Road marking coating suitable for heavy traffic highway and preparation method of road marking coating
The invention relates to a road marking coating suitable for a heavy traffic highway and a preparation method of the road marking coating. The coating comprises the following raw materials: modified petroleum resin, petroleum resin, EVA resin, polyamide resin, a filler, a pigment, a plasticizer, fibers, internally-mixed reflective glass beads and surface-scattered reflective glass beads, and a modifier of the modified petroleum resin comprises SBS and epoxy acrylate. SBS and epoxy acrylate are used as modifiers to graft and modify petroleum resin, SBS and epoxy acrylate branched chains on the petroleum resin penetrate through or are connected with SiO2 hollow microspheres through molecular thermal motion to form a firm three-dimensional network structure, on one hand, reflective glass microspheres can be locked, migration and precipitation under the action of external pressure can be reduced, and on the other hand, the wear resistance of the marking coating can be greatly improved, and the reduction of the reflective property caused by friction, precipitation, falling and the like is prevented. Meanwhile, the SiO2 hollow microspheres and the modified petroleum resin have the effect of synergistically improving the compressive strength of the coating.
一种适用于重型交通高速路的道路标线涂料及其制备方法，涂料包括如下原料：改性石油树脂、石油树脂、EVA树脂、聚酰胺树脂、填料、颜料、塑化剂、纤维、内混反光玻璃微珠、面撒反光玻璃微珠，所述改性石油树脂的改性剂包括SBS和环氧丙烯酸酯。本发明以SBS和环氧丙烯酸酯为改性剂对石油树脂进行接枝改性，石油树脂上的SBS和环氧丙烯酸酯支链通过分子热运动贯穿或连接起SiO2空心微球，形成一个牢固的三维网状结构，一方面可将反光玻璃微珠锁住，减少外界压力作用下的迁移、析出，另一方面可大大提高标线涂料的耐磨性，防止因摩擦、析出、脱落等造成的反光性的下降。同时还发现，这种SiO2空心微球与改性石油树脂具有协同提高涂料抗压强度的作用。
