Abstract

The present invention relates to a method for the composite coating of a wind generating set brake disc, and solves the problems of single coating, poor anticorrosion effect, and short service life existing in current surface treatment technologies of wind generating set brake discs. The method comprises: first conducting cleaning and sandblasting treatments on the surface, except the brake friction surfaces, of a brake disc so as to make the brake disc have a clean surface; then carrying out zinc spraying treatment on tower tube flange butt contact surfaces so as to endow the flange connecting the tower tubes with lightning protection and grounding functions under the premise of corrosion resistance; then spraying a primary coat, an intermediate coat, and a finishing coat on the outer lateral wall of the brake disc so as to meet the corrosion prevention, ageing resistance and other demands of the brake disc in a complex natural environment; and finally spraying a primary coat and an intermediate coat on engine flange butt contact surfaces so as to provide anticorrosion protection and shielding effect. The composite coating obtained by the method of the invention has the advantages of high elasticity, high wear resistance, high weatherability, as well as good adhesion and medium resistance, etc.

Description

technical field [0001] The invention relates to a brake disc of a wind power generator, in particular to a composite coating method for a brake disc of a wind power generator. Background technique [0002] According to the information released by China Wind Power Engineering Information Network, my country's wind energy industry has developed rapidly in recent years. In 2010, a total of 802 wind farms were built across the country (excluding Hong Kong, Macao, and Taiwan), and the total capacity of wind power construction in the country (has been connected to the grid or the supporting projects of wind farms have been completed, and the hoisting capacity that basically meets the conditions for grid connection) is 38.28 million kW. The grid-connected operating capacity is 31.31 million kW. The world ranking of my country's wind power installed capacity has risen from the third place in 2009 to the current first place. Officials from the National Energy Administration stated ...
