Further, the thickness of the acrylic resin print layer is 100 to 150 μm. The acrylic resin printing layer is used as a substrate layer of the soft-paste signboard, and the thickness range is suitable for being internally provided with a radio frequency data chip and being in pressure connection with the glass bead layer on the premise of ensuring that the soft-paste signboard is as thin as possible.
Further, the particle size of the glass beads is 50-80 mu m, and the refractive index is 1.9-2.0. The diameter of the glass beads is one of the important factors influencing the light reflecting effect of the soft-paste signboard. When the diameter of the glass beads is smaller, the number of the glass beads in the unit area of the reflective printing layer is increased, the glass beads are easy to adhere or are in bead stacking and missing, so that uneven distribution of the glass beads is caused, the coverage rate of the glass beads is reduced, the luminous intensity of a single glass bead is low when the diameter of the glass beads is smaller, and the comprehensive result is low luminous intensity of emitted light, so that the reflection effect is poor; when the diameter of glass bead is great, the glass bead is evenly arranged at reflection of light printing layer, then glass bead coverage rate improves, reflection of light intensity reinforcing, and reflection effect is better.

The special viscoelasticity of the acrylic pressure-sensitive adhesive material is utilized to enable the colloid to generate viscous flow under the action of small force and form van der Waals force with an adherend, so that higher adhesive force is generated; meanwhile, as the adhesive active agent is in an oily state generally, when the adhesive active agent is matched with the pressure-sensitive adhesive, the pressure-sensitive adhesive is often coated thick, or the initial viscosity of the pressure-sensitive adhesive is improved, and the manufacturing cost is likely to be increased. And the property of the adhesive active agent can be changed by adding a certain amount of simethicone, so that the adhesive force of the pressure-sensitive adhesive is not damaged any more. Therefore, the use amount of the pressure-sensitive adhesive can be saved, and the pasting effect is improved.
