Abstract
Aiming at the defects in the prior art that the amount of planted glass beads is not easily controlled, the planted beads are not uniform, the process is complex and the like, the invention discloses a bead planting method of glass beads of reflective materials. The method comprises the following steps: a) putting the glass beads into a trough, and raising the temperature of a heating roller to 50-180 DEG C; b) heating a PET (Polyethylene Terephthalate) composite membrane through the heating roller; and c) uniformly scattering the glass beads in the trough through a feeding roller onto the surface of a sticky film layer of the heated PET composite membrane to obtain a PET composite membrane with uniformly-distributed glass beads. The method is simple in process and easy in operation. The temperature of the heating roller is set so that the glass beads can be more firmly stuck on the surface of the sticky film layer of the PET composite membrane. The glass beads on a planted-bead surface are tightly and uniformly arranged, the distribution density of the glass beads in a unit area can be regulated as required, and the use ratio of raw materials is increased.
