Abstract

The invention relates to an antistatic, wear-resistant and high-performance PS composite material and a preparation method thereof. The antistatic, wear-resistant and high-performance PS composite material is prepared by, by weight, 60-80 parts of PS, 20-30 parts of modified nano ZrO2, 10-16 parts of antistatic agent, 0.1-0.5 part of compatibilizer, 0.1-0.5 part of antioxidant and 0.1-0.3 part of lubricating agent. The antistatic, wear-resistant and high-performance PS composite material has the advantages that due to the fact that the nano ZrO2 is grafted by poly-butyl acrylate (PBA), a PBA organic coating layer can be formed on the surface of the nano ZrO2, a strong three-dimensional protection effect is generated, ZrO2 agglomeration is prevented, the ZrO2 can be evenly dispersed in a PS matrix, and the mechanical performance of the PS composite material is increased.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to an antistatic and wear-resistant high-performance PS composite material and a preparation method thereof. Background technique [0002] Polystyrene (PS), as a common thermoplastic, is widely used. However, with the development of science and technology, in some specific fields, people have higher and higher performance requirements for PS materials, especially wear resistance, antistatic performance and mechanical properties, which greatly limits the application of PS composite materials in these special fields. on the application. [0003] Nano-zirconium dioxide (ZrO) grafted with polybutylacrylate (PBA) 2 ), and then modify the PS to improve the wear resistance, antistatic performance and physical properties of the PS composite material. This method has not been reported so far. Contents of the invention [0004] The purpose of the present invention is to provide...
