Definitions
- the invention relates to an acrylic glass with photochromic properties, methods of preparation and uses.
- polymethyl methacrylate Due to its hardness as a plastic matrix, polymethyl methacrylate is not suitable for these dyes since it does not leave the necessary freedom of movement for the dye molecules.
- plasticizers or softening comonomers makes the system effective. However, the material becomes so soft that it no longer meets the requirements for the respective applications.
- the task was therefore to produce a polymethyl methacrylate with photochromic properties.
- the object was achieved by Poymethylmethacrylat sandwiches containing two polymethyl methacrylate plates and an intermediate layer containing photochromic dyes.
- PMMA polymethyl methacrylate
- photochromic properties can be produced by a sandwich construction.
- the two outer PMMA plates provide the mechanical stability, the soft intermediate layer allows the introduction of photochromic dyes.
- the outer PMMA sheets can be modified with the known additives.
- sunscreen agents can be incorporated.
- the PMMA plates may contain dyes which are UV light transmissive.
- the interlayer must be so soft that the dye molecules retain sufficient mobility to produce the color change by isomerism.
- plasticizers it is possible to use all commercial additives, such as adipates, phthalates, phosphates or citrates. Particular preference is given to adding di-n-butyl adipate and diisobutyl phthalate as plasticizer.
- PMMA compatible monomers can be used.
- Compounds of the class of acrylates or higher alkylated methacrylates are particularly suitable.
- the intermediate layer can also consist entirely of polyacrylates or higher alkylated polymethacrylates. It has been found that especially propyl, butyl and longer chain methacrylates are suitable.
- photochromic dyes can be introduced. Dyes from the group of spiro-naphthoxazines and naphthopyrans are preferably used. Particular preference is given to photochromic reversacol dyes from J. Robinson (Huddersfield, England), such as e.g. Gray 219, Gray 208, Gray 306, Gray 195, Brown 105, Flame 29 B, Sea Green 5, Velvet Blue, Sunflower, Graphite and Palatinate Purple.
- dyes are added to the plastic matrix as a function of the layer thickness.
- a small thickness requires a high concentration. So be For example, at a thickness of 3mm the dyes added in amounts of 0.001% to 0.3%. With low layer thicknesses, up to 10% of dyes can be added. It has been found that good photochromic properties are detectable when the thickness of the intermediate layer is between 0.01 and 5 mm. The best results were achieved with layer thicknesses between 0.1 and 3 mm. It is also possible to use mixtures of different dyes.
- the sandwiches according to the invention can be prepared by various processes. Particularly suitable is the chamber casting method.
- the polymethyl methacrylate plates are manufactured separately in the chamber casting process. Depending on the thickness of the plates, the temperature and time of tempering are determined.
- the conventional additives e.g. UV filters, initiators, dyes or stabilizers are added.
- the intermediate layer is coated with the appropriate additives, e.g. photochromic dyes and optionally plasticizers, cast between the polymethyl methacrylate plates.
- the composite is produced via source processes.
- the PMMA plates can be treated with crosslinkers to regulate the swelling.
- the internal coextrusion process is suitable for producing the sandwiches according to the invention.
- EP1270176 describes a process for the production of multilayer hollow profile sheets. Here, an upper and a lower layer of a plastic melt and an im Inner layer of the hollow chamber profile made of a plastic melt by way of coextrusion of the plastic melt and using an extrusion die and subsequent calibration of the extrudate obtained. With an adapted extrusion tool, the sandwiches according to the invention can be produced by this process.
- Part of the invention are thus also the chamber casting process and the internal coextrusion process for producing the sandwiches according to the invention.
- the poymethyl methacrylate sandwiches with photochromic dyes are versatile. They can be used, for example, for self-shading systems in the construction sector, such as e.g. Greenhouses, conservatories, glazings (e.g., skylights), shop windows.
- light stabilizers may be added to protect the photochromic inner layer.
- HALS products such as Tinuvin 770 and UV absorbers, which are particularly effective in the short-wave UV range, e.g.
- Example 2 The batch is stirred vigorously, filled into a 400 ⁇ 500 mm silicate glass chamber which has been distanced with a 3 mm thick cord and polymerized in a water bath at 45 ° C. for 16 h. The final polymerization is carried out in a tempering 4h at 115 0 C.
- Example 2 The final polymerization is carried out in a tempering 4h at 115 0 C.
- the mixture is intensively stirred, filled into a distanced with a 3mm thick cord chamber of colorless acrylic glass from test 1 and polymerized h at 50 0 C in a water bath 22nd
