Definitions
- the invention relates to a fine-grained polyarylene ether ketone (PAEK), its preparation by grinding of porous PAEK and its use.
- PAEK polyarylene ether ketone
- the grinding of polymers with different grinding units and grinding processes is an established technology that is already used for a wide variety of grinding products, for example, for polyesters, polyamides or polyolefins. These polymers are usually ground from the corresponding commercial granular form in a cryogenic milling process to the corresponding powders. Usually, pin mills or fluidized bed mills are used at operating temperatures of up to -60 ° C. PAEK and in particular polyetheretherketone (PEEK) are characterized among others by excellent tribological and mechanical properties; They are therefore very difficult and with great effort to a fine powder to be ground.
- PEEK polyetheretherketone
- Another method known from WO 99/50339 is to mix PAEK with another polymer and thereby determine the particle shape of the PAEK. After dissolving the other polymer in a suitable solvent, the powdered PAEK is exposed. This method is very expensive. On this basis, the object of the invention was to find a little complicated grinding process with improved Mahlausbeute for the production of fine-grained PAEK powder.
- This object has been achieved by a process in which a porous PAEK having a BET surface area of more than 1 m 2 / g, preferably of more than 4 m 2 / g, more preferably of more than 8 m 2 / g and particularly preferred of more than 12 m 2 / g is ground to a powder.
- the porous PAEK is usually prepared by reacting an aromatic dihalogen compound with a bisphenol and / or a halophenol in the presence of alkali or alkaline earth carbonate or bicarbonate in a high boiling aprotic solvent to a PAEK, discharging and solidifying the melt, optionally grinding, z , In a hammer mill, extracting the resulting particles with one or more organic solvents to remove the reaction solvent and with water to remove the inorganic salts, and then drying.
- the particles to be extracted may be prepared from the reaction mixture other than by milling, also by granulating an extruded strand, applying a drop to a chilled metal strip, prilling or spray-drying.
- the degree of porosity obtained after the extraction depends in particular on the content of reaction solvent in the material to be extracted. In this respect, it is advantageous to remove only a portion of the reaction solvent during spray drying. Otherwise, the way in which the particles to be extracted are produced is not critical.
- Method was prepared and is in a compact form, for. B. as granules are dissolved in a suitable high-boiling aprotic solvent, whereupon the hot solution, as described above for the melt obtained in the reaction, converted into particle form and extracted with one or more organic solvents.
- T represents a direct bond, an oxygen atom or two hydrogen atoms
- Z and Z ' are hydrogen or phenyl groups. This is preferably diphenylsulfone.
- the PAEK contains units of the formulas
- Ar and Ar ' represent a bivalent aromatic radical, preferably 1,4-phenylene, 4,4'-biphenylene and 1,4-, 1,5- or 2,6-naphthylene.
- X is an electron-withdrawing group, preferably carbonyl or sulfonyl, while Y represents another group such as O, S, CH 2 , isopropylidene or the like.
- at least 50%, preferably at least 70% and particularly preferably at least 80% of the groups X represent a carbonyl group, while at least 50%, preferably at least 70% and particularly preferably at least 80% of the groups Y should consist of oxygen.
- the PAEK may be, for example, a polyetheretherketone (PEEK; Formula I), a polyetherketone (PEK; Formula II), a polyetherketone ketone (PEKK; Formula III), or a polyetheretherketone ketone (PEEKK; Formula IV), but of course other arrangements are contemplated the carbonyl and Oxygen groups possible.
- the PAEK is generally semicrystalline, as evidenced, for example, in the DSC analysis by finding a crystalline melting point T m , which is of the order of magnitude of 300 ° C or higher in most cases.
- T m crystalline melting point
- the teaching of the invention is also applicable to amorphous PAEK.
- sulfonyl groups, biphenylene groups, naphthylene groups or bulky groups Y such as.
- As an isopropylidene group reduce the crystallinity.
- the viscosity number measured according to DIN EN ISO 307, on a solution of 250 mg PAEK in 50 ml of 96% by weight H 2 SO 4 at 25 ° C, about 20 to 150 cmVg and preferably 50 to 120 cmVg.
- the BET surface area is determined according to DIN ISO 9277.
- the porous PAEK can be ground at room temperature or elevated temperature, but to improve grinding and milling yield it is advantageous to ground at a lower temperature, preferably below 0 ° C, more preferably below -20 ° C, and most preferably below ⁇ 40 ° C.
- a lower temperature preferably below 0 ° C, more preferably below -20 ° C, and most preferably below ⁇ 40 ° C.
- pin mills fluidized bed counter-jet mills or baffle mills are suitable.
- the porous structure of the PAEK to be grounded provides weak points which lead to breakage under the abovementioned conditions.
- the regrind can be subsequently screened or sieved.
- a finely powdered PAEK having a number average particle diameter (d 50 ) of 1 to 300 .mu.m, preferably from 4 to 200 .mu.m, more preferably from 10 to 150 .mu.m, particularly preferably from 15 to 120 .mu.m and very particularly preferably from 20 to 100 microns are obtained.
- the determination of the particle diameter and its distribution is carried out by laser diffraction according to DIN ISO 13320-1.
- the PAEK powder can then additives such.
- inorganic pigments such as titanium dioxide, carbon black and the like or processing aids may be added, for example as a dry blend.
- the ultrafine powdery PAEK thus obtained can be used for coating, e.g. As of metal (eg., Steel) or ceramic objects by means of electrostatic coating, vortex sintering or
- Coating with a PAEK suspension in water can be used. In these cases can it as an inorganic processing aid z.
- Example 1 Particles of PEEK with a BET surface area of 50 m 2 / g and an average grain diameter of 500 ⁇ m were ground using a cryogen-working pin mill (Hosokawa Alpine CW 160).
- the PEEK particles were conveyed via a screw conveyor into a grinding chamber and, in the meantime, cooled down to - 50 ° C with liquid nitrogen.
- the PEEK particles were accelerated by rotating pin disks to 220 m / s. At this speed, they impacted the pins on the pin disks, exposing them to strong impact, causing the particles to break. This happened with a throughput of PEEK particles of 15 kg / h.
- the grinding chamber left a micronized product with a proportion of particles smaller than 100 microns of 30 wt .-% (sieve analysis with Alpine air jet sieve according to DIN EN ISO 4610).
- the process cut of separation followed.
- the crushed PEEK particles were fractionated using an Alpine air jet screen with a downstream cyclone.
- the fractionation was carried out at a mesh size of 80 microns.
- the powder thus obtained was characterized by a d 10 of 16.7 ⁇ m, d 50 of 52.6 ⁇ m and d 90 of 113.8 ⁇ m.
- Example 2 The procedure was as in Example 1, but with a throughput of 20 kg / h.
- the grinding chamber left a micronized product with a proportion of particles smaller than 100 microns of 30 wt .-%. After micronization, the process intersection of separation took place.
- the crushed PEEK particles were fractionated using a zigzag sifter.
- the operating parameters of the zigzag sifter were: revolutions 10,000 min -1 , drag air 65 mVh
- the powder thus obtained was characterized by a d 10 of 8.5 ⁇ m, d 50 of 21.4 ⁇ m and d 90 of 54.9 ⁇ m.
