Problems solved by technology

The above-mentioned anti-corrosion materials generally have certain anti-corrosion properties, but the mechanical properties, thermal stability and flame-retardant properties often fail to meet the expected requirements; there are also some anti-corrosion materials whose anti-corrosion indicators are unqualified, for example, they can only prevent acid and alkali Corrosion, or can only prevent radiation, various indicators often cannot be taken into account
In order to overcome the above defects, many types and compositions of electric anti-corrosion materials have been prepared in the prior art; for example, Chinese invention patent CN201210457641 discloses an anti-corrosion cable, which has a central conductor, a refractory mica tape wrapping the conductor, and a silicone rubber insulation Layer, water-blocking tape and anti-corrosion coating; the anti-corrosion cable has a certain anti-corrosion performance, but the preparation process is complicated and the cost is high, so it is not suitable for large-scale industrial production

Description

[0001] technical field [0002] The invention belongs to the field of new materials and relates to a power material, in particular to a corrosion-resistant power material and its application. [0003] Background technique [0004] Electric anti-corrosion materials have a wide range of applications, and are suitable for use under harsh and extreme conditions such as acid, alkali, salt, high temperature, and radiation. Electric anti-corrosion materials are a kind of special materials, which can be defined as materials used to make electric power materials corrosion-resistant when used. Anti-corrosion performance is only the basic performance that electric anti-corrosion materials should have, and its mechanical properties, thermal stability and flame retardancy are equally important. [0005] At present, electric anti-corrosion materials are mainly made of plastic plates, and plastics are synthetic polymer compounds, which can freely change the shape and style. Plastic is a...
