Definitions
- the invention relates to a method for
- Pearl polymers are used in various industries, such as in engineering and medicine, as an additive to other plastics or ceramics to produce new products or to optimize their manufacturing or product properties.
- bead polymers In the production of ceramic substrates, bead polymers have hitherto been added to the ceramic raw materials which were thermally removed in the further processing.
- the temporarily added polymers should serve to create a definable porosity in the ceramic body.
- bead polymers was chosen because these are in the ceramic starting material, such as
- Slip, paste or dough have a particularly low fluid requirement. As a result, unwanted shrinkage properties are avoided.
- Another advantage of the bead polymers is that they can be produced in exactly definable grain sizes.
- This effect is based on the partial tearing of the bead polymers from the composite of the entire matrix. In particular, this effect has been shown in still moist components. The abrasion resistance of the thermally untreated blanks has proved to be inadequate for many applications.
- precipitation polymers or mechanically broken bead polymers leads to an increased fluid requirement, along with a significant decrease in plasticity and consequently does not meet the desired requirements.
- the invention is therefore based on the object to provide a method by which perl polymers are treated in a particularly simple and effective manner so that they have a relatively low fluid requirement and addition to ceramic blanks in particular, their plasticity does not reduce, but their strength and dimensional stability increase.
- this object is achieved in that the bead polymers are fed to a comminution device, in particular a mill, in which the surface of the bead polymers is deliberately mechanically mechanically scratched or roughened.
- the bead polymers are processed by means of a comminution device such that the crushing effect is largely suppressed, the individual grains of the bead polymer have on their surface after processing evenly distributed scratch marks with a predetermined depth.
- This has the advantage over chemical processing, for example by etching, that no chemical residues remain, which can influence the further processing sequence.
- the starting material receives a corresponding pore formation by the voids formed in the ceramic matrix by the polymer.
- Splitting, baffle or whip mills are particularly well suited by a targeted selection of treatment parameters, such as duration of use and operating speed of the respective processing tools, not to break the bead polymers, but simply scratch or roughen it superficially.
- This improves in particular the adhesion of the individual bead polymer body, for example by snagging or greater friction of the body in or with the Matrix. The result is an improved grip and bond as well as an increased strength.
- the bead polymers or the comminution device are preferably cooled.
- added cooling or refrigerant can be used, which are then removed again.
- the bead polymers are cooled before and / or during the feed.
- Such surface-treated bead polymers preferably as a void and / or as a pore or channel former in ceramic compositions.
- the use of bead polymers in this field is common.
- pearl polymer is thereby Usually polymethyl methacrylate (PMMA) used.
- PMMA polymethyl methacrylate
- the polymer grains are mixed on site mostly with an X-ray contrast agent, a starter system and possible active ingredients with the matrix liquid, the monomer of the polymer.
- the cement hardens, the polymer granules are incorporated into the solidifying matrix of the monomer, as well as the other ingredients.
- Bead polymers by torn polymer beads from the cement matrix are thus avoided by the use of such surface-treated scratched or roughened bead polymers. This is of particular importance for a desired, long-lasting or permanent retention of the implants in the body.
- the surface-treated by the novel bead polymers preferably find use as a filler in the paint and paint industry.
- These special paints and colors are characterized by the scratched or roughened pearl polymers in particular by improved abrasion resistance.
- Another particularly advantageous use of such surface-treated bead polymers is the use as a surface coating, in particular because of the anti-slip effect of such coverings.
- a commercially available bead polymer based on methacrylate with an average particle size of 40 ⁇ xn is briefly cooled and then ground in a disc mill - similar to a flour mill - in which the disc gap is set contact-free, in one or more passes, the Mahlstein effet and Mahlsteinabstand are adjusted so that no or only a minor comminution of the material to be scraped, the bead polymer occur.
- the polymer thus treated is added to the ceramic raw material as a filler and pore former, which is then treated conventionally.
- Embodiment 2 is a diagrammatic representation of Embodiment 1:
- a commercially available pharmaceutical grade polymethyl methacrylate is scratched as a bead polymer in a pin mill on the surface of the polymer beads.
- the rotational speed of the pins of the pin mill, the flow rate of bead polymer and optionally the added amount of air as a transport and coolant is set such that no or only an insignificant crushing effect occurs and the polymer grains are scratched only superficially.
- the polymer thus obtained is mixed with the others Cement components - for bone cement or dental cement - blended and mixed in the application with the monomer and cured, with the use of so-called light curing can be used.
- a dyed bead polymer with incorporated electrically conductive constituents is treated in an impact mill in such a way that the impact speed is below that
- the baffle is cooled in order to prevent thermal deformation of the polymers.
- the thus surface-scratched polymer part is added to a paint as a filler, which in turn is conventionally processed, an abrasion-resistant electrically conductive protective layer.
- a very low viscosity bead polymer is cooled such that it freezes for a short time, thereby achieving sufficient hardness to scratch it in a cone-and-slot mill on the polymer surface. Subsequently, it is applied as an anti-slip coating in or on a surface to be coated and bonded to this.
- the resulting coating can be kept extremely thin due to the surface texture of the polymer parts, since the adhesion to the substrate is very pronounced.
