Description

A kind of mineral strengthen high-performance PPA material and preparation method thereof
Technical field
The present invention relates to technical field of polymer materials, relate in particular to a kind of mineral and strengthen high-performance PPA material and preparation method thereof.
Background technology
Polyphtalamide (Polyphthalamide, PPA) is the semiaromatic polyamide composition taking terephthalic acid or phthalic acid as raw material.PPA is a kind of hemicrystalline thermoplasticity aromatic polyamide, is commonly called as aromatic series high-temperature nylon, and it is a kind of resistant to elevated temperatures material, and fusing point is between 310～325 DEG C.PPA has following fundamental characteristics: 1, as more solid in PA66 hard than fats polymeric amide; 2, lower to the susceptibility of moisture, thermal characteristics is better; 3, resistance to creep, fatigue and chemical resistance are outstanding; 4, the PPA resin of glass strengthening has very high heat-drawn wire (Heat Deflection Temperature, HDT) value, can tolerate the very shortterm effect of high-temperature; 5,, under home condition, PPA resin shows outstanding non-fusibility to aliphatic hydrocarbon, aromatic hydrocarbon, hydrochloric ether, ester, ketone, alcohol and most of aqueous solution conventionally.
Under humid tropical condition, the tensile strength of PPA is higher by 20% than nylon 6, higher than nylon 66; The modulus in flexure of PPA material is higher by 20% than nylon, and hardness is larger, can resist long tensile creep; And the ability of resistance to gasoline, grease resistance and the refrigerant of PPA is also strong than PA; PPA has superior environmental-protecting performance, can reach U.S. FDA level.The water-intake rate of PPA is more much lower than general enhancing PA6 or PA66, even soak in cold water several years, its tensile strength also can keep more than 80%.
Polymeric amide all absorbs certain moisture, causes that plastification and size change.For example PA66, it when relative humidity is 100%, can absorb 8～9% moisture at-5 DEG C, and this makes its second-order transition temperature (Tg) drop to-20 DEG C by 6.5 DEG C, and size increases by 2～3%.Poor because of its dimensional stability, processing is difficulty comparatively, has limited its use range.And higher, the ageing-resistant weak effect of the price of existing MODIFIED PP A material.
