Description
Technical field
The present invention relates to a kind of moulding process of optical thin film, in particular to a kind of microprism reflecting film and its manufacturer
Method.
Background technique
Microprism reflecting film is a kind of reflectorized material with high glistening intensity and excellent ageing-resistant performance, is widely used in
The fields such as different kinds of roads road safety marker, traffic safety facilities and safety device of vehicle can play apparent safe police and be shown as
With.Microprism reflective membrane in the prior art is made of reflective bottom, prism layer and function surface layer, and prism layer and function surface layer
Same material can only be used, the performance deficiency of homogenous material will be retained in finished product.
In terms of manufacturing method:
One, by United States Patent (USP) 4601861 " method and dress for precision optics map grid embossed on resin layer or laminated film
Set ", on July 22nd, 1986 is open, discloses the method and dress of a kind of precision optics map grid embossed on transparent thermoplastic film
It sets, which uses closed embossed die strip, is warming up to die strip in bringing-up section and is enough to make thermoplastic film vitrified
Temperature replicates its optics map grid through pressing, the temperature for being enough to make thermoplastic film to harden then is cooled in cooling section, is shelled
From realizing the continuous production of microprism reflecting film in this approach.It has the disadvantage in that
1. during the embossed precision optics map grid of transparent thermoplastic film, closed embossed die strip is converted from bringing-up section
To cooling section, temperature is transformed into the temperature (about 80 DEG C) of hardening hereinafter, temperature from the glass transition temperature (about 240 DEG C) of thermoplastic film
Difference is too big, takes a long time, for certain mold strip length, production efficiency is seriously restricted.
2. closed embossed die strip is constantly recycled in the so big the temperature difference range of a heating section and a cooling section, by high/low temperature
It alternately impacts, necessarily seriously affects its service life.
3. transparent thermoplastic film is covered on closed embossed die strip, it is gradually warming up to glass transition temperature, through pressing
During replicating optics map grid, the gas of film release can not be thoroughly discharged, and there are remaining possibility, therefore replicate optical picture
There are the possibility of mass defect for lattice.
Two, a kind of microprism reflecting film of Chinese patent CN201110183700.5 and its continuous production manufacturing method.
It discloses the construction of microprism reflecting film: the film includes microprism forming resin layer and surface resin layer, wherein micro-
Prism forming resin layer with a thickness of 40~150 microns, surface resin layer is anti-with a thickness of 20~200 microns and the microprism
The bimodulus coextrusion head of light film, calendering formation, the cooling continuous production manufacturing method removed.It is using inside accurate reflective membrane
Structure, manufacturing method, controllability is strong, high yield rate, high production efficiency, convenient for promoting and applying.It has the disadvantage in that
1. bimodulus coextrusion head prism layer and surface layer process, by extrusion characteristics it is found that this method prism layer and surface layer used
Resin can not be replaced flexibly, such as need to change resin and need replacing equipment or dismantle cleaning equipment, be replaced and cleaned that process is tedious the period
It is long；Another reflective membrane has different colours, and surface layer assumes responsibility for color function, and extrusion molding switching color is also required to longer cycle.
2. calendering formation replicated architecture, microprismatic optical function is realised in that accurate replicating microstructured, and precision architecture is multiple
System needs two elements: within the accurate resin layer thickness ± 1.5um of a；B. enough surface hardnesses and elasticity are needed to pressure roller.
Due to entering die strip after squeezing out in the method, the film with micro-structure there is no mature online precise thickness control method, pressure
The characteristic that elasticity and hardness are needed to pressure roller can not be all provided simultaneously with using precision mirror surface steel rider or heatproof silica gel roller by prolonging.This two o'clock
It will lead to microstructure replication and there is the imperfect region in part, cause light-reflecting property uneven.
3. the formation of air layer uses the uncrosslinked compound rear spontaneous curing of coating and prism layer, known prism film in the method
Production process is coiled material, there is certain winding tension, and uncured resin can be acted in pressure immerses micro-structure then solidification,
Cause micro-structure to deform, and then cause reflective membrane reflecting effect seriously lower, at the same bond or its adhesion strength of thermo-compression bonding compared with
Low, there are lamination problems in use.
