Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] like figure 1 , 2 The shown carbon fiber graphite flexible grounding film is film-like, soft and highly malleable. The appearance of the product can be changed according to actual usage requirements. It has a membrane structure 1 formed by continuous pressing of expanded graphite, and carbon fibers 2 are evenly distributed inside the membrane structure. like Figure 5 The carbon fibers shown are unidirectionally arranged in parallel arrangement 2b o...

Abstract

The invention discloses a carbon fiber graphite flexible ground film and a preparation method thereof. The carbon fiber graphite flexible ground film has a film-shaped structure formed by continuous pressing of expanded graphite, and the carbon fibers are uniformly distributed in the film-shaped structure. The product is membranous and has the characteristics of softness, high plasticity and high tensile strength. The preparation method comprises puffing, gas and material separation, film preparation, wire arrangement, composition, rolling and coiling process. The membranous carbon fiber graphite flexible ground film prepared by the method has the advantages of softness, high plasticity, no falling of graphite sheets, good conductivity, corrosion resistance and a high melting point.

Description

technical field [0001] The invention belongs to the technical field of non-metal lightning protection and grounding, and in particular relates to a carbon fiber graphite flexible grounding film and a preparation method thereof. Background technique [0002] The materials used for the mainstream lightning protection grounding bodies in the market include carbon steel, galvanized steel, copper-clad steel, stainless steel, copper and other metal materials. Among them, carbon steel and galvanized steel have good electrical conductivity, low cost, easy installation, and are widely used in the market. However, carbon steel and galvanized steel buried deep underground generally have a service life of only 5 to 6 years, and are very susceptible to acid and alkali corrosion of the soil and lose their protection. After a tower or substation is struck by lightning, it will cause equipment damage and power failure. [0003] The service life of the copper-clad steel material used mainl...
