Definitions

  • the present invention relates to a method for producing a composite body.
  • Such composites often consist of a support layer of acrylonitrile-butadiene-styrene copolymers (ABS) on which a top layer of polymethyl methacrylate (PMMA) is disposed to improve the weathering properties, surface hardness, gloss and chemical resistance of the composite.
  • ABS acrylonitrile-butadiene-styrene copolymers
  • PMMA polymethyl methacrylate
  • the composite bodies are usually produced by coextrusion of all layers or lamination, to which the thermoforming or hot edge of the composite board produced in this way can be added to form a shaped body.
  • Generic composites can be used anywhere where the replacement of painted surfaces by co-extruded or laminated surfaces is desired, for example in the sanitary sector, motor vehicles, commercial vehicles, furniture, refrigerators and in the advertising industry.
  • Composite bodies with a cover layer of PMMA have the problem that they need to be improved in terms of abrasion and scratch resistance, dirt repellence and chemical resistance to painted surfaces.
  • the object of the invention is to provide a generic composite body in which the surface properties of the PMMA cover layer are improved by a permanent, resistant to external influences enrichment of polyorganosiloxanes in the outer region of the PMMA cover layer.
  • the extruded or laminated composite is deep-drawn or hot-edged into a molded article.
  • the invention is based on the surprising discovery that the molecules of the organometallic compound compounded into the PMMA mass by heating the mass, for example by the process of coextrusion or lamination, due to the surface activity of the long-chain organic compounds with the organometallic part, which oriented in air, can migrate to the surface of the PMMA mass and so form a molecular film, which causes the desired physicochemical properties.
  • the organic moiety of the macromolecule is physically entangled in the PMMA matrix, making wiping the layer physically and chemically impossible. This shows that the concentration of the organometallic compound in the PMMA mass is greatest in the region of its surface.
  • the migration of the organometallic molecules to the surface takes place optimally when the layer formed from the PMMA and the organometallic compound has a temperature above the glass transition temperature of the PMMA, which is exceeded anyway during coextrusion or lamination, since the polyorganosiloxanes are not yet firmly in the Inside the layer formed from the PMMA and the organometallic compound are incorporated. If necessary, can also be heated externally, for example, in a deep drawing process.
  • a lamination film must first be produced by (co) extrusion.
  • the PMMA and the organometallic compound can either be homogenized in situ or a precompound is prepared. Subsequently, in both cases, the lamination.
  • the preparation of the polymer compound can be carried out, for example, by mixing the PMMA and the organometallic compound in the screw of an extruder. This eliminates an additionally required process step, since the PMMA must be extruded anyway. It is also possible to re-granulate the polymer compound of PMMA and the organometallic compound after its formation and before coextrusion or lamination.
  • the invention also relates to a composite body having at least one cover layer and a further layer, as produced, for example, by the method described wherein at least one of the further layers comprises at least one of the following polymers: PS, ABS, PMMA, HI-PMMA, ASA, PC, PC-PET (G), PC-PBT, ABS-PC, ASA-PC, ABS PA or mixtures thereof, and the at least one cover layer of - preferably impact-modified - PMMA and an organometallic compound - preferably polyorganosiloxane - exists.
  • a composite body can be produced from the composite body by deep drawing or hot edges.
  • the composite has at least two, preferably three or five, layers, wherein at least one cover layer consists of PMMA and the organometallic compound and at least one of the further layers consists of one of the following polymers or mixtures thereof : PS, ABS, PMMA, HI-PMMA, ASA, PC, PC-PET (G), PC-PBT, ABS-PC, ASA-PC, ABS-PA.
  • both cover layers of the composite body consist of PMMA and the organometallic compound. This is especially advantageous when the layers arranged between the cover layers consist of PMMA.
  • the composite body then consists entirely of acrylic, with its surfaces having the desired properties.
  • particularly advantageous mechanical properties and surface properties result if the total thickness of the composite body is 0.05 to 13 mm and the thickness of the further layers is 0.01 to 9 mm in each case.
  • the main extruder layer (the thickest layer) may be 4 to 9 mm thick.
  • Example 1 relates to a coextruded composite panel.
  • Example 2 relates to a laminated composite panel,
  • Example 3 relates to further coextruded composite panels:
  • Example 1 :
  • a sanitary panel produced by the method according to the invention consisting of an ABS / PMMA composite, having a 5% coextruded PMMA top layer (relating to total thickness, for example a PMMA top layer of 200 ⁇ m at 4 mm total plate thickness, was tested ): In this top layer, 2.5 percent by weight of polyorganosiloxane were incorporated.
  • the incorporation on the extruder can be done by various methods.
  • Tests were carried out on the extruded plate and on the deep-drawn part.
  • the deep-drawn part was deep-drawn by default with a PE protective film. Checked was on
  • Used Scratch Resistance Tester Universal Scratch Tester Model 413 from Ericsson.
  • the test device consists of a frame with a movable support surface. This support surface can be moved from the horizontal at a constant tilting speed (via an electric motor) to the vertical. It measures the angle at which a arranged on the support surface support weight begins to slip.
  • the bearing surface sliding surface
  • the contact surface is 63 x 63 mm.
  • As a support weight a steel weight was used with a net weight of 504 grams.
  • the sample to be tested (plate) is placed on the support surface, which is in the 0 ° position, with the surface to be tested upwards (about DIN A4, thickness between about 1 - 6 mm).
  • the steel weight is placed with the felt covering.
  • the support surface driven by an electric motor, moves uniformly around the fulcrum. In the range of 0 ° to 50 °, a uniform lifting speed of about 37 sec. respected.
  • a protractor is attached to the inclination of the support surface can always be checked.
  • the test person moves the support surface by pressing a button around the fulcrum, constantly monitoring the weight.
  • the button for the lifting drive is released, whereby the support surface is stopped in the upward movement ung.
  • the contact angle and surface tension were determined on ABS / PMMA sheets of the type described above with addition of 2.5% and 5% polyorganosiloxane, respectively.
  • the surface energy and the contact angle of composite bodies according to the invention were determined before and after deep-drawing.
  • test fluids water, glycerol, ethylene glycol, 1-octanol and n-dodecane.
  • the measurement is carried out with a contact angle measuring device from Krüss (G2).

With the contact angle measurements of the liquid drops on the surface of the solid polymers, both the total surface tension of the solid and the polar and dispersive fractions can be determined.

As support surface, a 63 x 63 mm sliding surface made of felt was used. The weight was 504 g. The sliding friction on deep-drawn parts was measured to simulate the deep-drawing process.
