AGEING-RESISTANT RUBBER COMPOSITION AND PROCESSING METHOD THEREFOR AND USE THEREOF

Disclosed are an aging-resistant rubber composition and a processing method therefor and use thereof. The rubber composition includes a rubber matrix and compounding components, and in parts by weight, every 100 parts of said rubber matrix comprise 50-99 parts of a halogenated butyl rubber, 0-50 parts of a highly branched polyethylene P1, and 0-50 parts of P2 obtained by the polarization modification of said highly branched polyethylene P1, and the sum of P1 and P2 in parts by weight is 1-50 parts; and said compounding components comprise a vulcanization system. The rubber composition improves the heat aging resistance of the halogenated butyl rubber, making it more suitable for high temperature environments, and also improves the properties of the halogenated butyl rubber which are related to the halogen content, such as the adhesiveness, oil resistance, flame retardancy and the like, by adjusting the extent of halogenation of the highly branched polyethylene which is employed in combination, thereby overcoming the limitation caused by the halogen content of the halogenated butyl rubber.
