Problems solved by technology

[0003] The prior art adopts the method of grafting adhesive to bond nitrile / polyvinyl chloride blended rubber with fluororubber to make an oil-resistant rubber hose compounded with fluororubber; the composite oil-resistant rubber hose made by grafting bonding method is actually In application, the composite layer is prone to delamination and detachment due to weak adhesion and quality problems. At the same time, the cost of the grafted adhesive is relatively high, resulting in an increase in the cost of the composite oil-resistant hose. Therefore, the existing technology exists The problems and deficiencies of weak adhesion and high cost

Abstract

The invention discloses a preparation technology of a butyronitrile / polrvinyl chloride (PVC) blending rubber capable of being bonded with fluororubber, and comprises a formula and a process flow of preparation. The invention adopts a formula in which butyronitrile / polrvinyl blending rubber can have good bonding capability with fluororubber, and a corresponding preparation method is coordinated toovercome the problems of weak adhesive force and high cost of the prior art. The provided preparation technology thereof prepares the butyronitrile / PVC blending rubber capable of being bonded with the fluororubber without using stem grafting adhesive so as to replace the stem grafting adhesion method by a direct combining method to manufacture an oil resisting rubber hose compounded with the fluororubber, and enable the oiling connecting rubber pipe of an automobile oil tank to achieve the aims of enhancing the bonding capability, avoiding the layering separation and lowering the cost in the premise of meeting the various mechanical strength and typical properties and conforming to the instruction requirement of ELV.

Description

technical field [0001] The invention relates to an oil-resistant synthetic rubber and a preparation method thereof, in particular to a nitrile / polyvinyl chloride blended rubber material which is used for manufacturing an oil-filling connecting rubber pipe of an automobile fuel tank and can be well bonded to fluororubber. Technology for the preparation of bonded nitrile / polyvinyl chloride rubber blends. Background technique [0002] Nitrile / polyvinyl chloride blended rubber, also known as oil-resistant rubber, is widely used in the manufacture of oil-resistant rubber products such as automobile oil pipes and oil rubber hoses. In order to further improve the service life of the oil pipe products, the automobile fuel tank oil filling connecting hose adopts an inner and outer two-layer composite structure. Polyvinyl chloride blended rubber is used to make an oil-resistant rubber hose with a composite structure on the outer layer; fluororubber is a kind of synthetic rubber with ...
