Definitions
- the invention relates to a process for the production of glass fiber reinforced thermoplastic sheets, their advantageous use and a device for carrying out this process
- thermoplastic melt a homogeneous thermoplastic melt in an extruder, which is pressed out between parallel running glass fiber mats via a nozzle. Subsequently, the glass fiber mats are impregnated with the thermoplastic melt under increased pressure and elevated temperature and the composite formed in this way is cooled under pressure.
- thermoplastic melt is only applied to one side of the glass fiber mats, so that subsequently, in order to ensure a uniform impregnation of the mat, high pressures at elevated temperatures have to be used during the pressing.
- high pressures it is necessary to use voluminous and therefore difficult to handle presses with high energy consumption.
- the object on which the invention is based is to provide an easy-to-carry out, energy-saving method for the production of glass fiber reinforced thermoplastic sheets, with which a uniform impregnation of the glass fiber mat (s) used can be achieved.
- a method of the type mentioned at the outset is therefore proposed, which is characterized in that at least one of the glass fiber mats (10, 11) passes through the nozzle gap (3 *, 4 ') of an impregnation nozzle (3, 4) is guided, which are fed by the extruders (1, 2) with the thermoplastic melt (26, 28) in a controllable manner, so that two melt streams (26', 26 "and 28 ', 28 ") are formed, which are applied to the top and bottom of the glass mats (10, 11) at the nozzle gap outlet (27, 27'), the glass fiber mat being pre-impregnated and subsequently impregnated with thermoplastic Glass fiber mats (30, 30 ') are guided into the inlet roll nip (18) of the double belt press (5) and precalibrated and then pressed under pressure by means of the cooling plates (22, 22') to the glass fiber mat-reinforced thermoplastic plates (25).
- the glass fiber mats (10, 11) are advantageously preheated in the nozzle gap (3 ', 4').
- thermoplastic melt (26, 28) is advantageously a low-viscosity polypropylene melt, which may contain additives such as peroxides.
- melt flow (26 ', 26 "and 28', 28") can be regulated by the melt slide valve (29, 29 ') attached in the distributor block (8, 9).
- the glass fiber mat advantageously consists of cut, tangled and / or unidirectional and / or directional uncut glass fibers with an area content of 450 to 1300 g / m 2 .
- the pre-impregnated glass fiber mats 30, 30 ' are pre-calibrated in the inlet roll nip 18 which is adjustable in its cross section. Then the thermoplastic-glass fiber mat composite formed in the pressure zone with max. 2 bar pressed.
- the device for carrying out the method according to the invention consists of the extruders (1, 2), the control units (8, 9) for controlling the thermoplastic melt flow (26, 28), the impregnation nozzles (3, 4,), each of which has two nozzle slots (31, 31 'and 32, 32'), the nozzle gaps (3 ', 4') for feeding the glass fiber mats being arranged between each two nozzle slots, and the double belt press (5) also being arranged in the cooling zone Cooling plates (22, 22 ').
- the device according to the invention is further characterized in that the nozzle gaps (3 ', 4') are designed such that they are conical towards the nozzle gap outlet (27, 27 '), the cross section of the nozzle gap at the nozzle gap inlet (3 1 , 4') ) is wider than at the nozzle gap exit (27, 27 ').
- the cooling plates (22, 22 ') advantageously serve at the same time as pressing plates, wherein they are provided on one side with the sliding foils (23, 23') on the contact surface with the steel strips (16, 17).
- control units (8, 9) advantageously have the melt slides (29, 29 ') for regulating the thermoplastic melt flow (26, 28).
- the device advantageously has guide belts (35, 35 ') in the double belt press (5), which are carried along endlessly at the sides and correspond in thickness to the preliminary bond (36).
- the device according to the invention is also characterized in that the cross section of the inlet roller gap (18), which is formed by the heated inlet rollers (12, 13), is adjustable.
- FIG. 2 shows the detail from FIG. 1 relating to the extruder units 1 and 2, the control units 8 and 9 with the melt slides 29, 29 ', and the impregnation nozzles 3, 4.
- FIG. 3 shows the detail according to FIG. 1 regarding the impregnating nozzles 3, 4 and the inlet roller rollers 12, 13 of the double belt press.
- the method according to the invention is carried out as follows.
- a thermoplastic for example polypropylene, which is optionally mixed with additives such as peroxides, is fed into the extruders 1, 2.
- the thermoplastic is melted in the extruders 1, 2 heated to at least the melting temperature of the thermoplastic and fed to the control units 8 and 9 in the form of the thermoplastic melts 26 and 28.
- the melt flow can be regulated by the measure of a melt slide 29, 29 '; the melt streams 26 ', 26 "and 28', 28" are formed, which are fed to the nozzle slots 31, 31 'of the impregnation nozzle 3 and 32 and 32' of the impregnation nozzle 4.
- the impregnation nozzles 3, 4 are heated at least to the melting temperature of the thermoplastic.
- the glass fiber mats 10, 11 are fed to the impregnation nozzles 3, 4 from the supply rolls 33, 34.
- These glass fiber mats can for example be needled random fiber mats with a surface area of 450 to 1300 g / m 2 .
- These glass fiber mats 10, 11 are fed in such a way that they pass through the preheated nozzle gaps 3 ', 4'.
- the nozzle gaps 3 ', 4'- are designed such that they are tapered towards the nozzle gap outlet 27, 27'.
- the nozzle gap cross section is therefore 3 ", 4" wider at the nozzle gap inlet than at the nozzle gap outlet 27, 27 ".
- the glass fiber mats pre-impregnated on both sides are then guided into the inlet roller nip 18 of the double belt press 5. This consists of the heated inlet roller pair 12,
- a glass fiber mat thermoplastic pre-composite 36 is formed by the contact pressure of the rollers 12, 13. This is fed to the cooling plates 22, 22 ', through which the heat is removed from the preliminary assembly 36.
- the bores 24, 24 'made in the cooling plates and through which the cooling medium, for example water, are arranged so that the flow directions of the opposing plates 24 on the one hand and 24' on the other are opposite. This ensures that the residual stresses in the thermoplastic, which usually arise during extrusion, are reduced.
- the cooling plates 22, 22 ' serve as pressure plates and are therefore provided with the slide films 23, 23' on the side facing the endless steel strips 16, 17; they are attached to the frame of the double belt press 5 by means of pressure cylinders 21, 21 'and are therefore pressed onto the pre-assembly 36 on both sides.
- the guide belts 35, 35 ' which are approximately the same as the thickness of the pre-assembly 36, are endlessly carried laterally in the double belt press 5 on both sides of the pre-assembly 36.
- the heat dissipation from the thermoplastic is brought about by the measure of the cooling plates 22, 22 ', so that the method according to the invention can be carried out in an energy-saving manner.
- the contact pressure of the cooling plates can be kept low, for example at 1 bar, in order to bring about sufficient pressing to the finished glass fiber reinforced thermoplastic plates 25. This is due to the fact that the sufficient pre-impregnation already at the nozzle gap outlet 27, 27 'of the impregnation nozzles 3, 4 takes place so that the contact pressure is not used for impregnation, but for the formation of the thermoplastic pre-composite or the finished plate 25.
- the cooled thermoplastic sheets 25 are fed to an arrangement of circular knives 6 after passing through the outlet roller pair 14, 15, on the side edges of which they are cut. Then the plates 25 are cut to length in a manner known per se by the guillotine shears 7.
- the glass fiber-reinforced thermoplastic sheets produced according to the method can have a thickness between 1 and 5 mm; their glass content is between 20 and 50%.
- a third glass mat can be guided in the gap 37 between the two impregnating nozzles 3 and 4 in order to increase the proportion of glass fibers.
- the glass fiber reinforced thermoplastic sheets produced by the process according to the invention can be used for the production of molded parts such as automotive parts by means of extrusion and / or compression molding processes.
- the glass mat-reinforced thermoplastic sheets are heated to their melting temperature, placed in a press mold and pressed under pressure to form a molded part.
