Embodiment 1

[0066] The content of talc in Examples 1 to 3 is 10% by weight of the weight of the outer main body layer, and the content of talc in Examples 4 and 5 is 15% by weight of the weight of the outer main body layer, while in Comparative Example 1 and Comparative Example 2 there is no Contains talc. The fuel tank of Example 1 had a thickness of 5.4 mm, and the fuel tanks of Examples 2 to 5 had a reduced thickness (as described above). The constituent ratios in Table 1 refer to the ratio of the thickness of the outer main body layer 12 to the total thickness of the fuel tank.

[0067] A side impact test was performed as an impact resistance test for the above-mentioned fuel tank 1 to measure the intrusion amount of the cylindrical portion. The value of Comparative Example 1 is set to 100, and the values ​​of the respective examples are shown in Table 1. In the side impact test, the amount of intrusion increases as the thickness of the fuel tank decreases, but this intrusion is onl...

Abstract

The fuel tank for automobiles has the following structure. A main body of a fuel tank has an entire thickness of 3 to 8 mm and is formed of a surface layer, an outer main body layer, an outer adhesive layer, a barrier layer, an inner adhesive layer, and an inner main body layer that are formed in this order from-exterior. The surface layer and the inner main body-layer are formed from high density polyethylene. The outer main body layer is formed by using as a main material a recycled material of high density polyethylene, contains an inorganic filler having a particle diameter of 10 mum or less in an amount of 10 to 35 wt percentage with respect to a total weight of the outer main body layer, and has an thickness of 25percentage to 50percentage of the entire thickness of the main body. The outer adhesive layer and the inner adhesive layer is formed from a synthetic resin having an adhesion property for both of high density polyethylene and the barrier layer, and the barrier layer is formed from a synthetic resin hardly or never allow fuel permeation.

Description

technical field [0001] The present invention relates to a fuel tank made of thermoplastic synthetic resin, and more particularly, the present invention relates to a fuel tank having a main body obtained by carrying out a synthetic resin part having a synthetic resin layer of a multilayer structure Formed by blow molding. Background technique [0002] For the structure of fuel tanks of motor vehicles and the like, fuel tanks made of metal have been used heretofore. However, fuel tanks made of thermoplastic synthetic resins have come into use in recent years because thermoplastic synthetic resins do not rust and are easily formed into desired shapes. [0003] Since blow molding is easy to form a hollow body, it is often used to produce synthetic resin fuel tanks for motor vehicles. Using the blow molding method, a fuel tank for motor vehicles is obtained by extruding a parison of a molten thermoplastic synthetic resin part while forming the parison into a cylindrical shape, ...
