Carbon fiber grounding grid anti-corrosive paint and preparation and application methods thereof

Abstract

The invention provides a carbon fiber grounding grid anti-corrosive paint and preparation and application methods thereof. The paint comprises the following components in parts by weight: 30 parts of acrylic resin, 50 parts of dissolving agent, 1.8 parts of epoxy resin, 25 parts of carbon fiber and 5 parts of carbon black serving as conductive filler, 2 parts of diluent, 0.5 part of silane coupling agent, 0.2 part of curing agent and 0.1 part of thickening agent. Strict pretreatment is performed on the surface of a basal body before construction; the surface of the basal body is required to be smooth, dustless and greaseless; the dissolving agent, the conductive filler, the curing agent and the like are required to be fully dissolved during construction; the coating contact is good; the thickness is uniform; the surface is flat; dry environment, ventilation and no pollution are required at a solidification stage; and a coating formed by coating the paint has the advantages of uniformity, compact structure and good conduction performance and has superior corrosion resistance performance.

Description

technical field [0001] The invention relates to a formula and a preparation process of an anti-corrosion coating, in particular to a carbon fiber ground grid anti-corrosion coating and a preparation and application method thereof. Background technique [0002] In addition to excellent electrical conductivity, safety and durability, carbon-based conductive coatings also have the advantages of low cost, non-toxic and harmless, and adjustable resistance. It is a new type of function currently used to replace traditional precious metals such as copper, silver, gold, and nickel. Coatings have broad application prospects. [0003] At present, conductive coatings are required to have high conductivity and strong corrosion resistance. Therefore, further research on carbon-based conductive coatings must improve the formulation from the following two aspects: [0004] 1) Looking for carbon-based conductive fillers with better performance. Carbon fiber is light in weight, high in str...

Problems solved by technology

Traditional binders have few specific functions, and the adhesion needs to be improved. In fact, most of the solvents and curing agents currently used to match the binder will have a relatively large impact on the conductivity of the conductive coating.
