Abstract
The invention relates to nitrile-butadiene rubber bonded with fluororesin or fluororubber and an application thereof in a fuel pipe. The rubber comprises the following components: raw nitrile-butadiene rubber, magnesium oxide, calcium hydroxide, stearic acid, an antiager RD, an antiager NBC, coumarone, an adhesive Ricobond 2031, fast extruding furnace black N550, high abrasion furnace black N330, white carbon black, trioctyl trimellitate, liquid nitrile-butadiene rubber 26, sulfur, an accelerator CZ and an accelerator TMTD (tetramethylthiuram disulfide). The experimental contrastive analysis on nitrile-butadiene rubber, epichlorohydrin rubber and ethyene-propylene rubber shows that the performances of the nitrile-butadiene rubber can fully meet the standard and the nitrile-butadiene rubber can replace epichlorohydrin rubber and ethyene-propylene rubber. A vehicle rubber pipe prepared from the nitrile-butadiene rubber can meet the normal production conditions and performance requirement, and simultaneously, the material cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of rubber, in particular to a nitrile rubber used for automobile rubber hoses. Background technique [0002] With the rapid development of the automobile industry, the automobile rubber hose is also constantly developed and updated. The low-permeability fuel hose uses fluororesin and fluororubber as the shielding layer, and chloroether rubber and ethylene acrylate rubber are mostly used for bonding. However, continuing to use epichloride rubber or ethylene acrylate rubber materials at temperatures below 100°C is too costly and has excess performance. Therefore, in the environment with low temperature, we use relatively cheap rubber to replace epichlorohydrin rubber or ethylene acrylate rubber, which can not only meet the requirements of product use, but also reduce the cost of materials; therefore, the development of such rubber has become the current main topic. .
