Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of high polymer materials, and particularly relates to a high-performance nylon material and a preparation method thereof. BACKGROUND

[0002] Nylon is a kind of polyamide thermoplastic resin, also known as PA, which is widely used in engineering plastics and synthetic fibers and other fields due to its high strength, wear resistance, impact resistance and other characteristics, especially in mechanical parts such as bearings, supports, gears, etc. Nylon is widely used due to its lightweight, corrosion resistance and other characteristics.

[0003] Outdoor bearings and supports for wind power equipment are subjected to dynamic load and extreme temperature environment for a long time, and higher requirements are put forward for the material performance. The main materials used for outdoor bearings and supports at present include glass fiber reinforced nylon, specifically polyamide 66, abbreviated as PA66, which is a semi-transparent or opaque milky white bag or yellow granular crystalline polymer, and has good mechanical properties, toughness, self-lubricating property, wear resistance, chemical resistance and other advantages.

[0004] Since the specific strength and Young's modulus of glass fiber are much greater than those of PA66, the linear expansion coefficient is about 1 / 20 of that of PA66, the water absorption rate is almost zero, and the heat resistance and chemical corrosion resistance are good. The prior art usually uses a coupling agent such as polysiloxane to prepare PA66 modified by glass fiber, which effectively improves the material rigidity, impact strength, wear resistance and high temperature resistance, and is used as a lightweight metal substitute for precision bearings and other parts.

[0005] CN110838232A discloses a new type of nylon bearing retainer, which uses PA66 and PA6 as the main polyamide resin material, polytetrafluoroethylene as the wear-resistant agent, and glass fiber as the reinforcing fiber to obtain a new type of nylon material with good tensile strength, reduced wear and heat generation, and resistance to thermal expansion and cold shrinkage. However, bearings and supports used outdoors have problems such as long-term creep and ultraviolet aging based on special application environment, and long-term outdoor use may cause continuous load deformation and brittle material defects, resulting in further shortening of the service life of the material or safety problems.

[0006] In summary, the structure of the engineering plastic bearing support is relatively complex, and in the working condition of the bearing in the outdoor environment, the injection molding material not only requires good flowability, low shrinkage and small product deformation, but also should have good mechanical properties, especially good impact strength, low wear, high temperature and humidity resistance, weather resistance and other properties, which puts forward higher performance requirements for nylon materials. SUMMARY

[0007] Therefore, the present application aims to solve the problem that the performance of the nylon material for outdoor precision bearing in the prior art does not meet the expected effect, and provides a high-performance nylon material and a preparation method thereof, which meets the performance required by the application scene of the workpiece, including low friction coefficient, low wear, high strength and high modulus, long-period weather resistance retention rate, and long-period high-temperature and high-humidity performance retention rate, etc.

[0008] To achieve the above purpose, the present application proposes the following technical solutions:

[0009] A high-performance nylon material, specifically comprising the following components by weight:

[0010] Polyamide 66: 30-65 parts;

[0011] Special nylon resin: 5-25 parts;

[0012] Glass fiber: 30-35 parts;

[0013] Antioxidant: 0.2-0.4 parts;

[0014] Lubricant: 0.4-0.8 parts;

[0015] Compatibilizer: 1-3 parts;

[0016] Wear-resistant aid: 5-15 parts;

[0017] Weathering aid: 0.6-1.0 parts;

[0018] Black masterbatch: 0.3-0.7 parts.

[0019] Preferably, a high-performance nylon material, specifically comprising the following components by weight:

[0020] Polyamide 66: 35-45 parts;

[0021] Special nylon resin: 20-25 parts;

[0022] Glass fiber: 30-35 parts;

[0023] Antioxidant: 0.3-0.4 parts;

[0024] Lubricant: 0.5-0.8 parts;

[0025] Compatibilizer: 2-3 parts;

[0026] Wear-resistant aid: 10-15 parts;

[0027] Weathering aid: 0.8-1.0 parts;

[0028] Black masterbatch: 0.5-0.7 parts.

[0029] Further preferably, a high-performance nylon material specifically includes the following components by weight:

[0030] Polyamide 66: 35.5 parts;

[0031] Special nylon resin: 20 parts;

[0032] Glass fiber: 35 parts;

[0033] Antioxidant: 0.3 parts;

[0034] Lubricant: 0.5 parts;

[0035] Compatibilizer: 2 parts;

[0036] Wear-resistant aid: 10 parts;

[0037] Weathering aid: 1 part;

[0038] Black masterbatch: 0.7 parts.

[0039] Further, the nylon resin is one or a mixture of one or more of PA6I, PA610, PA612, and PAMXD6.

[0040] Specifically, polyamide 66, abbreviated as PA66, is polyhexamethylene adipamide, which is obtained by polycondensation of adipic acid and hexamethylene diamine; PA6I, i.e. nylon 6I, is m-phenylene isophthalamide hexamethylene diamine and fiber; PA610, i.e. nylon 610, is polyhexamethylene sebacamide; PA612, i.e. nylon 612, is polyhexamethylene dodecanamide; and PAMXD6, i.e. nylon MXD6, is poly-m-xylylenediamine adipamide.

[0041] Further, the special nylon resin includes PA6I, PA610, or PA612, and a mixture of PAMXD6, wherein the weight ratio of PA6I, PA610, or PA612 to PAMXD6 is 1:(3-5).

[0042] Preferably, the nylon resin includes a mixture of PA6I, PA610, or PA612 and PAMXD6, wherein the weight ratio of PA6I, PA610, or PA612 to PAMXD6 is 1:4.

[0043] Specifically, PA6I, PA610, or PA612 and PAMXD6 are compounded in a weight ratio of 1:4, which synergistically acts with polyamide 66 to effectively reduce the water absorption of the material and ensure the strength retention rate of the material during use.

[0044] Further, the glass fiber is hydrolysis-resistant alkali-free short-cut glass fiber, with a short-cut length of 3-4.5 mm, a fiber diameter of 9-11 μm, and a special silane-type impregnant coated on the surface.

[0045] Further, the antioxidant includes one or more than one of 1098, 168, H10 and H318.

[0046] Preferably, the antioxidant includes 1098, H10 or H318, and a compound of 168.

[0047] Further preferably, the weight ratio of 1098, H10 or H318 and 168 is 2:1.

[0048] Specifically, the antioxidant 1098 is a hindered phenolic antioxidant, and the phenolic hydroxyl group in the molecular structure thereof can provide hydrogen atoms to react with active free radicals generated by the high polymer material under the action of heat, light or mechanical stress, to generate stable free radical intermediates, thereby blocking the free radical chain reaction.

[0049] The antioxidant 168 is a phosphite antioxidant, and the phosphite group thereof can react with hydroperoxide generated in the oxidation process of the high polymer material, to reduce the hydroperoxide into stable alcohol, while being oxidized into phosphate itself, thereby preventing the generation of free radicals.

[0050] The antioxidant H10 is a hindered phenolic antioxidant, and the phenolic hydroxyl group in the molecular structure thereof can provide hydrogen atoms to react with free radicals generated by the high polymer material under the action of heat, oxygen or ultraviolet light, to generate stable phenoxyl radicals, thereby terminating chain growth, in addition, the phenoxyl radicals cannot continue to participate in chain reaction due to the steric hindrance effect and conjugate stabilization of the tert-butyl group, thereby effectively blocking the oxidation process, and H10 can provide multiple active sites, and has better antioxidant effect, and due to the larger molecular weight, it has long-term aging resistance, weather resistance, long-term stability and high temperature resistance.

[0051] The antioxidant H318 is a high steric hindrance phenolic antioxidant, and the phenolic hydroxyl group in the molecular structure thereof can provide hydrogen atoms to react with free radicals generated by the high polymer material under the action of heat, oxygen or ultraviolet light, to generate stable phenoxyl radicals, thereby terminating chain growth, in addition, the generated phenoxyl radicals cannot continue to participate in chain reaction due to the protection of the large steric hindrance group (tert-butyl), but are stabilized by resonance structure to prevent further oxidation, and H318 can provide multiple active sites, and has better antioxidant efficiency, and forms high steric hindrance through the structure connected by the benzene ring center, thereby having persistent antioxidant and high temperature resistance.

[0052] In summary, the hindered phenolic antioxidant interrupts the oxidation chain reaction by capturing free radicals, preventing the breakage and crosslinking of polymer chains, thereby maintaining the molecular weight and structural integrity of the nylon. The phosphite antioxidant prevents the initiation of new free radical chain reactions by decomposing hydroperoxides. The combination of antioxidant 1098, H10 or H318 and antioxidant 168 can simultaneously exhibit both free radical scavenging and hydroperoxide decomposition effects. The free radicals are captured to prevent their participation in the oxidation cycle, and the still active hydroperoxides generated during this process are decomposed to prevent automatic oxidation. At the same time, the generation of free radicals is inhibited and delayed, significantly improving the antioxidant effect and making it more suitable for the processing needs of high-precision bearing parts.

[0053] Further, the lubricant is at least one of modified ethylene bis fatty acid amide, silicone master batch, and zinc stearate.

[0054] Further, the compatibilizer is at least one of maleic anhydride grafted PE, maleic anhydride grafted POE, and maleic anhydride grafted SEBS.

[0055] Further, the wear-resistant aid is at least one of polytetrafluoroethylene, ultra-high molecular weight polyethylene, and molybdenum disulfide.

[0056] Further, the weather-resistant aid includes one or more than one combination of benzotriazole ultraviolet stabilizer and hindered amine light stabilizer.

[0057] Preferably, the weather-resistant aid includes a combination of benzotriazole ultraviolet stabilizer and hindered amine light stabilizer.

[0058] Further preferably, the weight ratio of benzotriazole ultraviolet stabilizer to hindered amine light stabilizer is 1:1.

[0059] Specifically, the benzotriazole ultraviolet stabilizer includes anti-UV agent 234, abbreviated as UV-234, which is a high molecular weight benzotriazole light absorber that can absorb ultraviolet light. The unabsorbed ultraviolet light waveband will continue to damage the high polymer to form free radicals and continuously damage the high polymer. The hindered amine light stabilizer includes UV agent 944, abbreviated as UV-944, which is a hindered phenolic ultraviolet stabilizer that can inactivate active free radicals to meet long-term weathering requirements.

[0060] In summary, the benzotriazole ultraviolet stabilizer reduces the damage of ultraviolet to the polymer by absorbing ultraviolet radiation and converting it into heat energy; the hindered amine light stabilizer interrupts the degradation chain reaction of the polymer by capturing free radicals generated by light. The use of the above two weathering aids in combination can produce a synergistic effect through the dual protection mechanism of absorbing ultraviolet and capturing free radicals, greatly improving the use effect, while having excellent absorption efficiency in the wavelength range of 200-400 nm, expanding the ultraviolet protection range, significantly improving the weather resistance of the nylon material in outdoor environment, and prolonging its service life.

[0061] Meanwhile, the weathering aid compound used in the present application will not be affected by the antioxidant compound, ensuring the compatibility of the compound while achieving the synergistic effect of antioxidants and weathering aids. Specifically, the addition of antioxidants prevents degradation of the material during processing and slows down aging decay during use; the use of weathering aids protects the color change of the product under outdoor light and prevents performance decay, both of which have compatibility, ensuring the stability of the product during use through synergistic effect, so that the antioxidant-related properties and weather-related properties of the nylon material are significantly improved.

[0062] Further, the black masterbatch includes a carrier-free inorganic color masterbatch.

[0063] A preparation method of a high-performance nylon material, comprising the following steps:

[0064] S1, polyamide 66, special nylon resin, antioxidant, lubricant, compatibilizer, wear-resistant aid, weathering aid and black masterbatch are weighed according to the weight percentage, mixed uniformly in a mixer, and a mixture is obtained;

[0065] S2, the mixture prepared above is added to the main feeding port of the double screw extruder, glass fibers are added to the side feeding machine bin of the double screw extruder, and after melt blending, extrusion, drawing, traction and granulation, the high-performance nylon material is obtained.

[0066] Preferably, in step S1, the uniform mixing is dry mixing for 5-10 min in a low-cost mixer.

[0067] Preferably, in step S2, the double screw extruder is set to an extrusion temperature of 260-280℃ and a screw rotation speed of 300r / min.

[0068] The present application has the following advantages:

[0069] The application effectively reduces the water absorption of the nylon material through reasonable compounding, ensures the material flowability and easy processing, improves the performance retention rate in use, inhibits and delays the generation of free radicals through reasonable compounding of antioxidants, significantly improves the antioxidant effect, and greatly improves the persistent antioxidant, aging resistance, long-acting stability, high-temperature resistance and other properties of the material; the weather resistance of the nylon material in outdoor environment is significantly improved through reasonable compounding of weather resistance additives, the service life is prolonged, through the synergistic effect of the above components, a high-performance nylon material with high stability for outdoor precision bearings is obtained, and the material has low friction coefficient, low wear, high strength and modulus, long-period weather resistance and long-period high-temperature and high-humidity resistance and other excellent properties.
