Fuel tank material with high corrosion resistance

Abstract

The invention provides a fuel tank material with high corrosion resistance, and belongs to the technical field of automotive material preparation. The fuel tank material is prepared from the followingraw materials in percentage by weight: 20-40% of linear low density polyethylene resin, 5-10% of high density polyethylene resin, 1-5% of polypropylene resin, 1-4% of a high molecular lubricant, 0.5-5% of zinc oxide, 0.1-1% of stearic acid, 0.1-3% of a cross-linking agent, 1.5-4% of EVA modified resin, 0.1-0.5% of carbon black, 1.5-3% of zinc oxide, 2-3.5% of an antioxidant, 0.3-1% of lead stearate, 0.5-1% of a colorant, andthe balance of water. According to the fuel tank material, the components are novel, whilethe advantages of self-lubricationand the friction-resisting property of the polyethylene resinare kept, by introducing the modified resin component, the water lubrication friction property of the polyethylene resin is improved, at the same time, flexibility of the material is further improved, by introducing the antioxidant, oxidation resistance of the material is further improved, and particularly the polyethylene resin is suitable for use of the high friction resistance fuel tank material.

Description

technical field [0001] The invention belongs to the technical field of automobile material preparation and relates to a fuel tank material, in particular to a fuel tank material with high corrosion resistance. Background technique [0002] Traditional metal fuel tanks are gradually being replaced by lightweight, cheap, and easy-to-process plastic fuel tanks due to their shortcomings such as expensive, bulky, and difficult to process. This is because plastic fuel tanks are light in weight, acid / alkali corrosion resistant, rust-free, and can make full use of the body Space, can rebound by itself after encountering impact without permanent deformation, and will not generate electric sparks and cause explosion accidents during abrasion or impact. The plastic fuel tank has a long service life, low manufacturing cost, and secondary processing. The quantity is small, and due to the large degree of freedom of shape, the fuel tank can be made larger in the set space, but the defect o...

[0002] Traditional metal fuel tanks are gradually being replaced by lightweight, cheap, and easy-to-process plastic fuel tanks due to their shortcomings such as expensive, bulky, and difficult to process. This is because plastic fuel tanks are light in weight, acid / alkali corrosion resistant, rust-free, and can make full use of the body Space, can rebound by itself after encountering impact without permanent deformation, and will not generate electric sparks and cause explosion accidents during abrasion or impact. The plastic fuel tank has a long service life, low manufacturing cost, and secondary processing. The quantity is small, and due to the large degree of freedom of shape, the fuel tank can be made larger in the set space, but the defect of the plastic fuel tank is that gasoline will leak out from the wall of the fuel tank. In order to prevent this phenomenon, more materials are required. Multi-layer and thickened fuel tanks will virtually increase the fuel tank materials used by car companies. Not only must the materials be considered to prevent leakage, but also corrosion resistance, oxidation resistance, and light weight must be considered.
