Abstract

The invention belongs to the technical field of composite resin materials, and particularly relates to a composite resin material for a pressure gas storage container and a preparation method thereof. The preparation method of the composite resin material for a pressure gas storage container, provided by the invention, comprises the following steps of: mixing carbon nanotubes and dispersed oil to prepare carbon nanotube slurry; mixing nylon 6 and high-density polyethylene to form a resin mixture; and melting the resin mixture in a twin-screw extruder, adding the carbon nanotube slurry, and carrying out extrusion granulation to obtain the composite resin material. According to the preparation method provided by the invention, the dispersity of the carbon nanotubes in the matrix resin can be improved, so that the low-temperature performance of the composite material is improved, and the heat dissipation performance is improved.

Description

Technical field

[0001] The present application belongs to the technical field of composite resin material, and more particularly to a composite resin material for pressure gas storage containers and a preparation method thereof. Background technique

[0002] The hydrogen storage system is one of the core components of the fuel cell system, which includes high-pressure hydrogen storage bottles, safety valves, and pipelines. Among them, high-pressure storage bottles are mainly responsible for storing high pressure gant hydrogen, its working conditions, and health status determine the safety of the entire fuel cell car and service life. Plastic liner, carbon fiber all-wound four high-pressure storage bottles, due to light weight, high gas storage density, and more likely to be more likely to be more likely to be more likely to exceed metal systems, and are widely expected by the market. Currently, the four high-pressure hydrogen storage bottles are mainly applied to a more sensitive...
