Method for preparing sealed reflective fabric material by using bead coating process

Abstract

The invention discloses a method for preparing a sealed reflective fabric material by using a bead coating process. According to the method, surfaces of glass beads are modified by a coupling agent; stable coupling agent coating layers are formed on the surfaces of the glass beads; the surfaces of the glass beads are relatively smooth; the other amino-terminated group of the coupling agent is a hydrophilic organic group; the compatibility between the coupling agent and the organic solvent can be improved; the interface bonding force between the glass beads and the coating can be improved; the film formed by the coating is high in compactness; the interface between the glass beads and the coating is relatively smooth, is similar to an ideal concave mirror, and has an effect of focusing the light; the light entering into the glass beads almost completely returns back along the original direction; the interface has an excellent retro-reflection effect and can achieve a safety warning effect.

Description

technical field [0001] The invention relates to a light-reflecting material, in particular to a method for preparing a closed-type reflective fabric material by using a bead-coating method. Background technique [0002] Retro-reflective materials can be simply called reflective materials. As a new type of material, reflective materials are mainly used in traffic signs. By adding reflective elements on the surface of the corresponding materials, the light can return in the same way to achieve the purpose of reflection; Under this condition, the reflective material achieves a visual effect hundreds of times more eye-catching than other non-reflective materials; and solid glass beads and prisms can be used as reflective elements of reflective materials. [0003] Factors such as the state of the glass bead-coating film interface and the nature of the interface will affect the retroreflective effect of the reflective material. For most of the existing reflective materials, the c...

Problems solved by technology

For most of the existing reflective materials, the compactness of the coating is poor after film formation or there are more air bubbles or other fillers in the coating film. The film interface becomes smaller. In this case, the light will not only scatter greatly, but also cause part of the light to escape through the glass bead-air interface. Whether it is scattering or light passing through the glass bead-air interface, it will Causes some light loss and weakens the retroreflection effect
