이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명에 의한 미끄럼 방지 기능을 갖는 도로 노면 표시 조성물은, MMA(Methyl Methacrylate) 수지, PMMA(Polymethyl Methacrylate) 수지 및 BA(Butyl Acrylate) 수지를 포함하는 혼합 수지 100중량부; 다관능성 아크릴 단량체 10~50중량부; 경화제 3~10중량부; 중합촉진제 3~10중량부; 규사 20~100중량부; 안료 5~10중량부; 알루미늄 옥사이드 10~20중량부; 및 세륨알루미늄 옥사이드 10~20중량부;를 포함하는 것을 특징으로 한다. The road marking composition having an anti-slip function according to the present invention includes 100 parts by weight of a mixed resin including a methyl methacrylate (MMA) resin, a polymethyl methacrylate (PMMA) resin, and a butyl acrylate (BA) resin; 10-50 parts by weight of polyfunctional acrylic monomer; 3 to 10 parts by weight of a curing agent; 3 to 10 parts by weight of a polymerization accelerator; 20-100 parts by weight of silica sand; 5 to 10 parts by weight of a pigment; 10 to 20 parts by weight of aluminum oxide; and 10 to 20 parts by weight of cerium aluminum oxide.
본 발명에 의한 도로 노면 표시 조성물의 주재료인 혼합 수지는, MMA(Methyl Methacrylate) 수지, PMMA(Polymethyl Methacrylate) 수지 및 BA(Butyl Acrylate) 수지를 포함한다.The mixed resin, which is a main material of the road marking composition according to the present invention, includes a methyl methacrylate (MMA) resin, a polymethyl methacrylate (PMMA) resin, and a butyl acrylate (BA) resin.
상기 메틸메타아크릴레이트(methylmethacrylate; MMA ; CH2=C(CH3)CO2CH3) 수지는, 아크릴산과 미타아크릴산 에스테르의 중합반응공정을 거쳐 이중 탄소결합을 갖도록 만든 반응형 수지로, 내구성, 내열성, 내화학성, 내마모성, UV 안전성 등 물성이 뛰어나고, 햇빛 등의 날씨 및 기후에 견디는 성질인 내후성이 우수하여 외부 환경 변화에 의한 부식 등을 억제함과 동시에 노면에 침투하여 일체화 시켜줌으로써 부착강도 및 인성을 개선하고, 안료 등에 의한 착색성을 좋게 한다. The methyl methacrylate (MMA; CH 2 =C(CH 3 )CO 2 CH 3 ) resin is a reactive resin made to have double carbon bonds through a polymerization reaction process of acrylic acid and mithaacrylic acid ester, durability, It has excellent physical properties such as heat resistance, chemical resistance, abrasion resistance, UV safety, etc., and excellent weather resistance, which is a property to withstand weather and climate such as sunlight, suppresses corrosion caused by external environmental changes, and at the same time penetrates into the road surface to improve adhesion strength and Toughness is improved, and colorability with a pigment or the like is improved.
본 발명에서는 점도가 10~1,000cps인 저점도 MMA 수지와 점도가 2,000~ 20,000cps인 고점도 MMA 수지를 1:0.5~1.5 중량비로 혼합하여 사용함이 바람직한데, 이러한 경우 그 물성이 더욱 우수하기 때문이다.In the present invention, it is preferable to use a mixture of a low-viscosity MMA resin having a viscosity of 10 to 1,000 cps and a high-viscosity MMA resin having a viscosity of 2,000 to 20,000 cps in a weight ratio of 1:0.5 to 1.5, and in this case, the physical properties are more excellent. .
또한, 상기 MMA 수지는 소량의 경화제만으로 경화 개시 후 1시간 이내에 완전히 경화가 완료되는 초속경성 수지이고, 통상 작업 가능시간은 20분 내외로서 작업성이 우수한 것은 물론, 강도가 매우 우수하다는 장점이 있다.In addition, the MMA resin is a super-fast curing resin that is completely cured within 1 hour after the start of curing with only a small amount of curing agent, and has the advantage of excellent workability as well as excellent strength as the normal workable time is about 20 minutes. .
다만, 이러한 MMA 수지는 단독 사용시 내균열성 및 휨추종성이 부족하다는 단점이 있는바, 본 발명은 이러한 단점을 폴리메틸메타크릴레이트(Polymethyl Methacrylate; PMMA) 수지 및 부틸아크릴레이트(Butyl Acrylate; BA) 수지를 함께 적용하여 개선하는 것이다.However, these MMA resins have disadvantages in that they lack crack resistance and bending followability when used alone, and the present invention overcomes these disadvantages with polymethyl methacrylate (PMMA) resin and butyl acrylate (Butyl Acrylate; BA). It is improved by applying resin together.
즉, 상기 PMMA 수지는 MMA 수지의 경화시 수축량을 감소시키고, BA 수지는 MMA 수지의 연성 및 탄성, 접착력 등을 개선하는 것이다. That is, the PMMA resin reduces the amount of shrinkage during curing of the MMA resin, and the BA resin improves ductility, elasticity, and adhesion of the MMA resin.
이때, 각 수지 간 배합비는 MMA 수지, PMMA 수지, BA 수지를 1:0.1~0.5:0.1~0.5 중량비로 혼합하여 사용하는 것이면 족한바, 이는 앞서 설명된 경화시 수축량, 연성, 탄성, 강도, 접착력 등을 고려한 것이다.At this time, the mixing ratio between each resin is sufficient as long as it is used by mixing the MMA resin, PMMA resin, and BA resin in a weight ratio of 1:0.1 to 0.5:0.1 to 0.5, which is the amount of shrinkage, ductility, elasticity, strength, and adhesion during curing as described above. etc. are taken into account.
이하, '중량부'는 상기 혼합 수지 100중량부를 기준으로 한다.Hereinafter, 'part by weight' is based on 100 parts by weight of the mixed resin.
또한, 상기 다관능성 아크릴 단량체는 분자 내에 공중합이 가능한 이중결합을 포함하여 가교제 역할을 수행하기 위한 것으로, 조성물의 경화시간을 단축하고 강도를 보강함과 동시에 각 재료 간의 결합력을 증대시켜 재료의 탈리를 방지하고, 기계적 강도를 높이는 것이다.In addition, the polyfunctional acrylic monomer contains a copolymerizable double bond in the molecule to serve as a crosslinking agent, and it shortens the curing time of the composition, reinforces strength, and at the same time increases the bonding force between each material to prevent material detachment. and to increase mechanical strength.
상기 다관능성 아크릴 단량체로는, 에틸렌글리콜 디메타크릴레이트(EDMA), 디에틸렌글리콜 디메타크릴레이트(2EDMA), 트리에틸렌글리콜 디메타크릴레이트(3EDMA), 테트라에틸렌글리콜 디메타크릴레이트(4EDMA), 트리메틸올 프로판 트리메타크릴레이트(TMPMA), 트리메틸올 프로판 트리아크릴레이트(TMPTA), 1,6-헥산디올 디메타크릴레이트, 폴리부틸렌글리콜 디메타크릴레이트 및 네오펜틸글리콜 디메타크릴레이트 중 1종 또는 2종 이상을 사용할 수 있다As the polyfunctional acrylic monomer, ethylene glycol dimethacrylate (EDMA), diethylene glycol dimethacrylate (2EDMA), triethylene glycol dimethacrylate (3EDMA), tetraethylene glycol dimethacrylate (4EDMA) , trimethylol propane trimethacrylate (TMPMA), trimethylol propane triacrylate (TMPTA), 1,6-hexanediol dimethacrylate, polybutylene glycol dimethacrylate and neopentyl glycol dimethacrylate One type or two or more types can be used
그리고 상기 다관능성 아크릴 단량체는 조성물 내 10~50중량부로 포함됨이 바람직한데, 상기 다관능성 아크릴 단량체가 10중량부 미만이면 가교 효과가 미미하고, 50중량부를 초과하면 유동성이 떨어져 작업성이 좋지 못하기 때문이다.And the polyfunctional acrylic monomer is preferably included in 10 to 50 parts by weight in the composition. If the polyfunctional acrylic monomer is less than 10 parts by weight, the crosslinking effect is insignificant, and when it exceeds 50 parts by weight, the fluidity is poor and workability is not good. Because.
상기 경화제는 상기 혼합 수지의 경화를 개시하기 위한 것으로, 벤조일퍼옥사이드, 2-디에틸아미노에틸아민, N-부틸디에탄올아민, 2-디이소프로필아미노에틸아민, 3-디메틸아미노-1-프로필아민, 3-디에틸아미노프로필아민, 트리에탄올아민, 트리이소프로판올아민, 3-디부틸아미노프로필아민, 트리프로판올아민, 메틸아민, N,N-디메틸 에탄올아민, 사이클로헥실아민, 헥사메틸렌 디이소시아네이트(HDI), 톨루엔 디이소시아네이트(TDI), 이소포론 디이소시아네이트(IPDI), 4,4' 메틸렌 비스(사이클로 헥실 이소시아네이트) 중 1종 이상을 사용할 수 있으며, 이외 공지된 다양한 경화제를 사용할 수 있다. The curing agent is for initiating curing of the mixed resin, benzoyl peroxide, 2-diethylaminoethylamine, N-butyldiethanolamine, 2-diisopropylaminoethylamine, 3-dimethylamino-1-propyl Amine, 3-diethylaminopropylamine, triethanolamine, triisopropanolamine, 3-dibutylaminopropylamine, tripropanolamine, methylamine, N,N-dimethyl ethanolamine, cyclohexylamine, hexamethylene diisocyanate (HDI) ), toluene diisocyanate (TDI), isophorone diisocyanate (IPDI), and 4,4' methylene bis(cyclohexyl isocyanate) may be used, and various other known curing agents may be used.
상기 경화제는 조성물 내 3~10중량부로 포함됨이 바람직한데, 상기 경화제가 3중량부 미만이면 부분경화가 일어날 수 있으며, 10중량부를 초과하면 경화시간이 단축되어 시공성이 좋지 못한 문제가 있기 때문이다.The curing agent is preferably included in 3 to 10 parts by weight in the composition. If the curing agent is less than 3 parts by weight, partial curing may occur, and if it exceeds 10 parts by weight, the curing time is shortened, and this is because there is a problem in poor workability.
상기 중합촉진제는 MMA 수지의 연쇄 중합을 돕는 역할을 하는 것으로, DMA(dimethyl aniline)를 사용할 수 있다. The polymerization accelerator serves to help the chain polymerization of the MMA resin, and DMA (dimethyl aniline) may be used.
상기 중합촉진제는 조성물 내 3~10중량부로 포함됨이 바람직한데, 상기 중합촉진제의 사용량이 적으면 경화시간이 지연되고, 과량이 되면 저장성에 문제가 있기 때문이다.The polymerization accelerator is preferably included in an amount of 3 to 10 parts by weight in the composition, because if the amount of the polymerization accelerator is small, the curing time is delayed, and if it is excessive, there is a problem with storage.
상기 규사는 조성물 내 충진제의 역할은 물론, 미끄럼 저항성을 부여하는 것으로, 상기 규사로는 7호사와 8호사를 혼합하여 사용할 수 있다. 이때, 상기 7호사와 8호사의 혼합량을 제한하지는 않으며, 이외 다양한 크기의 규사를 적용할 수도 있음은 당연하다.The silica sand serves as a filler in the composition as well as imparts slip resistance, and as the silica sand, a mixture of No. 7 and No. 8 can be used. In this case, the mixing amount of No. 7 and No. 8 is not limited, and it is natural that silica sand of various sizes may be applied.
상기 규사는 조성물 내 20~100중량부로 포함됨이 바람직한데, 그 사용량이 20중량부 미만이면 그 역할이 미미하고, 100중량부를 초과하면 접착력이 저하되는 등의 문제가 있기 때문이다.The silica sand is preferably included in an amount of 20 to 100 parts by weight in the composition. If the amount used is less than 20 parts by weight, the role is insignificant, and when it exceeds 100 parts by weight, there is a problem such as a decrease in adhesive strength.
상기 안료는 도로 노면 표시 조성물을 백색, 황색, 청색 등 원하는 색상으로 구현할 수 있도록 하여, 다양한 디자인 및 색상의 표면이 가능토록 하는 것이다. 상기 안료는 당업자에게 공지된 것이라면 어느 것이든 제한 없이 사용할 수 있는바, 백색안료로서는 이산화티탄, 산화아연 또는 황화아연 등을, 황색안료로서는 티탄옐로우, 크롬산아연, 황화카드뮴 또는 황산화철 등을, 그리고 청색안료로서는 감청, 군청 또는 프탈로시아닌 블루 등을 사용할 수 있다.The pigment enables the road marking composition to be implemented in a desired color, such as white, yellow, or blue, so that a surface of various designs and colors is possible. Any of the pigments known to those skilled in the art can be used without limitation, as the white pigment is titanium dioxide, zinc oxide or zinc sulfide, and the yellow pigment is titanium yellow, zinc chromate, cadmium sulfide or iron sulfate, and the like; As a blue pigment, royal blue, ultramarine blue, phthalocyanine blue, etc. can be used.
상기 안료는 조성물 내 5~10중량부로 포함됨이 바람직한데, 그 함량이 너무 적으면 색상의 표현이 어렵고, 과량이 되면 물성이 저하될 수 있기 때문이다.The pigment is preferably included in an amount of 5 to 10 parts by weight in the composition, because if the content is too small, it is difficult to express the color, and if it is excessive, physical properties may be deteriorated.
상기 알루미늄 옥사이드(Al2O3)는 미끄럼 저항성을 위한 것으로, 규사에 비해 마모량이 20배 이상 낮아 유지 관리가 용이하고, 마찰력도 뛰어나다는 장점이 있다. 이때, 상기 알루미늄 옥사이드의 입도가 너무 크면 도막으로부터 입자가 이탈될 확률이 있으므로, 그 입도가 1~100㎛인 것이 바람직하다The aluminum oxide (Al 2 O 3 ) is for slip resistance, and has the advantage of being easy to maintain and excellent in frictional force because the amount of wear is 20 times lower than that of silica sand. At this time, if the particle size of the aluminum oxide is too large, there is a possibility that the particles are separated from the coating film, so it is preferable that the particle size is 1 to 100 μm.
상기 알루미늄 옥사이드는 조성물 내 10~20중량부로 포함됨이 바람직한데, 그 배합비가 10중량부 미만이면 미끄럼 저항성이 좋지 못하고, 과량이 되면 전체적인 물성이 좋지 못해지기 때문이다.The aluminum oxide is preferably included in an amount of 10 to 20 parts by weight in the composition, because when the mixing ratio is less than 10 parts by weight, the sliding resistance is not good, and when the amount is excessive, the overall physical properties are not good.
