Definitions
- Coating agents curable by UV radiation processes for producing coatings from these coating agents and their use
- the invention relates to coating compositions curable by UV radiation, processes for producing coatings from these coating compositions and their use.
- peroxidically curable polyester paints for example paraffin-containing paints based on phthalic anhydride or paraffin-free paints with a glossy surface based on allyl ether.
- the layers were applied using customary paint application methods such as rolling, pouring or spraying.
- the viscosities of these polyester paints are adjusted to a viscosity in the range from about 150 to 250 mPa.s at 21 ° C. so that they are sprayable.
- the polyester lacquers can be applied by compressed air spraying, with the polyester and peroxide components being mixed using the intermixing method and sprayed from a pot. It is also possible to run the two-component spray process, the peroxide component and the polyester component separately to the gun and mix in there in the spray jet.
- the wooden base is used for spray painting by pickling, priming, if necessary patinating and Isolate prepared. After drying, the polyester lacquer layer is sprayed onto the substrate prepared in this way.
- the sprayed polyester paints thixotropize so that they also adhere to vertical surfaces.
- they contain inorganic and / or organic thixotropic agents.
- the individual layers are gelled and UV-cured by UV radiation.
- the intermediate gelation and intermediate curing takes place through the radicals released from the peroxide component by UV radiation and, depending on the setting of the radiation, takes about 10 to 30 minutes for each individual layer.
- the final hardening of the entire layer is carried out by additional radiation with a high-pressure or medium-pressure mercury vapor lamp.
- the shrinking parts that are released into the atmosphere in polyester / styrene systems consist predominantly of monostyrene or of styrene oxide, which is formed from monostyrene during the polymerization. Both substances are volatile organic compounds (VOC), which are undesirable in the sense of VOC regulations. Cyclohexanone, which arises from the cyclohexanone peroxide used for the polymerization, is also undesirable.
- the polyester layer contains more or less volatile constituents, which are also gradually released.
- volatile constituents which are also gradually released.
- these are phthalates and solvent residues.
- the VOC value as a measure of the volatile constituents, is around 1,500 ppm for the above-mentioned gloss coating systems and around 1,700 to 2,200 ppm for polyester coatings containing paraffin.
- UV-curable acrylic lacquer system lends itself.
- radiation-curable acrylate lacquers have been applied by customary lacquer application methods, for example by thin-layer application by means of rollers, the layer thicknesses of the applied layers being 5 to 15 ⁇ m. These thin layers are also applied in several layers, gelled and sometimes even sanded. The intermediate gelling, which is necessary for the adhesion of the next layer, is achieved by UV radiation.
- viscosities of about 300 to 800 mPa.s have been set.
- the object of the invention is to develop a liquid coating composition curable by means of UV light which has good sprayability, good film properties in the end result and a low VOC value.
- liquid coating agent which can be hardened by UV radiation and which contains the following constituents:
- a thixotropic agent 0.1-5% by weight of a thixotropic agent
- the invention further relates to a method for producing a coating on a prefabricated wooden surface, in which the coating agent is applied by hot spraying at 35 to 80 ° C in several layers with a layer thickness of 50 to 800 microns and applied in each layer by UV radiation.
- the painted, hardened wooden component can be milled, sanded, polished and light-resistant, chemical-resistant and moisture-resistant.
- moisture resistance As far as moisture resistance is concerned, a 500h condensation storage (at 40 ° C and 95% relative humidity) is required.
- the coating agent according to the invention is low in emissions, ie has a low VOC value of ⁇ 100 ppm.
- the invention relates to coating compositions curable by UV light, which use acrylic resins as coating raw materials.
- the importance of the invention is based in particular in the fact that solvent-free and low-emission paints are used which lead to a variety of desired properties.
- the coating composition contains about 5 to 80% by weight, preferably about 10 to 60% by weight, of polyfunctional crosslinkable acrylates or methacrylates.
- Starting materials are, depending on the structural structure, polyether, polyester, epoxy, urethane, melamine, silicone acrylates and / or methacrylates and acrylated and / or methacrylated polyacrylates.
- the materials include all molecular weight ranges between monomers, oligomers and polymers and may contain other functional groups in addition to the acrylate group.
- the molecular weights are in a range from about 500 to 6,000, the composition being selected so that application by spraying is ensured and enough low molecular weight components are present so that a total viscosity of 150 to 250 mPa.s at 21 ° C results. On the other hand, to ensure good film properties of the end product, high-molecular components must also be present.
- the coating composition contains about 5 to 75% by weight of a reactive diluent.
- the reactive diluents are monomers or also low-viscosity oligomers that replace volatile organic solvents. They have molecular weights in the range from about 50 to 500.
- the reactive diluents which contain radical-polymerizable radicals, are selected from the group of acrylic esters of simple alcohols, hexanediol diacrylate, hydroxymethylethylacrylate, hydroxypropyl acrylate, polyethylene glycol diacrylate, trimethylolpropane triacrylate, dipropylene glycol diacrylate or mixtures of the same, tripropylene glycol.
- Styrene-free unsaturated acrylate and polyester acrylate resins are available, for example, from BASF under the trade names Laromer® and Sartomer®.
- a thixotropic agent based on silicon dioxide is added to adjust the thixotropy of the coating agent.
- fumed silica is preferred in an amount of 0.5 to 1.5% by weight.
- the thixotropic agent is combined with the resins or resin components of Van der Waals bonds, which bring about a reduction in viscosity under the action of mechanical forces during processing. After the mechanical stress has ceased, the thixotropy is reset, thereby preventing vertical surfaces from running off.
- photoinitiators which are added in an amount of about 0.01 to 10% by weight, preferably 1 to 3% by weight. These are compounds which, under the action of high-energy radiation, form start radicals which trigger the polymerization of the coating composition.
- UV initiators which can be used in the context of the present invention are, for example, benzoin ether, benzil dimethyl ketal, diethoxyacetophenone, hydroxy ketones, aminoketones, benzophenones, a mixture of benzophenone and 1-hydroxy-cyclohexyl-phenyl ketone (trade name Irgacure® from Ciba Specialty Chemicals, Basel), 2-hydroxy 2-methyl-1-phenyl-propan-1-one (trade name Darocur® from Ciba Specialty Chemicals, Basel), monoacylphosphine oxides and bisacylphosphine oxides, or mixtures thereof (trade name Lucirin® from BASF).
- benzoin ether benzil dimethyl ketal
- diethoxyacetophenone hydroxy ketones
- aminoketones benzophenones
- benzophenones a mixture of benzophenone and 1-hydroxy-cyclohexyl-phenyl ketone
- additives are also added to the coating agent.
- additives to increase the scratch resistance, heat resistance and light fastness. They can optionally be contained in amounts of approximately 0 to 20% by weight.
- surface-active substances are added in concentrations of 0.0001 to 2% by weight, for example organic silicone compounds of the polymethylsiloxane type (trade name Baysilone® from Bayer).
- Stabilizers or inhibitors which intercept potential start radicals.
- the amounts used are of the order of about 0 to 20% by weight, preferably from 0 to 8% by weight.
- Stabilizers or inhibitors which can be used in the context of the present invention can include hydroquinone, hydroquinone monomethyl ether, p-benzoquinone, p-tertiary-butylcatechol, phenothiazine, 2,6-di-tertiary-butylhydroxytoluene, sterically hindered amines and benzotriazole (trade name Tinuvin® from Ciba Specialty Chemicals , Basel).
- the coating agent of the present invention is a material that has no short-life pot life.
- the polymerisation is only triggered by the action of UV radiation by UV initiators.
- the consequence of this is that sprayed material, which for example reaches the conveyor belt, is recyclable and can be recycled by appropriate devices.
- the functionality of the reactive diluents and thus their crosslinking action is, in addition to the viscosity, the dilution action and volatility, an important selection criterion when using the same. If stabilizers remain in the product during manufacture, the paint properties must not be impaired. At most UV initiators are emitted from the product.
- reaction conditions with regard to temperature, mixing etc., as well as the stabilizer and UV initiator system, must be carefully coordinated. Temperatures of the reaction system of about 110 to 130 ° C should not be exceeded.
- a coating batch is made by simply mixing the components below with heating (to about 40 ° C) to ensure the dissolution of these components.
- the mixture has a viscosity of about 550 mPa.s (measured at 21 ° C). 60 parts by weight of epoxy acrylate, MW: 2,500;
- UV initiator consisting of a mixture of monoacylphosphine oxide and bisacylphosphine oxide

- the polymerization is carried out by means of UV radiation. It can advantageously also be carried out in an inert gas atmosphere, for example under nitrogen gas, to exclude the polymerization-inhibiting atmospheric oxygen. Since various additives are considered hazardous substances, for example there are risks of skin contact, it is advantageous to apply the layers of paint in a closed chamber.
- the UV irradiation time required for gelling and / or curing depends on the temperature and the chemical composition of the coating agent, on the type and power of the UV source, on its distance from the coating agent and on any inert gas atmosphere that may be present.
