Problems solved by technology

[0002] Traditional metal fuel tanks are gradually being replaced by light, cheap, and easy-to-process plastic fuel tanks due to their shortcomings such as expensive, bulky, and difficult to process. At present, plastic fuel tanks are basically blow-molded, and the efficiency of blow-molding processing is low, resulting in a lot of corner waste , based on the shortcomings of metal fuel tanks and blow-molded plastic fuel tanks, the current domestic injection molding fuel tank materials are still blank

Abstract

The invention discloses a material for producing an injection molding oil tank and a manufacturing method thereof. A material comprises the following raw materials in parts by weight: 48-68 parts of linear low-density polyethylene resin, 12-32 parts of high-density polyethylene resin, 5-15 parts of polypropylene resin, 5-15 parts of a saturated ethylene-octene copolymer, 0.1-0.2 part of a nucleating agent, 0.4-0.6 part of an antioxidant, 0.3-0.7 part of a lubricating agent and 0.1-0.5 part of carbon black. Due to the adoption of the material for the injection molding oil tank, the problems of air tightness, oil resistance, stress cracking resistance, cold resistance and the like are solved.

Description

technical field [0001] The invention relates to an oil tank, in particular to a material for producing an injection-molded oil tank and a manufacturing method thereof. Background technique [0002] Traditional metal fuel tanks are gradually being replaced by lightweight, cheap, and easy-to-process plastic fuel tanks due to their disadvantages of being expensive, bulky, and difficult to process. At present, plastic fuel tanks are basically blow-molded, and the blow-molding processing efficiency is low, resulting in a lot of corner waste , based on the shortcomings of metal fuel tanks and blow-molded plastic fuel tanks, the current domestic injection molding fuel tank materials are still blank. [0003] In view of this, in view of the above problems, a material for producing injection-molded fuel tanks that effectively improves the above-mentioned deficiencies is proposed, and at the same time, a manufacturing method for the material is introduced. Contents of the invention ...
