Definitions
- the invention relates to a method for the antimicrobial finishing of surfaces by thermally assisted application of antimicrobial polymers.
- Mucus layers often form, which cause microbial populations to rise extremely, which have a lasting impact on the quality of water, beverages and food, and can even lead to product spoilage and consumer health damage.
- Bacteria must be kept away from all areas of life where hygiene is important. This affects textiles for direct body contact, especially for the genital area and for nursing and elderly care. In addition, bacteria must be kept away from furniture and device surfaces in care stations, in particular in the area of intensive care and the care of small children, in hospitals, in particular in rooms for medical interventions and in isolation stations for critical infections and in toilets.
- Plastic cladding are equipped, which are particularly easy to handle. Next to the Undesired visual impression can also be reduced under certain circumstances, the function of appropriate components. In this context, for example, algae growth of photovoltaic functional areas should be considered.
- the copolymer produced with aminomethacrylates is only a matrix or carrier substance for added microbicidal active substances which can diffuse or migrate from the carrier substance. Polymers of this type lose their effect more or less quickly when the necessary “minimal inhibitory concentration” (MIC) is no longer achieved.
- MIC minimum inhibitory concentration
- From European patent applications 0 862 858 it is also known that copolymers of tert-butylaminoethyl methacrylate, a methacrylic acid ester with a secondary amino function, have inherent microbicidal properties.
- systems based on novel compositions and improved effectiveness must also be developed in the future. The antimicrobial effectiveness of these polymeric systems is closely linked to their three-dimensional structure, conformation and available surface. It is therefore not enough to simply develop new effective systems in order to exploit the full potential. In addition, an optimization of the structure and available surface must be added.
- the present invention was therefore based on the object of developing a method for the antimicrobial finishing of surfaces which is simple to carry out and is virtually independent of the material of the surface to be treated.
- the systems thus optimized are intended to prevent the settlement and spread of bacteria, algae and fungi on surfaces even more effectively than the standard systems already available.
- antimicrobial polymers it is not necessary to incorporate antimicrobial polymers into the substrate, as is the case, for example, when compounding molding compounds.
- Another advantage of the process is the economically efficient saving of antimicrobial polymers, which is used in a Compounding, for example, remain ineffective in the matrix of the molding compound.
- undesirable changes in the physical properties of the substrates can be largely ruled out in this way, since only a very thin layer on the surface of the substrate is changed.
- the method according to the invention can be easily combined with other methods for surface treatment. For example, it is possible to carry out hydrophilization with water or acids after the thermally assisted application of the polymers.
- the surfaces treated in this way show an antimicrobial effectiveness that is permanent and resistant to environmental influences and physical stress.
- These coatings do not contain low molecular weight biocides, which effectively rules out the migration of ecologically problematic substances over the entire period of use.
- the present invention therefore relates to a process for the antimicrobial finishing of surfaces by thermal application of antimicrobially active polymers to this surface.
- Nitrogen and phosphorus functionalized monomers are preferably used for the production of the antimicrobial polymers, in particular these polymers are produced from at least one of the following monomers:
- the surface After or before the antimicrobial polymer is applied to the surface, the surface is heated.
- the temperature of the surface should at least reach the glass transition temperature of the antimicrobial polymer, better still exceed it. Beyond that
- Microblinding shows what further improves the adhesion of the antimicrobial polymer to the surface.
- the application of the polymer powder which can be finely ground in advance of the application and fractionated into defined grain sizes by sieving, can be done manually, e.g. by dusting with a sieve, or ideally also mechanically, e.g. by inflating or dusting directly behind you
- the surface to be antimicrobially equipped can be completely or partially covered with the polymers.
- the antimicrobial-treated surfaces can be rendered hydrophilic at or above the glass transition temperature of the antimicrobial polymer by contact with water or acids, in particular dilute organic or mineral acids.
- the accumulation of hydrohilic groups, which are often part of antimicrobial polymers, at the interface of the coated substrate further promote the antimicrobial effect.
- antimicrobial coatings optimized according to the invention for the production of antimicrobially active products and the products thus produced as such.
- Such products are preferably based on polyamides, polyurethanes, polyether block amides, polyester amides or imides, PVC, polyolefins, silicones, polysiloxanes, polymethacrylate or polyterephthalates, metals, glasses and ceramics, which have surfaces coated with polymers according to the invention.
- Antimicrobial products of this type are, for example, and in particular machine parts for food processing, components of air conditioning systems, coated pipes, semi-finished products, roofs, bathroom and toilet articles, kitchen articles, components of sanitary facilities, components of animal cages and houses, toys, components in water systems , Food packaging, controls (touch panel) of devices and contact lenses.
- the coatings according to the invention can be used wherever there is a lack of bacteria, algae and fungi, i.e. microbicidal surfaces or surfaces with non-stick properties. Examples of uses for the coatings according to the invention can be found in the following areas:
- Marine ship hulls, port facilities, buoys, drilling platforms, ballast water tanks House: roofs, cellars, walls, facades, greenhouses, sun protection, garden fences, wood protection
- Sanitary Public toilets, bathrooms, shower curtains, toiletries, swimming pool, sauna, joints, sealants - Food: machines, kitchen, kitchen items, sponges, toys, food packaging, milk processing, drinking water systems, cosmetics Machine parts: air conditioning, ion exchangers, process water, solar systems, heat exchangers, Bioreactors, membranes Medical technology: contact lenses, diapers, membranes, implants - utensils: car seats, clothing (stockings, sportswear), hospital facilities, door handles, telephone receivers, public transport, animal cages, cash registers, carpets, carpets
- the present invention also relates to the use of the hygiene products or medical technology articles produced according to the invention with coatings or processes optimized according to the invention.
- Such hygiene products include toothbrushes, toilet seats, combs and packaging materials.
- the term hygiene article also includes other items that may be come into contact with many people, such as telephone receivers, handrails of stairs, door and window handles as well as holding belts and handles in public transport.
- Medical technology articles are e.g. B. catheters, tubes, cover sheets or surgical cutlery.
