Definitions
- the present invention relates to transparent Plastic discs made of acrylic glass with threads inside made of plastic, which arises in the event of a break Largely hold fragments together, procedure for Manufacture of such transparent plastic panes as well the use of the plastic discs mentioned.
- the invention relates to transparent Plastic washers, which in the event of breakage of the Plastic disc essentially no splinters or loose Fragments result, the plastic washers such Type are particularly suitable for noise barriers.
- EP 0 531 982 also discloses transparent ones Plastic discs with plastic threads inside, the in the event of a breakage, fragments largely formed stick together, with those disclosed in said EP Discs have embedded threads that are high in contrast are and so the protection in a particularly aesthetic way can serve in front of birds.
- the object of the present invention based on a transparent plastic pane made of acrylic glass with internal threads made of plastic, which in continuous use under usual conditions, for example when used as a noise barrier, one has an excellent homogeneous optical impression.
- the present was Invention based on the task, a simple and inexpensive to find a practicable process that involves the manufacture of transparent plastic panes made of acrylic glass with inside lying plastic threads allowed, the Matrix adhesion of the embedded threads should be so great that the fragments, which in the event of breakage of the Disk can occur, secured without it continuous use under normal use, for example as a noise barrier, to an undesirable The threads come off.
- Preferred embodiments are the subject of independent claim 1 dependent dependent Product claims.
- the transparent plastic panes made of acrylic glass according to the invention is known per se to the person skilled in the art.
- Typical Slice thicknesses are 4 to 40 mm, 12 are preferred up to 25 mm.
- the slices are usually one size Made from 1.5 m x 1 m to 2 m x 3 m, for special Applications are also larger or smaller versions possible.
- the panes are usually largely clear transparent, preferably colorless or easy, e.g. B. smoke brown, tinted.
- the colorless, crystal clear clear plastic panes usually have one Transmittance of at least 70%, one is advantageous Transmission from 90 to 95%.
- the embedded threads are made of plastic usually from one with the polymer matrix Acrylic glass incompatible plastic, for example polyamide threads or polypropylene threads are suitable. Monofilament threads are preferred. H. Monofilaments.
- the threads usually run in the plastic disc horizontal, since the panes are clamped laterally; the cohesion in the event of a break is special Cheap. As a rule, the threads are parallel to each other relocated. If desired or necessary, two Layers of threads are inserted into the disc, which then preferably run in two directions, one angle of 90 ° between threads of different layers in particular is advantageous. Such a design looks from the outside viewed from like a mesh fabric.
- the threads in this way embed that at least one of the embedded threads a maximum deflection of 1 mm or more by one the ends of the thread has an imaginary straight line.
- the the sagging positioning of the Plastic threads in the acrylic glass matrix under certain circumstances lead to more advantageous behavior of the panels suitable as noise barriers at the relevant Tests as the specialist from the relevant standards are known.
- the plates according to the invention are characterized in that that the embedded plastic threads at least partially are arbitrated. This means either all Plastic threads can be fully sized it but can also only some of the plastic threads, which in embedded in a plate, to be arbitrated even partially.
- the internal threads are sized in sections. That is, a thread is at certain intervals, the preferably 0.5 to 1.5 m, particularly preferably about 1 m, over a certain length of about 2 to 10 cm arbitrated.
- a thread is at certain intervals, the preferably 0.5 to 1.5 m, particularly preferably about 1 m, over a certain length of about 2 to 10 cm arbitrated.
- AB system of section-sized thread will make it possible to Matrix adhesion of the embedded thread to the surrounding one Acrylic glass matrix to vary optimally and on all to coordinate conceivable requirements. So with an AB system of a thread that has been finished in sections the main part of the thread, d. H. the vast length of a thread, loosely remain in the PMMA matrix, what in particular, the functionality is guaranteed and yet can fix the Thread optimally reached in the sized areas become. A replacement of the thread by the usual Temperature cycles during the day and night are therefore locked out.
- Sized threads show at least parts of them Surface the residues of a sizing agent.
- any known to those skilled in the art can be used here Sizing with appropriate sizing agents in question come.
- the plastic disc according to the invention in that the threads are the residues of a Have sizing agent, which is a dissolved Contains phenol formaldehyde resin. It has been under the Invention shown that such a solution Formaldehyde resin particularly favorable concentration ranges for the finishing treatment and at the same time one high variability in setting the matrix adhesion of the brings with it plain threads.
- the invention also includes a method for Manufacture of a transparent plastic disc Acrylic glass with internal threads made of plastic, which in the In the event of a breakage, fragments largely arise stick together in which process the plastic threads be embedded in the acrylic glass, whereby the Process characterized in that the threads before the Embedding mediates.
- the thread detachment from the matrix which is responsible for can be the glimmer or glitter of the threads avoid with a finishing treatment.
- sizing agents generally come all means familiar to the expert for this purpose in Question. It is particularly preferred Sizing agent, the dissolved phenol formaldehyde resin exhibit.
- the threads are treated with a sizing agent which has approximately the following composition before being embedded in the acrylic glass matrix: phenol ⁇ 10% formaldehyde ⁇ 2% Methanol ⁇ 2% Ethanol ⁇ 30%
- the phenol formaldehyde mixture is acid catalyzed with Paratoluenesulfonic acid implemented and with the the sizing threads in a suitable manner then in contact brought.
- the threads can either completely, d. H. according to the full length, or can be contacted in sections with the size. After treating the threads with the size, the Dried threads and then in the usual way in the Acrylic glass matrix embedded.
- the adhesion of the sized threads to the matrix can increase be influenced in different ways. For one, it can Type of size can be varied. On the other hand, the Sizing treatment also concentrates the Sizing agent in the size to vary the liability can be set on the matrix. After all, you can Threads to be embedded completely or in sections Contact along the length with the size. It is also possible to use fully sized threads or partially sized threads, d. H. in sections sized threads, along with unsized threads in embed one and the same plastic disc.
- Phenol formaldehyde resin size has been found that a certain concentration range at the Sizing treatment is particularly cheap. If it is too high The matrix adhesion of the thread can determine the size become too large, so that attempts to destroy the transparent plastic panes according to the invention with embedded plastic threads for the appearance of free Fragments can come. When breaking the acrylic sheets the polyamide thread can tear because it is too strong Liability a stretch is no longer possible. Around Problems of size concentration (matrix liability) deal and still take advantage of fixing the Can ensure plastic thread in the plate for example the AB systems already mentioned above be used.
- the method according to the invention is made of plastic threads embedding in the matrix at a distance of 0.5 to 1.5 m in 2 to 10 cm in length treated with size so that after the Embedding of pre-treated threads of the main part of the thread remains loosely in the PMMA matrix, while the How it works, i. e. the fixation of the thread, nevertheless is achieved.
- Example 2 The procedure was as in Example 1, only with the Difference that the thread every 80 cm to a length of 5 cm was impregnated. The size concentration was here again 0.6%. This variant is advantageous because of the risk of overdosing The thread is not fixed in size the PMMA matrix is guaranteed and the mobility of the Thread is still present, so when Attempted destruction here also no free fragments occurred.
