NOVELTY - Printing coating comprises 20-35 parts mass resin, 10-15 parts mass thermoplastic polyurethane elastic particles wrapped with coated glass powder, 15-25 parts mass inorganic pigment, 5-8 parts mass curing agent and 1-3 parts mass additive agent. USE - The printing coating is used for photovoltaic module. ADVANTAGE - The printing coating has no problem of glass powder falling and excellent reflection effect on light. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the printing coating, which involves (i) placing glass powder with a particle size of 5-10 mu m in a vacuum coating machine under an oscillating environment, and vacuum-plating the surface of the glass powder with silver, (ii) preparing thermoplastic polyurethane elastic particles wrapped with coated glass powder, heating the thermoplastic polyurethane elastic particles with a particle size of 0.01-0.02 mm to a semi-hot-melt state, mixing the semi-hot-melt thermoplastic polyurethane elastic particles and the coated glass powder prepared in step (i) at a mass ratio of 3:1-1:1, and stirring and mixing in a high-speed mixer, and (iii) completely mixing and stirring the resin, the thermoplastic polyurethane elastic particles wrapped with the coated glass powder, the inorganic pigment, the curing agent and the additive agent to form the printing coating.
