Abstract
PROCESSO DE OBTENÇçO DE VERNIZ EM Pà TERMOPLÁSTICO A PARTIR DE POLI(TEREFTALATO DE ETILENO) PàS-CONSUMO, VERNIZ EM Pà OBTIDO E ARTIGOS RESULTANTES. É descrito um processo de obtenção de verniz em pó termoplástico a partir de poli(tereftalato de etileno) (PET) pós-consumo, que compreende prover PET pós-consumo com V.l. entre 0,46 a 0,84 g/dL, que é extrusado com 0,01 a 1,0% de umidade, de modo a degradar o polímero PET até VI na faixa de 0,33 - 0,52 g/dL. O produto extrusado é moído, em temperatura ambiente, até distribuição de tamanho de partícula na faixa de 75 a 425 pm e aplicado sobre suporte metálico, e submetido a temperaturas entre 250°C e 300°C até obtenção de filme, o filme obtido sendo resfriado bruscamente a temperaturas entre 15 e 35°C. O filme amorfo de verniz termoplástico translúcido de PET é recuperado, aderido ao suporte metálico, formando um artigo com propriedades compatíveis com os usos pretendidos.PROCESS FOR OBTAINING THERMOPLASTIC POWDER VARNISH FROM POLY (ETHYLENE TEREPHALATE) BY CONSUMPTION, POWDER VARNISH AND RESULTING ARTICLES. A process for obtaining thermoplastic powder varnish from post-consumer polyethylene terephthalate (PET) is described which comprises providing post-consumer PET with V.l. 0.46 to 0.84 g / dL, which is extruded at 0.01 to 1.0% moisture, to degrade PET polymer to VI in the range of 0.33 - 0.52 g / dL. The extruded product is milled at room temperature to particle size distribution in the range of 75 to 425 pm and applied on metal support, and subjected to temperatures between 250 ° C and 300 ° C until film is obtained. abruptly cooled to temperatures between 15 and 35 ° C. The amorphous translucent thermoplastic varnish PET film is recovered, adhered to the metal support, forming an article with properties compatible with the intended uses.
