Description
One, technical field
The present invention relates to a kind of self lubricating wear resistant polyaryl thioether and preparation method thereof, belong to the polymer composite preparation field.
Two, background technology
Poly arylidene thio-ester comprises a big class sulfur-bearing aryl polymer, as polyphenylene sulfide, PPSS, polyphenylene sulfide ketone and polyphenylene sulfide acid amides etc., wherein, in beginning large-scale industrial production in 1973, it was a kind of special engineering plastics of excellent combination property to polyphenylene sulfide, have high temperature resistant, corrosion-resistant, radiation hardness, do not fire, nontoxic, mechanical property and electrical property be very excellent, the dimensional stability of goods is good, available several different methods forming process, and can carry out secondary processing to goods.In order to further expand the Application of Polyphenylene Sulfide field, people have made extensive work at the aspects such as frictional coefficient raising oilness that reduce polyphenylene sulfide, have obtained the wear-resisting polyphenyl thioether composite material of oilness.It is compared with traditional oilness macromolecular material such as polytetrafluoroethylene (PTFE), polyoxymethylene (POM), polybenzoate (PPHBA), nylon (PA) etc., all is greatly improved at aspects such as machine-shaping, intensity, high temperature resistant, erosion resistance, goods shrinkability and dimensional stabilitys and improves.U.S. Pat 5,962,376, US 5,900,453,5,726,232, it is main and auxiliary carry out compound blend with other organic class oilness materials such as nylon, grease and some mineral-type oilness materials such as molybdenumdisulphide, graphite etc. and prepare the oilness polyphenylene sulfide that Japanese Patent JP 09291297, JP 04178497, JP 07179846, JP 01038471, JP 01038472, JP 58131429, JP 53055361, JP 52129761 generally adopt polyphenylene sulfide and tetrafluoroethylene.But because PTFE specific molecule structure, surface energy is extremely low, nonpolarity, activity is very little, very poor with the consistency of polyphenylene sulfide and other polymkeric substance, and the PTFE particle is easy to reunite, difficulty is uniformly dispersed with the polyphenylene sulfide blend time, thereby cause the interface binding power of PPS/PTFE blend alloy poor, macroface easily takes place to be separated, the direct performance of impact polymer alloy, and cause the processibility of material and lack of homogeneity, frictional coefficient still higher thus, shortcoming such as self lubricity is not enough, goods homogeneity and stability are not ideal enough.
Three, summary of the invention
The objective of the invention is provides a kind of self lubricating wear resistant polyaryl thioether material and preparation method thereof at the deficiencies in the prior art.Be characterized in polyarylene sulfide resin, adding PTFE micro mist, organic and inorganic lubricant filler and compatilizer and prepare self lubricating wear resistant polyaryl thioether composite material.Also can in the process of preparation self lubricating wear resistant polyaryl thioether composite material, add fortifying fibre, so that the self lubricity matrix material that makes meets the different needs.
The present inventor finds:
1, when the naphthalene-sodium solution that adopts tetrahydrofuran (THF) (THF) carries out chemical conversion treatment to PTFE, can make PTFE in treating processes, produce NaF, after other polymer blending, NaF can play coupling agent, sodium can destroy the C-F key simultaneously, remove the lip-deep part F atom of PTFE, make its surperficial defluorinate form a thin coffee-like carburization zone and introduced OH, CO, C=C, COOH isopolarity group, become response type tetrafluoroethylene (R-PTFE), its surface energy increases than PTFE, contact angle diminishes, and wetting property improves, thereby has improved the consistency of material;
2, when the content of PTFE is lower than 3%, the lubricity of matrix material increases limited, when PTFE content surpasses 50%, and the processibility variation of material, and make material property decline to a great extent;
3, when the content of compatilizer is lower than 2%, the compatible effect of storeroom can not demonstrate fully, and when the content of compatilizer is higher than 25%, will influence the mechanical property of matrix material, cause its physical strength to descend, this is because material is subjected to the event of the Effect on Performance of compatilizer own;
4, the adding of organic lubricant filler can effectively improve the lubricity of matrix material, further reduces the frictional coefficient and the wear loss of matrix material, and its effective level has than big-difference according to the difference of tool additive.
5, when the content of inorganic lubricious fillers is lower than 10%, its adding can effectively improve the intensity of matrix material, further reduces the wear loss and the frictional coefficient of matrix material, but when its content surpasses 25%, the processibility of material and mechanical property variation.
6, the shearing rate of raising twin screw extruder helps increasing the consistency of matrix material;
7, when the self lubricating wear resistant polyaryl thioether compound system further with wear-resistant type fortifying fibre compound tense mutually, can make through fibre-reinforced self lubricating wear resistant polyaryl thioether composite material, can greatly improve the physical and mechanical properties and the use temperature of matrix material, further reduce the wear loss of matrix material.
