Abstract

The invention relates to the field of electric control boxes, and particularly discloses a corrosion-resistant electric cabinet for wind power generation and a preparation method of the corrosion-resistant electric cabinet. The corrosion-resistant electric cabinet for wind power generation comprises an electric cabinet body and is characterized by further comprising a corrosion-resistant coating coated on the surface of the electric cabinet body, the corrosion-resistant coating comprises a primer layer, a middle paint layer and a finish paint layer, the primer layer is in contact with the electric cabinet body, and the middle paint layer is located between the primer layer and the finish paint layer; the finish paint layer is prepared from the following components in parts by weight: 50 to 60 parts of acrylic resin, 3 to 6 parts of boron nitride, 5 to 10 parts of modified silicon carbide, 10 to 15 parts of modified nano zinc oxide crystal, 15 to 20 parts of titanium dioxide, 0.5 to 1.0 part of dispersing agent, 10 to 15 parts of anti-settling agent, 6 to 10 parts of acetone and 1 to 1.5 parts of defoaming agent. The corrosion-resistant electric cabinet for wind power generation has the advantages of being suitable for being used in the marine atmospheric environment, excellent in corrosion resistance and high in thermal stability.

Description

technical field [0001] This application relates to the technical field of electric control boxes, more specifically, it relates to a corrosion-resistant electric control box for wind power generation and its preparation method Background technique [0002] my country's usable marine wind energy resources are about 750GW, which is three times that of land wind energy resources. The annual average utilization hours can reach more than 3000h, and the annual power generation is 50% higher than that of land wind energy resources. Offshore wind power technology has become a hot spot in the research and application of wind power technology in my country. [0003] The electric control box is a one that contains one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, and is completely assembled by the manufacturer to complete all internal electrical and mechanical connections. combination. [0004] When the electric c...
