Description
Technical field：
The present invention relates to technical field of polymer materials, more particularly to a kind of filled with rapid crystallization to enhance polyphenylene sulfide
Ether composite material.
Background technology：
Polyphenylene sulfide (PPS) is also known as polyphenylene sulfide, poly- phenylene thioether, and nineteen sixty-eight is by U.S. Phillips Petroleum
Co. a kind of new special engineering plastics initiated and gone into operation.Due to the presence of a large amount of phenyl ring on PPS main chains, material is increased
Rigidity so that unmodified polyphenyl thioether material brittleness is bigger, and mechanical performance is poor, and heat resisting temperature is relatively
It is low, thus the application of material is greatly limited.Using glass fibre or inorganic mineral filler material come modified polyphenyl thioether
Its mechanical performance and heat resistance can be improved, heat distortion temperature can reach 260 DEG C.
Since its molecular structure particularity makes it with many unique performances, it is mainly manifested in：Excellent thermostabilization
Property, the physical and mechanical property of chemical stability, dimensional stability, corrosion resistance and excellent electrical property, good adhesive property,
Excellent anti-flammability, good electrical property, can blending and modifying.At present automobile making, electric, chemical industry, instrument and meter and
Aerospace industry etc. has a wide range of applications.
However, since polyphenyl thioether material self character determines that it requires mold temperature big in injection molding process
In 130 DEG C, the time long enough of injection molding can ensure the performance of material, otherwise the intensity and heat resistance of material by
It influences.However limited at present by former, many enterprises are it is difficult to ensure that the temperature of mold reaches 130 DEG C.Just because of polyphenyl
The shortcomings of that there are crystalline rates in molding process is slow for sulfide material, and mold temperature is high, and molding cycle is long, in certain journey
The application of polyphenyl thioether material is limited on degree.
With the continuous expansion of the purposes of polyphenyl thioether material, the especially application on electronic apparatus, component of machine,
More and more enterprise requirements improve the processing performance of polyphenylene sulfide, and the performance of polyphenyl thioether material can not meet requirement at present
, therefore it is required that developing, crystalline rate is fast, and molding die temperature requirement is low, short molding cycle polyphenyl thioether composite material.
Invention content：
The purpose of the present invention is for disadvantage present on the prior art, poly-p-phenylene sulfide ether material carries out glass and mineral increase
