Definitions
- the invention relates to a molded plastic body comprising a polymer phase formed from a curable reaction mass and a particulate filler material embedded therein.
- plastic moldings have long been manufactured as kitchen worktops, kitchen sinks, sanitary parts and the like or used as materials for the production of such parts.
- plastic moldings replace natural materials such as. B. marble, granite, etc., which are characterized by their special optical aesthetic appearance.
- fillers are either inorganic fillers in the form of granite powder or sand, quartz powder or sand or other minerals with a fine to coarse grain structure, or else particulate polymer-based fillers, which in turn contain inorganic fillers.
- inorganic fillers in the form of granite powder or sand, quartz powder or sand or other minerals with a fine to coarse grain structure, or else particulate polymer-based fillers, which in turn contain inorganic fillers.
- the object of the present invention is to propose a molded plastic body with such greater similarity to natural materials.
- the filler material comprises a resin material filled with an inorganic filler, the polymer phase comprising up to 60% by weight, based on the plastic molded article, of inorganic additive particles, the filler material having a grain size in the range has from 60 to 8000 ⁇ m and is contained in the plastic molded body in a proportion of approximately 5 to approximately 75% by weight, and the filling material comprises at least 10% by volume of particles which have two or more differently colored, superficially visible polymer layers .
- the filler material which comprises a resin material filled with an inorganic filler, at least 10% by volume of the filler material particles having two or more differently colored, superficially visible polymer layers, a clear advance in the approach to natural materials is achieved.
- the two or more differently colored, superficially visible polymer layers come closer to the natural model, since inclusions can also be found in natural stones that are not evenly colored.
- Preferred plastic moldings have a filler material in which at least one of the two or more differently colored, superficially visible polymer layers is transparent or translucent. The consequence of this is that, due to the increased light permeability of such particles or particle layers, the light incident from the surface can penetrate deeper into the plastic molded body and thus virtually amplify the color effect of the surface. Similar inclusions and similar optical effects also show natural materials, so that this preferred plastic molded body comes very close to natural materials. A sophisticated play of colors is created here, which leads to a high aesthetic value of these materials.
- a further approximation to the natural fillers is achieved when the particles of the filler have a broken grain shape.
- the inclusions in natural materials very often have broken grain shapes, so that a further approximation to the natural model is achieved here.
- the particulate filler material which is based on a resin material filled with an inorganic filler, is preferably first produced as a multilayer plate material, which is then comminuted, in particular ground, into the filler material particles.
- the curable reaction mass used for the formation of the polymer phase can be selected from a large number of known reaction mass systems, preferred curable reaction masses comprising a first monomer / prepolymer syrup.
- the polymer phase itself can be an acrylate polymer, a polyester or an epoxy resin, the acrylic polymer matrix being in is the preferred alternative in terms of price / performance ratio.
- the inorganic fillers used both for the filler material and as additional aggregate particles for the polymer phase are, as is known per se, granite, quartz or other mineral sands or flours, the filler being aluminum trihydroxide, chalk, talc and barium sulfate, in particular.
- H. soft fillers with a Mohs hardness of three to five degrees of hardness are preferred. This leads to a simple machinability of the molded plastic body which can be carried out with little tool expenditure.
- Fillers other than those mentioned above are in principle just as possible as the aforementioned soft fillers, but because of their hardness they generally require diamond-coated tools for machining the shaped bodies, so that they can therefore only be machined at high cost.
- the prepolymer content in the first syrup is preferably about 5 to about 30% by weight, based on the syrup.
- the viscosity of the first syrup is preferably set to approximately 20 to approximately 300 mPa, so that the mixture of syrup and filler material is easy to process in the production of the plastic moldings.
- the prepolymer of the first syrup preferably has an average molecular weight of approximately 20,000 to approximately 300,000 Da, a value which optimally allows the viscosity of the syrup to be moderated.
- such prepolymers already offer one sufficient effect in the shrinkage change during curing, with the acrylate polymers in particular being considered here.
- the first syrup preferably further comprises a free-radically polymerizable monomer, as stated above, in particular of the acrylate type, which in particular means acrylate and methacrylate monomers.
- the associated prepolymer is preferably used as a homopolymer or copolymer of the aforementioned monomers.
- the particulate material is selected to be swellable in the curable reaction mass and the filled resin material (at least in its filler particle-containing and non-transparent or translucent layers) has a filler range of 50 to 80% by weight with a grain size of approx. 5 to approx. 100 ⁇ m.
- particulate filler material is allowed to swell in the curable reaction mass, a mass which is no longer flowable and can be pressed into molds is obtained, in which the filler material with its proportion of multilayer filler particles is pressed against the visible side surface by pressing in the mold. This ensures that a sufficient proportion of multi-layer filling material particles is visible on the surface and can thus sufficiently serve the effect of simulating natural materials.
- particulate filler materials are used in conjunction with, for example, approx. 40 to 60% by weight of inorganic additives, a flowable and pumpable dispersion of the fillers and additives in the reaction mass is obtained, which in a mold can be cast, where it can happen that Depending on the recipe, not enough of the multilayer filler particles are visible on the surface. Machining or at least abrasive processing of the surface is then recommended here in order to allow a sufficient number of the multilayer filler material particles to be visible on the visible side surface of the plastic molded body.
- the resin material of the filler material is preferably produced from a second monomer / prepolymer syrup which contains a proportion of approx. 5 to approx. 30% by weight prepolymer with an average molecular weight in the range from approx. 20,000 to approx. 300,000 Da.
- the filler for this resin material of the filler material is preferably aluminum oxide trihydrate, although the above-mentioned alternatives based on granite, quartz and other are also suitable, optionally in a mixture with aluminum oxide trihydrate (ATH).
- ATH aluminum oxide trihydrate
- the aluminum oxide trihydrate is preferably coated with a silane in an amount of 0.04 to 1% by weight, based on the weight of the aluminum oxide trihydrate. This serves to securely couple the filler particles to the surrounding phase made of resin material.
- preferred second monomer / prepolymer syrups have a crosslinking agent in a proportion of approximately 0.5 to 5% by weight, based on the total weight of the syrup. These proportions of crosslinking agent suggest a sufficient strength of the filler particles, on the other hand, however, the crosslinking is not yet carried out to such an extent that swellability is too low.
- Bifunctional or polyfunctional acrylate crosslinkers are used primarily as crosslinkers in the second monomer / prepolymer syrup.
- the particulate filling material is preferably composed of a mixture of different granular filling materials. This makes it possible to achieve even more diverse effects and, particularly in special cases, a further approximation to the natural models.
- the invention further relates to a process for the production of plastic moldings as described above, wherein a mixture of a curable reaction mass is produced to form a polymer phase with a particulate filler material and is put into a mold for curing, the curable reaction mass up to 60% by weight.
- the filler used being a filler material which may swell in the reaction mass and which comprises a resin material filled with an inorganic filler, the filler material having a grain size of from 60 to approximately 8,000 ⁇ m, a proportion of the filler material of at least 10% by volume is formed from particles which have two or more differently colored, superficially visible polymer layers, and the filler material is metered in such a way that it contains from about 5 to about 75% by weight in the plastic molding is and wob Finally, the mixture is placed in a mold for hardening and thermally hardened there.
- Figure 1 the visible side of a molded plastic body according to the invention.
- Figure 2 the visible side of a further molded plastic body according to the invention.
- the molded plastic body 10 according to the invention from FIG. 1 has a continuous polymer phase 12 formed from a curable reaction mass, which, embedded therein, comprises a color-contrasting, particulate filling material 14.
- the individual particles of the filling material 14 have a broken grain shape and, moreover, two or more differently colored, superficially visible polymer layers. Due to these contrasting * color effects, a very good approximation to natural materials, i. H. Natural stones such as granite.
- FIG. 2 shows a visible side of a molded body 20 according to the invention, in which a continuous polymer phase 22 also contains filler particles 24 that contrast in color.
- a continuous polymer phase 22 also contains filler particles 24 that contrast in color.
- the color-contrasting filler material particles are made up of two or more differently colored, superficially visible polymer layers, with some of the polymer layers of the filler material particle being transparent. This gives this material an optical depth and an even stronger effect when approaching natural materials.
- layer granules are preferably used as the particulate filling material in which a colored, ie filler and pigment Alternate ment-containing component or polymer layer and a transparent polymer layer.
- a colored, ie filler and pigment Alternate ment-containing component or polymer layer and a transparent polymer layer are preferably used as the particulate filling material in which a colored, ie filler and pigment Alternate ment-containing component or polymer layer and a transparent polymer layer.
- two differently colored, filler-containing or filler-free casting resins are first produced from the components required in each case, which are poured from thin nozzles into a type of baking tray with an oscillating movement. Care is taken to ensure that as many phase boundaries as possible arise between these two cast resin strands.
- the viscosity of the two casting resins is designed so that mixing is essentially avoided. Suitable viscosities are, for example, in the range from 6,000 to 40,000 mPas, preferably around 10,000 Pas. After the "cake pan" is filled, the mass is cured in a press.
- a granulate is formed, the particle size of which is chosen between 60 and 8,000 ⁇ m.
- the granules visibly show a layering of, for example, transparent and colored material.
- These particles are now suitable as fillers in the sense of the present invention for the production of plastic molded parts, for example plates or other molded parts, such as kitchen sinks, sanitary parts or the like.
- different granules with differently colored layer components can be used. This is how materials are created that meet an extremely high optical standard.
- the special effects of the layer grain in the plastic moldings according to the invention can be described as follows:
- a play of colors can be achieved in particular through the transparent portion of a layer granulate, in which the color impression of the background color is enhanced, similar to a light guide.
- the layer granulate particle is from the surface, i. H. A little below the surface, completely submerged below the surface or directly on the surface, there are diverse optical effects.
- the stratification is formed in the particle, whether the stratification is oriented perpendicularly, obliquely or parallel to the surface, there are other optical effects, which results in an additional enrichment of the optics.
- Component A for a transparent or translucent polymer layer is used with an average percentage of the total mass of layer grain of 20 to 80%, particularly preferably approx. 40%, the total mass having a viscosity of 6 to 40 Pa s.
- a specific example recipe for component A consists of 93.4% syrup (70% MMA, 30% PMMA (100,000 Da)), 3% pyrogenic silica (Aerosil R 812 S), 2% TRIM as crosslinker, 0 , 5% BCHPC as the first peroxide, 1% LP as the second peroxide and 0.1% stearic acid as a mold release agent.
- the viscosity of a recipe composition composed in this way is approx. 10 Pa s.
- Components Bl. B2. ,,, Bn for polymer layers colored in different colors (1, 2, ... n) are used with a total average percentage of the components in the total mass of the layer grain of 20 to 80%, preferably approx. 60%, if as further layer polymer component, component A (transparent or translucent) is used. This results in a viscosity of the total mass of 6 to 40 Pa s.
- the viscosity of a composition mass composed in this way is approx. 10 Pa-s. Pigments Depending on the desired color effect, they can also be added to the recipe mass at your own discretion.
- the two casting compounds are filled into a mold via fine multiple nozzles (approx. 1 to 3 mm 0).
- the diameter of the nozzles determines the number of phase boundaries or the thickness of the layers in the layer granulate.
- the mass is hardened in a press under pressure and temperature:
- the plates After cooling, the plates are ground and sieved into several layer granulate fractions.
- the proportion of particles which has two or more differently colored, superficially visible polymer layers is always far above the lower limit of 10% by volume required for the effects according to the invention.
- a pumpable and pourable curable reaction mass made of acrylic resin, acrylate monomer and ATH is produced (cf., for example, DE 40 40 602 AI) and the particulate filler material (layer granules) is admixed with it.
- the viscosity of the casting compound is preferably in the range from 5 to 80 Pa »s.
- the viscosity of a recipe composition composed in this way is approx. 30 Pa s.
- the total solids content in the molded plastic body is preferably approximately 50%.
- a casting compound with a high proportion of polymer granulate is produced. This is still fluid at the beginning, but changes its consistency due to a swelling process. After an hour, a non-pourable mass (viscosity 100 to 1,000 Pa s) is formed, which is introduced into the mold and pressed under high pressure.
- the viscosity of such a compound composition is approx. 500 Pa s.
- a preferred solids content of the entire molded body is approximately 45%.
- Component A transparent:
- Component B2 (black):
- Component B3 (orange):
- Component B4 (green):
- the polymer granules white and blue used in the present example and also in the following are produced, ground and sieved into fractions analogously to the recipes for the individual color components B1, B2, ... with the appropriate color setting, as indicated in the tables.
- the mass is 10 min. mixed long and 10 min. long degassed. Then wait until the mass has swollen and can be pressed and hardened in a press without further sedimentation problems.
- the surface obtained in this way is similar to that shown in FIG.
- the reaction mass polymer phase 22
- the mass is 10 min. mixed long and 10 min. long degassed. Then wait until the mass has swollen and can be pressed and hardened in a press without further sedimentation problems.
- the material with the layer granulate from Example 5 is distinguished from the result from Comparative Example 1 by a significantly improved visual appearance.
- the layer granules can be ground off.
- the mass is 10 min. mixed long and 10 min. long degassed. Then wait until the mass has swelled. Then the mass is pumped into casting molds and hardened under pressure and temperature.
- the one available here Surface is again similar to that obtained in Example 5.
- the mass is 10 min. mixed long and 10 min. long degassed. Then wait until the mass has swelled. Then the mass is pumped into casting molds and hardened under pressure and temperature.
- the material with the layer granulate according to Example 6 is distinguished by a significantly improved optical appearance compared to the result of Comparative Example 2. If the optical properties are to be emphasized even more clearly, i. H. To "uncover" the granules, approx. 100 to 500 ⁇ m material can be ground off.
