Definitions
- the invention relates to moldings of a transparent plastic matrix with small amounts of embedded, very finely divided plastic particles having a particle diameter smaller than the wavelength of visible light, as well as the use of these moldings for the visualization of laser beams and for lighting purposes.
- the whitening of plastics is generally accomplished with inorganic pigments of high refractive index, such as e.g. Titanium dioxide used. Although high coverage is generally achieved, this is often accompanied by an undesirable reduction in light transmission.
- inorganic pigments of high refractive index such as e.g. Titanium dioxide used.
- Organic light scattering agents such as e.g. Crosslinked plastic particles of a certain particle size with a refractive index differing from the matrix show this
- Particularly suitable for the tarnishing of plastics are the 2- 15 .mu.m particles with core-shell structure mentioned in EP 269 324. These particles, incorporated in a plastic matrix, give shaped articles with a high transparency, they scatter the light so that the light source is not visible. Such, substantially forward scattering scattering particles can be used with advantage for the production of light guide plates, which are illuminated from the edge ago (DE 93 18 362).
- Finely divided plastic particles with a rubber core and a hard shell are widely used as impact modifiers.
- the refractive index of the rubber phase e.g., polybutyl acrylate
- the refractive index of the matrix is matched to the refractive index of the matrix by copolymerization with styrene.
- DE 38 42 796 teaches that in the case of core-shell particles with a rubber particle diameter ⁇ 130 nm at a fraction of 10 to 90% by weight of rubber phase distributed in 90 to 10% by weight of hard phase, clear products are obtained even if rubber phase and hard phase one Have refractive index difference of> 0.02.
- moldings are particularly well suited, which consist of a crystal-clear matrix plastic A and distributed therein contain organic plastic particles B with core-shell structure, wherein the core of the plastic particles is crosslinked, the shell at least partially connected to the core and the shell material with the matrix plastic A is miscible.
- the refractive index of the core material of the plastic particles B deviates by 0.06-0.4 from the refractive index of the matrix plastic A.
- the diameter of the core of the plastic particles B is ⁇ 0.2 .mu.m and the proportion of the plastic particles B relative to the matrix plastic A is 0.0001-5 wt.%.
- Essential for a high transparency of the molded articles with at the same time good visualization of laser beams is a refractive index difference of the core of the scattering particles B to the matrix plastic A in the range 0.09-0.3 and a good distribution of the plastic particles B in the matrix.
- the proportion of plastic particles B in the matrix is important for most applications. Due to the good distribution in the matrix plastic, the fineness and the proportion of particles in the ppm range, the shaped bodies according to the invention are almost crystal clear, the laser beam is hardly attenuated, but is still clearly visible.
- moldings of interest There are 2 types of moldings of interest. These are on the one hand moldings with a matrix A of polyacrylate and
- Plastic particles B which are combined with a PMMA matrix, contain cores with a refractive index> 1.57, as obtainable by copolymerization of styrene with crosslinkers.
- other aromatic monomers containing monomers are suitable, such as vinyl naphthalene.
- a shell material of particles B In this case, a PMMA matrix, PMMA itself, which is at least partially connected to the core, is in question (see below).
- the second type of moldings according to the invention are moldings having a matrix A of polystyrene, bisphenol polycarbonate, e.g. Bisphenol A polycarbonate or aromatic polyester, e.g. As polyesters of alkylene terephthalate.
- the shell material of the plastic particles B consists of vinyl polymers that are compatible with the matrix polymer A mentioned.
- Suitable shell material for a matrix of polystyrene are, for example, copolymers of 60 parts of MMA and 40 parts of cyclohexyl methacrylate (DE 36 323 69) or, of course, polystyrene itself.
- a shell material of the plastic particles B suitable for blending with bisphenol A polycarbonate is a copolymer of MMA and phenyl methacrylate, which is compatible with this polycarbonate (DE 37 192 39).
- copolymers of styrene and MMA are suitable as shell material in this case.
- These shell materials can also be used for a plastic matrix of aromatic polyesters. In the case of this aromatic plastic matrix having a comparatively high refractive index, e.g. B. n D 20> 1.57, one chooses cores of the polymer particles with the lowest possible refractive index.
- the plastic particles B are The plastic particles B.
- the plastic particles B are core-shell particles, as they are readily accessible by emulsion polymerization (see, for example, DE 198 20 302). In principle, these plastic particles consist of 2 different polymers with correspondingly different functions.
- the core of the particle which differs from the matrix plastic with regard to the refractive index, represents the light scattering element, and the shell is responsible for a good distribution and anchoring of the particles in the matrix.
- the core is characterized essentially by the difference of the refractive index to the matrix material ⁇ n and by the size. In this case, ⁇ n is in the range 0.06-0.4, preferably in the range 0.09-0.3.
- the cores are spherical particles with a diameter in the range 0.02-0.2 ⁇ m, preferably in the range 0.04-0.15 ⁇ m.

- the concomitant use of a minor amount, e.g. 0.01-10% by weight of crosslinkers having 2 polymerizable groups of different reactivity (graft crosslinker), e.g. Allyl methacrylate.
- graft crosslinker e.g. Allyl methacrylate.
- the shell of the plastic particles Bl for blending with PMMA is preferably composed of MMA and minor proportions, e.g. 4 wt.% Cl - C4 esters of acrylic acid to reduce depolymerization tendency.
- the polymerization of the shell is carried out by the emulsion or monomer feed process, wherein also polymerization regulators such. Mercaptans can be used, this improves the meltability of the shell and facilitates the distribution of particles in the matrix.
- plastic particles having a core with a high refractive index plastic particles with a low refractive index, n D 20, for example, are selected for mixing with the higher-refractive aromatic matrix plastics A2 1.50.
- Suitable core materials of the plastic particles B2 are obtained, for example, by copolymerization of> 80 parts of MMA, 1 to 19 parts of acrylic acid esters such as ethyl acrylate and 0.1 to 10 parts of crosslinking agents such as butanediol diacrylate.
- shell material - as shown above - vinyl polymers are used, which are compatible with the plastic matrix A2.
- a shell material of 90 parts MMA and 10 parts phenyl methacrylate is used (DE 37 192 39).
- the weight ratio of core to shell is in the range from 3: 1 to 1:10, preferably in the range from 2: 1 to 1: 5.
- the core of the plastic particles B is crosslinked and dimensionally stable. Preference is given to cores having a glass transition temperature> 60 ° C.
- plastic matrix A and plastic particles B can be carried out according to 2 different methods in principle.
- this is the casting process.
- the plastic particles B are isolated from the aqueous latex as a solid and dispersed in the monomer matrix which builds up the plastic matrix A.
- the resulting particle-monomer mixture is finally poured into a mold and polymerized.
- This method is suitable, for example, for a plastic matrix of polyacrylate or polymethacrylate.
- This process is of particular interest when crosslinked molded articles are to be produced, for example, soft molded articles made of crosslinked! Polybutyl. (For the production of moldings of PMMA according to this method according to this method, see Example 3, for carrying out polymerizations by the casting process, see eg Kunststoff-Handbuch IX, p. 15, Carl Hanser Verlag 1975).
- the second method, the plastic particles B and the plastic matrix A to mix is to isolate the plastic particles B from the latex and mix with molding material of matrix plastic A.
- a matrix resin molding compositions of the conventional molding materials used for extrusion or injection molding are used, for example in the case of the matrix plastic PMMA for injection molding purposes, the injection molding composition Plexiglas ® 7N by Rohm GmbH.
- Plastic Particle B solid, at least a portion of the matrix molding composition may be added in the form of a molding compound A latex (for the preparation of molding composition by emulsion polymerization, see DE 36 12 791). This facilitates the distribution of the plastic particles in the matrix plastic.
- the blending is recommended in two stages.
- a 1st stage granules of thermoplastically processable
- the shaped articles according to the invention are generally transparent with a light transmission of e.g. > 80%.
- the moldings according to the invention are highly transparent. You can see through it without a problem.
- the moldings show at best a slight blue cast, caused by the increased scattering of the short-wave light components (sky blue).
- Moldings of pure matrix plastic A are optically empty, a light beam is not visible in this matrix, a light beam is at best perceived by its reflected at the interfaces of the molding body. In contrast, a light beam is excellently visible in the moldings according to the invention.
- the plastic particles B in the matrix A are a targeted, homogeneously distributed impurity which scatters the light.
- the main application of the shaped bodies according to the invention lies in the combination of the shaped bodies according to the invention with light of narrow wavelength distribution, in particular in combination with lasers or laser diodes.
- the moldings of the invention in the field of security applications.
- a laser beam through the moldings can be easily visible without weakening it appreciably.
- the ray path can be tracked well.
- the shaped bodies according to the invention are used in the field of measuring technology, for example as aids for
- the shaped bodies 2 should have plane-parallel surfaces such that the laser beam is not changed in its course by the shaped body.
- Another application is in the field of teaching.
- Shaped bodies with a thickness of> 1 mm, preferably with a thickness in the range of 3 to 8 mm, in which at least 1 part of the shaped body is designed as a circular segment, are particularly suitable here.
- the course of the laser beam in these shaped bodies makes it easy to display properties of light such as refraction, reflection, total reflection.
- red-light lasers e.g. 650nm wavelength lasers are of interest.
- Such systems find e.g. as a laser pointer wide application.
- shaped bodies according to the invention Another field of application of the shaped bodies according to the invention is the field of illumination with narrowly distributed or monochromatic light.
- these shaped bodies can be used as edge-illuminated light-guiding elements for monochromatic light. It is of interest that those distributed in the matrix
- plastic particles are very finely divided, so that these moldings can be produced as very thin films.
- this edge-illuminated planar lighting element as a vehicle rear light or as a brake light, it is advantageous to mirror the back of this element.
- planar lighting elements is the fact that of these Elements outgoing light is polarized. Thus, this light can be distinguished from the light emanating from another light source.
- the second half of the monomer mixture (M-core) was added and heated again to 70 0 C.
- the monomer mixture (M-shell) consisting of 61.8 g of MMA and 1.3 g of ethyl acrylate is added over a period of 15 minutes. Then allowed to stir for a further 15 minutes at 70 0 C and finally heated for 45 minutes at 90 0 C. After cooling results in a finely divided dispersion. Solids content: 13.5%. Diameter of the core about 100nm.
- the Kunststoffpumble- latex according to Example 1 is frozen at -20 0 C and thawed with 80 0 C warm water. After aspirating the coagulum solid and drying at 30 0 C results in a powdery solid.
- Molded body based on PMMA with 0.033% by weight of plastic particles B 30 mg of the plastic particle solids according to Example 2 are dispersed by means of an overhead mixer in 29.97 g MMA. This gives a homogeneous, whitish, storage-stable dispersion.
- 1 part of this dispersion is mixed with 2 parts of a solution of 0.1 wt.% AIBN and 2 wt.% Dodecanethiol in MMA, degassed, filled into a test tube and polymerized under argon at 50- 70 0 C in a water bath. After completion of the polymerization and annealing, the test tube is smashed. This gives a transparent molding with a weak blue cast in the form of the test tube. If the beam of a laser pointer (650 nm) is allowed to enter the molded article from below (the bottom of the molded test tube), a sharp light beam is observed which very nicely visualizes the total reflection and the light conduction in this rod-shaped plastic glass body. The laser beam is attenuated imperceptibly even after a path length of 5 cm.
- a laser pointer 650 nm
- This dispersion is added to a solution of 0.5 g of AIBN, 1.5 g of t-butyl peroxybenzoate and 8.0 g of dodecanethiol in 170 g of MMA.
- the resulting mixture is filled in a polymerization, degassed for 10 min and polymerized in a water bath at 50 - 60 0 C. It is then annealed at 110 0 C and finally ground in a mill.
- Example 5 Manufacture of a molded article according to the invention by injection molding
- 1 part of the plastic particle masterbatch regrind according to Example 4 is mixed with 40 parts of ground material of a PMMA injection molding compound, eg Altuglas V920 CLEAR 100, and sprayed in an injection molding machine. In this way one receives injection molded parts: 6mm thick semicircles (radius: 30mm). These semicircles are transparent with a slight blue cast. If the light of a red laser (650nm) perpendicular to the surface of the circle is allowed to enter these platelets on the circular side over the edge, then you can follow the course of this light beam and observe the exit of the light beam or its reflection quite simply on the straight side and estimate the angle of total reflection.
- a red laser 650nm
