Embodiment 1
[0034] A damping coating for automobile chassis armor, comprising the following raw materials:
[0035] 150 parts of acrylic waterproof emulsion, 50 parts of antirust emulsion, 100 parts of plasticized acrylic emulsion, 150 parts of pure acrylic emulsion, 15 parts of propylene glycol phenyl ether, 100 parts of mica powder, 25 parts of floating beads, 75 parts of talc powder and 300 parts of silica powder 25 parts of ammonium octamolybdate, 25 parts of preservative, 5 parts of black pulp and 2 parts of alkaline silica sol.
[0036] Wherein, the acrylic waterproof emulsion is German BASF waterproof emulsion S 400F.
[0037] The pure acrylic emulsion has a solid content of 30±2%, a pH of 7-7.5, a glass transition temperature of -5°C, a minimum film-forming temperature of 0°C, and a viscosity of less than 20cps. Low solid content and low viscosity can increase the amount of fillers and reduce costs.
[0038] The anti-rust emulsion is DL-1065 anti-rust emulsion produced by Beijin...
