Description

Technical Field

[0001] The invention relates to the technical field of glass cat's eye road stud preparation, in particular to a glass cat's eye road stud and a preparation method thereof. Background Art

[0002] Road studs, also known as road studs, road signs, markings, reflective road studs, etc., are mainly used to distinguish lanes and provide warning functions, so that drivers can identify the scope, characteristics and direction of the road in a more comfortable situation. In the absence of road studs, the marking paint used to separate the roads will be covered with dust, dim lights or rain, and it will be difficult for drivers to distinguish the scope, characteristics and direction, which may cause confusion and fatigue, and even cause traffic accidents. Therefore, on higher-level roads, protruding road studs are usually installed to improve the driver's alertness, comfort and safety.

[0003] There are many types of road studs, which can be roughly divided into three categories: three-dimensional right-angle corner conic mirror retroreflection method, circular lens directional retroreflection method, and cat's eye lens omnidirectional retroreflection method. The materials of the reflective sheets and bases used are metal, ceramic, plastic and composite materials. Among them, the cat's eye lens omnidirectional retroreflective tempered glass road stud is composed of a glass body and a metal-coated reflective layer (coated around the disc and bottom surface of the lower half of the body). It has a 360-degree focusing and reflection effect, and can provide reflection functions in all directions. This is a unique feature that other road studs do not have. In addition, since the cat's eye road stud does not use plastic materials, it is only composed of a glass body and a metal-coated reflective layer, both of which are environmentally friendly materials, so it has environmental advantages. However, there are some challenges in the manufacturing process of traditional glass cat's eye road studs. For example, existing glass cat's eye road stud products have problems such as poor strength and reflectivity. Summary of the invention
