Definitions
- the invention relates to a method for producing a component from a glass / plastic mixture.
- the invention further relates to the use of the component produced by the method.
- plastic materials especially based on thermoplastics.
- a filler is added to the plastic material to improve the mechanical and thermal properties.
- thermoplastic used as the thermoplastic.
- the glass is added in the form of glass fibers (glass fiber reinforced plastics).
- the glass fibers are embedded in the plastic.
- Solder bath resistance is increasingly required for the components. This is the only way that the components are suitable for surface mounting (SMT). Therefore, high-temperature thermoplastics are preferably used as the thermoplastic.
- the injection molding technology used to manufacture the components means that the glass fibers are partially printed on the surface or even protrude from it. These glass fibers protruding from the surface can tear off during mechanical operation of the component or
- the liquid-crystalline polymers (LCP) with 30% by weight glass fibers which are preferably used as high-temperature thermoplastic, have a further disadvantage. Due to their LCP-typical layer structure, which is particularly evident in injection molded parts, the components made with LCP have poor tribological properties. When these components are used, the disadvantages mentioned are avoided by using an external lubricant. The disadvantage of an external lubricant is that it is consumed over time and that it in turn can lead to contamination of electrical contacts.
- the aim of the present invention is therefore to provide a method for producing a component from a glass / plastic mixture which has little abrasion.
- the invention provides a method for producing a
- Component made of a glass / plastic mixture in which a mixture of a thermoplastic with a processing temperature Tl and first glass particles with saturated bonds on the surface is assumed. Another property of the first glass particles is that they have a glass transition temperature T2 ⁇ T1. The component is formed at a temperature T3> T1, which causes the first glass particles to melt. The melted first glass particles create second glass particles with saturable bonds on the surface. The saturable bonds on the surface of the second glass particles are saturated by attachment to the thermoplastic.
- the method according to the invention for producing a component from a glass / plastic mixture with glass particles which, for example, have bonds saturated on the surface due to storage in air and which are reacted by the low glass temperature m new particles with saturable bonds on the surface very good adhesion of the glass particles to the plastic matrix achieved.
- exposed glass particles or glass particle ends on the surface of the component are avoided, as a result of which they produce only extremely little abrasion with mechanical friction.
- This reduced abrasion has the further advantage that no special measures have to be taken to keep the air clean, for example to filter out glass fibers or glass fiber particles.
- there are cost savings for machines and tools since wear is drastically reduced compared to the known glass fiber reinforced materials.
- the glass melt differs from the solidified glass also in the nature of its surface. While the active polar end groups of a solidified glass e.g. Saturate with hydroxyl groups of the water that is always present in the ambient air and thus lose their activity, there are still free and active end groups in the glass melt that, when in contact with e.g. Metal or plastic with which the metal and / or plastic surface interact and thereby bring about good wetting and / or adhesion to them.

- there are still free and active end groups in the glass melt that, when in contact with e.g. Metal or plastic with which the metal and / or plastic surface interact and thereby bring about good wetting and / or adhesion to them.
- a glass / plastic mixture which contains: - as glass, particles of a low-melting sulfophosphate glass of the following composition, given m mol%:
- a “low-melting point” sulfophosphate glass is understood to be a glass with a low glass temperature T2, in particular a glass with T2 ⁇ 300 ° C.
- the glass temperature is to be understood as the temperature at which the glass softens and thereby becomes flowable.
- a "high-performance thermoplastic is a high-performance plastic (" high-performance polymer *), in this case a high-temperature-resistant plastic ("heat-resistant polymer *," high-temperature resistant polymer ⁇ ).
- the processing temperature Tl of the plastic is at least 300 ° C, since this is the only way to ensure the solder bath resistance of the components made from it.
- the glass temperature T2 is below the processing temperature Tl, which means that the glass is in a flowable state. As a result, the glass / plastic mixture shows very good flow properties for the production of thin-walled components or components with a complicated geometry.
- the glass / plastic mixtures according to the invention have good mechanical and thermal properties and good processing properties, in particular good flowability, even with high filler, i.e. high glass content. They are also distinguished by an excellent chemical resistance, in particular to water, acids and bases, and surprisingly without the addition of stabilizers.
- the glass / plastic mixtures also have excellent abrasion resistance, and material recycling is possible without any problems because the glass component is not shortened, as is the case with glass fiber reinforced mixtures.
- the glass / plastic mixtures according to the invention preferably have a glass with a glass transition temperature of 250 ° C ⁇ T2 ⁇ 280 ° C.
- the mixtures preferably find a sul- fophosphate glass of the following composition use: 4.9% L 2 0, 9.4% Na 2 0, 7.1% K 2 0, 1, 6% CaO, 36.6% ZnO, 20.0% P 2 0 5 and 20.4% S0 3 .
- This glass has a glass temperature T2 of 268 ° C.
- a high-performance thermoplastic is advantageously a polyether ether ketone (PEEK), a polyether imide (PEI), a polyphenylene sulfide (PPS), a partially aromatic polyamide, such as polyphthalate (PPA), or a liquid polymer (LCP).
- PEEK polyether ether ketone
- PEI polyether imide
- PPS polyphenylene sulfide
- PPA polyphthalate
- LCP liquid polymer
- Other high-performance thermoplastics that can be used are polyaryl ether ketones (PAEK) in general, for example polyether ketones (PEK), and polysulfones (PSU), in particular polyether sulfones (PES) and polyphenylene sulfones (PPSU).
- PAEK polyaryl ether ketones
- PSU polysulfones
- PSU polyether sulfones
- PPSU polyphenylene sulfones
- the proportion of the glass component, i.e. of the sulfophosphate glass on the glass / plastic mixture is preferably 15 to 60% by weight.
- the glass content can be up to 80% by weight.
- the mixtures can also contain conventional additives, such as color pigments and stabilizers. Possible applications include sensors, actuators, connectors, electro-optical components and relays.
- the components produced using the method according to the invention can be used particularly advantageously in arrangements in which they interact with other components while exerting mechanical friction.
- it is considered to use the components produced with the method according to the invention in electromechanical switches. This is where the low-abrasion behavior comes into play Wear, as contamination of the electrical contacts can be largely avoided.
- the reduced friction reduces the energy consumption when operating the component and extends the service life of the component.
- the figure shows a component produced with the method according to the invention with a second component in a schematic cross section.
- the figure shows a first component 1 produced using the method according to the invention, which is arranged above a second component 2.
- a force F acts on the first component 1 and presses it against the second component 2.
- the first component 1 moves transversely to the second component 2, as indicated by the double arrow.
- the first component 1 can be produced, for example, by an injection molding process.
- the injection molding process has the advantage that a large number of components of almost any shape can be produced simultaneously in large numbers.
- the invention is not limited to the exemplary embodiment shown, but is defined in its most general form by claim 1.
