Definitions
- the invention relates to an alkali-stable sol-gel coating, to a process for producing an alkali-stable sol-gel coating and to the use thereof.
- DE 40 25 215 C2 describes the preparation of alkali-stable abrasion-resistant coatings. It describes the preparation of coating materials via the reaction of silanes containing non-hydrolyzable primary, secondary and / or tertiary amino groups with organic epoxides.
- the coating solutions must have at least one component with amino groups on the nonhydrolyzable part and a component with at least two epoxy groups.
- the alkali resistance in the dishwasher test (stored for 2 h in 3% solution of Somat) showed no shift change.
- siloxane KatZWasser Intermediate Silanol Cat
- the siloxane bond hydrolyzes in the alkaline medium under the catalytic influence of hydroxide ions to silanols. As a result, the inorganic polymer network and thus the coating is destroyed.
- the object of the invention is therefore to provide an alkali-stable sol-gel coating.
- condensation catalyst based on a.) secondary or tertiary bases (for example amino, mercaptosilanes) and / or b.) Lewis acids as metal alkoxides such as aluminum alkoxides,
- sol-gel systems based on silanes without organically functional side chain (MTEOS and higher-chain alkylsilanes to C30, TEOS) by condensation catalysts based on
- secondary or tertiary bases e.g., amino, mercaptosilanes
- tertiary bases e.g., amino, mercaptosilanes
- Lewis acids such as aluminum alkoxides, zirconium alkoxides, titanium alkoxides have significantly improved alkali stability, i. that even with 200 to 300 dishwasher cycles no failure is given.
- the required drying temperature of the coatings can be significantly reduced, for example transparent coatings can be produced which are used in drying Temperatures between 60 and 8O 0 C already good to very good adhesion and abrasion resistance on PVC, polycarbonate or other common plastics show. Depending on the application, the thickness of the applied layers is between 0.01 ⁇ m and 20 ⁇ m.
- the curing catalysts can either be added directly at the beginning of the sol-gel synthesis, or they can be added subsequently to the final coating solution.
- pot-life-resistant multicomponent coatings for example 2-component systems with binder and curing component.
- pigments or fillers can also be dispersed as desired.
- customary paint additives for example Byk additive for surface development / leveling or substrate wetting, pigment wetting
- paint practice as required.
- a development of the invention is that the coating with a solvent, in particular with water, to a solids content of more than 0.05 wt .-% and less than 20 wt .-% is diluted.
- a part of the alkoxysilanes is fluorinated or contains a hydrophilic side chain, in particular polyether.
- the metal alkoxides are preferably aluminum and zirconium alkoxides.
- the bases are silanes with a secondary amino group.
- the coating contains nanoparticles, in particular SiO 2 nanoparticles.
- the silane is hydrolyzed with the addition of acid and immediately after the hydrolysis up to Ih hydrolysis time, the catalyst is added. It is envisaged that the coating is carried out by rolling, flooding, spray painting, electrostatic spraying, spin coating, dipping or wiping.
- An embodiment of the invention is that the curing of the coating at room temperature (RT) to 1.200 0 C takes place.
- the coating is applied as a primer or as a thin layer with up to 3 micron layer thickness on the object to be coated.
- the coating according to the invention as a primer for hydrophobic coatings or photocatalytically active particles, Antikalk füren on chrome surfaces, stainless steel surfaces, PVC or polyester.
- the coating according to the invention as a base system for Antif ⁇ ngerprint-, photocatalytic, anti-scale coatings, matting agents, color pigments, leveling agents, for the impregnation of textiles, leather, paper or as a binder or additive for paint systems or polymers within the scope of the invention.
- the invention also includes the use of the coating according to the invention on household utensils, household appliances, kitchens and sanitary equipment, textiles, in particular pots, pans, housings of all kinds, fittings, covers, moldings, towel holders, paper dispensers, hand dryers, soap dispensers, shower heads, mirror frames, bathtubs. and washbasin closures, shower rods, shower panels, bathroom furniture, slats, PVC profiles (window frames, doors, conservatories), facade elements, shutter boxes, blinds, textiles, in particular technical fabrics, such as awnings, tent roofs and tarpaulins or (clothing) fabrics.
- the invention will be explained below with reference to exemplary embodiments.
- Primer 20.8 g of TEOS are stirred with 14.4 g of 0.1% H 2 SO 4 for 1.5 h (single-phase). Then is diluted with butyl glycol to 1% solids and treated with 1.2 g of N-methylaminopropyltrimethoxysilane.
- the primer On the cleaned chrome surface, the primer is sprayed on first. After 5 minutes (flash off), the functional layer is sprayed on. It is cured at 80 C for 20 minutes.
- the layer shows a clear beading behavior and a contact angle with water of 110 °.
- Kaikabgraphy is greatly facilitated by the coating.
- the coating also shows after two hours of storage in boiling dishwasher (10% Alio solution, pH 11.5) nor a contact angle greater than 100 ° and low adhesion to limescale.
- Primer 20.8 g of TEOS are stirred with 7.2 g of 1% H 2 SO 4 for Ih. Then it is diluted with demi water to 1% solids and treated with 1.4 g of 3-aminopropyltrimethoxysilane.
- the primer is sprayed on first. After 5 minutes (flash off), the functional layer is sprayed on. It is cured for 180 minutes at RT. Results: Compared to water, the layer shows a clear beading behavior and a contact angle with water of 105 °. Kaikabgraphy is greatly facilitated by the coating. Even after one hour of immersion in boiling dishwashing liquor (10% strength Alio solution, pH 11.5), the coating still shows a contact angle greater than 100 ° and low adhesion to limescale.
- the coated stainless steel samples show a clear beading behavior compared to water and a contact angle against water of more than 90 °.
- the coated samples show Antifmge ⁇ rinteigenschaften, ie applied fingerprints leave even after several hours no blue tarnishing traces and are therefore hardly noticeable on the surface.
- the fingerprints can be easily removed with a dry paper or cotton cloth. After boiling in tap water for 8 hours, no change in layer (turbidity, peeling, ...) can be detected. Limestone residues cooked on the surface can easily be removed with an acid surfactant cleaner.
- the samples were boiled for 8 h in dishwasher lye (10% Ali solution, pH 11.5) for the rapid test.
- Example 4 the coated samples were cleaned in a household dishwasher under standard conditions over a period of 300 program cycles. After none of the two test methods, a detachment or attack of the coating can be determined. The above-mentioned anti-fingerprint effect also remains.
- Example 4
- the solution is spray-coated onto PVC plan substrates and to polyester-topcoated metal panels, allowed to flash for 10 minutes and then dried for one hour at 7O 0 C in a convection oven.
- the coatings in each case show good adhesion and water storage stability (24-hour storage in demiwater at RT with subsequent adhesion test without complaint). In the QUV-A test, no yellowing or delamination of the coating can be detected after 500 hours.
- the coating exhibits good UV weatherability and can be used e.g. be used as a barrier layer system for the application of a photocatalytically active titanium oxide self-cleaning layer. Will be in o.g. Example 4 instead of N-butylaminolpropyltrimethoxysilane a propyltrimethoxysilane used, so at least curing temperatures of 130 ° C are necessary to achieve similar good mechanical and chemical resistance on the plastic substrates.
