Abstract

Sposób modyfikacji polimerów krzemoorganicznych, zwłaszcza polidimetylosiloksanów, suszonym ziołem, charakteryzujący się tym, że napełniacz w postaci tymianku suszy się w temperaturze od 20°C do 25°C, korzystnie 22°C w czasie od 18 do 24 h, korzystnie 20 h, rozdrabnia na młynku czteronożowym w czasie od 2 do 4 minut, korzystnie 3 minuty albo aż do osiągniecia wielkości ziarna nie większej niż 500 µm, korzystnie 400 µm i przesiewa przez sita o wielkości oczka nie większej niż 100 µm, korzystnie 80 µm i tak przygotowany napełniacz miesza się z bazą silikonową w proporcji od 0,1:10 do 1:10 wagowo tymianek w stosunku do całego systemu polimerowego, w którym proporcje bazy silikonowej do katalizatora wynosi 1:1 wagowo w mieszadle obrotowym w czasie od 2,5 do 3 minut, korzystnie 3 minuty, jednocześnie stosując chłodzenie podczas mieszania, utrzymując temperaturę od 20°C do 40°C, korzystnie 23°C, następnie do mieszanki dodaje się katalizator platyny i tak otrzymany produkt odpowietrza się w suszarce próżniowej w czasie od 4 do 5 minut, korzystnie 5 minut, a następnie odlewa grawitacyjnie do form i poddaje się procesowi kondycjonowania, korzystnie w temperaturze od 30°C do 70°C, najkorzystniej 60°C w czasie od 30 do 120 minut, korzystnie 60 minut, a następnie kondycjonuje w temperaturze od 50°C do 90°C, korzystnie 80°C w czasie od 60 do 180 minut, korzystnie 120 minut. Przedmiotem zgłoszenia jest też opatrunek w postaci elastycznej folii charakteryzujący się tym, że ma grubość nie większą niż 4 mm i zawiera tymianek o zawartości 2,5%, 5%, 7,5% i 10% wagowo, a resztę stanowi polidimetylosiloksan.A method of modifying organosilicon polymers, especially polydimethylsiloxanes, with a dried herb, characterized in that the filler in the form of thyme is dried at a temperature of 20°C to 25°C, preferably 22°C for 18 to 24 h, preferably 20 h, crushed in a four-knife mill for 2 to 4 minutes, preferably 3 minutes or until the grain size is not greater than 500 µm, preferably 400 µm, and sieved through sieves with a mesh size of not greater than 100 µm, preferably 80 µm, and the filler prepared in this way is mixed with a silicone base in a proportion of 0.1:10 to 1:10 by weight of thyme in relation to the entire polymer system, in which the proportions of the silicone base to the catalyst are 1:1 by weight in a rotary mixer for 2.5 to 3 minutes, preferably 3 minutes, while applying cooling during mixing, maintaining the temperature from 20°C to 40°C, preferably 23°C, then the platinum catalyst is added to the mixture and the product thus obtained is deaerated in a vacuum dryer for 4 to 5 minutes, preferably 5 minutes, and then gravity cast into molds and subjected to a conditioning process, preferably at a temperature from 30°C to 70°C, most preferably 60°C for 30 to 120 minutes, preferably 60 minutes, and then conditioned at a temperature from 50°C to 90°C, preferably 80°C for 60 to 180 minutes, preferably 120 minutes. The subject of the application is also a dressing in the form of a flexible foil, characterised in that it has a thickness of not more than 4 mm and contains thyme in the amount of 2.5%, 5%, 7.5% and 10% by weight, the remainder being polydimethylsiloxane.
