A recently filed patent (Publication Number: US20230312899A1) describes a thermoplastic resin composition that has potential applications in various industries. The composition includes a thermoplastic resin, such as a polyphenylene sulfide resin, a polystyrene-based resin, or a polyamide resin. It also contains a polyarylene ether modified with a functional group, a coupling agent, and carbon fibers. The thermoplastic resin makes up 80 to 97% of the composition, while the polyarylene ether modified with a functional group accounts for 3 to 20% of the resin component.
In one embodiment, the thermoplastic resin is syndiotactic polystyrene. The coupling agent used in the composition can be a silane coupling agent, an aluminate coupling agent, or a titanate coupling agent. Specifically, an isocyanate-based silane can be used as the coupling agent. Additionally, the composition may include a sizing agent, which has an epoxy group.
The patent also mentions a formed body composed of the thermoplastic resin composition. This formed body exhibits a high strength retention rate after undergoing heat-moisture treatment at 120°C for 500 hours. The strength retention rate is defined as 80% or more, as represented by a specific formula.
Overall, this patent presents a thermoplastic resin composition that combines different materials to achieve desirable properties, such as strength retention and heat resistance. The composition can be used to create various formed bodies for different applications in industries such as automotive, aerospace, and electronics. The specific combination of materials and their proportions in the composition contribute to its unique properties and potential advantages over existing thermoplastic resin compositions.
