차선은 도로에서 안전하고 원활한 소통을 위해 필수적인 것으로서, 주행방향이나 차로와 차로 등을 구분하기 위한 목적으로 이용된다.The lane is essential for safe and smooth communication on the road, and is used for the purpose of distinguishing the driving direction, the lane and the lane.
이러한 차선은 도로 표지용 도료로 이루어지는데, 도로 표면과의 부착성, 어두운 길에서 빛을 반사하게 하여 도로 표지를 선명하게 해주는 글라스 비드(Glass bead)와의 부착성, 도장 작업시 이로 인하여 이동체 및 보행자의 통행을 제한하는 시간이 짧아야 하므로 빠른 시간 내에 경화되는 속건형이어야 한다.These lanes are made of road marking paints, which are adhered to road surfaces, adherence to glass beads which reflect light on dark roads to make clear road markings, It is necessary to shorten the time for restricting the passage of water.
하지만, 지금까지 사용되고 있는 종래의 상온경화형 유성 도료(1종) 및 수용성 도료(2종)는 건조가 늦어 차량을 통행 시키는데 많은 시간이 소용되어 교통 체증을 유발할 수 있는 문제점이 있고, 또한 2액형 도료(5종)는 도료의 건조는 신속하게 이루어지는 장점이 있지만, 글라스 비드를 고착시키기 위한 부착성의 개선이 필요하며, 동절기 등의 계절 변화에 따른 작업 온도 하락에 의해 도료의 점도 상승에 의한 스프레이 작업성의 균일도 저하의 문제가 발생할 수 있다.However, conventional conventional room temperature curing type oil-based paints (1 kind) and water-soluble paints (2 kinds) have a problem in that the drying time is so long that a large amount of time is spent for passing the vehicle, (5 kinds) are advantageous in that the paint can be dried quickly, but it is necessary to improve the adhesiveness for fixing the glass beads, and it is necessary to improve the sprayability due to the increase of the viscosity of the paint due to the seasonal change in the season A problem of lowering the uniformity may occur.

In order to improve the adhesion and durability of paints, the acrylic beads are dissolved in a solvent such as methyl methacrylate (MMA) and methyl ethyl ketone A subject comprising a resin solution prepared by dissolving an acrylic monomer of a butylacrylate monomer (BAM); And a curing agent comprising benzoyl peroxide (BPO) prepared in a liquid phase; (Japanese Patent Application Laid-Open No. 10-1426172 (Apr. 31, 2014) discloses a two-pack coating composition for road marking, which is obtained by copolymerizing acrylic beads with methyl methacrylate (MMA) and butyl acrylate monomer A resin solution prepared by dissolving a monomer in an acrylic monomer of a butylacrylate monomer (BAM); A base agent comprising an epoxy-based highly reactive resin for significantly reducing the amount of tertiary amine and improving whiteness and yellowing resistance; And a curing agent comprising benzoyl peroxide (BPO) prepared in the form of a liquid.

상기 표면 개질화된 SCMS는 1중량부 미만이면 내마모성의 향상을 기대하기 어렵고, 10중량부를 초과하면 시인성을 저하시키기 때문에 1~10중량부로 제한하는 것이 바람직하다.When the surface-modified SCMS is less than 1 part by weight, it is difficult to improve the abrasion resistance. When the amount of the surface-modified SCMS is more than 10 parts by weight, the visibility is reduced.
상기 변성 에폭시 수지는 도로과의 접착력을 극대화하고, 신율을 조절하는 역할을 하는 것으로서, 스테아린산 변성 에폭시 수지인 것이 바람직하다.The modified epoxy resin is preferably a stearic acid-modified epoxy resin, which maximizes the adhesive strength to the road and controls the elongation.
이러한 스테아린산 변성 에폭시 수지는 1중량부 미만인 경우에는 신율 조절 역할을 수행하기 어렵고, 5중량부를 초과하는 경우에는 내마모성이 저하될 우려가 있기 때문에 1~5중량부로 제한하는 것이 바람직하다.When the amount of the stearic acid-modified epoxy resin is less than 1 part by weight, it is difficult to control the elongation. When the amount of the stearic acid-modified epoxy resin is more than 5 parts by weight, the abrasion resistance may be lowered.

이러한 왁스는 0.5중량부 미만인 경우에는 저장성 효과를 기대하기 어렵고, 1중량부를 초과하는 경우에는 주제와 경화제와의 접촉을 방해하여 물성 저하는 물론, 경화시간이 늘어나기 때문에 상술한 범위로 제한하는 것이 바람직하다.When the amount of the wax is less than 0.5 parts by weight, it is difficult to expect a shelf-life effect. When the amount of the wax is more than 1 part by weight, the contact between the subject and the curing agent is disturbed and the curing time is increased. desirable.
