Embodiment 1

[0046] A graphene conductive PA12 material is applied to automobile oil pipelines, and the parts by mass of each component are as follows:

[0047]

[0048]

[0049] According to the above ratio, put each component in a mixer and mix them for 5-10 minutes, and ensure that the mixing is uniform, and then send the obtained mixture into a twin-screw extruder, and melt it (the barrel temperature of the extruder is 250°C), The screw speed is 400rpm, extruding, water cooling, air drying, and pelletizing to obtain the PA12 composite material. Afterwards, the composite material is directly put into the pipe equipment for pipe production, and the graphene nylon oil delivery pipe provided by the invention is obtained.

Abstract

The invention discloses a graphene antistatic low-gasoline-permeability oil delivery pipe and a preparation method thereof. Graphene prepared by adopting a high-quality oxidation-reduction method is thin in layer number and good in dispersity, the stability and the dispersity of the graphene are improved by adding a dispersing agent, the content of the graphene in the slurry is as high as 30% at most, no volatile organic compounds exist in the preparation process, the production environment is friendly, and large-scale production and use are facilitated. The graphene oil delivery pipe preparedby the method has good static electricity conduction characteristic and good barrier property, the permeation of ethanol gasoline in the pipe is greatly reduced, and the safety of the oil delivery pipe is further guaranteed.

Description

technical field [0001] The invention belongs to the field of polymer material compounding, and in particular relates to a graphene antistatic oil delivery pipe with low gasoline permeability and a preparation method thereof. Background technique [0002] CN105602155A discloses a graphene in-situ synergistic plasticizer and an artificial leather manufacturing method using a reduced plasticizer, which is characterized in that the graphene is first lipophilic modified, and then dispersed in the plasticizer in a certain proportion, A plasticizer for graphene in-situ synergism is obtained. The solid content of graphene is 0.5%-1%. Under the same conditions, it can reduce the amount of plasticizer used by more than 20% when applied to the manufacture of artificial leather, and realize the reduction of plasticizer use; the introduction of graphene can not only " "Riveting" plasticizer improves the migration resistance of the plasticizer, and also effectively improves the heat resi...
