Technical Field

[0001] The invention relates to the technical field of metal materials, in particular to a new insulating material. Background Art

[0002] With the rapid development of my country's economy, the use of insulating materials has become more and more extensive. Insulating materials are widely used in electricity, electronics, telecommunications, transportation, construction and other fields. At the same time, insulating materials are one of the necessary materials to ensure the stable operation of electrical equipment and the safety of passengers. Its main function is to isolate the conduction of electricity and prevent electrical leakage and loss. There are many types of insulating materials, among which the common ones include fluoroplastics, polyolefins, polyimides, silicone rubber, PET, etc. Different types of insulating materials have different insulation, conductivity, heat resistance, corrosion resistance and other characteristics, so they have been widely used in different electrical equipment.

[0003] However, most traditional insulating materials do not have strong enough mechanical properties, so in actual use, the insulating materials are prone to surface cracking and damage, which can easily cause leakage hazards during long-term use of electrical equipment. At the same time, most traditional insulating materials are prone to oxidation and thermal degradation due to long-term exposure to the air, which can easily affect their insulation effect and have an adverse effect on the long-term use of electrical equipment. Therefore, technical improvements are urgently needed. Summary of the invention
