Definitions

  • the invention relates to a device for applying a viscous coating composition, in particular a paint or an adhesive, with the features of the preamble of claim 1.
  • the device is therefore preferably an application tool for a painter or plasterer who finds use in the construction sector. Further preferably, the device is a paint roller.
  • the invention relates to a method for producing such a device.
  • Paint rollers are well known in the art. They are used for the large-scale application of a paint on an on-site substrate, such as a wall or ceiling. For this purpose, the paint roller is immersed in a container with the paint to be applied, stripped off a grid and attached to the substrate in order subsequently to apply the paint to the substrate by rolling it off.
  • the paint roller is therefore suitable only for applying rollable viscous coating compositions, which need not necessarily be a color.
  • the viscous composition may also be a paste or adhesive that is rollable.
  • a paint roller In the production of a paint roller is usually a roller made of plastic covered with a plush or fur covering. The coating can be spirally wound or pulled up like a tube. Corresponding examples are in the German Utility Model DE 1 940 459 U1 called.
  • a paint roller is known with a foaming paint roller that is covered with a well-absorbent and a good-wicking material, such as nylon or nylon plush, lambskin, or the like.
  • the elastically flexible outer surface of the inking roller made of foam should facilitate the application of paint on uneven surfaces.
  • viscous coating compositions such as paints are usually pot-preserved, ie chemical preservatives are added.
  • chemical preservatives are added.
  • the preservation of pots, however, can be too strong Bacterial entry fail.
  • chemical preservatives are often undesirable.
  • the present invention is therefore based on the object of providing a device for applying a viscous coating composition, in particular a paint or an adhesive, which can be used repeatedly and, if used repeatedly, prevents or at least counteracts carry-over of microorganisms.
  • the device should be particularly suitable for applying a viscous coating composition that does not contain chemical preservatives.
  • the device proposed for applying a viscous coating composition comprises a rotatably mounted roller, which carries on the outer circumference an absorbent covering of fur, plush, foam or the like.
  • the covering for antimicrobial equipment contains silver or a silver compound.
  • Silver has a bacteriostatic or even a bactericidal effect, which is due to soluble or dissolved silver ions. Whether the silver ions merely inhibit the growth of the bacteria or kill the bacteria depends in particular on the concentration of the silver ions.
  • a solvent is required. This may be water, for example, to clean the device or a viscous coating composition with which the device comes into contact.
  • the bacteriostatic or bactericidal action of the silver contained in the coating or of the silver compound contained in the coating is thus particularly significant if it is to prevent bacterial attack of the device and / or the viscous coating composition.
  • the bacteriostatic or bactericidal action of the silver or the silver compound is permanent. This means that it will neither wear out nor degrade. In this way, a long-lasting protection of the device against bacterial attack can be achieved. As a result, repeated use of the device does not lead to carryover of the bacteria into a viscous coating composition to be applied. Further, by using a device according to the invention, the durability of a viscous coating composition can be prolonged.
  • the coating of the device has a coating containing silver or a silver compound.
  • a conventional coating such as plush, fur or foam, can be used, which is only later equipped by a coating antimicrobial.
  • the coating containing silver or a silver compound can be applied over the entire surface or partially, for example in the form of a pattern.
  • the coating may, for example, be a finish doped with silver or a silver compound.
  • the incorporation of the silver or the silver compound in the coating on the finish can be particularly easily realized.
  • the silver content in a coating or finish is preferably 0.01% by weight to 1.0% by weight, preferably 0.02% by weight to 0.6% by weight, and furthermore preferably 0.03 wt .-% to 0.5 wt .-%, each based on the total weight of the solids content of the coating or finish.
  • the finish in particular, a composition based on an organic polymer dispersion is suitable. Because this can form an elastic binder matrix, in which the silver components are permanently stored.
  • the finish contains an organic binder which has a glass transition temperature T g ⁇ 40 ° C., preferably T g ⁇ 30 ° C., furthermore preferably T g ⁇ 20 ° C.
  • T g ⁇ 40 ° C. preferably T g ⁇ 30 ° C.
  • T g ⁇ 20 ° C ethylene-vinyl acetate copolymer is used as a binder.
  • the finish is applied to the back of the pad. Because then the finish can be used in addition to the connection of the lining with the roller, for example by fusing or gluing.
  • the backside dressing may also be used to permanently bond fibers and / or threads of the fabric to a woven spine.
  • the backside of the covering is the ideal place of action for the silver ions. Because the surface is moistened, the moisture drips into the depth, that is, into the area of the back of the weave, as long as the covering is a fabric. In the depth of the moisture is the longest, so that the risk of bacterial attack is greatest here.
  • the covering comprises threads, fibers or hair
  • these may-alternatively or additionally-be doped and / or coated with silver or a silver compound.
  • the doping and / or coating can in turn be carried out partially, so that in this case the coating also has undoped or uncoated threads, fibers or hair.
  • silver threads can be incorporated into the covering.
  • the covering can be worked through with silver threads.
  • About the density of incorporated into the covering silver threads can then be adjusted in a simple manner, the antibacterial effect.
  • the silver or the silver compound is introduced into the coating via a coating and / or finish, the silver or silver compound is preferably in extremely finely divided form.
  • the more finely divided the silver or the silver compound the larger the surface over which bacteriostatic or bactericidal silver ions can be released. This means that the effect can be enhanced.
  • Nanoscale silver or a nanoscale silver compound is therefore particularly preferably contained in the coating.
  • the roller of the device according to the invention is rotatably mounted on a support bracket.
  • the mounting bracket facilitates the handling of the device. This is especially true when the mounting bracket is angled several times and / or equipped with a handle.
  • the rotatable mounting of the roller via at least one substantially disc-shaped cover part, which is rotatably mounted on the support bracket.
  • the cover part is arranged frontally with respect to the hollow cylindrical roller 1 to close it.
  • the cover part can be at least partially inserted or pressed into the roller.
  • a roller is provided on the outer circumference side with an absorbent covering of fur, plush, foam or the like.
  • a coating is used, the antimicrobial equipment silver or a silver compound contains.
  • the coating can be equipped both antimicrobial before joining with the roller as well as afterwards.
  • the coating may be provided at least partially with a coating containing silver or a silver compound before or after bonding to the roll.
  • the coating can be applied by dipping, dipping, spraying, spraying, printing or the like.
  • the coating is provided with a finish doped with silver or a silver compound prior to bonding to the roll.
  • a finish doped with silver or a silver compound prior to bonding to the roll.
  • the introduction of the silver or the silver compound into the coating by means of a finish can be accomplished particularly easily.
  • the finish is placed back.
  • the doped with silver or a silver compound finish can also be used to connect the pad with the roller.
  • the connection can be made by fusing or gluing by heating and softening the roller and / or the finish of the coating.
  • thermofusion process for bonding the lining to the roll.
  • the surface of a roller made of a plastic, such as polypropylene or polyethylene heated so that it melts.
  • the coating provided on the back with a finish is applied, which then connects to the surface of the roll via the finish.
  • a finish having thermoplastic properties is used, the bond is achieved not only via the fused surface of the roll but also through the finish. In this way, a very strong and thus permanent connection can be effected.
  • the silver-doped finish it is also possible to dope individual threads, fibers or hairs of the covering with silver or a silver compound.
  • the silver may or the silver compound may be incorporated into the yarn or threads or fibers.
  • individual threads, fibers or hairs of the covering can be coated with silver or a silver compound.
  • This form of antimicrobial equipment can also be made later, so that this method is particularly suitable for retrofitting already existing devices.
  • the coating can be applied, for example, by dipping or dipping. These procedures ensure that the coating reaches down to the depth of the coating.
  • silver threads can be incorporated into the covering.
  • the silver threads can be woven or acted when the covering is formed as a woven or knitted fabric.
  • nanoscale silver or a nanoscale silver compound to antimicrobialize the coating.
  • the finer the silver or silver compound the larger the surface over which bacteriostatic or bactericidal silver ions are releasable. This means that the effect is amplified.
  • the covering is preferably bonded to the roll, preferably further by fusion or gluing.
  • fusion or gluing reference may be made to the previously described methods, such as the thermofusion method.
  • FIG. 1 a device according to the invention in the form of a paint roller can be seen. To illustrate the invention, the paint roller is shown cut.
  • a cylindrical roller 1 In the region of the gate, a cylindrical roller 1 can be seen, which consists of a plastic tube and is coated with an absorbent coating 2.
  • the absorbent pad 2 consists of a plush material or faux fur, which is provided in the region of its We stipulatens 9 with a finish 4.
  • the finish 4 is used, inter alia, the attachment of the pad 2 to the roller. 1
  • finish 4 serves the antimicrobial finish of pad 2.
  • finish 4 has a silver content. Dissolved silver ions of the contained silver 3 under the action of moisture cause bacteria growth to be inhibited and / or existing bacteria to be killed.
  • the spine 9 of the pad 2 is the ideal site of action for antimicrobial equipment. Because when moistening the pad 2, the moisture penetrates into the depth of the plush material, from which it is difficult to escape again. The area of the web spine 9 thus holds the moisture the longest. Without the proposed antimicrobial finish, it would be an ideal breeding ground for microorganisms.
  • Fig. 1 can also be seen, the hollow cylindrical roller 1 is penetrated by a support bracket 7. On the mounting bracket 7, the roller 1 via a disc-shaped cover part 8, which is inserted at the front end into the roller 1, rotatably mounted.
  • Fig. 2 is a schematic cross section through a roller 1 of another preferred embodiment of a device according to the invention can be seen.
  • This embodiment has with the Fig. 1 in common that the roller 1 is formed from a plastic tube, which is covered on the outer circumference with an absorbent pad 2 made of a plush material.
  • the plush material in turn has a woven spine 9 which is provided with a finish 4 containing silver 3.
  • a cohesive connection of the pad 2 with the roller 1 is made.
  • the finish 4 is doped with the silver 3 and applied to the spine 9 in such a way that it penetrates the spine 9 and at least partially surrounds the threads 5 of the plush connected to the spine 9.
  • the silver 3 contained in the finish 4 is present as nanoscale silver 3 in order to form the largest possible reactive surface from which bacteriostatic or bactericidal silver ions can be dissolved out.
  • the silver doping of the finish 4 has the advantage that the silver 3 can be applied in a simple manner with the finish 4.
  • the one in the Fig. 2 shown covering 2 threads 5, which are doped with silver 3. Furthermore, individual silver threads 6 are woven into the plush material. The silver-doped filaments 5 and the silver filaments 6 enhance the antimicrobial effect since a larger amount of silver 3 is introduced. In addition, the number of threads 5, 6 and / or the arrangement of the silver 3 can be optimally distributed.
  • Fig. 3 is an example of a weave pattern for producing a covering 2 of a device according to the invention can be seen.
  • Individual warp threads in this case the outer warp threads, are each formed by a silver thread 6.
  • the weft thread consists of the yarn material of the plush, ie this is a thread 5. If the tissue is separated in the middle, the silver threads 6 come to lie in the region of the weaving back 9, ie at the ideal site of action.
  • the covering 2 of a device according to the invention may also be made of a material other than plush. In this case the same applies analogously.
  • the covering 2 has no threads 5 but fibers or hair, these can be doped and / or coated correspondingly with silver 3. The same applies with respect to any coating or finish 4 formed on the back. If the covering 2 is made of a foam, it can be doped with silver 3 during manufacture or subsequently coated with silver 3.
