In recent years, on the surface of thermoplastic resin board, impose the heavy reflecting plate (plastics system reflecting plate) of microprism processing, can in reflecting plate field, casting field, building field etc., use.
As the heavy reflectivity plate of this class, the U.S. generally acknowledge the beaded glass type arranged with the cube edge type.Usually, beaded glass type good, the good brightness that causes at distinguishing at a distance with because of the light reflection of cube edge type at in-plant distinguishing.
In the heavy reflectivity plate of above-mentioned cube edge type is made, the floral designs that embossed pattern forms with model correctly must be duplicated on the thermoplastic resin board.
For this reason, particularly, thermoplastic resin board pressurize under suitable temperature and pressure, and importantly, this pressurized state should keep official hour facing to the model of embossed pattern formation usefulness.
In the past, as the manufacture method according to the heavy reflectivity plate of such necessary condition, what for example proposed has continuous pressurization (with reference to special public clear 60-56103 communique) and a driving-belt method (with reference to the public clear 5-17023 communique of spy).
Above-mentioned continuous extrausion process is for overlapping on driving-belt and the sheet material of the solid phase of supplying with continuously, and with a plurality of pressue devices with heating or cooling function, the model that embossed pattern is formed usefulness sequentially pushes pattern is duplicated manufacture method on the plate.
Above-mentioned driving-belt method is the roller with a pair of mutual cramping, will have the driving-belt of model and the thermoplastic resin board pressurization of embossed pattern, with this figure is duplicated method for making on the plate.
But if adopt above-mentioned continuous pressurization, speed of production is slow, and because device is complicated, so need to maximize.
If adopt above-mentioned driving-belt method, self has embossed pattern driving-belt, so as the permanance of the driving-belt of mould problem has taken place again.
On the other hand, as melt the tabular resin of extruding from the extruder die first melt, use the method for the heavy reflectivity plate of driving-belt manufacturing, do not constitute the manufacturing technology of heavy reflectivity plate self, can be with reference to using the spy to open flat 6-55613 communique, open flat 3-6919 communique in fact, open the plate manufacturing technology of middle records such as flat 1-83092 communique in fact.
But,,, think that the transparency of plate is not enough in the occasion of not adding nucleator opening about the spy in the technology of flat 6-55613 communique.Opening in the technology of flat 3-6919 communique about real, the occasion that forming speed is high, since short between the face nip, so think that the surface gloss of driving-belt one side is poor.Open in the relevant technology of flat 1-83092 communique in above-mentioned reality, use elastic body, but on driving-belt rubber-coated elastic body, therefore the problem of permanance is arranged.
The invention is characterized in, the employed manufacturing installation of manufacture method with thermoplastic resin board of embossed pattern is equipped with 1st roller of surface with the resilient material coating, and between the 1st and the 2nd roller, reel and adorning the metal non junction driving-belt that the surface is a minute surface, the 3rd roller that contacts with the 1st roller by above-mentioned metal non junction driving-belt, be designed to adjoin the form of above-mentioned metal non junction driving-belt, the surface of above-mentioned the 3rd roller is processed to the embossed pattern forming face, the method of using this manufacturing installation manufacturing to have the thermoplastic resin board of embossed pattern is, the above-mentioned thermoplastic resin board of molten condition is imported between the above-mentioned metal non junction driving-belt and above-mentioned the 3rd roller that contacts with above-mentioned the 1st roller, with the extruding force between the above-mentioned the 1st and the 3rd roller, one side makes above-mentioned resilient material elastic deformation, one side planarly contacts pressurization with the 3rd roller with above-mentioned thermoplastic resin board with the above-mentioned the 1st, and duplicate embossed pattern and cool off simultaneously, in this cooling period, when the resin of above-mentioned thermoplastic resin board is the occasion of non-crystalline resin, the surface temperature of above-mentioned the 3rd roller to be remained under dew point～(resin Tg+20) ℃, and the resin of working as above-mentioned thermoplastic resin board is the occasion of crystalline resin, the surface temperature of above-mentioned the 3rd roller will remain under dew point～(m.p.-30 of resin) ℃, then, with above-mentioned metal non junction driving-belt this thermoplastic resin board is pressurizeed and cooling facing to the 3rd roll surface shape ground contact.
The thermoplastic resin board of said above-mentioned molten condition for example, is the thermoplastic resin board after just having melt extruded from the die head of extruder, or with solid-state thermoplastic resin board heating and melting resin plate etc.
