Abstract

The invention belongs to the technical field of macromolecule plastics, and particularly relates to a long-carbon-chain nylon pipe and a preparation method thereof. The long-carbon-chain nylon pipe is prepared from, by weight, 55-95 parts of long-carbon-chain nylon resin, 1-30 parts of a liquid plasticizer, 1-5 parts of an antioxidant, 1-5 parts of a lubricant and 1-4 parts of a light stabilizer. The long-carbon-chain nylon resin, the antioxidant, the lubricant and the light stabilizer are mixed and then added into a double-screw extruder, then the liquid plasticizer is added, and extrusion granulation is performed to obtain the long-carbon-chain nylon pipe. Various prepared hoses for automobiles have the strong toughness, can resist thermal oxidation, light oxidation, oil and the like, and are high in cost performance and suitable for being popularized on the national automobile market.

Description

technical field [0001] The invention belongs to the technical field of polymer plastics, and in particular relates to a long carbon chain nylon pipe material and a preparation method thereof. Background technique [0002] At present, long carbon chain nylon pipe materials are mainly used in the automotive industry and other fields, but the existing automobile oil pipes and brake pipes are all produced by imported nylon 11 and nylon 12, which are expensive and have a long delivery cycle. However, most of the existing domestic automobile oil pipes and brake pipes are produced with modified nylon 6, and the low temperature resistance cannot reach minus 40°C, and the oil resistance and zinc chloride resistance cannot meet the requirements. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a long carbon chain nylon pipe material and a preparation method thereof, which uses long carbon chain nylon as the m...
