Abstract

The invention relates to a liquid surface conditioning agent which is used for promoting formation of a phosphating film on a metal surface. The liquid surface conditioning agent comprises the following ingredients by mass percentage: 37-47% of purified water, 10-15% of phosphopeptide compound, 35-40% of phosphate, 1% of polyoxyethylene ether, 6% of alkaline reagent, and 0.7-2% of surfactant containing R2-N<-R1>-CH2COOH, wherein the surfactant containing R2-N<-R1>-CH2COOH comprises an amino acid surfactant and a thionothiolic acid surfactant. The subsequent quick formation of a phosphating film coating is significantly promoted by adding the surfactant containing R2-N<-R1>-CH2COOH into a titanium phosphate mixture and adjusting a proportion of a sodium-containing phosphate and potassium-containing phosphate mixture at the same time; the adhesion and coverage of the phosphating film coating are facilitated; a technical flow is simple; the storage time is long; and the conditioning agentis convenient to operate and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of surface regulators, in particular to a liquid surface regulator and a preparation method thereof. Background technique [0002] At this stage, in order to obtain dense and fine phosphate coating crystals on the metal surface, surface adjustment treatment is required before phosphating to activate the metal surface and generate crystal nuclei for depositing phosphate coating crystals on the metal surface to promote Phosphate film formation speed and increase the coverage and compactness of the film layer, thereby promoting the organic combination of the subsequent coating and the phosphate film layer, and improving the adhesion and corrosion resistance of the coating; at present, most of the prior art The powdered surface conditioner is still used, but the powdered surface conditioner disperses slowly in the aqueous solution, the concentration of the effective colloidal titanium salt formed is low, the sus...
