Description
Technical field
The present invention relates to a kind of polymer-extruded micro-embossing forming method, be mainly used in the polymer matrix film surface pressure and make microstructure graph, application mainly contains: the fields such as making of polymer grating, polymer light conducting plate, polymer base radiator, micro polymer Mechatronic Systems, polymeric micro-fluidic chip, surface-mounted integrated circuit.
Background technology
Polymer hot padding moulding is a kind of emerging graph copying technology, it is compared with traditional photoetching technique has following characteristics: equipment is simple, easy to operate, operation succinct (technological parameter is less), the accuracy of repetition height of fine structure, mould that processing charges is low, more expensive only need be processed once, can realize advantages such as duplicating in enormous quantities of same microstructure, owing to the demand to microstructural articles increases gradually, its development speed is also more and more faster in recent years.
The basic principle of this technology is: at first polymer matrix film is heated to its more than vitrification point 30 ℃～100 ℃ (for crystal polymer thing substrate, temperature will reach more than the melt temperature), then under certain pressure effect, impressing mould (needed microstructure graph is arranged on it) is pressed on the polymer matrix film, polymer is filled in the micro-structural on the mould, the demoulding behind the cooling and shaping reaches the purpose that graph copying shifts.
Mostly the forming method that is used for micro-embossing at present is to adopt flat hot stamp machine, nano marking press described in patent 200510019944.4, its principle all is that the polymer matrix film under the room temperature is fixed on the lower plate of hot stamp machine, and heating-cooling device and positioner are housed on the lower plate.Impressing mould is fixed on the upper plate, and heating-cooling device also is installed on it.During work, at first the polymer matrix film that is fixed on the lower plate is heated, make it reach the needed temperature of impression.Mould also will be heated to certain temperature, and is can mold filling complete to guarantee polymer.Upper substrate drive mould pressurizes to polymer matrix film then, and polymer is filled in the impressing mould, after pressurize cooling a period of time, carries out the demoulding.Thereby finish the time processing process.This method belongs to discontinuous formula production, infrabasal plate heating cooling is too frequent and speed is slow, and energy consumption is big, and the flowability of the polymer matrix film after the post bake is difficult to reach desired degree, often cause the graph copying low precision, micro-structural shifts imperfect.In addition, when upper substrate was exerted pressure, owing to adopt direct press type, the pressurization area was big, and upper substrate is easy to unbalance stress, causes the upper substrate buckling deformation to cause the polymer matrix film discontinuity, not only impressed area and was restricted, also influence impression Products Quality.
For this reason, invented a variety of mode of heatings and be used for improving the slow-footed problem of heating cooling, as employed electromagnetic wave heating in the patent 200410050075.7 etc., the heating cooling effectiveness when these methods have improved hot padding has been saved molding time.Patent 02131969.3 and patent 200510069953.4 have been invented a kind of thermal marking method that pressurizes with gas, because the equal pressure distribution character of gas molecule, the homogeneity question of pressure distribution in the time of can solving hot padding makes the impression area unrestricted, the pressurization good uniformity.The production equipment of these methods more complicated all but, production efficiency is low, and the repeatable accuracy of product is poor.
In order to improve the above-mentioned shortcoming of dull and stereotyped thermal marking method, patent 200810068662.7, designed the continuous micro-embossing method of pulley type, basic principle is that two rollers that rotate synchronously of employing are finished the impression to polymer matrix film, one of them roller has the micro-embossing mould, polymer matrix film heats by impression roller, regulates the pressure that is applied on the polymer matrix film by regulating two distances between the roller.This structure can realize continous way production, owing to be the line contact, has reduced to impress the required power that applies when impressing simultaneously, and the Embosser distortion is little, has improved the uniformity of pressure distribution.But, when being applied to the polymer hot padding, this kind method require the efficiency of heating surface of roller very high, could guarantee that like this polymer matrix film can reach temperature required fast when continuous rolling.The while calcining temperature is high and the dwell time is short, and these all can cause the elastic recovery phenomenon occurring behind the polymer micro-structural shaping and demoulding, can't guarantee the precision of graph copying.In addition, owing in the roller heater will be installed, reduce the rigidity of roller like this when this method is applied to micro-embossing, increased the uneven possibility of pressure distribution.Patent 200620022753.3 has designed the structure of multiple roll, specialized designs preheat roll be used for heating, also have the pressurize chill roll simultaneously.But the number of roller is more, makes installation and positioning accuracy be difficult to guarantee, poor synchronization when organizing the roller operation, complex structure more; Simultaneous temperature also can't accurately be controlled, the bad adjusting of technological parameter.
Summary of the invention
Micro-embossing forming method among the present invention has been realized the connect use of micro-embossing machine with extruder, directly carries out micro-embossing after the polymer matrix film of extruding is flattened, simultaneously by the improvement of micro-embossing equipment being realized the serialization of production technology.
Existing invention all is to use the finished product polymer matrix film to carry out hot padding mostly, polymer matrix film under the room temperature is heated to when impression needed temperature needs a lot of energy, and the flowability of polymer matrix film is lower than the substrate good fluidity when extruder is extruded just after the post bake.In addition,, be easy to take place buckling deformation during the heating pressurization, influence impression quality if polymer matrix film is fixing bad during post bake.Among the present invention, we are the use of connecting with extruder of micro-embossing machine, directly carry out micro-embossing after the sheet material of extruding is flattened, and have so not only saved complicated heating and cooling system, have saved a large amount of heat energy, and the flowability of polymer matrix film is guaranteed.In order to realize above purpose, the present invention has mainly done following improvement to the micro-embossing method.
1. flatten and transfer thick device: polymer is relatively more responsive for process conditions such as temperature and pressures.Owing to be subjected to various condition effect, the thickness after polymer matrix film is extruded may be inhomogeneous, and this inhomogeneities shows that polymer matrix film extrudes direction and thickness direction, and we more are concerned about its inhomogeneities at thickness direction herein.Generally speaking, the thickness error after substrate is directly extruded is greatly between ± 100～200 microns, and this microstructure size that may will impress greater than us.So if carry out micro-embossing after polymer matrix film is directly extruded, roughly the substrate pressure distribution is inhomogeneous, thick place pressure is big, and thin place pressure is little, influence impression quality.Therefore, how to guarantee that the thickness before the polymer matrix film impression is evenly most important.
The uniformity of polymer matrix film thickness when guaranteeing micro-embossing, we are provided with one and flatten and transfer thick device after polymer matrix film is extruded, with this substrate of extruding is flattened, and guarantee that its thickness is even, can regulate the thickness of substrate simultaneously.Flatten and transfer thick device mainly to be made up of two pre-THICKNESS CONTROL rollers that flatten, its spacing can accurately be regulated according to different needs, and the spacing degree of regulation requires to reach in the 0.01mm.Simultaneously, on two cylinders the precise dose control device is installed all, be used to control roller temperature, two pre-THICKNESS CONTROL rollers that flatten can adopt anisothermal temperature control method, the roller temperature height that is used for micro-embossing to guarantee the good flowability of polymer, fully flattens its surface, the backing roll temperature is lower, so that polymer matrix film has cooling and shaping to a certain degree.But the temperature of two rollers all will be controlled at more than the polymer matrix film vitrification point, otherwise impression the time make polymer matrix film need just can be warmed up to for a long time temperature required, thereby influence the speed of micro-embossing.When substrate is very thin, also can adopt the isothermal control mode.Polymer matrix film is behind the pre-pressing THICKNESS CONTROL roller through two, and its thickness is guaranteed.Because polymer is relatively responsive to temperature, thus temperature control precision require to reach ± 1 ℃ in.
2. the installation of heating and heat-insulating device: because we directly carry out micro-embossing after polymer matrix film will being extruded pressing, and polymer matrix film is easy to cooling.Therefore, in order to guarantee that polymer sheet still remained on certain temperature before entering the micro-embossing machine, simultaneously also in order to control process conditions more accurately, we have installed a heating and heat-insulating device between cross-head and micro-embossing machine, be used to guarantee that polymer matrix film impresses needed different temperatures process conditions when treating the temperature of stamping surface and controlling different polymer to impress.
Because the size of the micro-structural of impression has only the hundreds of micron, even littler.Different with common impression, only need during micro-embossing will be to be impressed the heating of polymer matrix film surface get final product, and firing rate wants fast, temperature control precision is wanted height
In addition, heater need adopt contactless heating, and adopts the closed loop thermal control system that the temperature on polymer matrix film surface is accurately controlled, and temperature control precision is in ± 1 ℃ of scope.Mode of heating can have: modes such as infrared heating, ultraviolet heating, resistance heated, eddy-current heating, hot blast heating, can select according to different actual conditions.
3. three-roller type imprinting apparatus: it is to add a pressurize cooling roller that is used for the pressurize typing on the basis of two roller platens again, be installed in a side of impression roller, angle between it and the roller platen can be regulated, so that regulate different pressurize cool times according to different materials.Polymer matrix film has impressed and has entered into to advance between pressurize chill roll and the roller platen cold pressurize cooling after the micro-structural, to guarantee polymer matrix film cooling and shaping fully, the precision of assurance graph copying.It with impression roller between be connected with spring, to guarantee having certain pressure between the roller.Coat the soft coating of one deck rubber-like simultaneously on the roller surface, destroyed with the micro-structural that prevents to impress.After pressurize cooled off roller and remove, can also carry out the hot padding of the double-side micro structure of polymer matrix film.
Effect of the present invention: flatten and transfer thick device to guarantee polymer matrix film after extruding, carry out the micro-embossing uniformity of thickness before.After polymer matrix film is extruded, also keeping very high temperature, heater is easy to just to make its surface reach desired imprint temperature, has improved the efficiency of heating surface, makes speed of imprint can improve a lot.Simultaneously because the polymer matrix film flowability of just having extruded is more much better than post bake, so can mold filling complete.The installation of the cooling of pressurize simultaneously roller has guaranteed enough pressurize shaping times, has guaranteed the dimensional stability after the demoulding of impression goods.
