Abstract

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.

Description

technical field [0001] The invention relates to a fuel tank, in particular to an HDPE harvester fuel tank and a preparation method thereof. Background technique [0002] Plasticization of fuel tanks is an important direction of plasticization of modern vehicles. Due to its excellent performance, HDPE materials are more and more widely used in automobiles. Among them, the more representative plastic product is HDPE fuel tank. Compared with metal fuel tanks, HDPE fuel tanks have the following advantages: large degree of freedom in shape design, light weight, good corrosion resistance, especially in cold regions, can effectively prevent metal corrosion caused by ice and salt, thus ensuring its use longevity and safety. [0003] Today, as environmental protection becomes more and more stringent, higher and higher requirements are put forward for the anti-fuel leakage performance of fuel tanks. HDPE fuel tanks are mainly divided into single-layer fuel tanks and multi-layer fue...
