement pigment of the present invention, for example, tetraethylenepentaamine and triethylenetetraamine (TEPA) composed of two aliphatic primary amines and three aliphatic secondary amines. Alternatively, bis(hexamethylene)triamine (BHMT) is used and the coating agent coated on the inorganic pigment does not peel off, thereby maintaining the color expression effect for a long period of time.
본 발명의 개선안료는 기존의 무기질 안료가 갖는 아스팔트보다 높은 비중을 갖는 문제점을 개선하여 개발되었으며, 검은색의 아스팔트 내에서 분산성을 높이고 무기안료 자체 비중보다 낮추기 위해서 경관포장재의 생산온도인 170∼180℃에서 용융이 잘되는 고분자 물질인 코팅제와 분산제를 배합하여 제조된다. The improved pigment of the present invention was developed by improving the problem of having a higher specific gravity than that of the existing inorganic pigments, and in order to increase dispersibility in black asphalt and lower than the specific gravity of the inorganic pigment itself, the production temperature of landscape packaging material is 170~ It is manufactured by mixing a coating agent and a dispersant, which is a polymer material that melts well at 180°C.
