Definitions
- the invention relates to a new cover layer for electrophotographic printing rollers with improved scratch resistance.
- the new cover layer is suitable for copier and printer rollers.
- Electrophotography is a very common process in printing and duplicating technology. It is based on the fact that in a charge-formation layer after exposure, charges are released which can convert a previously applied charge into a charge image. By means of charged toner particles, an image can thus be produced on the roller which, after contact with paper, is transferred to the latter. To achieve high adhesion and resistance to paper support, the charged toner particles are embedded in special resins. After transferring them to paper, they can thus be thermally fixed.
- electrophotographic printing rollers consist of an aluminum cylinder provided with an adhesive layer. Applied thereon is: a) a charge-generating layer with a thickness of 0.2 to 3 ⁇ m, b) a charge-transport layer with a thickness of 10 to 40 ⁇ m c) a 0.5 to 5 micron thick topcoat
- the charge-generating layer often contains, as a photosensitive layer, phthaloyl cyanine compounds such as titanoyl phthalocyanine in dispersed form in a polymer matrix.
- the polymer matrix is usually a synthetic resin binder based on polycarbonate, polyester, polyamide, polyepoxide, polysilicone resin or copolymers based on acrylic or methacrylic acid esters.
- the charges generated in this layer are taken up by the charge transport layer and transferred to the surface.
- the charge transport layer is intended to hold the charges of the recording material in the dark as an insulating layer. Hydrazone compounds, which are also dispersed in dispersed form in special resins, usually accomplish this task.
- the cover layer acts as a protective layer and significantly influences the print result, in particular it is intended to protect the print cylinder surface against mechanical damage by toner particles and paper. Furthermore, it should meet other requirements such as high transparency matched electrical properties such as low transverse conductivity, no isolator function, specific residual potential, etc. high solvent resistance, preferably with barrier function, to allow the use of liquid toner easy cleaning properties, no unwanted adhesion of toner particles high oxidation resistance, low susceptibility to the ozone generated during charging and nitrogen oxide meet.
- EP 1 030 223 describes crosslinked polysiloxanes in combination with dihydroxymethyltriphenylamine and methyltrimethoxysilane.
- EP 1 271 253 proposes pigmented protective layers based on phenolic resins and Teflon dispersions. By adding fluorosilane coupling agent good anchoring of the antimony-zinc oxide pigments is achieved with good lubricity.
- Teflon particles as a lubricant in binder mixtures of polyurethane resin and polyvinyl butyral.
- JP 2004-020649 proposes the use of aromatic, N-substituted polyepoxides in combination with silane mixtures of phenyltriethoxysilane, methyltriethoxysilane and aminopropyltriethoxysilane.
- the object is achieved with a protective layer of a) 50-75% by weight of cycloaliphatic, polyfunctional epoxides b) 20-60% by weight of amino-functional silica nanoparticles c) 0-2% by weight of perfluoroalkyltrialkoxysilane.
- the cycloaliphatic epoxides can be used both as monomers and as polymers. Your epoxy functionality must be at least two.
- Examples of such compounds are: hydrogenated bisphenol A diglycidyl ether hydrogenated bisphenol F diglycidyl ether hexahydrophthalic acid diglycidyl ether.
- the epoxides are used in the form of 10 to 35% strength by weight solutions in isopropanol, n-butanol or methoxypropanol.
- Aliphatic epoxides such as, for example, trimethylolpropane triglycidyl ether, hexanediol diglycidyl ether or pentaerythritol tetra- surprisingly, glycidic ethers are unsuitable because they cause deleterious electrical layer properties that prevent the printing of "single dots.” Residual potentials of 0 to 5 volts are determined on such layers.
- Aromatic epoxides are likewise not suitable for the purposes of the invention, since they require the use of ketones and aromatics as solvents. Such solvents often cause film disruption by solubilization of the charge transport layer.
- the synthesis of the amino-functional silica nanoparticles is carried out in a known manner by sol / gel technology by hydrolyzing aminoalkyl trialkoxysilanes in alcohols and condensing them into solid particles.
- aminoalkylsilanes examples are:
- amino-functional silica nanoparticles which are prepared by surface functionalization of aerosils according to DE 3 212 771, DE 3 709 501, US Pat. No. 3,986,997.
- composition according to the invention may also contain up to 2% by weight of a perfluoroalkyltrialkoxysilane.
- fluorosilanes examples include tridecafluorooctyltriethoxysilane or the Perfluoropolyether silanes Fluorolink 7007 and Fluorolink S 10 from Solvay.
- the particle size of the silica nanoparticles is in the range of 5 to 40 nm, preferably 5 to 20 nm.
- the amino-functional silica nanoparticles have a high reactivity with epoxides, these nanoparticles must be stored separately from the epoxide solutions and handled as a two-component system.
- the coating of the pressure rollers can be carried out in a known manner by spraying, dipping or knife coating. Depending on the concentration of the components, a processing time of 8 to 120 hours is possible. Thereafter, a gelation occurs.
- the layer After coating, the layer is aerated at room temperature or elevated temperatures for 15 min and cured at 110 to 13O 0 C for about 30 min. As a result of this thermal curing, a highly cross-linked hybrid polymer with covalently bonded silica nanoparticles is formed.
- the cover layers of the invention are transparent, solvent-resistant and are characterized by a significant improvement in the scratch resistance. They allow a good adjustment of the residual potential and give a very good detail reproduction. A complex and often difficult reproducible dispersion of the nanoparticles is not required.
- the topcoats are suitable for both dry and liquid toners.
- 180 ml of isopropanol and 180 ml of n-butanol are mixed at room temperature in a temperature-controlled stirred vessel.
- To this mixture is added 80 ml of aminopropyltriethoxysilane and 40 ml of distilled water and stirred for 30 minutes.
- Example 1 The procedure of Example 1 is followed substituting 80 ml of N- (2-aminoethyl) -3-aminopropyltrimethoxysilane for aminopropyltriethoxysilane.
- a sol is obtained with the following characteristics: Solids content: 13.2% pH: 11.2
- Example 1 The procedure of Example 1 is maintained with the following composition: 180 ml of isopropanol 180 ml of n-butanol 30 ml of phenyltriethoxysilane 60 ml of tetraethoxysilane 45 ml 0, ln trifluoroacetic acid
- a sol is obtained with the following characteristics: Solids content: 7.3% pH: 2.9
- sol A 4/6 50 g of hexahydrophthalic acid diglycidyl ether (10% strength in isopropanol)
- the mechanical surface properties are characterized by determining the surface hardness according to Erichsen (ISO 15184) and by contacting the surface with a hard polyamide fabric (Glitzi sponge, Scotch-Britt sponge), which is loaded with 200 and 500 g respectively.
- the surface injuries caused by this contacting are quantified by ratings of 1 to 5.
- Grade 1 is awarded for completely undamaged, Grade 5 for very badly damaged surfaces. Table 1 below summarizes the results:
- the layers After 15 minutes of air drying, the layers are cured for 30 minutes at H 2 O.
- the electrical properties of the cover layer are characterized by the DE 3 924 904 determined residual potential. Furthermore, the reproduction of the smallest still printable detailed information ("single dots") after 10 and 7000 copies is determined and in Table 2 the results are summarized.
- the protective layers according to the invention corresponding to compositions 5/4 to 5/7 show a considerable improvement in the printing properties.
- Protective layers containing known polysiloxanes (5/2) or aliphatic epoxides do not permit the printing of "single dots.”
- Protective layers based on polycarbonate show a significant impairment in reproduction as the number of copies increases.
