Description
Technical Field
The invention relates to a modified nylon material, in particular to a modified nylon 610 material special for an alkaline zinc-manganese battery sealing ring.
Background
The existing materials for the alkaline battery sealing ring mainly comprise nylon 66 and nylon 612, and the nylon is heated, melted and processed into a certain shape by injection molding to be used as a sealing part of the alkaline battery. Nylon 66 and nylon 612 have respective problems in practical applications: the nylon 66 has high water absorption rate, so the water absorption rate of the nylon 66 is reduced after several times of heat treatment in use, but the physical and mechanical properties of the material are changed after the nylon is heated, the uniformity of the material is reduced, the battery is easy to leak in actual production application, and unnecessary damage caused by battery explosion sometimes can be caused; although the nylon 612 has low water absorption rate and good material uniformity, the material has good rigidity and poor toughness, and in practical application, the center hole of the sealing ring is easy to crack to cause liquid leakage, and the battery seal is not easy to form, so that certain defects exist. The mainstream materials used by the sealing ring in the market at present, including nylon 66 and nylon 612, are imported materials, and the domestic materials are few. The pure nylon 610 material has poor homogeneity and toughness, is not easy to be processed into a tiny sheet member (an alkaline battery sealing ring), and has mechanical properties which can not meet the requirements of the alkaline battery sealing ring, so the nylon 610 material is not used for manufacturing the alkaline battery sealing ring.
The invention patent of CN 102993736A discloses a halogen-free flame-retardant nylon 610 and polypropylene alloy composite material, which is composed of the following raw materials in parts by weight: 140-170 parts of nylon 610 resin; 39-51 parts of polypropylene resin; 17-28 parts of grafted polypropylene resin; 2.2-3.3 parts of a coupling agent; 50-65 parts of a filler; 35-52 parts of melamine urate; 0.9 to 1.7 portions of antioxidant; 77-92 parts of glass fiber; 0.5-0.9 part of surface modifier. The material is difficult to process into a tiny slice piece (an alkaline battery sealing ring), the processing performance is poor, meanwhile, a large amount of glass fibers and polypropylene resin are added into the material, the toughness of the material is overlarge, after the alkaline battery sealing ring is processed and assembled on a battery, the safety hole of the battery cannot be automatically broken due to overlarge toughness, the battery is easy to explode, and huge potential safety hazards exist.
Disclosure of Invention
The invention aims to provide a modified nylon 610 material special for an alkaline zinc-manganese battery sealing ring, which has the advantages of good material uniformity, compromise between rigidity and toughness, particularly suitable mechanical property for the requirement of the alkaline battery sealing ring, difficult fracture of a central hole of the prepared sealing ring, good material processability, easier forming in the battery sealing process on a production line and small damage to a die and a battery.
The technical scheme adopted by the invention for solving the technical problem is as follows:
a modified nylon 610 material special for an alkaline zinc-manganese battery sealing ring is prepared by mixing nylon 610 resin, an antioxidant, a lubricant and a stabilizer; the weight percentage of the nylon 610 resin is as follows: the addition amount of the antioxidant is 0.05-1.0%, the addition amount of the lubricant is 0.2-3.0%, and the addition amount of the stabilizer is 0.05-0.5%.
The modified nylon 610 material provided by the invention is used as a novel injection molding material for the alkaline battery sealing ring, is a material which meets the sealing and safety requirements of the alkaline battery sealing ring mainly by means of the inherent mechanical properties of nylon 610 resin with a specific molecular weight, and is formed by specifically modifying the material while meeting the processing requirements. The material performance is very close to that of nylon 612, but due to the difference of molecular structures, the material has some advantages relative to nylon 612 in application: the production is smoother, the center hole is not easy to break, a better sealing structure can be kept in the battery sealing process, and the battery is not easy to leak liquid to cause damage to electric appliances.
The nylon material is a polymer, and has different molecular weights from thousands to millions, and the properties are different. Aiming at the characteristics of the alkaline battery sealing ring, the invention adopts nylon 610 resin with specific molecular weight (the relative molecular weight range is 5000-20000) for modification, so that the mechanical property meets the specific requirements of sealing and safety of the alkaline battery sealing ring, and simultaneously, the antioxidant, the lubricant and the stabilizer are added in an auxiliary way, so that the processing property of the material and the homogeneity of the material are greatly improved. The addition amount of the antioxidant, the lubricant and the stabilizer is very important, so that the modified nylon 610 material which has good processing performance and uniformity and mechanical properties meeting the special requirements of sealing and safety of the alkaline battery sealing ring can be obtained.
Preferably, the nylon 610 resin has a relative molecular weight ranging from 5000 to 20000. The control of the molecular weight of the nylon 610 resin is an abnormal key, if the molecular weight is lower than 5000, the toughness is insufficient, and a central hole for manufacturing a battery sealing ring is easy to crack; if the molecular weight is higher than 20000, the toughness is too high, after the alkaline battery sealing ring is processed to be assembled on a battery, the safety hole of the battery cannot be automatically broken due to the too high toughness, the battery explosion is easily caused, and huge potential safety hazards exist.
Preferably, the antioxidant is selected from one or more of pentaerythritol tetrakis (beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate), tris (2, 4-di-tert-butylphenyl) phosphite, octadecyl beta- (3, 5-di-tert-butyl-4-hydroxyphenyl-propionate, dilauryl thiodipropionate, distearyl thiodipropionate and N, N' -bis- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionyl) hexanediamine.
Preferably, the lubricant is one or more selected from silicone powder, N' -ethylene bis stearamide, polytetrafluoroethylene wax and silicone master batch.
Preferably, the stabilizer is one or more selected from calcium stearate, barium stearate and zinc stearate.
The components of the antioxidant, the lubricant and the stabilizer are selected unconventionally, and the components of the antioxidant, the lubricant and the stabilizer are specifically selected according to the characteristics of mixing uniformity with nylon 610 resin, improvement on the performance of the nylon 610 resin, no decomposition at the temperature higher than the melting point of the nylon 610 resin and the like.
A preparation method of a modified nylon 610 material special for an alkaline zinc-manganese battery sealing ring comprises the following steps: the nylon 610 resin is firstly uniformly mixed with the antioxidant, the lubricant and the stabilizer, then the mixture is melted and extruded in a double-screw extruder at 230 to 250 ℃, and then the mixture is cooled and granulated.
The beneficial effects of the invention are:
the localization of the material for the alkaline battery sealing ring is realized, the sealing performance and the safety performance of the battery are improved, the defective rate in the production process of the battery is correspondingly reduced, and compared with nylon 612 and nylon 66 on the market, the material for the alkaline battery sealing ring has the following advantages:
1. the mechanical property and the dimensional stability are uniform and stable compared with nylon 66.
2. The battery produced by the product has better sealing property, leak resistance and safety than nylon 66.
3. The defective rate of the battery produced by the product is reduced relative to that of the nylon 612.
4. The material is smoother than nylon 612 in the process of producing the sealing ring by injection molding, and the production efficiency is improved.
