Abstract

SEGUN LA INVENCION, EL LAPICERO PARA ESCRIBIR O PARA PINTAR SE OBTIENE POR TRIEXTRUSION DE TRES MATERIALES TERMOPLASTICOS QUE FORMAN EL MATERIAL DE LA MINA (1), EL MATERIAL DE MADERA EXPANDIDO (3) Y UNA CAPA INTERMEDIA (2) DE PROTECCION, EXENTA DE AGENTE DE EXPANSION, COMPATIBLE CON EL MATERIAL DE LA MINA () Y EL MATERIAL DE MADERA (3) Y QUE TIENE UNA TEMPERATURA DE FUSION QUE ES IGUAL O SUPERIOR A LA TEMPERATURA DE FUSION DEL MATERIAL DE LA MINA Y A LA DEL MATERIAL DE MADERA. LOS TRES MATERIALES COEXTRUIDOS CONTIENEN EN PARTICULAR LOS TRES EL MISMO COMPONENTE DE BASE, POR EJEMPLO UN COPOLIMERO POLIESTIRENO ETACRILATO. LA CAPA DE PROTECCION (2) PUEDE SER DE UN COLOR DIFERENTE DE LAS OTRAS DOS CAPAS. EL LAPICERO PARA ESCRIBIR O PARA PINTAR CON VAINA DE PROTECCION ENTRE LA MINA Y LA MADERA EXPANDIDA, LOS TRES DE MATERIAL TERMOPLASTICO, ES EN PARTICULAR UN LAPICERO CON MINA BLANDA O EXTRABLANDA.
