Abstract
The invention discloses a PFA (perfluoro(alkoxy alkane)) material which comprises PFA granules and an additive, wherein the additive comprises a carbon nanotube, fullerene, a weather-resisting agent, reinforcing filler, a flame retardant, a coupling agent and a crosslinking agent. The PFA material comprises the following components in parts by weight: 100 parts of the PFA granules, 15-20 parts of the carbon nanotube, 5-10 parts of the fullerene C540, 10-15 parts of the weather-resisting agent, 20-30 parts of the flame retardant, 15-20 parts of the reinforcing filler, 15-30 parts of the coupling agent and 10-20 parts of the crosslinking agent, wherein the weather-resisting agent comprises 7-10 parts of an antioxidant and 3-8 parts of a light stabilizer. The PFA material disclosed by the invention is good in processability, easy to use, low in wear rate, and low in maintenance difficulty, effectively prolongs the service life of equipment, and reduces the cost of application.

The English name of PFA is: Polyfluoroalkoxy, and Chinese is: and tetrafluoroethylene-perfluoro alkoxy vinyl ethers multipolymer (also known as: cross fluoroalkyl compound, soluble poly tetrafluoroethylene).
Oxidation inhibitor is also known as antioxidant, can suppress or delay plastics in manufacture, processing, application and storage, because of being heated, light, mechanical stress, electric field, the plastics caused by factor such as heavy metal ion contained by radiation and additive and the bad effect of products appearance and internal performance.It is of a great variety.The 5 large classes such as phenols, amine, P contained compound, sulfocompound and organic metal salt can be divided into by chemical structure.According to the different mechanism of action, phenols and amine are also called primary antioxidant, and the compound containing p and s is also called auxiliary anti-oxidant.The Active Radicals Produced produced in oxidative degradation is caught in the effect of primary antioxidant, thus interrupts chain type DeR, reaches anti-oxidant object.The effect of auxiliary antioxidant is that the intermediate product of oxidative degradation is decomposed into non-free radical product.Usually, main and auxiliary oxidation inhibitor use, reach best antioxidant effect by mutual synergistic effect.The Main way of oxidation inhibitor research improves antioxygen efficiency, persistence and consistency.
Photostabilizer can suppress or weaken the plastics photodegradation that causes or photoaging effect because absorbing UV-light, extends plastics and uses and the additive of storage life.Its mechanism is shielded from light source of radiation, absorbs and dissipate to cause the ultraviolet radiation of plastic degradation, or the excited energy on dissipation plastic molecules.Photostabilizer can be mixed in plastics are compounding.Conventional photostabilizer has: salicylate class, benzophenone, benzotriazole category, group-substituted acrylonitrile, triazines and organic complex class.
PFA is the multipolymer of a small amount of perfluoro propyl perfluoroalkyl vinyl ether and tetrafluoroethylene.Fusion bonding strengthens, and melt viscosity declines, and performance is unchanged compared with tetrafluoroethylene, so can directly adopt common thermoplastic's forming method to be processed into goods, improves the processibility of product.
PFA life-time service temperature-80-260 degree, has remarkable chemical resistance, all corrosion-resistant to all chemical, and has good wear resistance.
Carbon fiber nanotube can by with macromolecular material intermolecular bonding, in enhancing metallic substance, the effect of C540 by better than the carbon in coke, this is because C540 is less than the particle of carbon black, activity is higher, can the effectively mechanical property of strongthener and crocking resistance.
Carbon fiber nanotube is a kind of high-temperature fibre with very high strength and modulus, is the high-end kind of chemical fibre.Its proportion is less than 1/4 of steel, and carbon fiber resin composite material tensile strength is general all at more than 3500Mpa, and be 7 ~ 9 times of steel, tensile modulus of elasticity is that 23000 ~ 43000Mpa is also higher than steel.
In addition on carbon fiber nanotube owing to there is pentacyclic defect, enhance reactive behavior, under high temperature and other material existent condition, carbon nanotube is easily opened in end, forms a pipe, is filled formation matrix material by PFA.Such strength of materials is high, modulus is high, high temperature resistant, thermal expansivity is little, wear resistance and opposing thermal change performance all obtain significant strong.
