Modified nylon polyamide 6 (PA6) material for automobile oil pipe and preparation method of modified nylon PA6 material

Abstract

The invention discloses a modified nylon polyamide 6 (PA6) material for an automobile oil pipe, which is prepared from the following raw materials based on parts by weight: 100-110 parts of nylon PA6, 5-10 parts of ethylene propylene diene monomer 4903, 10-12 parts of polybutylece terephthalate (PBT), 3-5 parts of polycaprolactone, 10-15 parts of active calcium, 5-10 parts of nano argil, 1-2 parts of anti-aging agent NBC, 1-2 parts of anti-aging agent MB, 3-5 parts of N-(beta-aminoethyl)-gamma-aminopropyl trimethyl (ethyl) oxysilane, 1-2 parts of dicumyl peroxide (DCP), 1-2 parts of isopropyl bistearoyloxy aluminate, 1-2 parts of modified antioxidant 168, 15-20 parts of modified tree ash, 1-2 parts of antioxidant DLTP, 1-2 parts of adipic acid propylene glycol polyester, 1-2 parts of dioctyl maleate and 3-5 parts of zinc stearate. The antioxidant 168 and the tree ash are added into the modified nylon PA6 material for modification, so that the impact resistance, the toughness and the tensile strength of the nylon material are improved, and the material cost is reduced; and the modified nylon PA6 material has the advantages of good chemical resistance, permeability resistance and wear resistance, excellent size stability, high impact resistance and tensile strength and the like, and is hard to break, thus meeting the demand of the automobile oil pipe.
