Description
W technice w wielu wypadkach stosu¬ je sie sztuczne masy twarde, sporzadzone z subsitancyj organicznych i nieorganicz¬ nych, które przewaznie otrzymuja sie za- pomoca stlaczania na goraco, przyczem jako spoiwo sluza smoly naturalne, jak np. szellak, lub tez smoly otrzymywane sztucz¬ nie przez zageszczenie fenolu z aldehyda¬ mi, jak np. bakelity lub podobne substan¬ cje.Smoly naturalne topniejace maja spe¬ cjalne lecz ograniczone zastosowanie, jak naprzyklad przy fabrykacji plyt do gramo¬ fonów, a takze w pewnych galeziach elek¬ trotechniki. Smoly zas nie topniejace, o- trzymywane ze zgeszczonego fenolu z al¬ dehydami, maja duze zastosowanie, lecz w wielu wypadkach stlaczanie na goraco by¬ wa uciazliwe, albowiem ze strony mecha¬ nicznej trudnosci przedstawia urzadzenie prasy lub matrycy^ ze strony zas chemicz¬ nej wykazuje te we de to, ze nie pozwa¬ laja w pewnych wypadkach doprowadzac potrzebne domieszki, jak np. latwo plynne smoly, oleje mineralne i podobne substan¬ cje.W celu usuniecia stlaczania na goraco czyniono rózne próby; stosowano lakiery zasadowe przy zgeszczaniu i napelnianie substancjami twardemi, lecz wszystkie te próby nie daly dobrych rezultatów, albo¬ wiem proces przyrzadzania masy do wy¬ tlaczania na zimno jest zbyt dlugi, a przy nastepnem nagrzewajniu wyroby traca swój wyglad zewnetrzny.Wynalazca ustalil, ze mozna otrzymac pomyslne wyniki zapomoca stlaczania na. zimno z dodaniem najrozmaitszych orga-\ niczny eh i nieorganicznych skladników, j e- ali zastosowac sposób kondensowania fenolu i aldehydu pod warunkiem kondensowania kwasnego, przyczem w pierwszem stadjum otrzymuje sie produkty majace wyglad smól z czesciowa (niezupelna) iloscia for^ maliny. Produkty te zgeszczenia mieszaja sie z formalina i domieszkami, jakie chce sie wprowadzic w obecnosci kwasów sulfc- naftowych, siarkowanych tluszczów lub tez siarkowanej mieszaniny glicerydów z we¬ glowodorami aromatyeznemi, 'jak równiez i z ich pochodneml Przyklad, 100 czesci smoly fenolowej otrzymanej przy zgeszczeniu z 60 czescia¬ mi formaliny 40% i 5 czesciami kwasu sol¬ nego, 20 czesci oleju rzepakowego siarko¬ wanego, 30 czesci sulfokwasów naftowych, 40 czesci formaliny 40%, 100 czesci sunoly galzowej, 80 czesci glinki porcelanowej (kaoliny), 20 czesci azbestu.W tej mieszaninie, przy nagrzewaniu najprzód mieszaja sie smola; fenolowa, smo¬ la gazowa, siarkowany olej rzepakowy, kwasy sulfonaftowe, poczem mieszanine chlodzi sie i wprowadza sie formaline, na¬ stepnie zagniata sie glinke porcelanowa i azbest i pozostawia sie mase dopóty, az dojdzie do stanu, w jakim ja mozna stla- czac. Otrzymane przedmioty pozostawia sie od 10 do 12 godzin w 30° do 40° C, i 3 do 4 godzin w 80—90° C; na tern pro¬ ces polimeryzacji konczy sie- Otrzymana w ten sposób mase mozna stosowac w elektrotechnice do wyrobu gu¬ zików lub plyt gramofonowych, w przemy¬ sle chemicznym i do izolacji cieplnej. PLIn many cases, in the art, artificial hard masses made of organic and inorganic substances are used, which are usually obtained by hot steaming, and natural tars, such as shellac, or artificial tar are used as binder. Not by concentrating the phenol with aldehydes, such as bakelites or similar substances. Natural melting smams have a special but limited use, for example in the fabrication of gramophone records and also in some branches of electrical engineering. However, non-melting tars, made of condensed phenol with aldehydes, are of great use, but in many cases hot plowing was difficult, because the press or matrix equipment presents a mechanical difficulty on the part of the chemical. It also shows that in some cases they do not allow the addition of the necessary admixtures, such as, for example, easily liquid tars, mineral oils and the like. Various attempts have been made to remove hot solids; basic varnishes were used for sealing and filling with hard substances, but all these attempts did not give good results, or I know the process of applying the mass for cold extrusion is too long, and the products lose their external appearance with the subsequent heating. get successful results by standing on. cold with the addition of various organic and inorganic ingredients, if the method of condensation of phenol and aldehyde under the condition of acid condensation is used, and in the first stage products are obtained that have the appearance of tar with a partial (incomplete) amount of raspberry form. These grout products are mixed with formalin and the admixtures that you wish to introduce in the presence of sulfur-petroleum acids, sulfurized fats or a sulfurized mixture of glycerides with aromatic hydrocarbons, as well as with their derivative. Example, 100 parts of phenolic tar obtained by 60 parts of 40% formalin and 5 parts of hydrochloric acid, 20 parts of sulfurized rapeseed oil, 30 parts of petroleum sulfa acids, 40 parts of 40% formalin, 100 parts of galvanic sun, 80 parts of porcelain clay, 20 parts of asbestos The tar is first mixed in this mixture when heated; phenolic, gas tar, sulfurized rapeseed oil, sulfonaphtic acids, then the mixture is cooled and formalin is introduced, porcelain clay and asbestos are then kneaded and the mass is left until it reaches the state in which it can be compacted . The items obtained are left for 10 to 12 hours at 30 ° to 40 ° C, and 3 to 4 hours at 80-90 ° C; At this point in the polymerization process, the mass obtained in this way can be used in electrical engineering for the production of rubber or vinyl records, in the chemical industry and for thermal insulation.
