NOVELTY - Sealing liquid comprises 30-55 wt.% component A and 50-85 wt.% component B. The component A comprises 0.5-3 wt.% graphene, 5-15 wt.% nano potassium silicate, 2-6 wt.% nekal powder, 1-5 wt.% TX-10 and balanced amount of water. The component B comprises 12-20 wt.% aluminium dihydrogen phosphate, 1-3 wt.% titanium pigment, 0.3-1 wt.% sodium molybdate, 3-15 wt.% zinc sulfate, 2-10 wt.% phosphoric acid and balanced amount of water. USE - Sealing liquid for mechanical galvanized bolt. ADVANTAGE - After the mechanically galvanized bolts are treated with the sealing solution, completely covered sealing film with a sense of lubricity is formed on the surface of the bolts. The time for the white rust to appear in the neutral salt spray test is significantly prolonged and no zinc powder fell off after the bolt thread is assembled.
