Abstract

The invention discloses a preparation method and formula of an automobile fuel steam pipeline rubber material. The formula taking epichloro-hydrin rubber as a main raw material is adopted. According to the formula, the heat resistance of the material is improved by adopting a vulcanization system of 2,4,6-trithioltriazine, an anti-ageing system of nickel dibutyl dithiocarbamate and a plastification system of alkyl ether adipate; the low temperature resistance of the material is improved by adopting a plastification system of dioctyl sebacate; the rubber material with resistance to high temperature of 150 DEG C and low temperature of -40 DEG C is prepared by adopting the corresponding technical scheme of the preparation method, and an automobile fuel steam pipeline rubber product prepared from the material achieves the purposes that the high temperature resistance and the low temperature resistance are improved, the increasing requirements for the rubber product caused by the automobile industry are met, and the WSD-M96D9-A standards are met.

Description

technical field [0001] The invention relates to a preparation method of a rubber material, in particular to a preparation method of a rubber material for an automobile fuel vapor pipeline used for manufacturing rubber products of the automobile fuel vapor pipeline. Background technique [0002] Rubber products for automobile fuel vapor pipelines are required to be resistant to fuel vapor, high temperature of 150°C, and low temperature of -40°C, and meet the requirements of the WSD-M96D9-A standard and the requirements of the ELV directive. The existing technology uses epichlorohydrin rubber materials to make automobile fuel oil Steam pipeline rubber products, products made of existing technical materials are difficult to meet the requirements of the WSD-M96D9-A standard, as follows: [0003] Test data of automobile fuel vapor pipeline rubber products made of prior art epichlorohydrin rubber materials [0004] Standard specification WSD-M96D9-A [0005] [0006] Other pr...
