| description | The invention discloses a high CTI (comparative tracking index) polyphenylene sulfide composition prepared on the basis of multi-dimensional formula design and a preparation method and application thereof. The high CTI polyphenylene sulfide composition is prepared from the following components in percentage by weight: 10.5-89.96% of PPS (polyphenylene sulfide) resin; 10 to 50 percent of glass fiber; the filling mineral accounts for 0.01-30%, the hydroxyl gallium oxide accounts for 0.01-5%, and the silane modified epoxy resin accounts for 0.01-1.5%; and 0.01-3% of a stabilizing agent. The invention has the following beneficial effects: the special benzene ring structure of polyphenylene sulfide (PPS) endows the PPS with excellent high-temperature charring performance, but PPS generates a large amount of heat under the action of charges, and carbonization short circuit results in low tracking index (CTI) of the PPS material. The preparation method is simple and suitable for industrial production and application |
