The invention relates to relates to the technical fields of lead-cadmium-free glass powder and printing ink and particularly relates to lead-cadmium-free compound glass powder for printing ink for a windshield of an automobile. The lead-cadmium-free compound glass powder is characterized by being prepared by adequately mixing Bi2O3-B2O3-SiO2 system glass powder with Nb2O5-ZnO-B2O3-SiO2 system glass powder in a mass ratio of (2-5) to 1, wherein the Bi2O3-B2O3-SiO2 system glass powder comprises the following components in percentage by weight: 10%-45% of Bi2O3, 8%-30% of B2O3, 20%-50% of SiO2, 3%-15% of ZnO, 2%-8% of Na2O and 2%-8% of K2O; and the Nb2O5-ZnO-B2O3-SiO2 system glass powder comprises the following components in percentage by weight: 8%-22% of Nb2O5, 10%-30% of ZnO, 20%-45% of SiO2, 6%-20% of B2O3, 0.5%-4% of MoO3, 0.5%-4% of TiO2, 5%-15% of Na2O, 0.2%-2% of K2O, 1%-5% of Li2O, 0.2%-2% of ZrO2 and 0.2%-2% of Al2O3. The prepared compound glass powder is applied to the printing ink for the windshield of the automobile, so that the printing ink can be adequately fused at 600-650 DEG C in a sintering process, does not crack, is good in glossiness and high in blackness and further has excellent water resistance and acid-base corrosion resistance.
