Abstract
The invention discloses modified nylon which has excellent size stability, high toughness, high strength, high temperature resistance, and low water absorption rate, and is used for battery sealing ring. The modified nylon for a battery sealing ring is characterized in that raw materials are, by weight, 100% of nylon 610, 15% of toughening agent, 1% of antioxidant, 1% of antistatic agent, 1% of lubricant, 1% of anti-water anti-oil agent, and 8% of clay.
Description
Technical field
Because traditional nylon66 fiber water-intake rate is high, after the goods produced with nylon66 fiber absorb the product that water in air or be directly used in contacts with water, serious deformation can be produced, fatal the battery seal ring very high concerning precision requirement, also cause battery leakage thus, thus cause the potential safety hazard caused by battery.In order to solve potential safety hazard, producing battery producer and proposing requirements at the higher level to various material, wherein just comprising battery seal ring, in order to tackle the demand of downstream producer product, for this reason, our company develops this modification of nylon product for battery seal ring.
Background technology
Owing to using battery Frequent Accidents in actual life, producing battery producer requires more and more stricter to battery material, traditional nylon, namely the nylon66 fiber be polymerized by hexanodioic acid and hexanediamine can not meet actual requirement, based on this basis, our company's sebacic acid and hexanodioic acid be polymerized 610 to do modification, 610 raw materials and the main difference of conventional nylon 66 are environmental protection, high temperature resistant, low water absorption, and environmental protection meets the market mainstream; Because plastics are at high temperature easy to cause type to become, thus affect product use, for the battery seal ring that precision requirement is very high, if high temperature resistant bad, just easily produce deformation, once generation deformation, battery leakage will be caused, thus initiation battery explosion injures life and property safety problem.
Summary of the invention
For battery seal ring, there is the modification of nylon of outstanding dimensional stability, high tenacity, high strength, high temperature resistant, low water absorption, it is characterized in that, its raw material composition and weight proportion are: NYLON610 100%, toughner 15%, oxidation inhibitor 1%, static inhibitor 1%, lubricant 1%, water and oil repellent agent 1%, clay 8%.
NYLON610: traditional nylon is polymerized by hexanodioic acid and hexanediamine, and our company is polymerized by sebacic acid and hexanodioic acid with nylon, this material has the features such as high temperature resistant, water-intake rate is low, so with the product of this modified nylon, there is high temperature resistant and that dimensional stability is high physical property.
toughner: be a kind of high workability of being produced by reactive extrusion technology, unformed maleic anhydride functional ethylene copolymer, its completely saturated main refining brings outstanding heat and oxidative stability, thus weathering resistance is strengthened, its unformed property, adding on nylon material makes it under extremely low temperature condition, still have shock resistance, select special toughner, the optimum balance provided in nylon mixture between rigidity and low temperature is provided, modified nylon product is made to have high notched izod impact strength, improve the flexibility of nylon, reduce the susceptibility of humidity, improve the stability of size.
oxidation inhibitor: utilize high-end hydrolysis phosphite oxidation inhibitor and Hinered phenols antioxidant combination thus low volatility under improving further the high-temperature stability of NYLON610 and high temperature; and the stability of the polymkeric substance in atmosphere of excellence; the anti-yellowing change of course of processing brilliance and high temperature degradation protection, have outstanding processing and long-term stability.
Static inhibitor: our company's permanent antistatic agent, a certain proportion of permanent antistatic agent is added in nylon, all static inhibitor is distributed in nylon product, anlistatig place is made to define the antistatic net of cobweb effect, and these antistatic electrical networks formed are once formation, just be not easy to be destroyed, thus make goods have well lifelong antistatic effect.
Lubricant: this lubricant can not only improve the luminance brightness of product surface, strengthen the mobility of finished product, also there is the demoulding, damp proof, anti-precipitation, fouling resistance simultaneously, antistatic, dispersion performance good, thus reduce goods processing temperature, reduce screw torque, reduce wear and tear in machines, improve machine service life, play a role in energy conservation.
Water and oil repellent agent: use water and oil repellent agent, 1 kilogram of water and oil repellent agent is added in modification of nylon, nylon chemical resistance can not only be improved, also because this material and nylon uncompatibility, thin film is formed between nylon material and forcing machine, extremely low to metal adhesion, there is the character of releasing agent, thus make melt extrusion can be quick, smoothly, move equably, avoid the viscous effect that nylon and metal directly contact generation, thus improve processing characteristics, improve production capacity. because this material also has gesture potential difference characteristic, the film that nylon surface forms one deck wear resistance is moved under melting state, thus play the effect of waterproof and oilproof.
Clay: only have because general nylon is high temperature resistant between 70---80 degree, if the clay adding 5---10 part at modified nylon material, can make that nylon is high temperature resistant to be brought up on 90 degree.
