Abstract
Description
520 1g3 alkohol och att värmebehandla vid hög temperatur. Förfarandet har emellertid ej visat sig ge tillräckligt goda resultat och har därför ej ännu kommit till kommersiell användning (6 år efter prioritetsdatum). u Andamål med uppfinningen Ändamålet med uppfinningen är att åstadkomma ett effektivt träskyddsmedel som ger en torr och användbar yta på det impregnerade träföremålet. 520 1g3 alcohol and to heat treat at high temperature. However, the procedure has not been shown to give sufficiently good results and has therefore not yet come into commercial use (6 years after the priority date). Object of the invention The object of the invention is to provide an effective wood preservative which provides a dry and usable surface on the impregnated wood article.
Ett ytterligare ändamål är att möjliggöra användning av tallolj a, talloljedestillat eller fettsyror i impregneringsmedel för trä utan att ovan beskrivna problem uppstår.A further object is to enable the use of tall oil a, tall oil distillate or fatty acids in impregnating agents for wood without the problems described above arising.
Ett vidare ändamål är att åstadkomma impregnering av trä med ett medel baserat på tallolj a, talloljedestillat eller fettsyror utan att någon väsentlig uppvärmning erfordras.A further object is to provide impregnation of wood with an agent based on tall oil a, tall oil distillate or fatty acids without requiring any substantial heating.
Kortfattad beskrivning av uppfmriingen Dessa ändamål uppnås genom ett träskyddsmedel, där tallolja, fettsyror eller blandningar av fett- och hartssyror användes fór impregnering av trä, varvid en del av fett- och hartssyrorna förtvålas till kalciumsalter. Ca är av miljöskäl lämpligt att använda fór fórtvålning. Metallhalten i medlet är 1-10 viktprocent, räknat på mängden olja och syror.Brief description of the invention These objects are achieved by a wood preservative, where tall oil, fatty acids or mixtures of fatty and resin acids are used for impregnation of wood, whereby some of the fatty and resin acids are saponified into calcium salts. For environmental reasons, it is appropriate to use for soap. The metal content of the agent is 1-10% by weight, based on the amount of oil and acids.
Uppfmningen hänför sig således till ett sådant träskyddsmedel. Vidare hänför sig uppfinningen till användning av tallolj a, fettsyror eller blandningar av fett- 'och hartssyror förtvålade med kalcium såsom träskyddsmedel och till ett förfarande för impregnering, där en produkt vakuumtryckimpregneras med ett träskyddsmedel enligt uppfinningen, varvid medlet vid impregneringen uppvisar en temperatur om 40-90°C, varefter produkten tages upp ur träskyddsmedlet och får torka. 5203123 Detaljerad beskrivning av uppfinningen T räskyddsmedlet enligt uppfinningen kan som bas bestå av rå tallolj a, en blandning av rå tallolja och en tillsats av fett- och/eller hartssyror eller enbart hartssyror och/eller fettsyror. Fettsyroma kan utgöras av tallfettsyror eller av andra fettsyror.The invention thus relates to such a wood preservative. The invention further relates to the use of tall oil, fatty acids or mixtures of fatty and resin acids saponified with calcium as wood preservative and to a process for impregnation, wherein a product is vacuum pressure impregnated with a wood preservative according to the invention, the agent having an temperature of -90 ° C, after which the product is taken out of the wood preservative and allowed to dry. Detailed description of the invention The wood preservative according to the invention may as a base consist of crude pine oil a, a mixture of crude pine oil and an addition of fatty and / or resin acids or only resin acids and / or fatty acids. The fatty acids can consist of pine fatty acids or of other fatty acids.
Omvandlingen av en del av fett- och hartssyrorna till Ca-tvålar åstadkommes lämpligast genom att tallolj an i förväg får reagera med kalk.The conversion of some of the fatty and resin acids to Ca soaps is most conveniently accomplished by allowing tall oil to react with lime in advance.
Det är även möjligt att till talloljan eller fett- och hartssyrorna tillsätta en Ca-tvål av en lärnplig syra med ett pKa av ungefär samma storleksordning som den hos fett- och hartssyroma. Man kan således tillsätta Ca-tvålar av t.ex. tallfettsyror i hög koncentra- tion till tallolj an eller syrablandningen.It is also possible to add to the tall oil or the fatty and resin acids a Ca-soap of a mandatory acid with a pKa of approximately the same order of magnitude as that of the fatty and resin acids. One can thus add Ca soaps of e.g. tall fatty acids in high concentration in tall oil or the acid mixture.
Mängden kalciun1hydroxid kan variera mellan l och 10%, beräknat på olj emängden.The amount of calcium hydroxide can vary between 1 and 10%, calculated on the amount of oil.
Ca-tvålama fórtjockar tallolj an och fungerar troligen också som sickativ för oxidativ tvärbindning av fettsyrorna i oljan.The Ca-soaps thicken tall oil and probably also act as a sickle for oxidative crosslinking of the fatty acids in the oil.
Samma teknik med reaktion med kalk kan tillämpas på rena fettsyrablandningar eller på blandningar av fett- och hartssyror. Terpentin eller andra naturliga eller syntetiska ämnen, som förstärker träskydds-effekten, kan tillsättas' ' Tekniken kan även tillämpas för att förhindra att komprimerat trä återfjädrar vid uppfiiktning.The same technique of reaction with lime can be applied to pure fatty acid mixtures or to mixtures of fatty and resin acids. Turpentine or other natural or synthetic substances, which enhance the wood protection effect, can be added '' The technology can also be applied to prevent compressed wood from springing back when picked up.
I det följ ande beskrives uppfinningen närmare med hänvisning till utfóringsexempel. 520 1234 Exempel Utföringsexempel 1 Rå tallolja innehållande ca. 50% hartssyror och resten fettsyror och oförtvålbara substanser upphettades till 120°. 7 % kalciumhydroxid uppslammad i vatten tillsattes portionsvis under krafiig omrörning. När allt vatten kokat bort hölls temperaturen vid l20° ytterligare ca. 1/2 timme. Därefter var blandningen klar för användning. 5 cm tjocka furuplankor med både splint och kärnved impregnerades med Ca-tallolj e- blandningen. Plankorna evakuerades först 1/2 timme i autoklav till ett undertryck på ca. 0,05 atm. varefter Ca-tallolj eblandningen vid 70° sögs in så att den helt fyllde cylindern. Därefter fick trycket stiga till atrnosfarstryck med plankoma fortfarande nedsänkta i blandningen. Temperaturen hölls vid 70°. Plankoma förvarades nedsänkta 2 timmar varefter kvarvarande impregneringsvätska tappades ur. Plankoma togs ur cylindern och fick rinna av i en karmnare vid 70° över natt. De var då yttorra.In the following, the invention is described in more detail with reference to exemplary embodiments. 520 1234 Example Embodiment 1 Crude tall oil containing approx. 50% resin acids and the remainder fatty acids and unsaponifiable matter were heated to 120 °. 7% calcium hydroxide suspended in water was added portionwise with vigorous stirring. When all the water had boiled away, the temperature was kept at 120 ° for a further approx. 1/2 hour. Then the mixture was ready for use. 5 cm thick pine planks with both sapwood and heartwood were impregnated with the Ca-tall oil e-mixture. The planks were first evacuated for 1/2 hour in an autoclave to a negative pressure of approx. 0.05 atm. after which the Ca-tall oil mixture was sucked in at 70 ° so that it completely filled the cylinder. Thereafter, the pressure was allowed to rise to atmospheric pressure with the planks still immersed in the mixture. The temperature was maintained at 70 °. The planks were stored immersed for 2 hours, after which the remaining impregnating liquid was drained. The planks were taken out of the cylinder and also drained in a frame at 70 ° overnight. They were then surface dry.
Upptagningen av olja i splintveden var ca. 200 kg/m3 . Trots exponering för starkt solsken och mer än 30° lufltemperatur förblev plankorna smetfria.The uptake of oil in the sapwood was approx. 200 kg / m3. Despite exposure to strong sunshine and more than 30 ° lu fl temperature, the planks remained stain-free.
Utföringsexempel 2 Denna gång irnpregnerades 5 cm tjocka furuplankor med både splint och kärnved med en Ca-talloljeblandning innehållande 6% kalciurnhydroxid. Oljan hade förstärkts med ytterligare 10% hartssyror. Plankorna evakuerades först 1/2 timme i autoklav till ett undertryck på ca. 0,05 atrn. varefter Ca-talloljeblandníngen vid 70° sögs in så att den helt fyllde cylindern. Därefter höjdes trycket till 10 atrn. med plankoma fortfarande nedsänkta i blandningen. Temperaturen hölls vid 70°. Plankoma förvarades nedsänkta 2 timmar varefter kvarvarande impregneringsvätska tappades ur. Plankoma togs ur cylindem och fick rinna av i en kammare vid 70° över natt. De var då yttorra. Trots exponering för starkt solsken och mer än 30° lufitemperatur förblev plankoma smetfria. 520 923 Utföringsexempel 3 Tallfettsyror (SYLFAT® 2S, Arizona Chem.) upphettades till 120°. 7 % kalciumhydroxid uppslammad i vatten tillsattes portionsvis under kraftig omröming.Embodiment 2 This time, 5 cm thick pine planks were impregnated with both sapwood and heartwood with a Ca-tall oil mixture containing 6% calcium hydroxide. The oil had been fortified with an additional 10% resin acids. The planks were first evacuated for 1/2 hour in an autoclave to a negative pressure of approx. 0.05 atrn. after which the Ca-tall oil mixture was sucked in at 70 ° so that it completely filled the cylinder. Thereafter, the pressure was raised to 10 atr. with the planks still immersed in the mixture. The temperature was maintained at 70 °. The planks were stored immersed for 2 hours, after which the remaining impregnating liquid was drained. The planks were removed from the cylinder and run off in a chamber at 70 ° overnight. They were then surface dry. Despite exposure to strong sunshine and more than 30 ° lu fi temperature, the planks remained spotless. 520 923 Embodiment 3 Tallow fatty acids (SYLFAT® 2S, Arizona Chem.) Were heated to 120 °. 7% calcium hydroxide suspended in water was added portionwise with vigorous stirring.
När allt vatten kokat bort hölls temperaturen vid 120° ytterligare ca. l/z timme. Därefter var blandningen klar för användning. 5 cm tjocka furuplankor med både splint och kämved irnpregnerades med Ca-fettsyra- blandningen på samma sätt som i exempel 1 ovan. Plankoma togs ur cylindern och fick rirma av i en kammare vid 70° över natt. De var då yttorra. Upptagningen av olja i splintveden var ca. 200 kg/m3 . Trots exponering för starkt solsken och mer än 30° lufitemperatur förblev plankoma smetfria.When all the water had boiled away, the temperature was kept at 120 ° for a further approx. l / z hour. Then the mixture was ready for use. 5 cm thick pine planks with both splinter and core wood were impregnated with the Ca fatty acid mixture in the same way as in Example 1 above. The planks were removed from the cylinder and the belt was removed in a chamber at 70 ° overnight. They were then surface dry. The uptake of oil in the sapwood was approx. 200 kg / m3. Despite exposure to strong sunshine and more than 30 ° lu fi temperature, the planks remained spotless.
Utföringsexempel 4 En blandning av 75% tallfettsyror (SYLFAT® 2S) och 25% hartssyror (SYLVAROS® 85, Arizona Chem. ) upphettades till 120°. 7 % kalciumhydroxid uppslamrnad i vatten tillsattes portionsvis under krafiig omrörning. När allt vatten kokat bort hölls temperaturen vid 120° ytterligare ca. V2 timme. Därefter var blandningen klar för användning. 5 cm tjocka fiiruplankor med både splint och kärnved impregnerades med Ca-fettsyra- hartssyra-blandningen som i exempel 3 ovan. Till oljan sattes 10 % sulfatterpentin för att förstärka mögelbeständigheten. Plankorna togs ur cylindern och fick rinna av i en kammare vid 70° över natt. De var då yttorra. Upptagningen av olja i splintveden var ca. 150 kg/m3 .Trots exponering för starkt solsken och mer än 30° lufttemperatur förblev plankorna smetfiia.Example 4 A mixture of 75% pine fatty acids (SYLFAT® 2S) and 25% resin acids (SYLVAROS® 85, Arizona Chem.) Was heated to 120 °. 7% calcium hydroxide suspended in water was added portionwise with vigorous stirring. When all the water had boiled away, the temperature was kept at 120 ° for a further approx. V2 hours. Then the mixture was ready for use. 5 cm thick fi iru planks with both sapwood and heartwood were impregnated with the Ca-fatty acid-resin acid mixture as in Example 3 above. To the oil was added 10% sulphate turpentine to enhance mold resistance. The planks were removed from the cylinder and drained into a chamber at 70 ° overnight. They were then surface dry. The uptake of oil in the sapwood was approx. 150 kg / m3 .Despite exposure to strong sunshine and more than 30 ° air temperature, the planks remained batter fi ia.
Utföringsexempel 5 18 mm tjocka komprimerade spontade golvbrädor av furu med densiteten 1,09 g/cms impregnerades med Ca-fettsyra-hartssyra-blandriingen från exempel 4 ovan. Brädoma evakuerades först 2 timmar i autoklav till ett undertiyck på ca. 0,05 atrn. varefter oljan vid 70° sögs in så att den helt fyllde cylindern. Därefter fick trycket stiga till 520 123 6 atmosfärstiyck med brädoma fortfarande nedsänkta i blandningen. Efter 4 timmar togs de upp ur blandningen och fick rinna av i en kammare vid 50° över natt. De var då yttorra. Oljeupptagningen var ca. 15% räknat på utgångsvikten och inträngningen från ytan ca. 3 mm. Ingen svällning kunde registreras. Brädorna kunde lätt samrnanfogas. Återsvällningen, efter att brädoma fått lufitorka, när vattendroppar applicerades på ytor och i fogar, var försumbar.Embodiment Example 18 18 mm thick compressed plywood floorboards of 1.09 g / cm 2 were impregnated with the Ca-fatty acid-resin acid mixture ring from Example 4 above. The boards were first evacuated for 2 hours in an autoclave to a pressure of approx. 0.05 atrn. after which the oil was sucked in at 70 ° so that it completely filled the cylinder. Thereafter, the pressure was allowed to rise to 520 123 6 atmospheric pressures with boards still immersed in the mixture. After 4 hours they were taken out of the mixture and did not drain in a chamber at 50 ° overnight. They were then surface dry. The oil intake was approx. 15% calculated on the starting weight and the penetration from the surface approx. 3 mm. No swelling could be detected. The boards could be easily joined together. The re-swelling, after the boards had been allowed to dry, when water droplets were applied to surfaces and joints, was negligible.
