The invention discloses an HDPE harvester fuel tank and a preparation method thereof. The HDPE harvester fuel tank sequentially comprises an HDPE outer layer, a bonding layer, a blocking layer, an adhesive layer and an HDPE inner layer from outside to inside; the blocking layer comprises at least one of nylon PA and an ethylene-vinyl alcohol copolymer EVOH; the bonding layer and the adhesive layereach independently comprise maleic anhydride grafted high-pressure polyethylene or maleic anhydride grafted low-pressure polyethylene; the forming process of the HDPE inner layer is carried out in anitrogen environment containing fluorine gas. The HDPE harvester fuel tank has excellent fuel leakage resistance; and the preparation method has the advantages of few raw materials and simple processing technology.

    本发明公开了一种HDPE收割机燃油箱及其制备方法,该HDPE收割机燃油箱由外向内依次包括HDPE外层、粘结层、阻隔层、黏结层和HDPE内层,阻隔层包括尼龙PA和乙烯‑乙烯醇共聚物EVOH中的至少一种;粘结层和黏结层各自独立地包括马来酸酐接枝高压聚乙烯或马来酸酐接枝低压聚乙烯;其中,HDPE内层的成型过程在含氟气的氮气环境中进行。该HDPE收割机燃油箱具有优异的抗燃油渗漏能力,同时该制备方法具有原料少和加工工艺简单的优点。
