Abstract
The invention relates to a low-permeability refueling hose composition and a preparation method thereof. The low-permeability refueling hose composition is prepared from the following components: nitrile rubber/polyvinyl chloride, zinc oxide, stearic acid, an anti-ageing agent RD, an anti-ageing agent NAUGARD445, fast extruding carbon black N550, a filler Sillitn N-85, a plasticizer TP759, trioctyl trimellitate, an accelerant disulfide drewamine (DTDM), an accelerant CZ and an accelerant DM. The method comprises a process of carrying out mixing processing according to the raw materials and the dosage in the formula, namely weighing rubber and the raw materials, internally mixing a segment, milling a segment, batching off, internally mixing two segments, milling two segments, and batching off. The product disclosed by the invention adopts a blending material of the nitrile rubber and the polyvinyl chloride; the requirements of the permeability, the good ozone ageing resistance and the like can be met by using a single-layer all-rubber structure.
Description
Technical field
The present invention relates to sebific duct technical field, particularly automobile fuel filler hose compositions and preparation method.
Background technology
Be accompanied by the develop rapidly of automotive industry, to vehicle fuel penetrating quality, require more and more high.The oil port flexible pipe of at present general double-layer structure, from the inside to the outside successively: paracril/chlorosulfonated polyethylene rubber, its fuel oil perviousness can not meet and be less than 100g/m
2the standard-required in/sky.And another employing viton is inner glue layer, epichlorohydrin rubber is the oil port flexible pipe of outer glue-line, and its fuel oil perviousness is very little, but the material price of viton and epichlorohydrin rubber is very expensive, cause the oil port flexible pipe price that uses its production, a lot of motor corporations can not generally be used.And owing to adopting inside and outside two-layer rubber, it must use professional double plex extruder to produce, and common individual layer forcing machine can not be produced this infrastructure product.
Summary of the invention
Object of the present invention is mainly to provide a kind of hyposmosis refueling hose, high to solve current paracril/chlorosulfonated polyethylene rubber refueling hose rate of permeation, and the high problem of viton/epichlorohydrin rubber oil port flexible pipe cost.
The product of our invention, adopts paracril and polychloroethylene blended material, uses the full plastic structure of individual layer can meet fuel oil infiltration and resistance to ozone ageing requirement etc.
