Antistatic treatment technology of glass beads for reflective film

Abstract

The invention discloses an antistatic treatment technology of glass beads for a reflective film. According to the antistatic treatment technology disclosed by the invention, the Zeta potential on the surfaces of the glass beads which are treated by using an anionic surfactant is increased, and the surfaces have positive charges and have different charges with TiO2.nH2O, so that cladding of titanium dioxide on the glass beads can be effectively promoted, charges loaded on hollow glass beads are basically and completely neutralized, so that the glass beads have good antistatic property, a single glass bead layer which is uniformly distributed can be easily formed, and the reflective property and the quality of the reflective film prepared by the glass beads are obviously increased; meanwhile, due to the introduction of the titanium dioxide, the mechanical performance and the weather resistance of the reflective film can be effectively increased, the antifouling ability of the reflective film can be increased, and negative effects caused by dust, oil stains and the like can be prevented from being brought for the use of the reflective film.

Description

technical field [0001] The invention relates to a material of reflective glass microspheres, in particular to an antistatic treatment process of glass microspheres for reflective film. 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. [0003] The main raw materials used in reflective materials include resins, pigments, glass beads, etc., and any raw material is very important to the performance of reflective products. Among them, the bonding resin must have good construction performance and excellent bonding ability. For glass beads, it is required to h...

Problems solved by technology

[0004] At present, the transfer method is widely used in the production process of reflective film, and the first process is to plant beads. Due to the high surface energy and surface charge of glass beads, their dispersion is poor, which is not conducive to the formation of a single layer of dense and uniform distribution. The glass bead layer is easy to cause the glass beads to agglomerate and overlap, which will affect the performance of the reflective film and thus affect the product quality
