Abstract

Procedimiento para conformar PET celular a partir de preformas sólidas.#El procedimiento comprende las etapas de: (a) acondicionar una preforma sólida (1) hecha de PET (polietilentereftalato) previamente obtenida por extrusión, moldeo o termoconformado, ajustando su concentración de humedad a su valor de concentración en el equilibrio; (b) disolver en dicha preforma sólida (1) un gas inerte a presión y temperatura durante un tiempo suficiente hasta saturación, y descompresión a temperatura ambiente, con lo que se obtiene la preforma sólida (1) saturada de gas; y (c) colocar en un molde de conformado no metálico la preforma sólida (1) saturada de gas y aplicar una radiación de microondas sobre el conjunto para producir el reblandecimiento, expansión y conformado simultáneo de la preforma sólida (1) hasta obtener un producto celular (6).Procedure for forming cellular PET from solid preforms. # The procedure comprises the steps of: (a) conditioning a solid preform (1) made of PET (polyethylene terephthalate) previously obtained by extrusion, molding or thermoforming, adjusting its moisture concentration to its concentration value in equilibrium; (b) dissolving in said solid preform (1) an inert gas at pressure and temperature for a sufficient time until saturation, and decompression at room temperature, whereby the solid preform (1) saturated with gas is obtained; and (c) place the solid preform (1) saturated with gas in a non-metallic forming mold and apply microwave radiation on the assembly to produce the softening, expansion and simultaneous shaping of the solid preform (1) until a product is obtained cellular (6).

The object of the invention is a method for forming cellular PET from solid preforms. El documento D01 divulga un proceso de obtención de un material celular a partir de una preforma sólida de un polímero termoplástico (poliéster, PET, policarbonato, …) obtenido por extrusión en el que se disuelve un gas inerte como dióxido de carbono a presión superior a 80 bar y temperatura entre 40 y 200ºC, se produce una descompresión y a continuación un calentamiento mediante varios posibles métodos, entre ellos la radiación de microondas . (ver párrafos 26-56) Document D01 discloses a process for obtaining a cellular material from a solid preform of a thermoplastic polymer (polyester, PET, polycarbonate, ...) obtained by extrusion in which an inert gas such as carbon dioxide is dissolved at a pressure greater than 80 bar and temperature between 40 and 200 ° C, decompression occurs and then heating by several possible methods, including microwave radiation. (see paragraphs 26-56) En consecuencia, las reivindicaciones 1-3, 5-6 y 8-9 de la solicitud carecen de novedad a la luz de lo divulgado en el documento D01. (Art. 6.1 LP) Consequently, claims 1-3, 5-6 and 8-9 of the application are not new in the light of what is disclosed in document D01. (Art. 6.1 LP) En cuanto a las reivindicaciones dependientes 4, 7 y 10, no contienen ninguna característica que, en combinación con las características de la reivindicación de la que dependen, cumplan la exigencia establecida respecto a actividad inventiva ya que reflejan condiciones de operación que, en ausencia de un efecto técnico inesperado, corresponden a ejecuciones rutinarias que el experto en la materia ensayaría de cara a la optimización del proceso. As for the dependent claims 4, 7 and 10, they do not contain any characteristics that, in combination with the characteristics of the claim on which they depend, meet the established requirement regarding inventive activity since they reflect operating conditions that, in the absence of An unexpected technical effect corresponds to routine executions that the person skilled in the art would test in order to optimize the process. En consecuencia, las reivindicaciones 4, 7 y 10 de la solicitud carecen de actividad inventiva a la luz de lo divulgado en el estado de la técnica. (Art. 8.1 LP) Accordingly, claims 4, 7 and 10 of the application lack inventive activity in the light of what is disclosed in the prior art.
