The polyurea road marked line spray coating composite coating material comprises a component A and a component B, wherein a formula of the component A comprises, by weight, 10-35 parts of a thermosetting resin, 10-35 parts of a thermoplastic resin, 20-70 parts of polyaspartic ester, 5-10 parts of a pigment filler, 0.15-0.3 part of a dispersing agent, 0.15-0.3 part of an additive, and the balance of a diluent agent, the number of the total parts is 100, a formula of the component B comprises, by weight, 80-90 parts of aliphatic polyisocyanate, and 10-20 parts of a diluent agent, the number of the total parts is 100, and the component A and the component B are mixed according to a volume ratio of 1-4:1 during use. The preparation method comprises: respectively preparing the component A and the component B, mixing the two components according to a certain ratio during use, and adopting a spraying coater to carry out spray coating.

Description

technical field [0001] The invention relates to a road marking paint for spraying construction and a preparation method thereof. Background technique [0002] Traditional solvent-based, hot-melt or water-based road marking coatings have poor adhesion to the road surface after construction, and are easy to fall off from the road surface, and the paint film is easy to stick to dust, mud, oil and other dirt, making the markings Lines become unclear, and the overall appearance effect is poor, affecting road traffic safety. In addition, the traditional road marking paint is made of thermoplastic resin, the formed paint film has low strength, poor wear resistance and short service life, and its affinity with reflective glass beads is poor, and the reflective glass beads sprinkled on the surface are easy to fall off; The resulting rough surface reduces the anti-fouling performance of the marking line. Especially for hot-melt marking paint, due to the need for heating construction...
