Description
본 발명은 도로포장용 수용성 아크릴-에폭시 모르타르 및 이를 이용한 도로 포장방법에 관한 것으로, 좀 더 구체적으로는 아스팔트 포장된 도로의 표면에 문자, 기호 및/또는 숫자 등의 소정의 문양을 홈 형태로 형성한 다음, 상기 아스팔트에 수용성 아크릴-에폭시 모르타르를 도포하여 미관이 수려하고, 시인성 및 친환경성을 향상시킬 수 있는 도로포장용 수용성 아크릴-에폭시 모르타르 및 이를 이용한 도로 포장방법에 관한 것이다.The present invention relates to a water-soluble acrylic-epoxy mortar for road pavement and a road pavement method using the same. More specifically, a predetermined pattern such as letters, symbols, and / or numbers is formed on the surface of an asphalt-paved road in the form of a groove. Next, the present invention relates to a water-soluble acrylic-epoxy mortar for road pavement, which can apply a water-soluble acrylic-epoxy mortar to the asphalt, improves visibility and environmental friendliness, and a road paving method using the same.
일반적으로 보행로 또는 도로 등에 적용되는 콘크리트 및 아스팔트 포장재의 표면에는 방향유도기호나 제한속도표시 등을 비롯한 주행에 필요한 도로정보와 횡단보도, 학교 앞 표시, 버스전용차로 표시, 버스정류장 표시 등 도로상황정보, 그리고 체육 및 놀이시설이나 보행로 등에 적용되는 탄성 포장재 및 건물 등의 내부 바닥재 또는 옥상의 방수용 바닥재로 적용되는 방수 포장재 등의 표면에는 자전거도로표시 등이 표시되어 있다.On the surface of concrete and asphalt pavement materials generally applied to pedestrians or roads, road information such as directional guidance symbols and speed limit signs, road information such as pedestrian crossings, school fronts, bus lanes, bus stops, etc. In addition, bicycle road markings are displayed on the surfaces of elastic pavements applied to physical education and play facilities or pedestrian paths, and internal pavements such as buildings, or waterproof pavements applied to rooftop waterproof plies.
이러한 노면표지는 도로교통법 제4조, 동법 시행규칙 제3조 2항 및 경찰청 교통노면표지 설치·관리 매뉴얼에서 규정하고 있는 각종 노면표지와 도로교통법 제11조2항의 규정에 의한 학교 앞 또는 유치원 앞(스쿨-존), 노인보호구역(실버-존), 청소년 보호법에 의한 청소년 통행금지구역(레드-존) 등의 노면표지 등을 포함한다.Such road markings in front of the school or kindergarten in accordance with the provisions of Article 4 of the Road Traffic Act, Article 3, Paragraph 2 of the Enforcement Regulations of the Act, and Traffic Road Sign Installation and Management Manual of the National Police Agency and Article 11, Paragraph 2 of the Road Traffic Act. Road markings such as (school-zone), elderly protection zones (silver zones), and juvenile protection zones (red zones).
이러한 노면표시 기호, 문자, 숫자 등의 노면표지는 도로를 이용하는 차량이나, 자전거, 보행자에게 안전운행이나 보행을 할 수 있는 정보를 주고 운행질서를 유지시켜주는 기능을 한다. The road signs such as road marking symbols, letters, and numbers provide information for safe driving or walking to vehicles, bicycles, and pedestrians using roads and maintain driving order.
특히, 이러한 노면표지는 눈 또는 비로 인하여 노면이 젖은 상태에서 차량의 야간 운행 시 차량의 헤드라이트로부터 발생된 불빛 반사로 운전자가 포장도로의 차선을 용이하게 식별할 수 있도록 함은 물론 교통사고의 위험과 교통 흐름의 방해를 최소화할 수 있도록 노면의 표면상에 표시되어야 한다.In particular, such a road sign is a light reflection from the headlights of the vehicle during night driving of the vehicle when the road surface is wet due to snow or rain, so that the driver can easily identify the lane on the pavement, as well as the risk of a traffic accident. It should be marked on the surface of the road surface to minimize interference with traffic flows.
이러한 노면표지를 설치하기 위한 종래의 방식으로는 일반 페인트를 이용한 상온형 도료나 융착식 도로표지용 도료를 사용하여 현장에서 시공기를 조작하여 표시하거나, 접착시트를 이용하여 설치하는 방법이 주로 사용되고 있다.As a conventional method for installing such a road sign, a method of operating a construction machine using a room temperature type paint or a fusion-type road sign paint using a general paint or an installation using an adhesive sheet is mainly used. .
한편, 도료에 의한 현장도색에 비하여 공사시간이 짧고 다양한 모양과 색상의 표현이 비교적 자유로운 접착시트의 경우에는 노면의 공극을 처리하지 못함으로 인하여 수분의 침투와 먼지, 습기 등으로 인한 박리현상을 극복하기 어렵고, 커팅 후의 자재손실 등의 여러 가지 결함이 있다.On the other hand, in the case of the adhesive sheet, which has shorter construction time and relatively free expression of various shapes and colors compared to the site painting by paint, it cannot overcome the pores of the road surface, thereby overcoming the peeling phenomenon due to moisture penetration, dust, and moisture. It is difficult to do so, and there are various defects such as material loss after cutting.
또한, 종래의 시공방법들은 퇴색 및 마모 주기가 짧아서, 자주 도로를 통제하면서 반복되는 시공 작업으로 날로 폭증하는 교통체증을 초래하게 되는 문제점도 있다. 또한, 도로에 차선작업 시 사용되는 페인트의 대부분이 휘발성 유성페인트가 사용되기 때문에 시공 시의 휘발성 물질 및 시공 후 차량의 통행에 따라 마모되어 발생되는 물질이 환경오염을 유발하는 새로운 문제점으로 대두되고 있다.In addition, the conventional construction methods have a problem that the fading and wear cycles are short, causing traffic jams to explode with repeated construction work while frequently controlling the road. In addition, since most of the paint used for the lane work on the road uses volatile oil paint, volatile materials during construction and materials generated by wear of the vehicle after construction are emerging as a new problem causing environmental pollution. .
이들의 과제를 해결하기 위해서, 특허문헌 1에는 아스팔트를 발열가속기의 간접열을 통해 가열하여, 스탬프 가능한 상태로 만든 다음, 스탬프 가능한 상태로 가열된 아스팔트 표면에 소정 형상의 문양을 형성한 후, 상기 가열된 아스팔트 표면을 소성 변형시켜 무기질화시키고, 우레아를 주성분으로 하는 미끄럼방지 액상에 거울칩을 배합하여, 상기 소성 변형되어 무기질화된 아스팔트 표면에 도포하는 도로의 포장방법을 개시하고 있다.In order to solve these problems, Patent Literature 1 discloses that asphalt is heated through indirect heat of an exothermic accelerator to make it stampable, and then a pattern of a predetermined shape is formed on the asphalt surface heated in the stampable state. Disclosed is a road pavement method in which a heated asphalt surface is plastically deformed to mineralize, a mirror chip is incorporated into an anti-slip liquid containing urea as a main component, and applied to the plastically deformed and mineralized asphalt surface.
그러나, 상기 특허에서 사용된 우레아를 주성분으로 하는 미끄럼방지 액상조성물은 접착력이 우수한 장점은 있으나, 인체에 해로운 환경호르몬을 발생시키는 유해물질을 포함하고 있어 어린이 보호구역 등에 적용시 환경오염의 문제점이 야기되고 있다. However, the non-slip liquid composition mainly composed of urea used in the patent has the advantage of excellent adhesion, but it contains harmful substances that generate environmental hormones harmful to the human body, causing problems of environmental pollution when applied to children's protected areas. It is becoming.

이하, 본 발명을 좀 더 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
전술한 바와 같이, 본 발명에 따른 도로포장용 수용성 아크릴-에폭시 모르타르는 아크릴 수지와 에폭시 수지의 단점을 보완하고, 장점을 살렸다. 일반적으로, 수용성 아크릴 수지는 시멘트와 혼합성 및 접착력이 우수한 장점이 있는 반면, 백화현상과 코팅 등의 2차 공정이 요구된다. As described above, the water-soluble acrylic-epoxy mortar for road paving according to the present invention compensates for the disadvantages of the acrylic resin and the epoxy resin and takes advantage of the advantages. In general, the water-soluble acrylic resin has the advantage of excellent mixing and adhesion with the cement, while the second process such as bleaching and coating is required.
한편, 수용성 에폭시 수지는 백화현상이 일어나지 않으므로 2차 공정이 불필요하고 접착력 및 내수성이 우수한 장점이 있는 반면, 시멘트와의 혼합성이 떨어져 시멘트와 함께 사용하기 어려운 단점이 있다.On the other hand, the water-soluble epoxy resin does not cause the whitening phenomenon, the secondary process is unnecessary and has the advantage of excellent adhesive strength and water resistance, while being poor in mixing with the cement has a disadvantage that it is difficult to use with cement.
이에 본 발명에서는 수용성 아크릴 수지 60∼80중량% 및 수용성 에폭시 수지 20∼40중량%로 구성된 액상 수지 100중량부에 대하여 백시멘트 30∼50중량%, 석고 2∼8중량%, 규사 40∼60중량% 및 안료 1∼5중량%로 구성되는 분체 성분 35∼50중량부를 구성하여 상술한 문제를 해결하였다.Therefore, in the present invention, 30 to 50% by weight of cement, 2 to 8% by weight, 40 to 60% by weight of silica sand based on 100 parts by weight of the liquid resin composed of 60 to 80% by weight of water-soluble acrylic resin and 20 to 40% by weight of water-soluble epoxy resin. The problem mentioned above was solved by constructing 35-50 weight part of powder components which consist of% and 1-5 weight% of pigments.
본 발명에 있어서, 상기 백시멘트는 모르타르의 강도 및 내오염성을 위해 첨가되며, 분체 성분에 대하여 30∼50중량%로 혼합하는 것이 바람직하고, 30중량% 미만이면 도료의 강도 및 내오염성이 떨어지고, 50중량%를 초과하면 도료의 강도 및 내오염성은 우수하나, 크랙이 발생하여 강도를 악화시켜 물성이 떨어지는 단점이 있다.In the present invention, the white cement is added for the strength and stain resistance of the mortar, it is preferable to mix at 30 to 50% by weight relative to the powder component, less than 30% by weight of the paint is inferior in strength and stain resistance, If it exceeds 50% by weight, the strength and fouling resistance of the paint is excellent, but there is a disadvantage in that physical properties are degraded due to cracks deteriorate.
본 발명에 따르면, 상기 석고는 2∼8중량%가 혼합되는데, 이는 모르타르의 강도증진과 팽창을 목적으로 첨가되며, 2중량% 미만이면 팽창이 약해져 크랙이 발생하고, 8중량%를 초과하면 팽창에 의해 크랙이 발생하는 단점이 있다.According to the present invention, the gypsum is 2 to 8% by weight is mixed, which is added for the purpose of enhancing the strength and expansion of the mortar, if less than 2% by weight is weakened expansion occurs cracks, if it exceeds 8% by weight There is a disadvantage that the crack occurs by.
상기 분체 성분에 충진재로서 첨가되는 규사는 모르타르의 강도를 보강하기 위해 사용되는데, 분체 성분에 대하여 40∼60중량%로 혼합하는 것이 바람직하고, 40중량% 미만이면 강도가 떨어지고, 60중량%를 초과하면 강도가 약해지는 단점이 있다.The silica sand added as a filler to the powder component is used to reinforce the strength of the mortar, preferably mixed at 40 to 60% by weight relative to the powder component, and less than 40% by weight, the strength drops, and exceeds 60% by weight. If the strength is weakened.
그 밖에 기타 첨가제로 사용되는 안료는 산화티타늄과 같은 무기안료가 바람직하며, 1∼5중량%로 혼합하는 것이 바람직하나, 특별히 제한받는 것은 아니다.In addition, pigments used as other additives are preferably inorganic pigments such as titanium oxide, and are preferably mixed at 1 to 5% by weight, but are not particularly limited.
본 발명에 있어서, 상기 분체 성분은 수용성 아크릴 수지 및 수용성 에폭시 수지로 구성된 액상 수지 100중량부에 대하여 35∼50중량부를 사용한다. In the present invention, the powder component is used 35 to 50 parts by weight based on 100 parts by weight of a liquid resin composed of a water-soluble acrylic resin and a water-soluble epoxy resin.
이때, 상기 사용량이 35중량부 미만이면 강도가 약하고, 50중량부를 초과하면 실 크랙이 발생하는 단점 있다.At this time, if the amount is less than 35 parts by weight, the strength is weak, and if it exceeds 50 parts by weight, there is a disadvantage in that a crack occurs.
본 발명의 포장방법은 기존 아스팔트에 프린트(print)하는 공법으로, 가열기의 열을 통해서 기존 아스팔트 도로를 녹여 열기가 남아 있을 때 형틀(template)을 표면에 놓고 스탬프(stamp) 한 후 굳혀서, 유기질 성분의 아스콘을 화학적 성분은 변이되지 않으나 물리적 특성을 변화시켜 해당 표면을 소성 변형을 유도한다. 그리고, 소성변형(rutting)이 된 후 상술한 본 발명의 수용성 아크릴-에폭시 모르타르를 도포한다.The paving method of the present invention is a method of printing on an existing asphalt, and melts the existing asphalt road through the heat of the heater and when the heat remains, the template is placed on the surface and stamped and hardened, thereby forming an organic component. The chemical composition of the ascon does not change but induces plastic deformation of the surface by changing its physical properties. After the rutting, the water-soluble acrylic-epoxy mortar of the present invention is applied.
본 발명의 바람직한 일 실시 예에 따르면, 먼저, 고압세척기 및 기타 장비를 이용하여 포장하고자 하는 아스팔트 도로의 표면을 세척하고, 수분, 돌, 먼지, 기타 스탬프에 유해한 물질을 제거한다. According to a preferred embodiment of the present invention, first, the surface of the asphalt road to be paved by using a high pressure washer and other equipment to clean the surface, and removes harmful substances in moisture, stones, dust, and other stamps.
일반적으로 아스팔트 도로는 아스콘 표층, 아스콘 중간층, 아스콘 기층, 보조기층, 동상 방지층, 아스콘 차단층, 및 노상으로 이루어진다. 다음 단계에서, 예를 들어, 발열가속기의 간접 열(150℃ 이상)을 통하여 기존 아스팔트를 10분∼20분간 가열하여 스탬프가 가능한 상태로 만든다. Asphalt roads generally consist of ascon surface, ascon interlayers, ascon bases, auxiliary bases, frostbite prevention layers, ascon barrier layers, and roadbeds. In the next step, for example, the existing asphalt is heated for 10 to 20 minutes through indirect heat (150 ° C. or more) of the exothermic accelerator to make the stamp possible.
이때, 열 출력은 약 200,000 ㎉/hr 정도이며, 이에 의해 아스팔트 표면 온도는 간접 열에 의해 약 300℃ 정도에 이른다.At this time, the heat output is about 200,000 kW / hr, whereby the asphalt surface temperature reaches about 300 ° C. by indirect heat.
아스팔트가 가열된 직후, 형틀을 아스팔트 표층에 놓고, 롤러(roller)나 압축장비(진동기계)를 이용하여, 일정한 깊이로 문양을 스탬프하고, 굳혀서 아스콘 표층의 소성변형을 유도한다. Immediately after the asphalt is heated, the mold is placed on the asphalt surface, using a roller or a compression machine (vibration machine), stamping the pattern to a certain depth and hardening to induce plastic deformation of the asphalt concrete surface.
그리고, 상기 형틀을 제거한 다음, 소성 변형된 아스팔트 표층에 본 발명에 따른 수용성 아크릴-에폭시 모르타르를 통상의 두께 범위로 도포한다. Then, after removing the mold, the water-soluble acrylic-epoxy mortar according to the present invention is applied to the plastically deformed asphalt surface layer in the usual thickness range.
이때, 도포되는 수용성 아크릴-에폭시 모르타르는 전술한 바와 같이, 수용성 아크릴수지와 수용성 에폭시 수지를 주성분으로 하여 각 수지의 단점을 보완하고 장점을 살려 아스팔트에 접착력이 우수하면서 친환경적인 장점이 있다.At this time, the water-soluble acrylic-epoxy mortar to be applied, as described above, has a water-soluble acrylic resin and a water-soluble epoxy resin as a main component to complement the disadvantages of each resin and take advantage of the excellent adhesive strength to the asphalt while having an environmentally friendly advantage.
이후, 양생 과정을 거치면, 차량 통행이 가능하다. 필요에 따라, 타이머가 장착된 열기구를 이용하여 상기 모르타르를 2∼5분간 가열하면 빠르게 건조시킬 수 있다. After that, if the curing process, vehicle traffic is possible. If necessary, the mortar can be rapidly dried by heating the mortar for 2 to 5 minutes using a hot air balloon equipped with a timer.
이하 실시 예를 통하여 본 발명을 좀 더 구체적으로 살펴보지만, 하기 예에 본 발명의 범주가 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited to the following examples.

한편, 고압세척기 및 기타 장비를 이용하여 표면이 세척된 아스팔트 도로에 발열가속기를 이용하여 약 170℃에서 아스팔트를 약 15분간 가열하여 스탬프가 가능한 상태로 만든다. 이때, 열 출력은 약 200,000 ㎉/hr 정도이며, 이에 의해 아스팔트 표면 온도는 간접 열에 의해 약 300℃ 정도에 이른다.On the other hand, by using a high-pressure cleaner and other equipment to heat the asphalt surface for about 15 minutes at about 170 ℃ using a heating accelerator on the asphalt road surface is made stampable. At this time, the heat output is about 200,000 kW / hr, whereby the asphalt surface temperature reaches about 300 ° C. by indirect heat.
아스팔트가 가열된 직후, 두께 0.6㎝, 폭 1.3m, 길이 20m의 격자문양의 형틀을 아스팔트 표층에 놓고, 롤러를 이용하여, 일정한 깊이로 문양을 스탬프하고, 굳힌 다음, 상기 형틀을 제거하였다. 이렇게 소성 변형된 아스팔트 표층에 상기 수용성 아크릴-에폭시 모르타르를 약 2㎜의 두께로 에어 기구를 이용하여 도포한다. 그 다음, 타이머가 장착된 열기구를 이용하여 상기 모르타르를 약 3분간 가열하여 건조시켰다. 이렇게 건조된 모르타르는 보행이 가능하였다.Immediately after the asphalt was heated, a grid pattern of 0.6 cm in thickness, 1.3 m in width, and 20 m in length was placed on the asphalt surface layer, and the roller was stamped to a certain depth using a roller, and then hardened, and then the mold was removed. The water-soluble acrylic-epoxy mortar is applied to the plastically deformed asphalt surface layer with an air mechanism at a thickness of about 2 mm. The mortar was then dried by heating for about 3 minutes using a hot air balloon equipped with a timer. This dried mortar was able to walk.
본 발명에 따른 모르타르는 유해성분을 포함하고 있지 않아 어린이 보호구역, 버스 전용차로, 버스 정류장, 공원, 아파트 단지 내의 아스팔트 도로 등에 적용될 수 있다. The mortar according to the present invention does not contain harmful components and can be applied to child protection zones, bus lanes, bus stops, parks, asphalt roads in apartment complexes, and the like.
따라서, 아스팔트에 미적인 기능을 부과하여 미관이 수려한 아스팔트를 만들 고 아울러 시인성도 높여 사고예방 효과와 상쾌한 거리, 걷고 싶은 거리를 조성할 수 있다.Therefore, by imparting aesthetic function to the asphalt to create a beautiful asphalt, and also increase the visibility, it is possible to create an accident prevention effect, a refreshing street, the distance you want to walk.
