Abstract

Przedmiotem wynalazku jest kompozyt polilaktydu z opoką wapnistą jako napełniaczem na osnowie polilaktydu PLA, z dodatkiem wosku pszczelego lub wosku syntetycznego jako kompatybilizatorów, sposób jego wytwarzania oraz zastosowanie do produkcji wyrobów z tworzyw sztucznych. Kompozyt polilaktydu z opoką wapnistą jako napełniaczem na osnowie polilaktydu PLA składa się z 70%-96,25% wagowych polilaktydu PLA i 30%-3,75% wagowych opoki i/lub zawierających 1% wagowych w przeliczeniu na masę PLA/opoka wosku pszczelego lub wosku syntetycznego jako kompatybilizatorów. Sposób wytwarzania kompozytu w postaci koncentratu polega na tym, że 70% wagowych polilaktydu PLA podgrzewa się powyżej temperatury mięknienia do uzyskania polimeru w stanie uplastycznionym, dalej dodaje się 30% wagowych opoki wapnistej i/lub 1% wagowy wosku pszczelego w przeliczeniu na masę kompozytu PLA/opoka i/lub 1% wagowy wosku syntetycznego w przeliczeniu na masę kompozytu PLA/opoka, następnie polimer wraz z napełniaczem miesza się do uzyskania jednorodnej masy, dalej studzi się, granuluje i suszy w podwyższonej temperaturze. Zastosowanie kompozytu polilaktydu z opoką wapnistą do druku 3D w postaci żyłki - filamentu, uzyskanego przez dodanie do koncentratów czystego polimeru polilaktydu PLA w odpowiednich stosunkach wagowych do rozcieńczenia układów do stężeń 3,75% wagowych opoki, 7,5% wagowych opoki, 15% wagowych opoki lub poprzez wytłoczenie koncentratu zawierającego 30% wagowych opoki.The subject of the invention is a polylactide composite with limestone as a filler on a polylactide PLA base, with the addition of beeswax or synthetic wax as compatibilizers, a method of its production and use for the production of plastic products. The polylactide composite with limestone as a filler on a polylactide PLA base consists of 70%-96.25% by weight of polylactide PLA and 30%-3.75% by weight of limestone and/or containing 1% by weight in terms of the weight of PLA/rock of beeswax or synthetic wax as compatibilizers. The method of producing a composite in the form of a concentrate consists in heating 70% by weight of polylactide PLA above the softening temperature until the polymer is in a plasticized state, then adding 30% by weight of limestone and/or 1% by weight of beeswax based on the weight of the PLA/rock composite and/or 1% by weight of synthetic wax based on the weight of the PLA/rock composite, then mixing the polymer with the filler until obtaining a homogeneous mass, further cooling, granulation and drying at an elevated temperature. Application of a polylactide composite with limestone for 3D printing in the form of a filament, obtained by adding pure polylactide PLA polymer to concentrates in appropriate weight ratios to dilute the systems to concentrations of 3.75% limestone, 7.5% limestone, 15% limestone or by extruding a concentrate containing 30% limestone by weight.
