Ammoniumvapaa lämmöneristeAmmonium-free thermal insulation
Keksinnön kohteena on palosuojattu lämmöneriste, joka käsittää 80-95 paino-% keräyspaperia eristeaineena ja 5-15 paino-% jauhemaista palonestoainetta, jolloin pa-lonestoaine ei sisällä booria eikä booria sisältäviä yhdisteitä.The invention relates to a flame retardant thermal insulation comprising 80-95% by weight of recycled paper as an insulating material and 5-15% by weight of a powder flame retardant, wherein the flame retardant does not contain boron or boron containing compounds.
Energiatehokkuuden parantamiseksi rakennuksissa on viime vuosina kiinnitetty erityistä huomiota hyvään lämmöneristykseen. Lämmöneristyksessä käytetään epäorgaanisia raaka-aineita, kuten lasi-ja kivivillaa, tai orgaanisia materiaaleja, kuten sty-roporia ja lampaanvillaa, tai selluloosapitoisia materiaaleja, kuten sahanpurua, korkkia tai huopaa. Kierrätysprosesseista saadaan kuidutettua sanomalehtipaperia, jota käytetään lämmöneristysaineena. Keräyspaperista tehtyjen eristeiden haittapuolena on niiden palavuus ja korkea syttymisvaara. Tästä syystä keräyspaperista valmistettujen palosuojattujen lämmöneristeiden pitää olla varustettuja niin, että ne täyttävät tällaiselle tuotteelle asetetun palosuojaluoki-tuksen vaatimukset. Palonestoaineena käytetään nykyisin pääasiassa boorisuoloja. Ne on kuitenkin luokiteltu lisääntymismyrkyllisiksi, ja ne on otettu Reach-asetuksen kandidaattilistalle merkinnällä ”subject of very high concern”. Ne katsotaan siksi ei-toivotuiksi ekologisessa tuotteessa, kuten vaihtoehtoisessa eristeessä, jossa on keräyspaperista peräisin olevia selluloosahiutaleita. Tähän saakka keräyspaperin vaihtoehtoisena palonestoaineena on siksi käytetty ammoniusuoloja. Toinen tärkeä rajoitus seuraa nyt uudesta, 23.6.2016 päivätystä EU-asetuksesta 2016/1017, joka kieltää ammoniumsuolojen käytön selluloosaeris-teiden palonestoaineina.In order to improve the energy performance of buildings, special attention has been paid in recent years to good thermal insulation. Thermal insulation uses inorganic raw materials such as glass and rock wool, or organic materials such as styropor and sheep wool, or cellulosic materials such as sawdust, cork or felt. Recycling processes yield pulp newsprint, which is used as a heat insulating material. Drawbacks made of recycled paper have the drawback of their flammability and high risk of ignition. For this reason, fire-retardant thermal insulators made from recycled paper must be equipped to meet the requirements for fire protection classification for such a product. Today, boron salts are mainly used as flame retardants. However, they have been classified as reproductive toxicants and have been included on the candidate list for REACH under the heading 'subject of very high concern'. They are therefore considered undesirable in an organic product such as an alternative dielectric with cellulose flakes from recycled paper. Until now, therefore, ammonium salts have been used as an alternative flame retardant in recycled paper. Another important restriction now follows from the new EU Regulation 2016/1017 of 23 June 2016, which prohibits the use of ammonium salts as flame retardants in cellulose isolates.
Suurimpaan osaan käytetyistä, perinteisistä palonestoaineista pitää niiden kemiallisen koostumuksen vuoksi suhtautua kriittisesti siihen, mitä tulee niiden myrkyllisyyteen, ympäristövaikutuksiin sekä hajoavuuteen.Most of the conventional flame retardants used, due to their chemical composition, need to be critical of their toxicity, environmental effects and degradability.
Tehtävänä oli näin ollen valmistaa sellainen ympäristöystävällinen palosuojattu lämmöneriste keräyspaperista, että vältytään näiltä ennalta mainituilta haitoilta, ja joka on erityisesti toksikologisesti harmiton ja lain sallima.The task, therefore, was to make an environmentally friendly flame retardant heat-insulating material that avoids the aforementioned disadvantages, and is particularly toxicologically harmless and permitted by law.
Keksinnönmukaisesti tämä tehtävä ratkaistaan suojavaatimuksen 1 mukaisella läm-möneristeellä.According to the invention, this object is solved by the thermal insulation according to claim 1.

On eri perliittilajeja. Yhtäältä on niin sanottua raakaperliittiä, joka on peräisin vulkaanisesta laavasta, joka on kosketuksessa veteen (vesihöyryyn) jäähtynyt erittäin nopeasti valtavassa paineessa. Se kuuluu ryoliittien ryhmään, jota nimitettiin ennen myös kvartsiporfyyriksi, ja lukeutuu kivilajeihin. Raakaperliitti on alumiinisilikaattia, ja siinä on yli 70 prosenttia, eli epätavallisen suuri osuus piidioksidia. Toisaalta on paisutettua perliittiä. Raakaperliitin tilavuuspaino on n. 900-1000 kg/m3, hehkuttamalla se n. 800-1000 °C:seen, se paisuu 15-20-kertaiseksi alkutilavuuteensa nähden, ja sen tilavuuspaino on silloin 50-100 kg/m3. Keksinnönmukaisesti raa’at ja paisutetut periiittilajit sopivat yhtä hyvin käytettäviksi palonestoaineina.There are different types of perlite. On the one hand, there is the so-called crude perlite, which originates from volcanic lava, which, in contact with water (water vapor), has cooled very rapidly under enormous pressure. It belongs to the group of ryolites, formerly also called quartz porphyry, and belongs to the rocks. Crude perlite is aluminum silicate and contains more than 70%, which is an unusually high proportion of silica. On the other hand, there is expanded perlite. The crude perlite has a bulk density of about 900-1000 kg / m3, when annealed to about 800-1000 ° C, expands 15-20 times its initial volume and then has a bulk density of 50-100 kg / m3. According to the invention, the crude and expanded perite species are equally suitable for use as flame retardants.
Perliitin tyypillinen kemiallinen koostumus on:The typical chemical composition of perlite is:
Keksinnönmukaisesti perliitin synergisinä lisäaineina käytetään seuraavia yhdisteitä: - Fosforipitoiset yhdisteetAccording to the invention, the following compounds are used as synergistic additives for perlite: - Phosphorous compounds
Voidaan käyttää sekä epäorgaanisia että orgaanisia fosforiyhdisteitä tai molempien sekoituksia. Esimerkkejä keksinnönmukaisen palonestoaineen fosforipitoisista lisäaineista ovat: mononatriumfosfaatti, dinatriumfosfaatti, trinatriumfosfaatti, monokaliumfosfaatti, dikaliumfosfaatti, trikaliumfosfaatti, monokalsiumfosfaatti, dikalsium-fosfaatti, trikalsiumfosfaatti, monomagnesiumfosfaatti, dimagnesiumfosfaatti, dinat-riumdifosfaatti, trinatriumtridifosfaatti, tetranatriumdifosfaatti, tetrakaliumdifosfaatti, dikalsiumdifosfaatti, kalsiumdivetyfosfaatti, pentanatriumtrifosfaatti, pentakaliumtri-fosfaatti, natriumpolyfosfaatti, kaliumpolyfosfaatti, natriumkalsiumpolyfosfaatti, kal-siumpolyfosfaatti, rautafosfaatti, magnesiumfosfaatti, alumiinifosfaatti. Erityisen edullisesti kalsium-ja magnesiumfosfaatit.Both inorganic and organic phosphorus compounds or mixtures of both may be used. Examples of the inventive flame retardant phosphorus-containing additives include: monosodium phosphate, disodium phosphate, trisodium phosphate, monopotassium phosphate, dipotassium phosphate, tripotassium phosphate, monocalcium phosphate, dicalcium phosphate, tricalcium phosphate, MONOMAGNESIUM, dimagnesiumfosfaatti, Dinat-riumdifosfaatti, trinatriumtridifosfaatti, tetrasodium diphosphate, TETRAPOTASSIUM, Dicalcium dihydrogen phosphate, Pentasodium, pentakaliumtri-phosphate , sodium polyphosphate, potassium polyphosphate, sodium calcium phosphate, calcium phosphate, iron phosphate, magnesium phosphate, aluminum phosphate. Particularly preferred are calcium and magnesium phosphates.
Fosforipitoiset yhdisteet toimivat kiinnitetyn, hiillytetyn pintakerroksen muodostamiseksi fosforiyhdisteistä. Lisäksi ne keskeyttävät tietyissä tapauksissa palamisprosessin radikaalin ketjumekanismin kaasufaasin sisällä. Lämpöhajoamisessa palon-estoaine muuttuu fosfori hapoksi, ja pyrolyysillä aineesta poistetaan vettä. Näin po-lyfosforihapoista ja hiilestä muodostuu suojakerros. - Typpipitoiset fosforiyhdisteetPhosphorous compounds act to form a fixed, carbonized surface layer of phosphorus compounds. In addition, in certain cases, they interrupt the combustion process within the gas phase of the radical chain mechanism. Upon thermal decomposition, the fire retardant is converted to phosphoric acid and pyrolysis removes water from the substance. Thus a protective layer is formed between the polyphosphoric acids and the carbon. - Phosphorus compounds containing nitrogen
Erityisen soveltuviksi ovat osoittautuneet orgaaniset fosforiyhdisteet, jotka ovat sekä typpipitoisia että fosfaattipitoisia. Näihin luetaan erityisesti: ureafosfaatti, melamiini-fosfaatti, melamiinipolyfosfaatti, melamiinisyanuaraatti, guanidiinifosfaatti. - Typpipitoiset yhdisteetOrganophosphorus compounds which are both nitrogenous and phosphate-containing have proved to be particularly suitable. These include, in particular: urea phosphate, melamine phosphate, melamine polyphosphate, melamine cyanurate, guanidine phosphate. - Nitrogenous compounds
Soveltuvia ovat myös orgaaniset yhdisteet, jotka ovat vain typpipitoisia. Näihin luetaan erityisesti: melamiini, guanidiini, urea ja 1-syanoguanidiini, bentsoguanidiini. Nämä yhdisteet voivat vaikuttaa kaasufaasissa hajottamalla inerttejä kaasuja (ammoniakki, typpi) tai saada kondensaatioreaktioiden ansiosta aikaan kiinteän faasin hiiltymistä.Organic compounds which are nitrogen-only are also suitable. These include, in particular: melamine, guanidine, urea and 1-cyanoguanidine, benzoguanidine. These compounds can act in the gas phase by decomposing inert gases (ammonia, nitrogen) or by condensation reactions to cause solid phase carbonation.
Keksinnönmukaisesti myös seuraavat aineet ovat osoittautuneet synergisesti vaikuttaviksi lisäaineiksi: magnesiumsulfaatti, natriumbikarbonaatti, lysiinisulfaatti, kalsiumkarbonaatti, natriumkarbonaatti, natriumsitraatti, alumiinihydroksidi, magnesiumhydroksidi, sinkki-sulfidi, natriumfosfinaatti, magnesiumkloridi, kalsiumsulfaatti, kalsiummagnesium-karbonaatti. Nämä lisäaineet vaikuttavat endotermisen hajoamisen energiankulutukseen, esimerkiksi sitoutunutta vettä höyrystämällä, minkä ansiosta materiaali jäähtyy, tai vapauttamalla liekkejä tukahduttavia kaasuja (esim. hiilidioksidia).According to the invention, the following substances have also been found to be synergistically active additives: magnesium sulfate, sodium bicarbonate, lysine sulfate, calcium carbonate, sodium carbonate, sodium citrate, aluminum hydroxide, magnesium hydroxide, zinc sulfide, calcium phosphinate, sodium phosphinate, sodium phosphate. These additives affect the energy consumption of endothermic decomposition, for example by evaporating the bound water, which causes the material to cool, or by releasing flame-retardant gases (e.g. carbon dioxide).
Synergisiä lisäaineita käytetään erikseen tai eri lisäaineiden sekoituksena ja myös eri ryhmistä peräisin olevien lisäaineiden sekoituksena.Synergic additives are used alone or as a mixture of different additives and also as additives from different groups.
Keksinnönmukaista lämmöneristettä on tarkasteltava ympäristöystävällisenä uudistuksena, jossa ei lisäksi ole ammoniumsuoloja ja jolla on parempi tehokkuusaste kuin tekniikan tason mukaisilla palosuojatuilla lämmöneristeillä.The thermal insulation according to the invention has to be considered as an environmentally friendly reform, which is additionally free of ammonium salts and which has a higher degree of efficiency than the prior art fire-resistant thermal insulation.
Palonestoaine voidaan tunnettujen menetelmien avulla levittää keräyspaperin päälle. Palonestoaine voidaan esimerkiksi kuiduttamisen yhteydessä sekoittaa keräyspaperista tehdyn eristeen kanssa vastaavissa myllyissä. Palonestoaine on tässä tapauksessa kuivan jauheen muodossa.The flame retardant can be applied to the recycled paper by known methods. For example, flame retardant may be mixed with recycled paper dielectric in respective mills during defibration. The flame retardant in this case is in the form of a dry powder.
Yllättäen on todettu, että käyttämällä perliittiä (vulkaaninen kivilaji) voidaan saavuttaa epätavallisen voimakastehoinen palonesto keräyspaperista tehtyihin eristeisiin. Perliitti on luonnostaan palamatonta ja haitta-aineetonta vulkaanista kiveä, joka syntyy, kun nestemäinen magma joutuu hapettomasti kosketuksiin veden kanssa. Erilaisten synergisesti vaikuttavien lisäaineiden soveltuvan yhdistelyn avulla palo-nesto-ominaisuuksia voidaan parantaa vielä lisää. Tämän ansiosta voidaan saavuttaa parempi ja ympäristöystävällisempi palonnesto, kuin mikä on tunnettua tekniikan tasosta. Se oli erittäin yllättävää, koska perliittiä käytetään pääasiallisesti ennen kaikkea seuraavilla käyttöalueilla, rakennusteollisuudessa äänenvaimennuksessa tai kevytrakenteiden valmistuksessa, elintarviketeollisuudessa suodatusmateriaa-lina oluen, virvoitusjuomien ja ruokaöljyn valmistuksessa, lääketeollisuudessa antibioottien suodatuksessa, maataloudessa maaperän parantamisessa, lietelannan käsittelyssä, kasvinsuoja-aineena ja ympäristönsuojelussa öljysaasteiden keräämisessä veden pinnalta ja uima-altaiden veden suodattamisessa. Ei ollut odotettavissa, että perliitti soveltuisi erinomaisesti käytettäväksi keräyspaperista tehdyissä eristeissä.Surprisingly, it has been found that the use of perlite (a volcanic rock type) can achieve abnormally high flame retardancy in recycled paper insulators. Perlite is a naturally non-combustible and harmless volcanic rock that occurs when liquid magma comes into contact with water without oxygen. By suitable combination of various synergistically active additives, the fire-liquid properties can be further improved. This allows better and more environmentally friendly fire prevention than is known in the art. It was very surprising, since perlite is mainly used in the following applications, in the construction industry for silencing or lightweight construction, in the food industry as a filtering material for beer, in soft drinks and cooking oil, in the pharmaceutical industry for antibiotic filtration, in agriculture, from the surface and filtering water from swimming pools. Perlite was not expected to be ideally suited for use in recycled paper insulators.
Perliittien lisäetuina ovat niiden verrattain pienet hankintakustannukset ja ehtymätön esiintyvyys ja syntyminen tulivuoriaktiivisuuden ansiosta koko maailmassa. Se, että kyseessä on puhtaan mineraalinen raaka-aine, on ympäristöystävällistä ja kestävää, ja sopii sen ansiosta erinomaisesti kierrätysprosessista peräisin oleviin eristeisiin.Perlites have the added benefit of their relatively low cost of acquisition and inexhaustible incidence and emergence of volcanic activity worldwide. Being a pure mineral raw material, it is environmentally friendly and durable and makes it ideal for insulations from the recycling process.

Resistance test
Tulenkestävyystestit suoritettiin tulenkestävyyskoestuslaitteessa DIN ISO 11925-2:n mukaisesti rakennusaineluokan B2 (normaalisti syttyvä) määrittämiseksi. Läm-möneristeet, joissa on palonestoyhdisteitä A-J, laitettiin testipidikkeeseen (pieni kori irtonaisia aineita varten) ja kiinnitettiin polttolaatikossa pystysuorasti kiinnityslaittee-seen. Tämän jälkeen 45 asteen kulmassa taivutetussa polttimessa pidettiin tulta 15 sekunnin ajan. Mitattiin hiiltymismatka (palamiskeila, hiiltynyt materiaali) sekä mahdollinen kyteminen tai savuaminen. Testi katsottiin läpäistyksi, jos 15 cm:n hiiltymis-matkaa ei ylitetty. Lisäksi tarkasteltiin kytemistä ja savuamista, tällä hetkellä ei kuitenkaan ole mitään parametreja, joita vaadittaisiin rakennusaineluokan B2 testin läpäisemiseksi.The fire resistance tests were carried out in a fire tester in accordance with DIN ISO 11925-2 to determine the building material class B2 (normally flammable). Thermal insulators containing flame retardant compounds A-J were placed in a test holder (small basket for loose substances) and mounted vertically in a fixture in the combustion box. The torch was then inclined at a 45-degree angle for 15 seconds. The carbonization distance (combustion beam, charred material) and possible ignition or smoke were measured. The test was considered passed if the 15 cm carbonation distance was not exceeded. In addition, combustion and smoke were considered, but at present there are no parameters that would be required to pass the B2 class building material test.
Tulokset on tiivistetty seuraavaan taulukkoon.The results are summarized in the following table.
Näin ollen kaikki keksinnönmukaiset ammoniumittomat perliittipohjaiset palones-tosekoitukset voivat saavuttaa vaaditun luokittelun rakennusaineluokkaan B2.Thus, all ammonium-free perlite-based fire-retardant blends of the invention can achieve the required classification as building material class B2.
