Abstract

PROCEDIMIENTO DE FABRICACION DE UN MATERIAL EN FORMA DE PELICULA PARA LA PROTECCION DE SUPERFICIES ADHESIVAS.COMPRENDE: A) MEZCLAR INTIMAMENTE 50 A 85 % EN PESO DE UN POLIMERO EN POLVO ESCOGIDO ENTRE POLIETILENO DE BAJA DENSIDAD, POLIETILENO DE ALTA DENSIDAD, POLIPROPILENO, POLIAMIDAS, POLI(ACETATO DE VINILO), POLI(ALCOHOL VINILICO), UN AGENTE TENSIOACTIVO NO IONICO, COMO ALCOHOLES GRASOS POLIOXIETILENADOS, POLIGLICEROLADOS, ESTERES DE SORBITOS Y OTROS, Y UN JABON METALICO FORMADO POR UN ALQUIL-CARBOXILATO DE ALUMINIO, CALCIO, MAGNESIO, O CINC; B) CALENTAR LA MEZCLA A UNA TEMPERATURA COMPRENDIDA ENTRE 150 Y 250 C PARA OBTENER UNA PASTA HOMOGENEA; C) REALIZAR LA EXTRUSION DE DICHA PASTA A UNA PRESION DE 1.000 A 1.500 BARES DE MODO QUE SE FORME UNA PELICULA; Y D) ENFRIAR DICHA PELICULA HASTA 15 O 20 C, PARA ASEGURAR SU SOLIDIFICACION MEDIANTE UNA CORRIENTE DE AGUA.SE UTILIZA COMO SUSTITUTIVO DE LOS PAPELES REVESTIDOS POR RESINAS DE SILICONA.
