Problems solved by technology

[0007] figure 2 Shown is the reflective phenomenon of the poorly rounded reflective original in the marking line, which is determined by figure 2 It can be seen that the retro-reflective effect of light on poorly rounded reflective elements is poor, and a large part of the light cannot return to the driver's sight due to various reasons, but escapes away from the driver's direction and is lost.

Embodiment 1

[0023] All-weather high refraction reflective microcrystalline ceramic beads, including inner core and core reflective element, the core reflective element includes the following components: titanium dioxide, calcium oxide, zirconia, boron oxide, aluminum oxide and inorganic salt additives;

[0024] The preparation process of the core reflective element includes the following steps: step 1, mixing titanium dioxide, calcium oxide, zirconia, boron oxide, aluminum oxide and inorganic salt additives, grinding and high-speed dispersion in a nano sand mill to obtain an inorganic slurry Step 2, the inorganic slurry is granulated by spray drying, and the particle size of the dried particles reaches 200-250 mesh; Step 3, the dried particles are sintered into particles in a high-temperature oxygen-enriched environment; Step 4, the particles are cooled and collected , Obtain the core reflective element after sieving;

[0025] The preparation process of the all-weather high-refraction ref...

Embodiment 2

[0058] The difference from Example 1 is that in the core reflective element, by mass percentage, the content of titanium dioxide is 60%-85%, the content of calcium oxide is 1.5%-15%, and the content of zirconia is 5%-10%. , The content of boron oxide is 2%-15%, and the content of aluminum oxide is 1%-10%.

Abstract

The invention provides an all-weather high-refraction reflective micro-crystal ceramic bead. The all-weather high-refraction reflective micro-crystal ceramic bead comprises an inner core and a core reflective element, wherein the core reflective element comprises the following components: titanium dioxide, calcium oxide, zirconium oxide, boron oxide, aluminum oxide and inorganic salt additives. By improvement of the product components, the refractive index (ND value) of the micro-crystal ceramic bead can reach more than 2.2; when high refractive index is reached, the weather resistant function, the abrasion resistant function, the water resistant function and the alkali resistant function of products and the adhesive force of the products with paints are improved, so that the products have high hardness and high abrasion resistant performance, the condition that the products reach the all-weather reflective effect is ensured, and at the same time, the consistency of the service lives of the ceramic bead and graticules is ensured.

Description

technical field [0001] The invention relates to a pavement marking reflective paint, in particular to an all-weather high refraction reflective microcrystalline ceramic bead. Background technique [0002] According to relevant statistical data, road traffic accidents account for 61% of all kinds of casualties, and night traffic accidents account for 73% of all traffic accidents, among which the ratio of driving accidents in rainy nights is the largest. The main reason for frequent traffic accidents on rainy nights is that the road markings lose their reflective performance in rainy nights, and the markings are not clear and lose their guiding effect, making it easy for drivers to deviate from the direction or drive in parallel. At the same time, it is also very easy to mislead the sense of direction because the guide arrows cannot be seen clearly. In addition, the driver's vision is blurred and sleepy, and he is prone to fatigue driving and so on. For this reason, how to e...
