Definitions
- the invention relates to a lubricating varnish component, a lubricating varnish produced therewith, and a method for coating elastomers, in particular elastomer profiles such as windshield wiper blades, with this lubricating varnish according to the preamble of the independent claims.
- wiper blades With windshield wiper blades, it is important that they can adapt as well as possible to the contour of the windshield of a motor vehicle and that they remain flexible even at different temperatures. Therefore, wiper blades are usually made from elastomer profiles, mainly rubber materials such as natural rubber or chloroprene rubber are used. In addition, wiper blades made of silicone rubber or polyurethane rubber are also known.
- elastomers Compared to materials such as glass or plastic, elastomers have high sliding friction coefficients, so that with a defined vertical contact force of an elastomer profile in the form of a wiper blade on the surface of a glass pane, a multiple of the contact force often has to be used for horizontal movement. If the windshield wiper is operated when it is wet, this is not a major problem, since the water film on the windshield creates a thin lubricating film between the windshield wipers. sheet and the disc is formed so that a hydrodynamic lubrication is established. However, problems arise when the wiper blade is operated as a lubricating film without water, for example in summer or after brief rain showers. Under such conditions, the windscreen dries quickly, causing the coefficient of friction to rise sharply, which can lead to squeaking, rattling or even stoppage of the windshield wiper.
- DE 38 39 937 AI discloses a one-component polyurethane lacquer for coating elastomers, which contains reactive polysiloxanes.
- EP 293 084 AI describes a coating which, in addition to a polyurethane and a siloxane, also contains an additive such as carbon black, Teflon, graphite or talc. This material can be used to produce coatings on elastomers that have a low coefficient of friction under dry conditions.
- the lubricating varnish component according to the invention, the lubricating varnish according to the invention and the processes according to the invention for coating elastomers have the advantage over the prior art that a coating can be produced in particular on windshield wiper blades that has a particularly low dry friction coefficient, so that such wiper blades on dry or drying vehicle windows have particularly favorable properties.
- the coating according to the invention significantly reduces the force required to move the wiper arm over the window, so that the electric motor driving the wiper arm can also be made smaller. This also allows the use of cheaper engines and reduces energy consumption in the motor vehicle.
- the advantages mentioned are particularly noticeable in vehicle types in which large, flat panes are provided to reduce the air resistance and require very long wiper arms and wiper blades.
- the coating according to the invention on windshield wiper blades reduces unpleasant noises such as squeaking or rattling.
- Another advantage of the lubricating varnish according to the invention and the methods according to the invention is that a coating thus produced on a windshield wiper blade ensures a consistently good wiping quality over a longer period of time, in particular in accordance with the time between the normal inspection intervals of a motor vehicle.
- the lubricating varnish according to the invention shows a very good adhesion and abrasion resistance on elastomer profiles.
- the methods according to the invention have the advantage that the applied lubricating varnish can be applied reliably with constant quality and simple process technology.
- the lubricating varnish according to the invention is significantly more environmentally friendly.
- the lubricating varnish according to the invention is in the form of an aqueous 1-component or 2-component varnish which does not pose a risk to the environment. This reduces process costs and simplifies storage.
- lubricating varnish can be applied in a variety of ways, for example by spraying, dipping or brushing.
- the coating is advantageously applied to the elastomers before they are vulcanized, so that the energy supplied during the vulcanization can be used simultaneously for curing and / or thermal crosslinking, and the lubricating lacquer also hardens in a very short time. Furthermore, due to the higher reactivity of the unvulcanized material, better crosslinking of the coating with the elastomer forming the base is achieved in this case.
- the coating can also take place after vulcanization. This enables the coating to be to be applied outside the production line for the elastomer profiles.
- a hardener based on isocyanate has proven to be particularly advantageous as the hardener that can be added to the lubricating lacquer component.
- the invention is initially based on a paint for coating elastomers sold by Henkel KGaA, Dusseldorf under the brand name Sipiol®.
- This Sipiol® varnish which is a polyurethane system that contains reactive polysiloxanes, is especially suitable for coating rubber profiles.
- the polysiloxanes crosslink with the polyurethane system so that they form a component that lowers the coefficient of friction and is integrated into the polymer.
- it is initially available as an aqueous 1-component varnish or 2-component varnish, and also contains carbon black as an additive.
- the usual elastomer profiles for windshield wiper rubbers were first coated with a Sipiol ⁇ -based lubricant as part of a comparison test.
- the paint component Sipiol® WL 2000-21 which is sold by Henkel KGaA and which is present as a suspension containing soot, was mixed in a ratio of 100: 6 with the isocyanate-based hardener WV20, also sold by Henkel KGaA, according to the instructions.
- This lubricating varnish was then applied in the form of a coating to the elastomer profiles, which had previously been pretreated with a primer also sold by Henkel KGaA under the name Cuvertin® X8536 to improve adhesion.
- the Sipiol® WL 1000-21 paint system which was also sold by Henkel KGaA, was used, which is also available as a soot-containing suspension, but in contrast to the Sipiol® WL 2000-21 system, no hardener was added before coating must be, ie it is a 1-component system. Otherwise the procedure was as above.
- the results obtained with the hardener-free Sipiol® WL 1000-21 system were similar to those achieved with the hardener-added system Sipiol® WL 2000-21.
- polyamide powder, polyethylene powder or a solution of a polyamide is particularly suitable as additives.
- modified coating varnishes lead to very well adhering coatings on elastomer profiles with particularly low dry friction coefficients ⁇ dry of less than 1.5, sometimes less than 1.0, which are both abrasion-resistant and weather-resistant.
- ⁇ dry dry of less than 1.5, sometimes less than 1.0
- they show no transfer to the opposing body, ie the wiped glass. This is particularly important with windshields, in order not to leave an undesirable lubricating film that could impair the view.
- a polyamide powder with the smallest possible particle size of preferably less than 10 ⁇ m, in particular less than 5 ⁇ m is added to 10 ml of hard-free or hard-containing lacquer system.
- the suspension obtained was then stirred well and applied in the form of a coating to a still unvulcanized, extruded elastomer profile which was shaped as a wiper blade.
- the elastomer profile was pretreated with the primer Cuvertin® X8536, which is a solution of chlorinated polymers in organic solvents, to improve adhesion.
- the coating was applied to the elastomer profile by dipping.
- Sipiol® systems mentioned are, moreover, aqueous polyurethane-polysiloxane dispersions which also contain other additives. Further details on these known products from Henkel KGaA can be found in the corresponding data sheets.
- the solids content of the polyamide powder added in the lubricating varnish can reach up to 90 percent by weight, based on the finished lubricating varnish suspension. It is preferably less than 25% by weight, since at higher proportions the coating obtained sometimes does not remain elastic enough, i.e. the adhesion of the coating to the elastomer profile is reduced.
- a polyethylene powder is also suitable as a powdery additive to the lubricating varnish component or the lubricating varnish.
- Polyethylene powders with an ultra-high molecular weight have been found to be particularly advantageous, the particle size of the powder particles also being below 10 ⁇ m.
- 1.5 g of polyethylene was added to 10 ml of the mixture using one of the Sipiol® coating systems, ie Sipiol® WL 2000-21 with the described hardener WV 20 or Sipiol® WL 1000-21 without hardener.
- Ultra high molecular weight powder added. For example, this is suitable under the name PE-UHMW Hostalen® GUR 2126 polyethylene powder sold by Ticona, Oberhausen.
- polyethylene powder is a very suitable dry lubricant or additive to the lubricating varnish in order to obtain coatings on windshield wipers with very low dry friction coefficients.
- a third exemplary embodiment is again based on one of the Sipiol® coating systems already described according to the first or second exemplary embodiment. Furthermore, an alcoholic or aqueous solution of a polyamide is added to this lacquer, the polyamide contained therein acting as an additive that reduces dry friction compared to glass, which, when added in dissolved form, has a very fine distribution in the basic system or matrix system with polyurethane and siloxane having. In particular, this ensures that sufficient polyamide is available as dry lubricant throughout the coating.
- soluble polyamides for example, all alcohol-soluble polyamides or copolyamides can be used.
- the use of an N-methoxymethylated polyamide has proven to be particularly advantageous.
- a compound which catalyzes the crosslinking of the dissolved additive polyamide is added to the lubricating varnish.
- An organic acid is particularly suitable for this.
- the cross-linked polyamide is created and the crosslinked polyurethane system, two interpenetrating, insoluble networks, wherein crosslinking of the polyamide with the polyurethane system can also occur.
- the mixture of Sipiol® coating system and hardener or hardener-free Sipiol® coating system has the task of ensuring the elastic properties of the coating obtained, while the polyamide component lowers the dry friction coefficient.
- first coat the elastomer profile with the unmodified Sipiol® coating system-hardener mixture or the hardener-free Sipiol® coating system, i.e. without coating the polyamide additive, and then applying a further, second coating with the polyamide dissolved in alcohol to this first coating before subsequent curing.
- the application of the second coating can be carried out both on the already air-dried first coating or wet-on-wet, i.e. on the still wet first coating.
- This procedure with two successively applied coatings has the advantage that the first coating primarily imparts improved adhesion to the elastomer profile, while the second coating primarily reduces the dry friction of the elastomer profile or the wiper blade compared to glass.
- the additive or generally the wiping behavior of the elastomer profile can be adapted to the type of window to be wiped.
- the Sipiol® hardener mixture or alternatively, the hardener-free Sipiol® system is mixed again according to the instructions and first diluted with 30% water in order to reduce the thickness of the coating obtained in the following compared to the exemplary embodiments with powdery additive.
- This lubricating varnish was then applied to a prepared elastomer profile and dried in air at 25 ° C until no more damp spots were visible.
- a 5% to 10% solution of a polyamide in an ethanol-water mixture for example a solution of the polyamide Ultramid® IC, which is sold by BASF AG, Ludwigshafen, was then applied to this first coating in the form of a second Coating applied.
- the elastomer profile coated in this way was then dried and cut at 90 ° C. to 120 ° C. for 15 minutes, and then, as above, the dry friction coefficient on glass was determined. This resulted in values from 0.8 to 1.2. This coating also showed no detachment and very good adhesion after extensive longitudinal expansion.
- a last exemplary embodiment provides for one of the Sipiol® basic systems to be applied to an elastomer profile in the form of a coating first without an additive, ie without adding a polyamide powder, a polyethylene powder or a solution of a polyamide, and only after that on the still wet coating to apply a fine polyamide powder or a fine polyethylene powder, in particular a fine polyethylene powder with ultra-high molecular weight.
- the powder is sprinkled or inflated onto the still wet coating, for example, and then the coating sprinkled or blown with the powder is dried at 120 ° C. for 15 minutes. Subsequent measurements of the dry friction values of coated windshield wiper blades produced in this way gave dry friction values of 0.6 to 0.9.
- the elastomer profiles are generally produced with the aid of an extruder, the coatings according to the illustrated exemplary embodiments preferably being carried out immediately thereafter extrusion by spraying, dipping or brushing.
- a customary vulcanization process of the elastomer profiles then takes place, for example in a salt bath or in an oven, before the coated and vulcanized elastomer profile is finally cut.
- the coating can also be applied to the elastomer profile only after vulcanization, which, however, requires a further temperature treatment, preferably at a lower temperature, than in the preceding vulcanization. This temperature treatment then takes place for example behind the salt bath or behind the oven in another heating zone.
- the temperature treatment during vulcanization or in the downstream heat zone brings about a chemical crosslinking within the coating and also a connection or crosslinking of the coating with the elastomer profile underneath.
