Abstract
The invention discloses a flexing-resistant nylon material for a cable jacket and a preparation method of the flexing-resistant nylon material. The flexing-resistant nylon material is prepared by, by weight, 30-45 parts of nylon 11, 223-36 parts of thermoplastic polyurethane elastomer, 15-25 parts of styrene-isoprene-butadiene terpolymer, 18-26 parts of nano diamond, 10-15 parts of basic sodium and aluminum carbonate, 17-24 parts of brominated epoxy resin, 3-6 parts of isocetyl palmitate, 5-10 parts of N,N-dimethyl-p-toluenesulfonamide, 8-14 parts of tributoxyethyl phosphate ester, 3-5 parts of magnesium oleate, 2-4 parts of stannous fluoborate, 4-8 parts of barium molybdate, 10-15 parts of PPTA pulp and 2.5-4.5 parts of assistant. The nylon 11 is taken as a main material, and the thermoplastic polyurethane elastomer and styrene-isoprene-butadiene terpolymer are added to perform blending modification on the nylon 11, so that flexing resistance and fatigue resistance of the flexing-resistant nylon material are improved.
Description
technical field [0001] The invention relates to a twist-resistant nylon material for a cable sheath and a preparation method thereof, belonging to the technical field of polymer material processing. Background technique [0002] Nylon (Nylon), scientific name polyamide fiber, English name Polyamide (referred to as PA), is the general term for thermoplastic resins containing repeated amide groups—[NHCO]—on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Family PA. Nylon has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, and has a low coefficient of friction, has certain flame retardancy, and is easy to process. There are many varieties of nylon, including PA6, PA66, PAll, PAl2, PA46, PA610, PA612, PAl010, etc., and widely used. With the rapid development of science and technology, the performance requirements for nylon materi...
