Melt-blowing polyphenylene sulfide non-woven fabric filter material for lowering e-liquid content and preparation method of material

Abstract

The invention discloses a melt-blowing polyphenylene sulfide non-woven fabric filter material for lowering the e-liquid content and application of the material. A preparation method of the filter material specifically comprises the following steps of a, drying of polyphenylene sulfide resin; b, melt-blowing spinning of polyphenylene sulfide; c, collection of polyphenylene sulfide non-woven fabric;d, hot-rolling formation. The melt-blowing polyphenylene sulfide non-woven fabric filter material accounts for 1 / 4-1 of a whole filter rod and preferably accounts for 1 / 3-1 / 2 of the filter rod, the cigarette filter rod has an excellent adsorption effect on e-liquid, the cost is low, and the influence on the taste of cigarettes is small.

Description

technical field [0001] The invention belongs to the technical field of textile material non-woven fabrics, and in particular relates to a melt-blown polyphenylene sulfide non-woven fabric filter material for reducing the amount of tar and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties. PPS fiber has excellent resistance to chemical agents and hydrolysis, as well as flame retardant properties. It can be used as flame-retardant fabric, flue gas filter material, etc. [0003] The currently published patents or documents are all PPS fibers prepared by the melt spinning method, and there are fewer documents for the melt-blown polyphenylene sulfide non-woven fabric filter material with reduced tar content p...

Problems solved by technology

In the prior art, the invention patent with the publication number CN107722274A discloses a preparation method of melt-blown non-woven materials, and specifically discloses that the preparation process of non-woven materials is modified as follows: the temperature of the feeding zone of the screw extruder is 270-310°C , the temperature of the compression zone is 290-330°C, the temperature of the melting zone is 300-340°C, the temperature of the top nozzle is 300-330°C, the temperature of the hot air is 280-330°C, the temperature of the melt blown die is 290-315°C, the temperature of the hot air The pressure is 0.01-0.05 MPa, the speed of the metering pump is 12-25 Hz, and the range of the receiving distance is 15-40 cm. Although this application discloses the preparation of non-woven materials, it has not found that it can be used to reduce tar in cigarette smoke purposes, and a specific method for preparing a filter material for reducing cigarette tar

[0004] For polyphenylene sulfide (PPS), it is used as a filter material in the prior art, but most of them use melt spinning to prepare non-woven fabrics. The method is complicated. The present invention aims to prepare a melt-blown poly The non-woven fabric of phenylene sulfide has a simple preparation process, and it is used as a filter material for cigarettes. The special molecular structure of polyphenylene sulfide is used to achieve excellent adsorption effect of tar
