Definitions

  • the present invention relates to compositions and processes for treating wood substrates and, more specifically, compositions and processes for protective treatment of wood against bio-environmental degradation factors.
  • wood can be regarded as a hydrophilic bio-composite of fibrous cellulose and resinous lignins, and also containing substantial void volumes.
  • wood a renewable and biodegradable material, is vulnerable to environmental degradation factors and processes, which include both physical and micro-biological concerns.
  • Physical factors that contribute to degradation of wood include: UV radiation, seasonal temperature variations, humidity or condensed water. Wood possesses high degree of affinity for water and is in a dynamic equilibrium with air humidity, resulting also in dimensional instability.
  • wood will shrink or swell, one of the physical factors which promote degradation of wood.
  • the micro-biological, or bio- environmental factors that contribute to the deterioration of wood include fungi, mildew, algae, bacteria and, specifically, termites.
  • organic coatings in addition to their intended function of enhancing the aesthetic value of wood, also represent the most versatile surface protective technology of wood and usually are formulated to resist against environmental degradation factors, both physical and biological.
  • organic coatings do have significant limitations including: vulnerability to tannin staining (which results in degradation of their aesthetic value) and perhaps, more importantly, the inability to provide any "in depth” protection of wood substrates, such as necessary against termites. That is, protective organic coatings are not necessarily efficient at protecting the entire mass of the wood substrate, most notably the inner structure of wood substrates. It will be apparent that while other micro-biological destructive factors, such as fungus, mildew, bacteria and algae operate on the surface, termites attack through and consume the entire mass (depth) of wood substrates. Evidently, it would be desirable if, in addition to surface protection, protective coatings would provide "in depth” protection for wood, as well .
  • in depth protection of wood against biological degradation factors are based on liquid formulations of various biocides dissolved usually in diverse organic solvents.
  • in depth protection is realized by immersion of wood into such organic liquid formulations followed by drying and usually, by subsequent application of protective organic coatings.
  • immersion in organic solvents and, more specifically, drying of such treated wood are very time intensive operations and, consequently, most "in depth” protective technologies for wood generally are characterized by low productivity, which further results in significant release of organic solvents into the atmosphere .
  • Tannin staining is a spontaneous, cumulative, moisture driven process, resulting in degradation of aesthetic value of organic coatings, and in radical cases, in limited service life of coatings.
  • the consequence of wood's affinity for water, tannin staining is caused by water-soluble extractables (tannins) , and is more prevalent with water born organic coatings.
  • aqueous pretreatments for wood based on water soluble zirconyl compounds there are specialized stain inhibitor technologies known to the art, the most effective among them are the aqueous pretreatments for wood based on water soluble zirconyl compounds.
  • aqueous tannin stain inhibitor pretreatments are directly applied onto a wood substrate and allowed to absorb into the substrate. Subsequently, the pretreated substrates are dried, after which a primer coating is usually applied as an overcoat. With these surface treatment processes, the surface characteristics and texture of wood substrates are generally unaltered, while significantly reducing tannin staining activity.
  • U.S. Patent Nos. 5,759,705 and 5,733,666 also disclose the concept of an aqueous pretreatment that provides dual surface protective functions for wood. That is, this pretreatment inhibits tannin staining (of subsequently applied organic coatings) and provides surface protection against fungal or mildew attack on treated wood surfaces .
  • this pretreatment inhibits tannin staining (of subsequently applied organic coatings) and provides surface protection against fungal or mildew attack on treated wood surfaces .
  • a dual protective function aqueous pretreatment for wood can be obtained by addition of an effective amount of a biocide- active quaternary ammonium compound into aqueous solution of zirconyl acetate.
  • aqueous solutions of zirconyl salts function not only as effective carrier mediums for biocides intended for wood protection, but the zirconyl salts also act as functional mediums (i.e. stain inhibitor).
  • functional mediums i.e. stain inhibitor.
  • absorbed zirconyl species precipitate into pores of wood and react with and crosslink with the wood cellulose. Consequently, it appears that the process yields "in situ" immobilization of both, the biocide constituents of the treatment and of the indigenous soluble tannin species responsible for staining.
  • the aqueous protective treatments according to the present invention preserve the natural color, texture and the desired hydrophil character of wood substrates, which remain suitable for subsequent aqueous coating applications.
  • aqueous (carrier) solutions of various soluble zirconyl salts and of solutions modified by diverse guest cationic species can be carried out following procedures known to the art or, respectively, as described in U.S. Patent Nos . 5,759,705 and 5,733,666, herein incorporated by reference.
  • example of applicable zirconyl salts include acetates, nitrates, chlorides, sulfates, mixtures thereof, as well as zirconium ammonium carbonate, zirconium potassium carbonate and zirconium sodium carbonate .
  • Selected (guest) cationic species include: Hf(IV), Cu(II), Zn(II), Ce(III), Ce(IV), Ti(IV), Sn (II, IV) ), Sb(III), Bi(III), Al(III), and/or organic quaternary ammonium compounds and mixtures thereof.
  • bioactive compounds can be defined as organic or inorganic compounds possessing (selective or broad) toxic capacity against, for example, termites, fungi, mildew, mold, algae, yeast, or combinations thereof, the bio- factors which cause degradation of wood.
  • bio-environmental degradation should be considered as degradation or deterioration of wood substrate caused by the above specified bio-factors and, also, by such physical environmental factors as UV radiation, seasonal temperature variations, air humidity, condensation, and swelling/shrinking (dimensional instability) of wood.
  • biocides It is well known that the commercial usage of biocides is strictly regulated in the industry. Consequently, a relatively limited number of registered bioactive compounds constitute the active ingredients of a large arsenal of commercial biocide formulations marketed for protection of various water-based industrial products, such as adhesives, paints, construction materials, detergents, metalworking fluids, pulp, paper processing, textiles, wood and protective coating applications on wood.
  • bio-active compounds include:

  • Preparation of aqueous multi-functional protective treatments for wood and wood substrates according to the present invention is realized by incorporating (depending on their physical properties, by dissolution, or in dispersed or emulsified form) selected bio-active constituents or mixtures thereof, into the carrier solution of an aqueous zirconyl salt or carrier solution modified by guest cationic species.

  • defoamers may also be included.
  • the zirconyl compound Upon evaporation of the aqueous part of the multi-functional treatment, absorbed zirconyl species precipitate into pores of the wood or wood substrate and react with and cross- link with the wood cellulose.
  • the zirconyl compound not only inhibits spontaneous staining of coatings on the wood substrate, but, also, immobilizes the biocide in situ within the wood substrate, which further enhances the ability of the biocide to protect the wood in-depth, especially against termites . This is done while protecting the natural color, texture, and the desired hydrophil character of the wood or wood substrate.
