Mittel und Verfahren zur Dimensionsstabilisierung von Holz oder Holzwerkstoffen

Mittel und Verfahren zur Dimensionsstabilisierung von Holz oder Holzwerkstoffen. Zur Dimensionsstabilisierung von Holz oder Holzwerkstoffen eignet sich eine Zusammensetzung, die ein Alkydharz und eine aromatische Verbindung mit mehr als 10 C-Atomen enthaelt.

EP 237703 A UPAB: 19930922 An agent (I) for the dimensional stabilisation of wood materials contains an aromatic cpd. with above 10C atoms (II) and an alkyd resin (III). A process for such stabilisation, using (I), is also claimed. The components are dissolved in an organic solvent and pref. emulsified with water, or suspended in water, or a soln. of (II) in a non-water-miscible solvent is emulsified with an aq. soln. of water-sol. (III); pref. amts. are 0.01-2 wt.% (II) and 5-20 wt.% (III); (II) is a non-alternating cpd., esp. fluoranthene. (I) also contains the usual amts. of the usual paint additives, e.g. drying agents, fungicides, bactericides, insecticides, emulsifiers, antifoam agents, UV-absorbers, flow promoters, crosslinkers, thickeners, pigments, or fire retardants. The treatment is carried out with or without the use of excess pressure and/or reduced pressure. Esp., the treatment is applied to beech wood. ADVANTAGE - Treatment with (I) enables the simple and economical stabilisation of wood against dimensional changes due to moisture uptake, weathering, etc.
