Embodiment 1
[0033] A kind of preparation method of the melt-blown polyphenylene sulfide non-woven filter material that is used to reduce tar amount, described preparation method is carried out according to the following steps:
[0034] a. Drying of polyphenylene sulfide resin
[0035] Drying a certain amount of polyphenylene sulfide resin at a temperature of 100° C. for 24 hours to make the water content less than 0.2%.
[0036] b. Preparation of polyphenylene sulfide
[0037] The dried polyphenylene sulfide resin is fed into the screw area through the hopper, and the uniformly plasticized polyphenylene sulfide melt is obtained by screw extrusion and shearing, and then the melt is filtered and metered to reach the spinneret. When the melt When extruded from the spinneret, it will be drawn into polyphenylene sulfide fibers by hot air. Among them, the basic parameters of the melt-blown equipment are: the length-to-diameter ratio of the screw extruder is 40:1, the feeding zone is 190°C, th...
