Problems solved by technology

[0004] However, at present, the processing of the above-mentioned reflective fabrics is usually processed by conventional methods such as coating or coating, especially for the processing of the reflective layer. If an opaque reflective layer is used, in order to make the colored glue below the reflective layer The color effect of the adhesive layer can be reflected. However, the aluminum or silver reflective layer is usually formed by vacuum coating, and the processing process is not easy to control. The luster effect of the color layer below the reflective layer is reflected
Such as a reflective film disclosed in Chinese patent (authorized announcement number: CN2694295Y), including a transparent resin layer, a specular reflective layer and glass beads embedded in it, its processing method is equivalent to making the formed reflective layer continuous by plating. Completely cover the surface of the glue layer, so it is difficult to reflect the color effect under the reflective layer
There is also a reflective layer coated on the surface of each glass bead, as the Chinese patent application (publication number: CN104062697A) specifically discloses that only a layer of reflective layer is plated on the surface of the glass bead by vacuum evaporation, but such process operation It is more difficult, it is difficult to coat the surface of each glass bead with a reflective layer, and at the same time, this will greatly increase the complexity of processing, which is not conducive to industrialization

Embodiment 1

[0034] First implant a number of glass beads 1 with a high refractive index on the surface of the thermoplastic PE film material, so that the glass beads 1 are distributed on the surface of the thermoplastic PE film material in an orderly or disorderly manner, by controlling the temperature between 100°C and 110°C To control its sedimentation depth, the glass microspheres 1 are partially embedded in the PE film material to form a glass microsphere layer, and the mosaic depth is 30% of the thickness of the glass microspheres 1. The surface of the bead 1 side is coated, and an opaque gray reflective layer 2 of aluminum material is formed on the surface, with a thickness of 150 angstroms. The color adhesive layer 3 is formed by coating the surface with common colored polyester material, and then the hot melt adhesive layer 5 is glued on the surface of the color adhesive layer 3; A white base layer is compounded between the adhesive layers 5; after cooling, the thermoplastic PE fi...

Embodiment 2

[0036] First implant a number of glass beads 1 with a high refractive index on the surface of the thermoplastic PE film material, so that the glass beads 1 are distributed on the surface of the thermoplastic PE film material in an orderly or disorderly manner, by controlling the temperature between 100°C and 110°C To control its sedimentation depth, the glass beads 1 are partially embedded in the PE film material to form a glass bead layer 1, and the inlay depth is 50% of the thickness of the glass beads 1, which is equivalent to exposing half of the glass beads 1 to the outside , then, carry out coating treatment on the surface of the above-mentioned implanted glass microsphere 1 side that is exposed to the outside, and form an opaque gray reflective layer 2 of one deck aluminum material on the surface, so that the thickness of the gray reflective layer 2 formed is 100 angstroms, such as by vacuum coating, and then on the surface of the gray reflective layer 2, a colored adhes...

Embodiment 3

[0038] The specific manufacturing method of the two-color thermal film of this embodiment is the same as that of Embodiment 2, the only difference is that the thickness of the formed gray reflective layer 2 is 200 angstroms, and this embodiment also includes the use of the same laser cutting treatment conditions to make the glass micro The gray reflective layer 2 below the beads 1 is also partially cut to form partial light transmission. The size of the light transmission area can be properly adjusted according to actual needs, so that the gray reflective layer 2 below the glass beads 1 can reflect light locally and partially Light transmission characteristics, showing a two-color effect of gray reflective color and colorful color effect at the bottom, to obtain a corresponding two-color thermal film.

Abstract

The invention relates to a manufacturing method of a double-color reflective thermal attachment film, and belongs to the technical field of processing of a reflective material. In order to solve the problems that the existing method is complex in processing and cannot realize multi-level reflection, the invention provides the manufacturing method of the double-color reflective thermal attachment film. The manufacturing method of the double-color reflective thermal attachment film comprises the following steps: implanting a plurality of glass microbeads into the surface of a thermoplastic PE film material, controlling the settlement depth to inlaid part of the glass microbeads in the PE film material to form a glass microbead layer, and forming a light-tight gray reflective layer on the surface in which the glass microbeads are implanted; adhering a colored adhesive layer to the surface of the gray reflective layer and adhering a hot melt adhesive layer to the surface of the colored adhesive layer; and after stripping the PE film material, performing laser cutting treatment on the gray reflective layer at the position without being inlaid with the glass microbeads to form local or all light transmission. According to the manufacturing method of the double-color reflective thermal attachment film, stripping can be avoided, the advantage of high adhesion fastness is achieved, theprocess is simple, and two-level double-color effect of the color of the gray reflective layer and the color of the colored adhesive layer can be realized.

Description

technical field [0001] The invention relates to a method for manufacturing a two-color reflective thermal film, and belongs to the technical field of reflective material processing. Background technique [0002] Reflective materials have special properties such as retroreflection and no need to provide energy by themselves. It is widely used in road, aerospace, navigation, night operation and clothing decoration. The manufacture of reflective cloth involves the manufacture and compounding process of various materials. These materials include optical reflective elements, base layers, surface layers, bonding layers and other auxiliary layers. At present, the most popular application in clothing-related industries is the reflective fabric with glass beads as reflective elements. [0003] However, the existing reflective fabrics, because the monotonous color of the reflective material itself is generally gray or silver gray, or the monotonous color layer is used but the refle...
