Description

TEHNIKAVALDKOND TECHNOLOGY FIELD

Leiutis kuulub veepõhiste tuletõkkevahendite ja tulekindluse suurendamise eesmärgil kasutatavate orgaaniliste ainete immutusvahendite valdkonda. The invention belongs to the field of water-based fire retardants and impregnation agents for organic substances used for the purpose of increasing fire resistance.

TEHNIKA TASE STATE OF THE ART

Tuntud on US4804482, mis kirjeldab sidrunhappe vesilahust, milles sidrunhapet on 300-350 g/l ning Na- ja K-ioonide ekvimolaarne suhe on 0,6-1,0:100, kusjuures Na-ioonid saadakse naatriumkarbonaadist ning K-ioonid kaaliumkarbonaadist. Selline lahus sobib tulekustutusvahendiks ning orgaaniliste materjalide töötlemiseks neile tulekindluse andmiseks. US4804482 is known, which describes an aqueous citric acid solution in which citric acid is 300-350 g/l and the equimolar ratio of Na and K ions is 0.6-1.0:100, whereby Na ions are obtained from sodium carbonate and K ions from potassium carbonate. Such a solution is suitable as a fire extinguishing agent and for treating organic materials to give them fire resistance.

Tuntud on US2005116193, mis kirjeldab segu, mis sisaldab 10-50 kaaluprotsenti tuldkustutavat komponenti, 3-15 kaaluprotsenti orgaanilist hapet, 0,01 kuni 5 kaaluprotsenti pindaktiivset ainet ning vett 100 kaaluprotsenti. Samuti kirjeldatakse segu valmistamise meetodit, mille kohaselt lahustatakse 10-50 kaaluprotsenti tuldkustutavat komponenti vees, milles lahustatakse 3-15 kaaluprotsenti orgaanilist ainet ning seejärel 0,01 kuni 5 kaaluprotsenti pindaktiivset ainet ning lastakse segul seista vähemalt 24-48 tundi segu stabiliseerimiseks. Tuldkustutavaks komponendiks võib paljude teiste komponentide hulgas olla kaaliumkarbonaat või uurea (karbamiid); selle kogus alla 10 kaaluprotsendi toob kaasa segu halvad tuldkustutavad omadused; üle 50 kaaluprotsendi põhjustab sadestist segus. Orgaaniliseks happeks võib olla paljude hapete seas sidrunhape 3-15 kaaluprotsenti - kui sidrunhappe kogus on sellest vahemikust väljas, ei ole segu neutraalne.Seda võib pidada tehnika tasemest tuntud kõige lähedasemaks lahenduseks. Üllatavalt saab samade või paremate tuldtõrjuvate ja -tõkestavate omadustega veepõhise segu, milles sidrunhappe kogus võrreldes kaaliumkarbonaadiga on sama või suurem. US2005116193 is known, which describes a mixture containing 10-50% by weight of a fire extinguishing component, 3-15% by weight of an organic acid, 0.01 to 5% by weight of a surfactant and 100% by weight of water. It also describes a method of preparing the mixture, according to which 10-50% by weight of a fire extinguishing component is dissolved in water, in which 3-15% by weight of an organic substance is dissolved and then 0.01 to 5% by weight of a surfactant is dissolved and the mixture is allowed to stand for at least 24-48 hours to stabilize the mixture. The fire extinguishing component may be potassium carbonate or urea (carbamide), among many other components; its amount below 10% by weight leads to poor fire extinguishing properties of the mixture; above 50% by weight causes precipitation in the mixture. The organic acid may be citric acid, among many acids, in the range of 3-15% by weight - if the amount of citric acid is outside this range, the mixture is not neutral. This can be considered the closest solution known from the prior art. Surprisingly, a water-based mixture with the same or better fire-retardant and flame-retardant properties is obtained in which the amount of citric acid compared to potassium carbonate is the same or higher.

Leiutise neljanda teostamise näite kohaselt valmistatakse kompositsioon, mille koostis on järgmine: According to a fourth embodiment of the invention, a composition is prepared having the following composition:

kaaliumkarbonaat 18,5 massiosa; sidrunhape 20 massiosa; karbamiid 10 massiosa; ja vesi 100 massiosa. potassium carbonate 18.5 parts by weight; citric acid 20 parts by weight; urea 10 parts by weight; and water 100 parts by weight.

Kompositsioon valmistatakse eelistatult järgmiselt: The composition is preferably prepared as follows:

185 g kuni 200 g pulbrilist sidrunhapet lahustatakse 400 ml vees, 185 g kuni 200 g pulbrilist kaaliumkarbonaati lahustatakse 400 ml vees, 80 g kuni 100 g karbamiidi lahustatakse 200 ml vees ning saadud vesilahused segatakse kokku. 185 g to 200 g of powdered citric acid are dissolved in 400 ml of water, 185 g to 200 g of powdered potassium carbonate are dissolved in 400 ml of water, 80 g to 100 g of urea are dissolved in 200 ml of water and the resulting aqueous solutions are mixed together.

Kompositsiooni võib valmistada ka järgmiselt: The composition can also be prepared as follows:

185 g kuni 200 g pulbrilist sidrunhapet ning kaaliumkarbonaati segatakse ning valmis pulber lahustatakse 1000 ml vees ning lisatakse 80 g-100 g karbamiidi. 185 g to 200 g of powdered citric acid and potassium carbonate are mixed and the finished powder is dissolved in 1000 ml of water and 80 g-100 g of urea is added.

Valmis kompositsiooni lisatakse soovitud koguses kasulikke lisaaineid, näiteks 10-15 g etanooli või metanooli ühe liitri lahuse kohta, 2-3 g raudfosfaati ühe liitri lahuse kohta ja 1-2 massiprotsenti boorhapet. The desired amount of beneficial additives is added to the finished composition, for example 10-15 g of ethanol or methanol per liter of solution, 2-3 g of iron phosphate per liter of solution, and 1-2% by weight of boric acid.

Kompositsiooni tuldtõkestavad omadused on tingitud sellest, et temperatuuri tõusmisel üle 175°C sidrunhape laguneb akoniithappeks ning laguneb edasi veeks ja süsinikdioksiidiks. The fire-retardant properties of the composition are due to the fact that when the temperature rises above 175°C, citric acid decomposes into aconitic acid and further decomposes into water and carbon dioxide.

Kompositsioon sobib kasutamiseks puiduimmutusvahendina tulekindluse tõstmiseks, samuti puidu, puidust toodetud materjalide (paber, papp), kanga jms materjali tulekindluse tõstmiseks. Kompositsiooniga immutatud puit vastab tulekindlusklassile A2, B, sl ja d0. Puidu pinna kuumutamisel hakkab töödeldud pinna pealmine kiht söestuma ja paisub („mullitab") ning takistab sellega tule edasist levikut materjali sisse. The composition is suitable for use as a wood impregnation agent to increase fire resistance, as well as to increase the fire resistance of wood, wood-based materials (paper, cardboard), fabric, etc. Wood impregnated with the composition corresponds to fire resistance classes A2, B, sl and d0. When the surface of the wood is heated, the top layer of the treated surface begins to char and expand ("bubble"), thereby preventing the further spread of fire into the material.

Kompositsioon sobib kasutamiseks ka tuletõkkevahendina metsa- ja kulupõlengute jms kahjutule leviku piiramiseks. Sel juhul kaetakse kompositsiooniga põlenguala ümbritsev ala, näiteks maapind, puud, ehitised, et tuli ei saaks põlengualalt edasi tungida. The composition is also suitable for use as a fire retardant to limit the spread of forest and brush fires, etc. In this case, the composition covers the area surrounding the fire area, such as the ground, trees, and buildings, so that the fire cannot spread further from the fire area.

Eeltoodud ainete kogused on optimeeritud. Kaaliumkarbonaadi koguse vähendamine lähteainete hulgas teiste lähteainete koguse jäämisel samaks pakutud vahemikust allapoole halvenevad kompositsiooni tulekindlust andvad omadused. Kaaliumkarbonaadi koguse suurendamine pakutud vahemikust ülespoole teiste lähteainete koguse jäämisel samaks suureneb kompositsiooni tihedus, imendumine materjali väheneb ning seeläbi halvenevad tulekindlust andvad omadused. Sidrunhappe koguse vähendamine halvendab samuti tulekindlust andvaid omadusi, sh väheneb kompositsiooni paisumisefekt (mullitamisefekt) kuumutamisel. Sidrunhappe koguse suurendamisel suureneb tihedus ning toote pinnale võib tekkida valge katt. Karbamiidi koguse vähendamisel halveneb lahustuvus ning kompositsiooni imendumine materjali. Karbamiidi koguse suurendamine toob taas kaasa tiheduse suurenemise ning sellega imendumise halvenemise, aga samuti võib kompositsioon ning seetõttu ka töödeldud pind omandada kollaka värvuse (leiutisekohases lähteainete vahemikus on kompositsioon värvitu). The amounts of the above substances have been optimized. Reducing the amount of potassium carbonate among the starting materials, while the amounts of other starting materials remain the same, below the proposed range, will worsen the fire resistance properties of the composition. Increasing the amount of potassium carbonate above the proposed range, while the amounts of other starting materials remain the same, will increase the density of the composition, the absorption of the material will decrease, and thus the fire resistance properties will deteriorate. Reducing the amount of citric acid will also worsen the fire resistance properties, including the expansion effect (bubbling effect) of the composition upon heating will decrease. Increasing the amount of citric acid will increase the density and a white coating may form on the surface of the product. Reducing the amount of urea will worsen the solubility and absorption of the composition by the material. Increasing the amount of urea will again lead to an increase in density and thus deterioration of absorption, but the composition and therefore the treated surface may also acquire a yellowish color (in the starting material range according to the invention, the composition is colorless).
