Damage-resistant high-brightness reflective glass bead and preparation method thereof

Abstract

The invention aims to provide a breakage-resistant high-brightness reflective glass bead and a preparation method thereof, the breakage-resistant high-brightness reflective glass bead comprises a glass bead inner core unit, an outer wrapping glass bead unit and an anti-pollution wear-resistant protective layer from inside to outside in sequence, and the glass bead inner core unit is located in the center of the breakage-resistant high-brightness reflective glass bead; the outer side wall surface of the periphery of the glass bead kernel unit is coated with an outer coating glass bead unit, and the outer wall surface of the periphery of the outer coating glass bead unit is provided with an anti-pollution wear-resistant unit; the impact resistance, the friction resistance and the light reflecting performance of the reflective glass beads are improved, the externally-wrapped glass bead layer provides the high-brightness light reflecting performance, the anti-pollution and wear-resistant layer can reduce abrasion of external force to the externally-wrapped glass beads, meanwhile, the leakproofness of the structure is improved, and it is prevented that external pollution erosion influences the durability of the light reflecting brightness.

Description

Technical field: [0001] The invention relates to the field of reflective optical materials, and mainly relates to a glass bead, in particular to a damage-resistant high-brightness reflective glass bead and a preparation method thereof. Background technique: [0002] With the development of economy and society, the continuous increase of motor vehicles, the traffic signs and markings on highways, etc., are generally made of glass beads or glass micro beads as raw materials. It has been proved by a large number of practice that the road traffic markings formed by single glass beads or high-brightness reflective glass beads have poor impact resistance, poor friction resistance, long-lasting reflective brightness and environmental pollution resistance during use. On the one hand, there are certain defects, which lead to the rapid attenuation of the reflective brightness, resulting in the shortening of the effective distance of road reflection, which seriously affects the road sa...

AI Technical Summary

Problems solved by technology

However, it has deficiencies in reflective durability, environmental pollution resistance and wear resistance.

[0004] However, after the above-mentioned reflective glass bead products are used as road markings, there are firstly that the durability of retroreflective brightness is poor and insufficient, and its impact resistance, friction resistance, water resistance and environmental pollution resistance are relatively low. Poor, cannot better and effectively solve the shortcomings of the current all-weather road bead products, such as high initial brightness, but poor persistent reflective brightness, etc.
