The invention provides a preparation method of a protective coating based on a working surface of a mould matrix. The preparation method comprises the steps that 1) first paint is sprayed on the working surface of the mould matrix to form a hard wear-resistant coating; 2) an inward sunk microstructure is prepared on the surface of the hard wear-resistant coating; and 3) second paint is sprayed on the surface of the hard wear-resistant coating to form a lubricant coating, thereby accomplishing the preparation of the protective coating based on the working surface of the mould matrix. With the adoption of the preparation method, the protective coating having high bonding strength, wear resistance and lubricating property can be prepared on the working surface of the mould matrix, the problem that the interface bonding strength between the traditional hard wear-resistant layer and the traditional lubricant coating is low is solved, and the life of a mould is prolonged.
