Description
본 발명은 융착식 도료 조성물에 관한 것으로 실란계 표면 개질제로 표면개질한 코디어라이트 입자를 이용하여 내마모도 및 내후성이 우수한 도료 조성물을 제공할 수 있다. The present invention relates to a fusion-bonded coating composition, and can provide a coating composition having excellent abrasion resistance and weather resistance by using cordierite particles surface-modified with a silane-based surface modifier.
교통 정보 전달과 교통사고를 방지 등 차량 운행의 안전과 소통을 위해 도로 상에는 다양한 종류의 노면 표시가 시공되어 있다. 일반적으로 노면 표지용 도료를 이용하여 노면에 중앙선, 방향 표시, 정지 표시, 속도 표시 등을 표시하는데 최근에는 수용성 노면 표지 도료 대신, 융착식 플라스틱 도료나 상온경화형 플라스틱 도료가 많이 사용되고 있다. Various types of road markings are installed on the roads for the safety and communication of vehicle operation, such as the transmission of traffic information and the prevention of traffic accidents. In general, road marking paints are used to display centerlines, direction signs, stop signs, speed signs, etc. on the road surface, but recently, instead of water-soluble road marking paints, fusion-type plastic paints or room temperature curing plastic paints have been widely used.
이 중에서, 융착식(thermoplastic) 노면 표지용 도료는 4종 도료로 그 종류를 구분하고 있고, 수지를 기반으로 여기에 각종 안료와 유리알 등을 포함시켜 도료의 융해를 통해 노면 표시를 시공한다. 융착식 노면 표지용 도료의 경우 열융해방식으로 시공하기 때문에 시공 시간이 짧고 재시공이 자유로운 장점이 있어 한국 등록특허 제2177185호 등과 같이 관련 기술 개발이 활발하다. 그러나 융착식 도료는 다른 도료에 비해 접착력이 상대적으로 떨어지고 계절 변화에 따른 온도 차에 민감하여 융착식 도료로 시공한 노면 표시는 수축 및 팽창에 의한 손상과 마모가 쉽게 일어나는 문제가 있다.Among these, thermoplastic road marking paints are classified into four types, and road markings are constructed by melting the paint by including various pigments and glass beads based on resin. In the case of fusion-type road marking paint, since it is constructed by the heat fusion method, it has the advantage of short construction time and free re-construction, so related technology development is active, such as Korean Patent No. 2177185. However, fusion-type paints have relatively low adhesion compared to other paints and are sensitive to temperature differences due to seasonal changes, so road markings constructed with fusion-type paints have a problem in that damage and wear due to contraction and expansion easily occur.
이에 융착식 도료가 가지는 장점을 살리면서 노면 표시를 위한 도막에 요구되는 내마모성을 확보하는 동시에, 부착력이 강하고 환경 변화에 따른 내구성 변화를 방지할 수 있는 융착식 도료 개발이 필요하다. Therefore, it is necessary to develop a fusion-type paint that can secure the abrasion resistance required for a coating film for road marking while taking advantage of the advantages of the fusion-type paint, and at the same time, have strong adhesion and prevent durability changes due to environmental changes.
본 발명은 융착식 도료 조성물에 관한 발명으로 실란계 표면 개질제로 표면개질한 코디어라이트를 포함하여 시공이 편리하고 물성이 우수한 융착식 도료 조성물을 제공할 수 있다.The present invention relates to a fusion-bonding coating composition, which includes cordierite surface-modified with a silane-based surface modifier, and can provide a fusion-bonding coating composition that is convenient in construction and has excellent physical properties.

The alkylsilane-based surface modifier can remarkably improve the compatibility between the cordierite particles and the hydrocarbon resin, and the vinylsilane-based surface modifier can improve the compatibility and adhesion to the road surface as well. According to one embodiment of the present invention, when both a vinylsilane-based surface modifier and an alkylsilene-based surface modifier are used for surface modification of cordierite particles, the vinylsilane-based surface modifier: alkylsilane-based surface modifier = 1: 3 to 1: 3 It can be mixed and used in a weight ratio of 5, and within this range, adhesion to the road surface can be secured and the compatibility of cordierite can be remarkably improved.
본 발명의 노면 표지용 융착식 조성물은 평균입경이 15 내지 30㎛, 바람직하게는 17 내지 28㎛인 탄산칼슘을 포함할 수 있다. 탄산칼슘 입자를 포함하여 코디어라이트 입자와의 관계에 의한 바이모달 효과를 나타냄과 동시에 노면 표지의 표면 경도를 확보하고 내구성이 뛰어난 노면 표시를 시공할 수 있다. 본 발명의 일 실시예에 따르면, 노면 표지용 융착식 조성물에서 탄산칼슘은 탄화수소 수지 100 중량부 대비 50 내지 80 중량부, 바람직하게는 55 내지 75 중량부 포함될 수 있다. 탄산칼슘을 소량 포함할 경우 표면경도 저하를 유발할 수 있고, 탄산칼슘을 다량 포함할 경우 내마모도의 저하가 발생할 수 있다. The fusion bonding composition for road marking of the present invention may include calcium carbonate having an average particle diameter of 15 to 30 μm, preferably 17 to 28 μm. Including calcium carbonate particles, it is possible to exhibit a bimodal effect due to the relationship with cordierite particles, secure the surface hardness of road markings, and construct road markings with excellent durability. According to one embodiment of the present invention, calcium carbonate in the fusion bonding composition for road marking may be included in an amount of 50 to 80 parts by weight, preferably 55 to 75 parts by weight, based on 100 parts by weight of the hydrocarbon resin.

According to one embodiment of the present invention, the average particle size ratio of cordierite particles to calcium carbonate particles in the fusion bonding composition for road marking is cordierite particles: calcium carbonate particles = 1:15 to 30, preferably 1:17 to 1:17. May be 27. By satisfying the average particle size ratio of the two particles, a more robust road sign can be formed by the bimodal effect. When the average particle diameter of calcium carbonate particles is smaller than the above range, there is a problem in that durability is not improved by the bimodal effect, and when the average particle diameter of calcium carbonate particles is large, calcium carbonate is separated from the road surface by continuous impact. This may cause a decrease in the durability of the label.
