Description
Technical field
The present invention relates to a kind of production equipment of reflective membrane, relate in particular to a kind of production equipment with 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, sign board and vehicle passive security protective device that are applied to more and more widely.So-called microprism array structure is meant by three structures that plane perpendicular to each other constituted each other, can carry out total internal reflection to the incident light from front surface, thereby improves reflection of incident light efficient greatly.Plane based on this structure is not limited to certain specific dimensions or shape, also is not subject to the optical axis direction of prism unit, claims this structure to be " cube pyramid ", " pyrometric cone " or " trihedral " usually.
According to the difference of micro-prism type reflecting material application, the forming method of its mould is divided into filing substantially and floats the method at quarter continuously.By the mould of filing gained, specification is less and thick, and the size of microprism is bigger, only is suitable for injection mo(u)lding and duplicates, and the reflectorized material of Sheng Chaning can only be applicable to fields such as vehicle passive security protective device and road profile sign thus.
In order to bring into play the advantage of the micro-prism type reflective membrane that is used for the traffic safety identification purposes, and can adopt the fexible film form, this just need reduce the size of corner unit greatly; In addition, in order to realize function with its light source of light reflected back, also must keep three reflective surfaces of corner type reflective membrane bright and clean, level and smooth, and vertical missing each other should be within a few minutes, as exceed this limit, or reflective surface is bright and clean, smoothness is not high, all will cause significant light scatter, thereby makes the light intensity decreasing that ad-hoc location obtains.Thereby for many years, people attempt adopting floating carving method to make the corner reflective membrane always.
U.S. Patent number 4601861, in open day on July 22nd, 1986, the patent of invention that the name of innovation and creation is called " being used at floating method and the device thereof of carving the precision optics map grid on tree resin layer or the laminated film " discloses a kind of on the film surface that the transparent thermoplastic material makes or carve the method and the device thereof of continuous corner type reflecting unit map grid in the laminated film come-up that described material is made.The instrument at quarter that floats continuously of metal strip form is adopted in this invention, and its outside surface has floating needle drawing lattice; Described instrument along closed path successively by heating station and cooling stations, in heating station, floating the corresponding site of instrument at quarter and the temperature of map grid rises to more than the film glass attitude transition temperature, be softened and its surface formation and the corresponding to pattern of floating needle drawing lattice up to film, and in cooling stations, the temperature that floating quarter, instrument was heated the position is reduced to below the described glass transition temperature, is cooled off fast through the floating material of carving moulding, thereby makes film hardening; Then film is peeled off from instrument.Described method and apparatus can carry out continued operation, has simplified technology in the past greatly, but also has many deficiencies:
1, described film need be heated in heating station on the glass temperature in the microprism forming process, its preference temperature is 425-475 °F, it is 218-246 ℃, in cooling stations, be cooled under the glass temperature again, promptly need be cooled to 180 °F, be equivalent to below 82 ℃, the temperature difference of heating and cooling is bigger, and film has bigger specific heat, therefore the time of its heating and cooling is longer relatively, for the endless belt-shaped mould of certain-length, this must influence its speed of production, in this patent of invention disclosed laminated film be with 0.8-1.2 rice/minute speed by floating engraving device, cause the reduction of its work efficiency.
2, in the heating and cooling process of above-mentioned long period, shaped article can produce deformation, and then causes consistency of product relatively poor.
3,, be the hardness, scratch resistance of the formed microprism of thermoplasticity resin of linear structure, heat-resisting and solvent resistance must be restricted, thereby also restricted the following process and the usability of product because the film that adopts is the thermoplasticity material.
