Description

technical field [0001] The invention relates to an engineering plastic, in particular to a high-temperature-resistant high-performance engineering plastic and a preparation method thereof. Background technique [0002] Engineering plastics refer to a class of high-performance polymer materials that can be used as structural materials, withstand mechanical stress in a wide temperature range, and be used in harsh chemical and physical environments. Engineering plastics must be able to withstand certain external forces, have good mechanical properties and dimensional stability, and maintain their excellent properties at high and low temperatures, and can be used as plastics for engineering structural parts. [0003] At present, the improvement of high temperature resistance performance of engineering plastics is a hot and difficult point of research. It is difficult to improve the temperature resistance of existing engineering plastics in order to achieve better uses. Content...
