Retro-reflective structure body and preparation method thereof

Abstract

The invention relates to a retro-reflective structure body and a preparation method thereof. The retro-reflective structure body is a spherical body. The retro-reflective structure body comprises a silica core with the purity more than or equal to 95 percent, a reflective layer coated on the surface of the core and at least two glass beads bonded on the surface of the reflective layer, wherein the reflective layer comprises a reflective material and a bonder, and the mass of the reflective material accounts for 30 to 50 percent of the mass of the bonder. The retro-reflective structure body has underwater reflective function and can overcome the defect specular reflection of a water surface and realize retro-reflection under the condition of humidification and soaking in water. The retro-reflective structure body has a rugged surface with high anti-sliding value; and the rough surface can increase the anti-sliding value of the surface and the contact area between a reflective structurebody and standard line paint or a construction bonder to increase the bonding force between the reflective structure body and the standard line paint or a construction decorative surface, so the reflective structure body is not easy to fall.

Description

technical field [0001] The invention relates to a retroreflective structure and a manufacturing method thereof, in particular to a retroreflective structure and a manufacturing method thereof applied in the fields of road markings, building decorations, nameplates and the like. Background technique [0002] Glass beads are fine solid or hollow spherical glass particles with smooth surface, high hardness and good mechanical properties. They are made of silicate materials and have excellent chemical stability. In recent years, with the development of my country's economic construction, the demand for glass beads used in road markings, architectural decorations, nameplates and other fields as reflective elements is increasing day by day. Existing glass microspheres generally only have the ability to reflect light in a dry state. Under the conditions of humidity and rainwater immersion, the light reflection ability is very poor, and the retroreflection coefficient is zero; Diff...

Problems solved by technology

Existing glass microspheres generally only have the ability to reflect light in a dry state. Under the conditions of humidity and rainwater immersion, the light reflection ability is very poor, and the retroreflection coefficient is zero; Difference

In addition, because the existing glass microspheres are generally relatively smooth, not only the anti-skid value is very low, but also the combination with the adhesive is poor, and it is easy to wear off during use.
