Title: Innovations of Leopold Golser in Foamed Plastics
Introduction
Leopold Golser is a notable inventor based in Leonding, Austria, recognized for his contributions to the field of foamed plastics. With a total of three patents to his name, Golser has developed innovative processes that enhance the production and characteristics of foamed plastics.
Latest Patents
Golser's latest patents include a process and apparatus for the continuous production of foamed plastics. This continuous process focuses on producing flame-resistant foamed plastics material through the condensation of aqueous aminoplast precondensates with diisocyanates or polyisocyanates. In the first mixing stage, the isocyanate is combined with 4 to 14% by weight of a catalyst, which can be an organic amine or an organic metal compound, at temperatures ranging from 40 to 130 degrees Celsius. The residence time for this stage is between 1 to 8 seconds. Following this, the aminoplast precondensate and an acid curing catalyst are introduced in a second mixing stage, resulting in a foamable mixture that is discharged continuously. The apparatus designed for this process features two mixing chambers connected in series, with specific design ratios to optimize the mixing process.
Another significant patent by Golser is a process for the manufacture of foamed plastics with improved combustion characteristics. This process involves condensing aqueous solutions of aminoplast precondensates with bifunctional organic isocyanates, utilizing an acid curing catalyst and an accelerator for polyurethane formation. The aqueous solution of the precondensate is added to the mixture of isocyanate and accelerator simultaneously but separately from the acid curing catalyst.
