Problems solved by technology

The most important process in the production of glass bead type reflective film is the bead planting link. The traditional process mostly uses the method of directly contacting the bead planting surface with the static glass beads, which is easy to cause uneven distribution of glass beads and cannot be arranged closely. Layers of microbeads overlap, which seriously wastes raw materials and affects the reflective brightness. In addition, cold lamination is generally used, and the sinking depth of glass microbeads is not easy to grasp

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the drawings and embodiments.

[0015] Such as figure 1 As shown, the glass microbeads 1 preheated to 80~90℃ in the oven are put into the fluidized bead tank 2, separated by a gas-permeable plate in the middle. The plates are distributed with uniform pores, and the pore size is smaller than the diameter of the smallest glass bead. . An electrostatic device is used to make the roll of the film take a positive charge, and the glass beads 1 have a negative charge. Hot air at 80° C. is blown from the bottom of the fluidized bead tank 2 to make the glass microbeads adhere to the surface of the adhesive layer 5. After the hot composite steel roller 3 and the rubber roller 4 are pressed together, the hot pressing temperature of the hot composite steel roller 3 is 60~70℃, and the air pressure is controlled at 0.3~0.35MPa, so that the glass beads 1 are evenly and tightly distributed on the surface of the adhe...

Abstract

A process for planting glass micro ball on single layer coplane of reflection film includes preheating glass micro ball in dry oven then placing them in fluidized ball tank to have film roller attached with positive charge and glass micro ball attached with negative charge, blowing hot air into fluidized ball tank to let glass micro ball bind on surface of adhesive using hot steel roller and rubber roller to press film and glass micro ball to let glass micro ball distribute on surface of adhesive uniformly and compactly.

Description

Technical field [0001] The invention relates to a reflective film manufacturing process, in particular to a reflective film glass microbead single-layer coplanar bead planting process. Background technique [0002] Reflective films can be divided into two categories: glass bead type and micro prism according to their different retroreflection principles. The most important process in the production of glass bead reflective film is the bead planting process. The traditional process usually uses the method of directly contacting the planted bead surface with the stationary glass beads, which easily causes uneven distribution of the glass beads and cannot be closely arranged. The microbeads overlap layer by layer, which seriously wastes raw materials and affects the brightness of reflection. In addition, cold composite is generally used, and the depth of the glass beads is not easy to grasp. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, t...
