All-weather marking for rainy nights and preparation method thereof
The invention provides an all-weather marking for rainy nights and a preparation method thereof, belonging to the technical field of road markings. The all-weather marking for rainy nights comprises a hot melting coating layer, reflective beads for rainy nights and glass beads, wherein the reflective beads for rainy nights and the glass beads are dispersed on the surface of the hot melting coating layer; the refractive index of the glass beads is greater than or equal to 1.5; each reflective bead for rainy nights comprises a spherical inner core and a ceramic particle surface layer adhered to the surface of the spherical inner core, and the refractive index of each reflective bead for rainy nights is greater than or equal to 1.9; and the content of the reflective beads for rainy nights is larger than or equal to 300 g/m<2>, and the content of the glass beads is larger than or equal to 600 g/m<2>. According to the road marking, the reflective beads for rainy nights with the refractive index larger than or equal to 1.9 and the glass beads with the refractive index larger than or equal to 1.5 are arranged on the surface of the hot melting coating layer, and the content of the reflective beads for rainy nights and the content of the glass beads are controlled, so the optical retroreflection performance of the road marking in a rainy night environment can be effectively improved.
本发明提供了一种全天候雨夜标线及其制备方法，属于道路标线技术领域。本发明提供的全天候雨夜标线包括热熔涂料层、分散于所述热熔涂料层表面的雨夜反光珠和玻璃珠；所述玻璃珠的折射率≥1.5；所述雨夜反光珠包括球形内核和粘附于所述球形内核表面的陶瓷粒表层，所述雨夜反光珠的折射率≥1.9；所述雨夜反光珠的含量≥300g/m2，所述玻璃珠的含量≥600g/m2。本发明通过在热熔涂料层表面设置折射率≥1.9的雨夜反光珠、折射率≥1.5的玻璃珠，并控制雨夜反光珠与玻璃珠的含量，能够有效提高道路标线在雨夜环境下的光学逆反射性能。
