Problems solved by technology

[0003] Due to the rolling and friction of the wheels of driving vehicles for a long time, and the influence of climate, temperature, and day and night changes, the markings on the road are prone to large-scale shedding, fracture, and incomplete wear. The markings began to appear blurred and the reflective effect decreased, which brought great difficulties and potential safety hazards to safe driving

[0049] Preparation of marking paint

preparation example 1

[0051] Marking paint is prepared by the following methods:

[0052] a: At a temperature of 75°C, mix 280kg C5 petroleum resin, 80kg titanium dioxide, 18kg PE wax, 10kg EVA, 14kg dioctyl ester, 390kg premixed glass beads, 880kg heavy calcium powder (118 mesh heavy calcium powder 380kg, 323 Purpose heavy calcium powder 500kg) and 310kg quartz sand (40~70 mesh), dry for 45min; the roundness rate of the premixed glass beads is 60%;

[0053] b: First, at a speed of 280r / min, mix the dried C5 petroleum resin and titanium dioxide in step a evenly, and then mix it with PE wax, EVA, dioctyl ester, premixed glass beads, heavy calcium powder and quartz sand Mix and stir for 30 minutes to obtain marking paint.

preparation example 2

[0055] Marking paint is prepared by the following methods:

[0056] a: At a temperature of 77.5°C, mix 300kg C5 petroleum resin, 75kg titanium dioxide, 21kg PE wax, 8kg EVA, 16kg dioctyl ester, 370kg premixed glass beads, 910kg heavy calcium powder (120 mesh heavy calcium powder 400kg, 325 Purpose heavy calcium powder 510kg) and 300kg quartz sand (40~70 mesh), dry for 52.5min; the roundness rate of the premixed glass beads is 80%;

Abstract

This application relates to a high-efficiency retroreflective hot-melt road marking and its production method, including the following steps: S1: heating the marking paint to 180-220 °C, stirring evenly, and keeping it warm for 5-10 minutes; S2: maintaining the temperature at 180-200 ℃ temperature, at 0.3~0.35kg / m 2 Sprinkle glass beads on the surface of the marking paint; S3: maintain the temperature of 180~190°C, discharge the material, and obtain high-efficiency retroreflective hot-melt highway markings. The markings prepared by this application have a high retroreflection coefficient, And it has good reflectivity in rainy nights, and it also has high wear resistance, water resistance and alkali resistance, which can achieve a long-lasting reflective effect.

Description

technical field [0001] The present application relates to the technical field of road markings, in particular to a high-efficiency retroreflective hot-melt road marking and a manufacturing method thereof. Background technique [0002] Traffic markings refer to signs that convey traffic information such as guidance, restrictions, and warnings to traffic participants on the road surface with lines, arrows, text, facade marks, raised road signs, and contour marks. They are the most basic traffic safety facilities. , can effectively reduce traffic accidents and traffic jams. At present, the application of road markings in my country is basically hot-melt markings for grade two and above roads, and hot melt markings for roads below grade two. According to the national standard, the retroreflection coefficient of the marking line must meet the requirements, so as to achieve the purpose of increasing night driving safety. [0003] Due to the rolling and friction of the wheels of ...
