Abstract

The invention discloses a preparation method of a rubber material for preparing heat and compressive deformation resistant rubber products for vehicle pipelines. The method includes the following steps of: (1) introducing water to cool a Banbury mixer; banburing a rubber material, reinforcing fillers, a plasticizer, activators, and anti-aging agents in the Banbury mixer; unloading rubber under a rubber temperature of below 120 DEG C; forming sheets on an open mill; and cooling to obtain master batch; and (2) inputting the master batch into the Banbury mixer; blending under uniform addition of vulcanizing agents; unloading rubber under rubber temperature of below 90 DEG C; forming strips on the open mill; and cooling and standing for aging to obtain the heat and compressive deformation resistant rubber material used for manufacturing products such as vehicle vacuum booster pipelines. The rubber products of vehicle vacuum booster pipelines manufactured by using the produced rubber material pass detections for various mechanical strength and physical and chemical indicators, meet ELV (End-of Life Vehicles) directive requirements, have improved heat and compressive deformation resistant performance, satisfy increasingly high requirements of vehicle industry on rubber products, and accord with Nissan NES D8601 standards.
