COMPOZIȚIE ANTIMICROBIANA SINERGICA CU EFECT FUNGICID SI INSECTICID PENTRU TRATAREA LEMNULUISYNERGIC ANTIMICROBIAL COMPOSITION WITH FUNGICIDE AND INSECTICIDE EFFECT FOR TREATMENT OF WOOD
Prezenta invenție se refera la o compoziție antimicrobiana cu efect fungicid si insecticid pentru tratarea lemnului, împotriva mucegairii si albastririi precum si împotriva insectelor care produc degradarea acestuia: termite, furnici, gandaci, viespi, cari si alte insecte daunatoare lemnului si a larvelor acestora.The present invention relates to an antimicrobial composition with fungicidal and insecticidal effect for the treatment of wood, against mold and bluish as well as against insects that cause its degradation: termites, ants, beetles, wasps, worms and other insects that are harmful to the wood and their larvae.
Compoziția antimicrobiana sinergica cu efect fungicid si insecticid pentru tratarea lemnului este o soluție limpede, ușor gălbuie sau roșiatica, cu densitatea 0,97 - 1,2 g/cc, miros specific si se utilizează in dispersie apoasa, de concentrație 0,6 - 2%, in funcție de procedeul de tratare si de durata de proiecție dorita, pentru protecția cherestelei de fag aburit, fag proaspăt debitat și rășinoase, stejar, a lemnului de construcții, a lemnului rotund de rășinoase proaspăt doborât în parchete și depozite si a buștenilor în exploatări forestiere, împotriva mucegăirii, albăstririi si atacului insectelor xilofage.Synergistic antimicrobial composition with fungicidal and insecticidal effect for wood treatment is a clear, slightly yellowish or reddish solution, with density 0.97 - 1.2 g / cc, specific odor and used in aqueous dispersion, concentration 0.6 - 2 %, depending on the treatment process and the desired projection duration, for the protection of steamed beech timber, fresh cut and resin beech, oak, construction timber, fresh wood round timber felled in parquet and storage and logs in logging, against mold, bluing and attack of xylophagous insects.
La alegerea componentilor pentru formularea unei compoziții antimicrobiene pentru tratarea lemnului, trebuie sa se tina cont de mai multi factori: eficacitatea biocida, consumul specific de substanța activa, gradul de penetrare in lemn, rezistenta la umiditate, pastrarea efectului de antiseptizare in timp, toxicitatea si ecotoxicitatea, care implica restricții de utilizare, costuri.When choosing the components for the formulation of an antimicrobial composition for wood treatment, several factors must be taken into account: the biocidal efficiency, the specific consumption of the active substance, the degree of penetration in the wood, the resistance to humidity, the preservation of the antiseptic effect over time, the toxicity and ecotoxicity, which involves usage restrictions, costs.
Se cunosc compoziții cu acțiune fungicida, avand la baza una sau mai multe substanțe active, anorganice, organometalice, organice, cum ar fi: arsenati de crom si cupru (CCA), acid boric precum si oxizi si săruri ale borului (borati), sulfați, oxizi si hidroxizi de cupru, cloruri si oxizi de zinc, săruri cuatemare de amoniu si cupru (ACQ), , naftenati de cupru, creozot, izotiazolone. săruri cuatemare de amoniu, carbamati, ditiocarbamati, triazoli sau amestecul acestora.Compositions with fungicidal action are known, based on one or more active substances, inorganic, organometallic, organic, such as: chromium and copper arsenates (CCA), boric acid as well as oxides and salts of boron (borates), sulphates , copper oxides and hydroxides, zinc chlorides and oxides, quaternary ammonium and copper salts (ACQ),, copper naphthenates, creosote, isothiazolones. quaternary ammonium salts, carbamates, dithiocarbamates, triazoles or mixtures thereof.
Se cunosc de asemenea compoziții insecticide pe baza de substanțe active anorganice, cum ar fi: tetraboratul de sodiu, acidul boric, tiocianatul de sodiu, tiocianatul de potasiu, arsenitul de sodiu, arsenitul de potasiu sau organometalice cum ar fi oleatul de cupru.Also known are insecticidal compositions based on inorganic active substances, such as: sodium tetraborate, boric acid, sodium thiocyanate, potassium thiocyanate, sodium arsenite, potassium arsenite or organometallics such as copper oleate.
Cea mai utilizata categorie de substanțe active insecticide sunt cele organice si anume piretroizii de sinteza, dintre care amintim alfa, beta teta si zeta-cipermetrin, bifentrin, deltametrin, dimetrin, permetrin.The most widely used category of insecticidal active substances are organic ones, namely synthetic pyrethroids, of which we mention alpha, beta theta and zeta-cypermethrin, bifentrin, deltamethrin, dimethrin, permethrin.
Tendința actuala in domeniul biocidelor este formularea acestora cu mai multe substanțe active, cu rol sinergie, ceea ce conduce la obținerea unui produs multifuncțional, un consum scăzut de substanța activa, minimizarea impactului asupra mediului înconjurător si sanatatii umane, precum si costuri mai scăzute. Sunt disponibile informații privind amestecuri 1 ί\*2 Ο 1 3 - Ο Ο 8 1 5 - Ο 7 -11- 2013 de substanțe active fungicide cum ar fi: propiconazol- tebuconazol- imidaclorprid, iodopropinilbutil carbamat (IPBC)- săruri cuaternare de amoniu, 4,5-dichloro-2-n-octyl-3isothiazolona (DCOIT)- IPBC.The current trend in the field of biocides is their formulation with more active substances, with synergistic role, which leads to obtaining a multifunctional product, low consumption of the active substance, minimizing the impact on the environment and human health, as well as lower costs. Information on mixtures 1 ί \ * 2 Ο 1 3 - Ο Ο 8 1 5 - Ο 7 -11- 2013 of fungicidal active substances such as: propiconazole-tebuconazole-imidachlorprid, iodopropinylbutyl carbamate (IPBC) - quaternary ammonium salts is available , 4,5-dichloro-2-n-octyl-3isothiazolone (DCOIT) - IPBC.
Astfel, in brevetul US 5 112 396 este prezentata o compoziție pentru tratarea lemnului împotriva mucegaiului, care este formulata pe baza de izotiazolona (preferate fiind 4,5-diclor2-n-octil-3-izotiazolona si 5-clor-2-metil-3-izotiazolona) si unul din următorii compuși sau amestecul lor: un compus policuatemar de amoniu, un agent de ingrosare sau dispersare, de preferința polialcoxilati ai alchilfenolilor (alchilfenoli polietoxilati), un compus cuaternar de amoniu simplu. Astfel, prin adaugarea la izotiazolona a unuia sau mai multora din compușii de mai sus, se micșorează pierderea preferențiala de izotiazolona din soluția de tratare, concentrația acesteia scazand mai puțin pe măsură tratării lemnului, cu efect favorabil asupra antiseptizarii lemnului si a consumului de izotiazolona. In funcție de compusul asociat izotiazolonei, pierderea acesteia in emulsia de tratare a lemnului scade de la 40-60% la 0,534%.Thus, a composition for treating wood against mold, which is formulated on the basis of isothiazolone (preferred being 4,5-dichloro-2-n-octyl-3-isothiazolone and 5-chloro-2-methyl-) is disclosed in US Pat. 3-isothiazolone) and one of the following compounds or mixtures thereof: a polycathematic ammonium compound, a thickening or dispersing agent, preferably polyalkoxylates of alkylphenols (polyethoxylated alkylphenols), a simple quaternary ammonium compound. Thus, by adding one or more of the above compounds to the isothiazolone, the preferential loss of the isothiazolone in the treatment solution is reduced, its concentration decreasing less as the wood is treated, with a favorable effect on the wood antisepticization and the consumption of isotiazolone. Depending on the compound associated with isothiazolone, its loss in the wood treatment emulsion decreases from 40-60% to 0.534%.
Aceste compoziții, deși rezolva o problema importanta, privind eficacitatea crescută a antiseptizarii la un consum mai scăzut de substanța activa, prezintă dezavantaje in raport cu tendințele contemporane, deoarece se refera totuși numai la efectul fungicid al acestor compoziții, totodată propunând pentru utilizare si substanțe restricționate de legislația comunitara ( alchilfenolii etoxilati), care sunt clasificați periculoși pentru sanatatea umana si mediu si nu se pot utiliza in produse antimicrobiene (biocide).These compositions, although they solve an important problem, regarding the increased effectiveness of the antisepticization at a lower consumption of the active substance, have disadvantages in relation to the contemporary trends, because they refer only to the fungicidal effect of these compositions, while proposing for use and restricted substances by Community legislation (ethoxylated alkylphenols), which are classified as hazardous to human health and the environment and cannot be used in antimicrobial products (biocides).
Problemele tehnice pe care le rezolva invenția consta in alegerea componentelor active si a coformulantilor, a raportului optim intre ele, care conduc la obținerea unei compoziții antimicrobiene sinergice sub forma de concentrat emulsionabil, utilizat in dispersie apoasa, la concentrații minime de substanțe active, eficace împotriva fungilor si insectelor xilofage, in special a mucegaiurilor si albastrelii, termitelor, furnicilor, gândacilor, viespilor, carilor si a larvelor acestora, care distrug lemnul.The technical problems to be solved by the invention consist in choosing the active components and the co-formulants, the optimal ratio between them, which leads to obtaining a synergistic antimicrobial composition in the form of emulsifiable concentrate, used in aqueous dispersion, at minimum concentrations of active substances, effective against xylophagous fungi and insects, especially molds and blueberries, termites, ants, cockroaches, wasps, chariots and their larvae, which destroy wood.
Substanțele active antimicrobiene (biocide) utilizate conform invenției, au o mare rezistenta la spalarea cu apa, deci lemnul tratat va avea o protecție îndelungata; de asemenea riscul antrenării lor cu apa atmosferica si pătrunderea in sol si ape subterane este minim. Compoziția antimicrobiana sinergica cu efect fungicid si insecticid pentru tratarea lemnului conține substanțe active cu funcții multiple, astfel, sarea cuatemara de amoniu, pe langa efectul antimicrobian, are si rol de agent activ de suprafața de tip cationic, potenteaza activitatea fungicida a DCOIT si cea insecticida a piretroizilor, mărește adancimea de penetrare in lemn, împiedica consumul preferențial al izotiazolonei in soluția de tratare siThe active antimicrobial (biocidal) substances used according to the invention, have a high resistance to washing with water, so the treated wood will have a long protection; also the risk of their entrainment with atmospheric water and penetration into soil and groundwater is minimal. The synergistic antimicrobial composition with fungicidal and insecticidal effect for wood treatment contains active substances with multiple functions, thus, the quaternary ammonium salt, besides the antimicrobial effect, also has the role of active agent of the cationic type surface, enhances the fungicidal activity of DCOIT and insecticide. of pyrethroids, increases the depth of penetration into wood, prevents preferential consumption of isothiazolone in the treatment solution and

stabilizează emulsia, prin efectul tensioactiv. De asemenea si combinația DCOIT- piretroizi actioneaza sinergie, reducând consumul de substanța activa fungicida si insecticida. Componentele active ale compoziției antimicrobiane sinergice cu efect fungicid si insecticid pentru tratarea lemnului, conform invenției, au eficacitate ridicata la un consum redus si sunt incluse in lista substanțelor active pentru tratarea si conservarea lemnului evaluate sau aflate in evaluare al nivel comunitar, deci pot fi puse legal pe piața. De asemenea emulgatorul utilizat este biodegradabil, cu impact minim asupra mediului.stabilizes the emulsion through the surfactant effect. Also the combination DCOIT-pyrethroids acts synergistically, reducing the consumption of the active substance fungicide and insecticide. The active components of the synergistic antimicrobial composition with fungicidal and insecticidal effect for the treatment of wood, according to the invention, have a high efficiency at reduced consumption and are included in the list of active substances for treating and preserving the wood evaluated or under evaluation at Community level, so they can be put legally on the market. Also the emulsifier used is biodegradable, with minimal impact on the environment.
