Problems solved by technology
In the production process of this mold, the process is complicated, the equipment investment is large, and the mold processing efficiency is low
When microprisms are formed, the ring mold needs to be tensioned and rotated between the heating roller and the cooling roller. Frequent cooling and heating changes and tension lead to deformation of the mold and shorten the practical life of the mold.
A pair of molds have a short service life, and the pressing area is only 20,000 square meters, so they need to be replaced, resulting in high costs

Embodiment Construction
[0019] see figure 1 , The invention discloses a device and process for producing a microprism reflective film based on UV light curing of a microprism single-roll mold.
[0020] The equipment mainly consists of a frame (not shown in the figure), a discharge rack 1, a glue dispensing device 2, a front pressure roller 3, a microprism mold roller 4, a rear pressure roller 5, an ultraviolet curing machine 6, and a glue baffle 7 , receiving rack 8 etc. composition.
[0021] Among them, during the production process, since the microprism mold is fixed on the steel rod, it will not be deformed, and its pressing area can reach 100,000 square meters. Moreover, the manufacturing process of the microprism mold roller is simple, the manufacturing period is short, and the investment in equipment is low. Composed of single roll forming equipment, compared with other equipment, it saves a tension roll, heating and cooling facilities, and the equipment structure is simple. UV glue coating ...

Abstract
The invention relates to a reflective material, in particular to a microprism mold roller based preparation method of a UV light-cured reflective film. The preparation method comprises the steps of 1,placing a rolled film in a discharge rack, wherein the thickness of the film is 36-200 microns, and the width of the film is 1,300 mm, and unwinding the rolled film at the speed of 1.5-4.5 m / min; 2,laminating the film sequentially through a front pressing roller and a microprism mold roller coated with UV glue; and 3, curing the bonded film by using an ultraviolet curing machine to enable the UVglue to be attached to the film and form an angular cube cone, peeling the film at a back pressure roller, and winding the film into the microprism film. According to the preparation method, the costis low, and the service life of the mold is long.
Description
technical field [0001] The invention relates to reflective materials, in particular to a method for preparing a UV light-cured reflective film. Background technique [0002] Microprism reflective film is a retroreflective film with cube pyramid as the unit structure. It has excellent characteristics such as high retroreflection coefficient, simple manufacturing process, and convenient pasting. It is widely used in the field of traffic safety. In the microprism reflective film, the cube pyramid is the retroreflective unit, which plays the role of retroreflection. At present, there are two production processes in the market: one is the film hot-melt pressing forming process, and the other is the film coating light-curing adhesive forming process. Films include PMMA, PC, PVC, PET or a combination of any two of the above materials. [0003] The use of combined films is to meet different requirements in products or processes and to take advantage of different resins. The combi...
