[0002] Glass beads are a new type of material with a wide range of uses and special properties developed in recent years. This product has the advantages of light weight, low thermal conductivity, high strength, and good chemical stability. Glass beads are the most commonly used night reflective material in road marking paints for urban roads. The application of reflective glass beads in road markings is achieved through retroreflective technology: when driving at night, the lights of vehicles shine on the road markings, and the reflective glass beads contained in the paint produce a retroreflective effect on the car lights. The driver can see the markings clearly and judge the driving route, effectively avoiding traffic accidents.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1-4 As shown, the utility model provides a long-life high-aluminum glass bead, comprising: a bead core 1; a protective layer 2, which is arranged on the outside of the bead core 1; a colloid layer 3, which is arranged between the protective layer 2 and the bead core 1; a reflective glitter sheet 4, which is arranged inside the colloid layer 3; a reinforcing layer 5, which is arranged between the colloid layer 3 and the bead core 1; a hook-shaped protrusion 6, which is arranged at the bottom of the bead core 1; the protective layer 2 comprises a silicon PU elastic layer 201, which is arranged on the outside of the colloid layer 3, and the surface of the silicon PU elastic layer 201 is coated with a transparent varnish 202.

[0024] In this embodiment, the reinforcing layer 5 is used to make the glass bead body have good impact resistance, wear resistance and pressure resistance. By coating the glass bead with a silicon PU elastic layer 201, the impact absorption of the glass bead body is enhanced, thereby increasing the service life of the glass bead body. The transparent varnish 202 on the surface of the glass bead can protect the glass bead and make the surface of the glass bead smooth, thereby increasing the refracted light refracted into the glass bead. The hook-shaped protrusion 6 provided under the glass bead can be embedded in the marking line, so that the reflective glass bead is not easy to fall off the marking line, thereby increasing the service life of the marking line.

[0025] Among them, the reflective flash piece 4 is a reflective aluminum-plated piece, and the reflective flash piece 4 is integrated with the glass beads in the bead body. The reflective flash pieces 4 in different directions inside the bead body can reflect reflected light at different angles to form multiple light spots, making the bead body "glowing". The reflective glass beads will enter the bead body after refraction under the illumination of the light source, and will be reflected multiple times by the reflective flash piece in the bead body to form light spots, so that the reflective glass beads will emit bright light under the illumination of the street lamp, increase the visibility range at night, remind the driver of the edge of the road, avoid the driver from hitting the curb, and enable the driver to grasp the outline of the road.

[0026] like Figure 1 and Figure 2 As shown, specifically, an aluminum oxide layer 7 is provided between the reinforcing layer 5 and the bead core 1; the aluminum oxide layer 7 can increase the overall hardness and strength of the glass bead, and improve its wear resistance and corrosion resistance.

[0027] like Figure 2 and Figure 3 As shown, specifically, a plurality of reflective flash sheets 4 are provided, and the plurality of reflective flash sheets 4 are evenly scattered inside the colloidal layer 3. The reflective flash sheets 4 are reflective aluminum-plated sheets, and the surface of the reflective flash sheets 4 is coated with a soft light coating 8; the soft light coating 8 is a nano high diffuse reflection coating. When strong light shines into the bead body, the bead body will emit a bright light, which may make people dizzy, and may cause visual discomfort to the human eye, reduce people's road perception, make people's eyes quickly fatigued and vision decreased. Coating the nano high diffuse reflection coating 8 on the reflective flash sheet 4 can effectively solve the glare problem, that is, using the principle of nano high diffuse reflection: the surface of the nano high diffuse reflection coating is attached with numerous nano-scale small particles, which can evenly convert the point light source formed by the reflection point on the reflective flash sheet 4 into a surface light source, so that the light forms a good diffuse reflection, thereby achieving a uniform effect, so that there are still multiple reflections in the bead body, but the light emitted by the bead body will be more uniform, soft, and full, which makes the human eye comfortable and improves the quality and effect of the reflective glass bead lighting.

[0028] like Figure 1 and Figure 2 As shown, specifically, the reinforcing layer 5 is connected to the colloid layer 3 and the aluminum oxide layer 7 through the adhesive layer 9, and the adhesive layer 9 is polyurethane, polyacrylate or polystyrene; the adhesive layer 9 is an organic adhesive, which does not change the oleophilic and non-hydrophilic properties of the glass beads, and is used to bond the reinforcing layer 5 to the colloid layer 3 and the aluminum oxide layer 7 through the adhesive layer 9, thereby improving the tightness between them.

[0029] like Figure 1 and Figure 2 As shown, specifically, a plurality of hook-shaped protrusions 6 are provided, and all are arranged at the lower half of the bead core 1, and the reinforcement layer 5 is made of polymer.

[0030] Working principle: The staff makes the glass bead body have better impact resistance, wear resistance and pressure resistance through the reinforcement layer 5, and enhances the impact absorption of the glass bead body by coating the glass bead with the silicon PU elastic layer 201, thereby increasing the service life of the glass bead body. The transparent varnish 202 on the surface of the glass bead can protect the glass bead and make the surface of the glass bead smooth, thereby increasing the refracted light refracted into the glass bead. The hook-shaped protrusion 6 arranged under the glass bead can be embedded in the marking line, so that the reflective glass bead is not easy to fall off the marking line, thereby increasing the service life of the marking line.
