Problems solved by technology

[0009] The purpose of the present invention is to study a process for coating the surface of polyphenylene sulfide fiber with an inorganic reinforcement layer to solve the problems that polyphenylene sulfide fiber will appear at higher temperatures, such as: its mechanical properties are reduced, and at the same time the fiber is durable. The high temperature capability has been improved, and it can be kept in an environment with a temperature of 200-265°C for a long time (more than 200 hours, or even longer), and the mechanical properties of its polyphenylene sulfide fiber remain basically unchanged.

Abstract

The invention discloses a technique method of coating an inorganic strengthening layer on the surface of polyphenylene sulfide fiber. Polyphenylene sulfide fiber precursor is synthesized from raw materials of sodium sulfide and p-dichlorobenzene and spinned by melt spinning. The hot stretching treatment is implemented on the fiber precursor to obtain finished fiber. Then, the finished fiber is impregnated and pre-coated. Isopropanol solution containing one of film forming matters of lactic acid titanium, triethanolamine titanium, aluminum acetylacetonate, Zirconium Butoxide and zirconium n-propoxide is used for impregnated material. After the air drying at 20 DEG C and the heat treatment at 600-760 DEG C and normal pressure, the inorganic strengthening layer which is 1-100 micrometers is obtained on the surface of the polyphenylene sulfide fiber. Then, polyphenylene sulfide composite fiber which is provided with the inorganic strengthening layer on the surface is obtained. The polyphenylene sulfide composite fiber obtained through the method of the invention is provided with high temperature strength retention and is especially applicable to professional filtering materials which are professionally used for thermal power generation, waste incinerators, chemical filtering, etc.

Description

Technical field [0001] The invention belongs to the field of production and application of special fibers. Background technique [0002] High-performance polyphenylene sulfide has excellent chemical resistance and thermal stability at high temperatures, and has flame retardancy, insulation, radiation resistance and good mechanical properties. In order to expand the scope of use of this material, researchers from various countries have been looking for new methods to make it fiberized. [0003] PPS fiber has good chemical stability, it can still maintain its original performance under extremely harsh conditions, and has outstanding chemical stability, second only to polytetrafluoroethylene fiber. At high temperature, it can maintain the original tensile strength after being placed in different inorganic reagents for a week. It also has good resistance to organic solvents. Except that toluene at 93°C has a slight influence on its strength, in organic solvents such as carbon ...
