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 filled with 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
The present invention relates to a kind of equipment of producing reflective membrane, relate in particular to the equipment that a kind of production has the reflective membrane of microprism array structure.
Background technology
Reflectorized material with microprism array structure is owing to its remarkable reflex reflection performance, the fields such as different kinds of roads traffic safety facilities, vehicle passive security protective device, sign board and personal security's protective articles that are applied to more and more widely.
Open day is on October 21st, 2009; Publication number is CN101561523; The application for a patent for invention that name is called " working method with reflective membrane of microprism array structure " has disclosed a kind of working method of utilizing the reflective membrane of optical light sensitive adhesive moulding microprism; The key step that this working method comprises is: on resin film, apply photosensitive resin; Through dry; Heating and mould pressing; Solidify fast through the UV rayed again; Make the resin film that applied photosensitive resin and the microprism array structure mutual group on the photosensitive resin layer become laminated film; The final layer press mold is cooled, and this laminated film is the reflective membrane with microprism array structure.
Open day is on March 17th, 2010; Publication number is CN101672939; The patent of invention that name is called " production equipment with reflective membrane of microprism array structure " has disclosed and has adopted said method production to have the equipment of the reflective membrane of microprism array structure; Described production equipment comprises endless belt-shaped mould; The heating and mould pressing device; Cooling device; Coating unit; Drying device and UV solidification equipment; Endless belt-shaped mould has an inside surface and an outside surface; Its outside surface has the continuous precision microprism array structure that is convex shape, and coating unit applies optical light sensitive adhesive at a side surface of resin film; The resin film that has applied optical light sensitive adhesive carries out drying through described drying device; The outside surface of then a side surface that is coated with optical light sensitive adhesive on the resin film being close to endless belt-shaped mould through described heating and mould pressing device heat, mold pressing, make described optical light sensitive adhesive fill up the gap of protruding micro-prism structure; Under the situation of the microprism array structure tight engagement on the outside surface of optical light sensitive adhesive and endless belt-shaped mould; Utilize the UV solidification equipment to solidify optical light sensitive adhesive; And make its firm attachment on the resin film, form inseparable one with the resin film, applied the resin film of optical light sensitive adhesive, optical light sensitive adhesive and moulding micro-prism structure mutual group thereon after solidifying become laminated film; Described laminated film is handled through apparatus for supercooling, promptly forms the reflective membrane with microprism array structure.
The reflective membrane that makes through said method and equipment; Need through the coat of metal; Perhaps pass through supersonic welding connection technology or sweat soldering technology behind its microprism one side surface involution one hypoglyph; Pressure sensitive adhesive on the coat of metal or counterdie one side are compound more just can be made into the micro-prism type reflective membrane in fields such as being used for traffic safety sign or personal security's protective articles.And there are metallic reflector and the micro-prism type reflective membrane that a hypoglyph is arranged through involution that different ranges of application and field
