Abstract

Sposób wytwarzania ekologicznych polioli z odpadu po transestryfikacji olejów roślinnych, w którym odpad ogrzewa się do temperatury w przedziale od 160 do 240°C, korzystnie od 175 do 185°C pod obniżonym ciśnieniem, oddestylowując części lotne, aż do momentu zaprzestania wydzielania się skroplin oraz otrzymania produktu o liczbie hydroksylowej od 400 do 1200 mg KOH/g. Następnie dodaje się w nadmiarze kwasy tłuszczowe z grupy: estry metylowe kwasów tłuszczowych, oleje roślinne w postaci oleju rzepakowego i/lub oleju rycynowego i/lub oleju talowego i/lub produkty destylacji oleju talowego i/lub oleju lnianego i miesza się w temperaturze od 160 do 200°C, korzystnie od 175 do 185°C do momentu ustalenia się liczby hydroksylowej, po czym mieszaninę schładza się do temperatury nieprzekraczającej 100°C, a następnie zakwasza się kwasem protonowym do pH od 4,5 do 9, po czym całość ogrzewa się pod obniżonym ciśnieniem do temperatury w przedziale od 100 do 120°C do momentu zaprzestania wydzielania się wody. Przedmiotem wynalazku jest również sposób wytwarzania pianek poliuretanowych z użyciem polioli uzyskanych sposobem według wynalazku. Pianki dodatkowo zawierają substancje zmniejszające ich palność.A method of producing organic polyols from waste after transesterification of vegetable oils, in which the waste is heated to a temperature in the range from 160 to 240 ° C, preferably from 175 to 185 ° C under reduced pressure, by distilling off the volatile components until the condensation ceases and obtaining a product with a hydroxyl number between 400 and 1200 mg KOH / g. Then fatty acids from the group: fatty acid methyl esters, vegetable oils in the form of rapeseed oil and / or castor oil and / or tall oil and / or tall oil and / or linseed oil distillation products are added and mixed at a temperature of from 160 to 200 ° C, preferably from 175 to 185 ° C until the hydroxyl number is established, after which the mixture is cooled to a temperature not exceeding 100 ° C, and then acidified with protic acid to a pH of 4.5 to 9, and then the whole is heated under reduced pressure to a temperature in the range of 100 to 120 ° C until the release of water stops. The invention also relates to a method for producing polyurethane foams using polyols obtained by the process of the invention. The foams additionally contain flame retardant substances.
