Description

technical field [0001] The invention relates to a preparation method of mesoporous graphene oxide / unsaturated polyester molding compound, which belongs to the technical field of polymer composite materials. Background technique [0002] Dry unsaturated polyester molding compound is a thermosetting unsaturated polyester (UP) resin prepared by polycondensation reaction of polyol, polybasic saturated acid and unsaturated acid (anhydride), and then combined with crosslinking agent, reinforcing fiber and other Additives are blended. This type of plastic has excellent mechanical and electrical properties, insulation and heat resistance, and excellent dimensional stability. It is one of the fastest-growing types of electrical plastics in recent years and is suitable for the manufacture of complex and complex insulating structural components in electrical products.

Problems solved by technology

[0003] However, as electrical components continue to develop in the direction of miniaturization, large capacity, multi-function, high reliability, and environmental protection and safety, there are still some deficiencies in the practical application of dry unsaturated polyester electrical plastics, especially in environments with large temperature differences and Under the action of alternating mechanical force (such as the contact bracket of the AC contactor, the switch, the action insulation structure of the thermostat, etc.), the material will be worn and deformed, which will affect the accuracy and reliability of the component action, causing components even the failure of the entire system
