Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of data lines, and particularly relates to a low-temperature-resistant and bend-resistant data line and a preparation method thereof. BACKGROUND

[0002] With the continuous development of the electronic industry, data lines, as a connecting medium between electronic devices and electronic devices or power supplies, have become an indispensable part of our lives. Traditional data lines are mostly made of PVC or silicone. When frequently bent or subjected to external force impact, they are prone to breakage due to material aging and brittleness, which not only seriously affects user experience, but also causes resource waste and environmental pollution. In addition, cracks generated by repeated bending can greatly shorten the service life of the data line and increase the replacement frequency. In comparison, TPU material has excellent elasticity, toughness, environmental friendliness and good durability when used as data line material, and has good application prospects.

[0003] However, ordinary TPU has obvious defects, such as low oxygen index, flammability and serious melt dripping phenomenon during combustion, which greatly limits its use range. In addition, although ordinary TPU has certain anti-aging properties, with the continuous improvement of actual application requirements, its anti-aging properties have been difficult to meet the current needs. Therefore, it is of great practical significance and application value to develop a low-temperature-resistant and bend-resistant data line with excellent performance. SUMMARY

[0004] In order to solve the above technical problems, the application provides a low-temperature-resistant and bend-resistant data line and a preparation method thereof.

[0005] The purpose of the application can be achieved by the following technical solutions: A low-temperature-resistant and bend-resistant data line and a preparation method thereof, comprising the following raw materials by weight: TPU 45-65 parts, polypropylene 8-12 parts, ethylene propylene diene rubber 15-25 parts, plasticizer 10-12 parts, modified flame retardant 10-16 parts, modified anti-aging agent 1-2 parts, lubricant 1-2 parts, and coupling agent 1-2 parts. The plasticizer is white oil. The lubricant is stearic acid. The coupling agent is KH-550.

[0007] The modified anti-aging agent is prepared by the following method: Step B1: mix hydroxybenzophenone, 1-oxiranylmethyl-3,5-diallylisourea, and chloroform, then add Amberlyst-15 ion exchange resin, heat to 55°C in an ultrasonic water bath for 4-5 h, after the reaction is completed, filter, rotary evaporate, and dry in vacuum to prepare an intermediate; Further, the amount ratio of hydroxybenzophenone, 1-oxiranylmethyl-3,5-diallylisourea, chloroform, and Amberlyst-15 ion exchange resin is 0.01-0.03 mol: 0.01-0.03 mol: 5 mL: 0.8-1.0 g; The intermediate is prepared by reacting the hydroxyl group of hydroxybenzophenone and the epoxy group of 1-oxiranylmethyl-3,5-diallylisocyanurate; In step B2, N-phenylmaleimide and benzoyl peroxide are uniformly dispersed in xylene, and then the intermediate is added and uniformly stirred; under nitrogen protection, the mixture is heated to 90 DEG C for 4.5 hours; vacuum distillation, cooling, washing, filtration and vacuum drying are performed to obtain the modified anti-aging agent. Further, the amount ratio of N-phenylmaleimide, benzoyl peroxide, xylene and the intermediate is 0.01-0.03 mol: 0.16 g: 50-60 mL: 0.01-0.03 mol. Finally, the modified anti-aging agent is prepared by copolymerization of the intermediate and the carbon-carbon double bond of N-phenylmaleimide.

[0008] A preparation method of a low-temperature bending-resistant data line, specifically comprising the following steps: S1, TPU, polypropylene and ethylene-propylene-diene rubber are mixed and uniformly stirred at a rotating speed of 500-700 rpm, and then plasticizer, modified flame retardant, modified anti-aging agent, lubricant and coupling agent are added and mixed and stirred at a rotating speed of 200-400 rpm for 30 min to obtain a mixture; S2, the mixture is put into a double-screw extruder and melt-extruded at 180-200 DEG C to obtain the low-temperature bending-resistant data line.

[0009] The present application has the following advantages: The low-temperature bending-resistant data line has good flame-retardant effect, excellent anti-aging effect and long service life.

[0010] The modified flame retardant prepared by the present application realizes high-efficiency flame retardation and environmental protection through phosphorus-oxygen-silicon synergistic flame retardation; the phosphorus component generates a phosphate protective layer during combustion to insulate oxygen and promote charring, thereby inhibiting flame spread; the nitrogen component releases non-combustible gas to dilute the concentration of combustible gas and interrupt the combustion chain reaction; the high-bond-energy Si-O bond and phosphorus-oxygen double bond of the silicon component synergistically improve the thermal stability and tensile strength of the material; in addition, the gamma-glycidyloxypropyltrimethoxysilane can promote the formation of a dense carbonized layer on the surface during combustion, thereby inhibiting heat transfer and oxygen diffusion, delaying the combustion process and reducing smoke generation; furthermore, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, as a phosphaphenanthrene compound with high thermal stability, promotes the formation of a dense and continuous carbon layer during combustion to insulate oxygen and heat, and synergistically enhances the flame-retardant effect with the phosphorus-oxygen double bond to prolong the service life; in addition, the modified flame retardant prepared by the present application is halogen-free, which helps to reduce pollution to the environment and damage to the ecosystem and is harmless to human health, thereby realizing sustainable development. The modified anti-aging agent prepared by the application has the advantages of macromolecular polymer, and exhibits performance beyond traditional small molecule anti-aging agents. The hydroxybenzophenone in the modified anti-aging agent is excited to a high energy level by the electronic transition effect of the benzene ring and the methoxy group when irradiated by ultraviolet light, and then releases energy by emitting weak long waves, effectively resisting high-energy ultraviolet light. At the same time, it can absorb ultraviolet light and convert it into harmless heat energy, reducing the photodegradation of molecular chains and protecting materials from ultraviolet damage. In addition, the maleimide group improves the glass transition temperature and melting point of the material by enhancing the intermolecular force, giving the molecular chain rigidity and heat resistance, and reducing the influence of high-temperature thermal aging. In addition, the six-membered ring structure of 1-oxirane methyl-3,5-diallyl isocyanurate has no active hydrogen, giving the isocyanurate ring good thermal stability and hydrolysis stability, enhancing the antioxidant capacity, and improving the heat resistance of the material. In cooperation with N-phenyl maleimide, the possibility of material yellowing due to high temperature is reduced. DETAILED DESCRIPTION
