Wojciech Olpinski Wlasciciel patentu: Glówny Instytut Górnictwa, Katowice (Polska) Srodek do przeciwgrzybowego zabezpieczania drewna Przedmiotem wynalazku jest srodek do przeciw- grzybowego zabezpieczania drewna, oparty na so¬ lach kwasu fluorokrzemowego.Stosowane dotychczas do przeciwgrzybowej im¬ pregnacji drewna sole cynkowe, magnezowe lub amonowe kwasu fluorokrzemowego maja wlasnosci przeciwgrzybowe, jednak zle wnikaja w drewno, co w przypadku odsloniecia nienasyconych warstw wewnetrznych, na przyklad pod wplywem zgnia¬ tania lub zginania, powoduje gnicie i calkowita utrate wlasnosci wytrzymalosciowych elementów drewnianych.Urotropina oraz produkty kwasów tluszczowych 2 kwasami ammokarboksylowymi byly dotychczas stosowane jako dodatki do roztworów wodnych soli kwasów chloroligninosulfonowych w celu wyelimi¬ nowania dzialania korodujacego tych roztworów oraz ich samozakwaszania w czasie magazynowania.Dodatki te nie powodowaly polepszenia wlasnosci przeciwgrzybowych srodka opartego na solach kwa¬ sów chloroligninosulfonowych.Przedmiotem wynalazku jest srodek przeciwgrzy- bowy oparty na solach kwasu fluorokrzemowego o ulepszonych wlasnosciach przeciwgrzybowych oraz dobrze wnikajacy w drewno.Okazalo sie, ze 1 do 33%-owy roztwór wodny za¬ wierajacy od 90% do 99,6% wagowych soli kwasu fluorokrzemowego, od 0,2% do 5% wagowych uro¬ tropiny oraz od 0,2% do 5% wagowych kondensatu kwasów tluszczowych z kwasami aminokarboksylo- wymi najkorzystniej z hydrolizatami bialka, sku¬ tecznie zabezpiecza drewno przeciwgrzybowo i nie¬ spodziewanie powoduje podwyzszenie wlasnosci toksycznych soli kwasu fluorokrzemowego. Rola 5 kondensatu kwasów tluszczowych z kwasami ami- nokarboksylowymi w srodku wedlug wynalazku polega na podwyzszeniu przenikalnosci soli kwasu fluorokrzemowego w strukture wewnetrzna grzy¬ bów niszczacych drewno. io Srodek wedlug wynalazku doskonale wnika w drewno i tym samym zabezpiecza przeciwgjjzyjbowo wszystkie warstwy wewnetrzne drewna* ftodek ten nie powoduje korozji urzadzen stalowych* w trakcie sporzadzania, magazynowania oraz nasyfca- 15 nia drewna srodkiem. Ze wzgledu na male ilosci wprowadzonych do soli kwasu fluorokrzemowego dodatków urotropiny oraz kondensatu kwasów tlu¬ szczowych z kwasami aminokarboksylowymi oraz duze rozcienczenie srodka stosowanego do isnpreg- 20 nacji jest on bardzo korzystny pod wzgledem ekono¬ micznym.Przyklad: as Fluorokrzemian cynku 98,5 kg Urotropina 0,75 kg Kondensat kwasu oleinowego z kwasami aminokarboksylowymi z hydrolizatów bialka 0,75 kg so woda 4990 kg. 5669256692 Przykladowo srodek wedlug wynalazku sporza¬ dza sie nastepujaco: Do 4900 kg wody dodaje sie 98,5 kg fluorokrzemianu cynku, a nastepnie po wy¬ mieszaniu wprowadza sie 0,75 kg urotropiny i 0,75 kg kondensatu kwasu oleinowego z kwasami ami- nokarboksylowymi z hydrolizatów bialka i miesza sie roztwór az do chwili calkowitego rozpuszczenia wprowadzonych skladników. Srodkiem tym nasyca sie drewno metoda prózniowo-cisnieniowa stosujac podcisnienie okolo 600 mm Hg, cisnienie 7 atm i temperature roztworu 80° C. Wazna zaleta srodka wedlug wynalazku jest obnizenie korodujacego dzialania soli kwasu fluorokrzemowego na stal, co jest bardzo istotne przy impregnacji drewna w na- sycalniach prózniowo-cisnieniowych. PLPublished: 20.XII.1968 56692 IC. 38 h, 2/01 M1CP B UKO 27 k% p% Co-authors of the invention: Dr. Bronislaw Zyska, Dr. Wladyslaw Milkowski, Assoc. Wojciech Olpinski, Ph.D. Patent owner: Central Mining Institute, Katowice (Poland) A product for antifungal wood preservation The subject of the invention is an antifungal wood preservative based on fluorosilicic acid salts. The zinc salts used so far for the antifungal impregnation of wood , magnesium or ammonium fluorosilicic acid have antifungal properties, but they penetrate badly into the wood, which, when unsaturated inner layers are exposed, for example under the influence of bending or bending, causes rotting and complete loss of strength properties of wooden elements. Protropin and fatty acid products 2 Ammocarboxylic acids have so far been used as additives to aqueous solutions of chlorolignin sulfonic acid salts in order to eliminate the corrosive effect of these solutions and their self-acidification during storage. These additives did not improve the antifungal properties of the agent. The invention relates to an antifungal agent based on fluosilicic acid salts with improved antifungal properties and good penetration into wood. It has been found that a 1 to 33% aqueous solution containing from 90% to 99% 6% by weight of the salt of fluosilicic acid, 0.2% to 5% by weight of urotropin, and 0.2% to 5% by weight of fatty acid condensate with amino carboxylic acids, most preferably protein hydrolysates, effectively protects the wood against fungi and unexpectedly, it increases the toxic properties of the salts of fluosilicic acid. The role of the fatty acid condensate with amino carboxylic acids in the composition according to the invention is to increase the permeability of the fluorosilicic acid salt into the internal structure of wood-destroying fungi. The agent according to the invention penetrates perfectly into the wood and thus protects all internal layers of wood in an anti-fungal manner. This ftodide does not cause corrosion of steel devices * during preparation, storage and impregnation of wood with the agent. Due to the small amounts of urotropin additives introduced into the fluorosilicic acid salt and the condensate of fatty acids with aminocarboxylic acids, and the large dilution of the agent used for in-regulation, it is very advantageous in economic terms. Example: as zinc fluorosilicate 98.5 kg Urotropin 0.75 kg Oleic acid condensate with aminocarboxylic acids from protein hydrolysates 0.75 kg so water 4990 kg. 5,669,256,692 For example, the composition according to the invention is prepared as follows: 98.5 kg of zinc fluorosilicate are added to 4900 kg of water, and then after mixing, 0.75 kg of urotropine and 0.75 kg of oleic acid condensate with amino carboxylic acids are added. from the protein hydrolysates and the solution is mixed until the ingredients are completely dissolved. This agent saturates the wood with the vacuum-pressure method, using a vacuum of about 600 mm Hg, a pressure of 7 atm and a solution temperature of 80 ° C. An important advantage of the agent according to the invention is the reduction of the corrosive effect of fluorosilicic acid salt on steel, which is very important when impregnating wood with - vacuum-pressure filling plants.
