Abstract

The invention provides a paint, comprising the following components: 35-60 parts by weight of organic silicon dried heat-resisting paint, 35-60 parts by weight of alcohol acid dried heat-resistant varnish, 25-35 parts by weight of crystalline flake graphite, 10-20 parts by weight of chrysotile asbestos, 30-50 parts by weight of air atomized aluminium powder and right amount of diluent, wherein the diluent is amino paint diluent or dimethylbenzene. The invention also provides a preparation method of the paint and a coating moulding method. The paint provided by the invention is formed by mixing the crystalline flake graphite, the organic silicon dried heat-resisting paint and the like, thus the paint has long life after being coated into a coating, no block stripping, foaming or layering phenomenon is caused, and product quality is greatly improved.

Description

Technical field [0001] The invention relates to the field of coatings and a preparation method of coatings. In addition, the present invention also relates to a coating forming method for coating the workpiece with the above-mentioned paint. Background technique [0002] A seal coating needs to be provided between the turbine blades of the gas turbine unit and related equipment for the seal between the corresponding devices. Such a seal coating requires both good abradability and good erosion resistance Sex. At present, the sealing coating used on gas turbines is generally graphite coating. This type of sealing coating is in contact with the blades during the operation of the gas turbine, and has poor corrosion resistance. It is easy to cause the coating to flake off and the sealing performance is greatly reduced. , And even interrupt the blade. In addition, the manufacture of graphite sealing coating is greatly affected by the environment, and changes in temperature and humid...
