Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a novel insulating composite material and a preparation method thereof. Background technique [0002] Insulating material, also known as dielectric, refers to a substance that is non-conductive or conductive under the action of DC voltage. The main function of insulating material is to isolate electrical conductors with different potentials in electrical equipment, so that current can flow according to a certain path. , It can also be mechanically supported and fixed, as well as moisture-proof, mildew-proof and conductor-protecting. [0003] Insulating materials are the basis and guarantee for the development of electrical products, and play a particularly important role in the development of motors and the electrical industry. They are the key to the advanced technology of electrical products and an important guarantee for the safe and reliable operation of electric...
