Abstract

Tworzywo polimerowe o obniżonej palności jest mieszaniną, połączonych w sposób trwały polietylenu lub polipropylenu w ilości 40 - 90% wagowych, 10 - 60% wagowych odpadowych piór drobiowych o długości 0,3 - 5mm zawierających nie więcej niż 20% wagowych substancji tłuszczowych oraz kompatybilizatora mieszalności w ilości 2 - 5% wagowych. Sposób wytwarzania tworzywa polimerowego polega na tym, że na obracające się walce, których stosunek obrotów wynosi 1,2 - 1,5, nanosi się kolejne warstwy mieszaniny polietylenu lub polipropylenu z kompatybilizatorem mieszalności, zmieszanych w stosunku od 10 : 0,75 do 10 : 1, przy temperaturze walców 140 - 190°C. Następnie po uplastycznieniu mieszaniny na walcach i zwiększeniu szerokości szczeliny między walcami co najmniej do 2mm, wprowadza się do szczeliny przemyte gorącą wodą z detergentem lub nadtlenkiem wodoru odpadowe pióra drobiowe o długości 0,3 - 5mm, zawierające nie więcej niż 20% wagowych substancji tłuszczowych. Całość poddaje się dalszemu walcowaniu w czasie 10 - 15min, przy zwiększaniu szerokości szczeliny do 4 - 5mm, po czym odebrane ze szczeliny płaty tworzywa chłodzi się i po ewentualnym rozdrobnieniu przetwarza się metodą wtryskiwania, wytłaczania lub prasowania.Polymer material with reduced flammability is a mixture of permanently connected polyethylene or polypropylene in an amount of 40 - 90% by weight, 10 - 60% by weight of waste poultry feathers 0.3 - 5mm long containing not more than 20% by weight of fatty substances and a miscibility compatibilizer in an amount of 2 - 5% by weight. The method of producing polymeric material is based on the fact that on rotating rollers with a rotation ratio of 1.2 - 1.5, successive layers of a mixture of polyethylene or polypropylene with a miscibility compatibilizer are mixed, mixed in a ratio of 10: 0.75 to 10: 1, at a cylinder temperature of 140 - 190 ° C. Then, after plasticizing the mixture on the rollers and increasing the gap width between the rollers to at least 2mm, waste poultry feathers 0.3 - 5mm long, containing not more than 20% by weight of fatty substances, are washed into the gap with hot water with a detergent or hydrogen peroxide. The whole is subjected to further rolling during 10-15 minutes, increasing the gap width to 4-5 mm, after which the plastic sheets removed from the gap are cooled and after possible grinding processed by injection, extrusion or pressing.
