Corrosion-resistant, high-temperature-resistant and super-hydrophobic polyphenylene sulfide composite material and preparation method thereof

Abstract

The invention discloses a corrosion-resistant, high-temperature-resistant and super-hydrophobic polyphenylene sulfide composite material, and relates to the technical field of polyphenylene sulfide composites, the corrosion-resistant, high-temperature-resistant and super-hydrophobic polyphenylene sulfide composite material is mainly prepared from the following raw materials by mass: 20-40% of polyphenylene sulfide resin, 10-30% of a modified filler, 10-30% of polytetrafluoroethylene, 10-20% of a silane coupling agent, 5-10% of a compatilizer, and 5-10% of stearic acid; and the preparation method of the modified filler comprises the following steps: mixing and stirring hydroxyl silicone oil, tetraethyl orthosilicate, dibutyltin dilaurate and hexane according to a mass ratio of 5: 1: 0.1: 100, then adding inorganic nanoparticles, stirring, filtering, washing and drying to obtain the modified filler. The invention also provides a preparation method of the polyphenylene sulfide composite material. The polyphenylene sulfide composite material disclosed by the invention has the beneficial effects that the polyphenylene sulfide composite material has very high heat resistance, corrosion resistance and hydrophobicity due to the adoption of the raw materials in percentage by mass and a synergistic effect among the raw materials.

Description

technical field [0001] The invention relates to the technical field of polyphenylene sulfide composite materials, in particular to a corrosion-resistant, high-temperature-resistant, superhydrophobic polyphenylene sulfide composite material 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, and chemical resistance. Therefore, it is made into pipes, fibers, coatings, etc. and is used in various fields. With the development of the times, the purpose and use environment of PPS become more and more complex, so the performance requirements of PPS are also getting higher and higher, and a single performance often cannot meet the needs of actual production, so researchers put Focus on the research and development of PPS materials with various properties. [0003] The patent application with publication num...
