Problems solved by technology

[0004] Although the advantages of two-component marking paint are very obvious, most road operation departments are unacceptable in terms of the price of the current common two-component marking paint, especially for the construction and maintenance of expressways. The line coating can only be scraped to meet the thickness requirements of the line coating. The cost of such construction is equivalent to 3-5 times that of hot-melt marking lines. However, if it is applied by spraying, it is difficult to spread the glass on the surface. The microbeads are firmly bonded to the marking coating, which makes it difficult for the reflective type of the marking coating to meet the needs of high-speed driving safety

Abstract

The invention relates to a coating technical process, in particular to a thick-layer spraying type two-component marking coating and a preparation method thereof. The thick-layer spraying type two-component marking coating comprises a component A and a component B, and the mass ratio of the component A to the component B is 3-3.5: 1. The component A comprises the following raw materials in parts by mass: 18-22 parts of active acrylic resin, 14-20 parts of polycaprolactone polyol, 4-10 parts of modified nano calcium carbonate, 10-17 parts of modified quartz powder, 4-7 parts of titanium dioxide, 15-21 parts of heavy calcium carbonate, 12-15 parts of modified glass beads, 3-10 parts of calcium sulfate whiskers, 0.4-0.6 part of a dispersing agent, 0.2-0.3 part of a flatting agent and 0.2-0.3part of a defoaming agent; and the component B is hexamethylene diisocyanate. By comprehensively applying the nano calcium carbonate, the mineral fibers and the modified quartz sand, the invention provides the two-component marking coating of which the thickness can reach 0.8-1.5 mm under spraying construction, and the two-component marking coating can ensure that a marking coating reaches an ideal thickness, and has the performance characteristics of good toughness, wear resistance, weather resistance and high pavement adhesion.

Description

technical field [0001] The invention relates to paint technology, in particular to a spray-coated two-component marking paint which comprehensively uses nanometer powder, mineral fiber and modified glass microspheres and a preparation method thereof. Background technique [0002] Road markings play an important role in ensuring the safety and smoothness of highway traffic, and improving road appearance and appearance. Especially on mountainous roads, reflective markings at night are very important for road traffic. [0003] The two-component marking paint has received high attention in recent years, due to the good flexibility, adhesion, wear resistance and weather resistance of the two-component marking paint, especially the two-component marking paint rarely contains Volatile harmful substances, so the environmental protection is more prominent. Compared with hot-melt marking lines, two-component coating marking lines have better visibility at night, and can still ensure...
