Manufacturing method of high-strength type reflection film

Abstract

The invention relates to a manufacturing method of a high-strength type reflection film. The manufacturing method of the high-strength type reflection film includes the following steps: step a, a bonding layer is coated on the surface of a first vase material; step b, a bead establishing layer is formed on the surface of a second base material with pressure-sensitive adhesive, and a reflection layer is plated on the surface of the outer side of glass beads of the bead establishing layer; step c, a light reflecting layer formed by the bonding layer, the reflection layer and the glass beads is formed; step d, embossing is carried out on the back face of the bonding layer through a hot-press embossing roller, and therefore partial of the bonding layer is pressed to form square protruded ribs, and transparent surface material is connected with tops of the protruded ribs; step e, after the bonding layer is embossed, a supporting layer is sprayed on the back of the bonding layer so as to form a plane; and step f, the pressure-sensitive adhesive is evenly coated on the back of the supporting layer, and release materials are covered on the pressure-sensitive adhesive. According to the manufacturing method of the high-strength type reflection film, the smooth supporting layer can be acquired, coating of the pressure-sensitive adhesive can be smooth and uniform, bonding effect is good, and sizing material can be saved.

Description

technical field [0001] The invention relates to a manufacturing technology of a reflective material, in particular to a manufacturing method of a high-strength grade reflective film. Background technique [0002] Reflective film is usually used to attach to the surface of buildings, transportation facilities, vehicles and other objects, and has the purpose of marking and warning. In order to improve the reflective intensity level of the reflective film, the high-strength reflective film usually adopts a multi-layer composite structure, which includes a surface layer, a reflective layer and a pressure-sensitive adhesive layer, which is pasted on the surface of buildings, vehicles, etc. through pressure-sensitive adhesives. Creates a reflective surface. In the existing structure, the reflective layer is usually composed of an adhesive layer, a support layer, glass beads and a reflective film. Its manufacturing method is usually to first form an adhesive layer, compound a sup...

AI Technical Summary

Problems solved by technology

In this structure, there is a concave pattern on the back of the support layer after embossing. When the pressure-sensitive adhesive is applied again, the pressure-sensitive adhesive is thicker in the depression of the pattern and thinner in other places, so the pressure-sensitive adhesive layer is uneven and affects the product. Adhesive performance

When the pressure-sensitive adhesive layer is thin, it will affect the bonding. If the adhesive force is not enough, it will cause foaming and wrinkles.
