Claims
- 1. A non-water and non-solvent based material for treating wood comprising a preservative and a carrier, the carrier being selected such that it remains mobile within the wood and provides for migration of the preservative within the treated wood, said carrier including:
(a) a drying oil selected from linseed oil, fish oil or another drying oil, and (b) an extender, such as heating oil; said preservative including an insecticide, termicide, fungicide, mouldicide, or the like, or mixtures thereof.
- 2. The material of claim 1, wherein the carrier contains between 10 and 90% of extender.
- 3. The material of claim 1, wherein the carrier contains between 30 to 70% of extender.
- 4. The material of claim 1, wherein the carrier contains 40 to 60% of extender.
- 5. The material of claim 1, wherein the preservative is an insecticide or termidicide selected from the group consisting of synthetic pyrethroid, permethrin, cypermethrin and imidachloprid.
- 6. The material of claim 1, wherein the preservative is a fungicide, or mouldicide selected from the group consisting of iodopropynylbuthylcarbamate (IPBC), organic tin compounds such as tributyltin napthenate (TBTN), organic copper compounds such as copper 8 quinolinolate and copper napthenate, organic zinc compounds, quaternary ammonium compounds, tertiary ammonium compounds, isothiazolones, triazoles such as tebuconazole, boron compounds and mixtures thereof.
- 7. The material of claim 1 wherein the preservative is selected from the group consisting of 3-benzothien-2-yl-5,6-dihydro-1,4,2 oxathiazine-4-oxide (Bethoguard®) and bis-(N-cyclohexyldiazeniumdioxy) copper (“Cu-HDO”).
- 8. The material of claim 1, wherein the material for treating wood includes drying agents to accelerate drying of the drying oil.
- 9. The material of claim 8, wherein the drying agent is selected from the group consisting of cobalt, manganese, zirconium, copper napthenate and mixtures thereof.
- 10. The material of claim 1, wherein the preservative content in the treatment material is below 5%.
- 11. The material of claim 1, wherein the preservative content is less than 2% of the mixture.
- 12. The material of claim 1, wherein the preservative content is less than 1% of the mixture.
- 13. The material of claim 1, wherein the carrier is selected to remain mobile within the wood such that it provides for redistribution or migration of the preservative to exposed surfaces of the wood.
- 14. The material of claim 1, wherein the carrier is selected to remain mobile within the wood for up to several months.
- 15. The material of claim 1, wherein the carrier is selected to remain mobile within the wood for up to about four weeks.
- 16. The material of claim 1, wherein the carrier is selected to provide for migration along the grain of the wood and/or across the grain.
- 17. A method of treating wood comprising contacting the wood with a material comprising a preservative and a carrier, the carrier being selected such that it remains mobile within the wood and provides for migration of the preservative within the treated wood, said carrier including:
(c) a drying oil selected from linseed oil, fish oil or another drying oil, and (d) an extender, such as heating oil; said preservative including an insecticide, termicide, fungicide, mouldicide, or the like, or mixtures thereof.
- 18. The method of claim 17, wherein the carrier contains between 10 and 90% of extender.
- 19. The method of claim 17, wherein the carrier contains between 30 to 70% of extender.
- 20. The method of claim 17, wherein the carrier contains 40 to 60% of extender.
- 21. The method of claim 17, wherein the preservative is an insecticide or termidicide selected from the group consisting of synthetic pyrethroid, permethrin, cypermethrin and imidachloprid.
- 22. The method of claim 17, wherein the preservative is a fungicide or mouldicide selected from the group consisting of iodopropynylbuthylcarbamate (IPBC), organic tin compounds such as tributyltin napthenate (TBTN), organic copper compounds such as copper 8 quinolinolate and copper napthenate, organic zinc compounds, quaternary ammonium compounds, tertiary ammonium compounds, isothiazolones, triazoles such as tebuconazole, boron compounds such as trimethyl borate, and mixtures thereof.
- 23. The method of claim 17 wherein the preservative is selected from the group consisting of 3-benzothien-2-yl-5,6-dihydro-1,4,2 oxathiazine-4-oxide (Bethoguard®) and bis-(N-cyclohexyldiazeniumdioxy) copper (“Cu-HDO”).
- 24. The method of claim 17, wherein the material for treating wood includes drying agents to accelerate drying of the drying oil.
- 25. The method of claim 24, wherein the drying agent is selected from the group consisting of cobalt, manganese, zirconium, copper napthenate or mixtures thereof.
- 26. The method of claim 17, wherein the preservative content in the treatment material is below 5%.
- 27. The method of claim 17, wherein the preservative content is less than 2% of the mixture.
- 28. The method of claim 17, wherein the preservative content is less than 1% of the mixture.
- 29. The method of claim 17, wherein the carrier is selected to remain mobile within the wood such that it provides for redistribution or migration of the preservative to exposed surfaces of the wood.
- 30. The method of claim 17, wherein the carrier is selected to remain mobile within the wood for up to several months.
- 31. The method of claim 17, wherein the carrier is selected to remain mobile in the wood for up to about four weeks.
- 32. The method of claim 17, wherein the carrier is selected to provide for migration along the grain of the wood and/or across the grain.
- 33. The method of claim 17, wherein the wood is contacted with a mixture of preservative and carrier by pressure application, spraying, dipping, rolling, painting, or combinations thereof.
- 34. The method of claim 17, wherein the wood is dipped in a mixture of preservative and carrier from between a few seconds up to several minutes.
- 35. The method of claim 17, wherein the wood is dipped in a mixture or preservative and carrier from around 5 seconds up to about 60 seconds.
- 36. The method of claim 17, wherein the wood is contacted with a sufficient quantity of preservative and carrier to provide an uptake of between 10 to 100 L/m3.
- 37. The method of claim 17, wherein the method is applied to radiata pine heartwood, radiata pine sapwood, slash pine (pinus elliotti) heartwood or sapwood, or Douglas fir (psuedotsuga menziesii) heartwood and sapwood.
- 38. The method of claim 17, wherein the method is applied to wood composites including particle board, plywood, medium density fibreboard (MDF) or oriented strand board (OSB).
