The invention discloses a low-permeability plastic fuel tank shell material and a preparation method thereof, comprising mixing and curing agent of one or both of thermoplastic polyester and thermoplastic resin; the thermoplastic polyester includes polyethylene, polypropylene, polyethylene One or more of terephthalate is mixed, and the thermoplastic resin includes one or more of polyamide, polyimide, polycarbonate, polyester and polysulfone. In the present invention, the thermoplastic polyesters of polyethylene, polypropylene and polyethylene terephthalate have better properties than thermoplastic resins of polyamide, polyimide, polycarbonate, polyester and polysulfone. Zinc oxide accelerates the cooling rate of thermoplastic polyester and thermoplastic resin during cooling molding, thermoplastic resin has better barrier property to fuel, that is, has lower permeability, mixing thermoplastic resin with thermoplastic polyester makes Plastic fuel tanks made from both have low permeability, reducing safety concerns. |
