Abstract

Neumático de forma toroidal (1) compuesto por dos talones (2) distanciados el uno del otro, relativamente inextensibles; por una banda de rodamiento circunferencial (6) diseñada para entrar en contacto con la carretera; por paredes laterales (3) que se extienden desde dichos talones hasta dicha banda de rodamiento y por una carcasa que incluye dicha banda de rodamiento y dichas paredes laterales, dicha carcasa compuesta por al menos una capa de caucho (5) reforzada con unos hilos que se extienden desde un talón hasta el otro; en el que se coloca una pieza añadida (8) de una composición de caucho entre la banda de rodamiento externa radial (6) y el talón interno radial (2) caracterizado por el hecho de que dicha pieza añadida es de una composición de caucho compuesta, basándose en 100 phr de elastómero(s), por: (A) al menos un elastómero seleccionado a partir de homopolímeros y copolímeros de hidrocarburos de dieno conjugado que tienen de 4 a 6 átomos de carbono, y de copolímeros de hidrocarburos conjugados que tienen de 4 a 6 átomos de carbono, y de estireno, (B) de 5 a 50 phr de un polietileno granulado de peso molecular ultra elevado, cuyo peso molecular se sitúa en una gama desde 4.5 millones hasta 8 millones con un punto de fusión según el método ISO No. 306 en una gama desde 130°C hasta 150°C, dispersado en dicha composición de caucho de dicha pieza añadida, (C) de 5 a 40 phr de un compuesto granulado de almidón/plastificante dispersado en dicha composición de caucho de dicha pieza añadida, y (D) de 10 a 50 phr de al menos una carga de refuerzo seleccionada entre negro de carbón, sílice precipitado, aluminosilicato, y negro de carbón modificado con unidades de silanol en su superficie, (E) un agente de adherencia para dicho sílice, aluminosilicato, negro de carbón modificado y compuesto de almidón, cualquiera que sea el caso, que tiene un grupo reactivo con las unidades de silanol contenidas en la superficie del sílice, del aluminosilicato o de dicho negro de carbón modificado y con las unidades de hidróxilo contenidas en dicho compuesto de almidón, y otro grupo interactivo con dicho(s) elastómero(s); donde dicho almidón está compuesto por unidades de amilosa y unidades de amilopectina en una proporción de 15/85 a 35/65, de forma alternativa de 20/80 a 30/70, y con un punto de reblandecimiento según la ASTM No. D1228 en una gama de 180°C a 220°C; donde dicho compuesto de almidón/plastificante tiene un punto de reblandecimiento en una gama de 110°C a 170°C, y donde el plastificante es un plastificante polimérico con un punto de reblandecimiento inferior a 160°C; donde dichos puntos de reblandecimiento están determinados según la ASTM No. D1228.
