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.
