Definitions
- the present invention relates to the treatment of wood or
- Wood products in particular for preventing the escape or migration of tannin from the wood. This leakage can be effectively prevented by treating the wood with a gelatin solution and / or with a wood treatment agent containing gelatin and derivatives.
- tannins are polyhydroxyphenols which are soluble in both water, ethanol and acetone.
- the vegetable tannins vary significantly in their chemical structure and biological activity. They are found in the wood bark of oaks, birch and chestnuts, in tropical hardwoods, in the pericarp of walnut, in grapes and in plant galls. Monomeric groups of tannins are also found in hops as well as in black and green tea.
- Wood is widely used in the area of home, yard and garden as a building material.
- Wood treatment has recently become more and more important for so-called low-emission agents, especially when the treatment is required for wood indoors.
- wood When using wood as a building material e.g. As wooden ceilings or doors and windows, it is therefore often treated with water-soluble paints.
- a common problem is the bleeding of water-soluble
- Wood ingredients especially the tannins from the wood body, despite one
- Tannin migration to use a wood paint containing a linear, partially deacylated poly (N-acyl) alkylenimine in the formulation This polymer can be previously applied directly to the wood or together with the wood paint in the formulation on the wood.
- Zirconium carbonates incorporated in the polymeric wood paints. It has been coated with these means the wood and after
- Aluminum and tin compounds formulated in the wood paints Aluminum and tin compounds formulated in the wood paints.
- organo-inorganic compounds e.g. one
- Neoalkoxy titanate incorporated into the coating compositions is disclosed as a tannin blocker.
- These titanium compounds preferably have one or more amino functional groups. Also relevant in this connection is the US Pat. No. 6,531,223 in which a coating without a primer, ie a primer coat, is proposed.
- Coating essentially contains two components, namely one
- water-soluble latex emulsion and so-called microspheres which absorb little water.
- microspheres include e.g. Sodium, or potassium aluminum silicate particles, glass beads, hollow glass beads, or also expanded acrylonitrile / vinylidene chloride copolymers u.a. It was essential here that the diameter of these particles, if possible not more than 210 [im should be.
- Gelatin is a mixture of polypeptides, depending on the extraction with molecular weights of about 13500 to 500000 (determined by SDS gel electrophoresis or
- Amino acid composition largely matches that of the collagen from which it is derived. It is odorless and practically colorless, insoluble in ethanol, ethers and ketones, soluble in ethylene glycol, glycerol, formamide and acetic acid.
- essentially a gelatin solution which no longer exhibits the ability to gel, which is obtainable from a gelatin powder by dissolution in water can be used.
- tanning where tannin is used as a tanning agent, especially for cross-linking the collagen present in the skins
- the inventors have found that the use of gelatin, as a collagen degradation product, in the prevention of tannin migration can be used successfully and very good results.
- tannins or tannins obtained from oak or spruce bark, mimosa and sumac and other wood species are used as bark tannins (“Gerberlohe"), in which process the collagen molecules apparently become tannins with the aid of tannins are, respectively contain, networked and thus permanently bound.
- the tannin is converted into an insoluble gelatin (collagen) -Tannin complex, it forms a water-insoluble, colorless precipitate. In this way, tannin is virtually bound and prevents staining and bleeding.
- gelatine can be spread or sprayed directly onto the wood surface as an aqueous solution. After this treatment, the wood can be aftertreated with any paint - the desired
- the concentration of the aqueous gelatin solution is between 2 and 8 wt .-% moves.
- Such a solution can be easily prepared by dissolving a gelatin powder in cold or warm water.
- Gelatin powders are commercially available, in particular the types from Gelita, for example Collagen A or Biogel, for example Vitagel PLPR.
- the amount of gelatin, which is applied per cm 2 of wood surface, is 5 to 10 mg / m 2 based on the wood surface.
- Wood paints incorporate, which is possible without problems, because the gelatin has no adverse interactions with the wood paints or their components. In this approach, but the
- Gelatine 1 liquid gelatine with 20% active ingredient
- Gelatine 2 gelatine in powder form with 100% active ingredient / sourced from Switzerland
- Gelatine 3 powdered gelatin containing 100% active ingredient / based on
- the gelatin solutions were each thinly applied to an oak board (30 ⁇ 11 cm) with a brush and dried for 24 hours at room temperature.
- the total order amount was always 2 g.
- each of the two gelatin powders prepared a 10% aqueous solution, in all cases with distilled water.
- gelatin solutions prepared were, as in Example 1, on a
- Oak board (30 xx11 cm) applied thinly with a brush and dried for 24 hours at room temperature. Here, the total order amount was always 2 g. After drying, a white wood finish with a layer of 150 ⁇ layer thickness was applied to each pretreated piece of wood. The boards were at 25 ° C and 50% rel. Humidity stored for 1 week and then with a
- Photometer of the brand "Minolta CR 200" carried out a whiteness measurement.
- gelatin 2 showed the best results. Therefore, gelatin 2 was selected for Example 3.
- Example 3 Gelatin was incorporated into the wood treatment agent (white wood finish)
- the finished samples were stored for 24 hours at room temperature in a sealed box. Thereafter, they were applied with a doctor in amounts of 150 and 250 ⁇ layer thickness on an untreated oak board and at 25 ° C and 50% rel. Humidity stored for 1 week.
- the whiteness measurement was carried out with the photometer "Minolta CR 200" / predecessor model of CR 400 /.
- the wood varnish used in the tests has the frame formula below:
