Problems solved by technology

[0006] Although the microprism structure formed by the above method and equipment has excellent hardness, scratch resistance, heat resistance, solvent resistance, and good product consistency, due to the relatively few types of photosensitive resins and special properties, the general price are very high; and the photosensitive resin will have certain solvent emissions during the coating and drying process. When UV light irradiates the photosensitive resin to cure it, it will also cause part of the monomers in the photosensitive resin to escape and be exposed to the air. In addition, af

Abstract

The invention relates to equipment for producing a reflection film with a microprism array structure by using a cylinder mould. As photosensitive resin is used as a microprism molding material in the prior art, the defects that the selection range is narrow, the production cost is high, the subsequent processability is low, the application range is narrow and the like exist. The equipment for producing the reflection film with the microprism array structure by using the cylinder mould comprises the cylinder mould, a hot melting resin coating device and a mould pressing device, wherein the cylinder mould is provided with an inner surface and an outer surface; the outer surface is provided with a sunk continuous microprism array structure; hot melting resin is coated to one side surface of a resin film by the hot melting resin coating device; the side surface of the resin film clings to the outer surface of the cylinder mould; and the gap of the sunk microprism array structure is filledwith the hot melting resin through mould pressing. As the hot melting resin molding microprism array structure is used in the equipment for producing the reflection film with the microprism array structure by using the cylinder mould, the subsequent processability of the manufactured reflection film is more excellent, and the application range is wider; a drying or ultraviolet (UV) solidifying device is not needed by the equipment, thereby, the processing cost is low, the production speed can be obviously increased, and the production process is more environmentally friendly.

Description

technical field [0001] The invention relates to a device for producing a reflective film, in particular to a device for producing a reflective film with a microprism array structure. Background technique [0002] Reflective materials with a microprism array structure are more and more widely used in various road traffic safety facilities, vehicle passive safety protection devices, signs and personal safety protection products due to their excellent retroreflective properties. [0003] The invention patent application with the publication date of October 21, 2009, the publication number CN101561523, and the name "Production method of reflective film with microprism array structure" discloses a production of reflective film using photosensitive resin to form microprisms. The production method includes the main steps of: coating a photosensitive resin on a resin film, drying, heating and molding, and then rapidly curing by UV light irradiation, so that the resin film coated wi...
