Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania polimerowych nanokompozytów włóknistych, poprzez modyfikację właściwości tworzywa termoplastycznego lub kompozycji zawierającej tworzywo termoplastyczne. Sposób ten polega na tym, że do tworzywa termoplastycznego wybranego z grupy obejmującej polialefiny, poliacetale, polimery winylowe, poliamidy, poliestry, polistyren lub polimery biodegradowalne, ewentualnie ze znanymi dodatkami, dodaje się polimer krystalizujący o temperaturze krystalizacji wyższej niż temperatura topnienia lub zeszklenia tworzywa termoplastycznego wybrany z grupy obejmującej polimer krystalizujący o temperaturze krystalizacji wyższej niż temperatura topnienia lub zeszklenia tworzywa termoplastycznego, i którego temperatura krystalizacji jest wyższa co najmniej o 10°C od temperatury podczas ścinania, 150°C - 190°C, w ilości od 0.1% wagowych do 15% wagowych, po czym uzyskaną w ten sposób kompozycję poddaje się działaniu sił ścinających w zakresie szybkości ścinania od 10 s-1 do 2000 s-1 w temperaturze wyższej niż temperatura topnienia lub zeszklenia tworzywa termoplastycznego, korzystnie polegającym na mieszaniu składników przy dużych szybkościach ścinania, aż do uzyskania przekształcenia polimeru dodawanego w pojedyncze włókna o rozmiarze poprzecznym w zakresie od 10 do 2000 nanometrów, krystalizujące wskutek krystalizacji indukowanej ścinaniem, po czym ewentualnie przetwarza się uzyskany nanokompozyt metodą wytłaczania, wtrysku lub termoformowania w przedziale temperatur pomiędzy temperaturą topnienia lub zeszklenia tworzywa termoplastycznego i temperaturą topnienia polimeru dodawanego.The subject of the application is a method of producing polymeric fibrous nanocomposites by modifying the properties of a thermoplastic or a composition containing a thermoplastic. The method consists in adding to a thermoplastic selected from the group consisting of polyalefins, polyacetals, vinyl polymers, polyamides, polyesters, polystyrene or biodegradable polymers, possibly with known additives, a crystallizing polymer with a crystallization temperature higher than the melting or glass transition temperature of the thermoplastic is added. selected from the group consisting of a crystallizing polymer with a crystallization temperature higher than the melting or glass transition temperature of the thermoplastic, and whose crystallization temperature is at least 10 ° C higher than the shear temperature, 150 ° C - 190 ° C, in an amount from 0.1% by weight to 15% by weight, after which the composition obtained in this way is subjected to shear forces in the shear rate range from 10 s-1 to 2000 s-1 at a temperature higher than the melting or glass transition temperature of the thermoplastic, preferably consisting of mixing the components at high shear rates until obtaining can transform the added polymer into individual fibers with a transverse size in the range from 10 to 2000 nanometers, crystallizing due to shear-induced crystallization, and then possibly the resulting nanocomposite is processed by extrusion, injection or thermoforming in the temperature range between the melting or glass transition temperature of the thermoplastic and the melting point polymer added.
