Description
Background technology
The present invention relates to a kind of method that is used to make coated profiled elastomer element, this profiled elastomer element has the substrate of being processed by elastomeric material.The present invention relates to a kind of profiled elastomer element as described in the preamble in addition according to claim 10.The present invention also relates to the use of the profiled elastomer element of making according to the use of profiled elastomer element of the present invention or according to method of the present invention at last.
Profiled elastomer element for example is used for making scrapes glue skin or sealing band.This scraping on the windscreen wiper that the glue skin for example is used in automobile.Other application of scraping the glue skin for example is a window-cleaning device, for example is used for cleaning panes in the family like them.
In order to make windscreen wiper firmly produce satisfied result down very little, fitness for purpose reduce be used as that windscreen wiper uses scrape the work of glue skin the time friction.Be well known that to scraping the glue skin for this reason and set for example equadag coating or sliding lacquer coat.
The coating that is used to reduce to rub generally includes the two-component system that is made up of adhesives and hardener of heat hardening.The system of this heat hardening for example comprises the polyester of hydroxyl (base) hydroxy functionalization, propylene polymerization body or urethane polymer and for example melamine, acetaldehyde or isocyanate hardener.In order to reduce the friction of coating surface, usually add graphite or molybdenum disulphide as solid lubricant.This is for example by US-B6, and 696,391 is open.
Alternatively, by in the prior art for example by US-B7,028,367 discloses to sneak at the elastomeric material that is used for scraping the glue skin and has been used to the additive that reduces to rub.Additive as suitable has been enumerated PTFE, graphite, boron nitride, fluoropolymer or fluorochemical additive.
The graphite that in coating, contains is that as the shortcoming of solid lubricant graphite granule reduces the bond strength of coating and reduces abrasion property thus.The ratio of graphite surpasses the critical coating volume concentration of coating in many cases, and this causes the coating binding power to hang down and causes it not have enough abrasive resistances thus.A high proportion of graphite is essential, so that reach the low frictional behavior of coating surface.
The poly-vinyl, polypropylene or the polytetrafluorethylepowder powder that are used to reduce the friction drag of coating move to the surface of coating, realize thus its lubricated effect.Lacking the adhesiveness powder but shortcoming is separates from coating surface easily.
Also can use in addition and have low-melting wax as lubricant.Wax is being transferred on the surface of coating during the coating heat curing.When forming a thin surface of being rich in wax on the coating after the coating cooling.Reduce to scrape the friction of glue skin thus.But shortcoming is, low-melting wax is especially for example understood deliquescing when wax is in sunshine under in thermal environment, thus friction drag but also resistance to abrasion variation all not only.Especially low-melting wax can stick on the Windshield when windscreen wiper moves in this case.Have dystectic wax on the contrary and have advantage, even i.e. its also not deliquescing under solar radiation.But shortcoming is dystectic wax does not form continuous films at coating surface.
Disclosure of an invention
A kind ofly be used to make method and may further comprise the steps with profiled elastomer element substrate, coated of processing by elastomeric material according to of the present invention:
(a) coating material is applied in the substrate of being processed by elastomeric material, wherein coating material contains the lubricant of polymeric material,
(b) substrate that will be furnished with coating material is heated to above the fusion temperature that is included in the polymeric material in the lubricant, wherein on the surface of profiled elastomer element, forms polymer film,
(c) radiation profiled elastomer element is so that the polymer film sclerosis.
Through with the coating material coated substrate that contains lubricant, realize the good frictional behavior of profiled elastomer element.Improved the abrasive resistance of coating through sclerosis cure polymer film.
Profiled elastomer element for example can be the profiled member of that extrude, preesure-poured or mold pressing.
In a kind of form of implementation, the polymeric material that in lubricant, contains plays a part lubricant.Usually polymeric material is included in the adhesives.What be applicable to adhesives for example has polyacrylates, polyurethane, polyester-polyurethane, polyether polyurethane, polyester, polyamide, a polyamide-imides.
In second embodiment, lubricant contains solid lubricant, and it appears with the form of particle, and these particles apply with polymeric material at least in part.
Substrate through in step (b), being provided with coating material is heated to the fusion temperature above polymeric material, and polymeric material moves on the coating surface and fusing there.On the surface of coating material, form the film that constitutes by polymeric material thus.Through cure polymer film in step (c), form a solid-state surface thus, it has better wearing character under the same frictional behavior situation of improving.If lubricant contains solid lubricant, this solid lubricant remains in the coating through the cured polymer film so.Avoided this solid lubricant and from coating, discharged owing to wear and tear.
In a kind of form of implementation of the present invention, the polymeric material that is included in the coating material is to have low-melting wax.Have low-melting wax and have such characteristic, promptly it is tending towards spreading on the surface in coating under the temperature that is improving during the coating material age hardness.But have that low-melting wax can't sufficiently reduce friction coefficient and abrasion test is also very little in addition owing to adopt, therefore to need the processing should the surface, so that reach the characteristic of hope.This is achieved in that low-melting wax of deposition is cured through radiation from the teeth outwards.Formation has dystectic wax thus, and it has better frictional behavior and also has better wearing character in addition.
The suitable wax that is included in the coating material for example is paraffin, babassu (Carnauba) wax, ceresine wax or Fei She-Te Luoshi (Fischer-Tropsch) wax.
In a kind of alternative embodiment, polymeric material be selected from poly-vinyl (LDPE, LLDPE, HDPE), polypropylene, polytetrafluoroethylene, polyamide and PTFE modified polyethylene.

The accompanying drawing summary
Embodiments of the invention are shown in the drawings and in following explanation, describe in detail.
Shown in the accompanying drawing:
Fig. 1 is the viewgraph of cross-section with profiled elastomer element of coating,
Fig. 2 is the scheme drawing that is used to make the method for coated profiled elastomer element.
The working of an invention mode
The profiled elastomer element that is configured to according to the present invention shown in Fig. 1 with coating.
That be configured to according to the present invention, coated profiled elastomer element 1 comprises substrate 3.Substrate 3 generally is a profiled member, and it is through expressing technique, extrusion process or mould pressing process manufacturing.Substrate 3 is made with elastomeric material usually.As previously mentioned, the elastomeric material that is suitable as substrate 3 for example has NR, CR, EPTM, EPM or their compound.If what substrate 3 was used to windscreen wiper scrapes the glue skin, hope so to reduce as scraping glue skin profiled elastomer element 1 that use, coated and using the friction coefficient between the glass of windscreen wiper above that.Lower friction coefficient for example makes that running noises reduces.Realize this lower friction coefficient according to the present invention through in substrate 3, applying coating 5.According to the present invention, coating 5 contains polymeric material, and it forms polymer film on the surface of coating 5 when coating 5 sclerosis.In order to meet the requirements of frictional behavior and wearing character, the polymer film sclerosis is solidified through radiation profiled elastomer element 1.
Cross-sectional plane at the coated profiled elastomer element 1 shown in Fig. 1 has shown that two are scraped the glue skin, and they at first manufacture profiled elastomer element 1.In order to make single windscreen wiper, need profiled elastomer element 1 be opened along its center line in 7 minutes.Produce two single glue skins of scraping by profiled elastomer element 1.Alternatively,, also can make profiled elastomer element 1 separately earlier, then apply then at center line 7 places except to comprising that two profiled elastomer elements of scraping the glue skin apply.
Schematically illustrate the method that is used to make the profiled elastomer element that is configured to according to the present invention among Fig. 2.
Be applied in the substrate 3 at first step floating coat material 11.Coating material 11 contains lubricant 13, perhaps contains polymeric material.Lubricant 13 preferably is dispersed in the adhesives.Lubricant 13 preferably appears with the short grained form that is distributed in the adhesives in the case.
The adhesives that is suitable as coating material can be the known every kind of adhesives that is used to coating arbitrarily of professional.But be noted that adhesives will adhere on the elastomeric material of substrate 3 this moment, makes coating 5 can not throw off from substrate 3.Adhesiveness also can be improved through in coating material, adding adhesion enhancer.Alternatively also can be earlier attach agent and be applied in the substrate 3 increasing.Suitable increase that to attach agent for example be chlorinating poly-mer in organic solvent.
What be suitable as adhesives especially is polyacrylic resin, polyurethane resin, polyester-polyurethane base ethyl formate resin, polyethers-polyurethane resin, alkide resin, amilan, polyamide-imide resin.These resins can be crosslinked, and for example with methylated imino group melamine-aminoplast crosslinking agent, isocyanate crosslinking agent or epoxy crosslinking agent are crosslinked.
The polymeric material that in lubricant 13, contains for example is wax or polyolefin.Polytetrafluoroethylene or can also be fit to by crosslinked polyamide in addition.Especially polytetrafluoroethylene and crosslinkable polyamide also can be simultaneously use as the lubricant of lubricant.But lubricant 13 is a kind of solid lubricants in one embodiment.For example use graphite or molybdenum sulfide as solid lubricant.
Coating material 11 is by age hardness after on the elastomeric material that coating material 11 is coated to substrate 3.This age hardness is generally realized through the input heat.Lubricant 13 particles that are dispersed in the coating material 11 through heating coating material 11 rise on the surface of coating material 11.Form ground floor 15 thus, it is positioned in the substrate 3 and contains the adhesives of coating material 11 basically.On ground floor 15, form the second layer 17, it contains lubricant 13 basically.In substrate 3, form surface like this with low friction coefficient.
The second layer 17 forms through the moving on the surface of coating of particle of lubricant 13; The lubricant particle that is contained; For example graphite granule, molybdenum sulfide particle; After adhesives sclerosis,, windscreen wiper can also from this second layer, discharge when move, because be not enough greatly at the polymeric material and the adhesive force between the lubricant particle of the formation second layer.Also possible is that the second layer 17 removes owing to windscreen wiper moves on windshield with being worn.Especially when the polymeric material that uses be this situation when being soft, when soft wax layer, be this situation for example.Especially it has low softening point to the characteristic of soft wax layer, and wax is worn easily and removes and transfer on the windshield thus.
In order the second layer 17 to be stablized and lubricant to be remained in the second layer 17, therefore according to radiation coating 17 of the present invention, so that the second layer 17 age hardness.Radiation to the second layer 17 is for example implemented through electron irradiation or gamma radiation.Coating 5 is placed under the effect of radiation appliance 19, radiation 21 is gone out to be transmitted on the coating 5 by this radiation appliance for this reason.Not only electron irradiation but also gamma radiation all are suitable for carrying out radiation.
Using electron irradiation to come between the polymer molecule that contains therein on the surface of the second layer 17, to form associative key under radiation coating 5 situation, polymer molecule is crosslinked thus.The polymeric material that in the second layer 17, contains is hardened and is formed the layer 23 that hardens.Make the surface-stable of coated profiled elastomer element 1 through the sclerosis of the second layer 17.Polymeric material no longer can easily wear away thus.The particle of this external lubricant is remained in the layer 23 of sclerosis better.These particles no longer can easily discharge.So also improved the lubricating effect of coated profiled elastomer element 1 and friction coefficient is reduced lastingly.
Different with electron irradiation, gamma radiation deeper is penetrated in the second layer 17.The layer 23 of sclerosis is than when hardening through the radiation 21 of adopting electron irradiation, having bigger thickness.
Owing to adopt electron irradiation or the gamma radiation second layer 17 that hardens to form the layer 23 of sclerosis, therefore suitable is that contain and form the polymeric material of the second layer 17, all polymeric materials that can harden through the radiation of adopting electron irradiation or gamma radiation at lubricant 13 as polymeric material.Suitable polymers is polyolefin especially, polypropylene (PP) for example, poly-vinyl (HDPE, LDPE, LLDPE) and other polymeric material for example polytetrafluoroethylene (PTFE) and crosslinkable polyamide.Because therefore the especially latter's yet super fatting agent effect simultaneously need not use additional solid lubricant, like graphite or molybdenum sulfide under use polytetrafluoroethylene or crosslinkable polyamide situation.
Owing to the friction coefficient of profiled elastomer element 1 is reduced through finish coat; Therefore profiled elastomer element can use in all that this profiled elastomer element 1 is guided on another surface in the localities; This situation is as for example being on the windscreen wiper of automobile or under the situation at window-cleaning device, when for example this window-cleaning device uses in the family.
