S3: the laggard material bin of poly methyl methacrylate plastic particle dedusting；
S4: poly methyl methacrylate plastic particle is extruded into material strip from die head after extruder melting conveying；
S5: carrying out forming processes to the material strip of extrusion, make material strip between the first forming roller and the second forming roller roll compacting around
Cross, then roll compacting bypasses between the second forming roller and third forming roller, wherein the temperature of the first forming roller 90 ° -110 ° it
Between, the temperature of the second forming roller is between 100 ° -120 °, and the temperature of third forming roller is between 95 ° -115 °；First forming roller
Super mirror roller is used at fashioned iron with third, the second forming roller uses V-CUT structure roller, and second forms each of roller surface V
The height of type protrusion is 5 μm, and the distance at the tip of adjacent inverted V type protrusion is 50 μm；
S6: cooling down plate after molding, and is transferred to testing agency by deflector roll and is detected；
S7: coating processing is carried out to the plate after detection；
S8: cutting plate coated with film, obtains the surface micro-structure light guide plate of specified size；
S9: plate is cleaned, is packed.
Poly methyl methacrylate plastic particle is dusted processing before entering extruder.
Testing agency includes calibrator and defect inspection machine, and calibrator carries out thickness measuring, defect inspection to plate after molding
Machine check to the defect of plate after molding and alarm.
Compared with the prior art, the invention has the beneficial effects that: the second forming roller is changed to V- from super mirror roller
CUT structure roller, the structure after change can carry out micro-structure transcription to its surface in plate forming, improve the refraction of plate surface
Rate reaches the increased purpose of luminance, and luminance promotes 3-5%, moreover it is possible to production caused by preventing because of raw sheet material brilliant white point
The bad screening rate of plate is improved 3-5%, effectively improves product quality by the unqualified phenomenon of quality.
