Description
Wynalazek dotyczy srodka do zmniejszania przyczepnosci drewna i zelaza do betonu.Srodki tego rodzaju posiadaja duze znaczenie w przemysle budowlanym, gdyz z jednej stro¬ ny pozwalaja na zwiekszenie trwalosci drewna szalunkowego i zapobiegaja uszkodzeniu betonu podczas zdejmowania wspomnianych szalowan, z drugiej zas strony, wskutek powodowanego przez nie zmniejszenia przyczepnosci betonu do zelaznych form, stosowanych przy produkcji prefabrykatów, ulatwiaja wyjmowanie tych be¬ tonowych pólfabrykatów z form umozliwiajac jednoczesnie otrzymanie gladkiej ich powierz¬ chni.^ , Znane dotychczas srodki do zmniejszenia przy¬ czepnosci drewna i zelaza do betonu sa oparte na surowcach, których brak daje sie odczuwac na rynku, albo tez na surowcach, stanowiacych poszukiwany material dla przemyslu tluszczowe¬ go lub wlókienniczego, do których to surowców ztOiczyó nalezy, stoaowane w istniejacych srod¬ kach do zmniejszania wspomnianej przyczepno¬ sci, kwasy naftenowe i mydla naftenowe.Niedogodnosci te usuwa srodek wedlug wy¬ nalazku, który rózni sie od znanych tym, ze sklada sie z roztworu soli sodowych i potaso¬ wych, sulfokwasów oraz z dowolnego rozpusz¬ czalnika, najkorzystniej o temperaturze wrzenia powyzej 100°C. Jako rozpuszczalnik stosuje sie korzystnie weglowodory szeregu parafinowego i aromatycznego o temperaturze wrzenia powy¬ zej 100°C, natomiast jako roztwór soli sulfokwa¬ sów stosuje sie zgodnie z wynalazkiem lugi po¬ rafinacyjne, otrzymane przez zobojetnianie za pomoca lugu sodowego lub potasowego sulfo¬ kwasów, powstalych przy rafinacji olei mineral¬ nych stezonym kwasem siarkowym.Nalezy zaznaczyc, ze tego rodzaju lugi pora¬ finacyjne znajduja sie w duzej ilosci w rafi¬ neriach i sa uciazliwym materialem odpadowym.Stwierdzono, ze srodek wedlug wynalazku da¬ je dobre wyniki przy zastosowaniu w nim 60—* 70 czesci wagowych wysuszonych lub wysolo- nych lugów porafinacyjnych oraz 30 — 40 cze¬ sci wagowych rozpuszczalnika, np. w postaci mieszaniny frakcji ksylenowych i solwent nafty. i . PLThe invention relates to an agent for reducing the adhesion of wood and iron to concrete. Measures of this type are of great importance in the construction industry, because on the one hand they make it possible to increase the durability of the formwork wood and prevent damage to the concrete during the removal of the above-mentioned formwork, on the other hand due to by reducing the adhesion of concrete to iron-based molds used in the production of prefabricated elements, they facilitate the removal of these concrete blanks from the molds, while allowing a smooth surface to be obtained. The hitherto known means for reducing the adhesion of wood and iron to concrete are based on raw materials, the lack of which can be felt on the market, or on raw materials, which are a sought-after material for the fat or textile industry, which include the raw materials of the abovementioned substances, used in the existing means to reduce the said adhesion, naphthenic acids and soaps naphthenic. Inconvenience and removes an inventive agent which differs from those known in the art in that it consists of a solution of sodium and potassium salts, sulfo acids, and any solvent, most preferably boiling above 100 ° C. Hydrocarbons of the paraffinic and aromatic series with a boiling point of more than 100 ° C. are preferably used as the solvent, and refining liquors obtained by neutralization with sodium or potassium sulphate liquor are used as the solution of sulfo acid salts according to the invention. refining mineral oils with concentrated sulfuric acid. It should be noted that this type of refining slurry is found in large amounts in refineries and is a troublesome waste material. It has been found that the agent according to the invention gives good results when used in 60-70 parts by weight of the dried or salted post-refining slurry and 30-40 parts by weight of a solvent, for example in the form of a mixture of xylene fractions and a kerosene solvent. and.
