Abstract

The invention discloses a hydrophobic high CTI polyphenylene sulfide composition. The composition comprises the following components in parts by weight: 30-80 parts of polyphenylene sulfide, 10-60 parts of glass fibers, 0.2-2 part of a coupling agent, 0.2-2 part of fluorosilicone oil and 0.1-2 part of an antioxidant. According to the hydrophobic high CTI polyphenylene sulfide composition, the compatibility of PPS and a glass fiber material is improved through the coupling agent, the rigidity and the toughness of the material are further improved, meanwhile, the fluorosilicone oil is added, andthe characteristics of low surface energy and super-hydrophobicity of the fluorosilicone oil are utilized, in the injection molding process, due to the low surface energy, the composition is gatheredon the material surface, and the influence on the rigidity of the material is small. Meanwhile, after the fluorosilicone oil is gathered on the surface, the wetting of the PPS by the electrolyte canbe greatly reduced due to the super-hydrophobic characteristic, and the CTI of the PPS material can be obviously improved.

Description

technical field

[0001] The invention relates to the technical field of engineering plastics, in particular to a polyphenylene sulfide composition with high hydrophobicity and high CTI and its preparation method and application. Background technique

[0002] Polyphenylene sulfide (PPS) has excellent high temperature resistance, dimensional stability, chemical resistance, creep resistance and self-flame retardancy, and is widely used in electronics, automobiles, and precision instruments. However, since the main chain of PPS is composed of a large number of benzene rings, when the PPS surface is discharged, the benzene ring structure will break to generate free radicals, and a conductive carbon layer will be formed on the surface, resulting in poor tracking performance (CTI) of PPS. , In general, the CTI of PPS is less than 150V.

[0003] With the continuous improvement of the safety performance of electronic appliances, the requirements for CTI are getting higher and higher....
