Beschreibung
Zusammenfassung:	The present invention discloses a SiO2-containing reinforced composite chemical plating liquid, wherein 1 L of the SiO2-containing reinforced composite chemical plating liquid comprises 20-40 g/L of nickel sulfate, 20-45 g/L of sodium hypophosphite, 15-30 g/L of citric acid, 3-10 ml/L of propionic acid, 15-25 g/L of sodium acetate, 10-100 mg/L of potassium iodide, 1-5 mg/L of a surfactant, and 3-20 g of SiO2. The present invention further discloses a preparation method of the plating liquid, applications of the plating liquid, and a method for carrying out low temperature sulfuric acid dew point corrosion resistance by using the plating liquid, wherein a plating layer prepared by using the SiO2-containing reinforced composite chemical plating liquid has a high low temperature sulfuric acid dew point corrosion resistance performance.
