Description
Technical field
The utility model relates to a kind of equipment of producing reflective membrane, relates 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 be that October 21, publication number in 2009 are that the application for a patent for invention that CN101561523, name are 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 be that March 17, publication number in 2010 are that patent of invention that CN101672939, name are called " production equipment with reflective membrane of microprism array structure " has disclosed and adopts said method production to have the equipment of the reflective membrane of microprism array structure; Described production equipment comprises endless belt-shaped mould, 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 on it after solidifying become laminated film; Described laminated film is handled through apparatus for supercooling, promptly forms the reflective membrane with microprism array structure.
