Extruder hopper, while matching part machine for diffusant rationing to single screw extrusion machine；
4th step, hot melt: by the raw material of completion third step mixing diffusant in single screw extrusion machine, using 220 DEG C~260 DEG C
Temperature is kneaded plasticizing and becomes solution；
5th step, extrusion calendaring molding: raw material is kneaded after plasticizing becomes solution and is delivered to multi-layer co-extruded mould by single screw extrusion machine
Head, full-automatic multi-layer co-extrusion hanger-style die squeeze out the uniform thin slice of multi-layered thickness to multi-rolling mill, and multi-rolling mill is being incited somebody to action
Composite wafer pressing is integral, obtains the optics plate with a thickness of 0.5mm~10mm；
6th step, cooling and detection: the plate after multi-rolling mill pressing is exported to slow cooling frame Slow cooling, is set to slow cooling frame
On flaw detecting instrument and thickness gauge real-time monitoring is carried out to plate quality and thickness and is fed back to signal full-automatic more
Product thickness is adjusted in layer co-extrusion clothes hanger die head；
7th step, temperature control and hot pressing: it is laggard to the permanent control of plate surface temperature that the permanent machine of temperature is equipped with nine pairs of temperature control rollers
Enter accurate temperature control hot press, micro- structure nickel plate of accurate temperature control hot press cylinder surface carries out micro- structure to product, and foundation produces before micro- structure
The different micro- structure in product surface is replaced；
8th step, cuts stacking: being delivered to trimming dragger excision both sides rim charge by traction laminating machine plate coated with film, then defeated
It send to transverse cutting unit and carries out crosscutting being finished product, finished product is grabbed stacking by manipulator.
13. online hot press composite board material production technology as claimed in claim 12, which is characterized in that optics plate surface texture
For one of pyramid, arc-shaped, cylindrical, prism shape, planar shaped and multi-layer co-extruded shape, described its structure of prism shape
For ∧ either ∩, 70~130 ° of its angle of prism shape, height is 5~55 μm；It is arc-shaped be 10 with cylindrical diameter~
220 μm, be highly 10~60 μm.
14. online hot press composite board material production technology as claimed in claim 13, is characterized in that, the plate is single layer base
Material or multi-layer co-extruded substrate.
15. online hot press composite board material production technology as claimed in claim 12, is characterized in that, the diffusant is inorganic
The spherical ultra tiny spherical particle of silicon or organosilicon.
