Abstract:V članku je podan pregled razvoja proteinskih lepil na osnovi soje, krvi in kazeina. Članek obravnava formulacije in tehnologije lepljenja teh proteinskih lepil iz obdobja 1930-1960 ter današnje komercialne formulacije. V tem obdobju so bile namreč poraba ter tehnološke izboljšave proteinskih lepil na vrhuncu. Pri obravnavi današnjih formulacij in tehnologij lepljenja je poudarek na sojinih lepilih, saj se le-ta uporabljajo v industriji lepljenja dekorativnih vezanih, ivernih in vlaknenih plošč ter parketa. Kazein se danes uporablja le še v lepilih za protipožarna vrata, medtem ko se živalska kri v lepilih ne uporablja več. Proteinska lepila iz obdobja 1930%1960 sicer ne ustrezajo zahtevam današnjih standardov in se zato več ne uporabljajo, so pa vse opisane tehnologije še vedno uporabne in se lahko ponovno uvedejo, če bodo svetovni viri nafte usahnili.

Title:Past and present protein adhesives based on soy, blood and casein
Abstract:This paper reviews the development of protein adhesives, specifically soy, blood, and casein adhesives. It addresses the formulations and bonding technologies of these protein adhesives from 1930 to 1960, and current commercial formulations. Between the 1930s and 1960s the consumption and technological refinements of protein adhesives were at their peak. Addressing current formulations and bonding technologies, the emphasis is on the soy adhesives, since they are used in industry of decorative plywood, particleboard, fibreboard, and engineered wood flooring. Today, casein is used only in adhesives for fire-resistant wood doors, while animal blood is no longer utilised in adhesives. Although the formulations from 1930 to 1960 do not meet current standards and are no longer used today, all described technologies are still usable and may be reintroduced if the world's crude oil resources are dried up.
Keywords:protein adhesives, wood, soy, blood, casein, formulations, bonding technology
